Boll weevil eradication: a model for sea lamprey control? Boll weevil eradication: a model for sea lamprey control?
Invasions of boll weevil (Anthonomus grandis) into the United States and sea lamprey (Petromyzon marinus) into the Great Lakes were similar in many ways. Important species (American cotton, Gossypium hirsutum, and lake trout, Salvelinus namaycush) and the industries they supported were negatively affected. Initial control efforts were unsuccessful until pesticides and application...

Impacts of cowbird parasitism on wood thrushes and other neotropical migrants in suburban Maryland forests Impacts of cowbird parasitism on wood thrushes and other neotropical migrants in suburban Maryland forests
During 1988-1993, we monitored nests of neotropical migrant birds in seven suburban Maryland forests to compare parasitism and predation rates in forests of different areas. Of 1,122 nests monitored, 672 were of Wood Thrush, the most commonly found nesting species. Study sites were forests that ranged in size from 21 ha to more than 1,300 ha in the Piedmont and Coastal Plain regions of...

Cowbird parasitism in grassland and cropland in the northern Great Plains Cowbird parasitism in grassland and cropland in the northern Great Plains
The landscape of the Great Plains has been greatly altered by human activities in the past century, and several grassland passerines have experienced significant population declines in recent decades. We explore here whether brood parasitism by Brown-headed Cowbirds, which are abundant in the Great Plains, has contributed to these declines. We measured the frequency of cowbird parasitism...
