Reassignment Of Some Caryospora Species (Apicomplexa: Eimeriidae) To Eumonospora (Apicomplexa: Sarcocystidae) And A Summary, Donald W. Duszynski
Reassignment Of Some Caryospora Species (Apicomplexa: Eimeriidae) To Eumonospora (Apicomplexa: Sarcocystidae) And A Summary, Donald W. Duszynski
MANTER: Journal of Parasite Biodiversity
This review was crafted to clear up some of the current confusion regarding the correct taxonomic placement of those apicomplexan coccidians that produce unique monosporocystic octosporozoic (1 sporocyst with 8 sporozoites) oocysts during the sexual phase of their life history in vertebrate hosts. Currently, such oocysts have been placed in 1 of 4 genera, Avispora, Caryospora, Karyospora, or Eumonospora, 2 of which are no longer accepted or useful (Avispora and Karyospora). My review suggests that to present (2023) there are 62 valid Caryospora and 26 valid Eumonospora species. Caryospora species are recorded from a bird …

The classification of bird species is of significant importance in the field of ornithology, as it plays an important role in assessing and monitoring environmental dynamics, including habitat modifications, migratory behaviors, levels of pollution, and disease occurrences. Traditional methods of bird classification, such as visual identification, were time-intensive and required a high level of expertise. However, audio-based bird species classification is a promising approach that can be used to automate bird species identification. This study aims to establish an audio-based bird species classification system for 264 Eastern African bird species employing modified deep transfer learning. In particular, the pre-trained EfficientNet …

Investigating Birds As Dispersal Vectors Of Litylenchus Crenatae Subsp. Mccannii (Anguinidae), The Nematode Associated With Beech Leaf Disease, Spencer Rock Parkinson
Graduate Theses, Dissertations, and Problem Reports (ETD)
Beech leaf disease (BLD) is an emerging forest pathogen primarily affecting American beech (Fagus grandifolia, Ehrh.) in North America and has been attributed to tree mortality of sapling sized trees within five to seven years of infection. Symptoms typically occur in regenerating American beech thickets sprouting from roots of trees killed by beech bark disease. Scientists first observed BLD in Ohio in 2012 and currently has spread to 15 states in the USA and one Canadian province. The nematode Litylenchus crenatae subsp. mccannii (Lcm) is highly associated with BLD symptoms, interveinal chlorosis and defoliation of leaves, and is currently …

H7n9 Influenza A Virus Transmission In A Multispecies Barnyard Model, Angela M. Bosco-Lauth, Anna Rodriguez, Rachel M. Maison, Stephanie M. Porter, J. Jeffrey Root
United States Department of Agriculture Wildlife Services: Staff Publications
Influenza A viruses are a diverse group of pathogens that have been responsible for millions of human and avian deaths throughout history. Here, we illustrate the transmission potential of H7N9 influenza A virus between Coturnix quail (Coturnix sp.), domestic ducks (Anas platyrhynchos domesticus), chickens (Gallus gallus domesticus), and house sparrows (Passer domesticus) co-housed in an artificial barnyard setting. In each of four replicates, individuals from a single species were infected with the virus. Quail shed virus orally and were a source of infection for both chickens and ducks. Infected chickens transmitted the virus to quail but not to ducks or …

Effects Of Climate Change And Landscape-Scale Forest Management On Avian Communities, Abundance, And Nest Success In The Appalachian Mountains, Hannah L. Clipp
Graduate Theses, Dissertations, and Problem Reports (ETD)
Birds are integral components of ecosystems and account for billions of dollars in tangible benefits to humans. As such, recent continental declines of bird species have ecological and economic consequences, providing the impetus for my dissertation research. I identified knowledge gaps and proposed novel questions about how birds in the Appalachian Mountains are influenced by changing environmental conditions due to climate change and forest management. The Appalachian Mountains encompass an important biogeographical region with high conservation value due to its myriad habitats and corresponding bird species diversity. Thus, there is a critical need to evaluate the effects of shifting climate …

