Today, communication between objects, machines, objects to machines and to humans is possible due to the Internet of Things (IoT). However, their applicability is restricted mostly to areas that are inhabited by humans. Monitoring and tracking in wilderness areas is still a challenging task to date, if not impossible. To bridge this gap, IoT networks are instrumented with Wireless Sensor Networks that are capable of providing remote services through multi-hop communication paradigm. Since these networks are deployed in deserted places, it becomes very crucial to protect the privacy of the location information of critical events or sources that these networks are monitoring. To this end, we propose a new random-walk based routing protocol namely BLS (Backward walk, L-walk, Shortest path walk) to protect the location of critical sources/events. The aim is to break the correlations between the network traffic and render the traffic-analysis efforts of the attacker, in locating the source of information, useless. In addition, we also evaluate the performance of the proposed technique by comparing it with the existing techniques using different privacy metrics such as safety period, entropy and capture ratio. Through this research work, we observed that the performance of source location privacy (SLP) preservation techniques is giving differing results for different privacy metrics. Although the proposed solution outperforms in terms of entropy metric by 104.59-folds improvements compared to Forward Random Walk technique, its performance in terms of safety period and capture ratio metrics are very poor with an improvement of just 0.65-folds and 0.1-fold respectively. Therefore, there is a dire need to come up with a right choice of metric for SLP preservation techniques. [ABSTRACT FROM AUTHOR]

The jaguar is listed as endangered in Mexico. However, population estimates and conservation initiatives have relied on data obtained from Protected Areas (PA) covered by humid tropical forests of southern Mexico. In this context, the objectives were: 1) to estimate jaguar density for the last wilderness ecoregion of central-western Mexico, 2) quantify the capture rate of potential prey of jaguar, 3) evaluate the percentage of native vegetation cover in the Effective Sampling Area (ESA), and 4) review the density estimates of jaguars in Mexico. Jaguar density was evaluated in an ESA of 156 km2, using 'Capture–Recapture' (C-R) and 'Spatially Explicit Capture–Recapture' (SECR) models. We obtained 28 photographic captures of two females, in which models averaged a density of 1.01 ± 0.41 ind/100 km2. The mid and large size-mammal community included 14 species with forested landscape and vegetation measured at 90%. The scientific literature includes 30 jaguar density estimates in Mexico, with 22 (85%) inside Protected Areas. Average density among all estimates in México is 2.85 ± 1.82 STD. For the first time, our density estimates provide reliable population-level data for one key region for jaguar conservation efforts in the northern hemisphere. As low-density estimates were obtained, this population is highly vulnerable, deserving priority attention by conservation strategies at a national level. RESUMEN El jaguar está en peligro de extinción en México. Sin embargo, las estimaciones de sus poblaciones y las iniciativas de conservación se han basado en datos obtenidos en Áreas Protegidas (AP) cubiertas por bosques tropicales húmedos del sur de México. En este contexto, los objetivos fueron: 1) estimar la densidad de jaguares para la última ecorregión silvestre del centro-oeste de México, 2) cuantificar la tasa de captura de presas potenciales del jaguar, 3) evaluar el porcentaje de cobertura de vegetación nativa en el Área Efectiva de Muestreo (ESA en ingles) y 4) revisar las estimaciones de densidad de jaguares en México. La densidad del jaguar se evaluó en una ESA de 156 km2, utilizando modelos de "Captura-Recaptura" (C-R) y "Captura-Recaptura Espacialmente Explícitos" (SECR en ingles). Obtuvimos 28 capturas fotográfícas de dos hembras, en las cuales los modelos promediaron una densidad de 1.01 ± 0.41 ind/100 km2. La comunidad de mamíferos de tamaño mediano y grande incluyó 14 especies con un paisaje boscoso y una cobertura vegetal de 90%. La literatura científica incluye 30 estimaciones de densidad de jaguares en México, 22 (85%) dentro de Áreas Protegidas. La densidad promedio entre todas las estimaciones en México es de 2.85 ± 1.82 ETS. Por primera vez, nuestras estimaciones de densidad proporcionan datos confiables a nivel de población para una región clave en los esfuerzos de conservación del jaguar en el hemisferio norte. Debido a la baja densidad reportada en este estudio, esta población es altamente vulnerable y merece una atención prioritaria por parte de las estrategias de conservación a nivel nacional.

