| 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 |
| hematologic responses in captive white-winged doves (zenaida asiatica), induced by various radiotransmitter attachments. | white blood cell counts, heterophil-lymphocyte ratios, and leukocyte differentials of captive white-winged doves (zenaida asiatica) from texas equipped with different radiotransmitter attachment packages were monitored. doves were segregated by gender and age by males, females, and hatching year; individuals housed in 30 large outdoor pens in groups of seven. treatments consisted of controls, glue-on transmitters, body loop harnesses, surgically implanted intracoelomic transmitters, surgically i ... | 2005 | 16107674 |
| pollination of saguaro cactus by doves, nectar-feeding bats, and honey bees. | in a large cage, free-flying western white-winged doves, nectar-feeding leptonycteris bats, and honey bees were each effective as cross-pollinators of self-sterile saguaro flowers. seed production and seed viability were not significantly different in fruit from flowers pollinated by these agents. pollination is not a limiting factor in saguaro repopulation. | 1961 | 17781127 |
| cholinesterase activity in white-winged doves exposed to methyl parathion. | captive white-winged doves (zenaida asiatica) were exposed to various levels of methyl parathion (mp) in drinking water to determine effects on brain and blood cholinesterase (che) activity. we conducted two experiments to test the influence of mp dose (the amount of mp actually ingested), mp concentration (the amount of mp per unit water), and exposure duration (number of days exposed to a constant mp concentration) on che activity. plasma che activity was not useful in predicting brain che act ... | 1998 | 9813838 |
| sleep in the dove zenaida asiatica. | electrographic and behavioral observations were made in five adult birds of the genus zenaida asiatica. five different vigilance states were quantitated: (1) active waking (aw) was characterized by constant behavioral activity; the nuchal electromyogram was tonically active with bursts associated to movements. the electroencephalographic pattern was low voltage and high frequency. (2) quiet waking (qw) was characterized by diminished behavioral activity and the eeg pattern was similar to that of ... | 1988 | 3365182 |
| 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 |

| exposure to insecticides of brushland wildlife within the lower rio grande valley, texas, usa. | brushland wildlife within the lower rio grande valley of south texas were studied following applications of eleven insecticides to nearby sugarcane or cotton fields. during the study no wildlife were found dead. mean brain acetylcholinesterase (ache) activity of great-tailed grackles (quiscalus mexicanus) and mourning doves (zenaida macroura) was significantly lower than controls following application of some organophosphorous insecticides. brain ache activity varied significantly among chemical ... | 1987 | 15092751 |
| detection of aflatoxin-contaminated grain by three granivorous bird species. | supplemental feeding of game species and the use of backyard feeders to attract avian wildlife are common practices throughout the united states. however, these activities may expose wildlife to aflatoxins. we tested the hypothesis that wild birds would avoid consuming aflatoxin-contaminated feed. individual northern bobwhites (colinus virginianus), white-winged doves (zenaida asiatica), and green jays (cyanocorax yncas) were presented with feeders that had four compartments, which contained mil ... | 2001 | 11310888 |
| avian thermoregulation in the heat: resting metabolism, evaporative cooling and heat tolerance in sonoran desert doves and quail. | birds in subtropical deserts face significant thermoregulatory challenges because environmental temperatures regularly exceed avian body temperature. to understand the differing susceptibility of desert birds to increasing temperatures, we examined thermoregulatory performance and estimated heat tolerance limits (htls) for three sonoran desert nesting bird species - gambel's quail, mourning doves and white-winged doves. using flow-through respirometry we measured daytime resting metabolism, evap ... | 2015 | 26582934 |
| keeling plots for hummingbirds: a method to estimate carbon isotope ratios of respired co(2) in small vertebrates. | the carbon isotope composition of an animal's breath reveals the composition of the nutrients that it catabolizes for energy. here we describe the use of keeling plots, a method widely applied in ecosystem ecology, to measure the delta(13)c of respired co(2) of small vertebrates. we measured the delta(13)c of rufous hummingbirds ( selasphorus rufus) in the laboratory and of mourning ( zenaida macroura) and white-winged ( z. asiatica) doves in the field. in the laboratory, when hummingbirds were ... | 2004 | 15309607 |
| survival of trichomonas gallinae in white-winged dove carcasses. | survival of trichomonas gallinae was examined in white-winged dove (zenaida asiatica) carcasses to assess whether birds that have been dead up to 8 hr can be sampled reliably for this protozoan. carcasses of 100 t. gallinae-positive white-winged doves were separated into four groups of 25 birds, representing 2, 4, 6, and 8 hr post mortem sampling intervals and placed into an environmental chamber maintained at 27 c and 75% relative humidity. live t. gallinae were isolated in 96, 100, 100, and 92 ... | 2000 | 10941743 |
| partitioning of evaporative water loss in white-winged doves: plasticity in response to short-term thermal acclimation. | we investigated changes in the relative contributions of respiratory evaporative water loss (rewl) and cutaneous evaporative water loss (cewl) to total evaporative water loss (tewl) in response to short-term thermal acclimation in western white-winged doves zenaida asiatica mearnsii. we measured rewl, cewl, oxygen consumption and carbon dioxide production in a partitioned chamber using flow-through respirometry. in doves housed for 2-4 weeks in a room heated to ca. 43 degrees c during the day, t ... | 2004 | 14668305 |
