First Record Of The Genus Compsobuthus (Scorpiones: Buthidae) From Maharashtra, India, With Description Of A New Species, Vivek Waghe, Satpal Gangalmale, Akshay Khandekar
First Record Of The Genus Compsobuthus (Scorpiones: Buthidae) From Maharashtra, India, With Description Of A New Species, Vivek Waghe, Satpal Gangalmale, Akshay Khandekar
Euscorpius
A new species of the genus Compsobuthus Vachon, 1949 (Buthidae) belonging to the werneri group is described from two localities in Jalgaon District, Maharashtra, India. The new species can be easily distinguished from all four members of the werneri group known from India and Pakistan by combination of nonoverlapping morphological characters. Compsobuthus satpuraensis sp. n. is the first species of this genus to be reported from the state of Maharashtra and fourth to be reported from India.
Observations On Regeneration Of The Pedipalp And Legs Of Scorpions, Martin Watz, Jason A. Dunlop
Observations On Regeneration Of The Pedipalp And Legs Of Scorpions, Martin Watz, Jason A. Dunlop
Euscorpius
An Opisthacanthus asper (Peters, 1861) (Hormuridae) shows a relatively rare example of pedipalp regeneration in which the lost tibia and tarsus was replaced by a smaller, curved element of uncertain homology to either the fixed or free finger. A comparable abnormal palp described in the literature hints that pedipalps can only regenerate a structure of this form, regardless of the site of amputation. An Olivierus caucasicus (Nordmann, 1840) (Buthidae) is described in which claws (pretarsus) of leg III regenerated directly at the distal end of the tibia, while in leg IV the claws regenerated at the end of a truncated …

Using Occupancy Modeling For Protocol Development And Habitat Assessment Of Necturus Maculosus In A Large Nagivational River, Alyssa Rachelle Jones
Theses, Dissertations and Capstones
Determining the survey effort required to reliably detect population change can be challenging for cryptic, elusive species. The secretive nature of amphibians makes it difficult to monitor population status and gather information about their natural history, including habitat use, which is essential for amphibian monitoring programs. The goals of this study were to examine if detection probabilities were affected by bait (i.e., light and food), breeding activity, and environmental covariates in a population of fully aquatic salamanders, Necturus maculosus. I evaluated the effectiveness of three bait treatments (light bait, food bait, combined light and food bait) and an unbaited …
Ephemeroptera Culturing Methods: An Analysis On Rearing And Toxcity Testing On Sensitive Early Life Stages Of Native Mayfly Taxa, Geneve Rainette Edwards
Ephemeroptera Culturing Methods: An Analysis On Rearing And Toxcity Testing On Sensitive Early Life Stages Of Native Mayfly Taxa, Geneve Rainette Edwards
Theses, Dissertations and Capstones
Standard toxicity testing organisms are utilized for regulatory purposes and often ecological risk assessments. Ephemeroptera taxa have been reported to be more sensitive to aquatic contaminants than the standard toxicity testing organisms currently used in determining effects on aquatic ecosystems. Establishing methods for culturing native Ephemeroptera taxa will provide a more sensitive test organism to determine the toxicity of contaminants and will be more representative of the responses of native taxa. Additionally, it will provide a test organism at the most sensitive life stages. The objective of this research is to develop methods for culturing and testing of native Ephemeroptera …
Translocation Of Timber Rattlesnakes At Two West Virginia State Forests, Elizabeth Morgan Johnson
Translocation Of Timber Rattlesnakes At Two West Virginia State Forests, Elizabeth Morgan Johnson
Theses, Dissertations and Capstones
In wildlife management, translocation is defined as the purposeful movement of an individual(s) from one place to another with a wildlife management goal. Translocation has become a common tool for mitigating negative human-wildlife interactions. We conducted a translocation study on timber rattlesnakes (Crotalus horridus) in response to numerous human-rattlesnake encounters with the goal of developing a translocation protocol that would allow natural resources personnel to mitigate negative encounters between the public and rattlesnakes and reduce impacts to local timber rattlesnake populations. In this study, we scaled translocation distance to site-specific home range characteristics to assess whether translocation outcomes …
Ephemeroptera Culturing Methods: Development Of Culturing And Rearing Methodology And High Sulfate Simulated Mine Effluent Toxicity Test Using Field Collected Water, Daniel Edward Brady
Ephemeroptera Culturing Methods: Development Of Culturing And Rearing Methodology And High Sulfate Simulated Mine Effluent Toxicity Test Using Field Collected Water, Daniel Edward Brady
Theses, Dissertations and Capstones
Ephemeroptera taxa are not frequently used in toxicity testing; however, some mayfly taxa may be more sensitive to aquatic pollutants than standard test organisms used to determine anthropogenic effects on aquatic ecosystems. Additionally, some standard test organisms are not native to the Appalachian region and may not be truly reflective of the effects on native organisms. With mayflies not being the typical test organism, there is not a great deal of literature on culturing methods for this organism. For a standard acute toxicity test, there must be 80% survival within the control organisms for the test to be considered viable. …
Mortality Risk Associated With Urban Land Use For Adult Eastern Diamondback Rattlesnakes (Crotalus Adamanteus), Mya Wiles
Theses, Dissertations and Capstones
Snakes have been a traditionally under-represented organism in urban ecology, but they face similar, if not greater challenges in the face of growing urban sprawl. Eastern diamondback rattlesnakes (Crotalus adamanteus, EDBs) are under consideration for listing under the Endangered Species Act due to population declines resulting from historical human persecution and habitat loss. This study used radio-telemetry data from a long-term monitoring project of adult EDBs on a developed sea island in South Carolina, USA. I reclassified a National Land Cover Dataset to reflect relative mortality risk for snakes attempting to move through the landscape. High-risk cover types …

