Mammalian & Avian Community Response To African Elephant (Loxodonta Africana) Habitat Modification In Southeastern Kenya, Dakota Vaccaro
Mammalian & Avian Community Response To African Elephant (Loxodonta Africana) Habitat Modification In Southeastern Kenya, Dakota Vaccaro
Masters Theses & Specialist Projects
African elephants (Loxodonta africana) play a significant role in the modification of their habitat, foremost by decreasing woody vegetation cover and density and in some parts of Africa high elephant densities damage small sanctuaries and preserves. For wildlife that depend on forested patches, this increased modification could lead to displacement and/or decreases in abundance. If suitable habitat is not available elsewhere, elephants and other wildlife may move closer to humans in search of resources, which can result in increased human-wildlife conflict. Evaluating this impact was one of the goals of the Elephants and Sustainable Agriculture in Kenya (ESAK) …

Remembering Paul Johnsgard, Linda R, Brown, Josef Kren
Zea E-Books Collection
Paul A. Johnsgard (1931–2021) was a friend of many, an artist, prolific author, teacher, and humble admirer of all living creatures. It was impossible to find someone at Nebraska Audubon Society or Nebraska Ornithologists’ Union meetings who did not know Paul Johnsgard. His more than 100 published books made him known not just in a community of ornithologists, birdwatchers, and bird lovers in the United States but also abroad. He was a world-renowned ornithologist and naturalist who remained deeply embedded in his local culture and its prairie environment.
We invited about 75 people to write a short memory of Paul. …
Lifetime Inclusive Fitness Effects Of Cooperative Polygamy In The Acorn Woodpecker, Walter D. Koenig, Sahas Barve, Joseph Haydock, Eric L. Walters
Lifetime Inclusive Fitness Effects Of Cooperative Polygamy In The Acorn Woodpecker, Walter D. Koenig, Sahas Barve, Joseph Haydock, Eric L. Walters
Biological Sciences Faculty Publications
Although over 50 y have passed since W. D. Hamilton articulated kin selection and inclusive fitness as evolutionary explanations for altruistic behavior, quantifying inclusive fitness continues to be challenging. Here, using 30 y of data and two alternative methods, we outline an approach to measure lifetime inclusive fitness effects of cooperative polygamy (mate-sharing or cobreeding) in the cooperatively breeding acorn woodpecker Melanerpes formicivorus. For both sexes, the number of offspring (observed direct fitness) declined while the number of young parented by related cobreeders (observed indirect fitness effect) increased with cobreeding coalition size. Combining these two factors, the observed inclusive …
Drivers And Direct Impacts Of Lean Mass Dynamics On The Stopover Ecology And Migratory Pace Of Nearctic-Neotropical Migrant Songbirds In Spring, Mariamar Gutierrez Ramirez
Drivers And Direct Impacts Of Lean Mass Dynamics On The Stopover Ecology And Migratory Pace Of Nearctic-Neotropical Migrant Songbirds In Spring, Mariamar Gutierrez Ramirez
Doctoral Dissertations
Annual migration in songbirds is one of the most demanding life-history stages. It represents a period of high mortality, yet there is still much unknown about the ecological correlates that influence its successful completion. After long non-stop migratory flights, birds require a stopover period to rest and replenish depleted energy reserves. Birds use fat as the primary fuel to power long-distance flights. However, birds also burn lean tissue, which results in significant reductions in muscle and organ masses. The discovery and quantification of lean mass catabolism represented a paradigm shift in migration ecology because non-fat components were thought to remain …
Social Communication Across Reproductive Boundaries: Hormones And The Auditory Periphery Of Songbirds And Frogs, M. D. Gall, Alexander T. Baugh, J. R. Lucas, M. A. Bee
Social Communication Across Reproductive Boundaries: Hormones And The Auditory Periphery Of Songbirds And Frogs, M. D. Gall, Alexander T. Baugh, J. R. Lucas, M. A. Bee
Biology Faculty Works
Most animals experience reproductive transitions in their lives; for instance, reaching reproductive maturity or cycling in and out of breeding condition. Some reproductive transitions are abrupt, while others are more gradual. In most cases, changes in communication between the sexes follow the time course of these reproductive transitions and are typically thought to be coordinated by steroid hormones. We know a great deal about hormonal control of communication behaviors in birds and frogs, as well as the central neural control of these behaviors. There has also been significant interest in the effects of steroid hormones on central nervous system structures …

