From Progesterone In Biopsies To Estimates Of Pregnancy Rates: Large Scale Reproductive Patterns Of Two Sympatric Species Of Common Dolphin, Delphinus Spp. Off California, Usa And Baja, Mexico, Nicholas Marc Kellar, Marisa L. Trego, Susan J. Chivers, Fredrick I. Archer, Wayne L. Perryman
Bulletin of the Southern California Academy of Sciences
Blubber progesterone levels were measured in biopsy samples and used to predict the pregnancy status of 507 female common dolphins (204 long-beaked common dolphins, Delphinus capensis, and 303 short-beaked common dolphins, D. delphis). Samples were collected in the coastal waters of the eastern North Pacific between central California, USA and the southern end of Baja California, Mexico. The percentage of females pregnant was similar between the two species: 22.1% (n = 45) of D. capensis and 28.1% (n = 85) of D. delphis. For both species we found strong geographic patterns in pregnancy, suggesting that some areas were more conducive ...
Population Of Northern Leopard Frogs (Rana Pipiens) Migrating Between The Ney Frog Pond And The Minnesota River Valley For Spring Breeding, 2014 Minnesota State University, Mankato
Population Of Northern Leopard Frogs (Rana Pipiens) Migrating Between The Ney Frog Pond And The Minnesota River Valley For Spring Breeding, Rebecca Madison Pollack
Journal of Undergraduate Research at Minnesota State University, Mankato
The Northern Leopard Frogs (Rana pipiens) found at the Ney Nature Center (NNC) are particularly important to the NNC, as they are the initial population of frogs found deformed in 1995. As bio-indicators, frog populations can be used to assess the health of their surrounding environment. This study used standard herpetological field methods to gain a population estimate of Northern Leopard Frogs and the migration route used by these frogs as they moved up the bluffs of the Minnesota River Valley from their wintering site to the Ney Frog Pond for spring breeding. The results gathered provide the Ney Environmental ...
Habitat Preferences Of The Common Nighthawk (Chordeiles Minor) In Cities And Villages In Southeastern Wisconsin, 2014 University of Wisconsin Milwaukee
Habitat Preferences Of The Common Nighthawk (Chordeiles Minor) In Cities And Villages In Southeastern Wisconsin, Jana M. Viel
Theses and Dissertations
Limited survey data and numerous anecdotal accounts indicate that the Common Nighthawk (Chordeiles minor) is experiencing population declines in Wisconsin. However, the magnitude of the decline is unclear because current avian monitoring efforts are not conducted at dusk when Common Nighthawks are most active nor do they specifically target urban areas such as cities and villages where Common Nighthawks are known to nest on flat graveled rooftops. New urban, crepuscular monitoring methods are needed in order to gain a better understanding of current Common Nighthawk demographics in Wisconsin.
The goal of this thesis was to conduct a baseline study using ...

New Species Of Ctenomys Blainville 1826 (Rodentia: Ctenomyidae) From The Lowlands And Central Valleys Of Bolivia, 2014 University of Nebraska - Lincoln
New Species Of Ctenomys Blainville 1826 (Rodentia: Ctenomyidae) From The Lowlands And Central Valleys Of Bolivia, Scott Lyell Gardner, Jorge Salazar-Bravo, Joseph A. Cook
Faculty Publications from the Harold W. Manter Laboratory of Parasitology
The genus Ctenomys Blainville 1826 is one of the most diverse of South American hystricognath rodents. Currently, nine species of tuco-tucos are reported from Bolivia, four at elevations above 2,000 m and five inhabiting the lowlands (< 1,000 m). In the present paper, morphology, karyology, and phylogenetic analyses of DNA sequences for a mitochondrial locus were used to assess the taxonomic status of specimens of Ctenomys from localities beyond the previously known ranges of these rodents in the departments of Chuquisaca, Cochabamba, Santa Cruz, and Tarija. Based on these analyses, we describe four new species in the genus Ctenomys, all apparently endemic to the country. In addition, we place Ctenomys goodfellowi Thomas 1921 in synonymy under C. boliviensis Waterhouse 1848 and confirm the presence of C. nattereri Wagner ...
Prioritizing Non-Marine Invertebrate Taxa For Red Listing, 2014 Northern Michigan University
Prioritizing Non-Marine Invertebrate Taxa For Red Listing, Neil Cumberlidge, Justin Gerlach Phd
The IUCN Red List of threatened species is biased towards vertebrate animals, a major limitation on its utility for overall biodiversity assessment. There is a need to increase the representation of invertebrates (currently 21 % of species assessed on the List;\1 % of all invertebrates). A prioritisation system of terrestrial and freshwater groups is presented here, categorising taxa by species richness, assessment practicality, value for human land use and bioindication, and potential to act as conservation flagships. 25 major taxonomic groupings were identified as priorities, including the Annelida, Arthropoda, Mollusca and Onycophora. Of these, the high-level taxa that emerge as highest ...

