- Abstract
Animal community responses to extreme climate events can be predicted from the functional traits represented within communities. However, it is unclear whether geographic variation in the response of functional community structure to climate change is primarily driven by physiological matching to local conditions (local adaptation hypothesis) or by differences between species pools in functional redundancy (insurance hypothesis). We conducted a coordinated experiment to understand how aquatic invertebrate traits mediate the responses of multitrophic communities to changes in the quantity and evenness of rainfall in 180 natural freshwater microcosms (tank bromeliads) distributed across six sites from 18 degrees N in the Caribbean to 29 degrees S in South America. At each site, we manipulated the mean and dispersion of the daily amount of rainfall that entered tank bromeliads over a 2-month period. Manipulations covered a response surface representing 50% to 200% of the dispersion of daily rainfall crossed with 10% to 300% of the mean amounts of rainfall. The response of functional community structure to precipitation regimes differed across sites. These geographic differences were not consistent with the local adaptation hypothesis, as responses did not correlate with the current amplitude in precipitation. Geographic differences in community responses were consistent with the insurance hypothesis: sites with the lowest functional redundancy in their species pools had the strongest response to a gradient in hydrological variability induced by uneven precipitation. In such sites, an increase in the hydrologic variability induced a shift from communities with both pelagic and benthic traits using both green and brown energy channels to strictly benthic, brown energy communities. Our results predict uneven impacts of precipitation change on community structure and energy channels within communities across Neotropical regions. This geographic variation is due more to dif

Bromeliads interact with thousands of plants, animals and microorganisms. Some species are considered keystone species for providing shelter and protection to many species from vertebrates to microbes. Aechmea distichantha is a tank bromeliad distributed in the mid-latitudes of South America, known to interact with a wide variety of animal species. Studies aiming to provide inventories of the whole fauna associated are needed. An exhaustive academic review of interactions of this plant species with fauna was carried out including scientific articles, books, book chapters, theses, and reports published in different languages, where interactions between A. distichantha and an animal species were reported. These interactions were classified depending on the use that animals made of the plant and on the part of the plant involved. Since 1960, 347 animal morphospecies, involved in 495 interactions with A. distichantha have been documented. The plant was principally used as habitat or shelter, secondly used for food supply (herbivores, detritivores and predators), and finally for nesting. Morphospecies were mainly associated with the foliage and the phytotelmata, but also with the inflorescence, the inter-ramet space and the stolon. Invertebrates: Arachnids, mainly took refuge or shelter in the plant, and also found their preys. Insects, the most important class, took refuge on or inhabited in the plant and to a lesser extent used the plant for food supply. Vertebrates: amphibians, tortoises and reptiles exclusively used the plant for shelter, while birds and mammals mainly established feeding links. This is the first proposal tending to collect the whole set of animals interacting with this species. Aechmea distichantha is a keystone species that establish diverse, numerous direct and empirically detected interactions with fauna, and plays an important role in providing ecosystem services to humans.

