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 …

A new species is described belonging to the genus Chaerilus Simon, 1877. Chaerilus andamanensis sp. n. was discovered in the Island of Little Andaman in the Indian Ocean. The new species shows affinities with Chaerilus variegatus Simon, 1877 and Chaerilus borneensis Simon, 1880, respectively described from Java and Borneo. This s the first record of the genus Chaerilus in the Andaman Islands.

On Two Subspecies Of Mesobuthus Eupeus (C. L. Koch, 1839) In Turkey (Scorpiones: Buthidae), František Kovařík, Ersen Aydın Yağmur, Victor Fet, Shahrokh Navidpour

Euscorpius

Examination of 268 specimens of Mesobuthus eupeus eupeus (C. L. Koch, 1839) and 1765 specimens of M. eupeus phillipsii (Pocock, 1889) from 163 localities, 92 of them in Turkey, has enabled us to establish distribution of the two subspecies and limits of their ranges in southeastern Turkey. A map of distribution of these subspecies in Turkey and a key to Turkish Mesobuthus species and subspecies are provided. Buthus eupeus philippovitschi Birula, 1905 is synonymized with Mesobuthus eupeus eupeus, and Buthus eupaeus mesopotamicus Penther, 1912 is synonymized with Mesobuthus eupeus phillipsii.

Compsobuthus Sindicus Sp. N. From Pakistan (Scorpiones: Buthidae), František Kovařík, Zubair Ahmed

Euscorpius

Compsobuthus sindicus sp. n. of the werneri group is described from Pakistan, Sind Province, near the border with India. It is characterized chiefly by densely granulated carapace mesosoma, metasoma, telson, and femur and patella of pedipalps; the first to fourth metasomal segments bear 10 carinae. C. sindicus sp. n. is closest to C. rugosulus (Pocock, 1900) from India and Pakistan, from which it differs chiefly in having the first metasomal segment approximately as wide as long.

Regulated Commercial Harvest To Manage Overabundant White-Tailed Deer: An Idea To Consider?, Kurt C. Vercauteren, Charles W. Anderson, Timothy R. Van Deelen, David Drake, W. David Walter, Stephen Vantassel, Scott E. Hygnstrom

United States Department of Agriculture Wildlife Services: Staff Publications

Declines in hunter recruitment coupled with dramatic growth in numbers of white-tailed deer (Odocoileus virginianus) have challenged our ability to manage deer populations through regulated hunting. We review the efficacy of current regulated hunting methods and explain how they are unable to reduce deer numbers sufficiently in some environments. Regulated commercial harvest would provide an additional tool to help state wildlife agencies manage overabundant populations of white-tailed deer. We outline potential means to govern regulated commercial deer harvest and explain how it is compatible with the North American Model of Wildlife Conservation. We identified several benefits, including reduced …

A Comparison Of Prairie Vole Audible And Ultrasonic Pup Calls And Attraction To Them By Adults Of Each Sex, Thomas A. Terleph

Biology Faculty Publications

Rodent pups of many species emit both ultrasonic vocalizations (USVs) and calls spanning into a lower frequency range, audible to humans (AUDs), yet there has been little systematic comparison of these different call types, or analyses of how they might differ in signal function. Here the spectral and temporal characteristics of USV and AUD pup calls are described for the prairie vole (Microtus ochrogaster), a model used in studies of monogamous mating and biparental care, and a species with an unusually large functional and anatomical representation of auditory cortex. Findings provide a detailed description of each call type, …

The Need To Quantify Ecosystem Services Provided By Birds, Daniel G. Wenny, Travis L. Devault, Matthew D. Johnson, Dave Kelly, Cagan H. Sekercioglu, Diana F. Tomback, Christopher J. Whelan

United States Department of Agriculture Wildlife Services: Staff Publications

What are the birds worth--what is their actual dollar value to human society? To most of us in the ornithological community, birds are invaluable. But in these times we need more specific rationales to convince policy makers and business leaders to include bird conservation in land-use and development decisions. Over the past two decades, awareness of our dependence on a variety of ecosystem services (natural ecological processes that benefit human society) and of their importance and prevalence has progressed toward the goal of making conservation a mainstream value. Building strategies for the protection of ecosystem services into conservation and land-use …

