Context Habitat loss is a major factor influencing declines in landscape connectivity for many species, but forest patch configuration and changes in matrix permeability can also represent important drivers. An evaluation of which of these factors are predominant is key to guiding landscape planning at a regional scale. Objectives We aimed to qua...

Poaching can have major impacts on wild animal populations and is pervasive in tropical regions. The spatial distribution of this furtive activity is particularly difficult to estimate in large natural areas, and this hinders the development of effective anti-poaching strategies. We used passive acoustic recorders in combination with occupancy mode...

Canopy camera trapping is being increasingly used to characterize assemblages of arboreal mammals. In this study we compared, for the first time, the assemblage of arboreal mammals of the Atlantic Forest, surveyed using canopy camera trapping at two protected areas of Mis-iones, Argentina: Piñalito (11 camera-trap stations) and Cruce Caballero (9 s...

RED LIST ASSESSMENT OF THE MAMMALS OF ARGENTINA 2019: SUMMARY AND ANALYSIS OF THREATS. Assessing the extinction risk of species has become an important decision tool for the implementation of species conservation policies. In this work we summarize the result of the latest oficial categorization of the mammals of Argentina with emphasis on the thre...

Context. Habitat loss is a major factor influencing declines in landscape connectivity for many species, but forest patch configuration and changes in matrix permeability can also represent important drivers. To evaluate which of these factors are predominant is key to guiding landscape planning at a regional scale. Objectives. We aimed to quantify...

Natural environments worldwide are increasingly restricted to smaller and isolated patches, resulting in major threats to biodiversity. To prioritize conservation efforts, it is important to assess the relative contribution of the habitat remnants to landscape connectivity. We prioritized remnants of Atlantic Forest in Argentina based on their cont...

Motivation Population trend information is an ‘Essential Biodiversity Variable’ for monitoring change in biodiversity over time. Here, we present a global dataset of 1122 population trends describing changes in abundance over time in large mammals from the Order Carnivora – some of the world’s most charismatic and functionally important fauna. Mai...

The jaguar, an important symbol across the Americas, is one of the three largest cats in the world. Despite the ecological and cultural importance of this species, its populations are decreasing due to numerous threats such as habitat loss and degradation, poaching, prey depletion, among others. Prior to 1900s, the jaguar lived from southern United...

Land-use and climate change have been linked to wildlife population declines, but the role of socioeconomic factors in driving declines, and promoting population recoveries, remains relatively unexplored despite its likely importance. Here, we evaluate a comprehensive array of potential drivers of population changes observed in some of the world's...

Large terrestrial carnivores have undergone some of the largest population declines and range reductions of any species, which is of concern as they can have large effects on ecosystem dynamics and function.1 , 2 , 3 , 4 The jaguar (Panthera onca) is the apex predator throughout the majority of the Neotropics; however, its distribution has been red...

Species’ activity patterns are driven by the need to meet basic requirements of food, social interactions, movement, and rest, but often are influenced by a variety of biotic and abiotic factors. We used camera-trap data to describe and compare the activity patterns of the relatively poorly studied tayra (Eira barbara) across 10 populations distrib...

Aim Trait data are widely used in ecological and evolutionary phylogenetic comparative studies, but often values are not available for all species of interest. Traditionally, researchers have excluded species without data from analyses, but estimation of missing values using imputation has been proposed as a better approach. However, imputation met...

The range-wide management of the jaguar (Panthera onca) depends upon maintaining core populations connected through multi-national, transboundary cooperation, which is dependent upon understanding the movement ecology and space use of jaguars throughout their range. Using 117 telemetry trajectories from 12 ecoregions, we examined the landscape-leve...

Por su continuidad espacial y su relativa homogeneidad ecológica y biofísica, las ecorregiones son un nivel de organización apropiado para discutir y planificar iniciativas de conservación del ambiente a escala regional y nacional. Las interacciones complejas entre las características ecológicas de las ecorregiones, los cambios socioeconómicos loca...

Tabla A2. Puntaje de cada presión (de 0 a 100, con valores más altos reflejando una mayor incidencia de la misma) en las ecorregiones terrestres de Argentina en base a su jerarquización sobre cuatro dimensiones.

