In this way, chimerism may benefit the ants by helping them avoid inbreeding, since ... WebPopulations of many pest insects exhibit ecological and evolutionary dynamics dominated by episodes of population bottlenecks, following population declines (e.g., following implementation of chemical control methods) and occasional local population extinction followed by recolonization. One consequence of these bottlenecks is an increase in the …
WebSelf-pollination is common in plants, and limited seed and pollen dispersal can create localized inbreeding even within outcrossing plants. Consequently, insects regularly encounter inbred plants in nature. Because inbreeding results in elevated homozygosity, greater expression of recessive alleles, and subsequent phenotypic changes in inbred … http://xmpp.3m.com/inbreeding+research+paper

Webthe mean population inbreeding depression (Holsinger 1988, 1991, Uyenoyama et al. 1993, Schultz and Willis 1995). The difference between inbreeding depression estimates based on family means and estimates based on the population mean might be substantial in social insects, where colony and worker characteristics typically data set for constant pressure of 760 torrWebThis type of self-pollination appears to be an adaptation to the windless, drought conditions that are present when flowering occurs, at a time when insects are scarce.
