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), Taylor A. Finger 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 ...


Animals' Capability To Bond And The Implications That Follow, Falyn Goldfarb 2014 Pace University

Animals' Capability To Bond And The Implications That Follow, Falyn Goldfarb

Honors College Theses

This paper explores the ways in which humans have historically viewed animals, with a focus on Descartes theory automata. Further concepts of the problem of different minds, inherent value, empathy, love, friendship, grief, isolation, anthropomorphism, and biochemistry (focusing on oxytocin, cortisol and the prefrontal cortex) are all explored. Numerous literature reviews are used as examples to fight against the argument that animals are merely machines and can therefore be used and abused. Animal social bonds, including parent-child, purely social, and animal-human, are analyzed for their evolutionary and biological purposes in attempt to highlight the relationships that are not obviously valuable ...


Can They Dig It? Functional Morphology And Degrees Of Semifossoriality Among Some American Shrews (Mammalia, Soricidae)., Neal Woodman, Sarah A. Gaffney 2014 SelectedWorks

Can They Dig It? Functional Morphology And Degrees Of Semifossoriality Among Some American Shrews (Mammalia, Soricidae)., Neal Woodman, Sarah A. Gaffney

Neal Woodman

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 ...

Behavioral Response To A Novel “X” Shape Target Stimuli In A Harbor Seal, Johanna F. Sholar, Anna K. Johnson, Keiko Sampson, Chad Comer, Kevin Drees

Animal Industry Report

The objective of this study was to provide an environmental enrichment device (shape target) to determine if it improved the Harbor Seal’s visibility in the underwater viewing windows when housed at the Blank Park Zoo. One male harbor seal (Phoca vitulina) 3-years of age weighing 39 kg was used. Testing occurred Saturday through Tuesday over 6 consecutive weeks between 1300 and 1330 h. Live observations were collected continuously by one observer. Latency, frequency, and duration were measured. All data is presented descriptively. During baseline the Seal had no interest in the window. Upon presenting the “X” target, he approached ...


Inclusion Of Fresh Pork Pancreas In Raw Pork Meat-Based Diets For African Wildcats (Felis Silvestris Tristrami) Does Not Impact Macronutrient Digestibility, Cheryl L. Morris, Kelly Kappen 2014 Iowa State University

Inclusion Of Fresh Pork Pancreas In Raw Pork Meat-Based Diets For African Wildcats (Felis Silvestris Tristrami) Does Not Impact Macronutrient Digestibility, Cheryl L. Morris, Kelly Kappen

Animal Industry Report

Apparent total tract macronutrient digestibility was evaluated in 4 African wildcats (Felis silvestris tristrami) fed beef or pork-based raw meat diets. Diets were formulated to meet nutrient requirements of cats (NRC, 2006). Cats were fed isocaloric amounts of either control (standard beef raw diet) or pork-based raw diets containing 0, 3, or 5% added raw pancreas, in four 14-day periods. Protein digestibility was higher for pork diets compared with beef and inclusion up to 5% fresh pancreas did not increase macronutrient digestibility in healthy animals. Raw pork can be fed to exotic felids as a viable alternative to standard beef-based ...


Landscape Genetics Of The Marbled Salamander (Ambystoma Opacum) At Mammoth Cave National Park, James Kyle Martin 2013 Western Kentucky University

Landscape Genetics Of The Marbled Salamander (Ambystoma Opacum) At Mammoth Cave National Park, James Kyle Martin

Masters Theses & Specialist Projects

Habitat connectivity is important to maintain in order to prevent loss of genetic diversity, reduce inbreeding depression, and decrease extinction risk in threatened or endangered species. Here I present a landscape genetics study on marbled salamanders (Ambystoma opacum) in highly connected forested habitat at Mammoth Cave National Park. This investigation of gene flow among ponds within a mostly continuous landscape provides data that can be compared with patterns observed in more fragmented landscapes. These comparisons can provide a means of investigating the separate effects of structural and functional habitat connectivity on amphibian genetic population structure. Structural connectivity refers to the ...


An Assessment Of Habitat Suitability For Pronghorn Populations Of The Central Valley Region Of California, Virginia Burroughs 2013 California Polytechnic State University

An Assessment Of Habitat Suitability For Pronghorn Populations Of The Central Valley Region Of California, Virginia Burroughs

Master's Theses and Project Reports

Efforts to reintroduce and maintain populations of pronghorn (Antilocapra americana) to the California Central Valley, specifically the Carrizo Plain National Monument (CPNM) and the Mojave Desert (Antelope Valley) portion of Tejon Ranch, have largely been unsuccessful due to dwindling numbers of translocated animals. The objective of this study was to improve upon previous models for the CPNM using aerial survey data and then apply the model to the Tejon Ranch. Aerial survey data collected from 2000-2010 on the CPNM was used to establish “use” and “non-use” areas in the model. Model variables included vegetation type (forest, shrub, grassland, semi-desert scrub ...


