Responses Of Pond-Breeding Amphibians To Wildfire: Short-Term Patterns In Occupancy And Colonization, Blake R. Hossack, Paul Stephen Corn

United States Geological Survey: Staff Publications

Wildland fires are expected to become more frequent and severe in many ecosystems, potentially posing a threat to many sensitive species. We evaluated the effects of a large, stand-replacement wildfire on three species of pond-breeding amphibians by estimating changes in occupancy of breeding sites during the three years before and after the fire burned 42 of 83 previously surveyed wetlands. Annual occupancy and colonization for each species was estimated using recently developed models that incorporate detection probabilities to provide unbiased parameter estimates. We did not find negative effects of the fire on the occupancy or colonization rates of the long-toed …

Ethnoprimatology: Toward Reconciliation Of Biological And Cultural Anthropology, Erin P. Riley

Ecological and Environmental Anthropology (University of Georgia)

One of the hallmarks of the discipline of anthropology is its holistic approach to the study of what it means to be human. A perennial challenge to the discipline, however, is the question of whether biological and cultural anthropology can truly coexist given their traditionally disparate epistemologies and methodologies. In this paper, I argue that the emerging field of ethnoprimatology, which focuses on the ecological and cultural interconnections between human and nonhuman primates, has real potential to bridge these two subfields. I support my argument by discussing the theoretical rationale of an ethnoprimatological approach with regard to the notion of …

Human And Non-Human Primate Co-Existence In The Neotropics: A Preliminary View Of Some Agricultural Practices As A Complement For Primate Conservation, Alejandro Estrada

Ecological and Environmental Anthropology (University of Georgia)

In this paper I address the general perception that agricultural activities are the principal threat to primate biodiversity in the tropics and argue that in Neotropical landscapes some agricultural practices may favor primate population persistence, and that this situation merits attention and investigation. To explore these issues, I examined three interrelated pressures upon tropical forests for the Mesoamerican and Amazon basin regions: human population growth trends, levels of poverty and human development and deforestation rates. I also present relevant results of recent surveys completed on the presence and activities of primate populations in agroecosystems in several landscapes in Mesoamerica. I …

Human Dimensions Of Northern Muriqui Conservation Efforts, Karen B. Strier, Jean P. Boubli, Francisco B. Pontual, Sergio L. Mendes

Ecological and Environmental Anthropology (University of Georgia)

The northern muriqui (Brachyteles hypoxanthus) is endemic to Brazil’s Atlantic Forest, and it ranks among the most critically endangered primates in the world. Roughly 25% of the species is found in the 957 ha forest at the Estação Biológica de Caratinga/RPPN-Feliciano Miguel Abdala, in Minas Gerais, Brazil. The long-term research and conservation efforts at this site have received considerable attention, and public awareness and educational campaigns about northern muriquis have been highly effective. Nonetheless, very little about the human dimensions of these efforts have been explicitly described. In this paper, we focus on three distinct, but interconnected dimensions: …

Policy Tools For Smart Growth In New England, New England Environmental Finance Center

Smart Growth

Across New England communities have been experiencing a rapid outward surge of development away from our community and downtown centers. Effects of sprawl include a loss of wildlife habitat, farm and timber lands; increased costs of community services and higher taxes; auto-dependency, longer commutes, and increased congestion; increases in air and water pollution; a sedentary lifestyle and increased obesity; and losses to one’s sense of place and social ties.

State-level responses to sprawl have surfaced throughout New England in recent years. This report describes 11 examples of these responses, representing all six New England states and a diversity of recent …

Realizing The Potential Of Family Forests: Tools To Facilitate Habitat Conservation, Drue Deberry, Julie H. Moore

11th Triennial National Wildlife and Fisheries Extension Specialists Conference (2006)

The management of family-owned forests is discussed in light of conservation issues and development pressures. Safe Harbor Agreements and Candidate Conservation Agreements with Assurances are voluntary tools that can be used to protect conservation values, particularly habitat for threatened or endangered species. A case history of forest management practices to sustain the gopher tortoise in the Southeast is given.

