A New Species Of Vaejovis From Prescott, Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey, Michael E. Soleglad

Euscorpius

A new scorpion species, Vaejovis crumpi, sp. nov., is described from Prescott, Yavapai Co., Arizona. This species is related to V. paysonensis Soleglad, 1973, and the “sky island” species of southern Arizona. V. crumpi is compared to the seven Vaejovis species currently reported for Arizona, in particular to V. paysonensis.

An Assessment Of Stable Hydrogen-Isotope Analysis Methods To Assign Geographic Origin To Migratory Red-Tailed Hawks (Buteo Jamaicensis), Carla Marie Ahlschwede

Department of Environmental Studies: Undergraduate Student Theses

Stable-hydrogen isotopes are becoming an increasingly popular method of studying migratory birds, though sample preparation methods may affect results.  In this study I examined feathers from red-tailed hawks (Buteo jamaicensis) to determine the relationship between measure of δD due to inter-feather variation or drying methods, assessed the accuracy of results by using two birds of known-origin and estimated possible natal origins of migratory red-tailed hawks.  Two feathers per individual were taken from 81 wild hawks caught at Hitchcock Nature Center near Crescent IA and from 2 rescued red-tailed hawks, Raptor Recovery Nebraska near Eagle, NE. 119 of the …

Blarina Hylophaga (Sorciomorpha: Soricidae), Cody W. Thompson, Jerry R. Choate, Hugh H. Genoways, Elmer J. Finck

University of Nebraska State Museum: Mammalogy Papers

Blarina hylophaga (Elliot, 1899) is a soricid commonly called Elliot’s short-tailed shrew. A short-legged, robust shrew with a long, pointed snout and a short tail; it is 1 of 4 species in the genus Blarina. It occurs throughout most of the Great Plains of the United States, where it inhabits moist, well-drained grassland and riparian areas with deep leaf litter. It is listed as a species of greatest conservation need in Iowa and at possible risk in Texas, which might be due to the limited knowledge of the species throughout its geographic range.

A Mark–Recapture Technique For Monitoring Feral Swine Populations, Matthew M. Reidy, Tyler A. Campbell, David G. Hewitt

United States Department of Agriculture Wildlife Services: Staff Publications

Techniques to monitor populations of feral swine (Sus scrofa) relative to damage control activities are needed on rangelands. Our objectives were to describe and assess a mark–recapture technique using tetracycline hydrochloride (TH) for monitoring feral swine populations. We established bait stations at study sites in southern and central Texas. During 1 d, we replaced normal soured corn bait with bait containing TH and counted the number of feral swine that consumed bait with observers. We conducted feral swine removal using box-style traps and helicopters, at which time we collected teeth for TH analysis. In southern Texas, we estimated …

Effects Of Gypsy Moth Outbreaks On North American Woodpeckers, Walter D. Koenig, Eric L. Walters, Andrew M. Liebhold

Biological Sciences Faculty Publications

We examined the effects of the introduced gypsy moth (Lymantria dispar) on seven species of North American woodpeckers by matching spatially explicit data on gypsy moth outbreaks with data on breeding and wintering populations. In general, we detected modest effects during outbreaks: during the breeding season one species, the Red-headed Woodpecker (Melanerpes erythrocephalus), increased over pre-outbreak levels, while during the winter one species, the Yellow-bellied Sapsucker (Sphyrapicus varius), increased and one, the Downy Woodpecker (Picoides pubescens), decreased from pre-outbreak levels. Responses following outbreaks were similarly variable, and in general we were unsuccessful …

Assessing Anglers Identification Of Common Fish Species Of Nebraska, Jason Reed

Department of Environmental Studies: Undergraduate Student Theses

Creel surveys, also known as angler surveys, entail individual interviews with anglers.  The interviews include a variety of questions pertaining to their fishing trip on that particular day. The interviewer asks the angler questions that include, but are not limited to what species they caught that day, the size of the fish, how many hours they spent fishing that day, what bait they were using, etc. If the angler does not know the species caught or misidentifies the species there is the potential for the recorded data to negatively impact management techniques that rely on the creel survey data.                                                                                                        One …