- Abstract
The eastern Formosa forests of Argentina, belonging to Eastern Chaco District, are distributed following a gradient from the watercourse levee where the ‘Bosque Ribereño’ is placed, through an intermediate zone where the so-called ‘Bosque Transicional’ develops, up to the topographically lower zone where the ‘Monte Fuerte’ forest is located. It has been postulated that the distribution of woody species amongst these three types of forests could be explained by their ability to survive to different stress conditions of water availability. In such context, it is proposed that, to the seedling status, that capacity could differ between species belonging to these forests, related to the topographic height of them. The tolerance to ‘restricted watering’ and ‘flooding’ controlled conditions in seedlings of eight selected woody species, (Peltophorum dubium, Enterolobium contortisiliquum, Gleditsia amorphoides, Microlobius foetidus, Diplokeleba floribunda, Caesalpinia paraguariensis, Prosopis nigra and Schinopsis balansae) belonging to the three forest types, was experimentally evaluated in this contribution. The results showed that the seedlings of all species were less tolerant to flooding prolonged conditions than to the ‘drought’ (restricted watering) level applied. None of them was affected in terms of growth under the ‘restricted watering’ treatment. In this way, the hypothesis could not be validated, nevertheless it is considered that such answer could be related to the fact these woody species usually thrive in the Seasonally Dry Tropical Forests domain., Los bosques ubicados en el sector este de la provincia de Formosa (Argentina), pertenecientes al Distrito del Chaco Oriental, se distribuyen desde el borde del albardón del curso de agua, donde se encuentra el llamado ‘Bosque Ribereño’, atravesando zonas intermedias en que se desarrolla el ‘Bosque Transicional’, hasta la parte topográficamente más baja donde se encuentra el denominado ‘Monte Fuerte’. Se considera que la distribución de especies en los tres tipos de bosques podría estar explicada por la capacidad de las plantas para sobrevivir a diferentes condiciones de disponibilidad hídrica; y, en tal contexto, se propone que, al estado de plántula, dicha capacidad podría diferir entre especies pertenecientes a esos bosques, y estar en relación a la altura topográfica de los mismos. En este trabajo se evaluó experimentalmente la tolerancia de plántulas de ocho especies leñosas pertenecientes a dichos bosques (Peltophorum dubium, Enterolobium contortisiliquum, Gleditsia amorphoides, Microlobius foetidus, Diplokeleba floribunda, Caesalpinia paraguariensis, Prosopis nigra y Schinopsis balansae) a condiciones controladas de irrigación (anoxia y restricción hídrica) durante 110 días. Se encontró que las plántulas de todas las especies resultaron menos tolerantes a las condiciones de anoxia prolongada que al nivel de restricción hídrica implementado. Ninguna de ellas vio afectado su crecimiento en el tratamiento ‘restricción hídrica’. De esta manera no pudo validarse la hipótesis planteada, pero se considera que tal respuesta podría relacionarse con la pertenencia de varias de las especies estudiadas a bosques que, por su composición florística y distribución geográfica, corresponden al dominio de los Bosques Secos Estacionales Neotropicales.

- Abstract
In this work, we present a new record of piche llorón Chaetophractus vellerosus (Cingulata, Dasypodidae) for the south of the Santa Fe province. At present, the existing records for this type of armadillo included a fossil record and three current records for the north of the province, with no data for the southern region. In June 2018, using Tomahawk-type traps, two specimens (male and female) were captured in two field plots of the Estancia 'Santa Marta', located about 3 km south of Christophersen. There are two disjunct populations in Argentina, one located to the north-center of the country and another to the east of the Pampas region. This is the first record of this species for the Pampas region of the Santa Fe. Although it matches with the predictions of the proposed distribution area, could slightly extend the distribution of the population of the north-center. The few records of this species for the Santa Fe province show the urgent needs for fieldworks that study the local fauna in a province where more than 80% of natural environments have been lost and transformed into agricultural fields. En este trabajo se presenta el primer registro de piche llorón Chaetophractus vellerosus (Cingulata,Dasypodidae) para el sur de la provincia de Santa Fe. Hasta el momento, los registros existentes para esta especie de armadillo comprendían un registro fósil y tres actuales para el norte de la provincia, noexistiendo datos para la región sur. En junio de 2018, utilizando trampas tipo Tomahawk, se lograroncapturar dos ejemplares (macho y hembra) de piche llorón en dos lotes de la Estancia ‘Santa Marta’,ubicada a unos 3 km al sur de la localidad de Christophersen. Existiendo dos poblaciones disyuntas paraArgentina, una ubicada al norte-centro del país y la otra al este de la Región Pampeana, este nuevoregistro constituye el primero para la Región Pampeana de la provincia de Santa Fe. Si bien coincide conlas predicciones del área de distribución ya propuesta, extendería levemente la distribución de la población del norte-centro. La escasez de registros de esta especie para la provincia, dan cuenta de lanecesidad de trabajos de campo que estudien la fauna local en una provincia donde más del 80% de losambientes naturales se han perdido y transformado en agrícolas.

