Abstract The Amazon forest has the highest biodiversity on Earth. However, information Amazonian vertebrate diversity is still deficient and scattered across published, peer‐reviewed, gray literature in unpublished raw data. Camera traps are an effective non‐invasive method of surveying vertebrates, applicable to different scales time space. In this study, we organized standardized camera trap records from regions compile most extensive data set inventories mammal, bird, reptile species ever...
Agricultural development was the major contributor to South America's designation as continent with highest rates of forest loss from 2000-2012. As apex predator in Neotropics, jaguars (Panthera onca) are dependent on cover but species' response habitat fragmentation heterogeneous agricultural landscapes has not been a subject extensive research. We used occupancy measure jaguar use Colombia's middle Magdalena River valley which, part intercontinental Tumbes-Chocó-Magdalena biodiversity...
Abstract: Fig trees ( Ficus spp) produce fruit year-round and figs are consumed by a large proportion of frugivores throughout the tropics. Figs potential keystone resources that sustain frugivore communities during periods scarcity, but studies have produced contradictory results. Over 1 y we monitored phenology 206 five species in Colombian cloud forest, to test whether low overall availability. We also measured fig tree densities 18 0.5-ha plots made 190 h observations at 24 three...
In tropical ecosystems, habitat degradation and fragmentation are some of the most important drivers biodiversity loss. Colombia, Magdalena River basin is home to a megadiverse wildlife community, which has been historically exposed pervasive loss fragmentation. Within long‐term project on conservation critically endangered brown spider monkeys ( Ateles hybridus ), we signed agreements with local landowners protect remaining forests reconnect them through restoration corridors. We...
Nocturnal curassows (Nothocrax urumutum) are one of the most enigmatic birds from South American rainforests. Their elusive habits and their nocturnal vocal behavior have led to generalized assumption that they differ other in presumable habits. Here, we compiled camera trap data long term projects Amazon rainforest Andes Cordillera piedmont describe temporal activity Curassows. Based on an overall sampling effort 68838 nights obtained 274 independent records activity. The results this study...
Abstract The blue-billed curassow Crax alberti is an endemic Colombian species categorized as Critically Endangered on the IUCN Red List because of effects hunting and habitat loss. Conservation management actions are required to ensure its persistence in forest remnants across range. We conducted a population viability analysis for municipality Yondó, Antioquia, based data collected field available information reproductive ecology species. evaluate seven realistic conservation scenarios by...
A species presence within its geographic range can be influenced by environmental variables and disturbance history, resulting in particular occupancy patterns. Understanding the factors affecting is essential to evaluate impact of human activities on design conservation or restoration measures. For tropical vertebrates, there little understanding how multiple influence interactions with other under different conditions levels. In this study, we evaluated natural human-mediated determine...
Los programas de conservación especies son una estrategia común para enfrentar la pérdida biodiversidad. El concepto paisaje se basa en selección un conjunto cuyas características permiten determinar y abordar presiones que afectan biodiversidad territorio. Esta aproximación tiene dos supuestos principales: las deriva 1) otras del sistema 2) protección estructura ecosistema. Para evaluar estas hipótesis usamos el ejemplo “Proyecto Vida Silvestre”, iniciativa desarrollada bajo esta áreas...
Fragmentation and habitat loss are some of the major threats to biodiversity, altered ecological processes important for regulation ecosystems that may eventually be associated species extinction. The response these phenomena occurs at different scales space-time, making study fragmentation its effect on in a challenge an urgent need conservation. In this sense article examines impacts interactions, organizational levels same time, we evaluate general way state research topic Latin America.
Abstract Tent‐making bats modify leaves to build refuges. Leaf modification involves energetic and defense costs that should be balanced by the benefits of tent‐roosting. The alteration leaf's vascular system reduces tent's life expectancy, so obtain a benefit, are expected use tents regularly as long they remain functional not more than necessary. Over 2 yr, we documented dynamics tent construction Uroderma convexum other bat species in palm Sabal mauritiiformis Colombian transitional dry...
Medir la fuerza de interacción es clave para comprender dinámica las redes mutualistas. Sin embargo, variación intraespecífica en los rasgos especies puede afectar patrones y resultados interacciones a una escala aún no medida. En este estudio, exploramos cómo individual producción frutos especie Ficus modula el consumo por aves. El grado, expresado como número especies, tasas visitas, expresadas individuos su equivalente biomasa, fueron independientes del tamaño cosecha. acumulado tres...
La pava caucana (Penelope perspicax) es un ave endémica de las laderas del valle geográfico río Cauca en Colombia, considerada peligro extinción. pérdida hábitat y la cacería han sido sus principales amenazas, lo que ha generado reducción aislamiento poblaciones. El objetivo este estudio fue determinar densidad poblacional una localidad los Farallones Cali desarrollar modelos ocupación, para evaluar factores expliquen el uso especie. Obtuvimos 9 ind.km-2, valor más bajo estimados disponibles...
