Stopover Ecology Of Ruby-Throated Hummingbirds (Archilochus Colubris) During Autumn Migration, Theodore Joseph Zenzal Jr 2016 University of Southern Mississippi

Stopover Ecology Of Ruby-Throated Hummingbirds (Archilochus Colubris) During Autumn Migration, Theodore Joseph Zenzal Jr

Dissertations

The Ruby-throated Hummingbird (Archilochus colubris) is one of the smallest Nearctic-Neotropical migrants and the only species of hummingbird that breeds in Eastern North America, yet few studies have investigated the biology of Ruby-throated Hummingbirds when they stopover during migration. Given their small size, high metabolism, aggression, and specialized diet, hummingbirds may represent a migrant that operates on the physiological edge. Therefore it is important to understand the factors that influence their stopover as well as the decision to resume migration. Towards this end, Ruby-throated Hummingbirds were captured during autumn migration along the northern coast of the Gulf of Mexico to ...


Nudibranch Range Shifts Associated With The 2014 Warm Anomaly In The Northeast Pacific, Jeffrey HR Goddard, Nancy Treneman, William E. Pence, Douglas E. Mason, Phillip M. Dobry, Brenna Green, Craig Hoover 2016 University of California, Santa Barbara

Nudibranch Range Shifts Associated With The 2014 Warm Anomaly In The Northeast Pacific, Jeffrey Hr Goddard, Nancy Treneman, William E. Pence, Douglas E. Mason, Phillip M. Dobry, Brenna Green, Craig Hoover

Bulletin of the Southern California Academy of Sciences

Abstract.—The Northeast Pacific Ocean was anomalously warm in 2014, despite ENSO-neutral conditions in the tropical Pacific. We documented northern range shifts associated with this anomaly for 30 species of nudibranchs and other shallow-water, benthic heterobranch gastropods from southern California to southern Oregon. Nine of these (Placida cremoniana, Trapania velox, Doriopsilla fulva, Janolus anulatus, J. barbarensis, Flabellina cooperi, Anteaeolidiella chromosoma, A. oliviae, and Noumeaella rubrofasciata) were recorded from new northernmost localities, while the remainder were found at or near northern range limits established mainly during past El Niño events. All 30 species have planktotrophic larval development, and six were observed ...

Natural Skeletal Pathologies In A Population Of Gray Squirrels, Sciurus Carolinensis, From Putnam County, Georgia, Anna M. Bosch, Katelyn J. Benson, Alfred J. Mead 2016 Georgia College and State University

Natural Skeletal Pathologies In A Population Of Gray Squirrels, Sciurus Carolinensis, From Putnam County, Georgia, Anna M. Bosch, Katelyn J. Benson, Alfred J. Mead

Georgia Journal of Science

Antemortem bone remodeling following severe trauma leads to bone disfigurement that serves as a skeletal record of the injury resulting from events such as nonfatal predator attacks, aggressive intraspecific interactions, or accidental injuries related to lifestyle hazards. In the current study, pathologic bone regrowth was analyzed in a sample of 91 eastern gray squirrel (Sciurus carolinensis) skeletons from Putnam County, Georgia. The occurrence, frequency, and position of bridging fracture calluses, bone misalignments, bone-surface perforations, and localized superficial calluses were recorded and compared to other terrestrial, semiarboreal, and arboreal mammalian species. Evidence of healed bone fractures was observed in 41% of ...


The First Record Of Malformed Pectines In Genus Euscorpius (Scorpiones: Euscorpiidae), Miroslav Šarić, Jovana Tomić 2016 University of Novi Sad

The First Record Of Malformed Pectines In Genus Euscorpius (Scorpiones: Euscorpiidae), Miroslav Šarić, Jovana Tomić

Euscorpius

A teratological change in a pectinal organ of Euscorpius cf. carpathicus (C. L. Koch, 1837) from Serbia had been examined using SEM (Scanning Electron Microscopy), and compared to specimens with normally developed pectines. Possible reasons for this anomaly are discussed.


