Manipulation Of Same Sex Social Pair Bonds In Budgerigars, Melopsittacus Undulatus, Amanda M. Stilwell 2015 Otterbein University

Manipulation Of Same Sex Social Pair Bonds In Budgerigars, Melopsittacus Undulatus, Amanda M. Stilwell

Distinction Papers

Same sex pair bonding can be found throughout various animal species. These relationships can be common in monogamous species, especially when there is a lack of members of the opposite sex. Budgerigars, Melopsittacus undulatus, are a socially monogamous species, which create strong pair bonds but are also known to engage in extra pair copulations. When looking at an all-male flock of budgerigars, the question arises, are these bonds easily broken or disrupted by a third party individual. After determining seven pair bonds in a flock of 32 males, these pairs were removed from an aviary and placed in separate lab ...


Who Invented The Mule Deer (Odocoileus Hemionus)? On The Authorship Of The Fraudulent 1812 Journal Of Charles Le Raye, Neal Woodman 2015 USGS

Who Invented The Mule Deer (Odocoileus Hemionus)? On The Authorship Of The Fraudulent 1812 Journal Of Charles Le Raye, Neal Woodman

Neal Woodman

The captivity journal of Charles Le Raye was first published in 1812 as a chapter in A topographical description of the state of Ohio, Indiana Territory, and Louisiana, a volume authored anonymously by “a late officer in the U. S. Army”. Le Raye was purported to be a French Canadian fur trader who, as a captive of the Sioux, had travelled across broad portions of the Missouri and Yellowstone river drainages a few years before the Lewis and Clark expedition (1804–1806), and his account of the land, its people, and its natural resources was relied upon as a primary ...


New Records Of Merriam’S Shrew (Sorex Merriami) From Western North Dakota, Michael J. Shaughnessy Jr., Neal Woodman 2015 Northeastern State University, OK

New Records Of Merriam’S Shrew (Sorex Merriami) From Western North Dakota, Michael J. Shaughnessy Jr., Neal Woodman

Neal Woodman

Despite having a broad geographic distribution, Merriam’s Shrew (Sorex merriami Dobson 1890) is known from a relatively few, widely-scattered localities. In North Dakota, the species was known from only a single poorly-preserved specimen collected in 1913 near Medora. We recently collected two new specimens of Merriam’s Shrew from Billings and McKenzie counties in the western quarter of the state. These specimens confirm the presence of S. merriami in North Dakota and better define the northeastern edge of the species’ distribution.


Fish Out Of Salt Water: Smoltification In Subyearling Chinook Salmon From The Laurentian Great Lakes, Steve Sharron 2015 The University of Western Ontario

Fish Out Of Salt Water: Smoltification In Subyearling Chinook Salmon From The Laurentian Great Lakes, Steve Sharron

University of Western Ontario - Electronic Thesis and Dissertation Repository

The timing of smoltification in juvenile anadromous salmonids is important to ensure individuals match their preparedness with their migration timing and the optimal conditions in the environment. I performed the first study of smoltification in adfluvial juvenile Chinook salmon naturalized in the Laurentian Great Lakes. In a hatchery study, I found that juveniles from one of these populations have similar patterns of smoltification timing to individuals from anadromous populations. Their Na+/K+ ATPase activity, a common indicator or smolt status, peaked at 7.7 μmoles ADP/mg protein/hour on July 1 in freshwater. During the peak period, individual body ...

An Assessment Of South China Tiger Reintroduction Potential In Hupingshan And Houhe National Nature Reserves, China, Yiyuan Qin, Philip J. Nyhus, Courtney L. Larson, Charles J.W. Carroll, Jeff Muntifering, Thomas D. Dahmer, Lu Jun, Ronald L. Tilson 2015 Colby College

An Assessment Of South China Tiger Reintroduction Potential In Hupingshan And Houhe National Nature Reserves, China, Yiyuan Qin, Philip J. Nyhus, Courtney L. Larson, Charles J.W. Carroll, Jeff Muntifering, Thomas D. Dahmer, Lu Jun, Ronald L. Tilson

Philip J. Nyhus

Human-caused biodiversity loss is a global problem, large carnivores are particularly threatened, and the tiger (Panthera tigris) is among the world’s most endangered large carnivores. The South China tiger (Panthera tigris amoyensis) is the most critically endangered tiger subspecies and is considered functionally extinct in the wild. The government of China has expressed its intent to reintroduce a small population of South China tigers into a portion of their historic range as part of a larger goal to recover wild tiger populations in China. This would be the world’s first major tiger reintroduction program. A free-ranging population of ...


