متن کاملEffects of Wild Pigs on Seedling Survival in California Oak Woodlands
Wild pigs were established around coastal Spanish settlements in California in the 1800s and expanded over the last century by hunting introductions, domestic releases, and natural dispersal. The current distribution of wild pigs is closely associated with oak woodlands where foraging and rooting by the species may impinge on many native species. Rooting disturbance by wild pigs may be especial...
متن کاملSoil water content and emergence time control seedling establishment in three co-occurring Mediterranean oak species
Tree species can differ in their responses to resource availability during the critical phase of establishment, which could influence forest dynamics. In Mediterranean forests, most of the attention has focused on the effects of shade and summer drought on seedling survival, but little is known about the effect of autumn to spring rains on earlier stages of recruitment. A sowing experiment was ...
متن کاملCryptosporidium parvum transport from cattle fecal deposits on California rangelands