Reliance On Trial And Error Signal Derivation By Portia Africana, An Araneophagic Jumping Spider From East Africa, Robert R. Jackson, Ximena J. Nelson

All Peer-Reviewed Publications

All species from the jumping spider (Salticidae) genus Portia appear to be predators that specialize at preying on other spiders by invading webs and, through aggressive mimicry, gaining dynamic fine control over the resident spider's behavior. From previous research, there is evidence that P. fimbriata, P. labiata and P. schultzi derive signals by trial and error. Here, we demonstrate that P. africana is another species that uses a trial and error, or generate and test, algorithm when deriving the aggressive-mimicry signals that will be appropriate in different predator-prey encounters. We discuss the implications of these new findings and the findings …

Debrazza’S Monkeys (Cercopithecus Neglectus) In A Mixed-Taxa Zoo Exhibit: Effects On The Behavior Of A Breeding Group Of Debrazza’S Monkeys After The Birth Of An Infant, Rachel Diamond

Psychology Honors Projects

Historically, zoos rarely feature mixed taxa exhibits including multiple primate species; the Minnesota Zoo opened such a unique four-species exhibit featuring Rock hyraxes, Red River hogs, Colobus monkeys, and DeBrazza’s monkeys in May, 2010. Because of potential problems associated with territoriality and aggression, primates in mixed-taxa exhibits are generally non-breeding. However, the DeBrazza’s monkeys at the MN Zoo are a breeding pair with a juvenile offspring. The intent of this study was to design an ethogram with the purpose of calculating the effects of a mixed taxa exhibit on the behavior of this breeding group, and to compare their behavior …

Determining The Composition Of The Dwelling Tubes Of Antarctic Pterobranchs, Lukasz J. Sewera

Honors Projects

Pterobranchs are a group of marine invertebrates within the Hemichordata, which share characteristics with both chordates and echinoderms.  Pterobranchs live in colonies of secreted tubes, coenicia, which are composed of a gelatinous material of unknown composition.  Visually, the tubes appear similar to the tunic of tunicates, a group of invertebrates within the Chordata. The nonproteinaceous tunic of tunicates is composed of cellulose, which is unusual.  The goal of this study was to determine the composition of the pterobranch coenicium. Some aspects of pterobranch phylogeny are still unclear even after multiple molecular and morphological studies.  Identification of any new shared characteristics …

The Genus Butheoloides Hirst, 1925 (Scorpiones, Buthidae) In Morocco, With A Description Of А New Species, Wilson R. Lourenço, Oulaid Touloun, Ali Ali Boumezzough

Euscorpius

A new species belonging to the genus Butheoloides Hirst, 1925 (subgenus Butheoloides Hirst, 1925) (Scorpiones, Buthidae) is described from two localities in Morocco: north of Sidi Ifni in the southern coast and Sidi Moussa west of Tiznit. With the description of Butheoloides (Butheoloides) littoralis sp. n., the total number of species of this genus known from Morocco is raised to five. This makes Morocco the region in Africa with the highest diversity for Butheoloides species.

Review Of Cougar: Ecology And Conservation. Edited By Maurice Hornocker And Sharon Negri., Oranit Gilad

Great Plains Research: A Journal of Natural and Social Sciences (through 2013)

Historically, cougars (mountain lions, pumas, or panthers) had an extensive distribution throughout the Americas, ranging from British Columbia in North America to Patagonia at South America's tip. As a native species and a large obligate carnivore, the cougar has a complex relationship with the human population in the Americas. This current book-the product of multiple authors, all with hands-on experience in cougar work, and written in a clear manner appropriate to most audiences-is an important addition to the scientific literature in the field of carnivore conservation in the New World. As a product of many authors, Cougar: Ecology and Conservation …

A Comparison Of Adrenal In Toad-Eating And Nontoad-Eating Snakes, Shabnam Mohammadi