Annual Variation In Autumn Migration Phenology And Energetic Condition At A Stopover Site In The Western United States, Robert A. Miller, Jay D. Carlisle, Neil Paprocki, Gregory S. Kaltenecker, Julie A. Heath 2015 Boise State University

Annual Variation In Autumn Migration Phenology And Energetic Condition At A Stopover Site In The Western United States, Robert A. Miller, Jay D. Carlisle, Neil Paprocki, Gregory S. Kaltenecker, Julie A. Heath

Robert Miller

Climate change is having a dramatic effect on many migratory species. Changes in climate may lead to changes in food availability or other proximate cues that affect migratory behavior. We used 13 years (2000–2012) of data on songbird banding and raptor migration counts and captures during autumn migration in the intermountain West to evaluate whether regional temperature or precipitation or hemispheric climate indices predicted autumn migratory timing and energetic condition. We examined overall trends and evaluated the effects of diet and migratory distance on phenology and conditional responses. For the 13-year study period, no temperature, precipitation, or climate index ...


Sociality Increases Juvenile Survival After A Catastrophic Event In The Feral Horse (Equus Caballus), Cassandra M.V. Nuñez, James S. Adelman, Daniel I. Rubenstein 2015 Princeton University

Sociality Increases Juvenile Survival After A Catastrophic Event In The Feral Horse (Equus Caballus), Cassandra M.V. Nuñez, James S. Adelman, Daniel I. Rubenstein

Cassandra M.V. Nuñez

In several social species, adult associations have been linked to individual fitness. Less is known about offspring associations and the mechanisms by which they may influence fitness. We investigate the effects of sociality on juvenile survival in feral horses (Equus caballus). We use foal degree (number of associates) and foal weight (number of interactions) to assess sociality’s importance to foal survival of a catastrophic event, the gathering and removal of 40% of the horse population. We found that 1) foal degree was a better predictor of foal survival than was foal weight; 2) following the gather, foals with access ...


Variation In The Myosoricine Hand Skeleton And Its Implications For Locomotory Behavior (Eulipotyphla: Soricidae), Neal Woodman, Frank A. Stabile 2015 USGS

Variation In The Myosoricine Hand Skeleton And Its Implications For Locomotory Behavior (Eulipotyphla: Soricidae), Neal Woodman, Frank A. Stabile

Neal Woodman

Substrate use and locomotory behavior of mammals are typically reflected in external characteristics of the forefeet, such as the relative proportions of the digits and claws. Although skeletal anatomy of the forefeet can be more informative than external characters, skeletons remain rare in systematic collections. This is particularly true for the Myosoricinae (Eulipotyphla: Soricidae), a small clade of African shrews that includes both ambulatory forest shrews (Myosorex) and semifossorial mole shrews (Surdisorex). Most species in this subfamily have restricted distributions, and their behavior and ecology are mostly unstudied. To better understand the potential range of locomotory behavior among myosoricines, we ...

The Effect Of Mhc Diversity On Mate Choice In Captive African Penguins (Spheniscus Demersus), Kristen Schmid 2015 Otterbein University

The Effect Of Mhc Diversity On Mate Choice In Captive African Penguins (Spheniscus Demersus), Kristen Schmid

Distinction Papers

Background: The major histocompatibility complex (MHC) is highly polymorphic, functioning to maintain a proper immune system within all vertebrates. High diversity within exon 2 of the MHC class II gene has been linked to increases in both parasite resistance and overall fitness. Organisms mate with individuals who will provide them with a high diversity of MHC class II alleles. The role MHC diversity plays in mating of African penguins (Spheniscus demersus) has recently been a topic of debate due to their endangered species status. The purpose of this study is to determine the effects of MHC class II diversity on ...


Rafinesque’S Names For Western American Mammals, Including The Earliest Scientific Name For The Coyote (Canis Latrans Say, 1822), Based On The Apocryphal Journal Of Charles Le Raye, Neal Woodman 2015 USGS

Rafinesque’S Names For Western American Mammals, Including The Earliest Scientific Name For The Coyote (Canis Latrans Say, 1822), Based On The Apocryphal Journal Of Charles Le Raye, Neal Woodman

Neal Woodman

In 1817, the naturalist Constantine S. Rafinesque named nine new species of mammals from the American West, indicating the recently published journal of Charles Le Raye as the primary source for his descriptions. Le Raye was purported to be a French Canadian fur trader who, as a captive of the Sioux, had traveled across broad portions of the Missouri and Yellowstone river drainages a few years before the Lewis and Clark Expedition (1804–1806) traversed much of the same region. Le Raye’s journal was relied upon by generations of scholars as a valuable source documenting the native peoples and ...


