Intraspecific variation and species coexistence.
We use a two-species model of plant competition to explore the effect of intraspecific variation on community dynamics. The competitive ability ("performance") of each individual is assigned by an independent random draw from a species-specific probability distribution. If the density of individuals competing for open space is high (e.g., because fecundity is high), species with high maximum (o...
متن کاملInter- and intraspecific genetic and morphological variation in a sibling pair of carabid species
BACKGROUND Pogonus littoralis and Pogonus chalceus are very close related species with quite different ecological preferences within salt marshes. We study the evolutionary processes in and between these presumably young species. Therefore, we compare the variation in ecologically relevant characters and the genetic variation within one of the species (intraspecific differentiation) with the va...
متن کاملAssessment of microsatellites in estimating inter- and intraspecific variation among Neotropical Crocodylus species.
We tested microsatellites that were developed for the saltwater crocodile (Crocodylus porosus) for cross-species amplification and to provide an estimate of inter- and intraspecific variation among four species of Neotropical crocodiles (C. rhombifer, C. intermedius, C. acutus, and C. moreletii). Our results indicated that with the exception of 2 loci in C. intermedius, all 10 microsatellite lo...
متن کاملUse of RAPD and AFLP markers to identify inter- and intraspecific hybrids of Mentha.
Three controlled crosses were carried out involving Mentha arvensis and Mentha spicata [M. spicata CIMAP/C30 x M. spicata CIMAP/C33 (cv. Neera); M. arvensis CIMAP/C18 x CIMAP/C17 (cv. Kalka); and M. arvensis CIMAP/C17 x M. spicata CIMAP/C33]. The parents were subjected to random amplified polymorphic DNA (RAPD) analysis with 80 primers, and polymorphic primers were tested for detecting coinheri...
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...
