Liver X Receptor α (LXRα) Regulates 5β‐Reductase (AKR1D1) Expression in Avian Embryos: Implications for Yolk Steroid Metabolism

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Steroid‐mediated maternal effects are well‐studied as a source of phenotypic variation. In bird eggs, the yolk contains various steroids that can influence embryonic development. However, one complicating factor in understanding how yolk steroids affect development is that the embryo metabolizes yolk steroids to regulate exposure.

Monitoring mercury across the National Wildlife Refuge System using a biosentinel approach

open access: yesThe Journal of Wildlife Management, EarlyView.
We measured mercury concentrations in 1,356 dragonfly larvae collected from 30 National Wildlife Refuges across the United States and found wide variability among refuges, spanning the full range reported for other protected lands. Using a management‐focused mercury impairment index, 80% of refuges contained sites classified as moderate or higher risk.

Population dynamics of Townsend's big‐eared bats: effect of age and drought on survival

open access: yesThe Journal of Wildlife Management, EarlyView.
We estimated age‐specific yearly survival of female Townsend's big‐eared bats in Inyo and Mono Counties, California. We found that both juvenile and adult survival were negatively impacted by drought, and that detection probability was lower for hand‐recapture than for bats detected via pass‐through antenna arrays.

Environmental and temporal factors affecting record white‐tailed deer antler characteristics in Ontario, Canada

open access: yesThe Journal of Wildlife Management, EarlyView.
Antler characteristics are influenced by a combination of genetics, age, and environmental factors, notably habitat quality and resource availability. In this study, we explored how diverse environmental factors, including climate and land cover composition, affect antler size, tine configuration, and the distribution of record‐scoring white‐tailed ...
