Impacts Of Invasive Rats On Hawaiian Cave Resources, Francis G. Howarth, Fred D. Stone

International Journal of Speleology

Although there are no published studies and limited data documenting damage by rodents in Hawaiian caves, our incidental observations during more than 40 years of surveying caves indicate that introduced rodents, especially the roof rat, Rattus rattus, pose significant threats to vulnerable cave resources. Caves, with their nearly constant and predictable physical environment often house important natural and cultural features including biological, paleontological, geological, climatic, mineralogical, cultural, and archaeological resources. All four invasive rodents in Hawai‘i commonly nest in cave entrances and rock shelters, but only the roof rat (Rattus rattus) habitually enters caves and utilizes areas …

Insights About Diversity Of Tetrabothriidae (Eucestoda) Among Holarctic Alcidae (Charadriiformes): What Is Tetrabothrius Jagerskioeldi?, Eric P. Hoberg, Kaylen Marie Soudachanh

MANTER: Journal of Parasite Biodiversity

Tetrabothriid cestodes are characteristic helminths that infect species of seabirds globally. We begin with the exploration of the diversity of tapeworms of the genus Tetrabothrius Rudolphi, 1819 (Eucestoda: Tetrabothriidae), some of which are distributed among seabirds of the family Alcidae (Charadriiformes) at boreal to higher latitudes of Holarctic seas. During the course of 2 decades of field inventory from 1975 through the early 1990s (in addition to earlier collections assembled by Robert L. Rausch and colleagues in Alaska initiated in the late 1940s), an extensive series of tapeworm specimens attributable to species of Tetrabothrius was recovered from seabirds across the …

Dynamics Of Avian Elevational Ranges Reveal Hidden Evolutionary Forces, Chauncey R. Gadek

Biology ETDs

The distribution of life across the Andes mountains reflects historical elevational-range contraction and expansion. Whereas contraction implies specialization, expansion requires overcoming hidden barriers. Three eco-evolutionary phenomena may drive patterns in rates of elevational range evolution: (1) The Dobzhansky-MacArthur Phenomenon (DMP) predicts lower rates of upward expansion with harsher physical conditions, while downward expansion increases with lower diversity; (2) the evolutionary tendency toward specialization predicts contraction increases when ranges are broad; and (3) natural selection for respiratory performance could suppress expansion across mid-elevations due to gene-environment mismatch. We modeled elevational range shifts of Neotropical landbirds. Contrary to the DMP, upward expansion …

A Preliminary Study On Population Of Some Passeriformes At Marala Head, Zahid Bhatti, Fakhra Nazir, Asad Ghufran

Journal of Bioresource Management

Passerines are perching birds of order Passeriformes representing half of the diversity of birds (Sibley and Monroe, 1990). There are total 6,600 species identified under 140 families declaring Passeriformes as the largest order of birds. Three hundred and thirteen species of Passeriformes were reported by Roberts (1992) from Pakistan but according to check list of birds of Pakistan there are more than 400 species of Passeriformes in Pakistan (Clements, 2019). They have significant ecological importance in an ecosystem and are mostly omnivores except the shrikes which are carnivorous. This study was done to form a preliminary checklist of Passeriformes at …

Andean Condor Cliff And Parental Care Behavior: A Behavioral Study Of A Chick And His Free-Living Parents On The Peñón Del Isco, Ecuador, Ellie Cohn

Independent Study Project (ISP) Collection

Andean condors (Vultur gryphus) are a Near Threatened species of New World Vulture found throughout the Andes region of South America. Their population has been significantly diminished in the country of Ecuador due to threats primarily related to habitat loss and persecution by humans. High chick and juvenile mortality also threaten populations and as a result, investigation of wild Andean condors’ cliff behavior and parental care are necessary in order to develop informed and effective conservation management plans. A 22-day observational study was conducted, monitoring a known breeding pair of Andean condors and their approximately three-month-old male chick on the …

