Low interspecific variation and no phylogenetic signal in additive genetic variance in wild bird and mammal populations [PDF]

open access: yesEcology and Evolution, 2023
Evolutionary adaptation through genetic change requires genetic variation and is a key mechanism enabling species to persist in changing environments. Although a substantial body of work has focused on understanding how and why additive genetic variance (

Interspecific variation in cooperative burrowing behavior by Peromyscus mice [PDF]

open access: yesEvolution Letters, 2022
Animals often adjust their behavior according to social context, but the capacity for such behavioral flexibility can vary among species. Here, we test for interspecific variation in behavioral flexibility by comparing burrowing behavior across three ...

Responses of Intraspecific and Interspecific Trait Variations to Nitrogen Addition in a Tibetan Alpine Meadow

open access: yesPlants
A community functional structure may respond to environmental changes such as nitrogen (N) enrichment by altering intraspecific and interspecific trait variations.

Differential water mite parasitism, phenoloxidase activity, and resistance to mites are unrelated across pairs of related damselfly species. [PDF]

open access: yesPLoS ONE, 2015
Related host species often demonstrate differences in prevalence and/or intensity of infection by particular parasite species, as well as different levels of resistance to those parasites.

Variation and association of leaf traits for desert plants in the arid area, northwest China

open access: yesEcology and Evolution, 2023
Characterizing variation and association of plant traits is critical for understanding plant adaptation strategies and community assembly mechanisms. However, little is known about the leaf trait variations of desert plants and their association with ...

Highly Evolvable: Investigating Interspecific and Intraspecific Venom Variation in Taipans (Oxyuranus spp.) and Brown Snakes (Pseudonaja spp.)

open access: yesToxins, 2023
Snake venoms are complex mixtures of toxins that differ on interspecific (between species) and intraspecific (within species) levels. Whether venom variation within a group of closely related species is explained by the presence, absence and/or relative ...

Larval anurans follow predictions of stoichiometric theory: implications for nutrient storage in wetlands

open access: yesEcosphere, 2021
Ecological stoichiometry provides a framework to predict how animals regulate nutritional balances within their tissue and, as a result, how animal biomass affects ecosystem processes through nutrient cycling.

Structure analysis of the ribosomal intergenic spacer region of Phaeoacremonium italicum as a study model

open access: yesPhytopathologia Mediterranea, 2021
Increasing recognition of novel Phaeoacremonium species, and their recent taxonomic reassignment through phylogeny based on the β-tubulin and actin genes, have highlighted the presence of paraphyly, intraspecific variation, and incongruence of some ...

Synchronous population dynamics in California butterflies explained by climatic forcing [PDF]

open access: yesRoyal Society Open Science, 2017
A long-standing challenge for population biology has been to understand why some species are characterized by populations that fluctuate in size independently, while populations of other species fluctuate synchronously across space.
