| birds of a high-altitude cloud forest in alta verapaz, guatemala. | the northern central american highlands have been recognized as endemic bird area, but little is known about bird communities in guatemalan cloud forests. from 1997 to 2001 a total of 142 bird species were recorded between 2000 and 2400 masl in cloud forest and agricultural clearings on montaña caquipec (alta verapaz, guatemala). the bird community is described based on line transect counts within the forest. pooling census data from undisturbed and disturbed forest, the gray-breasted wood-wren ... | 2005 | 17354466 |
| responses of a federally endangered songbird to understory thinning in oak-juniper woodlands. | wildlife conservation and management on military lands must be accomplished in the context of military readiness, which often includes ground-based training that is perceived to conflict with wildlife needs and environmental regulations. from 2008‒2012, we examined territory density, pairing success, and fledging success of the federally endangered golden-cheeked warbler (setophaga chrysoparia; hereafter warbler) in relation to removal of small-diameter trees from the understory of mature oak-ju ... | 2017 | 28078389 |
| a before-after control-impact assessment to understand the potential impacts of highway construction noise and activity on an endangered songbird. | anthropogenic noise associated with highway construction and operation can have individual- and population-level consequences for wildlife (e.g., reduced densities, decreased reproductive success, behavioral changes). we used a before-after control-impact study design to examine the potential impacts of highway construction and traffic noise on endangered golden-cheeked warblers (setophaga chrysoparia; hereafter warbler) in urban texas. we mapped and monitored warbler territories before (2009-20 ... | 2017 | 28070300 |
| conspecific cues and breeding habitat selection in an endangered woodland warbler. | 1. research on habitat selection has focused on the role of vegetative and geologic characteristics or antagonistic behavioural interactions. 2. conspecifics can confer information about habitat quality and provide positive density-dependent effects, suggesting habitat selection in response to the presence of conspecifics can be an adaptive strategy. 3. we conducted a manipulative field experiment investigating use of conspecific location cues for habitat selection and consequent reproductive ou ... | 2012 | 22548648 |
| predicting patch occupancy in fragmented landscapes at the rangewide scale for an endangered species: an example of an american warbler. | aim: our objective was to identify the distribution of the endangered golden-cheeked warbler (setophaga chrysoparia) in fragmented oak-juniper woodlands by applying a geoadditive semiparametric occupancy model to better assist decision-makers in identifying suitable habitat across the species breeding range on which conservation or mitigation activities can be focused and thus prioritize management and conservation planning. location: texas, usa. methods: we used repeated double-observer detecti ... | 2012 | 22408381 |
| quantifying the importance of patch-specific changes in habitat to metapopulation viability of an endangered songbird. | a growing number of programs seek to facilitate species conservation using incentive-based mechanisms. recently, a market-based incentive program for the federally endangered golden-cheeked warbler (dendroica chrysoparia) was implemented on a trial basis at fort hood, an army training post in texas, usa. under this program, recovery credits accumulated by fort hood through contracts with private landowners are used to offset unintentional loss of breeding habitat of golden-cheeked warblers withi ... | 2011 | 22073637 |
| habitat fragmentation and genetic diversity of an endangered, migratory songbird, the golden-cheeked warbler (dendroica chrysoparia). | landscape genetic approaches offer the promise of increasing our understanding of the influence of habitat features on genetic structure. we assessed the genetic diversity of the endangered golden-cheeked warbler (dendroica chrysoparia) across their breeding range in central texas and evaluated the role of habitat loss and fragmentation in shaping the population structure of the species. we determined genotypes across nine microsatellite loci of 109 individuals from seven sites representing the ... | 2008 | 18397218 |
