Gryllus firmus; climate change; dimorphism; environmental factors; fecundity; females; food availability; heat; insects; life history; locomotion; metabolism
Abstract:
... Many environmental stressors naturally covary, and the frequency and duration of stressors such as heat waves and droughts are increasing globally with climate change. Multiple stressors may have additive or non-additive effects on fitness-related traits, such as locomotion, reproduction, and somatic growth. Despite its importance to terrestrial animals, water availability is rarely incorporated i ...

Drosophila serrata; dimorphism; evolutionary biology; females; genotype-environment interaction; longevity; males; population density; social environment
Abstract:
... Sex differences in lifespan remain an intriguing puzzle in evolutionary biology. While explanations range from sex differences in selection to sex differences in the expression of recessive lifespan‐altering mutations (via X‐linkage), little consensus has been reached. One unresolved issue is the extent to which genetic influences on lifespan dimorphism are modulated by the environment. For exampl ...

Abstract:
... Tongue sole is an economically important marine flatfish with significant sexual growth dimorphism that female with superior growth performance, and phenotypic female proportion (FP) is rather low (10%–30%) under rearing conditions. Knowledge of whether genetic variation exists for FP is needed for determining the feasibility of including this desirable trait into breeding goal in tongue sole. The ...

Abstract:
... Sex dimorphism is a common phenomenon in animals. Blotched snakehead (Channa maculata) is an economically important freshwater fish with a faster growth rate in males. However, existing sex-specific markers were too few and difficult to use in production practice, which hindered the development of all-male breeding. Here, we generated 15.64, 20.77 and 29.03 Gb paired-end genomic sequence reads for ...

Abstract:
... Egg laying is one of the most important phases in a female bird's breeding cycle. Its cost is high because eggs contain all the resources needed for the development of an embryo. Variation in size and quality of eggs can have important long‐term consequences for offspring survival. Hatching asynchrony is known to influence sibling competition in many bird species. Last‐hatched chicks will have a c ...

Here, I show that female plants of the dioecious mistletoe Misodendrum quadrifolium (Misodendraceae) grow larger than male plants. Correspondingly, females reduce the photosynthetic capacity of infected host branches more than males. Results ind ...
