Optimizing fecal DNA collection and storage techniques for noninvasive genetic sampling of river otters

open access: yesWildlife Society Bulletin, Volume 49, Issue 4, December 2025.
This study compared 2 non‐invasive DNA collection methods for river otters and found that fecal swabbing consistently outperformed DETs buffer storage across both temperate and tropical environments. Swabbing yielded higher PCR and genotyping success rates while reducing genotyping errors, particularly when sampling anal jelly in tropical conditions ...

Genética de poblaciones amazónicas: la historia evolutiva del jaguar, ocelote, delfín rosado, mono lanudo y piurí, reconstruida a partir de sus genes [PDF]

open access: yes, 2007
The Amazon has more than the half of the world's biodiversity. Nevertheless, the major fraction of the Amazon species has unknown evolutionary histories. This is also certain for mammals and birds.

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

Antipredatory behavior of giant anteaters (Myrmecophaga tridactyla) in captivity [PDF]

open access: yes, 2014
Muchos mamíferos son capaces de percibir y responder al riesgo de depredación a partir de señales emitidas por sus depredadores, aún en ausencia de una experiencia ecológica, evolutiva e incluso de ambas.

Comparative assessment of local ecological knowledge and line‐transect surveys for assessing species occupancy

open access: yesConservation Science and Practice, Volume 7, Issue 12, December 2025.
Comparing Local Ecological Knowledge(LEK) to Line‐Transect Surveys for Estimation of Species Occupancy in Central Amazon. We highlight the potential of complementing LEK‐based approaches with traditional surveys to attempt more comprehensive, rapid and cost‐effective monitoring of biodiversity.

Discrimination of Individual Tigers (\u3cem\u3ePanthera tigris\u3c/em\u3e) from Long Distance Roars [PDF]

open access: yes, 2013
This paper investigates the extent of tiger (Panthera tigris) vocal individuality through both qualitative and quantitative approaches using long distance roars from six individual tigers at Omaha\u27s Henry Doorly Zoo in Omaha, NE.

Growing sabers: Mandibular shape and biomechanical performance trajectories during the ontogeny of Smilodon fatalis

open access: yesThe Anatomical Record, Volume 308, Issue 11, Page 2976-2993, November 2025.
Abstract The evolution of organisms can be studied through the lens of developmental systems, as the timing of development of morphological features is an important aspect to consider when studying a phenotype. Such data can be challenging to obtain in fossil amniotes owing to the scarcity of their fossil record. However, the numerous remains of Rancho

Notas de ixodologia: VII - Otocentor nitens Neuman, 1897) versus Anocentor columbianus Schulze, 1937 e comentários sôbre a rápida disseminação desse ixodideo no Brasil (Acari: Ixodidae)

open access: yesMemorias do Instituto Oswaldo Cruz, 1953
Anocentor columbianus Schulze, 1937 is a synonym of Otocentor nitens (Neumann, 1897). Otocentor Cooley, 1938 becomes a synonym of Anocentor Schulze 1937. The correct name of the species is now Anocentor nitens (Neumann, 1897).
