Detecting changes in distribution and abundance using harvest data in two sympatric bear species in Southeast Alaska

open access: yesWildlife Biology, EarlyView.
Monitoring wildlife populations in remote landscapes is challenging due to the difficulties of conducting field surveys. However, harvest data, which are routinely collected by management agencies, offer valuable insights into population trends. Brown bear Ursus arctosand American black bear U.

Life‐history stages and behavior influence demographic classification of moose captured on remote cameras

open access: yesWildlife Biology, EarlyView.
Obtaining accurate information on demographic states, such as the age and sex classes of animals, is an important step for monitoring wildlife populations. Traditionally, demographic data are collected from harvest, aerial surveys and telemetry studies.

The status quo is imperiled: Acknowledging the issue of range‐shifting wildlife species

open access: yesWildlife Society Bulletin, EarlyView.
Rapid climate and land‐use change are reshaping wildlife distributions, forcing managers to confront difficult decisions that challenge the traditional “status quo” approach. Range contractions of snow‐dependent species such as the snowshoe hare (Lepus americanus; left photo) may increasingly require practitioners to recognize and plan for unavoidable ...

Localized resources enable noninvasive genetic monitoring of small populations of mountain ungulates

open access: yesWildlife Society Bulletin, EarlyView.
Using microsatellite analysis of fecal samples collected at mineral licks from 2019–2022, we assessed abundance, apparent survival and genetics of bighorn sheep in the Teton Range, Wyoming, USA. Annual abundance estimates ranged from 118−132 individuals split into 2 similar‐sized demes and apparent survival estimates ranged from 0.72–0.92.

Nutrimental Determinants of Chronological Aging and Competitiveness in the snf1Δ Warburg Model

open access: yesYeast, EarlyView.
Deletion of SNF1 in Saccharomyces cerevisiae alters chronological aging in a nutrient‐dependent manner, shortening lifespan under low‐nutrient conditions and extending it under high‐glucose and high‐amino‐acid conditions. Under nutrient‐rich conditions, the snf1∆ strain also showed an approximately 2‐log increase in competitiveness relative to the wild

Adjusting Our Thinking About Feeding Animals: Fiber as the Metric for Mimicking Natural Diets

open access: yesZoo Biology, EarlyView.
A typical effect of the change of an animal group to a diet higher in fiber: juveniles keep growing, animals of ideal body weight maintain their weight, and obese individuals lose weight. ABSTRACT Free‐ranging animals often ingest markedly different diets than their counterparts under human care, whether companion animals, production animals, or zoo ...
