Conkling, Tara J. (2011-08-08)Predation is the leading cause of nest failure in songbirds. My study identified nest predators of black-capped vireos and white-eyed vireos, quantified the activity of potential predator species, examined the relationships ...
-
Lackey, Melissa A. (2011-08-08)Noise pollution can mask or distort bird songs, which inhibits mating success, predator detection, and parental response to begging calls. Road noise can cause lowered density and reproductive success in songbirds. I ...

Breeding Phenology of Birds: Mechanisms Underlying Seasonal Declines in the Risk of Nest Predation Borgmann, Kathi L.; Conway, Courtney J.; Morrison, Michael L.; Chiaradia, André (PloS One, 2013)

Brown-headed cowbird parasitism on endangered species: relationships with neighboring avian species Farrell, Shannon Leigh (2009-05-15)Brown-headed cowbird (Molothrus ater) parasitism on the endangered black-capped vireo (Vireo atricapilla) is a management concern. Management for black-capped vireos in east-central Texas has focused on habitat restoration ...
-
Klassen, Jessica Anne (2012-07-16)Habitat disturbances play a major role in wildlife distribution. Disturbances such as loss of breeding habitat and fragmentation are of particular concern for Neotropical migrant songbird populations. Additionally, ...

Ecology of the predator assemblage affecting nest success of passerines in Sierra Nevada, California Cocimano, Maria C. (2010-07-14)The endangered willow flycatcher (Empidonax traillii) breeds in mountain meadows in the Sierra Nevada, which have been intensively modified, especially reducing meadow wetness, which favors easy access for mammalian predators ...
-
Lituma, Christopher M. (2010-07-14)The prairies of North America have undergone substantial changes since European settlement in the 1800's, with some estimates suggesting that 96% of the tallgrass prairie has been converted. Multiple factors contributed ...
-
Pope, Theresa (2012-10-19)Many factors affect the productivity of songbirds. Which vegetation types the birds inhabit, nest-site characteristics, and adult behavior at the nest may affect predation and parasitism frequencies, fecundity, and nest ...
-
Campomizzi, Andrew J. (2009-05-15)Invasive species are often implicated in population declines of native species through competition and predation. Red imported fire ant (Solenopsis invicta) predation of songbird nestlings and eggs has been documented. I ...
-
Marshall, Mike E. (2012-07-16)The concept of habitat quality is fundamental to the study of ecology, and ecologists have long recognized the importance of vegetation structure and composition in the assessment of wildlife habitat. Vegetative characteristics ...
-
Groce, Julie Elizabeth (2009-05-15)Several species of small, cavity-nesting owls occur in the Sierra Nevada, including in areas impacted by human activities. The owls typically use standing dead trees (snags) for nest sites. Although descriptive studies ...
-
Stewart, Laura Roe (2012-07-16)Oak wilt is a fatal disease of oaks caused by the fungus Ceratocystis fagacearum. Loss or degradation of habitat due to the disease may negatively affect the federally endangered golden-cheeked warbler (Setophaga chrysoparia). ...
-
Lawson, Ardath L. (2010-10-12)Padre Island National Seashore provides important habitat for wintering grassland birds, which are declining throughout their breeding range, yet oil and gas development is widespread in the park. My objective was to ...
-
Calixto, Alejandro Antonio (2009-05-15)Higher densities of S. invicta in the United States relative to South America are explained mainly by the absence of natural enemies and low interspecific competition (IC). Despite advances in S. invicta management, broadcast ...
-
Long, Ashley Marie (2014-08-08)Most avian habitat selection studies are conducted within small spatial and temporal scales and fail to link habitat selection decisions to reproductive success. This limits our understanding of avian demographic patterns ...
-
Campomizzi, Andrew James (2012-10-19)I investigated the role of extra-pair paternity on use of public information and the interaction between public information and personal information for patch fidelity decisions. It is unknown if songbirds use public ...
-
Butcher, Jerrod Anthony (2009-05-15)Preservation of large tracts of habitat is often recommended for long-term population viability of area-sensitive species. Large tracts may not always be available. Smaller patches, though not able to contain a viable ...
-
Vormwald, Lisa M. (2011-10-21)Understanding factors limiting population growth is critical for species exhibiting declining populations. Reproductive success has an important effect on population dynamics; however, our ability to accurately estimate ...
-
Farrell, Shannon Leigh (2012-07-16)Habitat selection research has focused on the role of vegetative and geologic habitat characteristics or antagonistic behavioral interactions. Conspecifics can confer information about habitat quality and provide positive ...