Climate Change Impacts On Bird Communities Vary Throughout Cities In Kansas, Lindsey Williams, Christine Brodsky

Posters

It is important to study climate change’s impacts on biodiversity in order to find a solution before the effects on wildlife are irreversible. Our research objective for this project was to determine if climate change affected long-term bird trends in urban and rural areas throughout Kansas. Our hypothesis was that climate change will decrease bird abundance and species richness because altered climate patterns like storms, droughts, and heat waves, may cause a decrease in suitable habitat. We would expect these trends to be strongest in cities, due to the urban heat island effect. The methods used for this project included …

Avian Upsloping In The Tropics: Myioborus Miniatus And Myioborus Torquatus Abundance In Different Altitudinal Ranges In Boquete, Chiriquí, Panama, Julie Yoon

Independent Study Project (ISP) Collection

Direct and indirect effects of warming global temperatures due to climate change are known to cause upwards shifts of the altitudinal ranges of some avian species. Most susceptible to this trend and at risk of riding the “escalator to extinction” are endemic species in tropical montane cloud forests, such as Myioborus torquatus. There are abiotic factors, like temperature, and biotic interactions, such as the presence of its altitudinal neighbor Myioborus miniatus, that limit the altitudinal range of this bird species in the Neotropics. This study measured abundance of M. miniatus and M. torquatus populations at different altitudinal ranges by point …

Iceland's Migratory Birds In Changing Environmental Conditions: An Interactive Synthesis, Frances J. Duncan

Independent Study Project (ISP) Collection

Human-driven changes to environmental conditions alter the habitats, behaviors, and migration patterns of migratory species. Changes in temperature, vegetation, and precipitation are just some of the factors contributing to shifts in phenology, demography, and distribution of migratory birds. These changes are driven by anthropogenic climate change and amplified by human land-use change, and are especially intense at high latitudes. This project creatively communicates the effects of environmental changes on three species of migratory birds in Iceland—the northern wheatear, the Greenland white-fronted goose, and the black-tailed godwit—using principles of storytelling and game design. The resulting interactive product is a game that …

Quiscalus Mexicanus Vocalization Pitch And Traffic Noise In Breeding Populations Along The Cinta Costera Highway And In Downtown Gamboa, Panamá, Benjamin P. Gregory

Independent Study Project (ISP) Collection

Urbanization is one of the fastest-growing threats to the biodiversity of the planet, but not all animals are extirpated by the drastic environmental changes of urbanization, and many are even able to thrive in urban landscapes. Behavioral flexibility is often cited as one reason that successful urban animals can so rapidly adapt to a foreign environment with novel stressors. A well-studied example of urban behavioral flexibility is urban-living birds singing with higher-frequency songs in areas with high levels of traffic noise. The present study investigated this trend in Quiscalus mexicanus, an icterid bird with a huge vocal range, highly sexually …

Shade Trees Preserve Avian Insectivore Biodiversity On Coffee Farms In A Warming Climate, Sarah L. Schooler

Cal Poly Humboldt theses and projects

Coffee is an important export in many developing countries, with a global annual trade value of $100 billion. Climate change is projected to drastically reduce the area where coffee is able to be grown. Shade trees may mitigate the effects of climate change through temperature regulation for coffee growth, temperature regulation for pest control, and increase in pest-eating bird diversity. The impact of shade on bird diversity and microclimate on coffee farms has been studied extensively in the Neotropics, but there is a dearth of research in the Paleotropics. I examined the local effects of shade on bird presence and …

Bird Window Strikes On A College Campus: Mortality Estimates And Possible Mitigation, Antarius D. Mclain

