| prevalence of mycoplasma antibodies in lesser prairie-chicken sera. | serologic testing by the serum plate agglutination (spa) procedure was performed to detect the presence of cross-reacting antibodies to mycoplasma meleagridis, mycoplasma synoviae, and mycoplasma gallisepticum in lesser prairie-chickens (tympanuchus pallidicinctus) trapped over a 2-yr period in finney and kearny counties of southwestern kansas. sera examined from birds (n = 50) obtained in march-april 2000 tested positive for m meleagridis, m. synoviae, and m. gallisepticum at levels of 6%, 10%, ... | 2002 | 12243537 |
| infectious disease survey of lesser prairie chickens in north texas. | lesser prairie chicken (tympanuchus pallidicinctus) abundance, like that of most grassland birds, has declined rangewide for decades. although habitat loss and degradation are likely ultimate causes for this decline, infectious agents, particularly microparasites, could be proximate contributors. no surveys of pathogenic bacteria or viruses have been published for this species. we surveyed 24 free-living lesser prairie chickens from hemphill county, texas (usa), for evidence of exposure to salmo ... | 2002 | 12528454 |
| genetic variation within and among fragmented populations of lesser prairie-chickens (tympanuchus pallidicinctus). | as a result of recurrent droughts and anthropogenic factors, the range of the lesser prairie-chicken (tympanuchus pallidicinctus) has contracted by 92% and the population has been reduced by approximately 97% in the past century, resulting in the smallest population size and most restricted geographical distribution of any north american grouse. we examined genetic variation through dna sequence analysis of 478 base pairs of the mitochondrial genome and by assaying allelic variation at five micr ... | 2003 | 12675823 |
| survey for coccidia and haemosporidia in the lesser prairie-chicken (tympanuchus pallidicinctus) from new mexico with description of a new eimeria species. | blood films and fecal samples of the lesser prairie-chicken (tympanuchus pallidicinctus) were examined for parasites when we surveyed specimens captured during a radio-tracking study conducted in chaves county, new mexico (usa). all birds were captured on the caprock wildlife habitat management area, administered by the bureau of land management. samples were collected in late march, april, and early may 1998-2000. oocysts were detected in five of 64 (8%) birds sampled and, upon sporulation, wer ... | 2003 | 12910762 |
| genetic structure among closely spaced leks in a peripheral population of lesser prairie-chickens. | we evaluated the genetic structure of birds from four closely spaced leks in a peripheral population of lesser prairie-chickens (tympanuchus pallidicinctus). analyses of molecular variance revealed significant genetic structuring among birds from different leks for six microsatellite loci (fst = 0.036; p = 0.002), but we found no genetic differentiation at the mtdna control region. significant deviations from hardy-weinberg revealed an excess of homozygote genotypes within each of the leks studi ... | 2004 | 14717904 |
| gis habitat analysis for lesser prairie-chickens in southeastern new mexico. | we conducted geographic information system (gis) habitat analyses for lesser prairie-chicken (lpch, tympanuchus pallidicinctus) conservation planning. the 876,799 ha study area included most of the occupied habitat for the lpch in new mexico. the objectives were to identify and quantify: 1. suitable lpch habitat in new mexico, 2. conversion of native habitats, 3. potential for habitat restoration, and 4. unsuitable habitat available for oil and gas activities. | 2006 | 17144922 |
| recent range expansion and divergence among north american prairie grouse. | prairie grouse (genus: tympanuchus) once existed throughout much of north america but have recently experienced significant population declines, isolation, and extinction. in previous molecular studies, contrasting patterns or an unresolved polytomy among tympanuchus taxa (tympanuchus phasianellus, tympanuchus pallidicinctus, and tympanuchus cupido) have resulted from traditional phylogenetic methods. as an alternative approach, the timing of expansion and the demographic processes that may have ... | 2008 | 18283050 |
| avoidance behavior by prairie grouse: implications for development of wind energy. | new wind-energy facilities and their associated power transmission lines and roads are being constructed at a rapid pace in the great plains of north america. nevertheless, little is known about the possible negative effects these anthropogenic features might have on prairie birds, one of the most threatened groups in north america. we examined radiotelemetry tracking locations of lesser prairie-chickens (tympanuchus pallidicinctus) and greater prairie-chickens (t. cupido) in two locations in ok ... | 2009 | 19500121 |
| habitat selection and the perceptual trap. | the concept of "ecological traps" was introduced over three decades ago. an ecological trap occurs when, by various mechanisms, low-quality (yielding low fitness) habitat is more attractive than good habitat, thus coaxing individuals to settle there despite a resultant loss of fitness. empirical work on such traps has increased dramatically in the past decade, but the converse-avoidance of high-quality habitat because it is less attractive, what we term a "perceptual trap" has remained largely u ... | 2010 | 21265448 |