Amphibians And Reptiles As Prey Of Heteroctenus Junceus (Scorpiones: Buthidae), With A Summary Of Vertebrate Predation By Scorpions In The West Indies, Tomás M. Rodríguez-Cabrera,, Ernesto Morell Savall, Rolando Teruel
Euscorpius
Vertebrate predation by scorpions has been scarcely documented in the literature. Contrary to large scorpions of the genera Centruroides, Hadrurus, Opistophthalmus, and Pandinurus from North America and Africa, which are capable of subduing even small rodents and bats, West Indian scorpions of the genera Centruroides, Heteroctenus, and Tityus seem to limit their prey to amphibians and reptiles. Herein we present new cases of a frog (Osteopilus septentrionalis; Hylidae) and three lizards (Anolis allisoni, A. ophiolepis, and A. sagrei; Dactyloidae) preyed upon by Heteroctenus junceus (Herbst, 1800), at the time we summarize all cases of vertebrate …

The First Troglobitic Scorpions From Hispaniola, Greater Antilles: Two New Species Of Cazierius Francke, 1978 (Scorpiones: Diplocentridae), Rolando Teruel, Solanlly Carrero Jiménez, Gabriel De Los Santos
Euscorpius
Two new species of the Greater Antillean endemic scorpion genus Cazierius Francke, 1978, are herein described from the island of Hispaniola. They were found inside isolate limestone caves in the Dominican Republic and are fully troglomorphic, thus, apparently being strict troglobites that represent the first ever documented for this genus. The present additions raise the number of Hispaniolan species of both Cazierius and the family Diplocentridae Karsch, 1880, to five and ten, respectively.

The Correct Identity Of Centruroides Hoffmanni Armas, 1996 (Scorpiones: Buthidae), With The Description Of A New Species From Chiapas, Mexico, Luis De Armas, Rolando Teruel
Euscorpius
The Mexican scorpion Centruroides hoffmanni Armas, 1996 was described on the basis of a supposed adult female (actually a juvenile) from La Gloria, Arriaga Municipality, southwest of the Chiapas State. In its redescription, this species was also recorded from the southeastern of Oaxaca State. Nevertheless, in the recent revision of the “thorellii” species-group of the genus Centruroides Marx, 1890, a new species from Chiapas was misidentified as C. hoffmanni and, also, an erroneous new diagnosis was given for C. hoffmanni. In the present contribution, this new species is named Centruroides concordia sp. n., and the correct identity of C. …

