Biodiversity and intraspecific genetic variation
Biodiversity is mostly discussed at the level of species, but genetic variation within species may be as important as variation between species. It enables organisms to adapt to environmental changes. The requirement for genetic variation differs however widely between species and groups of species. Animal species at the top of the food web, such as large carnivorous mammals, tend to have a rem...
متن کاملGenetic, geographic, and environmental correlates of human temporal bone variation.
Temporal bone shape has been shown to reflect molecular phylogenetic relationships among hominoids and offers significant morphological detail for distinguishing taxa. Although it is generally accepted that temporal bone shape, like other aspects of morphology, has an underlying genetic component, the relative influence of genetic and environmental factors is unclear. To determine the impact of...
متن کاملGenetic analysis of environmental variation.
Environmental variation (VE) in a quantitative trait - variation in phenotype that cannot be explained by genetic variation or identifiable genetic differences - can be regarded as being under some degree of genetic control. Such variation may be either between repeated expressions of the same trait within individuals (e.g. for bilateral traits), in the phenotype of different individuals, where...
متن کاملIntraspecific genetic variation and species coexistence in plant communities.
Many studies report that intraspecific genetic variation in plants can affect community composition and coexistence. However, less is known about which traits are responsible and the mechanisms by which variation in these traits affect the associated community. Focusing on plant-plant interactions, we review empirical studies exemplifying how intraspecific genetic variation in functional traits...
متن کاملIntraspecific genetic variation and competition interact to influence niche expansion.
Theory and empirical evidence show that intraspecific competition can drive selection favouring the use of novel resources (i.e. niche expansion). The evolutionary response to such selection depends on genetic variation for resource use. However, while genetic variation might facilitate niche expansion, genetically diverse groups may also experience weaker competition, reducing density-dependen...
