This study investigated the magnitude of inbreeding depression in fecundity, and whether the depression is purged during six generations of sib mating in the bulb mite, Rhizoglyphus robini. The ...

A moderate reduction in food intake, known as dietary restriction, protects against multiple ageing-related diseases and extends life span, but can also supress growth and fertility. A research group ...

The skew in fecundity was also pronounced for the paternal genotypes (Figure 3). Three of the most commonly inferred genotypes together accounted for 36% of the sporophytes.

I believe that any human fidelity—attending to a place, a spouse, a vocation—brings a similar blessing of fecundity. Such fruit, however, does not come as a reward for jaw-clenched discipline ...

An 18-year study of 27,000 individual trees finds that tree growth and fecundity -- the ability to produce viable seeds -- are more sensitive to climate change than previously thought.