Las epífitas aportan una gran diversidad específica y brindan numerosos servicios ecosistémicos en los bosques. En el Chaco Húmedo, los estudios sobre epífitas son muy escasos, por lo cual se realizó una descripción de la comunidad de epífitas vasculares de cuatro especies arbóreas deciduas representativas de un quebrachal de la Cuña Boscosa Santafesina. Dos especies pertenecen al estrato superior (Schinopsis balansae y Sideroxylon obtusifolium) y dos al inferior (Prosopis spp. y Acacia praecox). En invierno se seleccionaron al azar ocho individuos de cada especie y cada uno fue dividido en cuatro zonas (Zona I-II: tronco principal; Zona III: bases de las ramas; Zona IV: parte media de las ramas; Zona V: ramas más finas). En cada zona se contaron e identificaron a nivel de especie todas las epífitas vasculares. En la Zona V se diferenciaron ramas vivas y secas. Los datos se analizaron estadísticamente con modelos lineales generalizados mixtos y análisis multivariados. Se registraron 14 especies (nueve holoepífitas, dos facultativas y tres accidentales) de cuatro familias (Bromeliaceae, Cactaceae, Polypodiaceae y Anacardiaceae). La familia Bromeliaceae fue la más rica, con siete especies del género Tillandsia y Aechmea distichantha. La especie más abundante fue Tillandsia recurvata. Prosopis spp. tuvo la mayor abundancia de epífitas y S. obtusifolium la mayor riqueza. La Zona V tuvo mayor abundancia y riqueza de epífitas en promedio que las otras zonas. Se observaron diferencias cuantitativas entre forófitos en la composición de especies: A. distichantha y T. loliacea estuvieron asociadas positivamente con S. obtusifolium. Prosopis spp. tuvo mayor abundancia y riqueza de epífitas en ramas secas, y los forófitos del estrato superior, en ramas vivas. Las diferencias en abundancia, riqueza, composición específica y distribución vertical de epifitas entre forófitos podrían atribuirse a sus características morfológicas y a la variedad de microhábitats en el tronco y las ramas. In numerous forests, the vascular epiphytes contribute substantially to species diversity. Studies about vascular epiphytes in the Wet Chaco region are very scarce. We carried out a description of the epiphyte community in four deciduous tree species, representative of a quebrachal of the Cuña Boscosa Santafesina: two of them from the upper stratum (Schinopsis balansae and Sideroxylon obtusifolium) and two from the lower one (Acacia praecox and Prosopis spp.). Eight individuals of each tree species were selected, and each individual was divided in four zones (Zone I-II: main trunk; Zone III: basal branches; Zone IV: middle branches; Zone V: thinnest branches). For each zone, all the vascular epiphytes were counted and identified at species level. In Zone V, living and dead branches were differentiated. Data were analyzed with general linear mixed models and multivariate analysis. Fourteen species of vascular epiphytes were recorded (nine holoepiphytes, two facultative and three accidental epiphytic species) of four families (Bromeliaceae, Cactaceae, Polypodiaceae and Anacardiaceae). The richest family was Bromeliaceae, with seven species of the genus Tillandsia and Aechmea distichantha. The most abundant species was Tillandsia recurvata. Prosopis spp. had the highest abundance of epiphytes and S. obtusifolium the highest richness. Zone V had the highest average abundance and richness of vascular epiphytes. There were quantitative differences in species composition between phorophytes: A. distichantha and T. loliacea were positively associated with S. obtusifolium. Prosopis spp. had the highest abundance and richness in dead branches and the phorophytes of the upper stratum in the living ones. The differences in abundance, richness, specific composition and vertical distribution of vascular epiphytes between phorophytes could be attributed to their morphological characteristics and the microhabitats conditions in the trunk and branches.

INVERTEBRATE communities ,SOCIAL influence ,CLIMATE change ,SPECIES distribution ,CONTRAST effect - Abstract
Functional traits determine an organism's performance in a given environment and as such determine which organisms will be found where. Species respond to local conditions, but also to larger scale gradients, such as climate. Trait ecology links these responses of species to community composition and species distributions. Yet, we often do not know which environmental gradients are most important in determining community trait composition at either local or biogeographical scales, or their interaction. Here we quantify the relative contribution of local and climatic conditions to the structure and composition of functional traits found within bromeliad invertebrate communities. We conclude that climate explains more variation in invertebrate trait composition within bromeliads than does local conditions. Importantly, climate mediated the response of traits to local conditions; for example, invertebrates with benthic life‐history traits increased with bromeliad water volume only under certain precipitation regimes. Our ability to detect this and other patterns hinged on the compilation of multiple fine‐grained datasets, allowing us to contrast the effect of climate versus local conditions. We suggest that, in addition to sampling communities at local scales, we need to aggregate studies that span large ranges in climate variation in order to fully understand trait filtering at local, regional and global scales.