Determinants Of Termite Species Taxonomic, Phylogenetic, And Functional Diversity In The Amazonian Forest, Cristian de Sales Dambros 2015 University of Vermont

Determinants Of Termite Species Taxonomic, Phylogenetic, And Functional Diversity In The Amazonian Forest, Cristian De Sales Dambros

Graduate College Dissertations and Theses

The distribution of species in space is determined by the species dispersal capacity, adaptation to environmental conditions, and response to predators and competitors. To determine the importance of dispersal limitation, environmental filtering, and species interactions on the distribution of species in the Brazilian Amazonian forest, I sampled termites in a large area of Brazil. I investigated patterns in species occurrence that could indicate competition and predation structuring termite communities, and analyzed the association of termite abundance and species richness with the density of ant predators. The spatial distribution of termites, and their association with climatic and edaphic conditions were also ...

The Role Of Islands In The Migration Of Bats Across Lake Erie And Lake Ontario: Lasiurus Borealis, Lasiurus Cinereus And Perimyotis Subflavus, Toby J. Thorne 2014 The University of Western Ontario

The Role Of Islands In The Migration Of Bats Across Lake Erie And Lake Ontario: Lasiurus Borealis, Lasiurus Cinereus And Perimyotis Subflavus, Toby J. Thorne

University of Western Ontario - Electronic Thesis and Dissertation Repository

Large bodies of water, such as the Great Lakes in North America, are potential barriers to migrating bats. Islands may be used as stopover sites by bats crossing the Great Lakes as stopover sites, or included in crossing routes to reduce the distance flown over open water. I predicted that stopover use by migrating bats would result in higher activity on Great Lakes islands during late-season migration than at mainland sites. I monitored acoustic activity at 11 sites across four locations in Ontario: Amherst and Pelee islands, Kingston and Pinery Provincial Park during the summer (June and July), and during ...


Low Temperature Tolerance Of Adult Drosophila Suzukii (Diptera: Drosophilidae), Ruth Jakobs 2014 The University of Western Ontario

Low Temperature Tolerance Of Adult Drosophila Suzukii (Diptera: Drosophilidae), Ruth Jakobs

University of Western Ontario - Electronic Thesis and Dissertation Repository

The crop pest Drosophila suzukii, native to Southeast Asia, has been found in Ontario since 2010. This raises concern with respect to it establishing permanent populations, however, little is known about its cold tolerance. I investigated the low-temperature tolerance, including phenotypic plasticity, of D. suzukii. While acclimation increased cold tolerance, there was no evidence of short-term cold-hardening. Chill coma occurs at -1.2 °C, which will limit winter activity. Cold shock decreased the reproductive output of females, but this negative effect may be mitigated by re-mating. Drosophila suzukii is chill-susceptible and 80 % of the flies die after exposure to -7 ...


Geographic Segregation And Evidence Of Density-Dependent Changes In Sex Ratios In An Abundant Colonial Waterbird, Brian S. Dorr, Katie C. Hanson-Dorr, Travis L. DeVault, Alban Guillaumet, Scott C. Barras 2014 USDA/WS/National Wildlife Research Center

Geographic Segregation And Evidence Of Density-Dependent Changes In Sex Ratios In An Abundant Colonial Waterbird, Brian S. Dorr, Katie C. Hanson-Dorr, Travis L. Devault, Alban Guillaumet, Scott C. Barras

Brian S Dorr

Demographic information, such as geographic segregation of sexes and sex ratio data, is needed to develop, model and evaluate conservation and management strategies for wildlife. A variety of physiological, behavioral and environmental factors can influence segregation of sexes and sex ratios, many of which originate with density- dependent processes. Departure from 50:50 sex ratios of double-crested cormorants (Phalacrocorax auritus) collected during control efforts in breeding and wintering areas across their eastern range of the USA were evaluated using using a Z-test as well as Stouffer’s weighted Z-tests. In addition, a specifically-designed randomization test was used to evaluate density-dependent ...

Birds are the most species-rich class of tetrapod vertebrates and have wide relevance across many research fields. We explored bird macroevolution using full genomes from 48 avian species representing all major extant clades. The avian genome is principally characterized by its constrained size, which predominantly arose because of lineage-specific erosion of repetitive elements, large segmental deletions, and gene loss. Avian genomes furthermore show a remarkably high degree of evolutionary stasis at the levels of nucleotide sequence, gene synteny, and chromosomal structure. Despite this pattern of conservation, we detected many non-neutral evolutionary changes in protein-coding genes and noncoding regions. These analyses ...
