Cooling requirements fueled the collapse of a desert bird community from climate change. [PDF]

open access: yes, 2019
Climate change threatens global biodiversity by increasing extinction risk, yet few studies have uncovered a physiological basis of climate-driven species declines.

Wild‐Derived House Mice (Mus musculus) Are Able to Cope With a Constant Light Environment

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Exposure to altered nighttime lighting conditions has become common in today's modern world. Light at night disrupts circadian processes that govern feeding patterns, sleep/wake cycles, and metabolic homoeostasis, increasing the risk of developing pathologies associated with cardiometabolic disease. Yet, the underlying mechanism(s) responsible

Raman Signature of the Wings of the Globe Skimmer Dragonfly: Pantala flavescens

open access: yesJournal of Raman Spectroscopy, EarlyView.
Raman spectroscopy is used to confirm the presence of aliphatic and aromatic hydrocarbons and related derivatives including aldehydes, halides, alcohols, acids, esters, and phenols on the wings of Pantala flavescens. The analysis indicates that wing‐surface lipid composition is largely consistent across the three main ecological zones in Ghana. Notably,

Addressing biases in sliding window analysis gives new insight into the response of parturition date to weather in a wild mammal

open access: yesOikos, EarlyView.
Animal breeding phenology in temperate and high latitude regions is often predicted by weather variables, such as temperature. Much work on this topic has focused on taxonomic groups that employ adaptive plastic responses to annual variation in an environmental cue, with analytical approaches developed to determine when weather has an effect and the ...

The influence of micro-scale thermal habitat on the movements of juvenile white sharks in their Southern California aggregation sites

open access: yesFrontiers in Marine Science
While juvenile white sharks (JWS) can display regional endothermy, the need to maintain internal temperatures within an energetically favorable range likely drives thermoregulatory movements to maximize growth and foraging efficiency.

Nutritional effects on the expression of cryptic pigmentation in freshwater isopods

open access: yesOikos, EarlyView.
Cryptic pigmentation is a key phenotypic adaptation that helps many benthic invertebrates evade visual predators. However, little is known about whether and how the expression of pigmentation phenotypes that match the habitat background is influenced by the availability of nutritional resources.