Sage-Grouse Restoration Project: Evaluating The Effects Of The Farm Bill Conservation Practices On Sage-Grouse, Terry A. Messmer

11th Triennial National Wildlife and Fisheries Extension Specialists Conference (2006)

The Office of Management and Budget is demanding increased accountability of funds used to implement conservation practices and strategies. Although current Farm Bill policy provides priority funding for projects that are designed to enhance species conservation, it does not allocate funds to conduct the evaluations needed to document the effect of conservation practices on wildlife. The Sage-Grouse Restoration Project (SGRP) is a cooperative agreement with the Natural Resource Conservation Service (NRCS), designed specifically to facilitate evaluations to determine the effect of conservation practices and technologies implemented under the 2002 Farm Bill on restoring or enhancing sage-grouse habitat on private lands. …

Environmental Rearing Conditions Produce Forebrain Differences In Wild Chinook Salmon Oncorhynchus Tshawytscha, R. L. Kihslinger, Sean C. Lema, G. A. Nevitt

Biological Sciences

Recent studies suggest that hatchery-reared fish can have smaller brain-to-body size ratios than wild fish. It is unclear, however, whether these differences are due to artificial selection or instead reflect differences in rearing environment during development. Here we explore how rearing conditions influence the development of two forebrain structures, the olfactory bulb and the telencephalon, in juvenile Chinook salmon (Oncorhynchus tshawytscha) spawned from wild-caught adults. First, we compared the sizes of the olfactory bulb and telencephalon between salmon reared in a wild stream vs. a conventional hatchery. We next compared the sizes of forebrain structures between fish reared …

Liberty Of Ecological Conscience, Aaron Lercher

Faculty Publications

Our concern for nonhuman nature can be justified in terms of a human right to liberty of ecological conscience. This right is analogous to the right to religious liberty, and is equally worthy of recognition as that fundamental liberty. The liberty of ecological conscience, like religious liberty, is a negative right against interference. Each ecological conscience supports a claim to protection of the parts of nonhuman nature that are current or potential sites of its active pursuit of natural value. If we acknowledge the fallibility of each conscience in its pursuit of genuine natural value, a policy of indefinitely extensive …

Tropic And East Fork Irrigation Company, Tropic Ditch Replacement Project, Environmental Assessment, Bureau Of Reclamation, Provo Area Office

All U.S. Government Documents (Utah Regional Depository)

The purpose of this project is to reduce the amount of salt entering the Paria River and ultimately the Colorado River. One way to reduce the amount of salt reaching the Colorado River is to eliminate seepage from the historic Tropic Ditch. The Bureau of Reclamation, Provo Area Office has proposed funding for the project under the Colorado River Salinity Control Program. In addition to reducing the amount of salt loading, the project would also conserve water lost to evaporation and seepage.

The purpose of this Environmental Assessment (EA) is to analyze the potential environmental consequences of the proposed construction …

Testing An Ecophysiological Mechanism Of Morphological Plasticity In Pupfish And Its Relevance To Conservation Efforts For Endangered Devils Hole Pupfish, Sean C. Lema, Gabrielle A. Nevitt

Biological Sciences

Imperiled species that have been translocated or established in captivity can show rapid alterations in morphology and behavior, but the proximate mechanisms of such phenotypic changes are rarely known. Devils Hole pupfish (Cyprinodon diabolis) are endemic to a single desert pool and are characterized by a small body, large head and eyes, and lack of pelvic fins. To lessen the risk of extinction, additional populations of C. diabolis were established in artificial refuges. Yet, pupfish in these refuges rapidly shifted to a larger body, smaller head and eyes, and greater body depth. Here we examined how food availability …