| balancing energy development and conservation: a method utilizing species distribution models. | alternative energy development is increasing, potentially leading to negative impacts on wildlife populations already stressed by other factors. resource managers require a scientifically based methodology to balance energy development and species conservation, so we investigated modeling habitat suitability using maximum entropy to develop maps that could be used with other information to help site energy developments. we selected one species of concern, the lesser prairie-chicken (lpch; tympan ... | 2011 | 21400221 |
| the parasitic eyeworm oxyspirura petrowi as a possible cause of decline in the threatened lesser prairie-chicken (tympanuchus pallidicinctus). | lesser prairie-chickens (tympanuchus pallidicinctus) have been declining range wide since the early 1900's despite efforts to establish conservation and improve their habitat. in early 2014, the lesser prairie-chicken was listed as a threatened species under the u.s endangered species act and the need to find out why they are declining is more important than ever. nine hunter shot lesser prairie-chickens were donated and sampled for the presence or absence of the eyeworm oxyspirura petrowi, a kn ... | 2014 | 25250776 |
| the effect of listing the lesser prairie chicken as a threatened species on rural property values. | this paper estimates the effect of endangered species act protections for the lesser prairie chicken (tympanuchus pallidicinctus) on rural property values in oklahoma. the political and legal controversy surrounding the listing of imperiled species raises questions about the development restrictions and opportunity costs the endangered species act imposes on private landowners. examining parcel-level sales data before and after the listing of the endemic lesser prairie chicken, we employ differe ... | 2017 | 28092751 |
| relative importance of climate variables to population vital rates: a quantitative synthesis for the lesser prairie-chicken. | climate change is expected to affect temperature and precipitation means and extremes, which can affect population vital rates. with the added complexity of accounting for both means and extremes, it is important to understand whether one aspect is sufficient to predict a particular vital rate or if both are necessary. to compare the predictive ability of climate means and extremes with geographic, individual, and habitat variables, we performed a quantitative synthesis on the vital rates of les ... | 2017 | 27684075 |
| the predicted influence of climate change on lesser prairie-chicken reproductive parameters. | the southern high plains is anticipated to experience significant changes in temperature and precipitation due to climate change. these changes may influence the lesser prairie-chicken (tympanuchus pallidicinctus) in positive or negative ways. we assessed the potential changes in clutch size, incubation start date, and nest survival for lesser prairie-chickens for the years 2050 and 2080 based on modeled predictions of climate change and reproductive data for lesser prairie-chickens from 2001-20 ... | 2013 | 23874549 |
| divergent color signals from homologous unfeathered ornaments in two congeneric grouse. | color-based visual signals are important aspects of communication throughout the animal kingdom. individuals evaluate color to obtain information about age and condition and to behave accordingly. birds display a variety of striking, conspicuous colors and make ideal subjects for the study of color signaling. while most studies of avian color focus on plumage, bare unfeathered body parts also display a wide range of color signals. mate choice and intrasexual competitive interactions are easily o ... | 2019 | 31695891 |
| using an individual-based model to assess common biases in lek-based count data to estimate population trajectories of lesser prairie-chickens. | researchers and managers are often interested in monitoring the underlying state of a population (e.g., abundance), yet error in the observation process might mask underlying changes due to imperfect detection and availability for sampling. additional heterogeneity can be introduced into a monitoring program when male-based surveys are used as an index for the total population. often, male-based surveys are used for avian species, as males are conspicuous and more easily monitored than females. ... | 2019 | 31100093 |
| interactive effects of severe drought and grazing on the life history cycle of a bioindicator species. | we used the lesser prairie-chicken (tympanuchus pallidicinctus), an iconic grouse species that exhibits a boom-bust life history strategy, on the southern high plains, usa, as a bioindicator of main and interactive effects of severe drought and grazing. this region experienced the worst drought on record in 2011. we surveyed lesser prairie-chicken leks (i.e., communal breeding grounds) across 12 years that represented 7 years before the 2011 drought (predrought) and 4 years during and following ... | 2018 | 30377522 |
| guidelines for managing lesser prairie-chicken populations and their habitats. | lesser prairie-chicken (tympanuchus pallidicinctus) populations have declined by >90% since the 1800s. these declines have concerned both biologists and private conservation groups and led to a petition to list the lesser prairie-chicken as threatened under the endangered species act. most of the land in the current range of the lesser prairie-chicken is privately owned, and declines have been primarily attributed to anthropogenic factors. conversion of native rangeland to cropland and excessive ... | 2004 | 32327860 |