Using Audio Recording Devices And Multiseason Occupancy Modelling To Evaluate Clark's Nutcracker (Nucifraga Columbiana) Occurrence In Whitebark Pine Habitats Of Washington's Cascade Mountains, Lauren Taracka
Undergraduate Honors Theses
The Clark’s nutcracker (Nucifraga columbiana) and whitebark pine (Pinus albicaulis), both native to the harsh subalpine habitats of Washington’s Cascade Mountains, are being negatively impacted by white pine blister rust (Cronartium ribicola), the mountain pine beetle (Dendroctonus ponderosae), and climate change. As temperatures continue to warm, while many species at lower elevations can move upward in elevation to suit their temperature needs, subalpine species do not have that option. Whitebark pine is a keystone tree species - numerous animals consume its high fat, high energy seeds; it’s a nurse tree, providing shelter …

Birds And Vegetation Structure Of Isolated Juniper And Oak Communities In The Trans-Pecos Chihuahuan Desert., Kayla Garza
Open Access Theses & Dissertations
Birds of the Trans-Pecos region are historically understudied, with most literature covering birds of desert grasslands and scrub in New Mexico and Northern Mexico. A multitude of vegetation communities within the Chihuahuan Desert have also been neglected due to this gap in the research, for reasons including lack of access to public or preserve land in West Texas, and rough terrain. Indio Mountains Research Station (IMRS), is located 42-km southwest of Van Horn, Texas and encompasses many different vegetation communities, including juniper-oak habitats of arroyo and canyon systems. The purpose of this study was to document the bird species utilizing …
To Live And Fly In La: Using Bird Strike And Management Program Information To Improve Safety At Airports In The Los Angeles Basin, Todd J. Pitlik, Elizabeth Hermann, Eric Peralta, Brian E. Washburn
To Live And Fly In La: Using Bird Strike And Management Program Information To Improve Safety At Airports In The Los Angeles Basin, Todd J. Pitlik, Elizabeth Hermann, Eric Peralta, Brian E. Washburn
United States Department of Agriculture Wildlife Services: Staff Publications
Wildlife-aircraft collisions (wildlife strikes) pose a serious safety risk to aircraft. Wildlife strikes can be evaluated at different levels, include efforts to examine these problems at the national, regional, or state level, or for an individual airport. Similarly, wildlife strikes involving individual wildlife species or guilds can be examined at varying scales. Although wildlife strike analyses at the national, regional, or species/guild level are valuable, airport-specific analyses are essential for the effective implementation and evaluation of integrated wildlife damage management programs as these actions are conducted at the airport level. The species that present hazards to safe aircraft operations varies …

The Long Shadow Of Senescence: Age Impacts Survival And Territory Defense In Loons, Walter H. Piper, Kristin M. Brunk, Joel A. Flory, Michael W. Meyer
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Senescence, increased mortality that occurs among animals of advanced age, impacts behavior and ecology in many avian species. We investigated actuarial, reproductive, and behavioral senescence using capture, marking, and resighting data from a 26-year study of common loons (Gavia immer). Territorial residents of both sexes exhibited high annual survival (0.94) until their mid 20s, at which point survival fell to 0.76 and 0.77 in males and females, respectively. Sexual symmetry in actuarial senescence is somewhat surprising in this species, because males make a substantially greater investment in territory defense and chick-rearing and because males engage in lethal contests for territory …

Factors Affecting Trace Element Accumulation In Livers Of Avian Species From East Poland, Ignacy Kitowski, Dariusz Wiacek, Agnieszka Sujak, Andrzej Komosa, Michal Swietlicki
Turkish Journal of Zoology
The aim of this study was to determine the concentration of 12 elements in the livers of 14 different species of birds from East Poland, as well as factors affecting their accumulation. The greatest amount of Cd was found in the livers of woodcocks. Analyses showed that Cd accumulation in the liver was associated with the consumption of soil invertebrates. Our data show that some corvids were the most vulnerable to the effects of lead bullets. In the livers of some of them, lead levels exceeded 6 mg/kg. Expansion of food niches in the direction of omnivorous species limited the …

Biology Faculty Articles
Background: The wide range of complex photic systems observed in birds exemplifies one of their key evolutionary adaptions, a well-developed visual system. However, genomic approaches have yet to be used to disentangle the evolutionary mechanisms that govern evolution of avian visual systems.
Results: We performed comparative genomic analyses across 48 avian genomes that span extant bird phylogenetic diversity to assess evolutionary changes in the 17 representatives of the opsin gene family and five plumage coloration genes. Our analyses suggest modern birds have maintained a repertoire of up to 15 opsins. Synteny analyses indicate that PARA and PARIE pineal …

