The Presence Of Micropterus Salmoides (Largemouth Bass) Influences The Populations Of Rana Draytonii (California Red-Legged Frog) And Pseudacris Regilla (Pacific Treefrog) In Two Ponds In Santa Barbara County, California, Kenneth Lee Gilliland

Master's Theses

Alien fish have been implicated in the decline of Rana draytonii (California red-legged frog) and Pseudacris regilla (Pacific treefrog) populations. Micropterus salmoides (largemouth bass) is a common sport fish that has been introduced into the sympatric range of these two anuran species; however, no studies have investigated the individual influence that this alien fish has on these two species. I conducted M. salmoides control or eradication experiments during a four year study in two ponds within the Transverse Mountain Range of Santa Barbara County, California. Changes in the densities of all life stages of R. draytonii and P. regilla were …

• estimates of the regional economic and population impact for a range of fishing industry scenarios arising from the …

The Identification Of Rana Ocellata Linnaeus, 1758. Nomenclatural Impact On The Species Currently Known As Leptodactylus Ocellatus (Leptodactylidae) And Osteopilus Brunneus (Gosse, 1851) (Hylidae), Esteban O. Lavilla, José A. Langone, Ulisses Caramaschi, W. Ronald Heyer, Rafael O. De Sá

Biology Faculty Publications

The usage of the name Rana ocellata Linnaeus, 1758, is plagued by misidentifications and misinterpretations. After an exhaustive bibliographic review, we conclude that the Linnaeus 1758 name refers to Osteopilus brunneus (Gosse, 1851) from Jamaica, while the taxon currently known as Leptodactylus ocellatus corresponds to Rana latrans Steffen, 1815. Herein, we designate and provide descriptions of the neotypes of Leptodactylus latrans (Steffen, 1815), revalidated, new combination, and Osteopilus ocellatus (Linnaeus, 1758), new combination, as a senior synonym of Osteopilus brunneus (Gosse, 1851).

Leptodactylus Cunicularius, W. R. Heyer, Miriam M. Heyer, Rafael O. De Sá

Biology Faculty Publications

Adult Leptodactylus cunicularius are moderately small. The head is longer than wide and the hind limbs are long (Table 1; Heyer and Thompson 2000 provided definitions of adult size and leg length categories for Leptodactylus). Male vocal sacs are internal, not externally expanded. The snout is protruding, not sexually dimorphic. Male forearms are not hypertrophied and males lack asperities on the thumbs and chest. The dorsum is variegated with small, often confluent, spots and blotches. There is a very thin interrupted mid-dorsal light stripe (pinstripe). Usually, there is a noticeable light, irregular, elongate, mid-dorsal blotch in the scapular region. The …

Leptodactylus Syphax, W. R. Heyer, Miriam M. Heyer, Rafael O. De Sá

Biology Faculty Publications

Adult Leptodactylus syphax are moderately sized (males 58-83 mm, females 70-90 mm SVL). The head is about as long as wide, but usually is just wider than long. The hind limbs are moderately short (Table 1; Heyar and Thompson 2000 provided definitions of adult size and leg length categories for Leptodactylus). Male vocal sacs are laterally expanded, tan, and not darker than the adjacent throat. The male snout is not spatulate, the snout profile is rounded to obtuse in both sexes. Male arms are hypertrophied during the breeding season in sexually active males. The male thumb has two large, …

A Habitat Model For The Detection Of Two-Lined Salamanders At C. F. Phelps Wildlife Management Area, Fauquier And Culpeper Counties, Virginia, Jay Mcghee, Michael D. Killian

Virginia Journal of Science

Aquatic salamanders represent an important component of Virginia river watersheds, but despite potential declines, few specifics are known about their habitat preferences. We surveyed the habitats of the northern two-lined salamander and collected data on an array of habitat variables associated with the species. We used a logistic regression analysis to develop a model predicting its presence or absence for a given 50m-transect. Our final model incorporated the variation in stream depth and direction of stream flow and accounted for 25% of the variation in our data. We conclude that stream depth variation is an important feature of salamander habitat …

Impacts Of Shoreline Development On The Littoral Zone Of Great Pond, Problems In Environmental Science Course (Biology 493), Colby College, Colby Environmental Assessment Team, Colby College

Colby College Watershed Study: Great Pond (2012, 2010, 1998)

The Colby Environmental Assessment Team (CEAT) investigated the littoral zone of Great Pond in the Belgrade Lakes region of central Maine. Data collection occurred in September and October and analysis followed in October and November of 2010. Physical, biological, and chemical parameters were assessed to examine the impacts of shoreline development on the health of the littoral community. The littoral zone and adjacent riparian areas were sampled to allow comparison of aquatic and terrestrial parameters among different levels of shoreline development.