Hiking and trail running are a source of microplastic (MP) pollution on recreational trails in wilderness and conservation areas; however, the fate of MPs deposited on trails is poorly understood as MP mobility on such surfaces has not yet been examined. In this study, we simulated heavy rainfall (100 mm/h) on trail surfaces with existing MP pollution (in situ MPs) and spiked with 99 ± 2 rubber MPs (100–940 μm). Runoff was collected for 15 min and spiked and in situ MPs were quantified. Hydrological, erosional and microplastic responses were evaluated in relation to slope, bulk density, soil moisture and surface condition indicators, including amounts and types of surface cover and soil physical attributes. The MPs were largely immobile, with 85–100% of spiked MPs retained on trail surfaces. In situ MPs were detected in the trail runoff, with the majority being polyurethane, polypropylene and polyester. Microplastic movement was primarily influenced by hydrological effects, and analysis indicated the main explanatory variable was total runoff volume, followed by soil slaking. Trail sections with at least 15% herbaceous cover or a layer of loose alluvium had higher MP retention. Areas of resource accrual may be preferentially enriched, suggesting MPs from outdoor recreation may be concentrated on and adjacent to recreational trails. Microplastics deposited on trails may have long term implications for biodiversity and ecosystem functioning in wilderness and conservation areas, particularly around the trail corridor.

Fitting mathematical models to describe the influence of topographic factors and coexisting plants on wild jujube distribution was performed to provide a scientific basis for wild jujube forestation. Investigation quadrats, with straight-line distances between adjacent quadrats of longer than 100 m, were set up in areas of wilderness or low human disturbance, which were rich in wild plant species. Data concerning altitude, slope aspect, slope position and slope degree of each investigation quadrat, as well as the type and number of coexisting wild plants, were collected. Based on this, correlations with the average number, occurrence probability and density of wild jujube and these variables were analyzed, and data models were established. Results of analyses show that topographic factors such as altitude, aspect, gradient, slope and position, play an important role in the distribution of wild jujube; and that Vitex negundo var. heterophylla (Franch.) Rehd. coexistence is related to wild jujube distribution. Both average number and occurrence probability of wild jujube conform to a GaussAmp model with altitude. The highest average number was recorded at 581.24 ± 13.78 m above sea level, and the highest occurrence probability at 462.53 ± 36.67 m above sea level. Average number and occurrence probability of wild jujube were fit to a linear model with slope aspect—with mathematical slope 0.49 ± 0.16—indicating that wild jujube is a light-loving and drought-tolerant plant. Average number and density of wild jujubes were fit to GaussAmp models with slope position. The highest average number and the highest density of wild jujube appears on the upper part of the middle slope. Wild jujube occurrence probability was correlated to slope degree in a quadratic equation model. With an increase in slope degree, the distribution number of wild jujube increased sharply. The survey data of slope position and slope degree further reinforced the observed drought-resistance qualities of wild jujube. Average number and density of wild jujubes were correlated to the number of Vitex negundo var. heterophylla by quadratic equation models. No other plants investigated conformed to a statistically significant relationship with wild jujube distribution. Our results suggest altitude, slope aspect, slope position and slope degree play an important role in wild jujube distribution, and that Vitex negundo var. heterophylla is an important coexistent plant species for wild jujube.

This article examines the way Margaret Atwood's short story 'Death by Landscape' (1991) engages with the representational strategies of Canada's celebrated Group of Seven artists. I situate my reading of Atwood's work first within aesthetics, focusing on her subtle problematization of the masculine ideology and wilderness aesthetic of the Group of Seven. I argue that Atwood unsettles the dominant, virulently male tradition of representation of the wilderness by uncovering an alternative female narrative through an ekphrastic engagement with the paintings. By doing so she not only dismantles the concept of wilderness both as a physical space that women have limited access to and as an imaginary construct; but at the same time she also reconfigures the structure and the content of wilderness stories, and in fact the concept of wilderness itself. Atwood offers a counter-discursive revision of the male adventure and maturation story by deconstructing and restructuring traditional narrative practices to render the female experience visible. This article hopes to show that Atwood expands the possibilities of the adventure story and wilderness writing and creates room for a female version of the maturation story with a fundamentally different aesthetic.

