Seasonal Habitat Selection Of The North American Porcupine (Erethizon Dorsatum) In A Coastal Dune Forest, Cara L. Appel 2016 Humboldt State University

Seasonal Habitat Selection Of The North American Porcupine (Erethizon Dorsatum) In A Coastal Dune Forest, Cara L. Appel

Cal Poly Humboldt theses and projects

Wildlife-habitat relationship studies are important for understanding the factors that determine where species occur in space and time. Habitat selection by generalist species should be studied on fine spatial and temporal scales to avoid masking important differences between seasons, localities, or orders of selection. I conducted the first study of habitat use and general ecology of North American porcupines (Erethizon dorsatum) in a coastal dune environment. Specifically, I assessed changes in body mass, home range size, and habitat selection in relation to the potential for seasonal nutritional and survival bottlenecks as reported elsewhere. Although they are considered generalists, …


Genetic Structure And Connectivity Of The Endangered Giant Kangaroo Rat (Dipodomys Ingens) In A Heterogeneous Environment, Nathan Alexander 2016 Humboldt State University

Genetic Structure And Connectivity Of The Endangered Giant Kangaroo Rat (Dipodomys Ingens) In A Heterogeneous Environment, Nathan Alexander

Cal Poly Humboldt theses and projects

Movement ecology and dispersal are important aspects of species’ life histories that can inform conservation and management. Dispersal is often cryptic and difficult to detect, but recent advances genetic technology and applications have provided new approaches to identifying and describing dispersal patterns. Giant kangaroo rats (Dipodomys ingens) are an endangered heteromyid that appear to persist in small subpopulations in a heterogeneous environment of their northern range, the Ciervo-Panoche Natural Area, California. Previous work suggested high levels of genetic diversity between populations with genetic distances not being correlated to geographic distances. Here, I identified landscape population structure through clustering …


Testing The Forage Preference Of The American Pika (Ochotona Princeps) For Use In Connectivity Corridors In The Washington Cascades, Carly Wickhem, Kristina Ernest 2016 Central Washington University

Testing The Forage Preference Of The American Pika (Ochotona Princeps) For Use In Connectivity Corridors In The Washington Cascades, Carly Wickhem, Kristina Ernest

All Master's Theses

One of the aims of the Snoqualmie Pass East Project (SPEP) in the Cascades of central Washington is to construct nearly 30 wildlife crossing structures along a 15-mile stretch of Interstate-90. American pikas (Ochotona princeps) are being monitored for the SPEP because they have specific habitat requirements and are poor dispersers. Making the crossing structures “pika-friendly” will encourage these low-mobility animals to use the structures. Recent research suggests that the presence of quality vegetation may help pika populations avoid declines and extirpations, so planting suitable forage within and adjacent to the crossings will be essential. During the summer …


Animal Suffering Calls For More Than A Bigger Cage, Simon R. B. Leadbeater 2016 Independent researcher

Animal Suffering Calls For More Than A Bigger Cage, Simon R. B. Leadbeater

Animal Sentience

Ng (2016) argues for incremental welfare biology partly because it would be impossible to demonstrate conclusively that animals are sentient. He argues that low cost changes in industrial practices and working collaboratively may be more effective in advancing animal welfare than more adversarial approaches. There is merit in some of Ng’s recommendations but a number of his arguments are, in my view, misdirected. The fact that nonhuman animals feel has already been adequately demonstrated. Cruelty to animals is intrinsic to some industries, so the only way to oppose it is to oppose the industry.


Ecology Of Two Reintroduced Black Bear Populations In The Central Appalachians, Sean McCarthy Murphy 2016 University of Kentucky

Ecology Of Two Reintroduced Black Bear Populations In The Central Appalachians, Sean Mccarthy Murphy

Theses and Dissertations--Animal and Food Sciences

Reintroduced populations are vulnerable to demographic and environmental stochasticity, deleterious genetic effects, and reduced population fitness, all of which can increase extinction probability. Population viability is principle to determining the status of reintroduced populations and for guiding management decisions. To attempt to reestablish black bear (Ursus americanus) populations in the central Appalachians, two reintroductions using small founder groups occurred during the 1990s in the Big South Fork area along the Kentucky-Tennessee border (BSF) and in the Jefferson National Forest along the Kentucky-Virginia border (KVP). My objectives were to estimate demographic and genetic parameters, and to evaluate long-term viability …