Biological Sciences Theses & Dissertations

Toads are chemically defended by bufadienolides, a class of cardiotonic steroids lethal to most predators, including many snakes. Bufadienolides bind to Na+K +-ATPase, inhibiting their ability to transport ions. In cardiocytes, this inhibition cause arrhythmia and severely increased contraction strength, which, if prolonged, lead to death. However, several snakes are resistant to bufadienolides and consume toads with no ill effects. Adrenal glands produce hormones that are important for the maintenance of Na+K +ATPase, and may therefore play an important role in countering the negative effects of bufadienolides. Indeed, the toad-eating specialist Heterodon platirhinos has been known to possess enlarged, and …

Identification And Characterization Of The Contact Zone Between Short-Tailed Shrews (Blarina) In Iowa And Missouri, Cody W. Thompson, R. S. Pfau, Jerry R. Choate, Hugh H. Genoways, Elmer J. Finck

University of Nebraska State Museum: Mammalogy Papers

Short-tailed shrews (genus Blarina Gray, 1838) are characterized by divergent karyotypes and are genetically distinct. Blarina species are similar morphologically but, in most cases, can be distinguished morphometrically. Blarina distributions tend to be parapatric along well-defined contact zones; however, it has been suggested that the northern short-tailed shrew (Blarina brevicauda (Say, 1823)) and Elliot’s short-tailed shrew (Blarina hylophaga Elliot, 1899) occur sympatrically in Iowa and Missouri. To evaluate this possibility, 179 specimens were collected in southwestern Iowa and northwestern Missouri. Karyotypes and total length were used for field identification, and amplified fragment length polymorphism (AFLP) analysis was used …

Multilocus And Parametric Analyses Of The Evolutionary History Of The Amazonian Peacock Cichlids, The Genus Cichla (Teleostei: Cichlidae), Stuart Clayton Willis

School of Biological Sciences: Dissertations, Theses, and Student Research

Accurate knowledge of species boundaries and species phylogeny are fundamental to testing hypotheses of recent evolutionary processes, but the estimation of these partitions is challenging due both to inherent confusion about what is being estimated as well as the data available to estimate them. Using multilocus data from mtDNA, microsatellites, and nuclear locus sequences of over 1100 individuals, we delimited eight separately evolving species of Cichla rather than the 15 described. Among species we found evidence of rare but widespread introgressive hybridization, while within these species we observed evidence of long-term gene exchange and constrained evolutionary trajectories. In most cases …

A Molecular Phylogeny Of Living Primates, Polina L. Perelman, Warren E. Johnson, Christian Roos, Hector Seuanez, Julie E. Horvath, Miguel A. M. Moreira, Bailey Kessing, J. U. Pontius, Melody E. Roelke, Yves Rumpler, Maria P. C. Schneider, Artur Silva, Stephen J. O'Brien, Jill Pecon-Slattery

Biology Faculty Articles

Comparative genomic analyses of primates offer considerable potential to define and understand the processes that mold, shape, and transform the human genome. However, primate taxonomy is both complex and controversial, with marginal unifying consensus of the evolutionary hierarchy of extant primate species. Here we provide new genomic sequence (~8 Mb) from 186 primates representing 61 (~90%) of the described genera, and we include outgroup species from Dermoptera, Scandentia, and Lagomorpha. The resultant phylogeny is exceptionally robust and illuminates events in primate evolution from ancient to recent, clarifying numerous taxonomic controversies and providing new data on human evolution. Ongoing speciation, reticulate …

A Late-Season Breeding Record For The Summer Tanager In Nebraska, Eric C. Hopps

Nebraska Bird Review

The breeding range of the Summer Tanager (Piranga rubra) is well documented and expands across the southern U.S. extending northward to New Jersey and west along and south of the Great Lakes to the eastern edge of the Great Plains (Terres 1991; Robinson 1996). In Nebraska the species is generally confined to the Lower Missouri and Platte River Valleys where it occurs locally (Sharpe et al. 2001). Because the species exists in relatively low numbers across southeastern Nebraska, there are few breeding and nesting records for the state. Fewer than 10 breeding records, including one historical account have …

