AbstractMigrating birds balance high energy expenditure required in flight with extended bouts of feeding at stopover to refuel, and strategies that permit birds to conserve energy during migration could benefit their overall performance. E...
Reassessing Hybrid Vigor or Hybrid Dysfunction Using Physiological Trade-Offs in an Endangered Salamander System [0.03%]
利用生理权衡方法重新评估濒危系统的杂种优势或杂种缺陷

AbstractFitness of interspecific hybrids can be higher or lower than that of their parental genotypes, with major ramifications for evolution and conservation. A recent study found that hybrid tiger salamanders had higher metabolic rates th...
Negative Effects of Excessive Heat on Colony Thermoregulation and Population Dynamics in Honeybees [0.03%]
过多热量对蜜蜂蜂群温度调节和种群动态的负面影响

Jun Chen et al.
AbstractHoneybees (Apis mellifera) are essential for the pollination and yield of many crops and have experienced significant mortality in recent years. While climatic warming has been suggested as a possible cause of honeybee losses, their...
Does the Evolution of Predatory Behavior Alter Stress Response? Insights from a Selection Experiment on Bank Voles [0.03%]
捕食行为的进化是否会改变压力反应？河岸鼠选择实验的启示

Gokul Bhaskaran et al.
AbstractThe ability to cope with challenging situations, such as the predator-prey interactions, can determine Darwinian fitness. While many studies are concerned with the stress response of prey facing a predator, the stress response of th...
Effects of Hemoglobin-O2 Affinity on Breathing and Gas Exchange in Deer Mice [0.03%]

AbstractEvolved increases in hemoglobin (Hb)-O2 affinity are common across high-altitude mammals and birds, but the downstream physiological effects of such increases remain poorly understood. In deer mice (Peromyscus maniculatus), the gene...
Sclerotization Protects Drosophila nigrospiracula against Parasitism by Ectoparasitic Mites [0.03%]

AbstractClutch size variation may be adaptive in bird populations if parents lay a clutch size that maximizes offspring recruitment. Brood size manipulation experiments allow for testing the optimization of clutch size by studying the effec...
Honesty Is Costly in a Deceptive System: Locomotor Costs of Producing Large and Strong Weapons for the Crayfish Cherax destructor [0.03%]
欺骗系统中的诚实是有代价的：拟沼蝉 Cherax destructor 大而强武器的运动成本

AbstractTheory predicts that signals of strength should reliably reflect an individual's fighting ability, with the costs of producing and/or displaying high-quality signals maintaining their reliability. Crustaceans offer a unique system t...
Prior Infection Induces Long-Lasting Partial Immunity to Reduce Transmission within Flocks in an Avian Host-Pathogen System [0.03%]
前期感染诱导出持久的免疫反应以减少家禽中的传播：一种鸟类宿主-病原系统案例
Madeline C Sudnick,Erin L Sauer,Sarah E DuRant

AbstractPopulation-level differences in the ability to maintain immunity can lead to contrasting survival outcomes between groups and determine how future outbreaks will spread. Pathology and infectiousness during subsequent infections can ...
Short-Term Telomere Elongation in Breeding Adults of a Long-Lived Seabird [0.03%]
长寿命海鸟繁殖个体的端粒短期延长现象

Mauricio Guillen-Parra et al.
AbstractTelomere dynamics have been linked to differences in reproductive effort across vertebrates. In the Cocos booby (Sula brewsteri), we predicted that parents' telomeres would shorten according to their breeding effort during incubatio...