Assessments of the role that small (<500 km²) protected areas play in conservation of large carnivores in landscapes where the species are persecuted are scarce. Using camera-trap sampling we estimated puma (Puma concolor) population abundance, site use intensity, and relative abundance of prey in Lihué Calel National Park (320 km²) and two neighbo...

Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across...

Four Neotropical small and medium felids—the ocelot, jaguarundi, margay, and southern tiger cat—have overlapping geographic distributions in the endangered Atlantic Forest. Local studies show that these felids avoid areas with high human impact, but the three smaller ones use human-modified areas more frequently than do ocelots. To understand how l...

Home range estimation is routine practice in ecological research. While advances in animal tracking technology have increased our capacity to collect data to support home range analysis, these same advances have also resulted in increasingly autocorrelated data. Consequently the question of which home range estimator to use on modern, highly autoco...

Habitat loss and fragmentation represent major threats for the conservation of apex predators, such as the jaguar (Panthera onca). Investigating species' resource selection behavior in response to landscape alteration is critical for developing relevant conservation management plans. The jaguar is found across a variety of habitats with different g...

Large carnivores are key elements of natural ecosystems and most of them are declining due to the impacts of human activities. Jaguars and pumas are the largest felids of the American continent, and particularly jaguars are critically endangered in the Atlantic Forest of South America. As with other tropical forests, the Atlantic Forest has been co...

Competition theory and niche theory suggest that two morphologically similar species may coexist by reducing the overlap of at least one dimension of their ecological niche. The medium and small Neotropical felids are an interesting group of carnivore species for studying intraguild competition. Due to differences in size it is expected that the la...

Here we compile a data set comprising morphological and life history information of 279 mammal species from 39,850 individuals of 388 populations ranging from 5.83 to 29.75 decimal degrees of latitude and 34.82 to 56.73 decimal degrees of lon- gitude in the Atlantic forest of South America. We present trait information from 16,840 individ- uals of...

Measures of traits are the basis of functional biological diversity. Numerous works consider mean species-level measures of traits while ignoring individual variance within species. However, there is a large amount of variation within species and it is increasingly apparent that it is important to consider trait variation not only between species,...

Protected areas – widely recognized as the main strategy for biodiversity conservation – have greatly expanded, covering ∼15% of the Earth; however, we still lack detailed information on biodiversity to evaluate their effectiveness. This is particularly urgent for biodiversity hotspots where protected areas are islands within human modified landsca...

Our understanding of mammal ecology has always been hindered by the difficulties of observing species in closed tropical forests. Camera trapping has become a major advance for monitoring terrestrial mammals in biodiversity rich ecosystems. Here we compiled one of the largest datasets of inventories of terrestrial mammal communities for the Neotrop...

Biodiversity loss is a major driver of ecosystem change, yet the ecological data required to detect and mitigate losses are often lacking. Recently, camera trap surveys have been suggested as a method for sampling local wildlife communities, because these observations can be collated into a global monitoring network. To demonstrate the potential of...

The giant armadillo (Priodontes maximus) is a difficult species to study because of low population densities, combined with nocturnal and fossorial habits. No systematic population studies have been undertaken to date in Argentina. Our objectives were to evaluate the species’ presence, relative abundance, and temporal activity patterns across five...

Habitat loss and fragmentation are among the major threats to the conservation of biodiversity. Improvement of landscape connectivity becomes one of the main strategies for alleviating these threats and is an increasingly used target in management policies worldwide. However, implementation of connectivity principles in local management actions oft...

Jaguar populations have been declining in Brazil mostly due to habitat loss and fragmentation, conflict with humans, poaching and reduction of prey. This is dramatically true in the Atlantic Forest, where occurrence of this large felid is now restricted to very few remaining areas. We used a non-invasive DNA analysis to search through felid scats c...

Accurately estimating home range and understanding movement behavior can provide important information on ecological processes. Advances in data collection and analysis have improved our ability to estimate home range and movement parameters, both of which have the potential to impact species conservation. Fitting continuous-time movement model to...