The growing popularity of nature-based tourism means that the tourism industry is increasingly utilizing wilderness areas to provide visitor experiences. However, tourism activities negatively impact wilderness quality. Tourism service providers play an important role in shaping these impacts. Therefore, this study investigates their preferences regarding wilderness use and development. It focuses on the Icelandic Central Highlands, which contain some of Europe's largest wildernesses and are an important venue for tourism. The relationship between participants' preferences and environmental attitudes is also investigated, providing insights into the reasoning behind these preferences. For this study an online questionnaire was distributed among day tour providers and travel agencies operating in Iceland. The results revealed that the attitudes of over 87% of the participants were pro-environmental. Accordingly, most tourism service providers preferred basic tourism infrastructure in the Central Highlands, and they did not support further energy or road developments. However, their attitudes toward the Central Highlands National Park proposal were divergent despite the positive relationship with environmental attitudes. Concerns about regulations and access restrictions to the area played an important role in shaping the attitudes toward the national park proposal, demonstrating the importance of considering tourism stakeholders' interests for ensuring their support for wilderness conservation.

Much of Europe's remaining wilderness areas are found in Iceland, yet few are formally protected despite ongoing threats from renewable energy exploitation and 4 × 4 usage. Robust and repeatable approaches are required to map wilderness landscape qualities in support of developing policy on designations that meet international standards. We present an approach to mapping wilderness that is based on internationally recognised methods and customised to suit the unique nature of Icelandic landscapes. We use spatially explicit models of wilderness attributes that measure human impact from vehicular access, land use and visible human features rather than relying on proxy measures such as buffer zones. Seventeen wilderness areas are identified across the Central Highlands and surrounding areas, totalling some 28,470 km2. These are compared to existing mapping projects. The character of these areas is described using additional spatial data models on openness, ruggedness and accessibility from settlements, together with information on mobile phone coverage and grazing patterns. This is the most detailed mapping of wilderness in Iceland to date and an important step towards the formal definition of boundaries of wilderness areas meeting IUCN Category 1b and Wild Europe Working Definition in Iceland.

Air tour management plans for U.S. national park units are developed by the Federal Aviation Administration (FAA) and the National Park Service (NPS). The FAA recommends pilots fly higher than 2,000 feet above ground level (AGL) over parks, wildlife refuges, and areas with wilderness characteristics. Management of air tours is important for mitigating visual and noise impacts. Understanding air tour travel patterns has been problematic because objective location data have been difficult to obtain. A newer technology, Automatic Dependent Surveillance–Broadcast (ADS–B), can be used to accurately track overflights. Prior ADS–B studies of air tours conducted limited analysis with respect to altitude characteristics. Thus, the purpose of this study was to determine how overflights spatially vary across altitudes and determine altitude trends for primary flight corridors. Results suggest overflights trend along the east side of the park and 74.59 percent of waypoints within a 0.5-mile buffer around the park boundary had altitudes less than 2,000 feet above ground level (AGL). Results revealed that as altitude increased, overflight density decreased. Using hot spot clustering analysis, overflight lateral pattern differences were determined for altitudes lower than 2,000 feet AGL compared to altitudes higher than 2,000 feet AGL. This study also identified one primary flight corridor with average altitudes mostly below 2,000 feet AGL. Managers can use these results to inform the development of air tour management plans and monitor compliance. [ABSTRACT FROM AUTHOR]