The Small Mammals Of Southeastern Virginia As Revealed By Pitfall Trapping, Robert K. Rose 2016 Old Dominion University

The Small Mammals Of Southeastern Virginia As Revealed By Pitfall Trapping, Robert K. Rose

Biological Sciences Faculty Publications

Pitfall trapping is a poor method to catch small mammals but the only way to catch and study the Southeastern Shrew (Sorex longirostris), the primary mammal of interest in the field studies reported here. While learning much about its distribution and abundance, still more was learned about the other small mammals present in forests and fields of eastern Virginia. A total of 15 species was captured at 19 locations during the 1990-2013 period, including five shrews, two moles, and eight rodents, representing all but one of the common small mammals in eastern Virginia.


Mediterranean Water Shrew (Neomys Anomalus): Range Expansion Northward, LINAS BALCIAUSKAS, LAIMA BALCIAUSKIENE, UUDO TIMM 2016 TÜBİTAK

Mediterranean Water Shrew (Neomys Anomalus): Range Expansion Northward, Linas Balciauskas, Laima Balciauskiene, Uudo Timm

Turkish Journal of Zoology

We identified three individuals of the Mediterranean water shrew (Neomys anomalus) in Estonia, expanding the known distribution range of the species to the north by 500 km from the most northern location in Lithuania and over 700 km from Poland. The identification of the species in Estonia, the most northern known locality, was based on the position of mental foramen, height of coronoid process (>4.3 mm), and Libois index (

A newly recorded species for the Turkish fauna, Camerotrombidium rasum Berlese, 1910, is given based on adult females and larvae obtained from an adult female by experimental rearing in the laboratory. The genus Camerotrombidium is recorded for the first time from Turkey.


A New Locality Record For Phoenicolacerta Laevis (Gray, 1838)(Squamata: Lacertidae) In Western Anatolia, ÇETİN ILGAZ, YUSUF KUMLUTAŞ, KAMİL CANDAN 2016 TÜBİTAK

A New Locality Record For Phoenicolacerta Laevis (Gray, 1838)(Squamata: Lacertidae) In Western Anatolia, Çeti̇n Ilgaz, Yusuf Kumlutaş, Kami̇l Candan

Turkish Journal of Zoology

During fieldwork in western Anatolia 4 specimens (1 adult male, 2 subadult males, and 1 subadult female) of Phoenicolacerta laevis from Dalaman, Muğla Province, were collected in November 2014. The results including meristic pholidolial characteristics, metric measurements, and color-pattern features of specimens are compared with the data given in the previous literature. The occurrence of P. Laevis in southern and western Anatolia is discussed.


An Update Note On Diversity And Conservation Of The Endemic Fishes In Iranian Inland Waters, AZAD TEIMORI, HOSSEIN MOSTAFAVI, HAMID REZA ESMAEILI 2016 TÜBİTAK

An Update Note On Diversity And Conservation Of The Endemic Fishes In Iranian Inland Waters, Azad Teimori, Hossein Mostafavi, Hamid Reza Esmaeili

Turkish Journal of Zoology

The diversity, distribution pattern, and conservation status of endemic species were obtained by analysis of catalogued specimens collected by fieldwork carried out by the authors at various times in different regions in Iran since 2002. The Iranian endemic ichthyofauna includes 51 species and forms a significant part of the total species known from this country, so that new endemic species are being described almost every year. The highest endemicity is found in the Tigris-Karoun basin in the west, followed by the Kor River and the Persian Gulf basins in the south. Creation of the landlocked basins played an important role …


Anticipatory Grief, Tara Fox Hall 2016 Independent Scholar

Anticipatory Grief, Tara Fox Hall

Animal Sentience

This commentary reviews Barbara King’s How Animals Grieve, delving into the controversial topic of the status of animals in our society, as well as the key difference between human and non-human grief: the ability to anticipate death.



