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.

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 ...

This clearly seems to be a species specific difference. (2) The net fecundity of both species was reduced proportionately by the same amount as the crowding increased. (3) When crowded with males only ...

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 ...

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 ...

Tradeoffs between weaponry and fecundity in snapping shrimp queens vary with eusociality Weakly eusocial queens must trade off their investment in maintaining their fighting claws or producing ...

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.

Without immigrants to replenish its ranks, Europe runs the risk of dying off, Eurostat data show. Every single country in the European Union suffers from a sub-replacement fertility rate, meaning ...
