Understanding value learning in animals is a key focus in cognitive neuroscience. Current models used in research are often simple, and while more complex models have been proposed, it remains unclear which assumptions align with actual val...

Back endurance is a strong predictor of back pain, but the mechanisms underlying this relationship are not clear. Fatigue reduces muscles' force-generating capacity, so greater fatigability may increase lumbar motion and loading and trunk m...

Avian brood parasites display enhanced annual fecundity compared to other passerine birds. Female brood parasitic brown-headed cowbirds (Molothrus ater) lay a staggering estimated 40-50 eggs/year. We examine how reproductive steroids mediat...

As tactile sensors, antennae must be flexible and responsive while maintaining shape and control of the structure. We evaluated the cricket antennae geometric and mechanical properties, which we treat as bending cantilever beams. Flexural r...

Integrating physiological research into environmental policy is crucial for addressing the complex challenges faced by ecosystems. Despite their potential, physiological insights are often underutilised in policy and management decisions, l...

Bumblebees rely on visual memories acquired during the first outbound flights to relocate their nest. While these learning flights have been extensively studied in sparse environments with few objects, little is known about how bees adapt t...

Animals have evolved complex auditory systems to extract acoustic information from natural environmental noise, yet they are challenged by rising levels of novel anthropogenic noise. Songbirds adjust their vocal production in response to in...

Air-breathing fish risk losing aerially sourced O2 to hypoxic water during branchial passage. Two adaptations thought to mitigate this loss are reduced gills and increased blood O2 affinity. Both are affected by temperature in the facultati...

Technological advancements now enable the use of flow-through respirometry for rapid, high-throughput metabolic phenotyping, though live-in systems currently do not exist for birds. We designed live-in respirometry chambers for small birds ...

Myostatin (MSTN) is a negative regulator of skeletal muscle development and growth in vertebrates, but its role in crustaceans remains debated. To explore the functional role of the MSTN (named EcMSTN) in Exopalaemon carinicauda and to faci...
