No association between plant mating system and geographic range overlap.
PREMISE OF THE STUDY Automatic self-fertilization may influence the geography of speciation, promote reproductive isolation between incipient species, and lead to ecological differentiation. As such, selfing taxa are predicted to co-occur more often with their closest relatives than are outcrossing taxa. Despite suggestions that this pattern may be general, the extent to which mating system inf...
متن کاملEffects of range-wide variation in climate and isolation on floral traits and reproductive output of Clarkia pulchella.
PREMISE OF THE STUDY Plant mating systems and geographic range limits are conceptually linked by shared underlying drivers, including landscape-level heterogeneity in climate and in species' abundance. Studies of how geography and climate interact to affect plant traits that influence mating system and population dynamics can lend insight to ecological and evolutionary processes shaping ranges....
متن کاملSpeciation via species interactions: the divergence of mating traits within species.
A species may overlap with a mosaic of species across its geographic range. Many types of species interaction cause selection on mating traits, but their role in generating within-species divergence has been neglected. The pattern of reproductive character displacement (RCD) has been classically attributed to reinforcement, a process driven by selection against hybridisation. Recent reinforceme...
متن کاملFeasibility Study of Using Geographic Data and Information System in Official Statistics (Case Study: Industrial Site Selection in Ardabil Province)
Abstract. The appropriate site selection for the establishment of industries pays attention to a wide range of criteria and combines economic and social benefits with the application of multi-criteria decision making in the environment of the environmental system. It also Ardabil province has a high investment capacity in industrial sectors in terms of site selection investment projects. This ...
متن کاملMating-system variation, demographic history and patterns of nucleotide diversity in the Tristylous plant Eichhornia paniculata.
Inbreeding in highly selfing populations reduces effective size and, combined with demographic conditions associated with selfing, this can erode genetic diversity and increase population differentiation. Here we investigate the role that variation in mating patterns and demographic history play in shaping the distribution of nucleotide variation within and among populations of the annual neotr...
