WebJan 11, 2024 · fluctuating asymmetry. Morphological traits reflecting body size are often assessed in selection studies (Kingsolver et al., 2001; Kingsolver & Pfennig, 2004). Body size is one of the most important quantitative traits of an organism, as it strongly affects most physiological and fitness traits (Calder, 1984; Schmidt-Nielsen, 1984; Roff, 1992)

WebThis study provides evidence to corroborate the hypothesis that asymmetry partly reflects DI and is correlated with a reduction in fitness measured by survival and reproduction in bats. We studied two colonies of the bat Carollia perspicillata in southeastern Brazil over 5 years, marking and recapturing individuals. WebNational Center for Biotechnology Information
WebAug 7, 2024 · Slower reaction time is a measure of cognitive decline and can occur as early as 24 years of age. We are interested if developmental stability predicts cognitive performance independent of age and lifestyle (e.g., diet and exercise). Developmental stability is the latent capacity to buffer ontogenetic stressors and is measured by low … WebApr 10, 2024 · Fluctuating asymmetry can be a response to both environmental and genetic stress, with genetic stress representing the natural susceptibility condition of organisms leading to fluctuating asymmetry. In contrast, environmental stress represents the pressure exerted by the environment in which organisms develop (Naugler & …
WebThis work is one of the first to use FA to address environmental stress caused by habitat loss in small mammal populations from a Neotropical biome and suggests that shape FA might serve as a conservation tool to monitor human impact on natural animal populations.