Microstructures Produced By Hadrosaur Bones From Alaska And Wyoming, Mark P. Guilliams, Samantha J. Lefaive, Michael D. Sprague 2016 Cedarville University

Microstructures Produced By Hadrosaur Bones From Alaska And Wyoming, Mark P. Guilliams, Samantha J. Lefaive, Michael D. Sprague

The Research and Scholarship Symposium

Since 2005 when Dr. Mary Schweitzer made the first discovery, microstructures with the appearance of “osteocytes” and “blood vessels” have been recovered from fossils of various localities, dating back as far as the Triassic. The majority of these finds have come from dense, cortical bone but recently have been discovered in cancellous bone. Since her initial discovery, Schweitzer has done a lot of work to verify that these microstructures are not biofilms, but instead are original organic tissue. This project was looking to get similar results to Schweitzer’s research and to find a simple test method for the initial ...


Effects Of Nutrition On Female Leopard Geckos, Lisa Keys, Dennis M. Ferraro 2016 university of nebraska-lincoln

Effects Of Nutrition On Female Leopard Geckos, Lisa Keys, Dennis M. Ferraro

UCARE Research Products

Nutrition has a dramatic effect on animal’s bodies and behaviors as they go through their lives. Looking at the effects of nutrition on captive animals is crucial to providing future animals with better lives. Since captive animals don’t get the variety of food items that they would get in the wild, supplementation is often used to meet the minimum dietary requirements. Looking at how supplementation affects female leopard geckos at breeding size, there were both positive and negative correlations with different supplementations used. After taking body measurements on females over several months on one kind of additional supplement ...


Global Phylogeny Of The Water Penny Beetles Using Both Molecular And Morphological Evidence (Co, Mathew Vincent Wood 2016 Western Kentucky University

Global Phylogeny Of The Water Penny Beetles Using Both Molecular And Morphological Evidence (Co, Mathew Vincent Wood

Masters Theses & Specialist Projects

The Psephenidae is a family of freshwater beetles usually found in swift streams worldwide. Their unique disc shaped and flattened larvae have made this a group of interest for scientists for centuries. Morphologically, this family has been relatively well researched, and systematically the family is fairly well known and supported as monophyletic. One issue with Psephenidae, and with many other insect groups, is the lack of the molecular phylogenetic analyses to test morphology hypothesizes.

After successfully sequencing these two genes from species representing nearly all of the known genera, the data were analyzed using both Bayesian and parsimony methods. Analyses ...


The Line Drawn On Pain Still Holds, Bjorn H. Merker 2016 retired, no institutional affiliation

The Line Drawn On Pain Still Holds, Bjorn H. Merker

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

The many substantive criticisms raised against Key by me and by many of the other commentators will not disappear by ignoring or waving them aside with meta-discourse about anthropomorphism, just-so stories, or celestial teapots. The conceptual edifice Key inhabits and defends with such gusto may look like an impregnable fortress from the inside – and Key behaves as if it were. From the outside, however, it looks more like a ramshackle structure gaping with holes and pieced together from imperfectly understood neuroscience and often faulty literature citations.


Slavery, Welfare And The Sixth Extinction, Stephen R. Clark 2016 University of Liverpool

Slavery, Welfare And The Sixth Extinction, Stephen R. Clark

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Ng’s laudable concern for animal welfare would be welcome to any sensible slave-owner wishing to preserve his investment. What welfarism – for slave-owners and animal husbandmen – fails to call into question is whether we have the right to breed, hold captive and kill animals at all: If it matters, as the widely recognized slogan of ‘Five Freedoms’ suggests, that animals have the chance to live a ‘normal’ life, then more matters than keeping them ‘happy’ in subjection. Their lives – and also the lives of wild things – also deserve respect.

