Reducing bias in density estimates for unmarked populations that exhibit reactive behaviour towards camera traps

open access: yesMethods in Ecology and Evolution, Volume 14, Issue 12, Page 3100-3111, December 2023., 2023
Abstract Density estimates guide wildlife management, and camera traps are commonly used to estimate sizes of unmarked populations. Unfortunately, animals often alter their natural behaviour in the presence of camera traps, which may bias subsequent density estimates.

Outdoor recreation alters terrestrial vertebrate scavenger assemblage and carrion removal in a protected Mediterranean wetland

open access: yesAnimal Conservation, Volume 26, Issue 5, Page 633-641, October 2023., 2023
We found that outdoor recreation alters the vertebrate scavenger assemblage and carrion removal. Larger scavenger species are most affected, especially raptors. Furthermore, human activities promote the presence of non‐native species in the ecosystem. Therefore, areas of restricted access are essential to preserve biodiversity and ecological processes ...

Evaluating the impact of caribou habitat restoration on predator and prey movement

open access: yesConservation Biology, Volume 37, Issue 2, April 2023., 2023
Abstract Fragmentation of the boreal forest by linear features, including seismic lines, has destabilized predator–prey dynamics, resulting in the decline of woodland caribou (Rangifer tarandus caribou) populations. Restoration of human‐altered habitat has therefore been identified as a critical management tool for achieving self‐sustaining woodland ...

Remarkable altitudinal range extension of Eira barbara Tayra (Mammalia: Mustelidae)

open access: yesACI Avances en Ciencias e Ingenierías, 2015
Eira barbara Tayra has been reported across its geographic range from elevations between 0-2400 m, being rare above 1200 m. We report four records of E. barbara above 2600 m, obtained by using camera trapping.

Effects of deforestation and fragmentation on the fauna of land mammals and varzea forests of the northern Ecuadorian Amazon

open access: yesACI Avances en Ciencias e Ingenierías, 2012
From April 2008 through May 2009, we carried out two complementary studies to evaluate the effects of deforestation and fragmentation on the diversity of terrestrial mammals and on the behavior of the primate Callithrix pygmaea (pygmy marmoset) in varzea
