The accuracy of gene flow estimates is unknown in most natural populations because direct
estimates of dispersal are often not possible. These estimates can be highly imprecise or …

Selfing, the fusion of male and female gametes from a single genetic individual or colony, is
possible in many plants and also in hermaphrodite animals. We review the occurrence of …

This document introduces the viable salmonid population (VSP) concept, identifies VSP
attributes, and provides guidance for determining the conservation status of populations and …

Outbreaks of crown-of-thorns starfish (Acanthaster spp.) remain a major cause of coral
mortality in the Indo-Pacific, contributing to widespread and accelerating degradation of …

The snap** shrimp (Alpheus heterochaelis) produces a loud snap** sound by an
extremely rapid closure of its snapper claw. One of the effects of the snap** is to stun or …

The rapid development of molecular techniques offers a palette of technical approaches for
population biologists interested in a wide range of questions. For example, these tools can …

This chapter addresses the likelihood of fertilization in the sea, the factors that can mediate
fertilization success, and the ecological and evolutionary consequences of variation in …

Because sperm outnumber eggs, it is often assumed that variation in female reproductive
success has little to do with male or sperm availability. Similarly for males, access to viable …

The fecundity of clonal animals and plants is determined by the number of gravid modules
(polyps, zooids, shoots, ramets) and their reproductive output. We examined the fecundity of …

Many organisms reproduce by releasing gametes into the environment. However, very little
is known about what proportion of released eggs become fertilized. We examined the …
