Evaluating causes of population change in North American insectivorous songbirds Evaluating causes of population change in North American insectivorous songbirds

Although the North American Breeding Bird Survey (BBS) is a principal source of information regarding populations of most North American bird species, many features of the survey complicate analysis of population change. Correlation studies based on BBS data cannot be used to unambiguously define cause and effect relationships. Recently, B?hning-Gaese et al. (1993) presented an analysis...

Occurrence of Trypanosoma cruzi in Maryland Occurrence of Trypanosoma cruzi in Maryland

During 1954-1960, 2005 mammals of 18 species collected at the Patuxent Wildlife Research Center, Maryland, were examined for trypanosomes. T. cruzi was found in 10 raccoons between October 31 and November 30. Infection occurred in 2 percent of all raccoons sampled, and in 11.3 percent of the 80 raccoons sampled in November. Examination was by direct smears, stained smears and cultures of...

The role of birds in the epizootiology of eastern encephalitis The role of birds in the epizootiology of eastern encephalitis

Eastern encephalitis is a disease of horses, man, birds, and reptiles caused by a virus that in some hosts results in an inflammation of the brain. The causative virus belongs to a group classified as mosquito-borne encephalitides. This disease, more commonly called eastern equine encephalitis in the past, occurs from Wisconsin and Texas to the Atlantic coast and is particularly...

Determination of 2-isovaleryl-1,3-indandione with 2,4-dinitrophenylhydrazine. Rodenticide Analysis. Determination of 2-isovaleryl-1,3-indandione with 2,4-dinitrophenylhydrazine. Rodenticide Analysis.

At present, three 2-alkyl-1,3-indandiones (PMP, pival, and diphacinon) are widely used as rodenticides. Because analytical procedures now in use are empirical and do not furnish adequate or positive means for distinguishing among these closely related compounds, studies were undertaken to develop a sensitive and specific method for the determination of PMP. The relation between KCN and...