Phylogeography Of Northern Populations Of The Black-Tailed Rattlesnake (Crotalus Molossus Baird And Girard, 1853) With The Revalidation Of C. Ornatus Hallowell, 1854, Christopher Anderson

Open Access Theses & Dissertations

The black-tailed rattlesnake (Crotalus molossus Baird and Girard, 1853) is a wide-ranging species complex with representatives from the southwestern United States through the highlands of central and southern Mexico. The systematics of this group has received little attention and in the past six decades only two taxonomic revisions have been proposed (the transfer of C. basiliscus oaxacus to C. molossus and the elevation of C. m. estebanensis to full species). However, a recent revision of the Neotropical rattlesnakes (C. durissus and C. simus) recovered a polyphyletic C. molossus. Sequenced data were obtained from three mitochondrial genes …

The Status Of Dwarfed Populations Of Short-Horned Lizards (Phrynosoma Hernandesi) And Great Plains Toads (Anaxyrus Cognatus) In The San Luis Valley, Colorado, Megan E. Lahti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The San Luis Valley is a large valley formation in Colorado surrounded on either side by mountain ranges exceeding 4,267 m. Within the Valley, two of the 14 amphibian and reptile species are dwarfed: the short-horned lizard (Phrynosoma hernandesi) and the Great Plains toad (Anaxyrus cognatus). Since its initial reporting in 1968 and confirmation in 1981, no research further investigating this dwarfism has been conducted. I collected morphological measurements to determine the extent and patterns of dwarfism of both species. I then investigated the genetics of both species using mitochondrial DNA to determine whether they are …

Description Of The Tadpole Of Proceratophrys Renalis (Miranda-Ribeiro, 1920) (Anura: Cycloramphidae), Filipe Augusto C. Do Nascimento, Barnagleison S. Lisboa, Gabriel O. Skuk, Rafael O. De Sá

Biology Faculty Publications

The tadpole of Proceratophrys renalis is described based on specimens from Maceió, State of Alagoas, northeastern Brazil. At stage 35 the body is slightly dorso-ventrally depressed, ovoid in lateral, dorsal, and ventral views. Oral disc is ventral with lateral emarginations, surrounded by a single row of marginal papillae with a large gap on the upper labium. Labial tooth row formula is 2(2)/3(1 ). The analysis of internal oral anatomy revealed two possible characters that readily distinguish P. renalis from P. boiei, supporting the recent resurrection of P. renal is. Comparisons with available descriptions of the larvae for other species in …

Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone

Department of Environmental Studies: Undergraduate Student Theses

The choice of a specific microhabitat represents a compromise among a number of different factors organisms use to monitor habitat suitability. Grassland vegetation structure can vary widely along environmental gradients over a relatively small area. This vegetation structure can have a large influence on habitat selection by grasshoppers (Orthoptera). However, it is not clear which vegetation characteristics are most important in determining grasshopper abundance. We found that plant biomass, plant species richness, and plant quality all have an effect on grasshopper abundance and distribution. We observe that these affects vary both within and among the two years of data collection. …

Reconstructing Species Responses To Past Climatic Changes Using Niche Modeling And Genetic Data, Tereza Jezkova

UNLV Theses, Dissertations, Professional Papers, and Capstones

Glacial – interglacial cycles have a pronounced impact on species distributions and genetic structure. Many species shift their distributions to lower latitudes and altitudes during the colder glacial periods and expand northwards and up the elevation during warmer interglacial periods. Some species however are capable of adapting to changing environment which allows them to persist in place despite climatic changes. I explored how climatic changes after the last glacial maximum (LGM) effected two species inhabiting the deserts of western North America: one mammal (Chisel-toothed Kangaroo Rat, Dipodomys microps) and one reptile (Desert Horned Lizard, Phrynosoma platyrhinos). I used …

Match–Mismatch Regulation For Bluegill And Yellow Perch Larvae And Their Prey In Sandhill Lakes, Jeffrey C. Jolley, David W. Willis, Richard S. Holland

