Reduced fecundity in small populations of the rare plant Gentianopsis ciliate (Gentianaceae) Reduced fecundity in small populations of the rare plant Gentianopsis ciliate (Gentianaceae)
Habitat destruction is the main cause for the biodiversity crisis. Surviving populations are often fragmented, i.e., small and isolated from each other. Reproduction of plants in small populations is often reduced, and this has been attributed to inbreeding depression, reduced attractiveness for pollinators, and reduced habitat quality in small populations. Here we present data on the...

Industrial effluents as a source of mercury contamination in terrestrial riparian vertebrates Industrial effluents as a source of mercury contamination in terrestrial riparian vertebrates
Eight species of piscivorous and insectivorous birds and one species of bat collected along Virginia's North Fork of the Holston River contained elevated mercury residues. The ubiquitous occurrence of mercury in riparian insectivores implicates aquatic insects as a vehicle for spreading mercury contamination from one ecosystem to another and expands the ecological ramifications of...

Atlantic Flyway review: Region V Atlantic Flyway review: Region V
One new station was added to the Region V roster in 1981: Bestgate in the Annapolis suburbs. We also have a summary from Cylburn Arboretum in Baltimore City, a station that had not reported since 1977. The total regional effort of 82,282 net-hours was surpassed only in 1980. Although the total net-hours of operation decreased only 10.8% from 1980, the number of birds banded dropped 15.8%...

Brewer's sparrow (Spizella breweri) Brewer's sparrow (Spizella breweri)
Many of the known recoverable coal reserves in the Western United States occur within the breeding and wintering range of the Brewer's sparrow. Although the species is common throughout much of its breeding range, local and regional populations may be adversely affected due to mining-related disturbances and habitat loss. The species may serve as a valuable indicator of the impacts of...