Interactions Of A Captive Maturing Female Hamadryas Baboon, Jordyn Kessler, Janice L. Chism Ph.D. 2016 Winthrop University

Interactions Of A Captive Maturing Female Hamadryas Baboon, Jordyn Kessler, Janice L. Chism Ph.D.

The Winthrop McNair Research Bulletin

In the wild, hamadryas baboons (Papio hamadryas hamadryas) typically practice male philopatry, where females transfer out of natal units to avoid inbreeding (Swedell et al. 2011). However, little is known about hamadryas female transfer in captivity. In this study, we used focal animal sampling (Altmann 1974) to observe female transfer in a captive group comprised of two one-male units. The group includes a subadult female, whom we expected to transfer to the non-natal unit soon after reaching sexual maturity. We recorded the proximity between the subadult female and all other individuals, as well as affiliative and agonistic behavior exhibited between ...


Wild Animal Suffering And Vegan Outreach, Eze Paez 2016 Pompeu Fabra University

Wild Animal Suffering And Vegan Outreach, Eze Paez

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Ng’s strategic proposal seems to downplay the potential benefits of advocacy for wild animals and omit what may be the most effective strategy to reduce the harms farmed animals suffer: vegan outreach.


Declining Frequency Of Road-Killed Rabbits In Central Georgia, Anna M. Bosch, Katelyn J. Benson, Alfred J. Mead 2016 Georgia College and State Univeristy

Declining Frequency Of Road-Killed Rabbits In Central Georgia, Anna M. Bosch, Katelyn J. Benson, Alfred J. Mead

Georgia Journal of Science

Cottontail rabbits (Sylvilagus floridanus, Sylvilagus aquaticus, Sylvilagus palustris) are a common component of the mammal fauna of the southeastern United States, yet their numbers have been in decline for at least the past 40 years. Urban sprawl, land use changes, forest maturation, and increased predation have contributed to the decline in Georgia. In the current study we explore the proposition that long-term changes in roadkill frequency track changes in wildlife populations as a whole. Using comparisons of historical data collected by Georgia Department of Natural Resources personnel and recent roadkill census data from Baldwin County, it appears that the overall ...

New Data On The Distribution Of Butheoloides Littoralis Lourenço, Touloun Et Boumezzough, 2011 (Scorpiones: Buthidae) Oulaid, Oulaid Touloun, Moulay Abdelmonaim El Hidan, Ali Boumezzough

Euscorpius

Morocco is the region in Africa with the highest diversity of Butheoloides Hirst, 1925 species. Until now, the total number of species of this genus known from Morocco is raised to five. A field study conducted in southern Morocco discovered a new specimen of Butheloides littoralis in the Tighmi region (southeast of Tiznit), the most continental site of this species in Morocco. This specimen is the third of this endemic species of Morocco but it is the first male discovered.


Animal Suffering And Human Bias, Stijn Bruers 2016 Ghent University

Animal Suffering And Human Bias, Stijn Bruers

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Ng proposes concrete ways to decrease animal suffering on the basis of commonsense economic logic and research in welfare biology. But to reduce animal suffering effectively in livestock farming, animal experimentation or the natural environment we have to become more aware of our pervasive and spontaneous but unreliable intuitive moral judgments. These can generate biases that prevent us from decreasing animal suffering effectively.


An Animal Victim's Best Chance: Veterinary Legal Duty To Report Cruelty In The U.S., Lora Dunn 2016 Animal Legal Defense Fund

An Animal Victim's Best Chance: Veterinary Legal Duty To Report Cruelty In The U.S., Lora Dunn

Animal Sentience: An Interdisciplinary Journal on Animal Feeling

Legislation throughout the U.S. recognizes animal sentience and the importance of veterinary reporting to combat the ongoing suffering of these animal victims: All 50 states have felony penalties available for animal cruelty crimes, and veterinary reporting is permitted or required in the majority of states. The remaining minority of U.S. states should take action to require veterinarians to report animal cruelty and render veterinarians immune for good faith reporting.
