Watershield use by ring-necked ducks Watershield use by ring-necked ducks
During 1993-94 and 1994-95, the amount of watershield (Brasenia schreberi) in selected Maryland wetlands was determined to see if a relationship existed between the amount of watershield on a wetland and the number of ring-necked ducks (Aythya collaris) observed on that wetland. Data were collected for two years from eight different wetlands on the Patuxent Research Refuge in Laurel...

Migration chronology and distribution of redheads on the lower Laguna Madre, Texas Migration chronology and distribution of redheads on the lower Laguna Madre, Texas
An estimated 80% of redheads (Aythya americana) winter on the Laguna Madre of southern Texas and Mexico. Because there have been profound changes in the Laguna Madre over the past three decades and the area is facing increasing industrial and recreational development, we studied the winter distribution and habitat requirements of redheads during two winters (1987-1988 and 1988-1989) on...

Forty-first supplement to the American Ornithologists' Union Check-list of North American birds Forty-first supplement to the American Ornithologists' Union Check-list of North American birds
This seventh supplement after the publication of the 6th edition (1983) of the AOU Check-list of North American Birds includes taxonomic and nomenclatural changes adopted by the Committee on Classification and Nomenclature between 15 March 1995 and 15 March 1997. Because this will be the last supplement before the publication of the 7th edition of the Check-list, it also summarizes other...

He developed a broad interest in natural history at an early age, being stimulated by his mother, a kindergarten teacher, who introduced him to nature books. His interest was strengthened by Harold L. Madison, Director of the Park Museum in Providence, an Associate ( =...

Field studies on pesticides and birds: unexpected and unique relations Field studies on pesticides and birds: unexpected and unique relations
We review the advantages and disadvantages of experimental and field studies for determining effects of pesticides on birds. Important problems or principles initially discovered in the field include effects of DDT (through its metabolite DDE) on eggshell thickness, reproductive success, and population stability; trophic-level bioaccumulation of the lipid-soluble organochlorine...

Mercury residues in south Florida apple snails (Pomacea paludosa) Mercury residues in south Florida apple snails (Pomacea paludosa)
Mercury concentrations in the sediments of south Florida wetlands have increased three fold in the last century (Rood et al. 1993). Because south Florida is home to many endemic and endangered species, it is important to understand the potential impacts of mercury in this ecosystem's food web. Recent research by Malley et al. (1996) has shown mollusks to be sensitive indicators of methyl...