Somalibuthus Sabae Sp. N., A New Buthid Scorpion From Kenya (Scorpiones: Buthidae), František Kovařík, Laban Njoroge
Euscorpius
The poorly known buthid genus Somalibuthus Kovařík, 1998, is recorded for the first time from Kenya, with the description of a new species, S. sabae sp. n., from Kiwayu Island in the Kiunga Marine National Reserve. Based on a detailed study of the new materials, a revised diagnosis is given for the genus. Several generic characters suggest affinities with three other genera of small buthids found in the Horn of Africa: Neobuthus Hirst, 1911, Gint Kovařík, Lowe, Plíšková et Šťáhlavský, 2013, and Lanzatus Kovařík, 1998.
Habitat Characteristics Of Two Scorpion Species, Liocheles Australasiae (Fabricius, 1775) And Isometrus Maculatus (De Geer, 1778) In Miyako Islands, Japan, Kazusa Kawai
Euscorpius
Scorpion surveys were conducted in the five islands: Miyakojima, Ikemajima, Kurimajima, Irabujima, and Shimojishima (Miyako Islands, part of Nansei/Ryukyu Islands of Japan). Eight individuals of Liocheles australasiae (Hormuridae) and 16 individuals of Isometrus maculatus (Buthidae) were observed in a total of 10 points on four islands, except Ikemajima. The localities of both species are recorded in this survey, focusing on altitude, distance from the nearest coast, and sunlight. The lowest temperatures in the habitat are also examined, and the cold tolerance of the species is discussed.

Seasonal Variation In Home-Range And Core-Area Size In Verreaux's Sifaka, Brynn Harshbarger
Seasonal Variation In Home-Range And Core-Area Size In Verreaux's Sifaka, Brynn Harshbarger
Theses, Dissertations and Capstones
Primates living in seasonal forests must adapt to extreme fluctuation in resource availability. Verreaux’s sifaka ( ) live in Madagascar’s highly seasonal tropical dry forests and experience periods of extreme resource abundance and scarcity. Home- range and core-area size were measured using 95% and 50% kernel estimation, and 95% minimum convex polygons to compare seasonal shifts in space use based on resource availability. There have been no long-term space use studies on Verreaux’s sifaka; therefore, we do not know how their space use changes over time in an environment which is both highly seasonal and highly variable. Our study leverages …
Assessing The Toxicity Of A Reconstituted Water Simulating Streams Influenced By Mountaintop Mining In Central Appalachia, Benjamin David Browning
Assessing The Toxicity Of A Reconstituted Water Simulating Streams Influenced By Mountaintop Mining In Central Appalachia, Benjamin David Browning
Theses, Dissertations and Capstones
Freshwater ecosystems in Central Appalachia experience increased concentrations of manganese (Mn) and total dissolved solids from the runoff of surface mines and valley fills. Biological communities have been impacted by these surface mining operations and it has been suggested that the increase in total dissolved solids may contribute to these negative effects, but standard laboratory toxicity tests have not found increased concentrations of total dissolved solids to have such negative effects as seen in the field. The elevated total dissolved solids in mining influenced streams may only be toxic in conjunction with another toxicant that is presence in these systems …
The Effects Of Fire On Oak-Forest Plant Communities Along Soil Moisture Gradients: A 25-Year Study, Rebekah Frances Shupe
The Effects Of Fire On Oak-Forest Plant Communities Along Soil Moisture Gradients: A 25-Year Study, Rebekah Frances Shupe
Theses, Dissertations and Capstones
In the eastern U.S., fire is a natural disturbance process in Quercus (oak) forests. Fire is thought to promote oak regeneration and plant diversity by reducing competition, preparing a suitable seedbed, and increasing light availability. However, the era of fire suppression that began in the early 20th century is thought to have negatively impacted oak regeneration and the biodiversity of the understory layer. In this study, we examined the effects of prescribed fire on tree regeneration and the understory layer over 25 years. From a study initiated in 1994, we resampled 45 permanent vegetation plots measuring 1250 m2 …

An Exceptionally Small New Polycotylid Plesiosaur (Reptilia: Sauropterygia) With Raptorial Eyes From The Western Interior Seaway Of North America, Robert O’Brien Clark
Theses, Dissertations and Capstones
Polycotylidae is a family of plesiosaurian marine reptiles that evolved during the Early Cretaceous and radiated into multiple genera during the Late Cretaceous, achieving a worldwide distribution. Derived polycotylids of the subclade Polycotylinae have a gracile and elongated rostrum, homodont dentition, an extended mandibular symphysis, and foreshortened temporal fenestrae. In this thesis, I describe a small and highly derived new polycotylid taxon based on three specimens from the Campanian of the Western Interior Seaway in North America. A high number of maxillary teeth, fused neural arches, propodials with well-defined facets, and heavily remodeled cortical bone indicate the specimens are adults, …
