Potential For Climate Induced Methane Hydrate Dissociation, 2018 Pomona College
Potential For Climate Induced Methane Hydrate Dissociation, Graham Macwilliams
Pomona Senior Theses
Methane hydrates are frozen deposits of methane and water found in high pressure or low temperature sediments. When these deposits destabilize, large quantities of methane can be emitted into the atmosphere. This is significant to climate change because methane has 25 times more greenhouse gas potential than Carbon Dioxide. Worldwide, it is estimated there are between 2500 and 10000 gigatons of methane stored in hydrate deposits. This represents more carbon than all fossil fuels on Earth. It is estimated that between 200 and 2000 gigatons of methane are stored in hydrates in Arctic waters acutely vulnerable to greenhouse warming. Over ...
The North American Quails, Partridges, And Pheasants, 2017 University of Nebraska-Lincoln
The North American Quails, Partridges, And Pheasants, Paul A. Johnsgard
This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel’s, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are ...

Community Perceptions Of Grivet Monkey Crop Depredation In The Ethiopian Highlands: Implications For Primate Conservation, 2017 Department of Animal, Rangeland and Wildlife Science, Mekelle University, P.O. Box 231, Mekelle, Ethiopia
Community Perceptions Of Grivet Monkey Crop Depredation In The Ethiopian Highlands: Implications For Primate Conservation, Aschalew Alelign, Meheretu Yonas
Human–primate conflicts in Africa have been increasing due to increased human population growth and the resulting competition for forest resources. The Ethiopian Highlands in northern Ethiopia, home to the grivet monkey (Chlorocebus aethiops), once consisted of large forested areas. This region has been severely denuded and now exhibits only small forest patches remaining at sites with special cultural significance in the immediate vicinity of churches. These forest patches, surrounded by agricultural crops, provide refugia habitat for the grivet monkey. We randomly surveyed 50 villagers living near the Batiero Church Forest, a 45-ha forest patch located in northern Ethiopia, to ...

Processing Conservation Indicators With Open Source Tools: Lessons Learned From The Digital Observatory For Protected Areas, Lucy Bastin, Andrea Mandrici, Luca Battistella, Grégoire Dubois
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
The European Commission has a commitment to open data and the support of open source software and standards. We present lessons learnt while populating and supporting the web and map services that underly the Joint Research Centre's Digital Observatory for Protected Areas. Challenges include: large datasets with highly complex geometries; topological inconsistencies, compounded by reprojection for equal-area calculations; multiple different representations of the same geographical entities, for example coastlines; licensing requirement to continuously update indicators to respond to monthly changes in the authoritative data. In order to compute and publish an array of indicators, we used a range of ...
The Second Record Of A Relict Akrav Israchanani Levy, 2007 (Scorpiones: Akravidae) From Levana Cave, Israel, Victor Fet, Michael E. Soleglad, Sergei L. Zonstein, Israel Naaman, Shlomi Lubaton, Boaz Langford, Amos Frumkin
We report the remnants of five new scorpion specimens discovered dead in Levana Cave in Israel in December 2015. We confirm that they belong to the relict scorpion Akrav israchanani Levy, 2007 (Akravidae), famously described from the neighboring Ayyalon Cave, also from dead specimens. The details of morphology of the new specimens are given; they match completely the characters of A. israchanani redescribed by Fet, Soleglad & Zonstein (2011). This second record indicates a wider distribution of this unique cave scorpion, which, however, is extinct in both caves. There is still no evidence that live populations of this species exist.
Physiological Ecology Of Four Endemic Alabama Species And The Exotic Asiatic Weatherfish, Misgurnus Anguillicaudatus (Cantor, 1842), Lindsay M. White, Mark E. Meade, Benjamin A. Staton
Southeastern Fishes Council Proceedings
The occurrence of Asiatic Weatherfish, Misgurnus anguillicaudatus, in Alabama, a state known for its rich biodiversity, has generated concern among conservation managers. The current study used respirometry techniques to investigate the effects of increasing temperature on four native southeastern fishes (one cyprinid, two percids, and one elassomid) and the non-native M. anguillicaudatus. A minimum of five individuals of each species were used, and three experimental temperatures were chosen to represent spring and summer averages of northeast Alabama streams (15, 20, and 25°C). Overall, mean standard metabolic rates (SMRs) for M. anguillicaudatus were low (97.01, 127.75, and 158 ...
