Size-based competition explains large inter- and intra-individual variation in both intake and growth [0.03%]
Alexandra S Johne,Shane A Richards,Chris G Carter et al.
Alexandra S Johne et al.
Size-based intraspecific competition can lead to high variation in both feed intake and growth. However, isolating the effects of competition on fish physiology and growth from other environmental factors is challenging. To address this, we...
Diel variability and decoupled pH-oxygen dynamics drive metabolic plasticity in kelp crabs from an upwelling seascape [0.03%]
Cristian A Vargas,Karen Garces,L Antonio Cuevas et al.
Cristian A Vargas et al.
Coastal upwelling zones, shaped by global change and human impacts, naturally impose hypoxia and acidification on marine species, creating selective pressures that influence physiological responses and drive phenotypic variability. Understa...

Understanding animals' molecular mechanisms of adaptation to unpredictable changes in dietary availability provides insights into how organisms optimize resource utilization and ensure survival under such conditions. The mechanistic target ...
Natural variation in temperature drives thermal preference in a freshwater fish, independent of infection status [0.03%]
Marie Levet,Shaun S Killen,Maryane Gradito et al.
Marie Levet et al.
Aquatic environments are often thermally variable, and ectotherms may select thermal habitats based on their physiological state. However, it remains unclear whether immune reactions and sickness behaviours, including behavioural fever or c...
Temperature influences inter-individual variability in morphological and physiological traits of Baja California chorus frog tadpoles [0.03%]

Inter-individual variability is the range of phenotypes within a population and can shape adaptive responses to environmental change. However, how temperature influences this variability remains unclear despite its importance for predicting...

Analyses of vertebrate locomotion have frequently revealed variations in locomotor energetics and movement both among individuals and through time within an individual. This variation is often collapsed into mean values for broad comparativ...

Differences in growth rate and metabolism between individual animals can influence survival, reproduction and competitive social dynamics during vulnerable life stages. Acknowledging this, among-individual variability has received growing r...
Temperature and predation alter metabolic scaling without changing the size-based community structure of freshwater macroinvertebrates [0.03%]
Vojsava Gjoni,Douglas Stewart Glazier,Justin P F Pomeranz et al.
Vojsava Gjoni et al.
Body size is a key trait that influences ecological processes such as metabolism, abundance and species interactions. While the metabolic theory of ecology (MTE) proposes a universal scaling of metabolic rate with body mass, recent evidence...
'Variation ... a central attribute of living systems': patterns and implications of variability in the development of molluscan heart function [0.03%]
Oliver Tills,Ziad Ibbini,Simon Rundle et al.
Oliver Tills et al.
Diversity in the ontogeny of physiological systems is a central, too often overlooked tenet of biodiversity. Here, we use intensive screening of the development of heart function in embryos of the gastropod Radix balthica to investigate (i)...
Thermal variability: how realistic temperature fluctuations alter physiological performance in intertidal mussels [0.03%]
Michael T Nishizaki,Sara Leuchtenberger,Wanying Na et al.
Michael T Nishizaki et al.
Understanding how fluctuating temperatures impact ectothermic physiological performance is critical for predicting species' responses to climate change. Many laboratory studies use simplified thermal designs that typically alternate between...
