The Pacific Islands region is home to several of the world's biodiversity hotspots, yet its unique flora and fauna are under threat because of biological invasions. These invasions are likely to proliferate as human activity increases and large‐scale natural disturbances unfold, exacerbated by climate change. Remote sensing data and techniques provide a feasible method to map and monitor invasive plant species and inform invasive plant species management across the Pacific Islands region. We used case studies taken from literature retrieved from Google Scholar, 3 regional agencies’ digital libraries, and 2 online catalogs on invasive plant species management to examine the uptake and challenges faced in the implementation of remote sensing technology in the Pacific region. We synthesized remote sensing techniques and outlined their potential to detect and map invasive plant species based on species phenology, structural characteristics, and image texture algorithms. The application of remote sensing methods to detect invasive plant species was heavily reliant on species ecology, extent of invasion, and available geospatial and remotely sensed image data. However, current mechanisms that support invasive plant species management, including policy frameworks and geospatial data infrastructure, operated in isolation, leading to duplication of efforts and creating unsustainable solutions for the region. For remote sensing to support invasive plant species management in the region, key stakeholders including conservation managers, researchers, and practitioners; funding agencies; and regional organizations must invest, where possible, in the broader geospatial and environmental sector, integrate, and streamline policies and improve capacity and technology access.

The Tricolored Bat is an imperiled species due to white-nose syndrome. There is limited information available on roosting and foraging area use of the species to support planning and management efforts to benefit recovery in the Southeastern United States. Female tricolored bats exit hibernation and allocate energy toward disease recovery, migration, and reproduction. Providing and managing for summer habitat is 1 strategy to promote recovery. We sought to: (1) determine local- and landscape-scale factors that influence female Tricolored Bat roost selection; (2) quantify land cover use in core and overall foraging areas; and (3) define foraging area size and distances traveled by female tricolored bats in Tennessee. Bats in this study roosted in trees of variable sizes, in multiple tree species with large canopy volumes, and almost always roosted in trees with dead leaf foliage suspended in the canopy. Forest plots used by bats had trees averaging 30 cm diameter at breast height, basal areas averaging 27 m2/ha, contained multiple tree species, and comprised around a 50:50 ratio of canopy and subcanopy trees. Bats did not roost in coniferous forest areas and were only located in deciduous and mixed forest areas. Bats foraged near and directly over water, in open areas, and along forest edges. This study increases our knowledge on habitat requirements of the species in a temperate region dominated by unfragmented forests and many large water bodies and serves a baseline for management and efforts to benefit survival, reproduction, and population recovery.

Reintroduction projects are gaining popularity; however, their relatively elevated cost and chance of failure make them debatable, hence assessing their effectiveness is essential. Within the early stages of raptors, the post-fledging dependency period (PFDP) is the one in which individuals must face dangers without having completely developed their skills. Thereby, comparing PFDP patterns concerning reintroduced and wild individuals is of major interest as it would help to plan and improve future conservation actions. We analyzed the behavior of 38 juvenile Bonelli's Eagles (Aquila fasciata) (15 reintroduced and 23 wild) tracked through GPS telemetry, tagged as nestlings in two insular environments. The study period encompassed 9-yr movement data from reintroduced chicks in Mallorca (Spain) and wild chicks from Sicily (Italy). Movement parameters (i.e., age of first flight, age of dispersal, length of the PFDP, revisits to the natal or release area, and residence time in them) were analyzed together with their behavior for reintroduced and wild individuals. Similar movement patterns were obtained for both origins, although wild individuals revisited the natal site more often and dispersed earlier. Behavior was also similar, though it varied throughout the PFDP, observing a more abrupt progress in wild individuals and an earlier development of travelling and hunting behaviors. Observed differences are probably related to food availability, which can improve body condition and thus delay onset of dispersal, together with parental presence, which can prompt an earlier ending of the PFDP by encouraging juvenile independence. In conclusion, our study provides valuable insights into the behavior of reintroduced Bonelli's Eagles during their PFDP and how it compares to their wild counterparts. Our results suggest that reintroduced individuals can successfully adapt to their environment and behave similarly to wild individuals. These findings can aid in the planning and improvement of future reintroduction projects and conservation actions for this endangered species. [ABSTRACT FROM AUTHOR]

Permanent pacemakers are a frequently used therapeutic modality. Its use has had a great impact on the morbidity and mortality and quality of life of patients with heart rhythm disturbances, with an exponential increase observed in recent decades. The use of this strategy presents different phases, in which follow-up throughout the useful life of the device is a fundamental and determinant pillar of the efficacy and safety of this therapeutic modality. This review seeks to provide a clear and structured update of the fundamental aspects to consider in the follow-up of all patients with pacemakers. The follow-up of the patient with a pacemaker must follow a complete, systematic and periodic protocol, evaluating aspects and parameters related to the patient and the pacemaker, in order to ensure the proper and safe operation of the device adapted to the person.

