Noam Shtolz et al.
Human mitochondrial DNA (mtDNA) contains 13 protein-coding subunits of the oxidative phosphorylation pathway, 22 tRNA and two rRNA genes. However, accumulating evidence suggests that mtDNA encodes additional overlapping genetic elements, in...

The evolution of sexes is closely tied to uniparental inheritance (UPI) of mitochondrial DNA (mtDNA), where only females transmit mtDNA. Unlike nuclear DNA, mtDNA is highly polyploid and never evolved to be part of meiotic sex. Modelling sh...
Segregation of mtDNA mutations protects mitochondria across kingdoms, with impacts from longevity to agriculture and evolvability [0.03%]

Mitochondrial DNA (mtDNA) encodes essential bioenergetic and metabolic machinery across eukaryotes, but it is susceptible to mutational damage. The high copy number, physical location and inheritance patterns of mtDNA mean that specialist a...
Size-based competition explains large inter- and intra-individual variation in both intake and growth [0.03%]
基于大小的竞争解释了摄入量和生长量的较大个体间和个体内的变异
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%]
昼夜变化和脱钩的酸碱度-氧气动力学驱动了来自上升流海域的海带蟹的代谢可塑性
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...
Unpredictability and adaptive responses to dietary variability in Japanese quail [0.03%]

Gebrehaweria K Reda et al.
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%]
温度的自然变化驱动淡水鱼的热偏好，独立于感染状态之外
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%]
温度影响下加利福尼亚合唱蛙蝌蚪形态和生理特征的个体差异性

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...
Locomotor variation of fishes: connecting energetics and kinematic modulation [0.03%]
鱼类运动方式的变异：能效与运动模式调整之间的联系
Yangfan Zhang,Divya Ramesh,Hungtang Ko et al.
Yangfan Zhang et al.
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...
Exploring metabolism-growth relationships within and across individual fish [0.03%]
探究单个鱼体内及个体间的代谢与生长关系
Elizabeth C Hoots,Luis L Kuchenmüller,Peter A Biro et al.
Elizabeth C Hoots et al.
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...
