Pyroghatsiana: A New Genus Of Fire-Colored Beetles (Coleoptera: Pyrochroidae: Pyrochroinae) From The Southern Ghats, India, Daniel K. Young
Insecta Mundi
Pyroghatsiana, a new genus of pyrochroine Pyrochroidae is described from the Southern Ghats of the Indian continental southern tip. The only known specimen is a female, Pyroghatsiana madurensis (Pic), new combination, originally placed in Dendroides Latreille, and subsequently transferred to Pseudodendroides Blair. Several striking differences including the dorsal interocular width between the compound eyes, shape and length of the third antennal segment, and shape of the pronotum preclude placement of Pyroghatsiana in either Dendroides, Pseudodendroides, or any other existing pyrochroine genus.

Absence Of Mate Choice And Postcopulatory Benefits In A Species With Extreme Sexual Size Dimorphism, Marie-Claire Chelini, Eileen A. Hebets
Absence Of Mate Choice And Postcopulatory Benefits In A Species With Extreme Sexual Size Dimorphism, Marie-Claire Chelini, Eileen A. Hebets
Eileen Hebets Publications
Most hypotheses related to the evolution of female-biased extreme sexual size dimorphism (SSD) attribute the differences in the size of each sex to selection for reproduction, either through selection for increased female fecundity or selection for male increased mobility and faster development. Very few studies, however, have tested for direct fitness benefits associated with the latter – small male size. Mecaphesa celer is a crab spider with extreme SSD, whose males are less than half the size of females and often weigh 10 times less. Here, we test the hypotheses that larger size in females and smaller size in males …

To Jump Or Not To Jump: Mule Deer (Odocoileus Hemionus) And White-Tailed Deer (Odocoileus Virginianus) Crossing Decisions, Emily N. Burkholder
Undergraduate Theses, Professional Papers, and Capstone Artifacts
There have been recent efforts to enhance ungulate movement through modified fencing structures. Ungulates such as mule deer (Odocoileus hemionus) and white-tailed deer (Odocoileus virginianus) typically negotiate fences by either jumping over fencing or going under. Here we examine crossing success and crossing decisions of mule deer and white-tailed deer and determine factors that influence crossing success and the impending decision to jump over or crawl underneath fencing. Using a BACI (Before-After-Control-Impact) design, we deployed remote cameras along fence lines in three study areas; Canadian Forces Base (CFB) Suffield and OneFour research center in Southeastern Alberta, …

Influence Of Fine Sediment On Arctic Grayling (Thymallus Arcticus) Egg Survival And Spawning Habitat Suitability, Ian R. Anderson
Undergraduate Theses, Professional Papers, and Capstone Artifacts
The Arctic grayling (Thymallus arcticus) is a freshwater salmonid that is found in clear, cold waters throughout the northern regions of North America. Arctic grayling are still widespread in Alaska and Canada but have declined substantially in their two historic, disjunct southern populations in the contiguous United States. One of these populations was found in the AuSable River in Michigan and went extinct in the mid-1900s (Vincent 1962) while the other, found in the Upper Missouri River drainage in Montana, now inhabits a small portion of its historical range (Nelson 1954). Currently, only two native populations of Arctic …
Evidence For Use Of Alliaria Petiolata In North America By The European Cabbage White Butterfly, Pieris Rapae, Sam L. Davis, Don Cipollini
Evidence For Use Of Alliaria Petiolata In North America By The European Cabbage White Butterfly, Pieris Rapae, Sam L. Davis, Don Cipollini
Biological Sciences Faculty Publications
Pieris rapae L., an invasive crop pest, may have recently begun using Alliaria petiolata Bieb. (Cavara & Grande), a European invasive biennial. We investigated how P. rapae uses forest habitats for nectar and oviposition and examined larval performance on A. petiolata in the field and laboratory. Being known primarily to occupy open habitats, we found that P. rapae regularly uses forest edge habitats, most surveyed A. petiolata plants had P. rapae damage, and P. rapae successfully used both stages of A. petiolata for larval development.
Shell Repair In Geukensia Demissa And Predation Preferences Of Callinectes Sapidus: Do Crabs Target Mussels With Weakened Shells?, Madeleine S. Gillis
Shell Repair In Geukensia Demissa And Predation Preferences Of Callinectes Sapidus: Do Crabs Target Mussels With Weakened Shells?, Madeleine S. Gillis
Electronic Theses and Dissertations
Atlantic blue crabs, Callinectes sapidus, are voracious predators that often leave damage on the shells of unconsumed ribbed marsh mussels, Geukensia demissa. The extent of shell damage and size-dependent tradeoffs in marsh mussel growth and repair, as well as the effects of shell damage on crab predation preferences, were determined in this thesis. A preliminary experiment investigated characteristics of damaged mussels in the field. Mussels (n = 30) were collected in the fall of 2011 within two ocean-dominated inlets along the South Carolina coast and were measured for size (length, width, height), area of damage, shell thickness, mass, and strength …
Genetic And Genomic Basis Of Antibody Response To Porcine Reproductive And Respiratory Syndrome (Prrs) In Gilts And Sows, Nick V. Serão, Robert A. Kemp, Benny Mote, Philip Willson, John C.S. Harding, Stephen C. Bishop, Graham S. Plastow, Jack C.M. Dekkers
Genetic And Genomic Basis Of Antibody Response To Porcine Reproductive And Respiratory Syndrome (Prrs) In Gilts And Sows, Nick V. Serão, Robert A. Kemp, Benny Mote, Philip Willson, John C.S. Harding, Stephen C. Bishop, Graham S. Plastow, Jack C.M. Dekkers
Department of Animal Science: Faculty Publications
Background: Our recent research showed that antibody response to porcine reproductive and respiratory syndrome (PRRS), measured as sample-to-positive (S/P) ratio, is highly heritable and has a high genetic correlation with reproductive performance during a PRRS outbreak. Two major quantitative trait loci (QTL) on Sus scrofa chromosome 7 (SSC7; QTLMHC and QTL130) accounted for ~40 % of the genetic variance for S/P. Objectives of this study were to estimate genetic parameters for PRRS S/P in gilts during acclimation, identify regions associated with S/P, and evaluate the accuracy of genomic prediction of S/P across populations with different prevalences of …