The competitiveness that companies face in the market becomes more and more intense, so it is of great importance that processes are carried out efficiently, minimizing losses. In mining, the exploration phase allows for cost reduction with good management of ore and waste loading and transport operations for the subsequent stages of the production process. The transport of these materials is mostly done by trucks, whose productivity is directly influenced by the average speed. This work defined, created tools and dashboards for managing average speed, enabling better management of team performance and mapping and field work to improve access conditions. The results of the work showed an increase in productivity of 13% for the Caterpillar fleet and 10.8% for the Komatsu fleet. A reduction in diesel consumption of 600 thousand liters in two years was evidenced, contributing to sustainability by reducing CO2 emissions. Improvements were also identified in the safety and ergonomics of the roads and standardized direction of access maintenance resources. [ABSTRACT FROM AUTHOR]

The consumption and generation of electricity must be carried out intelligently, taking advantage of the technologies of the fourth industrial revolution, even more so on university campuses where sustainable development strategies must be innovated. Microgrids allow the management of the different elements of an electrical network, but it is necessary to implement the generation and measurement elements properly. This article shows the configuration of a microgrid on a university campus, as well as the configuration of telemetry and monitoring of the different variables of the system. [ABSTRACT FROM AUTHOR]

Studies on the migratory behavior of songbirds are important to inform full annual cycle conservation. We remotely tracked the early fall migratory movements of both juvenile and adult Savannah Sparrows (Passerculus sandwichensis) that were tagged on their natal/breeding territories in southwestern Ontario, Canada, where the Motus Wildlife Tracking System has the highest density of automated receivers in North America. Our primary aims were to describe and compare adult and juvenile migratory movements during the early part of migration, compare frequency of detection of juveniles versus adults as a proxy for minimum apparent survival, and describe potential migration routes and overwintering areas. Juveniles initiated migration approximately a month earlier than adults. Both juveniles and adults typically made their first migratory flight in a southwest direction, but some juveniles displayed subsequent exploratory movements that were not in a southwest direction, potentially to collect information for next year's breeding site selection. Detection rates early in migration were similar, but low, for adults and juveniles (34% and 39% respectively), suggesting that juveniles that had survived the fledgling period likely did not experience high mortality during the subsequent 2 months prior to their fall migration. Long-distance detections of 2 adults preliminarily suggest that individuals from this southern Ontario breeding region may travel west of the Appalachian Mountains along the Mississippi flyway during fall migration. Our study aligns with previously reported patterns of age-specific migratory behavior from other Savannah Sparrow populations and contributes to our overall understanding of the migratory ecology of this species.

Daily activity patterns are a fundamental component of a species' biology and have implications for numerous elements of organismal function. Because these patterns may be affected by environmental conditions, the setting in which activity data are collected is critical. Although the daily activity patterns of the Velasco tuco-tuco (Ctenomys famosus) have been studied extensively in the laboratory and in semi-natural enclosures, no information on activity is available for free-living members of this species. To characterize activity by these subterranean rodents in their natural environment, we used radiotelemetry to record the locations of 17 adults at hourly intervals for 72 consecutive hours. These data revealed a tendency for members of the study population to be diurnal, with individuals changing locations more often, traveling farther between radio fixes, using larger areas, and spending less time in putative nests during daylight hours. Diurnality index values calculated for these animals also suggested greater daytime activity. Although diurnal behavior has been reported for free-living populations of several other ctenomyid species monitored by radiotelemetry, the strength of this tendency appears to vary, raising interesting questions about the factors that determine daily activity patterns in the genus Ctenomys.