The natural heritage and ecological processes of protected wilderness areas (ASP) are constantly threatened by a variety of factors, including wildfires. This study seeks to evaluate the impacts of large wildfires (IFM, = 200 ha) in the ASPs of central Chile over the last 20 years (2000 - 2020), by identifying and characterizing the affected areas as well as the damages caused. To identify the affected sectors, burned areas were mapped using historical records along with remote sensing tools. The maps of burned areas allowed for the identification of 35 large wildfires that have impacted the ASPs of central Chile, including 17 SNASPE units and Nature Sanctuaries. The origin of most wildfires was located outside of the administrative limits of the ASPs and began in native forests and plantations. Regarding the main damages caused, 16 ecosystem types were affected by IFMs, 12 of which were under a significant level of risk. Additionally, considering the effects on water quality, an average of 21.2 ha of affected riparian vegetation was recorded per year, while 15 units recorded damage to soil conservation. Regarding CO2 emissions, an average of 10,389 tCO2 per year were released into the atmosphere. Finally, the results led to four different guideline recommendations for managing and preserving these areas, which focused on reducing occurrences, preventing large wildfires, and post-fire management in the ASPs.

The creation account of Gen 1:1–2:3 is only one of several accounts featured in the Old Testament/Hebrew Bible. The one account that most closely matches its cosmic orientation is the poetic description of creation given in Job 38–41. Nevertheless, both accounts are worlds apart regarding how they describe creation and what they find most important about creation. Their theological and literary differences make for a lively intertextual conversation, as entertained in the interpreter's imagination. Let the dialogue begin. [ABSTRACT FROM AUTHOR]

The article focuses on understanding of "trans" through the photography of Gohar Dashti, who was born in Iran on the border with Iraq and who grew up during the Iran-Iraq War. It mentions Dashti challenges the idea of national borders and the very concept of borders and photographs combine staged theatricality with the seeming simplicity of family snapshots. It also mentions series of imposing panels covered in images of American wilderness.

This paper is a photographic summary of a scientific and touristic expedition carried out in June 2022 in the Triglav National Park, located in the northwestern of Slovenia. The Flora and fauna of the Park are very rich and diverse, and also has a huge number of rivers, streams, and crystalline lakes, emerald-blue in color and connected by a series of cascades and waterfalls, embedded in a network of mountains in the Julian Alps. The photos show park structures and wilderness areas, with spacious forest complexes, lakes, small streams, and waterfalls extending, besides geological formations, plants, and animal species.

Protected areas are needed to conserve nature and biodiversity worldwide. The province of Québec (Canada) recently established a large wilderness area affording significant habitat protection for boreal woodland caribou (Rangifer tarandus caribou), a wide‐ranging species at risk. We describe a decision support framework combining ecological modeling with socioeconomic constraints that ultimately led to the creation of this protected area. Multiple criteria were used to identify candidate protected areas for boreal caribou. These had to be large in size (>10,000 km2) and located in regions where available high‐quality habitat was threatened by development pressures. Candidate areas also had to contribute substantively to the maintenance of functional habitat connectivity, be exempt from major industrial developments and recent fires, and required evidence of recent use by caribou. Five candidate protected areas emerged from this exercise. Key regional stakeholders were consulted, thereby strengthening advocacy for land designation, and boundaries were refined through their input, which helped further reduce socioeconomic conflicts. This process involved difficult compromises, but eventually led to the legal designation on March 4, 2021 of a new protected area for boreal caribou known as the Caribous‐Forestiers‐de‐Manouane‐Manicouagan. We show how our science‐informed decision support framework was instrumental in the success of this endeavor, and describe the obstacles overcame in the process, so that other jurisdictions may draw from this experience in their efforts to achieve similar conservation goals.

Highlights: The peat age was late Holocene, and less than 1900 years old. The peat contained no charcoal, probably due to the lack of woody cover at the site for 1900 years. Depth profiles of clay and nutrients (P, K, Ca, Mg) revealed an increase in atmospheric inputs over time, while nitrogen is homogeneously sequestrated in depth. The dominant metallic trace elements (MTE) were cadmium, which peaked during the Roman epoch, then lead and mercury concentrated during the modern period, but decreasing onwards. Peat geochemistry is strongly influenced by local and regional human activities, revealing a peat modified by social imprints. Sedimentological and biogeochemical measurements were conducted on minerotrophic peat in a wilderness area on a granitic plateau to reconstruct the local ecosystem's history and clarify the peat's response to local and global changes. The peat is less than 1900 years old. Its clay and iron (Fe) concentration profiles revealed an increasing atmospheric influx over time, whereas the levels of its nutrients (P, K, Ca, Mg) have increased since the 19th century. Additionally, changes in the relative abundance of amorphous aluminium indicated a gradual decrease in soil weathering. The dominant metallic trace elements were cadmium during the Roman epoch and early Middle Ages, then lead and mercury during the modern and the industrial eras. Unexpectedly, the peat proved to be sub-modern and lacks wildfire proxies, probably indicating an absence of nearby woodlands over the last 1900 years. Its concentrations of Ca and Mg indicate that airborne transport of particles released by soil erosion in lowland agricultural plains has strongly affected the peat's composition since the 18th–19th century. The site has also been heavily influenced by metallic contamination due to regional metallurgy and agriculture, producing a peat that has been modified by social imprints over several centuries.

