Nutrition regulates reproductive senescence and terminal investment across the reproductive cycle of a long-lived mammal

Scientific Reports
Deterioration in nutritional condition with aging could reduce reproductive success but coincides with declines in residual reproductive potential, thus invoking opposing expectations for late-life reproduction.

Population genomics of free‐ranging Great Plains white‐tailed and mule deer reflects a long history of interspecific hybridization

Evolutionary Applications, 2022
Hybridization is a natural process at species‐range boundaries that may variably promote the speciation process or break down species barriers but minimally will influence management outcomes of distinct populations.

Tree Squirrels Selectively Disperse High‐Quality Acorns Away From Tree Trunks

Integrative Zoology, EarlyView.
Acorn quality and squirrel feeding behavior significantly structured spatial dispersal patterns of two Californian oak species. Non‐infested acorns were preferentially selected for embryo excision and dispersed farther than infested ones. Acorns were fully consumed near tree trunks, signaling rapid feeding in safe refuges, whereas non‐eaten, partially ...

Coursing the mottled mosaic: Generalist predators track pulses in availability of neonatal ungulates

Ecology and Evolution, 2023
The density and distribution of resources shape animal movement and behavior and have direct implications for population dynamics. Resource availability often is “pulsed” in space and time, and individuals should cue in on resource pulses when the ...

Smoke signals: Measuring wildlife smoke exposure with animal‐borne and stationary sensors

Methods in Ecology and Evolution, EarlyView.
Abstract Wildfires are becoming larger, more frequent and more severe, producing smoke plumes that degrade air quality hundreds of kilometres away and for days to weeks after an active fire. Despite public health and safety concerns regarding wildfire smoke, we know little about how free‐ranging wildlife experience or respond to these exposures.

Distance, weather, and forage conditions drive timing of autumn migration in female mule deer

Movement Ecology
Background Seasonal migration is a behavioral strategy that animals evolved to exploit seasonally changing resources. Ungulates in northern temperate landscapes often seasonally migrate between low-elevation winter ranges and higher-elevation summer ...

Weather conditions associated with autumn migration by mule deer in Wyoming [PDF]

PeerJ, 2015
Maintaining ecological integrity necessitates a proactive approach of identifying and acquiring lands to conserve unfragmented landscapes, as well as evaluating existing mitigation strategies to increase connectivity in fragmented landscapes.

Back in the wild: where reintroduced California Condors spend their time

Ibis, EarlyView.
Captive breeding and reintroduction programmes have been instrumental in preventing the extinction of critically endangered species. As these efforts advance towards recovering self‐sustaining wild populations, understanding how reintroduced animals use space is essential for long‐term success.
