Assessing physiological, behavioral and movement responses to Suprelorin implant delivery methods in free‐ranging eastern grey kangaroos Macropus giganteus

Wildlife Biology, EarlyView.
Overabundant populations of eastern grey kangaroos Macropus giganteus in peri‐urban areas pose ecological and social challenges. Current management strategies are often hindered by animal welfare and logistical concerns. This study aimed to assess stress responses of kangaroos to two contraceptive delivery methods.

ŠTETE OD MRKOG MEDVJEDA (URSUS ARCTOS L.) NA ŠUMSKIM SASTOJINAMA U SREDNJOBOSANSKOM KANTONU

Radovi Šumarskog fakulteta Univerziteta u Sarajevu, 2008
UDK 639.111.7:630*45(497.6) Medvjed mrki (Ursus arctos L.) je najkrupnija vrsta karnivora u Bosni i Hercegovini. Usljed kompeticije za resurse sa ljudima, ova vrsta je nestala iz najvećeg broja evropskih zemalja prije više stotina godina. U Bosni i Hercegovini, intenzivno gazdovanje medvjdom provodi se od 1955. godine.

Development of optimized methods for unbiased dusky grouse population monitoring using real and simulated data

Wildlife Biology, EarlyView.
Rigorous state‐wide monitoring programs are lacking for dusky grouse Dendragapus obscurus, a North American species of forest grouse with relatively low detectability that is found in coniferous and mountainous areas in the western United States and Canada.

Minimal impact of spotted hyenas on livestock and endangered species in a prey‐rich ecosystem

Wildlife Biology, EarlyView.
The diet of large carnivores is of great interest to conservation managers, as it can reveal the extent of human–carnivore conflict and the impact of carnivores on species of high conservation priority. Metabarcoding of environmental DNA can identify species and is often more reliable than observational or morphological methods, particularly when it ...

Cranial Morphological Distinctiveness Between Ursus arctos and U. americanus

, 2017
Despite being separated by millions of years of evolution, black bears (Ursus americanus) and brown bears (Ursus arctos) can be difficult to distinguish based on skeletal and dental material alone.

A complete mitochondrial genome sequence of Asian black bear Sichuan subspecies (Ursus thibetanus mupinensis)

International Journal of Biological Sciences, 2007
We obtained the complete mitochondrial genome of U.thibetanus mupinensis by DNA sequencing based on the PCR fragments of 18 primers we designed. The results indicate that the mtDNA is 16 868 bp in size, encodes 13 protein genes, 22 tRNA genes, and 2 rRNA

Consumption of anthropogenic foods influences the nutritional and reproductive condition of hunter‐harvested black bears

Wildlife Biology, EarlyView.
The consumption of human food subsidies influences ecological processes, and can affect individual behavior and fitness with population level changes in abundance and distribution. American black bears Ursus americanus often consume human food subsidies, which have been correlated with increased bear body size, age‐specific fertility and mortality ...

Delisting the Northern Rocky Mountain gray wolf from the US Endangered Species Act: an assessment of political discourse over 20 years

Wildlife Biology, EarlyView.
Feared, revered, and politicized, wolves have long captured human imagination, and ignited fierce conservation conflicts. In the United States, the Endangered Species Act protects species at risk of extinction from human impacts. This far‐reaching legislation, which impacts development and state‐level wildlife management, has been fraught with legal ...

Le gisement pléistocène supérieur de la grotte de Jaurens à Nespouls, Corrèze, France : Les carnivores (Mammalia, Carnivora). III. Ursidae, Ursus arctos Linnaeus

, 1983
The Jaurens site has yielded remains of a large ursid. Not less than six individuals are present. In consequence of a traumatism, the muzzle and forehead of a male are strongly put out of shape. A comparative study is made with Ursus arctos, U. deningeri
