The effect of heterospecific pollen receipt on fruit and seed set may depend in part on the breeding system of the recipient species.
In this report, we test the reinforcement hypothesis by comparing heterospecific gamete compatibility in M.
Additionally, density of heterospecific prey may be an important stimulus.
Pure conspecific and heterospecific pollinations were performed on flowers of both I.
Figure 1 shows the AFLP fingerprint of conspecific and heterospecific crosses generated by using the primer combination E-AGC x MCTT.
Though uncommon, studies of developmental patterns of heterospecific cross-fostered birds may be particularly helpful in elucidating differences in reproductive life history strategies among similar species, and the plasticity of developmental traits when reared under different conditions (Slagsvold, 2004).
An interesting but often neglected question is, what is the relationship between conspecific alarm signals and heterospecific antipredator compounds released in the same secretion?
Positive association" is similarly defined, but involves an excess rather than a deficit of heterospecific neighbors.
These criteria include demonstrating that heterospecific matings occur or once occurred in nature; hybrids are produced and selected against in the wild (reduced, but nonzero hybrid fitness); variation is heritable and capable of responding to selection; and the displacement has not occurred as a byproduct of other processes causing divergence in sympatry (Howard 1993).
A genetic map on the Mimulus guttatus species complex reveals transmission ratio distortion due to heterospecific interactions.
Although adults of most broadcast-spawning marine invertebrates lack mating behaviors that contribute to reproductive isolation in copulating taxa such as insects, the interactions of gametes can limit heterospecific fertilization.
Researchers decided to study this heterospecific sexual behavior between a primate and a non- primate species.
