Sensitivity of Self-Organized Speciation to Long- Distance Dispersal
Previous work has shown that speciation can result from the self-organized accumulation of multiple mildly underdominant (nearly neutral) loci in a continuous population, when mating is spatially localized. In contrast, when mating is panmictic, underdominance is quickly eliminated and the population always converges on a single genotype, as predicted by mean-field approximations. The focus of ...
متن کاملLong-Distance Dispersal of Fungi.
Dispersal is a fundamental biological process, operating at multiple temporal and spatial scales. Despite an increasing understanding of fungal biodiversity, most research on fungal dispersal focuses on only a small fraction of species. Thus, any discussion of the dispersal dynamics of fungi as a whole is problematic. While abundant morphological and biogeographic data are available for hundred...
متن کاملLong-distance dispersal of plants.
Long-distance dispersal (LDD) of plants poses challenges to research because it involves rare events driven by complex and highly stochastic processes. The current surge of renewed interest in LDD, motivated by growing recognition of its critical importance for natural populations and communities and for humanity, promises an improved, quantitatively derived understanding of LDD. To gain deep i...
متن کاملExplaining long-distance dispersal: effects of dispersal distance on survival and growth in a stream salamander.
Long-distance dispersal (LDD) may contribute disproportionately to range expansions, the creation of new evolutionary lineages, and species persistence in human-dominated landscapes. However, because data on the individual consequences of dispersal distance are extremely limited, we have little insight on how LDD is maintained in natural populations. I used six years of spatially explicit captu...
متن کاملMeasuring short distance dispersal of Alliaria petiolata and determining potential long distance dispersal mechanisms
Introduction Alliaria petiolata, an herbaceous plant, has invaded woodlands in North America. Its ecology has been thoroughly studied, but an overlooked aspect of its biology is seed dispersal distances and mechanisms. We measured seed dispersal distances in the field and tested if epizoochory is a potential mechanism for long-distance seed dispersal. Methods Dispersal distances were measured...