First Report Of A Population Of Western Blacknose Dace (Rhinichthys Obtusus) In The Brushy Creek System Of The Black Warrior River Drainage, Alabama, Eric Bauer, Malorie M. Hayes
Southeastern Fishes Council Proceedings
Alabama is home to the southernmost populations of Rhinichthys obtusus, the Western Blacknose Dace. Within Alabama, R. obtusus is found in the Tennessee, Coosa, and Black Warrior River basins, but its presence in the Black Warrior River drainage has been limited. Until now, R. obtusus in the Black Warrior drainage has only been reported as collections of 1 to 4 specimens at a time in the Sipsey Fork drainage. Herein, we report two novel occurrences of R. obtusus in the headwaters of the Brushy Creek system in the Black Warrior River drainage including a singleton and a large population. The ...
Effects Of A Prescribed Burn On The Adult Butterfly Assemblage Of A Coastal Grassland, 2017 College of Coastal Georgia
Effects Of A Prescribed Burn On The Adult Butterfly Assemblage Of A Coastal Grassland, J. Nicole Desha, Joseph Colbert, Kimberly M. Andrews, Scott Coleman, C. Tate Holbrook
Georgia Journal of Science
Coastal grasslands are globally threatened by development and natural succession. In the southeastern United States, these increasingly rare ecosystems are being managed using prescribed fire, but ecological responses to fire management are largely unknown, particularly among nontargeted species. We tested for short-term effects of controlled burning on the abundance and species richness of adult butterflies, which utilize coastal grasslands for nectaring resources and as migratory stopover sites. In February 2015, four plots of coastal grassland on Little St. Simons Island, GA were burned and paired with unburned (control) plots of equal size. Throughout the following summer-fall flight season, we conducted ...
European Starlings, 2017 USDA National Wildlife Research Center
European Starlings, H. Jeffrey Homan, Ron J. Johnson, James R. Thiele, George M. Linz
Wildlife Damage Management Technical Series
European starlings (Sturnus vulgaris, Figure 1) are an invasive species in the United States. The first recorded release of the birds was in 1890 in New York City’s Central Park. Because starlings easily adapt to a variety of habitats, nest sites and food sources, the birds spread quickly across the country. Today, there are about 150 million starlings in North America. Conflicts between people and starlings occur mostly in agricultural settings. Conflicts can occur during winter in urban and suburban environments, especially in business districts.
Starlings damage apples, blueberries, cherries, figs, grapes, peaches, and strawberries. Besides causing direct losses ...
Walking As Ontological Shifter: Thoughts In The Key Of Life, 2017 The Graduate Center, City University of New York
Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro
All Graduate Works by Year: Dissertations, Theses, and Capstone Projects
With walking as ontological shifter I pursue an alternative to the dominant modernist episteme that offers either/or onto-epistemologies of opposition and their reifying engagements. I propose this type of walking is an intentional turning towards a set of radical positions that, as integrative aesthetic and therapeutic practice, brings multiplicity and synchronicity to experience and being in an expanded sociality. This practice facilitates the conditions of possibility for recurring points of contact between the interiority perceived as ‘body’ and the exteriority perceived as ‘world.’ While making evident the self’s at once incoherence with it-self, it opens to a space ...