STRUCTURAL equation modeling ,SPECIES ,AQUATIC invertebrates ,SPATIAL variation - Abstract
Aim: Locally abundant species are usually widespread, and this pattern has been related to properties of the niches and traits of species. However, such explanations fail to account for the potential of traits to determine species niches and often overlook statistical artefacts. Here, we examine how trait distinctiveness determines the abilities of species to exploit either common habitats (niche position) or a range of habitats (niche breadth) and how niche position and breadth, in turn, affect abundance and occupancy. We also examine how statistical artefacts moderate these relationships. Location: Sixteen sites in the Neotropics. Time period: 1993–2014. Major taxa studied: Aquatic invertebrates from tank bromeliads. Methods: We measured the environmental niche position and breadth of each species and calculated its trait distinctiveness as the average trait difference from all other species at each site. Then, we used a combination of structural equation models and a meta‐analytical approach to test trait–niche relationships and a null model to control for statistical artefacts. Results: The trait distinctiveness of each species was unrelated to its niche properties, abundance and occupancy. In contrast, niche position was the main predictor of abundance and occupancy; species that used the most common environmental conditions found across bromeliads were locally abundant and widespread. Contributions of niche breadth to such patterns were attributable to statistical artefacts, indicating that effects of niche breadth might have been overestimated in previous studies. Main conclusions: Our study reveals the generality of niche position in explaining one of the most common ecological patterns. The robustness of this result is underscored by the geographical extent of our study and our control of statistical artefacts. We call for a similar examination across other systems, which is an essential task to understand the drivers of commonness across the tree of life. [ABSTRACT FROM AUTHOR]

For each zone, all the vascular epiphytes were counted and identified at species level. In Zone V, living and dead branches were differentiated. Data were analyzed with general linear mixed models and multivariate analysis. Fourteen species of vascular epiphytes were recorded (nine holoepiphytes, two facultative and three accidental epiphytic species) of four families (Bromeliaceae, Cactaceae, Polypodiaceae and Anacardiaceae). The richest family was Bromeliaceae, with seven species of the genus Tillandsia and Aechmea distichantha. The most abundant species was Tillandsia recurvata. Prosopis spp. had the highest abundance of epiphytes and S. obtusifolium the highest richness. Zone V had the highest average abundance and richness of vascular epiphytes. There were quantitative differences in species composition between phorophytes: A. distichantha and T. loliacea were positively associated with S. obtusifolium. Prosopis spp. had the highest abundance and richness in dead branches and the phorophytes of the upper stratum in the living ones. The differences in abundance, richness, specific composition and vertical distribution of vascular epiphytes between phorophytes could be attributed to their morphological characteristics and the microhabitats conditions in the trunk and branches.