Background. The aim of the study was the evaluation of the structural and functional reorganization of the heart and their relationship with physical activity in elite football players. Material and methods. Characteristics of the myocardium and physical activity were studied using the Catapult Vector S7 GPS-sport telemetry system, "Polar" heart rate monitor, and echocardioscope. Results. Physical activity in the mode of high-speed running during games was found to contribute to an increase in playing activities of football players and structural and functional characteristics of the heart. A correlation (r=0.35-0.51; p=0.021-0.043) was obtained between the performance of football players, which was measured by distance, heart rate, cardiac output, stroke volume, stroke index, left ventricle mass. Statistically significant differences were found in the structural and functional characteristics of the myocardium: end-diastolic volume, endsystolic volume, stroke volume, stroke index, ejection fraction, myocardial contractility index, and left ventricle mass for groups of players with different gradations of distance in the mode of high-speed running. Conclusions. It was found that there is a relationship between the physical activities of highly qualified football players in the mode of speed running with the characteristics of the pumping function of the heart.

Atmospheric probes are widely used for the acquisition of various atmospheric variables with purposes from weather forecasting to aeronautical safety. These, however, have a high acquisition cost because they are imported. Therefore, in this work, the result of a launching of a probe developed using low-cost materials with very interesting results will be exposed. The telemetry technology used allowed for long-distance communication in a way. In addition, this project aimed to get students involved in the various stages of the project, from planning, construction, launch, recovery and analysis of meteorological data obtained.

Near‐term ecological forecasting has the potential to mitigate negative impacts of human modifications on wildlife by directing efficient action through relevant and timely predictions. We used the U.S. avian migration system to highlight ecological forecasting applications for aeroconservation. We used millions of observations from 143 weather surveillance radars to construct and evaluate a migration forecasting system for nocturnal bird migration over the contiguous United States. We identified the number of nights of mitigation required to reduce the risk of aerial hazards to 50% of avian migrants passing a given area in spring and autumn based on dynamic forecasts of migration activity. We also investigated an alternative approach, that is, employing a fixed conservation strategy based on time windows that historically capture 50% of migratory passage. In practice, during both spring and autumn, dynamic forecasts required fewer action nights compared with fixed window selection at all locations (spring: mean of 7.3 more alert days; fall: mean of 12.8 more alert days). This pattern resulted in part from the pulsed nature of bird migration captured in the radar data, where the majority (54.3%) of birds move on 10% of a migration season's nights. Our results highlight the benefits of near‐term ecological forecasting and the potential advantages of dynamic mitigation strategies over static ones, especially in the face of increasing risks to migrating birds from light pollution, wind energy infrastructure, and collisions with structures.

Future researchers using SRS-derived data must seek to validate long-term habitat mapping data via available ground-truthed data or expert information prior to their inclusion in AOO and habitat availability quantification (as per IUCN 2019a). It is clear that SRS can play a major role in producing information on changing habitat extent and quality for the RLI (Rondinini et al. 2014) and in automating range-based RLS assessments, especially for those species affected primarily by habitat loss.

A significant limitation in biodiversity conservation has been the effective implementation of laws and regulations that protect species' habitats from degradation. Flexible, efficient, and effective monitoring and enforcement methods are needed to help conservation policies realize their full benefit. As remote sensing data become more numerous and accessible, they can be used to identify and quantify land‐cover changes and habitat loss. However, these data remain underused for systematic conservation monitoring in part because of a lack of simple tools. We adapted 2 algorithms that automatically identify differences between pairs of images. We used free, publicly available satellite data to evaluate their ability to rapidly detect land‐cover changes in a variety of land‐cover types. We compared algorithm predictions with ground‐truthed results at 100 sites of known change in the United States. We also compared algorithm predictions to manually created polygons delineating anthropogenic change in 4 case studies involving imperiled species' habitat: oil and gas development in the range of the Greater Sage Grouse (Centrocercus urophasianus); sand mining operations in the range of the dunes sagebrush lizard (Sceloporus arenicolus); loss of Piping Plover (Charadrius melodus) coastal habitat after Hurricane Michael (2018); and residential development in St. Andrew beach mouse (Peromyscus polionotus peninsularis) habitat. Both algorithms effectively discriminated between pixels corresponding to land‐cover change and unchanged pixels as indicated by area under a receiver operating characteristic curve >0.90. The algorithm that was most effective differed among the case‐study habitat types, and both effectively delineated habitat loss as indicated by low omission (min. = 0.0) and commission (min. = 0.0) rates, and moderate polygon overlap (max. = 47%). Our results showed how these algorithms can be used to help close the implementation gap of monitoring and enforcement in biodiversity conservation. We provide a free online tool that can be used to run these analyses (https://conservationist.io/habitatpatrol). Article impact statement: The use of satellite images to automatically detect habitat loss improves enforcement of conservation policy. [ABSTRACT FROM AUTHOR]

