Pairing patterns and fitness in a free-ranging population of pinyon jays: What do they reveal about mate choice. [PDF]

, 1988
Pairing in 141 pairs of Pinyon Jays (Gymnorhinus cyanocephalus ) was assortative for age, but was random for bill length and body weight. Assortative pairing for age may be favored because similar-aged partners produced slightly more young than ...

Space Use and Movements During Egg Laying Associated With Nest Fate and Female Survival in Eastern Wild Turkeys

Ecology and Evolution, Volume 16, Issue 2, February 2026.
We assessed behaviors of female wild turkeys during the laying period and evaluated impacts of those behaviors on nest success and female survival. We found that increased movements during laying resulted in a decreased probability of nest success but an increased probability of female survival during incubation.

Seasonal regulation of melanogenesis in ptarmigan [PDF]

, 2023
Ptarmigan are one of the few animals, and only bird species, to undergo seasonal colour change. Every year they moult between a white winter morph and brown summer and autumn morphs and back again.

Supporting dryland restoration success with applied ecological forecasting of seeding outcomes

Restoration Ecology, Volume 34, Issue 2, February 2026.
Abstract Introduction Ecological restoration is increasingly used to sustain biodiversity and ecosystem services. In drylands of the western United States (US), post‐disturbance restoration often involves seeding treatments to promote the recovery of native plant communities. Spatial and temporal variability in environmental conditions influences plant

Plant Driven Movement: Does Plant Quality Affect the Foraging Patterns of Successful Male Sage-Grouse (Centrocercus Urophasianus)? [PDF]

, 2015
The structural and dietary quality of plants is highly variable across the landscape and may influence energy acquisition by herbivores needed for energy dependent activities.

Fine-scale genetic structure among greater sage-grouse leks in central Nevada [PDF]

, 2016
BACKGROUND: Mating systems that reduce dispersal and lead to non-random mating might increase the potential for genetic structure to arise at fine geographic scales.

Identifying climate‐change refugia for species management and conservation in the Pacific Northwest

Conservation Science and Practice, Volume 8, Issue 1, January 2026.
Abstract The impacts of climate change are already affecting many species and habitats, presenting challenges for species management and conservation. Protecting climate refugia—areas buffered from climate shifts where species can persist despite broader changes—has been proposed as a tool for managing species under climate change.

Greater Sage-Grouse and Community Responses to Strategies to Mitigate Environmental Resistance in an Anthropogenic Altered Sagebrush Landscape [PDF]

, 2021
Sagebrush (Artemisia spp.) ecosystems are diverse habitats found throughout western North America. Anthropogenic disturbances has resulted in the loss of over half of the sagebrush ecosystems impacting sagebrush obligate species such as sage-grouse ...

Landscape features and seasonal habitat predict lek site selection and lek size of a Tympanuchus grouse

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract The lek hotspot hypothesis predicts that leks will form in areas where males are more likely to encounter females, providing wildlife managers with a framework supporting the use of leks as the focus for prairie and shrubland grouse conservation and monitoring.

Comparison of methods for estimating wild turkey poult survival

Wildlife Society Bulletin, Volume 49, Issue S1, December 2025.
Wild turkey poult survival is a challenging metric to measure in wild turkey reproduction, and interpreting this information can have significant implications for managers at the population scale. Flushing wild turkey broods and radio‐tagging poults produced similar estimates of poult survival over a 56‐day monitoring period post‐hatching. Both methods
