Importance of Genetic–Fitness Correlations for the Conservation of Amphibians [PDF]
Animals, 2023 Endangered animals suffer from isolation of their habitats. Isolation leads to a reduction in population size as well as a decrease in genetic diversity and a concomitant increase in the risk of extinction.

Global Amphibian Declines, Loss of Genetic Diversity and Fitness: A Review
Diversity, 2010 It is well established that a decrease in genetic variation can lead to reduced fitness and lack of adaptability to a changing environment. Amphibians are declining on a global scale, and we present a four-point argument as to why this taxonomic group ...

Sex-specific dominance reversal of genetic variation for fitness
PLoS Biology, 2018 The maintenance of genetic variance in fitness represents one of the most longstanding enigmas in evolutionary biology. Sexually antagonistic (SA) selection may contribute substantially to maintaining genetic variance in fitness by maintaining ...

The genetics of physical fitness [PDF]
British Journal of Sports Medicine, 2000 Editor,—Might I briefly comment on Dr Lavin's observation that elite athletes, whom he classes as “freak”, “are as removed from real life as it is possible to …

Fitness Determinants of Influenza A Viruses
Viruses, 2023 Influenza A (IAV) is a major human respiratory pathogen that causes illness, hospitalizations, and mortality annually worldwide. IAV is also a zoonotic pathogen with a multitude of hosts, allowing for interspecies transmission, reassortment events, and ...

A GENETIC ALGORITHM FOR FACE FITTING [PDF]
Proceedings of the International Conference on Computer Graphics Theory and Applications, 2012 Accurate estimation of the shape of human faces has many applications from the movie industry to psychological research. One well known method is to fit a Three Dimensional Morphable Model to a target image. This method is attractive as the faces it constructs are already projected onto an orthogonal basis making further manipulation and analysis ...

Potential fitness for genetic programming [PDF]
Proceedings of the 10th annual conference companion on Genetic and evolutionary computation, 2008 We introduce potential fitness, a variant of fitness function that operates in the space of schemata and is applicable to tree-based genetic programing. The proposed evaluation algorithm estimates the maximum possible gain in fitness of an individual's direct offspring. The value of the potential fitness is calculated by analyzing the context semantics

The intersexual genetic correlation for lifetime fitness in the wild and its implications for sexual selection. [PDF]
PLoS ONE, 2007 BACKGROUND: The genetic benefits of mate choice are limited by the degree to which male and female fitness are genetically correlated. If the intersexual correlation for fitness is small or negative, choosing a highly fit mate does not necessarily result