Anadromous Rainbow Smelt And Tomcod In Connecticut: Assessment Of Populations, Conservation Status, And Need For Restoration Plan, Heather A. Fried, Eric T. Schultz

EEB Articles

(beginning of rainbow smelt executive summary)

Evidence indicates that anadromous rainbow smelt (Osmerus mordax) populations in Connecticut and elsewhere in the northeast United States have severely declined. Several sampling programs have documented declines in Connecticut’s smelt populations over the last three decades (Marcy 1976a, Marcy 1976b, Millstone Environmental Laboratory 2005). Similar declines have also been documented in the Hudson River (ASA Analysis & Communication 2005) and in Massachusetts (personal communication, Brad Chase, MA Division of Marine Fisheries 2004). Recreational and commercial fisheries in the region for this species have virtually ceased (Blake and Smith 1984). The Connecticut Fish Advisory Committee …

2005 Nutrient And Sediment Monitoring Report Ballard Creek Near Arkansas/Oklahoma Line, Marc Nelson, L. Wade Cash, Keith Trost, Jennifer Purtle, Marty Matlock

Technical Reports

The Illinois River Basin has experienced water quality impairment from non-point source pollution for many years. This fact was well documented in the State of Arkansas' Water Quality Assessment report, the Soil Conservation Service River Basin Study, and several University of Arkansas studies. Thirty-seven sub-watersheds have been identified by the SCS in the Arkansas portion of the Illinois River basin. In the Arkansas portion of the Basin, the Illinois River, Evansville Creek, Baron Fork, Cincinnati Creek, Muddy Fork, Moores Creek, Clear Creek, Osage Creek and Flint Creek were all classified as not supporting their designated use as primary contact recreation …

The Changing Face Of Conservation: Commodification, Privatisation And The Free Market, Sharon Beder

Faculty of Arts - Papers (Archive)

Environmentalists in the late 1960s and 1970s argued that the exponential growth of populations and industrial activity could not be sustained without seriously depleting the planet’s resources and overloading the planet’s ability to deal with pollution and waste materials. They argued that new technologies and industrial products, such as pesticides and plastics, also threatened the environment. Following the protest mood of the times, they did not hesitate to blame industry, western culture, economic growth and technology for environmental problems. They questioned western paradigms of development and industrialisation, and criticising the inequitable distribution of wealth and resource use.

Amherst Ma: A New Village Plan For Atkins Corner, Maggie Jones, Richard Barringer

Planning

The case study describes a successful smart growth initiative in the town of Amherst, Massachusetts, at an intersection known as Atkins Corner. The initiative grew from two motivating factors: the necessity of realigning Route 116, a major north-to-south artery through the town, to decrease traffic accidents at the intersection and improve pedestrian safety; and a desire on the part of Hampshire College and the Town to create a village center at the intersection. Through a consensus-building process involving key town officials, Hampshire College, neighbors, and the design firm of Dodson Associates, agreement on the project was reached with local stakeholders …

Coastal Aquaculture And Conservation Can Work Together, Tim Dempster, Pablo Sanchez-Jerez, Fernando Tuya, Damian Fernandez-Jover, Just Bayle-Sempere, Arturo Boyra, Ricardo Haroun

Research outputs pre 2011

Current fishing practices are regarded as unsustainable (Pauly et al. 2002), yet our appetite for seafood grows. To meet the growing gap, there are increasing calls for mankind to tame the oceans through aquaculture (Marra 2005). Close to the coast, rapid expansion of marine aquaculture is underway throughout the world. Sea cages enclose 2.5 million tons of fish, while 12 million tons of mussels, oysters and clams hang from floating ropes or grow on racks or trays (FAO 2004). Aquaculture structures are now ubiquitous to many coastlines. As the expansion continues, how can we best manage the interaction between natural …

Movement Of Cicindela Hirticollis Say Larvae In Response To Moisture And Flooding, Mathew L. Brust, William Wyatt Hoback, Kerri Farnsworth Skinner, Charles Barry Knisley

