The Interictal State In Epilepsy And Behavior, Daniel Tice Barkmeier
Wayne State University Dissertations
Epilepsy is one of the most common neurological diseases, affecting up to 1% of the world population. Epilepsy remains poorly understood and there are currently no medications to cure it. Patients with epilepsy have both seizures as well as another type of abnormal activity between seizures, known as interictal spikes. Interictal spikes have thus far been poorly researched, yet growing evidence supports an important role for them in epilepsy. In this project, we first show the high variability between reviewers in marking interictal spikes on intracranial EEG, and then develop and test an automated detection method to solve this problem. …

Interspecific Variation In Palatability Suggests Cospecialization Of Antipredator Defenses In Sea Hares, Kimberly K. Takagi, Nadia N. Ono, William G. Wright
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Prey species often deploy different kinds of antipredator defenses, which can interact with each other in ways that are not yet completely understood. Much research into these interactions has utilized gastropod mollusks, usually focusing (in part) on the protective utility of the gastropod shell. This makes the evolutionary reduction of the shell in the opisthobranch gastropods (marine slugs) particularly interesting. This loss of protective function of the shell is associated with the evolution of alternative defenses. Particularly well studied are chemical defenses, especially those using secondary metabolites derived from food resources. As a first step toward understanding interspecific variation in …

Cargo Of Birds To Arkansas, The Hurricanes In 2008 And The Swept Clean Hypothesis, Douglas A. James, Kimberly G. Smith, Joseph C. Neal, John G. Hehr
Journal of the Arkansas Academy of Science
Three hurricanes in the hurricane season of 2008 brought to Arkansas several unusual marine and other birds from southerly locations. There were 10 species noted, totaling 44 individual birds. Sooty Terns, numbering 15, were the most numerous. Laughing Gulls were next in abundance. In the mix of birds there was only 1 new species for the state, a Least Grebe. The hurricanes brought vastly different cargos of birds, and two hypotheses relating to how hurricanes transport birds are proposed. The findings supported the "swept clean" hypothesis over the "blown through" hypothesis.

Distribution Of The Southeastern Shrew (Sorex Longirostris Longirostris) In Arkansas, G. A. Mikel, Gary A. Heidt, David W. Clark
Journal of the Arkansas Academy of Science
The southeastern shrew (Sorex longirostris longirostris) is considered uncommon and, due to a lack of knowledge, a Species of Greatest Conservation Need in Arkansas. Also, eastern Arkansas may represent a gap in the species’ distribution. Therefore, we evaluated persistence at previous capture sites, surveyed additional counties, quantified microhabitat at our capture locations, and compiled occurrences. Since Sealander and Heidt’s (1990) Arkansas Mammals detailed its occurrence, additional captures by Huston and Nelson (1994), Showen (2006), and this study document new counties (Pope and Searcy) and a new ecoregion (Arkansas Valley). Number of specimens in Arkansas has increased to 17 in 11 …

Population Status Of The Southern Cavefish, Typhlichthys Subterraneus In Arkansas, A. Romero, M. S. Connor, G. L. Vaughan
Journal of the Arkansas Academy of Science
We summarize the results of our study on the status of the southern cavefish (Typhlichthys subterraneus) in Arkansas. Its presence in the state represents the western-southern limits of its distribution. Four localities have been confirmed that contain individuals of this species: Richardson Cave (Fulton County), Alexander Cave/Clark Spring (Stone County), Ennis Cave (Stone County), and Lake Norfork (Baxter County). A fifth locality has been cited as a well in Randolph County, but because the exact location is unknown, its presence has not been confirmed. A number of unconfirmed localities for “cavefishes” in the region has not been included in this …

Status And Distribution Of The Gapped Ringed Crayfish, Orconectes Neglectus Chaenodactylus, In Arkansas, Brian K. Wagner, C. A. Taylor, Mark D. Kottmyer
Journal of the Arkansas Academy of Science
Orconectes neglectus chaenodactylus, the gapped ringed crayfish, is an uncommon and poorly-known, stream-dwelling crayfish that is endemic to the central White River basin of Arkansas and Missouri. This study surveyed a semi-random selection of stream sites in the Arkansas portion of this range in order to characterize the crayfish communities and evaluate the status of O. n. chaenodactylus in Arkansas. Collections of a total of 1,107 individual crayfish specimens were made at 45 sites, including 497 O. n. chaenodactylus from 21 sites. Orconectes punctimanus was the crayfish species most commonly associated with O. n. chaenodactylus, occurring at 71% of sites …