Aquaculture, Fish, and Fisheries
Although a number of fish species have been studied in their freshwater life stages, further research on the behavior and habitat requirements of ocean-going fish is required. While fishes have historically been regarded as more “primitive” than other vertebrate groups, Rodriguez et al concluded that several memory and learning systems of bony fishes are noticeably similar to those of reptiles, birds, and mammals. When animals as small and under appreciated as fish display complex mating systems, parental care, and demonstrate the ability to traverse significant distances using olfactory and celestial cues, it is clear that previously established definitions of intelligence ...
Phenotypic Variation In The Model Organism, Danio Rerio, 2014 Portland State University
Phenotypic Variation In The Model Organism, Danio Rerio, Rachel D. Champaigne, Kim H. Brown
Student Research Symposium
Model organisms are used to study evolutionary conserved traits. Zebrafish (Danio rerio) are used a model organism because of their highly fecundity, external fertilization, and robust nature, making them highly adaptable to environmental and genetic variation. In an effort to limit data variation that lies outside of topic interest, phenotypic measures of variation must be performed, understood, and taken into consideration for future studies. A common measurement of phenotypic variation in fish is in the maximum (Ucrit) swimming speeds. Inter and intra-strain variation in zebrafish Ucrit swimming speeds will be observed in a swim tunnel. Baseline values will be recorded ...

International Journal of Speleology
The Cova des Pas de Vallgornera is the longest cave of Mallorca (Balearic Islands, Western Mediterranean) and one of the 30 longest caves in the world. The exploration of one of the galleries allowed the discovery of a fossiliferous deposit of vertebrate remains in a remarkable preservation state. The fossil faunal complex found in this gallery is composed of up to 5 mammalian species (Myotragus aff. kopperi, Hypnomys onicensis, Nesiotites aff. ponsi, Rhinolophus aff. mehelyi and Pipistrellus sp.), at least 14 bird species (among them two Mallorcan endemic taxa: Pica mourerae and Athene vallgornerensis), one reptile (Podarcis aff. lilfordi) and ...

Zutrition: Analyzing And Evaluating Diets Fed To Captive Mammals At Capron Park Zoo, Briell M. Dzierga
Senior Honors Projects
Zoos provide both experiential and educational opportunities for the general public to learn about animals found in a variety of habitats around the world. A successful zoo must provide a safe and enjoyable environment for the visitors, in addition to the species living within the enclosures. Animal husbandry and welfare are crucial aspects to which close attention must be paid, and zoos have a responsibility to attempt to approximate the captive species’ natural habitats and life histories. An essential part of maintaining a captive zoo animal’s health and wellbeing is providing the animal with an appropriate diet. In addition ...

Central Florida Butterfly Conservation: The Importance Of Host Plants In Sandhill And Urban Habitats, Erin S. Josephitis
Honors Program Theses
This study analyzes the relationship between butterfly (Lepidoptera) populations and host plants in a natural sandhill (Wekiwa Springs), a butterfly garden (Leu Gardens), and an urban landscape (Central Park). The Traditional Butterfly Monitoring Scheme is the chosen method for data collection on Lepidoptera populations over a span of nine visits from October - December 2013. Paired t-tests and ANOVA with post hoc Scheffé tests indicate significant correlations between the average number of host plants and overall Lepidoptera abundance, richness, and diversity scores. The life history features of Lepidoptera distributions serve as tools for assessing biodiversity in Central Florida’s natural environment ...

