AbstractHow do large and small reptiles defend against infections, given the consequences of body mass for physiology and disease transmission? Functionally equivalent mammalian and avian granulocytes increased disproportionately with body ...

DNA Methylation and Counterdirectional Pigmentation Change following Immune Challenge in a Small Ectotherm [0.03%]
小变温动物在接受免疫挑战后出现DNA甲基化和反向色素变化
David R Tevs,Justin A Mukhalian,Emma Simpson et al.
David R Tevs et al.
AbstractBy allowing for increased absorption or reflectance of solar radiation, changes in pigmentation may assist ectotherms in responding to immune challenges by enabling a more precise regulation of behavioral fever or hypothermia. Varia...
IGF-1 Levels Increase during an Immune but Not an Oxidative Challenge in an Avian Model, the Japanese Quail [0.03%]
在日本鹌鹑模型中,IGF-1水平在免疫挑战期间升高但在氧化应激下不升高
Bibiana Montoya,Roxana Torres,América Hernández et al.
Bibiana Montoya et al.
AbstractInsulin-like growth factor 1 (IGF-1) is positively linked with growth and reproduction but negatively linked with survival, so a potential role of IGF-1 in modulating life history trade-offs has been proposed. However, the underlyin...
Infection Causes Trade-Offs between Development and Growth in Larval Amphibians [0.03%]
感染造成幼体两栖动物发育和生长的权衡

Marissa Wright et al.
AbstractTrade-offs between life history traits are context dependent; they vary depending on environment and life stage. Negative associations between development and growth often characterize larval life stages. Both growth and development...

Emma G W McKnight et al.
AbstractMorphological variation is sometimes used as an indicator of environmental stress in animals. Here, we assessed how multiple morphological traits covaried in Daphnia pulex exposed to five common forms of environmental stress (high t...
The Rate of Cooling during Torpor Entry Drives Torpor Patterns in a Small Marsupial [0.03%]
冬眠进入时的冷却速率驱动了小型有袋动物的冬眠模式
Chris B Wacker,Fritz Geiser
Chris B Wacker
AbstractTo maximize energy savings, entry into torpor should involve a fast reduction of metabolic rate and body temperature (Tb); that is, animals should thermoconform. However, animals often defend against the decrease in Tb via a tempora...
House Sparrows Vary Seasonally in Their Ability to Transmit West Nile Virus [0.03%]
季节变化影响House sparrows传输西尼罗河病毒的能力
Kyle K Koller,Meredith E Kernbach,Darrys Reese et al.
Kyle K Koller et al.
AbstractSeasonality in infectious disease prevalence is predominantly attributed to changes in exogenous risk factors. For vectored pathogens, high abundance, activity, and/or diversity of vectors can exacerbate disease risk for hosts. Conv...
Chronic Thermal Acclimation Effects on Critical Thermal Maxima (CTmax) and Oxidative Stress Differences in White Epaxial Muscle between Surface and Cave Morphotypes of the Mexican Cavefish (Astyanax mexicanus) [0.03%]
墨西哥盲鱼(Astyanax mexicanus)水面型和洞穴型白外侧肌临界热极限(CTmax)和氧化应激差异的慢性热习服效应

Ana Gabriela Jiménez
AbstractIn the face of increasing environmental temperatures, operative differences between mitochondrial function and whole-animal phenotypic response to the environment are underrepresented in research, especially in subtemperate ectother...
