Geographic range size is predicted by plant mating system

Geographic range size is predicted by plant mating system.

Species' geographic ranges vary enormously, and even closest relatives may differ in range size by several orders of magnitude. With data from hundreds of species spanning 20 genera in 15 families, we show that plant species that autonomously reproduce via self-pollination consistently have larger geographic ranges than their close relatives that generally require two parents for reproduction. ...

No association between plant mating system & geographic range overlap

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...

A Geographic Information System Method for Estimating Home Range Size

\Ve developed a new technique to quantify home ranges by using coordinate-based data that were collected at srnall time intenals and entered into a Geographic Information System (GIS). We used this technique (digitized polygons [DP]) and 4 other established methods to estimate home range sizes of groups of black howler monkeys (Alorrana pigra). \Ve calculated the size of the area used by the st...

Experimental Pollinator Decline Affects Plant Reproduction and Is Mediated by Plant Mating System

There is growing concern that current pollinator decline will affect the reproduction of plant species, potentially driving a decline in plant population densities. We experimentally tested whether a reduction in flower visitation caused a reduction in fertilization rate in several species, and whether any reduction in fecundity of species depends on their degree of reproductive dependence on p...
