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.

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.

Apex predators exploit advantageous snow conditions across hunting modes

Journal of Animal Ecology, EarlyView.
Advantageous snow conditions—in terms of snow depth and density—are among the most important features of the winter landscape for two apex predators, regardless of hunting strategy. In a warming climate, the knock‐on effects of a diminishing snowpack may reduce the hunting success of multiple large carnivore species.

Predicting disease spread from host movement data: Chronic wasting disease in North America as a case study

Journal of Animal Ecology, EarlyView.
This paper estimates the rate of chronic wasting disease spread in multiple regions and compares these rates with model predictions based on deer movement data. Abstract Rare long‐distance movements can increase the spatial spread of invasive species and shifts in species ranges. For wildlife disease spread, however, seasonal migrations may only matter

Understanding natal emigration in group‐living carnivores

Journal of Animal Ecology, EarlyView.
Dispersal is a key ecological and evolutionary process, yet drivers of variation in emigration under human‐modified conditions remain understudied. Using a novel genetic approach applied to harvested grey wolves in Idaho, USA, we found that prey availability and population density shape natal emigration patterns in a cooperative breeder.

Biological consequences of winter‐feeding of mule deer in developed landscapes in Northern Utah

Wildlife Society Bulletin, 2011
Winter‐feeding of mule deer (Odocoileus hemionus) in developed landscapes is often advocated by stakeholders to compensate for lost or fragmented winter range.

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 ...

Landscape conservation forecasting to evaluate ecological condition and wildlife habitat suitability in eastern Nevada U.S.A.

Restoration Ecology, EarlyView.
Abstract Introduction Cooperation among managers of protected areas and federal multiple use lands with private inholdings to increase restoration success and economies of scale creates ecological and regulatory complexity best studied with state‐and‐transition simulation models (STSM).

Balancing Current and Future Reproductive Investment: Variation in Resource Selection During Stages of Reproduction in a Long-Lived Herbivore

Frontiers in Ecology and Evolution, 2020
Large herbivores exhibit relatively slow-paced life histories, and allocate resources toward maintaining high rates of adult survival, while juvenile survival has greater variability. Maternal females make decisions throughout life stages of reproduction

Seasonal variation in wind speed and oceanic salt spray favors delayed reproduction in coastal yellow monkeyflowers

American Journal of Botany, Volume 113, Issue 8, August 2026.
Abstract Premise The optimal timing of reproduction depends on the relative risk and benefit of continued growth. These risks and benefits depend on the local environment, which varies seasonally. While temperature and water availability are well‐studied selective agents on reproductive timing, less is known about other seasonally variable factors ...
