Human-Carnivore Relations: Conflicts, Tolerance And Coexistence In The American West, Juan M. Requena-Mullor
Human-Carnivore Relations: Conflicts, Tolerance And Coexistence In The American West, Juan M. Requena-Mullor
Biology Faculty Publications and Presentations
Carnivore and humans live in proximity due to carnivore recovery efforts and ongoing human encroachment into carnivore habitats globally. The American West is a region that uniquely exemplifies these human-carnivore dynamics, however, it is unclear how the research community here integrates social and ecological factors to examine human-carnivore relations. Therefore, strategies promoting human-carnivore coexistence are urgently needed. We conducted a systematic review on human-carnivore relations in the American West covering studies between 2000 and 2018. We first characterized human-carnivore relations across states of the American West. Second, we analyzed similarities and dissimilarities across states in terms of coexistence, tolerance, number …
Payment For Ecosystem Services: Incentives To Support Environmental Quality & Farming In Vermont, Stephen Posner, Taylor Ricketts, Eric Roy
Payment For Ecosystem Services: Incentives To Support Environmental Quality & Farming In Vermont, Stephen Posner, Taylor Ricketts, Eric Roy
Reports and Policy Briefs
Environmental quality is an ongoing concern in the Lake Champlain Basin. Vermont farmers are in a unique position to manage land in a way that maintains and improves environmental quality. A payment for ecosystem services (PES) program for Vermont would both support the economic vi- ability of Vermont farms and incentivize farmers to improve water quality and soil health. How- ever, conceptual and practical implementation challenges remain.

The Midwestern U.S. landscape is one of the most highly altered and intensively managed ecosystems in the country. The predominant crops grown are maize (Zea mays L.) and soybean [Glycine max (L.) Merr]. They are typically grown as monocrops in a simple yearly rotation or with multiple years of maize (2 to 3) followed by a single year of soybean. This system is highly productive because the crops and management systems have been well adapted to the regional growing conditions through substantial public and private investment. Furthermore, markets and supporting infrastructure are highly developed for both crops. As maize and …

The Missing Angle: Ecosystem Consequences Of Phenological Mismatch, Karen H. Beard, Katharine C. Kelsey, A. Joshua Leffler, Jeffrey M. Welker
Ecology Center Publications
Climate change leads to unequal shifts in the phenology of interacting species, such as consumers and their resources, leading to potential phenological mismatches. While studies have investigated how phenological mismatch affects wild populations, we still lack studies and a framework for investigating how phenological mismatch affects ecosystems, particularly nutrient cycling.

Valuing The Economic Benefits Of Conservation Land In Downeast Maine, Lesley Lichko, Mindy Crandall, Tora Johnson, Adam Daigneault
Forest Resources Faculty Scholarship
This report uses an ecosystem services approach to calculate the economic value of conservation lands in Downeast Maine, an area composed of Hancock and Washington Counties. This region, roughly bordered by the Atlantic Ocean, the Penobscot River, and Canada, includes extensive coastline, thousands of acres of forestland, areas of agricultural land, mountains, lakes, rivers, and wetlands. The area is known for its recreational and aesthetic resources, and productive offshore areas. Employment centers range from the tourism-dominated area of Bar Harbor in Hancock County, adjacent to Acadia National Park, to the Baileyville tissue mill and Woodland pulp mill area in Washington …
Evaluating Oyster Aquaculture’S Cost-Effectiveness As A Nitrogen Removal Best Management Practice – A Case Study Of The Delaware Inland Bays, Jefferson F. Flood
Evaluating Oyster Aquaculture’S Cost-Effectiveness As A Nitrogen Removal Best Management Practice – A Case Study Of The Delaware Inland Bays, Jefferson F. Flood
Journal of Ocean and Coastal Economics
Disease and overfishing have led to a dramatic decline in wild populations and subsequent harvests of the eastern oyster Crassostrea virginica over the past few decades in Delaware and other states along the Atlantic Coast. However, in addition to their value as food to consumers, oysters, whether wild populations or cultured stocks, can provide ecosystem services such as nutrient removal, which may result in localized water quality improvements. Consequently, recent policies in Delaware have sought to establish and grow an oyster aquaculture industry. However, a key challenge to achieving efficient levels of industry growth and water quality improvements is that …

Enhancing floral resources is a widely accepted strategy for supporting wild bees and promoting crop pollination. Planning effective enhancements can be informed with pollination service models, but these models should capture the behavioural and spatial dynamics of service-providing organisms. Model predictions, and hence management recommendations, are likely to be sensitive to these dynamics. We used two established models of pollinator foraging to investigate whether habitat enhancement improves crop visitation; whether this effect is influenced by pollinator foraging distance and landscape pattern; and whether behavioural detail improves model predictions. The more detailed central place foraging model better predicted variation in bee …

Dramatic growth in herbicide-resistant (HR) weeds in the United States threatens farm profitability and may undercut environmentally beneficial farming practices. When HR weeds move across farm boundaries due to ecological processes or human action, a common pool resource challenge emerges, requiring farmer cooperation to manage such weeds effectively. We investigate the scope for cooperative management using responses to a national survey on HR weed issues to test a recursive model of three preconditions for collective action: (1) concern about HR weeds migrating from nearby lands; (2) communication with neighbors about HR weeds; and (3) belief that cooperation is necessary for …

Deltas and backwater‐affected bottomlands are forming along tributary and mainstem confluences in reservoirs worldwide. Emergence of prograding deltas, along with related upstream hydrogeomorphic changes to river bottomlands in the backwater fluctuation zones of reservoirs, signals the development of new and dynamic riparian and wetland habitats. This study was conducted along the regulated Missouri River, USA, to examine delta‐backwater formation and describe vegetation response to its development and dynamics. Our research focused specifically on the delta‐backwater forming at the confluence of the White River tributary and Lake Francis Case reservoir. Objectives of the research were to: (1) describe and analyze the …

Relationship Between Habitat And Barn Owl Prey Delivery Rate And Composition In A Napa Valley Vineyard Agroecosystem, Dane A. R. St. George
Relationship Between Habitat And Barn Owl Prey Delivery Rate And Composition In A Napa Valley Vineyard Agroecosystem, Dane A. R. St. George
Cal Poly Humboldt theses and projects
The provision of habitat for natural enemies of agricultural pests is common in integrated pest management approaches globally but has rarely been examined for vertebrate predators controlling vertebrate pests. To mitigate the economic and environmental costs of treating for rodent pests, winegrape producers in Napa Valley, California, have installed nest boxes to attract barn owls (Tyto alba) to their properties, but their effectiveness to control rodent pests in vineyards has not been thoroughly tested. A rigorous estimate of the number of rodents barn owls remove from the landscape is a necessary first step, and this study aimed to …