Faculty Publications from the Harold W. Manter Laboratory of Parasitology
From 1989 through 1998, a total of 358 grasshopper mice were collected and examined for helminth and protistan parasites from several habitat types on the Sevilleta Long Term Ecological Research (LTER) site in New Mexico, U.S.A. Of these, 205 individuals were identified as Onychomys leucogaster (Wied-Neuwied 1841) and 153 individuals were classified as O. arenicola Mearns 1896. Many individuals of Onychomys were infected with a new species of Hymenolepididae (Hymenolepis robertrauschi), which is herein described, illustrated, and compared with all species of Nearctic Hymenolepis s. str. Hymenolepis robertrauschi was found in 26% of the individuals of O. arenicola ...
Multilocus Coalescent Analyses Reveal The Demographic History And Speciation Patterns Of Mouse Lemur Sister Species, 2014 Grand Valley State University
Multilocus Coalescent Analyses Reveal The Demographic History And Speciation Patterns Of Mouse Lemur Sister Species, Christopher Blair, Kellie L. Heckman, Amy L. Russell, Anne D. Yoder
Amy L. Russell
Background: Debate continues as to whether allopatric speciation or peripatric speciation through a founder effect is the predominant force driving evolution in vertebrates. The mouse lemurs of Madagascar are a system in which evolution has generated a large number of species over a relatively recent time frame. Here, we examine speciation patterns in a pair of sister species of mouse lemur, Microcebus murinus and M. griseorufus. These two species have ranges that are disparately proportioned in size, with M. murinus showing a much more extensive range that marginally overlaps that of M. griseorufus. Given that these two species are sister ...
Genetic Structure Of Little Brown Bats (Myotis Lucifugus) Corresponds With Spread Of White-Nose Syndrome Among Hibernacula, 2014 Grand Valley State University
Genetic Structure Of Little Brown Bats (Myotis Lucifugus) Corresponds With Spread Of White-Nose Syndrome Among Hibernacula, Cassandra M. Miller-Butterworth, Maarten J. Vonhof, Joel Rosenstern, Greg G. Turner, Amy L. Russell
Amy L. Russell
Until recently, the little brown bat (Myotis lucifugus) was one of the most common bat species in North America. However, this species currently faces a significant threat from the emerging fungal disease white-nose syndrome (WNS). The aims of this study were to examine the population genetic structure of M. lucifugus hibernating colonies in Pennsylvania (PA) and West Virginia (WV), and to determine whether that population structure may have influenced the pattern of spread of WNS. Samples were obtained from 198 individuals from both uninfected and recently infected colonies located at the crest of the disease front. Both mitochondrial (636 bp ...

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
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 ...
Environmental Factors Influencing Spring Migration Chronology Of Lesser Scaup (Aythya Affinis), 2014 Western University
Environmental Factors Influencing Spring Migration Chronology Of Lesser Scaup (Aythya Affinis), Taylor A. Finger
University of Western Ontario - Electronic Thesis and Dissertation Repository
Weather likely affects the timing and rate of migration by waterfowl to their breeding grounds. I hypothesized that timing of migration by lesser scaup during spring is affected by annual variation in temperature, precipitation and ice cover. I used satellite telemetry data, waterfowl survey data and corresponding weather data to evaluate competing models that explained variation in timing and rate of migration by lesser scaup. Timing of spring migration occurred earlier and faster when lesser scaup encountered warmer temperatures and greater precipitation, both of which are known to influence thermoregulation and habitat availability for waterfowl. Migration chronology of lesser scaup ...
Can They Dig It? Functional Morphology And Degrees Of Semifossoriality Among Some American Shrews (Mammalia, Soricidae)., Neal Woodman, Sarah A. Gaffney
Small-eared shrews (Mammalia: Soricidae: Cryptotis), exhibit modifications of the forelimb skeleton that have been interpreted as adaptations for semifossoriality. Most species inhabit remote regions, however, and their locomotory and foraging behaviors remain mostly speculative. To better understand the morphological modifications in the absence of direct observations, we quantified variation in these species by measuring 151 individuals representing 18 species and populations of Cryptotis and two species of moles (Talpidae) for comparison. From our measurements, we calculated 22 indices, most of which have been used previously to characterize substrate use among rodents and other taxa. We analyzed the indices using 1 ...
