No evidence that shrinking and shapeshifting meaningfully affect how birds respond to warming and cooling

The paper shows that shrinking and shape-shifting in birds do not provide thermoregulatory benefits in a warming world, using experimental data on Japanese quail.

Thermoregulatory consequences of growing up during a heatwave or a cold snap

The study examines if early-life thermal exposure affects thermoregulatory traits in adulthood in Japanese quail, finding no lasting effects from heatwave or cold snap conditions.

Seasonal and environmental factors contribute to the variation in the gut microbiome: a large-scale study of a small bird

This study examines seasonal and environmental factors influencing gut microbiome variation in wild great tits across their range, finding higher diversity in winter and some habitat-related differences.

Using metabolic data to uncover the ontogeny of endothermy in an altricial bird

This study investigates the ontogeny of endothermy in nestling blue tits, finding no effect of brood size on heat production development but highlighting early metabolic capabilities.

Permeabilization status affects the relationship between basal metabolic rate and mitochondrial respiration in great tit blood cells

How do fluctuating temperatures alter the cost of development?

This study examines how fluctuating temperatures affect the cost of development in common wall lizards, finding that higher temperature variance increases energy expenditure and reduces residual yolk reserves.

Population divergence in maternal investment and embryo energy use and allocation reveals adaptive responses to cool climates

This study examines how wall lizards adapt to cool climates by analyzing maternal investment and embryo energy use and allocation across altitudinal regions.

Plasticity of mitochondrial function safeguards phosphorylating respiration during in vitro simulation of rest-phase hypothermia

The paper investigates how mitochondrial function adapts during simulated rest-phase hypothermia in great tits, finding that phosphorylating respiration remains stable while leak respiration decreases, preserving ATP production.

A whole blood approach improves speed and accuracy when measuring mitochondrial respiration in avian hematocytes

This study develops a whole blood protocol for measuring mitochondrial respiration in birds, showing it is faster, more reproducible, and more physiologically relevant than isolated cell measurements.

Ambient temperature effects on stress-induced hyperthermia in Svalbard ptarmigan

This study examines how ambient temperature affects stress-induced hyperthermia in Svalbard ptarmigan during handling in winter and spring.

Kinetic analysis methods applied to single motor protein trajectories

The paper introduces two new statistical methods to analyze single motor protein trajectories and extract kinetic parameters from both simulated and experimental data.