A study was conducted on mercury renal concentration in 154 individuals of 28 species of birds with various habitat and trophic preferences. The highest geometric mean concentrations of Hg were found in large piscivorous birds such as Cormorant and Grey Heron. The maximum mercury levels were noted for individuals of White-tailed Eagle and Great Crested Grebe. Significant differences in renal mercury concentration between Sparrowhawk individuals were found in winter and in spring. Male Sparrowhawks generally accumulated rather more mercury in their kidneys than the females. Statistically significant differences in renal mercury concentration between males and females were also found for …
Birds And Small Urban Parks: A Study In A High Plateau City, Salvador Peris, Tinguaro Montelongo
Birds And Small Urban Parks: A Study In A High Plateau City, Salvador Peris, Tinguaro Montelongo
Turkish Journal of Zoology
The goal of the present study was to assess which variables influence the distribution of birds in urban parks. Twenty parks were studied in a city on the Spanish high plateau during the breeding season, and relationships among park characteristics, bird richness, and individual bird presences were established. The park area and tree cover accounted for 73.1% of the variation in bird richness. Although area size was the best predictor of species richness (65% of the variation), some species did not seem to be related to this variable but rather to others, such as vegetation and the degree of park …

Impacts Of Urbanisation On The Native Avifauna Of Perth, Western Australia, Robert Davis, C Gole, Jd Roberts
Research outputs 2012
Urban development either eliminates, or severely fragments, native vegetation, and therefore alters the distribution and abundance of species that depend on it for habitat. We assessed the impact of urban development on bird communities at 121 sites in and around Perth, Western Australia. Based on data from community surveys, at least 83 % of 65 landbirds were found to be dependent, in some way, on the presence of native vegetation. For three groups of species defined by specific patterns of habitat use (bushland birds), there were sufficient data to show that species occurrences declined as the landscape changed from variegated …

Movement Ecology Of An Intercontinental Migratory Bird During Spring Stopover, Emily Beth Cohen
Movement Ecology Of An Intercontinental Migratory Bird During Spring Stopover, Emily Beth Cohen
Dissertations
Movement ecology is a component of nearly all aspects of animal behavior and an animal’s decision to move is likely influenced by a complex combination of exogenous and endogenous factors. Therefore, an examination of the causes and consequences of organismal movement provides a conceptual framework for understanding complex behavioral strategies. My dissertation research is focused on the movement ecology of an intercontinental migratory songbird during spring migration. I adopted experimental approaches to study the factors influencing how a songbird migrant, red-eyed vireos (Vireo olivaceus), makes decisions in unfamiliar landscapes from the initiation of spring stopover.
I simulated the …

Disturbance As Restoration In The Intermountain Sagebrush Steppe: Effects On Non Target Bird Species, Russell Edward Norvell
Disturbance As Restoration In The Intermountain Sagebrush Steppe: Effects On Non Target Bird Species, Russell Edward Norvell
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Changes in shrubsteppe passerine bird habitat associations in response to disturbance were investigated at multiple temporal and spatial scales. Spatial measures incorporated the effects of area at different ecological scales (nest site, territory, and landscape) to include ecologically meaningful extents. Temporal measures included seasonal and annual effects, and were designed to detect lagged responses should they occur. Local-to-landscape scale effects of mechanical restoration treatments on local extirpation and abundances of nine species indicated most were insensitive to changes in habitat quality, while abundance models showed only broad declines. Changing the availability of nesting habitat on both the attractiveness and quality …

Left-Sided Directional Bias Of Cloacal Contacts During House Sparrow Copulations, Karen B. Nyland, Michael P. Lombardo, Patrick A. Thorpe
Left-Sided Directional Bias Of Cloacal Contacts During House Sparrow Copulations, Karen B. Nyland, Michael P. Lombardo, Patrick A. Thorpe
Peer Reviewed Publications
Most female birds have only a left ovary and associated oviduct. The entry to the oviduct is on the left side of the urodeum of the cloaca. This arrangement may favor males that mount females from the left during copulation if it results in sperm being placed closer to the opening of the oviduct. Therefore, we predicted a left-sided directional bias of cloacal contacts during House Sparrow (Passer domesticus) copulations. Cloacal contacts from the left outnumbered those from the right 74 to 25 (3:1) during 25 bouts of copulation at 11 House Sparrow nests. While this pattern suggests …