• The wilderness was identified using Boolean overlay and multi-criteria evaluation methods. • The connectivity of the wilderness network was evaluated based on the identified wilderness as ecological sources. • Wilderness network can strengthen the network of nature reserves. • Constructing a wilderness network helps to select rewilding areas. • Enhancing the stability of the wilderness network is a strategy to address landscape fragmentation. Wilderness areas provide important ecosystem services for human being, and as crucial habitats for diverse species. Human activities have led to the fragmentation of wilderness landscapes, posing a significant challenge to biodiversity conservation. Identifying wilderness areas and assessing their network connectivity is fundamental for developing strategies to address this fragmentation. This study used Zhejiang Province, China, which is in the process of rapid urbanization as a case study. We identified the spatial distribution of wilderness by combing the index system and its weights of wilderness identification, using Boolean superposition analysis and the multi-criteria evaluation method, and tested the ecological sensitivity. Additionally, the connectivity of the wilderness network was assessed using the wilderness identification results in Zhejiang Province as ecological sources. The results indicate that: (1) 50% of Zhejiang Province still maintains relatively good wilderness integrity. (2) The wilderness network can cover 82% of highly fragmented habitats and currently unallocated potential natural reserves. (3) In areas not designated as nature reserves but experiencing frequent species movement as well as in identified wilderness regions, robust wilderness networks may play a crucial role in biodiversity conservation. The findings provide quantitative evidence for biodiversity-oriented wilderness network protection and landscape fragmentation management. The results also aid in selecting specific areas for rewilding and ecological restoration, thereby enhancing the overall robustness of the wilderness network. [ABSTRACT FROM AUTHOR]

• Priority areas for process-oriented conservation are mapped for the Alpine Space region. • We compare an ecoregional with a conventional approach to identify priority areas. • Priority areas are identified based on the wilderness quality index. • Ecoregion-based priority areas cover greater ecosystem- and species-level diversity. • Both wilderness protection and rewilding are needed across different ecoregions. Amidst the global decline in biodiversity, there are growing calls for more ambitious conservation targets and practices, including a renewed focus on protecting and restoring natural processes. However, little is known about suitable areas for process-oriented conservation and its different strategies. In this paper, we identify priority areas for process-oriented conservation following an ecoregion-based approach. Using the Alpine Space programme area as a pilot study area, a Wilderness Quality Index is calculated and mapped based on spatial indicators reflecting variations in naturalness, human impact, remoteness, and ruggedness. To identify priority areas for process-oriented conservation, the 10% of areas with the highest wilderness quality are identified for each ecoregion ('ecoregional approach') and compared with the identification of the 10% wildest areas of the entire study area ('conventional approach'). The results show significant differences in priority areas between the two approaches, with those identified by the ecoregional approach being of lower wilderness quality, more dispersed across the study region and different elevation classes, and smaller in size. The ecoregional approach results in a greater coverage of ecosystem- and species-level diversity, yet it highlights a greater need for complementing the protection of wilderness in less modified regions with rewilding initiatives and the expansion of the protected area network in ecoregions with significant human activity. Based on these findings, we discuss the potential and challenges that an ecoregion-based identification of priority areas brings for biodiversity conservation, protection and restoration practice, and local communities. The ecoregion-based approach and the findings of this study can inform initiatives under the EU Biodiversity Strategy to 2030, in particular the target to 'strictly protect' 10% of the EU's land and sea.