Seasonal Activity Of The Ozark Highlands Leech, Macrobdella Diplotertia, (Annelida: Hirudinea) In North-Central Arkansas, M. Connior, Stanley E. Trauth
Journal of the Arkansas Academy of Science
The Ozark Highlands Leech, Macrobdella diplotertia, occurs intermittently throughout Arkansas, Kansas, and Missouri. Limited natural history of this species is known. Herein, we report a new county occurrence for this leech from a cattle pond in southern Marion County, Arkansas. We also report on the seasonal activity and novel hosts of this species. We surveyed the inhabited pond monthly to determine activity and collected natural history data on this species. This study indicated that this species appears to be most active in spring, summer, and early fall, but inactive during the winter. We also documented five new anuran hosts for …

A comprehensive understanding of migration dynamics, within-estuary behaviors and physiological tolerances of fish is needed to assess and predict future responses of fish to environmental disturbance and to protect habitat necessary for growth and survival. This study adds to current knowledge of summer flounder (Paralichthys dentatus) responses to environmental conditions by (1) examining migration and within-estuarine behaviors of adult summer flounder and (2) establishing summer flounder metabolic requirements and cardiorespiratory responses to variations in hypoxia and temperature. To elucidate use of a southern mid-Atlantic Bight estuary by adult summer flounder, the movements of 45 fish were monitored using acoustic telemetry …

Ectoparasites Of Bats In Mongolia (Ischnopsyllidae, Nycteribiidae, Cimicidae And Spinturnicidae), Ingo Sceffler, Dietrich Dolch, Jargalsaikhan Ariunbold, Nyamsuren Batsajchan, Andreas Abraham, Klaus Thiele
Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298
For large parts of the world, the knowledge of bat ectoparasites is still scanty. Regarding Mongolia, only few studies exist to date. This paper analyzes results from extensive captures between 2005-2008, carried out in different sites of Mongolia. Discussed ectoparasites include bat fleas, (Ischnopsyllidae), bat flies (Nycteribiidae), and bat bugs (Cimicidae) and spinturnicid mites (Spinturnicidae). A number of species found in this study were new records for Mongolia, and for many species additional sites were reported. For some bat species, the spectrum and frequency of larger ectoparasites could be determined for the first time.

Zoo Registrars: A Bewildering Bureaucracy, Irus Braverman
Journal Articles
While their counterparts in the museum world have received some scholarly attention, no scholarly account of zoo registrars has been published to date. Why bother studying zoo registrars? Firstly, in the (contained) wildness of the zoo, the registrar performs the role of law and order. She (typically this position is employed by females) manages the administrative side of the zoo: a junction between data management and small-scale legal administration. Secondly, registrars both depict and represent the significant transformations that have occurred in North American zoos over the last few decades, from insular urban institutions exhibiting exotic animals for entertainment, to …

Lobster Attack Induces Sensitization In The Sea Hare, Aplysia Californica, Amanda J. Watkins, Daniel A. Goldstein, Lucy C. Lee, Christina J. Pepino, Scott L. Tillett, Francis E. Ross, Elizabeth M. Wilder, Virginia A. Zachary, William G. Wright
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
Studies of the neural mechanisms of learning, especially of sensitization, have benefitted from extensive research on the model species, Aplysia californica (hereafter Aplysia). Considering this volume of literature on mechanisms, it is surprising that our understanding of the ecological context of sensitization in Aplysia is completely lacking. Indeed, the widespread use of strong electric shock to induce sensitization (an enhancement of withdrawal reflexes following noxious stimulation) is completely unnatural and leaves unanswered the question of whether this simple form of learning has any ecological relevance. We hypothesized that sublethal attack by a co-occurring predator, the spiny lobster, Panulirus interruptus, might …

Notes On Some Egyptian Lacertidae, Including A New Subspecies Of Mesalina, Involving The Seligmann Effect, Yehudah Leopold Werner, Shoshana Ashkenazi
Turkish Journal of Zoology
These notes on some Egyptian lacertid lizards contribute to faunal data for the planning of biodiversity conservation. Mesalina bahaeldini curatorum n. subsp. is described from Suez, characterized by coloration and larger (fewer) body scales. Range extensions are documented for Acanthodactylus aegyptius, Mesalina olivieri, and M. rubropunctata. The previously reported occurrence of A. opheodurus in Sinai is doubted. The fact that the M. b. curatorum types were collected in the 1820s demonstrates the importance of museum collections.
