helminth community structure in an expanding white-winged dove (zenaida asiatica asiatica) population.	helminth communities of 171 fledged white-winged doves (zenaida asiatica asiatica) from the expanding eastern population in texas (usa) were examined from hosts collected 11 june to 19 september 1997 within their historical range, new breeding periphery, and an intermediate area. eleven helminth species, representing 435 individuals, were found. helminths occurred in three microhabitats, of which the small intestine was the most commonly occupied. nematodes dominated numerically (76% of total wo ...	2002	11838230
characteristics of the haemoproteid community in an expanding white-winged dove population.	the haemoproteid community of 171 eastern white-winged doves (zenaida asiatica asiatica) from the expanding texas population was examined using thin blood smears. during summer 1997, heart blood was taken from doves within their historical breeding range (lower rio grande valley of texas), an intermediate region (san antonio and surrounding area), and the new breeding periphery (north central to southeast texas). two species were found: haemoproteus columbae and haemoproteus sacharovi. infracomm ...	2002	12053983
host feeding pattern of culex quinquefasciatus (diptera: culicidae) and its role in transmission of west nile virus in harris county, texas.	the vertebrate hosts of 672 blood-engorged culex quinquefasciatus say, collected in harris county, texas, during 2005, were identified by nucleotide sequencing pcr products of the cytochrome b gene. analysis revealed that 39.1% had acquired blood from birds, 52.5% from mammals, and 8.3% were mixed avian and mammalian blood meals. most frequent vertebrate hosts were dog (41.0%), mourning dove (18.3%), domestic cat (8.8%), white-winged dove (4.3%), house sparrow (3.2%), house finch (3.0%), gray ca ...	2007	17620633
environmental contaminants in white-winged doves (zenaida asiatica asiatica) from the lower rio grande valley of texas, usa.	our study determined if white-winged doves (wwds; zenaida asiatica asiatica) breeding in locations where environmentally persistent contaminants occur in the lower rio grande valley of texas have levels of contaminants that can hinder reproduction. during summer 2003, 70 (32 males, 38 females) adult wwds were collected from 8 at-risk sites. liver tissues were analyzed for ten major and trace elements and muscle tissues were analyzed for 20 organochlorine compounds, 21 polychlorinated biphenyl co ...	2009	19112559
lead concentrations of white-winged doves, zenaida asiatica l., collected in the lower rio grande valley of texas, usa.	white-winged dove (zenaida asiatica l.) exposure to environmentally accessible lead is a management concern. detectable concentrations of lead were found in 142 (66%) of 214 white-winged doves collected in 2002 and 2003 at two wildlife management units in south texas. mean +/- sd lead concentration was 0.70 +/- 1.10 microg/g dry weight and ranged from nd to 11.01 microg/g dw. lead concentrations were significantly lower in the 2002 samples, but similar between management units, age, and gender. ...	2010	20686750
helminth community composition, structure, and pattern in six dove species (columbiformes: columbidae) of south texas.	abstract abstract: the helminth community composition and structure of 6 species of columbids residing in south texas are reported and compared herein. sixty rock pigeons, columba livia (rp), mourning doves, zenaida macroura (md), eurasian collared-doves, streptopelia decaocto (ecd), white-winged doves, zenaida asiatica (wwd), common ground doves, columbina passerina (cgd), and 48 inca doves, columbina inca (id), were collected during the summer of 2006 and examined for helminths. twelve he ...	2011	21955248
vector-host interactions of culex pipiens complex in northeastern and southwestern usa.	studies on the vector-host interactions of culex pipiens complex mosquitoes by sequencing portions of mitochondrial cytochrome b gene indicate that cx. p. pipiens f. pipiens predominantly feed on avian hosts (93.1%), and focus feeding activity on several key bird species, in particular the american robin, the gray catbird, and the house sparrow in connecticut. however, cx. p. quinquefasciatus indiscriminately feed on both birds and mammals. culex p. quinquefasciatus in harris county - texas and ...	2012	23401953
histopathologic and molecular characterization of sarcocystis calchasi encephalitis in white-winged doves ( zenaida asiatica ) and eurasian collared doves ( streptopelia decaocto ), east-central texas, usa, 2010-13.	sarcocystis calchasi is a recently described apicomplexan parasite that causes encephalitis in avian hosts. we diagnosed one white-winged dove ( zenaida asiatica ) and two eurasian collared doves ( streptopelia decaocto ) in texas, us, with a history of neurologic signs with protozoal encephalitis. on histologic examination, all three doves had moderate to severe meningoencephalitis characterized by large numbers of plasma cells, lymphocytes, and macrophages with gliosis and astrocytosis. brain ...	0	27124332
