Breeding Habits of Water Birds - Chapter 1. INTRODUCTION Many species aggregate for feeding, roosting and nesting activities, which are prevalent among water birds (Weins, 1992). Why animals form breeding colonies is a major unresolved question in evolutionary biology. The topic continues to stir lively debate (Danchin & Wagner 1997, Tella et al., 1998) and has been the focus of long term studies (Hoogland 1995; Brown & Brown 1996; Danchin et al. 1998). One of the principal issues has been whether colonies form due to limited breeding habitat; with animals forced into nesting aggregations at a nest cost, or result from social benefits of clustering (Food finding, reduced predation; Lack 1968; Alexander 1974; Hoogland & Sherman 1976; Wittenberger 1981)....   [tags: Biology ] 976 words

Does Religion belong in Public Schools? - When looking at the history of America, it is fascinating to see how the public schooling system even got started. The first schools in America were not public schools, as many would presume. Instead, “the first schools in the United States were religious and not secular” (Elifson 1). Nearly all public schools, up to the 1960’s incorporated religion and prayer in their classrooms; however, in the last 50 years, prayer and religion in public schools has been debated over countless times. Even in Hudsonville, Michigan, which holds the record in the Guinness Book of World Records for having the most churches on a single street, there is much debate over prayer and the teaching of Christianity, or any religion, in the public schools....   [tags: Religion]