Nebraska Game and Parks Commission: Staff Research Publications

Food availability may regulate fish recruitment, both directly and indirectly. The availability of zooplankton, especially to newly hatched larvae, is thought to be crucial to their early growth and survival. We examined stomach contents of larval bluegill Lepomis macrochirus and yellow perch Perca flavescens in Pelican Lake and Cameron Lake, Nebraska, in 2004 and 2005. We also determined zooplankton availability and calculated prey selection using Chesson’s a. In addition, we investigated potential match–mismatch regulation of recruitment from 2004 to 2008. Bluegill positively selected copepod nauplii and Bosmina spp., and yellow perch often selected copepods. Abundant zooplankton populations were available for …

Osteology, Natural History Notes, And Phylogenetic Relationships Of The Poorly Known Caribbean Frog Leptodactylus Nesiotus (Anura, Leptodactylidae), María Laura Ponssa, Michael J. Jowers, Rafael O. De Sá

Biology Faculty Publications

The Leptodactylus melanonotus group consists of 15 species, but references to skeletal characters are available for only three species: L. leptodactyloides, L. melanonotus, and L. diedrus. Leptodactylus nesiotus is a member of the melanonotus group known only from the type locality, Bonasse swamp, on the Southwestern peninsula of Trinidad, Trinidad and Tobago. This species has been categorized as vulnerable given its restricted distribution. Herein, we report the adult osteology of L. nesiotus, the skeletal characters are compared with the available data from other Leptodactylus species. A phylogenetic analysis recovers a paraphyletic L. melanonotus group relative to the L. …

The Identity Of The Crackling, Luminescent Frog Of Suriname (Rana Typhonia Linnaeus, 1758) (Amphibia, Anura), E. O. Lavilla, José A. Langone, José M. Padial, Rafael O. De Sá

Biology Faculty Publications

Review of the literature and recently available field notes from the collector of the type allows a reconsideration of the identity of the Linnaean name Rana typhonia. We provide evidence to demonstrate that the Linnaean species is neither a bufonid nor an Asiatic ranid, but a Neotropical hylid. Subsequently, we consider Rana typhonia as an older synonym of Rana venulosa Laurenti, 1768, redescribing its holotype under the new combination, Trachycephalus typhonius (Linnaeus, 1758).

The Identity Of Zachaenus Roseus Cope, 1890 (Anura: Species Inquirenda), Esteban O. Lavilla, J. J. Nuñez, F. E. Rabanal, José A. Langone, Rafael O. De Sá

Biology Faculty Publications

Zachaenus roseus Cope, 1890, has puzzled systematists working in southern South America. A single individual, the holotype, has ever been collected and this specimen is in extremely poor preservation condition. Herein, the precise location of the type locality of Z. roseus is determined based on a historical review of the literature. Furthermore, following a careful comparison with all species that inhabit the southern austral forest, and that could potentially correspond to Zachaenus roseus, we conclude that this taxon is placed in the synonymy of Eupsophus calcaratus (Günther, 1881)

University of Nebraska State Museum: Mammalogy Papers

Almost nothing is known concerning the chiropteran fauna on the Grenadine Islands, a chain of islands between St. Vincent and Grenada located near the southern end of the Lesser Antilles. Previously, only a single species—Glossophaga longirostris—had been reported from the Grenadines. Our research, conducted on 4 occasions over the period of 1980 to 2006, provided museum vouchers and genetic specimens for the addition of 4 other species to the known fauna of these islands—Noctilio leporinus, Artibeus lituratus, Artibeus schwartzi, and Molossus molossus. The Grenadines, being situated between St. Vincent and Grenada, occupy an important zoogeographic position. …

Comparative Ecology Of Narrowly Sympatric Horned Lizards Under Variable Climatic Conditions, Kevin V. Young

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

We studied the Flat-tailed Horned Lizard, Phrynosoma mcallii, and the Sonoran Horned Lizard, P. goodei, in an area of narrow sympatry near Yuma, Arizona, and found they overlapped broadly in use of available food resources, body size, and growth rates. We compared diet (Chapter 2), growth and reproduction (Chapter 3), and survivorship (Chapter 4) of P. mcallii and P. goodei during two years of drought followed by a year of higher-than-average rainfall. We predicted that P. mcallii would be more tolerant of drought conditions than its congener, since P. mcalliiis found only in an extremely arid region while …