Developmental Plasticity Of Muscle Cellularity And Swim Performance Of Juvenile Chinook Salmon In Response To Temperature, Dan Dohyung Lim 2013 Western University

Developmental Plasticity Of Muscle Cellularity And Swim Performance Of Juvenile Chinook Salmon In Response To Temperature, Dan Dohyung Lim

University of Western Ontario - Electronic Thesis and Dissertation Repository

I investigated the influence of incubation temperature on muscle development and swim performance in juvenile Chinook salmon (Oncorhynchus tshawytscha). In 2011 and 2012, embryos were incubated at different combinations of temperature (7, 9, 15 °C), before and after the onset of free swimming. High-intensity fixed velocity swim tests were performed to assess anaerobic capacity of juveniles. In 2012, these tests were done at a standardized body size (~40 mm). The mean (least-squares) logged times to fatigue of the 15 °C-incubated fish was higher (0.623 ± 0.049 SE) than the 7 °C-incubated fish (0.435 ± 0.048 SE) even after ...


The Envenoming Pandemic And The Misguided Views Of Snakes: Developing Sustainable Relationships Between Native Poisonous Snakes Of India And The Citizens Of Maharashtra Through The Use Of The Irula Model., Destiny Villanueva 2013 California Polytechnic State University

The Envenoming Pandemic And The Misguided Views Of Snakes: Developing Sustainable Relationships Between Native Poisonous Snakes Of India And The Citizens Of Maharashtra Through The Use Of The Irula Model., Destiny Villanueva

Animal Science

Due to its vast population and general negative consensus regarding snakes, India is notorious for having more snakebite incidents than any other country. Snakes are simultaneously revered and feared in Indian religion and culture. This stigma is perpetuated through propaganda, family beliefs, and innate fears of snakes.These stigmas are more pronounced within rural areas, such as the region of Mahad within the state of Maharshtra. Envenoming is endemic in these areas, and others like them. The World Health Organization identified envenoming as one of the most neglected tropical diseases of the 21st century (Nature India, 2013). Additionally, both nonvenomous ...

Breeding Bird Communities Associated With Tallgrass Prairies In Southeast Nebraska, Stephen L. Winter, Samuel D. Fuhlendorf, Britt L. Smith

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

We collected data on bird communities associated with tallgrass prairies in two areas of southeast Nebraska that have been identified for focused conservation action: the Sandstone Prairies Biologically Unique Landscape (BUL) and the Southeast Prairies BUL. Our research was conducted in June and July of 2010 and 2011 at 14 privately–owned and state–owned properties located in Gage, Jefferson, Johnson, and Pawnee Counties. We detected a total of 1,108 individuals representing 41 species during 10–minute point counts with 400–m radii. The most commonly encountered species, in descending order of relative abundance (individuals detected per point count ...


Helminth Parasites Of The Raccoon (Procyon Lotor), Virginia Opossum (Didelphis Virginiana), And Striped Skunk (Mephitis Mephitis) From Keith County, Nebraska, Dennis J. Richardson 2013 University of Nebraska - Lincoln

Helminth Parasites Of The Raccoon (Procyon Lotor), Virginia Opossum (Didelphis Virginiana), And Striped Skunk (Mephitis Mephitis) From Keith County, Nebraska, Dennis J. Richardson

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

Nine raccoons (Procyon lotor), 6 Virginia opossums (Didelphis virginiana), and 1 striped skunk (Mephitis mephitis) collected from Keith County, Nebraska were examined for helminth parasites. Raccoons were infected with the nematodes Arthrocephalus lotoris, Baylisascaris procyonis, and Capillaria plica, the trematode Fibricola cratera, and the tapeworm Atriotaenia procyonis. Opossums were infected with 1 nematode, 1 trematode, and 1 cestode species: Physaloptera turgida, Plagiorhchis elegans, and Oochoristica sp., respectively. The single striped skunk was infected with the nematode Physaloptera maxillaris and the cestodes Mesocestoides sp. and Oochoristica sp.

