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.

A Unique Population Of Cave Bears (Carnivora: Ursidae) From The Middle Pleistocene Of Kents Cavern, England, Based On Dental Morphometrics, Donald A. Mcfarlane, Martin Sabol, Joyce Lundberg

WM Keck Science Faculty Papers

The ‘breccia’ stratum from Kents (we follow local tradition in using the form ‘Kents’, without an apostrophe) Cavern, England, has been well known for its rich yield of cave-bear material since excavations began in the mid-19th century. Recent work has established that the bears are of latest MIS 12 or earliest MIS 11 age. A life table based on a collection of 67 molariform teeth is consistent with the use of the cave as a hibernaculum. Univariate and morphological assessment of the teeth shows an unusual range of primitive and more derived characters. Multivariate morphometric analysis of cave-bear teeth from …

Estimates Of Toad Headed Agama Density In Three Steppe Habitats Of Mongolia, James Murdoch, Buyandelger Suuri, Richard P. Reading

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

The toad headed agama (Phrynocephalus versicolor) ranges across the arid steppe regions of southern and western Mongolia and represents one of the most common reptiles in the country. However, few details of the species’ population characteristics exist, which may be important for evaluating population trends and assessing its conservation status. We estimated toad headed agama density in Ikh Nart Nature Reserve, Mongolia based on surveys conducted in the summers (June-September) of 2005, 2006, 2008, and 2009. We conducted surveys in three steppe habitats including tall grassland (n = 7), shrub-steppe (n = 7), and semi-shrub steppe …

During 1988-2004 Russian and German biologists carried out a research of biodiversity of the mountain taiga within the territory of State Nature Reserve “Azas” (Republic of Tyva/Russia). Along with executing the main task – studying and development of an aboriginal population of Tuvinian beavers Castor fiber tuvinicus – materials on the fauna of small mammals of the Todzha kettle were collected. On the basis of samples (about 550 collected micromammals) information on the occurrence, reproduction and morphometric characteristics of four species of Insectivora, six species of Chiroptera and eleven species of small Rodentia inhabiting the territory of the reserve “Azas” …

Temporal Dynamics Of Group Size And Sexual Segregation In Ibex, N. J. Singh, S. Amgalanbaatar, Richard P. Reading

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Group size is an important variable describing behavioral ecology of animals. A variety of factors such as habitat characteristics, life history, spatio-temporal resource dynamics, population density, predation risk, competition with kin, and social learning often determine group size in large mammals. We studied temporal dynamics of group size in Siberian ibex (Capra sibirica) in a protected area in Mongolia. We measured monthly and yearly variations in typical group size and used the sexual segregation and aggregation statistic to assess sexual segregation. Ibex formed the largest groups in November and smallest groups in July. However, group sizes did not …

Characteristics Of Mongolian Wild Ass Hooves (Equus Hemionus Hemionus), Jan Gahsche, Michael Stubbe, Matthias Oppermann, N. Batsajchan, Annegret Stubbe

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Measurements of hoof angles, hoof length, toe length, etc., and non-metrical hoof characters of Mongolian Wild Ass carcasses collected in in the South Gobi and in Bordzongijn-Gobi desert are presented. Khulan hooves are flat, wide and look big in relation to the animal’s dimensions. Remarkably is the wide variability in size, angles, in non metric characteristics like shape, color and the occurrence of particularly prolonged hoof wall and flaring walls. For example, toe angles are 52° for front and 54° for hind hooves on average. This measures and the suggested graphical model of the „ideal hoof shape“ can assist to …

Water Use Of Asiatic Wild Asses In The Mongolian Gobi, Petra Kaczensky, V. Dresley, D. Vetter, H. Otgonbayar, C. Walzer

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Water is a key resource for most large bodied mammals in the world’s arid areas. With the growing human population, access to water for wildlife often becomes compromised. Equids are typical inhabitants of semi-arid to arid rangelands and need regular access to fresh water. However, their water needs are difficult to study under free-ranging conditions. In this study we investigated Asiatic wild ass (Equus hemionus) use of permanent water points in the Great Gobi B Strictly Protected Area (SPA) in south-western Mongolia. We combined observational data from one specific water point with high frequency GPS location data from …

The Use Of High Frequency Gps Data To Classify Main Behavioural Categories In A Przewalski’S Horse In The Mongolian Gobi, Petra Kaczensky, Klaus Huber

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

Behavioral observations of free ranging animals can provide important insight into many aspects of their biology but are not without problems. The recent development of GPS technology allows to remotely collect high precision location data at fixed intervals. We tested whether it is possible to classify the behavior of a Przewalski’s horse in the Mongolian Gobi into Resting, Grazing and Moving based on GPS locations collected at 15 minute intervals by comparing GPS data with direct observations. Although behavioral categories lasting for 15 minutes could by fairly reliably separated based on the distances covered between successive fixes, almost half the …

The Institute For Raptor Studies Expeditions In Mongolia, 1994-2000, David H. Ellis

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

In 1994, 1995, 1997, 1998, and 2000, I led small teams of biologists across Mongolia in search of Saker falcon (Falco cherrug Gray) and golden eagle (Aquila chrysaetos) eyries. We also counted raptors along our march route during the first three years. These expeditions documented: (1) occupancy and productivity rates, and described eyrie sites, for Saker falcons (150 territories, 182 eyries) and golden eagles (27 known breeding territories), (2) mortality of Sakers and ipland buzzards (Buteo hemilasius) due to entanglement with trash in nests and loss of golden eagle eggs due to concealment by trash in nests, …

Student Works (2010-2019)

A study had been carried out on Paya Indah Wetlands’ water quality from December 2006 to February 2007. This was to determine the status of water quality. From the analysis on Water Quality Index (WQI) at 15 sampling stations, it was observed that WQI of Paya Indah at most stations were within polluted range. From the comparative study made on WQI at major lakes and canals between year 1996 and 2006/2007, it was observed that Canal C2 and Canal C4 show slight improvement (48.7 – 50.0 and 41.5 – 59.2 respectively). However, major lakes of Paya Indah shows decrease of …

Native Species Interactions With Red Brome: Suggestions For Burn-Area Revegetation, Scott R. Abella

Public Policy and Leadership Faculty Research

In deserts, native perennial plants often actually facilitate the establishment of exotic annual grasses. One of our focal areas of research is to identify native species for use in revegetation projects that reduce the establishment of exotic annual grasses, or at least do not strongly facilitate exotic species establishment. An initial research effort involving a competition experiment of red brome with native species and a correlational field study of brome distribution among native perennial plants is in press with the journal Invasive Plant Science and Management.

Trying To Beat The Brome: Understanding Establishment Thresholds And Choosing Competitive Native Species At Parashant National Monument, Scott R. Abella, E. Cayenne Engel

Public Policy and Leadership Faculty Research

Desert fires fueled by exotic grasses like the omnipresent red brome (Bromus rubens) can be intense and cause widespread mortality of native vegetation. Native desert scrub communities such as those dominated by blackbrush (Coleogyne ramosissima) do not readily reestablish after fire (Abella 2009) and may even become more abundant in the post-burn landscape initiating a fire cycle that occurs at a greater frequency than the recovery time of the long-lived desert perennial community.
