| patterns of avian nest predators and a brood parasite among restored riparian habitats in agricultural watersheds. | in fragmented edge-dominated landscapes, nest predation and brood parasitism may reduce avian reproductive success and, ultimately, populations of some passerine species. in the fragmented agroecosystem of northwest mississippi, placement of drop-pipe structures has been used as a restoration technique for abating gully erosion along stream banks. these actions have formed small herbaceous and woody habitat extensions into former agricultural lands. we quantified species relative abundances, spe ... | 2005 | 16160783 |
| population genetics of the hispid cotton rat (sigmodon hispidus): patterns of genetic diversity at the major histocompatibility complex. | the hispid cotton rat, sigmodon hispidus, is a common rodent widely distributed across the southern usa and south into south america. to characterize major histocompatibility complex (mhc) diversity in this species and to elucidate large-scale patterns of genetic partitioning, we examined mhc genetic variability within and among 13 localities, including a disjunct population in arizona and a population from costa rica that may represent an undescribed species. we also tested the hypothesis that ... | 2001 | 11555238 |