Water-Quality Effects On Phytoplankton Species And Density And Trophic State Indices At Big Base And Little Base Lakes, Little Rock Air Force Base, Arkansas, June Through August, 2015, L. J. Driver, B. G. Justus
Journal of the Arkansas Academy of Science
Big Base and Little Base Lakes are located on Little Rock Air Force Base, Arkansas, and their close proximity to a dense residential population and an active military/aircraft installation make the lakes vulnerable to water-quality degradation. The U.S. Geological Survey (USGS) conducted a study from June through August 2015 to investigate the effects of water quality on phytoplankton species and density and trophic state in Big Base and Little Base Lakes, with particular regard to nutrient concentrations. Nutrient concentrations, trophic-state indices, and the large part of the phytoplankton biovolume composed of cyanobacteria, indicate eutrophic conditions were prevalent for Big Base …

New Distributional Records Of The Ohio Shrimp, Macrobrachium Ohione Smith (Decapoda: Palaemonidae) In Arkansas, H. W. Robison, L. Lewis, C. Cox, G. Spooner, R. Adams, C. T. Mcallister
Journal of the Arkansas Academy of Science
The Ohio shrimp (Macrobrachium ohione) is a migratory (amphidromous) river shrimp that occurs in some Arkansas rivers. It is known from the Upper Missouri River from its mouth downstream to the Gulf of Mexico, but shrimp abundance has declined, particularly upstream of Louisiana. Ohio Shrimp has also been collected in the lower reach of the Missouri River not far from the confluence of the Mississippi River in St. Louis County. Dams and alterations in channel flow are hypothesized to have impacted upriver migrations of shrimp. Current range, abundance, and life history of Ohio shrimp is relatively unknown in the Mississippi …
Biogeographical Patterns In The Hard-Tick Genus Amblyomma Koch 1844 (Acari: Ixodidae), Matthew H. Seabolt
Biogeographical Patterns In The Hard-Tick Genus Amblyomma Koch 1844 (Acari: Ixodidae), Matthew H. Seabolt
College of Graduate Studies: Theses & Dissertations
Amblyomma Koch is a genus of hard-ticks with approximately 130 species. Its geographical range is typical for organisms with a Gondwanan origin. A majority of these species are endemic to the Neo- and Afrotropical regions, with the remaining taxa dispersed throughout Southeast Asia, Australia and the Pacific islands. Based on this distribution, we hypothesize that the genus dispersal patterns will mirror the fragmentation and continental drift of the Gondwanan supercontinent. Maximum parsimony, maximum likelihood, Bayesian inference and node-dating analyses of nuclear 18S rDNA gene sequences reveal a more recent origin and radiation patterns within the genus and suggest that Amblyomma …