Background. The physical activity of 29 football players using either aerobic or anaerobic energy regimes was tested during official games and in the laboratory. Material and methods. Under conditions of gradually increasing power on a treadmill, maximal running speed (V, km/h), oxygen consumption (VO2, mL/min/kg), heart rate (HR, beats/min), and anaerobic metabolism threshold (AT mL/min/kg) were determined, and blood lactate (BLact, mmol/L) was measured. Results. The correlation between the total length of distance run during the game and treadmill running speed for the outcome measures were as follows: anaerobic metabolism threshold, r=0.54 (p=0.032), BLact, r=0.37 (p=0.034), VO2max, r=0.41 (p=0.027), and HR, r=0.36 (p=0.047). We found aerobic mechanisms were dominant in ensuring the game activity of football players. Specifically, aerobic mechanisms contribute roughly 32.4-43.8% to playing activity, while aerobic-anaerobic energy supply mechanisms provide for only 17%. Lactic and alactic mechanisms provide for 5.6% and 1.6%, respectively. Conclusions. The results provide valuable information on the relationship between football play activity and aerobic and anaerobic energy supply mechanisms. Enhancing the functionality of the anaerobic lactic-alactic energy system can lead to growth and improvements in physical performance in football players. [ABSTRACT FROM AUTHOR]

Large-scale conversion of uncultivated land to agriculture threatens wildlife and can diminish ecosystem services provided by nature. Understanding how wildlife provision ecosystem services may incentivize wildlife conservation in agricultural landscapes. Attracting Barn Owls (Tyto furcata) to nest on farms for pest management has been implemented worldwide but has not been evaluated in vineyard agroecosystems. Napa Valley, California, is a renowned winegrape growing region, and viticulturists encourage Barn Owl occupancy to help minimize damage from Botta's pocket gophers (Thomomys bottae) and voles (Microtus spp.). This study modeled the use of habitats in space and time by hunting Barn Owls, providing information about their potential to provide the critical ecosystem service of pest consumption. We used global positioning system tags to track hunting owls and used a resource selection function to compare used and available habitats. We constructed the intensity of use and home range-movement maps using a time local convex hull analysis from location data. We found that Barn Owls selected uncultivated habitats when hunting, some of which were relatively rare on the landscape. Approximately, one-third of Barn Owl hunting locations occurred in vineyards, but this use was out of proportion to the availability of vineyards, which comprised 50% of the area around nest boxes. The owls' use of vineyards increased with decreasing amount of selected uncultivated habitat in the landscape. However, as reported by a previous study, the occupancy of nest boxes in vineyards increases with uncultivated habitats nearby. Future research should model landscape composition to determine the amount of preferred habitat necessary to support occupancy as well as hunting in vineyards. A true test of pest management by Barn Owls awaits experimentation coupled with monitoring rodent populations. [ABSTRACT FROM AUTHOR]

Este articulo muestra la construcción de un modelo de información para el intercambio de datos e información dentro del contexto del desarrollo de sistemas satelitales de tipo CubeSat. Se articulan el desarrollo, procedimiento, descripción, diseño, arquitectura y los resultados que refieren en gran medida a la adopción de dichos lineamientos en un escenario de interoperabilidad tecnológica. De igual manera, se puntualiza la funcionalidad en los esquemas de trasmisión de información de telemetría en satélites académicos. Se tienen en cuenta los lineamientos del Comité Consultivo para Sistemas de Datos Espaciales (CCSDS), en colaboración con la Agencia Espacial Europea (ESA) y la entidad de Cooperación Europea para la Normalización Espacial (ECSS), las cuales han consolidado múltiples recomendaciones para normalizar la transferencia de información de sistemas espaciales a través de varios procedimientos y mecanismos. Adicionalmente, se consideró el lenguaje de marcado extensivo (XML), junto al formato de intercambio de telemetría y comando (XTCE), en conjunto con el estándar de utilización de paquetes (PUS), la descripción de los servicios de operación de misión (MO) y la capa de abstracción de mensajes (MAL), teniendo en cuenta que sugieren la modularidad y especificidad necesaria para el desarrollo y construcción de sistemas de información en tecnologías satelitales.

