Evaluation of black bear (Ursus americanus) diet and consequences in its conservation in Sierra de Picachos, Nuevo León, Mexico

Revista Mexicana de Biodiversidad, 2013
Black bears (Ursus americanus) are considered endangered in Mexico. In northern Mexico, bears are considered responsible for preying on livestock, damaging private property, and crops; therefore they are killed to protect locals’ livelihoods. There is a

YIPFα1A expression is regulated by multilayered molecular mechanisms

FEBS Open Bio, EarlyView.
YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.

Status and Food Preferences of Bears in Sub Alpine Scrub Forests, AJK

Journal of Bioresource Management, 2018
Bears belong to the family Ursidae, under the order Carnivora with eight extant species (Grzimek, 2003). Roberts (1997) cite the presence of Himalayan brown bear, Himalayan black bear and Balochistan black bear in Pakistan.

The potential of electrified barriers to keep black bears out of fenced road corridors at low volume access roads [PDF]

Nature Conservation
Fences can reduce wildlife-vehicle collisions, but it is not always possible to fence over long distances, especially not in multi-functional landscapes.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

FEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Epigenetic Clock in Bears: A Simple Cost‐Effective Blood DNA Methylation‐Based Age Estimation Method Applicable to Multiple Bear Species

Ecology and Evolution
Age is an essential factor to understand the life history and demographic parameters of wildlife. Previously, we established an age estimation method for brown bears based on blood DNA methylation level.

Determining causes of genetic isolation in a large carnivore (Ursus americanus) population to direct contemporary conservation measures. [PDF]

PLoS ONE, 2017
The processes leading to genetic isolation influence a population's local extinction risk, and should thus be identified before conservation actions are implemented. Natural or human-induced circumstances can result in historical or contemporary barriers

The C‐terminal region of KIF26B is indispensable for nephron progenitor condensation and kidney formation in mice

FEBS Open Bio, EarlyView.
KIF26B plays an important role in kidney development. We engineered mice lacking the C‐terminal region of KIF26B and found severe kidney defects, including bilateral renal agenesis, similar to full Kif26b knockout mice. The mutation disrupted nephron progenitor condensation and reduced Gdnf‐Wnt11 signaling, showing that the KIF26B C‐terminal region is ...

BEARS IN PAKISTAN: DISTRIBUTION, POPULATION BIOLOGY AND HUMAN CONFLICTS

Journal of Bioresource Management, 2015
We conducted questionnaire based interviews (n = 1873) of respondents coming from 258 localities about bear tracts in northern parts of Pakistan in 2012-2014 to study Himalyan brown (U. arctos isalbellinus) and Himalayan black (U. t.

Intrapopulation diversity in isotopic niche over landscapes: Spatial patterns inform conservation of bear–salmon systems

Ecosphere, 2017
Intrapopulation variability in resource acquisition (i.e., niche variation) influences population dynamics, with important implications for conservation planning.