Vignette 03: Birds Of The Salish Sea, Rob Butler
Institute Publications
The significance of the Salish Sea comes into focus when we look at the diversity and abundance of its birds and mammals, some of which are globally, continentally, and nationally important. Of particular importance is the diversity and abundance of species on the Fraser River Delta. There are more species of birds on the delta than any comparable area in Canada, and nearly half of all 550 species of birds reported for British Columbia have been seen on the delta. Despite all that has been learned about marine birds and mammals, large areas of the Salish Sea in Canada have …
Blue Jay Call Profile In Disparate Environments, Daniel A. Gesualdi
Blue Jay Call Profile In Disparate Environments, Daniel A. Gesualdi
Pell Scholars and Senior Theses
Many species of birds have been observed to develop higher-pitched calls in urban environments; however local Blue Jays are unstudied (Mockford and Marshall, 2009). The urban environment's high noise pollution imposes a significant fitness challenge; then, the urban Jay calls will be different (higher) than rural Jay(Parris and Schneider, 2009). A series of recordings were taken in rural and urban environments; it was clear that there is a significant increase in maximum and minimum kHz in urban jays than rural jays. These results suggest that blue jays alter their calls to accommodate the environmental factors in urban settings similar to …

Occurrence Of Ticks (Acari: Ixodidae) On Birds In Northwestern Lower Michigan, 2011-2019, William C. Scharf, Lisa Aukland, Gary W. Shugart, Sarah A. Hamer
The Great Lakes Entomologist
Abstract
Monitoring tick infestation of wildlife provides baseline tick
occurrence data that may have human or animal health implications. We collected 312 ticks of four species from 5,122 birds of 93 species while monitoring bird migration during 15 fall and spring seasons between 2011 and 2019 in the northern Lower Peninsula of Michigan. Twenty-seven of 93 bird species hosted ticks with an overall prevalence (=at least one tick) of 3.6% (185/5,122). Median burden was one tick/per infested bird with a range of 1-16 ticks per infested bird. Tick species collected were primarily Haemaphysalis leporispalustris (Packard) and Ixodes scapularis Say, with …

Living Shorelines Achieve Functional Equivalence To Natural Fringe Marshes Across Multiple Ecological Metrics, Robert Isdell, Donna M. Bilkovic, Amanda Guthrie, Molly Mitchell, Randolph M. Chambers, Matthias Leu, Carl Hershner
VIMS Articles
Nature-based shoreline protection provides a welcome class of adaptations to promote ecological resilience in the face of climate change. Along coastlines, living shorelines are among the preferred adaptation strategies to both reduce erosion and provide ecological functions. As an alternative to shoreline armoring, living shorelines are viewed favorably among coastal managers and some private property owners, but they have yet to undergo a thorough examination of how their levels of ecosystem functions compare to their closest natural counterpart: fringing marshes. Here, we provide a synthesis of results from a multi-year, large-spatial-scale study in which we compared numerous ecological metrics (including …

The Abundant-Centre Is Not All That Abundant: A Comment To Osorio-Olvera Et Al. 2020, Tad Dallas, Samuel Pironon, Luca Santini
Faculty Publications
Species abundance is expected to decrease from the centre towards the edge of their ecological niches (abundant niche-centre hypothesis). Recently, Osorio-Olvera et al. (2020) reported strong support for the abundant niche-centre relationship in North American birds. We demonstrate here that methodological decisions strongly affected perceived support. Avoiding these issues casts doubt on conclusions by Osorio-Olvera et al. and the putative support for the abundant nichecentre hypothesis in North American birds.
Several Vegetation Characteristics Affect Reproductive Success Of Grassland Birds At A Restored, Warm-Season Grassland In Central Georgia, Kayla B. Allen
Several Vegetation Characteristics Affect Reproductive Success Of Grassland Birds At A Restored, Warm-Season Grassland In Central Georgia, Kayla B. Allen
Biology Theses
Grassland birds are experiencing major population declines due to habitat loss and fire suppression throughout North America. Large-scale grassland restoration efforts are ongoing, but there is little data on breeding bird productivity on restored habitats, nor on the impact of specific vegetation characteristics on reproductive output. Since 2005, agriculture fields at Panola Mountain State Park, GA have been undergoing restoration to warm-season grasslands; however, up until now there has been no monitoring of nest success or productivity. The goals of this project are to 1) quantify reproductive success and 2) determine which vegetation characteristics are associated with reproductive success. From …
Effects Of Pharmacologically-Induced Sleep Loss On Parental Care In Arctic-Breeding Songbirds, Wesley Payette
Effects Of Pharmacologically-Induced Sleep Loss On Parental Care In Arctic-Breeding Songbirds, Wesley Payette
Masters Theses & Specialist Projects
Sleep loss is well known to impair cognitive function, immunological responses, and general well-being in humans. However, sleep requirements in mammals and birds may vary dramatically, especially with changes in environment. In circumpolar regions with continuous light, sleep requirements may be little, particularly in breeding birds. The effects of sleep loss on several fitness parameters were examined in two species of Arctic-breeding passerine birds: Lapland longspurs (Calcarius lapponicus) and snow buntings (Plectrophenax nivalis). Adult males were implanted during the nestling phase (4 days post-hatch) with osmotic pumps containing an anti-narcolepsy drug, modafinil, to extend the active period for 72 h. …