El rayador (Rynchops niger) visita las costas de Chile durante los veranos australes, observándose en bandadas de distinto tamaño principalmente en humedales costeros. Por medio del uso de una base de datos de observaciones de ciencia ciudadana junto a nuestros monitoreos de largo plazo, estimamos que el tamaño poblacional promedio para la especie en Chile alcanzó los 10.227 individuos entre 2014 y 2018. Tres sitios (estuarios de los ríos Mataquito, Itata, y Tubul) congregaron a más del 50% de la población. El análisis de la abundancia relativa a través del año para cuatro macrozonas geográficas reflejaría el movimiento de la especie en las costas de Chile. La zona Norte muestra un peak de abundancia en noviembre con la llegada de individuos, no siendo tan clara su estrategia de retorno. Las zonas Centro-Norte y Centro del país muestran dos peaks en la llegada y partida de individuos, sugiriendo un uso más bien de tránsito. La existencia de un solo peak en el mes de febrero, además de las mayores concentraciones de individuos, indicarían que las zonas Centro-Sur y Sur del país serían potencialmente el destino para gran parte de la población de rayadores. El seguimiento de individuos por medio de radiotelemetría permitió detectar movimiento de individuos entre una red de humedales costeros. Estos desplazamientos ocurrirían frecuentemente a lo largo de toda la temporada y tanto en dirección norte como hacia el sur. Este trabajo presenta información relevante para la evaluación del estado de la especie en Chile, país que potencialmente alberga un porcentaje significativo de la población de la subespecie cinerascens durante el período no reproductivo.

This research presents the benefits of using telemetry in the operations management of a high-production open-pit mine located in the state of Minas Gerais, Brazil. Caterpillar’s telemetry systems called Vital Information Monitoring System (VIMS) were used to monitor trucks via input device signals (sensors and switches), providing action alert messages for the operator through a visor in the cockpit. The processes that will be subject to control are: fuel supply, load imbalance, access conditions, and temperature of the brake cooling system. An interface was developed with the IntelliMine (Modular Mining Systems) fleet management system for mining operations management. A system that identifies the type of problem was implemented, as well as the most efficient means for its resolution and localization in real time.

Resumo: Introdução: A embolia cardíaca por Fibrilhação Auricular (FA) paroxística não diagnosticada é responsável por uma parte substancial dos Acidentes Vasculares Cerebrais (AVC) isquémicos classificados como criptogénicos. As atuais orientações recomendam a monitorização electrocardiográfica nas primeiras 24-48h após a admissão hospitalar. Os autores pretenderam avaliar o número de FA, de novo, identificadas por telemetria em doentes com Acidente Isquémico Transitório (AIT)/AVC isquémico, sem outra etiologia identificada, numa Unidade de AVC, e sua caracterização. Material e Métodos: Foram incluídos os doentes admitidos numa Unidade de AVC tipo C, entre Maio a Dezembro de 2015, e seleccionados aqueles com diagnóstico de AIT/AVC sem etiologia identificada e sem FA conhecida ou previamente documentada, que tiveram registo electrocardiográfico por telemetria durante um período mínimo de 24 horas. A equipa médica foi responsável pela revisão da telemetria para identificação de FA. A análise dos dados foi efectuada com o programa SPSS v23. Resultados: Dos 217 doentes admitidos foram seleccionados 79. A idade média foi de 73,9 anos e distribuição por sexo masculino/feminino de 53,2% e 46,8%, respectivamente. 70 doentes apresentaram AVC isquémico (88,6%) e 9 doentes AIT (11,4%). Dos 79 doentes, 12 (15,2%) apresentaram ritmo de FA no registo por telemetria (FA paroxística: 11; FA persistente: 1) e destes, em 11 (91%) doentes foi alterada estratégia terapêutica com inicio de hipocoagulação. Discussão: O número de FA detectadas na presente série foi sobreponível aos dados aferidos noutros estudos. A telemetria constitui um método importante no diagnóstico de FA em doentes com AVC isquémico que, de outro modo, poderiam ser definidos como criptogénicos. O registo electrocardiográfico por telemetria permite assim assumir mais precocemente uma correcta estratégia terapêutica. Abstract; Introduction: Undetected cardiac embolism by Atrial Fibrillation (AF) is responsible for a substantial number of ischemic strokes classified as cryptogenic. Current guidelines recommend electrocardiographic monitoring for the first 24-48 hours after hospital admission. The authors intended to evaluate the number of new onset AF identified by telemetry in patients with transient ischemic attack (TIA) / ischemic stroke, without other etiology identified, in a stroke unit, and its characterization. Material and Methods: Patients admitted in a type C unite stroke from May to December 2015 were included in the study and selected those diagnosed with TIA / stroke without identified etiology, without know AF or documented on admission of the current hospitalization, and who had electrocardiographic register by telemetry for a minimum period of 24 hours. The medical team was responsible for reviewing telemetry data with the purpose of AF identification. Data analysis was performed with SPSS v23. Results: Of 217 patients admitted in our stroke unit, 79 were selected. The mean age was 73.9 years and 53,2% were male. 70 patients had an ischemic stroke (88.6%) and 9 patients had a TIA (11.4%). Of the 79 patients, in 12 (15.2%) was identified AF rhythm in the telemetry data (paroxysmal AF: 11; persistent AF: 1) and of these, 11 (91%) patients had their therapeutic strategy altered through initiation of anticoagulation therapy. Discussion: The number of AF detected in this series was similar to the data from other studies. Telemetry is an important exam in the diagnosis of AF in patients with ischemic stroke, that otherwise, could be defined as cryptogenic. The electrocardiographic recording by telemetry permits an earlier and correct therapeutic approach.

