Book Population Differentiation Among Snowy Plovers Charadrius Alexandrinus in North America

Download or read book Population Differentiation Among Snowy Plovers Charadrius Alexandrinus in North America written by Leah R. Gorman and published by . This book was released on 2000 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two North American subspecies of Snowy Plovers (Charadrius alexandrinus) have been described: the Cuban Snowy Plover (C. a. tenuirostris) and the Western Snowy Plover (C. a. nivosus). Coastal populations of the Western Snowy Plover are listed as Threatened under the U.S. Endangered Species Act, while populations of the Cuban Snowy Plover in the southeastern U.S. and Puerto Rico show evidence of decline and are being considered for listing. To clarify the relationships among populations, we examined variation in mitochondrial (mtDNA) sequences and at inter-simple sequence repeat (ISSR) loci among 8 populations distributed across North America and the Caribbean. MtDNA d-loop region sequences (322 bp, n = 126) revealed 8 haplotypes, with one haplotype unique to Puerto Rico, and indicated that Puerto Rico is significantly differentiated from all mainland populations. Conversely, neighbor-joining analysis of 16 ISSR loci suggests that Puerto Rico is nested within a cluster of populations from eastern continental North America. Evidence for structure among continental populations was weak among mtDNA haplotypes (ST = 0.025, p = 0.178), but analysis of ISSR markers supported subdivision into groups east and west of the Rocky Mountains (IST = 0.445, p

Download or read book Snowy Plover Nesting Ecology on the Oregon Coast written by Ruth A. Wilson and published by . This book was released on 1980 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possibility of reduced abundance of western snowy plovers (Charadrius alexandrinus nivosus) in the face of an altered habitat prompted a study of snowy plover breeding activities and nesting habitat on the Oregon coast during 1978 and 1979. At 4 study areas with varying levels of recreational use, nests were located and observed. Cover characteristics of nesting habitat were assessed with line intercept and mThe possibility of reduced abundance of western snowy plovers (Charadrius alexandrinus nivosus) in the face of an altered habitat prompted a study of snowy plover breeding activities ana nesting habitat on the Oregon coast during 1978 and 1979. At 4 study areas with varying levels of recreational use, nests were located and observed. Cover characteristics of nesting habitat were assessed with line intercept and m2 plot sampling. During May and June of each year, appropriate habitat on the coast was surveyed for snowy plovers. Snowy plovers were persistent and adaptable in nesting activities but had low reproductive success (0.2 to 0.4 chicks fledged per female). Of 72 nests observed, at least 19 were lost to corvid predation and 11 were destroyed by storms and moving sand; 9 nests were successful. Factors responsible for loss of chicks prior to fledging were not determined. Relationships were not apparent between nest success and level of recreational activity among study areas. Extensive areas of flat, open sand with sparse cover (an average of 13%) characterized nesting habitat within a 20 m radius of nests. In the immediate vicinity of nests there was an average of 26% cover. Surveys of appropriate habitat on the coast disclosed a maximum of 100 adults and fledged juveniles; 12 discrete beach segments were used by snowy plovers in the 2 years plot sampling.
