Population Response To Climate Change: Wintering Strategy Has Carryover Effects On The Timing Of Nest Initiation And Mate Choice In A Partial Migrant, The American Kestrel (Falco Sparverius), Alexandra Marie Anderson

Boise State University Theses and Dissertations

The ability of a population to respond to climate change will depend on phenotypic plasticity, adaptation, or both. Bird populations have already responded to warming temperatures by shifting their distributions, adjusting migration distance and timing, and breeding earlier. A population of American kestrels (Falco sparverius) in southwestern Idaho has advanced its nesting by approximately 30 days, on average, in the last 30 years and this has been correlated with changes in winter climate. The mechanisms allowing for this shift, however, are not clearly understood. I investigated if assortative mating of wintering kestrels and non-wintering kestrels is accompanying to …

Sink Or Ecological Trap For Tree Swallows In Central Minnesota?, James T. Pathoulas, Nicole E. Noyes

Celebrating Scholarship & Creativity Day (2011-2017)

Background: An ecological trap is typically defined as a low-quality habitat, incapable of sustaining a population, which is preferred over a high quality habitat. Ecological traps may lead to species extinction in populations with 1) strict habitat requirements 2) minimal information about the habitat, and 3) low population size. Tree Swallows (Tachycineta bicolor) meet the former two of these criteria.

Methods: We monitored Tree Swallow (TS) nest boxes (n=90) at two ecologically similar sites A and B with similar occupancy rates. Site B has lower reproductive fitness —suggestive of an ecological trap. Binary logistic regression was used to …

A Morphological And Genetic Analysis Of Forensically Important Blow Flies, From Georgia: The Genus Lucilia, Katie S. Googe

Honors College Theses

Identification of Blow flies (Diptera: Calliphoridae) to species is important for estimating postmortem intervals, because insect species develop at different rates. Three Blow fly species in Georgia; Lucilia coeruleiviridis, L. cuprina, and L. sericata are similar morphologically, making identification difficult. Furthermore, the status of L. cuprina is in doubt; this species may be a complex of true L. cuprina, and L. cuprina x L. sericata hybrids. The objective of this study was to survey the Georgia Blow fly community and validate the statuses of L. coeruleiviridis, L. cuprina, and L. sericata, through morphological and …

Birds In Peatswamp At Klias Forest Reserve And Environs, Sabah, Malaysian Borneo, Frederick H. Sheldon, Geoffrey Davison, Anna Wong, Robert G. Moyle

Occasional Papers of the Museum of Natural Science, Louisiana State University

Periodically from 1998-2004, we surveyed birds in the Klias Forest Reserve, which is one of the last remaining pockets of peatswamp in western Sabah. We report here on those surveys. We also review prior work on birds in peatswamp and swamp forest in the Klias-Sipitang region of Sabah as it relates to the conservation of habitat and birds specialized on peatswamp. Peatswamp forest is in jeopardy from development and fires throughout Borneo, and particularly in the Malaysian State of Sabah, which had very little to start. Peatswamp in the Klias area is of particular importance for conservation and bird watching …

Determination Of The Ecological Condition Of Benthic Communities Affected By Polycyclic Aromatic Hydrocarbons In The Elizabeth River, Chesapeake Bay, Usa, Adam M. Webb

Biological Sciences Theses & Dissertations

The Southern Branch of the Elizabeth River, a tributary of Chesapeake Bay, has historically been polluted with hydrocarbon based industrial by-products. My study compared benthic community condition from two locations in the Southern Branch: the subtidal region near Money Point, historically affected by pollution of polycyclic aromatic hydrocarbons (PAHs), to a subtidal region near Blows Creek on the opposite shore that is putatively designated as unimpacted by P AH contamination. Samples from both study sites in the Southern Branch were compared to the benthic community condition of samples from the same habitat type designations collected as part of the Chesapeake …

Consequences Of A Refuge For The Predator-Prey Dynamics Of A Wolf-Elk System In Banff National Park, Alberta, Canada, Joshua F. Goldberg, Mark Hebblewhite, Jonathan M. Bardsley

Wildlife Biology Faculty Publications

Refugia can affect predator-prey dynamics via movements between refuge and non-refuge areas. We examine the influence of a refuge on population dynamics in a large mammal predator-prey system. Wolves (Canis lupus) have recolonized much of their former range in North America, and as a result, ungulate prey have exploited refugia to reduce predation risk with unknown impacts on wolf-prey dynamics. We examined the influence of a refuge on elk (Cervus elaphus) and wolf population dynamics in Banff National Park. Elk occupy the Banff townsite with little predation, whereas elk in the adjoining Bow Valley experience higher wolf predation. The Banff …

Evolutionary Relationships Of The Critically Endangered Frog Ericabatrachus Baleensis Largen, 1991 With Notes On Incorporating Previously Unsampled Taxa Into Large-Scale Phylogenetic Analyses, Karen Siu-Ting, David J. Gower, Davide Pisani, Roman Kassahun, Fikirte Gebresenbet, Michele Menegon, Abebe A. Mengistu, Samy A. Saber, Rafael O. De Sá, Mark Wilkinson, Simon P. Loader

Biology Faculty Publications

Background: The phylogenetic relationships of many taxa remain poorly known because of a lack of appropriate data and/or analyses. Despite substantial recent advances, amphibian phylogeny remains poorly resolved in many instances. The phylogenetic relationships of the Ethiopian endemic monotypic genus Ericabatrachus has been addressed thus far only with phenotypic data and remains contentious.

