Spatial and temporal patterns of parthenogenesis and parasitism in the freshwater snail Melanoides tuberculata.

abstract：:When two species come into contact and interbreed, the production of unfit hybrids can limit or prevent gene flow between the populations, thus maintaining each species' separate identity. The genetic basis of this hybrid dysfunction has recently begun to be elucidated, particularly for hybrid sterility and inviabilit...

In birds, body size of nestlings and the number of nestlings produced (brood size) have occasionally been shown to be constrained by higher predation on larger nestlings and tho...
