The singing phenology of Bachman's sparrow: implications for monitoring programs

Wildlife Society Bulletin, EarlyView.
We used automated recording units, weather data, and multiple logistic regression with generalized estimating equations to determine the annual singing period and influences on singing behavior of Bachman's sparrow in Texas, USA, surveying daily for 2 years.

Fecal Glucocorticoid and Androgen Metabolites in Eastern Gray Kangaroos (Macropus giganteus) Following Environmental Relocation

Zoo Biology, EarlyView.
Fecal glucocorticoid (GCM) and androgen metabolite (AM) concentrations were monitored for 3 months following the relocation of three eastern gray kangaroos (Macropus giganteus) between zoological facilities. Both metabolites showed high concentrations during the early postrelocation period, followed by a rapid decline and stabilization, suggesting ...

Increased energetic cost of movement reduces reproductive output in zebrafish at different temperatures and water flow rates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Locomotion consumes a large proportion of individual energy budgets and may impose energetic constraints on other fitness‐related traits particularly under variable environmental conditions.

Life history attributes influencing metabolic variation in an estuarine fish

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Considering that energy availability and oxygen transport potential are limited in supplying metabolic requirements, all animals face trade‐offs between competing metabolic demands.

Male production in green sea turtles under a feminizing climate: A validated model of sex ratios with temperature‐dependent sex determination

Journal of Animal Ecology, EarlyView.
This study introduces validated methods to predict sex ratios in wild Green sea turtle (Chelonia mydas) nests. It quantifies beach‐scale temperature heterogeneity, incorporates clutch‐level variation in thermal sensitivity and models temperature effects across the thermosensitive period, demonstrating how temporal temperature dynamics and spatial ...