Results: We obtained fresh samples of the now rare and Critically Endangered Ericabatrachus baleensis and generated DNA sequences for two mitochondrial and four nuclear genes. Analyses of these new data using de novo and constrained-tree phylogenetic reconstructions strongly support a close relationship between Ericabatrachus and …

Notes On The Avifauna Of The Floodplain Forest Of The Rio Mamoré, Beni, Bolivia, With A Description Of The Juvenile Plumage Of Unicolored Thrush (Turdus Haplochrous) (Aves: Turdidae), Ryan S. Terrill, Miguel Angel Aponte Justiniano, Michael G. Harvey, Glenn F. Seeholzer, Rosa Ines Strem

Occasional Papers of the Museum of Natural Science, Louisiana State University

Notes on the avifauna of the floodplain forest of the Rio Mamoré, Beni, Bolivia, with a description of the Juvenile plumage of Unicolored Thrush (Turdus haplochrous) – The floodplain forest along the Rio Mamoré is an isolated stretch of riverine forest in the matrix of flooded grassland and gallery forest of the Llanos de Moxos in the department of Beni, Bolivia and contains an understudied avifauna. This habitat potentially represents a stronghold for certain bird taxa. During Dec 2010-Jan 2011, we conducted daily audiovisual censuses, targeted collecting with shotguns, and general collecting with mist-nets for birds at a …

Did Pre-Clovis People Inhabit The Paisley Caves (And Why Does It Matter)?, Stuart J. Fiedel

Human Biology Open Access Pre-Prints

The date and processes of initial human colonization of the Americas are crucial issues for the understanding of human biological and cultural development. For example, Soares et al. (2009) cited the American archaeological record to validate their proposed revision of the human mitochondrial molecular clock. Their suggested mutation rate puts the date of rapid expansion of Native American clades at around 13,500–15,000 cal BP. Similarly, Poznik et al. (2013) have used the “high-confidence archaeological dating” of the initial peopling of the Americas to calibrate the rates of both Y-chromosome and mtDNA mutation and thereby to reconcile the ages of the …

Pedigree Structure And Kinship Measurements Of A Mid-Michigan Community: A New North American Population Isolate Identified, Joseph D. Bonner, Rachel Fisher, James Klein, Qing Lu, Ellen Wilch, Karen H. Friderici, Jill L. Elfenbein, Debra L. Schutte, Brian C. Schutte

Human Biology Open Access Pre-Prints

Previous studies identified a cluster of individuals with an autosomal recessive form of deafness that resides in a small region of mid-Michigan. We hypothesized that affected members from this community descend from a defined founder population. Using public records and personal interviews, we constructed a genealogical database that includes the affected individuals and their extended families as descendants of 461 settlers who emigrated from the Eifel region of Germany between 1836 and 1875. The genealogical database represents a 13-generation pedigree that includes 27,747 descendants of these settlers. Among these descendants, 13,784 are presumed living. Many of the extant descendants reside …

Effect Of Recent Historical Events On Migration And Isonymic Stratification Among The Rama Amerindians From Nicaragua, Norberto F. Baldi

Human Biology Open Access Pre-Prints

The Rama Amerindians from southern Nicaragua are one of few indigenous populations inhabiting the east coast and lowlands of southern Central America. Early 18th century ethnohistorical accounts depicted the Rama as a mobile hunter-gatherer and horticulturalists group dispersed in household units along southern Nicaraguan rivers. However, during the 19th and 20th centuries, Rama settlement patterns changed to aggregated communities due to increased competition for local resources resulting from non-indigenous immigration. This study’s objective was to discern the degree of relatedness between and within subdivisions of seven of these communities based on patterns of surname variation and genealogical data. We applied …

Celiac Disease As A Model For The Evolution Of Multifactorial Disease In Humans, Aaron Sams, John Hawks

Human Biology Open Access Pre-Prints

Celiac disease (CD) is a multifactorial chronic inflammatory condition that results in injury of the mucosal lining of the small intestine upon ingestion of wheat gluten and related proteins from barley and rye. Although the exact mechanisms leading to CD are not fully understood, the genetic basis of CD has been relatively well characterized. In this review we briefly review the history of discovery, clinical presentation, pathophysiology, and current understanding of the genetics underlying CD risk. Then, we discuss what is known about the current distribution and evolutionary history of genes underlying CD risk in light of other evolutionary models …

Lactase Persistence Variants In Arabia And In The African Arabs, Edita Priehodova, Abdelhay Abdelsawy, Evelyne Heyer, Viktor Cerny