The Scorpion Fauna Of Mona Island, Puerto Rico (Scorpiones: Buthidae, Scorpionidae), 2017 Museo de Historia Natural “Tomás Romay”
The Scorpion Fauna Of Mona Island, Puerto Rico (Scorpiones: Buthidae, Scorpionidae), Rolando Teruel, Mel J. Rivera, Alejandro J. Sánchez
The scorpion fauna of the small Mona Island (= Isla de Mona), located roughly midway between Hispaniola and Puerto Rico and administratively belonging to the latter, is herein revised. Three species are confirmed to occur: the buthids Centruroides bani Armas et Marcano Fondeur, 1987 and Heteroctenus abudi (Armas et Marcano Fondeur, 1987), plus the diplocentrine scorpionid Cazierius garridoi Armas, 2005. The previously recorded Heteronebo sp. is reexamined and deemed a mislabeled specimen of Heteronebo portoricensis Francke, 1978 from adjacent Puerto Rico. Also, Centruroides mariaorum Santiago-Blay, 2009 is demonstrated to be a junior synonym of C. bani (implying the first demonstrable records ...

Hemiscorpius Shahii Sp. N. From Iran (Scorpiones: Hemiscorpiidae), 2017 Razi Vaccine and Serum Research Institute,
Hemiscorpius Shahii Sp. N. From Iran (Scorpiones: Hemiscorpiidae), František Kovařík, Shahrokh Navidpour, Michael E. Soleglad
Hemiscorpius shahii sp. n. from Iran, Hormozgan Province, is described and compared with other species of Hemiscorpius genus. The new species is characterized mainly by total length of 84 (female) to 110.7 (male) mm and unique trichobothrial pattern of pedipalp patella. The number of external trichobothria on patella is 17–18 (5 eb, 4 esb, 2–3 em, 3 est, 3 et); the number of ventral trichobothria on patella is 14–16. This distinguishes H. shahii sp. n. from all other species of genus Hemiscorpius, which have 3 or 10–12 ventral trichobothria on patella, one or two trichobothria ...
An Erythristic Morph Of Red-Backed Salamander (Plethodon Cinereus) Collected In Virginia, 2017 East Tennessee State University
An Erythristic Morph Of Red-Backed Salamander (Plethodon Cinereus) Collected In Virginia, Trevor L. Chapman, Brian G. Gall, Kari L. Spivey
Virginia Journal of Science
Eight different color polymorphisms of the Red-backed Salamander (Plethodon cinereus) have been described throughout its range. Among them, the erythristic phenotype is a mimetic morph with coloration patterns similar to that of toxic Eastern Newt efts (Notophthalmus viridescens). We describe an erythristic morph of P. cinereus collected at Mountain Lake Biological Station, Virginia. To our knowledge, there are no prior published records of this morph in Virginia.
Herons And Egrets, 2017 USDA-APHIS-Wildlife Services
Herons And Egrets, Michael D. Hoy
Wildlife Damage Management Technical Series
Landscapes -- Herons and egrets commonly cause damage at aquaculture facilities and recreational fishing waters where fish are held at high densities. In one study, on average wading birds consumed from 4 to 24 golden shiners per day at minnow production facilities in Arkansas. Great blue herons and great egrets commonly feed at catfish production facilities in Mississippi. The tendency for herons and egrets to congregate in large feeding flocks often leads to extensive loss of fish at aquaculture facilities. Fish-eating birds also can have an impact on intensively managed sport fisheries. Damage occurs when herons and egrets feed ...
Large Marine Protected Areas Represent Biodiversity Now And Under Climate Change, 2017 Old Dominion University
Large Marine Protected Areas Represent Biodiversity Now And Under Climate Change, T. E. Davies, S. M. Maxwell, K. Kaschner, C. Garilao, N. C. Ban
Biological Sciences Faculty Publications
Large marine protected areas (>30,000 km2) have a high profile in marine conservation, yet their contribution to conservation is contested. Assessing the overlap of large marine protected areas with 14,172 species, we found large marine protected areas cover 4.4% of the ocean and at least some portion of the range of 83.3% of the species assessed. Of all species within large marine protected areas, 26.9% had at least 10% of their range represented, and this was projected to increase to 40.1% in 2100. Cumulative impacts were significantly higher within large marine protected areas ...