Book Review [Of Wild Birding Colorado: The Big Year Of 2010], W. Ross Silcock

Nebraska Bird Review

Nebraska birders might remember seeing reports posted to NEBirds a few years back by Cole Wild, a native Coloradan whose mother's family is from Nebraska. Cole took up birding at age 19, spurred by an earlier high school environmental science class that required identification of 100 species of birds. As with many of us, a brightly plumaged bird, in this case a Western Tanager, resulted in "the birdwatching gene" in Cole suddenly being "switched to the ON position." Soon after, Cole went on a "what the heck, I'll try it" field trip to see a Kelp Gull at Loveland Reservoir …

2010–2011 Christmas Bird Counts, Don Paseka

Nebraska Bird Review

Fourteen Christmas Bird Counts were held in Nebraska in the 2010–2011 season. The Branched Oak–Seward count was canceled due to weather, but in comparison to last year, the weather was generally dry, mild, and cooperative. Even though open water was limited, the species associated with water were well represented, resulting in the highest total number of species (149) ever, easily topping the previous high count of 138 in 2001. In all, 17 species set new high counts, 5 tied previous highs, and the amazing Brown-headed Nuthatches stayed in Lincoln and were counted for the first time in Nebraska.

Twelve species …

Winter Field Report, December 2010 To February 2011, W. Ross Silcock

Nebraska Bird Review

This winter was pretty much a rerun of last, although perhaps not as severe; I could have used last winter's Introduction again. If there was an overall theme, it would be the widespread occurrences of species that would not be expected to linger into late December and January. Several species of waterbirds, notably Blue-winged Teal, scoters, Ruddy Duck, Common Loon, and Homed and Red-necked Grebes were in this category. Large numbers of Western Grebes were still at Lake McConaughy in early January, and surprisingly late individuals of Black-crowned Night-Heron and Plegadis ibis were located. Mourning Doves were in good numbers …

Book Review [Of The Stokes Field Guide To The Birds Of North America], Tim Hajda

Nebraska Bird Review

Don and Lillian Stokes are well known for their nature guides that cover a variety of subjects, from hummingbirds and beginner shorebird identification to reptiles and amphibians. Their original pair of Stokes Field Guide to Birds: Eastern Region and Western Region have remained popular among North American birders since their appearance in 1995. They were illustrated with photographs instead of the traditional paintings used in most field guides. The authors' latest book, The Stokes Guide to Birds of North America is essentially an entirely new and much improved version of these two guides. Instead of being split into two books, …

Factors Affecting Space Use Overlap By White-Tailed Deer In An Urban Landscape, W. David Walter, Jeff Beringer, Lonnie P. Hansen, Justin W. Fischer, Joshua J. Millspaugh, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Variation in the size and overlap of space use by white-tailed deer (Odocoileus virginianus) has broad implications for managing deer–human conflicts and disease spread and transmission in urban landscapes. Understanding which factors affect overlap of home range by various segments (i.e., age, sex) of an urban deer population has implications to direct contact between deer on disease epidemiology. We assessed size of home range and overlap of space use using the volume of intersection index (VI) for deer in an urban landscape by sex, age, season, and time of day. We found mean space use was larger for …

Contributions To Scorpion Systematics. Iv. Observations On The Hadrurus “Spadix” Subgroup With A Description Of A New Species (Scorpiones: Caraboctonidae), Michael E. Soleglad, Victor Fet, Graeme Lowe

Euscorpius

In this study new data are presented on the “spadix” subgroup of genus Hadrurus, including the description of a new species, H. anzaborrego, sp. nov., found primarily in the Anza-Borrego Desert State Park (ABDSP) in southern California, USA. This species is distinguished by its internal trichobothrial pattern of the chela and its unique carapace pattern. The status of Hadrurus obscurus Williams, 1970 is discussed and new locality data for this species are provided. A phylogenetic key to the genera, species, and subspecies of subfamily Hadrurinae is provided.
