We present this collection her...

Domestic dogs (Canis lupus familiaris) are recognised worldwide not only as man’s best friend, but also as a form of anthropogenic edge effect impacting wildlife through predation, competition and disease infection. In the Northern Andes, there is growing evidence of dogs inducing activity shifts or alterations in the habitat use of native mammalia...

Agricultural simplification continues to expand at the expense of more diverse forms of agriculture. This simplification, for example, in the form of intensively managed monocultures, poses a risk to keeping the world within safe and just Earth system boundaries. Here, we estimated how agricultural diversification simultaneously affects social and...

Mesocarnivores play a key role in ecosystem dynamics through the regulation of prey populations and are sensitive to environmental changes; thus, they are often considered good model organisms for conservation planning. However, data regarding the factors that influence the habitat use of threatened small wild felids such as the Andean tiger cat (L...

Los refugios imponen presiones selectivas a los murciélagos. Los refugios proporcionan sitios de apareamiento, hibernación y crianza; promueven interacciones sociales, digestión de alimentos; y ofrecen protección contra el clima adverso y los depredadores. Por ende, tienen un papel importante en la ecología y evolución de estos mamíferos. En este t...

La evaluación de riesgo de extinción de los mamíferos de Colombia se ha realizado heterogéneamente en los últimos 16 años. Sin embargo, las evaluaciones de los mamíferos de Colombia están desactualizadas. Por esta razón, se hace necesario renovar la evaluación del riesgo de extinción de los de mamíferos de Colombia. Este proceso se realiza de maner...

Sexual selection is an evolutionary mechanism, physiological and morphological where the differential behavior between the sexes has a large variation in reproductive success. In frogs, the male strategy is to use their calls to attract females. In this study, we have performed call selection experiments by the females, using recordings of male cal...

A partir del Índice de Huella Espacial Humana se evidenció una reducción del 15 % en las áreas idóneas para la presencia del oso andino en Colombia entre 1970 y el 2015. Esto podría llevar a que las poblaciones en el sur se aislaran respecto de las que se distribuyen en el norte de Colombia y en Venezuela.

Twelve species of ungulates are present in Colombia, represented by three species of tapirs, two of peccaries and seven species of deer. A synthesis about the evolutionary and recent history for each of the group is presented, highlighting recent paleontological information for northern South America. Genetic and molecular studies indicate that dee...

Cattle ranching is historically and geographically the most extended land use in Colombia with up to 35 million hectares dedicated to this activity. As such, it is considered one of the main drivers of biodiversity loss and the largest source of CO2 emissions in the country. Thus, how these areas are managed may have a large impact on avoiding biod...

In carrying out a rapid inventory of the Bajo Caguán-Caquetá region, the objective of this study was to record species, estimate their richness and abundance, and identify threats of mammal species. We found large predators with reduced populations, such as giant river otter (Pteronura brasiliensis), and large primates like white-bellied spider mon...

Species distribution models (SDMs) are statistical tools used to develop continuous predictions of species occurrence. ‘Integrated SDMs’ (ISDMs) are an elaboration of this approach with potential advantages that allow for the dual use of opportunistically collected presence-only data and site-occupancy data from planned surveys. These models also a...

Due to the fast deforestation rates in the tropics, multiple international efforts have been launched to reduce deforestation and develop consistent methodologies to assess forest extension and change. Since 2010 Colombia implemented the Mainstream Sustainable Cattle Ranching project with the participation of small farmers in a payment for environm...

Como muchos biólogos interesados en monitorear o estudiar mamíferos medianos y grandes, en estado silvestre, me he enfrentado a las clásicas preguntas como: ¿Cuántas cámaras necesito?, ¿Qué cámara compramos?, ¿Cómo las instalo? ¿Qué protocolos sigo? ¿Y qué más puedo hacer con esos datos? En esta corta revisión pretendo resumir las respuestas a esas...

Aim We test a new species distribution modelling ( SDM ) framework, while comparing results to more common distribution modelling techniques. This framework allows for the combination of presence‐only ( PO ) and presence‐absence ( PA ) data and accounts for imperfect detection and spatial bias in presence data. The new framework tested here is base...

Neotropical dry forests are among the most diverse and threatened ecosystems worldwide. The extent and knowledge of Neotropical dry forests are quite heterogeneous with forests located in the Ecuadorian province especially diverse, threatened and poorly studied. In this work, we review patterns and conservation status of biodiversity, ecosystem pro...

Conservation targets: Top predators such as giant river otter (Pteronura brasiliensis), listed as Endangered by the IUCN and the government of Peru, and jaguar (Panthera onca); healthy populations of species locally extinct in other areas of Loreto, like woolly monkey (Lagothrix lagotricha), tapir (Tapirus terrestris), and white-lipped peccary (Tay...

Biodiversity conservation requires maintaining an updated knowledge of the species. Therefore, we developed an updated check-list of woody plant species in Machalilla National Park, using three complementary data sources: i) publications and reports, ii) herbarium specimens, and iii) and botanical databases. A total of 579 morpho-species, belonging...

Understanding the abundance, geographicdistribution, and conservation status of terrestrial mam­mals is vital to promote effective wildlife management in protected areas. Located in the Tumbes-Chocó-Magdalena hotspot of western Ecuador, Machalilla National Park contains high levels of biodiversity and endemism but suffers from habitat loss and degr...

Ecuador is a megadiverse country with high endemism rates. However, very few studies describe the diversity and abundance of medium and large mammals in protected areas of the coast. In this work we carried out the first inventory of medium size and large mammals for the marine and coastal wildlife refuge of Pacoche (RVSMCP) in Ecuador.Methods: 60...

Accurate information on the distribution, demography, and conservation status of endangered populations in threatened habitats are essential to provide the basis for conservation actions and management plans. Neglect of western Ecuador by biologists has resulted in a paucity of information of primate populations in the region. Capuchins (Cebus spp....

eforestation is still a problem in the Amazon and its study has sometimes been merely descriptive, relating its increase or decrease to possible direct causes such as economic or demographic variables. However, deforestation is also indirectly influenced by other variables, better known as underlying causes, being one of them the institutional cont...

I dentifying species distributions is fundamental to understanding their ecology and guiding conservation and management strategies. We compiled 756 unique range-wide Baird's tapir (Tapirus bairdii) detections via camera trapping of track/sign surveys in eight countries. We then estimated the distribution of suitable tapir habitat within a Maxent-m...

A pesar de que su presencia ha sido confirmada en varias localidades de la Cordillera Central en los Andes, la distribución de la danta de montaña (Tapirus pinchaque; <200 kg; EN) ha sido poco estudiada en Colombia. Por ello, se han estimado las áreas potenciales de distribución actual y bajo escenarios de cambio climático futuros, considerando el...

In Ecuador, Tapirus pinchaque is considered to be critically endangered. Although the species has been registered in several localities, its geographic distribution remains unclear, and the effects of climate change and current land uses on this species are largely unknown. We modeled the ecological niche of T. pinchaque using MaxEnt, in order to a...