La variabilidad espacio-temporal del Material Particulado en Suspensión (MPS) en el Río de la Plata (RdlP) fue analizada para el periodo 2002-2014 a partir de datos Aqua-MODIS (Moderate Resolution Imaging Spectroradiometer), y posteriormente se explicó su variabilidad en términos de sus principales tributarios. La media mensual de la concentración del MPS mostró, un máximo a partir de fines del verano hasta mediados de otoño, y un mínimo, a partir de mediados del invierno hasta comienzos del verano. El río Bermejo (RBe), es el tributario que más sedimentos en suspensión transporta, situación que se reflejó en la relación significativa hallada entre la concentración media mensual del MPS y la descarga mensual promedio del RBe. La variación estacional del MPS, tuvo valores máximos durante el otoño y el verano, y valores mínimos en el invierno y la primavera, reflejando así el patrón mensual de descarga del RBe con uno y dos meses de retraso. La variación espacial evidenció tres regiones: interior, central y exterior. Por su parte, la variabilidad anual denotó una marcada estacionalidad en el patrón de cobertura espacial de las aguas con mayor concentración de MPS. La distribución de las anomalías estuvo relacionada con la influencia de la descarga de los ríos, lo que puso de manifiesto que el patrón temporal no está vinculado con el ciclo ENSO (El Niño – Sourthen Oscillation). Estos resultados nos permitieron denotar la importancia del RBe (no ENSO dependiente) para explicar el patrón de anomalías del MPS observado en el RdlP.

In precision agriculture, the use of Remote Piloted Aircraft Systems (RPAS) has increased significantly, due to the advantage of obtaining crop information from different sensors. This has generated the need for aircraft capable of performing autonomous and georeferenced flights to obtain the desired information with precision. With this purpose, a quadcopter type RPAS was designed and built with a system that allows autonomous and stable flights to obtain georeferenced images, through the instrumentation of a RGB sensor (Sony IMX117) and a GPS. For the design of the RPAS, weight, flight time, flight height, payload and control system were considered as requirements. With the design parameters, a RPAS was built, equipped with a Pixhawk controller with GPS, 1400kv race star engines, eight-inch propellers (8045) and 30A ESC. A RPAS was designed and built, weighing less than 2 kg and the RPAS was drawn in 3D, using a "CAD" system, which allowed the center of mass and stresses caused by the weight of the vehicle to be modeled, obtaining a safety factor of 7.95 with the Von Mises Stress.

