Stereotypic route tracing in captive Carnivora is predicted by species-typical home range sizes and hunting styles [PDF]

, 2016
In captive conditions (e.g. zoos), some Carnivora species typically show negligible stereotypic behaviour (SB) and reproduce successfully, while others tend to reproduce poorly and be very stereotypic.

Demographic buffering in natural populations: A multi‐level perspective

Journal of Animal Ecology, EarlyView.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Respect for Grizzly Bears: An Aboriginal Approach for Co-existence and Resilience [PDF]

, 2009
Aboriginal peoples’ respect for grizzly bear (Ursus arctos) is widely acknowledged, but rarely explored, in wildlife management discourse in northern Canada.

Updating the forelimb anatomy of the domestic cat (Felis catus, Felidae) based on evolutionary inferences of its muscles and nerves I: Shoulder and brachium

Journal of Anatomy, EarlyView.
In this study, we provide a detailed description of the shoulder and brachium muscles and the brachial plexus of the domestic cat (Felis catus). We identified muscular variants (articularis humeri, coracobrachialis longus, biceps brachii caput breve), clarified the independence of the anconeus medialis muscle from the triceps brachii muscle, and ...

Osos y hombres: historia de un desencuentro. [PDF]

, 1996
La redacción de este texto ha constituido una de las experiencias personales más satisfactorias que podrían caberle al autor: de una parte, cuando aparezca impreso, habrá transcurrido un cuarto de siglo desde que se topó, por primera vez, con un hueso ...

State-space models' dirty little secrets: even simple linear Gaussian models can have estimation problems [PDF]

, 2016
State-space models (SSMs) are increasingly used in ecology to model time-series such as animal movement paths and population dynamics. This type of hierarchical model is often structured to account for two levels of variability: biological stochasticity ...

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

Biological Reviews, Volume 101, Issue 3, Page 1463-1478, June 2026.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Testosterone concentrations in juvenile male polar bears (Ursus maritimus)

Theriogenology Wild
The ex situ polar bear population in the United States is not sustainable. Current management practices include pairing mates at five to six years of age, but there is evidence that wild bears have sired cubs as early as two years old. Timing acquisition

Was the giant short-faced bear a hyper-scavenger? A new approach to the dietary study of ursids using dental microwear textures.

PLoS ONE, 2013
Dramatic environmental changes associated with global cooling since the late Miocene, and the onset of glacial-interglacial cycles in the Pleistocene served as a backdrop to the evolutionary radiation of modern bears (family Ursidae). These environmental

Project MOSI: rationale and pilot-study results of an initiative to help protect zoo animals from mosquito-transmitted pathogens and contribute data on mosquito spatio–temporal distribution change [PDF]

, 2015
Mosquito-borne pathogens pose major threats to both wildlife and human health and, largely as a result of unintentional human-aided dispersal of their vector species, their cumulative threat is on the rise.
