Variations can be classified as occurring at individual, intraspecific
, and interpopulational levels (Webb 1996).
pollen mediated gene flow rates declined from 0.44 to 0.01% over a distance of 100 m from the pollinator in 2000 (Table 2).
COMPETITION (SCRAMBLE AND CONTEST); POPULATION SUSTAINABILITY DEPENDS ON DIVERSITY OR INEQUALITY
marginata was dramatically reduced by previous feeding, both intraspecific
feeding and interspecific feeding by P.
- Some of the earliest ecological theory was built on a clear understanding of the importance of both inter- and intraspecific
competition as well as predation (Gause 1934).
For the three most common species at each site, data were obtained on the sizes and interplant distances of individuals of all possible intraspecific
and interspecific pair combinations.
Although data from a less rapidly evolving gene may ultimately resolve relationships among the COI clades, it is clear that none of the relevant nodes is substantially deeper than the others, as would be expected if the biogeographic boundary had a pronounced effect on intraspecific
In the field experiment, we found no evidence of intraspecific
predation; all pupae were accounted for and intact.
variation in body size and fecundity in insects: a general relationship.
For analysis of phylogeographic and demographic patterns of intraspecific
divergence, we gathered data from both nuclear (microsatellite) and mitochondrial sources.
The lower intraspecific
variations occurred in the species C.
However, a few studies have been conducted to evaluate intraspecific
variation within F.
