Factors Affecting Litter Size in Pigs
Litter size in pigs has been defined in a number of ways, depending on the goals of the specific experiment. Number of total piglets, including mummies and stillborns, number of fully formed piglets, excluding mummies but including stillborns, and the number of piglets born alive have all been used as endpoints of litter size research. The end measures are chosen with the idea that the causes o...
متن کاملModelling factors affecting litter mass components of pine stands
Litter mass represents a key factor in the process of carbon sequestration. Pine plantations are known to accumulate high amounts of litter, which may act as real carbon sink only if it persists for long time. Thus, predicting litter mass by means of robust and straightforward models which convey information from several ecological predictors become crucial in this framework. The aim of this pa...
متن کاملEpistasis affecting litter size in mice.
Litter size is an important reproductive trait as it makes a major contribution to fitness. Generally, traits closely related to fitness show low heritability perhaps because of the corrosive effects of directional natural selection on the additive genetic variance. Nonetheless, low heritability does not imply, necessarily, a complete absence of genetic variation because genetic interactions (e...

متن کاملControls over leaf litter decomposition in wet tropical forests.
Tropical forests play a substantial role in the global carbon (C) cycle and are projected to experience significant changes in climate, highlighting the importance of understanding the factors that control organic matter decomposition in this biome. In the tropics, high temperature and rainfall lead to some of the highest rates of litter decomposition on earth, and given the near-optimal abioti...