During a global survey of the diversity of vertebrates and their parasites including the Gobi and desert/steppe biomes ranging from south central to western Mongolia, we found metacestodes (larvae) of Echinococcus multilocularis (Leuckart 1863) in the liver of an individual vole (Microtus limnophilus Büchner 1889) collected in grassland habitat at Har Us Lake, southeast of Hovd, Mongolia. Positive identification of E. multilocularis from near Hovd was made via comparative cyst morphology, study of hooks from the rostellum derived from protoscolexes, and DNA sequencing of the COX1 mitochondrial gene extracted from tissue of the cysts frozen in the field. This ...

Social Decision-Making In A Group Living Cichlid Fish, Adam R. Reddon 2013 McMaster University

Social Decision-Making In A Group Living Cichlid Fish, Adam R. Reddon

Open Access Dissertations and Theses

For my doctoral research I examined social decision-making in a cooperatively breeding cichlid fish, Neolamprologus pulcher with a focus on affiliation and aggression. I investigated the role that the nonapeptide hormone, isotocin, plays in modulating social decisions in these contexts. I show that N. pulcher males prefer to join larger groups regardless of the rank at which they will join, whereas females prefer larger groups only when they can join a group in a high rank (Chapter 2). I examined decision-making during resource contests in (Chapter 3) and found that N. pulcher are sensitive to the size of their opponents ...


Distribution Extension Of Escherbothrium Molinae Berman And Brooks, 1994 (Cestoda: Tetraphyllidea: Triloculariidae) In Urotrygon Sp. From The Pacific Coast Of Mexico, Francisco Zaragoza-Tapia, Scott Monks, Griselda Pulido-Flores, Juan Violante-González 2013 University of Nebraska - Lincoln

The first report of the species was from the Gulf of Nicoya and the Guanacaste coast, Costa Rica; this work represents the second report of the species since the original description and extends its distribution north to Acapulco, Guerrero, Mexico.


Developmental Mode In Opisthobranch Molluscs From The Northeast Pacific Ocean: Additional Species From Southern California And Supplemental Data, Jeffrey H. R. Goddard, Brenna Green 2013 Occidental College

Developmental Mode In Opisthobranch Molluscs From The Northeast Pacific Ocean: Additional Species From Southern California And Supplemental Data, Jeffrey H. R. Goddard, Brenna Green

Bulletin of the Southern California Academy of Sciences

We document development type for 33 species of benthic opisthobranch gastropods – 15 for the first time – collected mainly from the Southern California Bight. Fourteen of the newly examined species had planktotrophic development, while the dorid nudibranch Atagema alba had capsular metamorphic development, the first example of direct development in a non-dendrodoridid nudibranch known from the northeast Pacific Ocean. For the remaining 18 species our new data are either consistent with earlier determinations of development type, or confirm previous inferences. The new data also broaden geographic coverage for some species, and for the sacoglossan Stiliger fuscovittatus and the nudibranch Melibe leonina ...


Reported Incidences Of Parasitic Infections In Marine Mammals From 1892 To 1978, John R. Felix 2013 University of Nebraska - Lincoln

Reported Incidences Of Parasitic Infections In Marine Mammals From 1892 To 1978, John R. Felix

Zea E-Books

The role of parasites in the lives and deaths of marine mammals has been scrutinized by biologists for decades, but the scientific literature prior to 1978 has been difficult to acquire and time-consuming to search. Now this new and extensive bibliography gives researchers a convenient resource for reviewing the classical literature on parasites of marine mammals so that historical infection prevalence and geographical distribution can be easily and properly assessed. This book contains detailed information about accepted (or suspected) taxonomic synonyms and geographical information about the host and/or parasite, covering the parasite groups Acanthocephala, Acarina, Anoplura, Cestoda, Nematoda, and ...

Moving Across The Border: Modeling Migratory Bat Populations, Ruscena Wiederholt, Laura López-Hoffman, Jon Cline, Rodrigo A. Medellín, Paul Cryan, Amy L. Russell, Gary Mccracken, Jay Diffendorfer, Darius Semmens

Amy L. Russell

The migration of animals across long distances and between multiple habitats presents a major challenge for conservation. For the migratory Mexican free-tailed bat (Tadarida brasiliensis mexicana), these challenges include identifying and protecting migratory routes and critical roosts in two countries, the United States and Mexico. Knowledge and conservation of bat migratory routes is critical in the face of increasing threats from climate change and wind turbines that might decrease migratory survival. We employ a new modeling approach for bat migration, network modeling, to simulate migratory routes between winter habitat in southern Mexico and summer breeding habitat in northern Mexico and ...