The Natural History & Distribution Of Riverine Turtles In West Virginia, Linh Diem Phu

Theses, Dissertations and Capstones

Turtles are unique evolutionary marvels that evolved from amphibians and developed their protective shelled form more than 200 million years ago. In West Virginia, there are 10 native species of turtles, 9 of which are aquatic. Most of these aquatic turtles feed on carrion and dead plant matter, in the water and essentially "clean" our water systems. Turtles are long-lived animals with sensitive life stages that can serve as both long-term and short-term bioindicators of environmental health. With the increase in commercial trade, habitat fragmentation, degradation, destruction, there has been a marked decline in turtle species. The need for well …

The Coal River Basin: A 2009 Water Budget Study, R. Dale Biller

Theses, Dissertations and Capstones

The Coal River Watershed covers an area of some 890 square miles in southern West Virginia of which 863 square miles was investigated in this study. Both online and field data were collected over period from January 13, 2009 to January 13, 2010. The basin was studied as a closed system having an input, which was precipitation, and outputs, rainfall interception, evapotranspiration, and stream discharge that was separated into base flow and overland flow.

The effective rainfall of the watershed was calculated using the Thiessen polygon method to be 42 inches for the year, 48% of that water discharged by …

A Sketch-Based Language For Representing Uncertainty In The Locations Of Origin Of Herbarium Specimens, Barry Kronenfeld, Andrew Weeks

Faculty Research and Creative Activity

Uncertainty fields have been suggested as an appropriate model for retrospective georeferencing of herbarium specimens. Previous work has focused only on automated data capture methods, but techniques for manual data specification may be able to harness human spatial cognition skills to quickly interpret complex spatial propositions. This paper develops a formal modeling language by which location uncertainty fields can be derived from manually sketched features. The language consists of low-level specification of critical probability isolines from which a surface can be uniquely derived, and high-level specification of features and predicates from which low-level isolines can be derived. In a case …

What Is The Taxonomic Identity Of Minnesota Wolves?, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The taxonomic identity of the historical and current wolf (Canis lupus L., 1758 or Canis lycaon Schreber, 1775 or their hybrids) population in Minnesota (MN) and the Great Lakes region has been, and continues to be, controversial. So too does its legal status under the U.S. Endangered Species Act. This review summarizes the morphological and genetic information about that population and concludes that historically the MN population consisted of a gray wolf (C. lupus) in the west and an eastern type (Canis lupus lycaon or C. lycaon) in the east with intergrades or hybrids between …

The inventory and condition survey of the Western Australian part of the Nullarbor region, undertaken by the Department of Agriculture and Food, Western Australia (DAFWA) between 2005 and 2007, describes and maps the natural resources of the region. This survey report provides a baseline record of the existence and condition of the area's natural resources, to assist with the planning and implementation of land management practices. The report identified and described the condition of soils, landforms, vegetation, habitat, ecosystems, and declared plants and animals. It also assessed the impact of pastoralism and made land management recommendations. The Nullarbor region has …

The Role Of Retrieval And Translocation In A Reintroduced Population Of Migratory Whooping Cranes, Sara E. Zimorski, Richard P. Urbanek

Proceedings of the North American Crane Workshop

Beginning in 2001, a reintroduction project was initiated using captive-reared whooping cranes (Grus americana) to establish a migratory flock in eastern North America. From May 2003 to August 2008, 23 of these birds were retrieved and translocated in 15 separate events. These individuals consisted of 14 cranes that had been led to Florida by ultralight aircraft on their first autumn migration (UL) and 9 cranes that had been directly released in autumn in Wisconsin (DAR). Of 104 (86 UL and 18 DAR) reintroduced individuals that eventually departed from their release location, 22% were later retrieved 1-3 times. Lake …

Home Range Size And Habitat Use Of Mississippi Sandhill Crane Colts, Scott G. Hereford, Tracy E. Grazia, Jereme N. Phillips, Glenn H. Olsen

Proceedings of the North American Crane Workshop

Recruitment in the endangered Mississippi sandhill crane (Grus canadensis pulla) is minimal, with the population of 110 sustained by an annual augmentation of captive-reared juveniles. Suitability of available habitat quality is likely involved in nesting success. Thousands of hectares of pine savanna were restored for crane use, but it is not clear how much was being used by crane families. We used 3-g subcutaneous transmitters to radio-tag 27 colts over 6 years from 1998 to 2002 and 2004 to determine home range and habitat use. Using a hand-held receiver, H-antenna and standard triangulation, location data were collected twice …