The Allometry Of Daily Energy Expenditure In Hummingbirds: An Energy Budget Approach, Anushu Shankar, Donald R. Powers, Liliana M. Dávalos, Catherine H. Graham
Faculty Publications - Department of Biological & Molecular Science
1. Within-clade allometric relationships represent standard laws of scaling between energy and size, and their outliers provide new avenues for physiological and ecological research. According to the metabolic-level boundaries hypothesis, metabolic rates as a function of mass are expected to scale closer to 0.67 when driven by surface-related processes (e.g. heat or water flux), while volume-related processes (e.g. activity) generate slopes closer to one.
2. In birds, daily energy expenditure (DEE) scales with body mass (M) in the relationship log (DEE)=2.35+0.68×log (M), consistent with surface-level processes driving the relationship. However, taxon-specific patterns differ from the scaling slope of all birds. …
Investigating Dispersal Ability To Infer Diversification In The Birds Of Madagascar, Robert D. Lauer
Investigating Dispersal Ability To Infer Diversification In The Birds Of Madagascar, Robert D. Lauer
Master's Theses
The objective of this study was to investigate whether dispersal ability, as measured by a proxy of hand-wing index 2, influenced diversification of the birds of Madagascar at two scales. Madagascar is home to several avian lineages that have diversified greatly while other lineages are only represented by a single species. a key question in evolutionary biology is why some of these lineages diversified while others did not. One way to address this is to examine what features of these lineages promotes their diversification. Recent studies have focused on the relative importance of dispersal ability to diversification at the continental …

Prenatal Aromatase Inhibition Alters Postnatal Immunity In Domestic Chickens (Gallus Gallus), Jeff W. Simkins, Abby E. Joseph, Frances Bonier, Z. Morgan Benowitz-Fredericks
Faculty Journal Articles
In birds, exposure to exogenous testosterone during embryonic development can suppress measures of immune function; however, it is unclear whether these effects are due to direct or indirect action via aromatization. Estradiol (E2) is synthesized from testosterone by the enzyme aromatase, and this conversion is a necessary step in many signaling pathways that are ostensibly testosterone-dependent. Many lines of evidence in mammals indicate that E2 can affect immune function. We tested the hypothesis that some of the immunomodulatory effects observed in response to in ovo testosterone exposure in birds are mediated by conversion to E2 by aromatase, by using fadrozole …

Pedigree Validation Using Genetic Markers In An Intensively-Managed Taonga Species, The Critically Endangered Kakī (Himantopus Novaezelandiae), Ashley Overbeek, Stephanie Galla, Liz Brown, Simon Cleland, Cody Thyne, Richard Maloney, Tammy Steeves
Biology Faculty Publications and Presentations
Many species recovery programmes use pedigrees to understand the genetic ancestry of individuals to inform conservation management. However, incorrect parentage assignment may limit the accuracy of these pedigrees and subsequent management decisions. This is especially relevant for pedigrees that include wild individuals, where misassignment may not only be attributed to human error, but also promiscuity (i.e. extra-pair parentage) or egg-dumping (i.e. brood parasitism). Here, we evaluate pedigree accuracy in the socially monogamous and critically endangered kakī (black stilt, Himantopus novaezelandiae) using microsatellite allele-exclusion analyses for 56 wild family groups across three breeding seasons (2014–2016, n= 340). We identified …

Investigating The Avian Species Composition, Diversity, And Abundance Of Engelhorn Pond, Kiana Rose
Undergraduate Honors Theses
Central Washington University’s Engelhorn Pond contains important habitats for many organisms, particularly migratory birds, and is a valuable resource for students. However, little information is available about the wildlife inhabiting the pond. The pond’s discrete location means that many people are unaware of its existence. In addition, the pond is threatened by a number of anthropogenic sources, including chemical runoff, garbage, and feral cats. By using point counts, a common ornithological survey technique, I recorded the bird species present at the pond during all seasons of the year. I collected data using point counts during 13 visits from June of …