Human Biology Open Access Pre-Prints

Lactase persistence (LP), the state enabling the digestion of milk sugar in adulthood occurs only in some human populations. The convergent and independent origin of this physiological ability in Europe and Africa is linked with animal domestication that had either started in both places independently or had spread from the Near East by acculturation. However, it has recently been shown that at least in its southern parts, the population of Arabia not only has a different LP-associated mutation profile than the rest of Africa and Europe but had also experienced an independent demographic expansion occurring before the Neolithic around the …

Notes On Bird Species In Bamboo In Northern Madre De Dios, Peru, Including The First Peruvian Record Of Acre Tody-Tyrant (Hemitriccus Cohnhafti), Michael G. Harvey, Daniel F. Lane, Justin Hite, Ryan S. Terrill, Sheila Figueroa Ramírez, Brian Tilston Smith, John Klicka, Walter Vargas Campos

Occasional Papers of the Museum of Natural Science, Louisiana State University

In the southwestern Amazon Basin, large areas of habitat are comprised predominantly of Guadua bamboo. Many bird species occur in or specialize on Guadua-dominated habitats, but little is known about the taxonomy, distribution, and evolutionary history of this avian assemblage. During 2011, we surveyed the surroundings of Iberia, an area with many large Guadua stands in the southern Peruvian Amazon. We found many Guadua specialist bird species and discovered a surprising Andean element to the local avifauna. We present information on Guadua specialists, Andean species, birds of open habitats, and avian migration and reproduction. We provide accounts for species …

Averting Lemur Extinctions Amid Madagascar's Political Crisis, Christoph Schwitzer, Russell Mittermeier, Steig Johnson, Giuseppe Donati, Mitchell Irwin, Heather Peacock, Jonah Ratsimbazafy, Josia Razafindramanana, Edward E. Louis, Lounes Chikhi, Ian C. Colquhoun, Jennifer Tinsman, Ranier Dolch, Marni Lafleur, Stephen Nash, Erik Patel, Blanchard Randrianambinina, Tove Rasolofoharivelo, Patricia C. Wright

Anthropology Publications

The most threatened mammal group on Earth, Madagascar’s five endemic lemur families (lemurs are found nowhere else), represent more than 20% of the world’s primate species and 30% of family-level diversity. This combination of diversity and uniqueness is unmatched by any other country—remarkable considering that Madagascar is only 1.3 to 2.9% the size of the Neotropics, Africa, or Asia, the other three landmasses where nonhuman primates occur. But lemurs face extinction risks driven by human disturbance of forest habitats. We discuss these challenges and reasons for hope in light of site-specific, local actions proposed in an emergency conservation action plan.

The Influence Of Topographic And Dynamic Cyclic Variables On The Distribution Of Small Cetaceans In A Shallow Coastal System, Marijke N. De Boer, Mark P. Simmonds, Peter J.H. Reijnders, Geert Aarts

Ecology Collection

The influence of topographic and temporal variables on cetacean distribution at a fine-scale is still poorly understood. To study the spatial and temporal distribution of harbour porpoise Phocoena phocoena and the poorly known Risso’s dolphin Grampus griseus we carried out land-based observations from Bardsey Island (Wales, UK) in summer (2001–2007). Using Kernel analysis and Generalized Additive Models it was shown that porpoises and Risso’s appeared to be linked to topographic and dynamic cyclic variables with both species using different core areas (dolphins to the West and porpoises to the East off Bardsey). Depth, slope and aspect and a low variation …

Warming, Soil Moisture, And Loss Of Snow Increase Bromus Tectorum’S Population Growth Rate, Aldo Compagnoni, Peter B. Adler

Green Canyon Environmental Research Area, Logan Utah

Climate change threatens to exacerbate the impacts of invasive species. In temperate ecosystems, direct effects of warming may be compounded by dramatic reductions in winter snow cover. Cheatgrass (Bromus tectorum) is arguably the most destructive biological invader in basins of the North American Intermountain West, and warming could increase its performance through direct effects on demographic rates or through indirect effects mediated by loss of snow. We conducted a two-year experimental manipulation of temperature and snow pack to test whether 1) warming increases cheatgrass population growth rate and 2) reduced snow cover contributes to cheatgrass’ positive response to …

Integrating Societal Perspectives And Values For Improved Stewardship Of A Coastal Ecosystem Engineer, Steven B. Scyphers, J. Steven Picou, Robert D. Brumbaugh, Sean P. Powers

University Faculty and Staff Publications

Oyster reefs provide coastal societies with a vast array of ecosystem services, but are also destructively harvested as an economically and culturally important fishery resource, exemplifying a complex social-ecological system (SES). Historically, societal demand for oysters has led to destructive and unsustainable levels of harvest, which coupled with multiple other stressors has placed oyster reefs among the most globally imperiled coastal habitats. However, more recent studies have demonstrated that large-scale restoration is possible and that healthy oyster populations can be sustained with effective governance and stewardship. However, both of these require significant societal support or financial investment. In our study, …
