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 and Metabolic Intraspecific Biodiversity of Ganoderma lucidum
Fourteen Ganoderma lucidum strains from different geographic regions were identified using ITS region sequencing. Based on the sequences obtained, the genomic relationship between the analyzed strains was determined. All G. lucidum strains were also genetically characterized using the AFLP technique. G. lucidum strains included in the analysis displayed an AFLP profile similarity level in the r...
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...
متن کاملPomegranate: Biodiversity and genetic resources, a review
Pomegranate (Punica granatum L.) is a multipurpose plant that is important as nutrition, medical, horticulture, landscape and environment. The plant has been cultivated since old Iran and Egypt which is mentioned in Bible and Quran. Origin of the plant is Iran and some neighbour countries, although it is cultivated in many countries, now a day. Botanically, it is classified in Punicaceae and ha...