Modulation Of Behavior In Communicating Emotion, Martin Gardiner 2016 Brown University

Modulation Of Behavior In Communicating Emotion, Martin Gardiner

Animal Sentience

King discusses many examples where two animals, as they bond, behave in ways we interpret as expressing love for one another. If one of the bonded animals then dies, signs of loving are replaced by signs we interpret as expressing grief by the animal who remains. I propose a pathway for emotional communication between an animal and an observer that can have a central role in these and other observations by King and in our overall ability to interpret observed behavior in relation to emotion. This pathway provides evidence of emotion in an observed animal by communicating evidence of emotion’s …


Sentience And Animal Welfare: Affirming The Science And Addressing The Skepticism, Nancy Clarke 2016 World Animal Protection

Sentience And Animal Welfare: Affirming The Science And Addressing The Skepticism, Nancy Clarke

Animal Sentience

Broom’s (2014) book is a well-researched and thoroughly written exploration and evaluation of the journey from the origins of animal welfare science to what we can say we now know and need to consider in relation to animal sentience and welfare. This book will help to counter any skepticism among academics and policy makers.


Nonhuman Mind-Reading Ability, Marthe Kiley-Worthington 2016 Centre d’Eco-Etho Recherche et Education

Nonhuman Mind-Reading Ability, Marthe Kiley-Worthington

Animal Sentience

Harnad (2016) is mistaken that humans are better at mind-reading than other species. Humans have context-independent language, but nonhuman species, especially mammals, have context-dependent nonverbal skills – perceptual, communicative and social -- that can be much keener than our own.


Cognitive Evidence Of Fish Sentience, Jonathan Balcombe 2016 Humane Society Institute for Science and Policy

Cognitive Evidence Of Fish Sentience, Jonathan Balcombe

Animal Sentience

I present a little-known example of flexible, opportunistic behavior by a species of fish to undermine Key’s (2016) thesis that fish are unconscious and unable to feel. Lack of a cortex is flimsy grounds for denying pain to fish, for on that criterion we must also then deny it to all non-mammals, including birds, which goes against scientific consensus. Notwithstanding science’s fundamental inability to prove anything, the precautionary principal dictates that we should give the benefit of the doubt to fish, and the state of the oceans dictates that we act on it now.


Mediating Claims Through Critical Anthropomorphism, Gordon Burghardt 2016 University of Tennessee, Knoxville

Mediating Claims Through Critical Anthropomorphism, Gordon Burghardt

Animal Sentience

Key’s (2016) discussion of his claim that fish do not feel pain ignores the history of attempts to study the attribution of mental states to other species. Although willing to accept that mammals feel pain, Key claims that fish lack the mammalian neural mechanisms underlying pain and are unconscious of their experiences. Consequently, we do not need to be overly concerned about fishing practices that would otherwise be viewed as painful. Key uses a flawed anthropomorphic lens. All attributions of mental events to organisms other than oneself involve inferences derived from anthropomorphic processes through which we process physiological and behavioral …


Population Genetic Structure Of Necturus Maculosus In Central And Eastern Kentucky, Mason Owen Murphy 2016 University of Kentucky

Population Genetic Structure Of Necturus Maculosus In Central And Eastern Kentucky, Mason Owen Murphy

Theses and Dissertations--Biology

Population structure is influenced by extrinsic factors, such as landscape architecture and dispersal barriers. Lotic network architecture is known to constrain ecological, demographic and evolutionary processes, including population genetic structure. I assessed the population structure of a widespread aquatic salamander, Necturus maculosus, across three river basins in central and eastern Kentucky. I examined the role of network architecture, anthropogenic barriers, and spatial scale on patterns of population structure. I also provided a review of N. maculosus capture methods and offer an improved trap design. I identified significant structuring between the combined Licking/Kinniconick basin and the Kentucky River basin, with …

New Verified Nonindigenous Amphibians And Reptiles In Florida Through 2015, With A Summary Of More Than 152 Years Of Introductions, Kenneth L. Krysko, Louis A. Somma, Dustin C. Smith, Christopher R. Gillette, Daniel Cueva, Joseph A. Wasilewski, Kevin M. Enge, Steve A. Johnson, Todd S. Campbell, Jake R. Edwards, Michael R. Rochford, Ryan Tompkins, Jeffrey L. Fobb, Scott Mullin, Christopher J. Lechowicz, Dallas Hazelton, Alície Warren

Papers in Herpetology

More nonindigenous species occur in Florida, USA, than any other region worldwide and may threaten many of Florida’s natural resources. The frequency of new reports mandates the need for regular updates. Herein, we use photographic and specimen vouchers in addition to literature records to provide updated information on verified nonindigenous amphibians and reptiles in Florida. Between our most recent summary in 2012 and the end of 2015, 38 additional species are known to have been intercepted (n = 2) or introduced (n = 36). We also update the invasion stage of seven species previously reported from Florida and …