Department of Entomology: Faculty Publications

The larvae of the tiger beetle, Cicindela hirticollis Say, inhabit sandy shoreline areas that flood periodically. This species has declined over much of its range and at least one subspecies is near extinction, possibly as a result of human alteration of waterways. In addition to physiological tolerance for anoxia, the larvae have physical and behavioral adaptations to avoid drowning. We hypothesized that C. hirticollis larvae would exhibit behavioral responses to soil moisture change and flooding because, unlike most other tiger beetles, they frequently relocate their burrows. Our laboratory studies demonstrated that larvae select surface soil moisture levels of 7–50% saturation …

Conservation Of The Pho Regulon In Pseudomonas Fluorescens Pf0-1, Russell D. Monds, Peter D. Newell, Julia A. Schwartzman, George A. O'Toole

Dartmouth Scholarship

The Pho regulon integrates the sensing of environmental inorganic phosphate (Pi) availability with coregulation of gene expression, mediating an adaptive response to Pi limitation. Many aspects of the Pho regulon have been addressed in studies of Escherichia coli; however, it is unclear how transferable this knowledge is to other bacterial systems. Here, we report work to discern the conservation of the Pho regulon in Pseudomonas fluorescens Pf0-1. We demonstrate by mutational studies that PhoB/PhoR and the Pst system have conserved functions in the regulation of Pi-induced phosphatase activities, as well as expression of other Pi-regulated genes. A genetic screen was …

A Stackelberg Game Model Of Trade In Renewable Resources With Competitive Sellers, Amitrajeet A. Batabyal, Hamid Beladi

Articles

We model international trade in renewable resources between a single buyer and competitive sellers as a Stackelberg differential game. The buyer uses unit and ad valorem tariffs to indirectly encourage conservation of the renewable resource under study. First, we show that the efficacy of these trade policy instruments in promoting conservation depends fundamentally on whether harvesting costs are stock dependent or independent. When harvesting costs are stock independent, the optimal open loop tariffs are dynamically consistent. In contrast, when harvesting costs are stock dependent, the optimal open loop tariffs are dynamically inconsistent. Second, we point out that whether the terminal …

Assessment Of Anadromous Alewife And Blueback Herring Populations In Connecticut Coastal Streams And Connecticut River Tributaries, Justin P. Davis, Eric T. Schultz

EEB Articles

Alewife (Alosa pseudoharengus) and blueback herring (A. aestivalis) occur in anadromous populations that have a largely overlapping distribution from Florida to Newfoundland (Loesch 1987). Anadromous populations of these species are commonly collectively referred to as “river herring”. Adults inhabit coastal shelf waters until sexual maturity is reached at age 3-5 (Neves 1981). Sexually mature individuals make spawning migrations, commonly referred to as “runs”, into freshwater systems during spring months (Loesch 1987). Spawners can survive and return to spawn in subsequent years (Mullen et al. 1986). Juveniles reside in freshwater for 3-7 months, at which time they undertake a gradual migration …

A Switch From Polyandry To Serial Monogamy: Results From A Three Year Tagging Study Of Horseshoe Crabs In Long Island Sound, Jennifer Mattei Ph.D., Paul Goodell, Christine Depierro, Meghann Burke

Biology Faculty Publications

Part of an ongoing population study of the North American Horseshoe Crab, Limulus polyphemus, in Long Island Sound was completed during the 2003 – 2005 spawning seasons at Milford Point, in Milford, CT. Horseshoe crabs range more widely throughout Long Island Sound than expected and exhibit weak site fidelity. Animals originally tagged in Milford were found as far west as Stamford and as far east as Clinton, CT. during the 3 year study. Out of 522 female horseshoe crabs tagged in 2004 only 4 came back to spawn again at Milford Pt. in 2005. The sex ratios of tagged and …