Los bosques del este de la provincia de Formosa (Argentina), pertenecientes al Distrito del Chaco Húmedo, se distribuyen formando una coenoclina desde el borde del albardón del curso de agua, donde se encuentra el llamado ‘Bosque Ribereño’, desarrollándose en la zona intermedia un ‘Bosque Transicional’, hasta la parte topográficamente más baja con el ‘Quebrachal’ de Schinopsis balansae, denominado ‘Monte Fuerte’. La distribución de las especies en los tres tipos de bosques podría estar explicada por la capacidad de las plantas para sobrevivir a diferentes condiciones de disponibilidad hídrica. En la presente tesis se estudian la composición florística, abundancia, riqueza y diversidad del banco de renovales de las tres comunidades boscosas, así como ciertas condiciones ambientales del sotobosque (e.g. porcentaje de cobertura y altura del canopeo, cantidad de hojarasca, cobertura del sotobosque, presencia de especies Bromeliáceas, topografía local) y se evalúa experimentalmente la tolerancia de las plántulas de algunas especies leñosas (Peltophorum dubium, Enterolobium contortisiliquum, Gleditsia amorphoides, Microlobius foetidus, Diplokeleba floribunda, Caesalpinia paraguariensis, Prosopis nigra y Schinopsis balansae) a condiciones controladas de anoxia y de sequía. La mayoría de las variables evaluadas en el estudio florístico y ambiental del sotobosque permiten ordenar a los tres tipos de bosques en un gradiente que se corresponde con su ubicación en el área de estudio. El Bosque Ribereño es el bosque de mayor magnitud en cuanto a su cobertura y altura del canopeo, y producción de hojarasca, y ocurrió lo contrario con el Monte Fuerte. El Bosque Transicional presentó características ambientales intermedias, asemejándose en algunas de ellas a uno u otro de los dos bosques restantes. A pesar de la proximidad de estos bosques, la diferencia fundamental en el banco de renovales entre los mismos radica en su composición florística. El Bosque Ribereño es el más rico en número de individuos totales, especies y familias. Le sigue el Bosque Transicional, y luego el Monte Fuerte. Asimismo, el Bosque Ribereño resultó superior al resto de los bosques en abundancia y riqueza promedios, mientras que no hubo diferencias en diversidad y equitatividad entre ellos. En condiciones controladas, las plántulas de todas las especies resultan menos tolerantes a las condiciones de anoxia permanente, que al nivel de ‘sequía’ implementado. Ninguna de las especies vio afectado su crecimiento en el tratamiento ‘sequía’. Los resultados obtenidos en este trabajo permitieron confirmar que el banco de renovales de los bosques presentes en el área de estudio se diferencia principalmente por su composición florística, lo que determinaría, a la madurez, una estructura fisonómica diferenciada. La tolerancia de las plántulas de las especies estudiadas a la condición de sequía implementada, puede estar relacionada con la pertenencia de varias de dichas especies a bosques que, por su composición florística y distribución geográfica, corresponden al dominio de los Bosques Tropicales Estacionalmente Secos. The forests of eastern Formosa province (Argentina), belonging to the Humid Chaco District, are distributed forming a coenoclina from the edge of watercourses, where the so-called ‘Riparian Forest’ is located, the 'Transitional Forest' developing in intermediate zones, to lower places with a Schinopsis balansae dominated forest, called ‘Hardwood Forest’. The species distribution in the three forest types could be explained by the ability of plants to survive in different conditions of water availability. In this thesis, species composition, abundance, richness and diversity of sapling bank of the three forest communities are studied, as well as understory environmental conditions (e.g. percentage of canopy cover and height, leaf litter amount, understory coverage, Bromeliad species presence, local topography). Tolerance to flooding and drought conditions of some woody species seedlings (Peltophorum dubium, Enterolobium contortisiliquum, Gleditsia amorphoides, Microlobius foetidus, Diplokeleba floribunda, Caesalpinia paraguariensis, Prosopis nigra and Schinopsis balansae) is experimentally evaluated. Most of the variables evaluated in the understory environmental and floristic study sort the three forest types along a gradient matching their location in the field. The Riparian Forest is the forest of greater magnitude in terms of coverage, canopy height and litter production, and the opposite occurred with the Harwood Forest. The Transitional Forest presented intermediate environmental characteristics, resembling one or another of the two remaining forests. Despite the proximity of these forests, the main difference in the sapling bank consists of their floristic composition. The Riparian Forest is the richest in number of total individuals, species and families. The Transitional Forest follows it, and then the Hardwood Forest. Additionally, the Riparian Forest was superior to other forests in average abundance and richness, whereas no significative differences in diversity and evenness were found. Under controlled conditions, seedlings of all species were less tolerant to permanent anoxic conditions than to the 'drought' level implemented. The growth of no species was affected in the 'drought' treatment. The results obtained in this work allow to confirm that the seedling bank of forests in the study area differ mainly by their floristic composition, which would determine, at maturity, a distinct physiognomic structure. The tolerance of seedlings of the species studied under implemented drought condition may be related to the membership of several of these species to forests which, by their floristic composition and geographical distribution, belong to the Seasonally Dry Tropical Forests Dominium.
