![]() Based on this density and the buffer area of the sampling grids, we estimated an overall. Bears population density was 2.9 bears per 100 km². ![]() Sixteen (16) adults were recaptured (12 males and 4 females), with a maximum mean distance of 27.22 km. Fifty-seven (57) Andean bear individuals were identified according to key external morphological features. Two thousand seven hundred eighty-four (2,784) native fauna records were obtained, 1,456 corresponding to mammals, 183 records for Andean bear specimens, 158 of them independent bear records (at least one hour between records), and 106 effective-independent bear records (also permitting individual recognition). One hundred seventeen (117) camera traps were installed at 9 grids: 13 cameras per grid, each camera separated 750 m from the other the sampling effort was 17,057 days-trap. ![]() more The Andean bear (Tremarctos ornatus) population density and relative abundance within the Chingaza Massif were assessed between September 2015 and May 2016. The Andean bear (Tremarctos ornatus) population density and relative abundance within the Chingaz. The forest-páramo ecotone, full of dry-season-fruiting Ericaceae shrubs, was the main habitat used. Total daily traveled routes oscillated between 0.51-12.07 km. K-NNCH and KDE were the most accurate methods, as they excluded degraded terrain not used by the tracked bear. This finding supports the hypothesis that more fragmented landscapes demand greater movements to obtain sufficient resources. Our dry-season male home range estimates with nearest-neighbor convex-hull (K-NNCH, 24.62 km2) and kernel density estimate (KDE, 42.15 km2) slightly exceed those reported for the species in Ecuador, and our minimum convex polygon (MCP, 238.86 km2) quintupled estimates from Ecuador. Bear locations (n= 348) were obtained between October and December 2013, during the dry season. The use of space for this species was measured for the first time in Colombia with a male specimen tracked with GPS telemetry. more For decades, telemetry has provided large amounts of ecological information for several bear species however, for the Andean bear (Tremarctos ornatus), only three studies have available information. Todos los datos recibidos fueron organizados en los.įor decades, telemetry has provided large amounts of ecological information for several bear spec. Esto registros provienen de 56 organizaciones y 121 autores que compartieron sus datos para la publicación. Los órdenes con mayor representatividad fueron Carnívora (35.97%), Rodentia (28.56%) y Artiodactyla (16.55%). Con base a ello, se obtuvieron un total de 19.999 registros, que permitieron obtener información para 10 órdenes, 26 familias, 50 géneros y 66 especies. ![]() more Con de propósito de aunar esfuerzos técnicos, administrativos y financieros entre el Instituto Alexander von Humboldt y la Asociación Colombiana de Zoología (ACZ), para identificar, gestionar y consolidar los registros biológicos e información sobre ecología, uso y amenazas de un grupo determinado de especies de mamíferos de Colombia, de acuerdo con las necesidades de información del sistema de categorización y criterios de la UICN, se generó una base de datos de registros a partir de información de fototrampeo de diferentes investigadores y instituciones interesadas.