Complex Gene Loss And Duplication Events Have Facilitated The Evolution Of Multiple Loricrin Genes In Diverse Bird Species, Anthony C. Davis, Matthew J. Greenwold, Roger H. Sawyer
Faculty Publications
The evolution of a mechanically resilient epidermis was a key adaptation in the transition of amniotes to a fully terrestrial lifestyle. Skin appendages usually form via a specialized type of programmed cell death known as cornification which is characterized by the formation of an insoluble cornified envelope (CE). Many of the substrates of cornification are encoded by linked genes located at a conserved genetic locus known as the epidermal differentiation complex (EDC). Loricrin is the main protein component of the mammalian CE and is encoded for by a gene located within the EDC. Recently, genes resembling mammalian loricrin, along with …
Where Birds Chill: An Assessment Of The Habitat Preferences Of Birds Overwintering In Hudson Valley Forests, Elizabeth Claire Axley
Where Birds Chill: An Assessment Of The Habitat Preferences Of Birds Overwintering In Hudson Valley Forests, Elizabeth Claire Axley
Senior Projects Spring 2019
Many avian species overwinter in eastern North America; however, studies on bird populations are rarely undertaken during this critical survival time, and little is known as to their habitat preferences and foraging behavior. In this observational study, we performed a survey of birds overwintering in the Hudson Valley’s temperate, primarily-deciduous forests, assessing avian populations’ habitat preferences through the vegetative structural variables surrounding overwintering birds as they forage. Our results suggest that high canopy cover is critically important to predicting overwintering bird occupancy on a microhabitat scale. Moreover, overwintering birds preferentially occupy forest plots not dominated by sugar maples, in spite …

Human–Wildlife Interactions
Human–wildlife conflicts occur when wildlife has an adverse effect on human activities (e.g., predation of livestock, crop raiding). These conflicts are increasing, particularly in areas surrounding natural protected areas, where villagers engage in subsistence agriculture. Crop damage may cause farmers to retaliate and harm wildlife species considered responsible for the damage. Among the factors that determine the intensity of the conflict are the frequency of the damage and the amount of biomass consumed relative to the perceptions, values, and cultural history of the farmers affected. To better understand the conflicts between farmers and wildlife, we compared farmer perceptions of wildlife …

Journal of the Arkansas Academy of Science
Important observations of natural history often go unreported because they are not part of larger studies, but small details can provide insights that lead to interesting questions about ecological relationships or environmental change. We have compiled recent important observations of distribution, deformities, foods, parasites, and reproduction of various vertebrates. Included are a new record of Lake Sturgeon (Acipenser fulvescens), a new size record of mudpuppy (Necturus louisianensis), and a second observation of bilateral gynandromorphism in a Northern Cardinal (Cardinalis cardinalis). These unique observations continue to grow knowledge of vertebrate biology in Arkansas.
Avian Thermoregulation In The Heat: Resting Metabolism, Evaporative Cooling And Limits To Activity In Sonoran Desert Birds, Eric Smith
Biology ETDs
Birds in subtropical deserts face significant thermoregulatory challenges as environmental temperatures regularly exceed avian body temperature. To understand the differing susceptibility of desert birds to increasing temperatures, this dissertation initially examined thermoregulatory performance in seven passerine bird species varying in body mass from 10 to 70g – Lesser Goldfinch, House Finch, Pyrrhuloxia, Cactus Wren, Northern Cardinal, Abert’s Towhee and Curve-billed Thrasher – and three larger Sonoran Desert nesting bird species – Mourning Dove (104 g), White-winged Dove (147 g) and Gambel’s Quail (161 g). Daytime resting metabolism, evaporative water loss and real-time body temperature were measured using flow-through respirometry at …

Ecosystems experience change due to both natural causes and anthropogenic impact such as habitat fragmentation and climate change. Avian species are used as habitat indicators to observe ecosystem integrity and have been observed to experience changes in biodiversity due to anthropogenic impact. This study examines the temporal and spatial changes of avian biodiversity in Acadia National Park. We seek to understand (1) how the alpha diversity has changed over time on Mount Desert Island and Schoodic Peninsula, (2) how beta diversity has changed over time for Mount Desert Island and Schoodic Peninsula (3) how the Schoodic Woods Campground can be …

Cryptic Diversification Of Two Widespread Species In Madagascar, Lynika Sharlice Strozier
Master's Theses
Using phylogenetic and phylogeographic tools to uncover hidden diversity within the genus Newtonia in Madagascar
Madagascar is known for its rich biodiversity and high level of endemic species that are found nowhere else. Cryptic diversification, defined as genetically and evolutionarily distinct species that are hard to detect because they are morphologically indistinguishable from their closest relatives, has been hypothesized to occur in many groups on Madagascar. Currently it is unclear to what extent this phenomenon occurs in birds because only a few studies have been conducted. My study examined the phylogenetic and phylogeographic patterns within a songbird genus, Newtonia, that …

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 …

The abundance and the presence of common cuckoos Cuculus canorus have been shown to predict species richness of birds across Europe, while there are no such analyses available for other continents where species richness of parasitic cuckoos is larger. Here, we tested whether species richness of birds increased with the number of cuckoo species in two study areas in China and one in Japan. We also tested whether species richness of birds can be predicted by the number of cuckoo individuals. Furthermore, we compared the strength of association between overall bird species richness and species richness of cuckoos, Paridae, Corvidae, …