Migration is a period of high activity and exposure during which risks and energetic demand on individuals may be greater than during nonmigratory periods. Stopover locations can help mitigate these threats by providing supplemental energy en route to the animal's end destination. Effective conservation of migratory species therefore requires an understanding of use of space that provides resources to migratory animals at stopover sites. We conducted a radio-telemetry study of a short-distance migrant, the American Woodcock (Scolopax minor), at an important stopover site, the Cape May Peninsula, New Jersey. Our objectives were to describe land-cover types used by American Woodcock and evaluate home range habitat selection for individuals that stopover during fall migration and those that choose to overwinter. We radio-marked 271 individuals and collected 1,949 locations from these birds (0–21 points individual–1) over 4 yr (2010 to 2013) to inform resource selection functions of land-cover types and other landscape characteristics by this species. We evaluated these relationships at multiple spatial extents for (1) birds known to have ultimately left the peninsula (presumed migrants), and (2) birds known to have remained on the peninsula into the winter (presumed winter residents). We found that migrants selected deciduous wetland forest, agriculture, mixed shrub, coniferous wetland forest, and coniferous shrub, while wintering residents selected deciduous wetland forest, coniferous shrub, and deciduous shrub. We used these results to develop predictive models of potential habitat: 7.80% of the peninsula was predicted to be potential stopover habitat for American Woodcock (95% classification accuracy) and 4.96% of the peninsula was predicted to be potential wintering habitat (85% classification accuracy). Our study is the first to report habitat relationships for migratory American Woodcock in the coastal U.S. and provides important spatial tools for local and regional managers to support migratory and winter resident woodcock populations into the future. LAY SUMMARY Stopover sites provide habitat for migratory animals to rest and refuel before continuing migration, making these areas important for species' conservation. We used radio-telemetry to assess American Woodcock stopover and wintering habitat selection on the Cape May Peninsula, New Jersey. Short-term migrants used a greater variety of land-covers than winter residents, although both selected deciduous wetland forest and sites in close proximity to fields. Less than 10% of the Cape May Peninsula provides stopover or wintering habitat for American Woodcock, highlighting the importance of conserving these important but potentially limited resources.

The giant armadillo (Priodontes maximus) is the largest living armadillo. This naturally rare and poorly known species is endemic to South America and classified as "Vulnerable" by the IUCN. Here we explored aspects of the spatial ecology of P. maximus in Midwestern Brazil to gain insights on its ecology and biology to support conservation efforts. In 8 years, we identified 50 individuals of P. maximus and monitored 23 of them using telemetry methods. To characterize site fidelity and home range, we fitted individual continuous-time movement models and estimated Autocorrelated Kernel Density Estimates. We built a Structural Equation Model to evaluate how home-range area and daily displacement are related to each other, to sampling effort, and to individual characteristics. We estimated home-range overlap between pairs of different sexes using a bias-corrected Bhattacharyya coefficient. Finally, we formulated a canonical density estimation formula to characterize minimum population density. We gathered a total of 12,168 locations of P. maximus. The best-fitted movement models indicated site fidelity for all individuals and a median adult home-range area of 2,518 ha. Median adult daily displacement was 1,651 m. Home-range area scales positively with daily displacement and daily displacement scales positively with body mass. Median home-range overlap between pairs was low (4%) and adult females presented exclusive home ranges among themselves. Median minimum density was 7.65 individuals per 100 km2 (CI = 5.68–10.19 ind/100 km2). Our results are congruent with characterizing P. maximus as a generally asocial species, most likely promiscuous/polygynous, that establishes large, long-term home ranges, which grants the population a naturally low density. Spatial patterns and biological characteristics obtained in this study can be used to guide future conservation strategies for P. maximus in the Pantanal wetlands and elsewhere.

Telemetry monitoring using different technologies has been used for Red Kite, Milvus milvus, study and conservation since 2000. The monitoring of a significant number of individuals has helped to determine home ranges and areas of high use, casualty localisation and mortality causes. A progressive range expansion in Mallorca has been observed from the area that the population had been confined to at the end of the nineties, presently occupying those areas of greater environmental quality. Conversely, casualty localisation obtained by telemetry monitoring has identified poisoning as the main mortality factor and the fundamental cause of having placed the species on the verge of extinction. Therefore, the monitoring of birds in Mallorca has contributed in asserting the territorial use of this species and determining the most important areas for its survival, as well as facilitating the implementation of necessary mitigation actions and assist in the recovery of the population.