College of Graduate Studies: Theses & Dissertations

Understanding the impact that human development has on wildlife populations is essential to preserving biodiversity. Bird populations are a good indicator of anthropogenic threats because they are sensitive to environmental change. Window strikes are a major source of mortality for bird populations. Studies have begun to monitor factors that cause window strikes and estimate the amount of birds killed annually by strikes. However, these estimates can be greatly affected by site dependent variables and scavenging of carcasses. My study addresses this issue by answering four questions: First, how many birds are killed annually on campus? Second, what factors complicate making …

Cerulean Warbler (Setophaga Cerulea) And Associated Species Response To Operational Silviculture In The Central Appalachian Region, Gretchen Emily Nareff

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this study, I assessed the response of Cerulean Warblers (Setophaga cerulea) and 5 additional songbird species to timber harvests prescribed through operational silviculture. The research took place in relatively contiguous mature deciduous forests in 4 states in the central Appalachian region—Kentucky, Pennsylvania, Virginia, and West Virginia, USA.

For the first part of the study, I collected Cerulean Warbler abundance and territory data through point counts and territory mapping, respectively. I used the point count data to model Cerulean Warbler abundance pre- and post-harvest at 5 study areas (Kentucky [n=1], Virginia [n=2], West Virginia [n=2]) and post-harvest at …

Avian Occupancy Dynamics And Canada Warbler (Cardellina Canadensis) Environmental Correlates On A Central Appalachian Elevation Gradient In West Virginia, Gordon W. Dimmig

Graduate Theses, Dissertations, and Problem Reports (ETD)

Mountains are important areas for avian diversity and conservation since they have steep elevational and environmental gradients. In the central Appalachian Mountains, several songbird species have trailing edge populations that are restricted to high elevations. Climate change and other factors can cause species distributions to change, which is of particular concern for birds in restricted trailing edge populations. Additionally, the Canada Warbler (Cardellina canadensis) breeds throughout the Appalachian Mountains and is species of conservation concern due to range-wide population declines. For this project, I used avian point count data from the central Appalachian Mountains to: (1) evaluate the …

Microplastics In Full View: Birds As Bioindicators Of Malta's Coastal Ecosystem Health, Dalton Brauer

Masters Theses, 2010-2019

Plastic pollution has recently become a widely studied topic, yet research on microplastics has remained lacking for specific geographic regions. Microplastics are small plastics resulting from degradation or the dumping of raw material and can lead to deleterious impacts on the coastal marine environment and its organisms. To assess Malta’s coastal environmental health, water birds (inshore, offshore and pelagic species) were used as bioindicators by assessing the presence and abundance of plastic within their stomach contents. The project hoped to fill some of the current gaps in knowledge on microplastics within Malta by creating a working baseline, as well as …

Relationships Among Biodiversity Dimensions Of Birds In Nebraska, Nadejda Mirochnitchenko

School of Natural Resources: Dissertations, Theses, and Student Research

Biological diversity, or biodiversity, is a multi-dimensional concept that can be decomposed to measure information about taxonomic, phylogenetic, and functional variation within communities. Although the dimensions of biodiversity are interrelated, the assumption that measuring one dimension of diversity can inform about patterns in another dimension does not necessarily follow from theory or empirical study. The relationships among biodiversity dimensions is not well understood, nor how differences among dimensions could influence conservation decision making. Using the avian community as a study system, we explored the relationships of breadth metrics from the taxonomic, phylogenetic, and functional dimensions among each other and across …

Gulls, Martin S. Lowney, Scott F. Beckerman, Scott C. Barras, Thomas W. Seamans

Wildlife Damage Management Technical Series

Abundant gull (Figure 1) populations in North America have led to a variety of conflicts with people. Gulls cause damage at aquaculture facilities and other properties, and often collide with aircraft. Their use of structures on and near water results in excessive amounts of bird droppings on boats and docks. Their presence near outdoor dining establishments, swimming beaches, and recreational sites can lead to negative interactions with people. Large amounts of gull fecal material pollutes water and beaches resulting in drinking water contamination and swim bans. A combination of dispersal techniques, exclusion and limited lethal control may reduce damage to …
