A conceptual framework to evaluate human-wildlife interactions within coupled human and natural systems Ecology and Society
Morzillo, Anita T.; University of Connecticut; anita.morzillo@uconn.edu; de Beurs, Kirsten M.; University of Oklahoma; kdebeurs@ou.edu; Martin-Mikle, Chelsea J.; University of Oklahoma; chelseajane.martin@gmail.com.
Landscape characteristics affect human-wildlife interactions. However, there is a need to better understand mechanisms that drive those interactions, particularly feedbacks that exist between wildlife-related impacts, human reaction to and behavior as a result of those impacts, and how land use and landscape characteristics may influence those components within coupled human and natural systems. Current conceptual models of human-wildlife interactions often focus on species population size as the independent variable driving those interactions. Such an approach potentially overlooks important feedbacks among and drivers of human-wildlife interactions that result from mere wildlife presence versus absence. We describe an emerging conceptual framework...

A Real Options Approach to Forest-Management Decision Making to Protect Caribou under the Threat of Extinction Ecology and Society
Morgan, Don G.; British Columbia Ministry of Forests and Range; Don.Morgan@gov.bc.ca.
Uncertainty is a dominant feature of decision making in forestry and wildlife management. Aggravating this challenge is the irreversibility of some decisions, resulting in the loss of economic opportunities or the extirpation of wildlife populations. We adapted the real options approach from economic theory to develop a methodology to evaluate a resource management decision to stop timber harvesting when a woodland caribou (Rangifer tarandus caribou) population becomes threatened with extinction. In our study area of central Labrador, Canada, both caribou and timber harvesting are valued ecosystem services. By using a decision rule, which incorporates future developments, the real options approach provides a technique to incorporate ecological and social...

“Letting the leaders pass”: barriers to using traditional ecological knowledge in comanagement as the basis of formal hunting regulations Ecology and Society
Padilla, Elisabeth; Resilience and Adaptation Program, University of Alaska Fairbanks; erobins@alaska.edu; Kofinas, Gary P.; Department of Humans and Environment and Institute of Arctic Biology, University of Alaska Fairbanks; gary.kofinas@alaska.edu.
We studied a case of failure in applying traditional ecological knowledge (TEK) in comanagement as the basis for formal hunting regulations. We based the study on the Porcupine Caribou (Rangifer tarandus) Herd “let the leaders pass” policy, established for the Dempster Highway of the Western Canadian Arctic, and identified conditions creating barriers in the successful application of TEK through comanagement. Stated as propositions, identified barriers include: (1) the context-specific nature of TEK limits its application in resource management regulations; (2) changes in traditional authority systems, hunting technology, and the social organization of harvesting caribou affect the effectiveness of TEK approaches in a contemporary...

Applications of resilience theory in management of a moose–hunter system in Alaska Ecology and Society
Brown, Casey L; Biology and Wildlife Department, University of Alaska Fairbanks; Resilience and Adaptation Program, University of Alaska Fairbanks; clbrown12@alaska.edu; Kellie, Kalin A; Alaska Department of Fish and Game, Fairbanks;; Brinkman, Todd J; Biology and Wildlife Department, University of Alaska Fairbanks; Resilience and Adaptation Program, University of Alaska Fairbanks; tjbrinkman@alaska.edu; Kielland, Knut; Biology and Wildlife Department, University of Alaska Fairbanks; Resilience and Adaptation Program, University of Alaska Fairbanks;.
We investigated wildfire-related effects on a slow ecological variable, i.e., forage production, and fast social-ecological variables, i.e., seasonal harvest rates, hunter access, and forage offtake, in a moose–hunter system in interior Alaska. In a 1994 burn, average forage production increased slightly (5%) between 2007 and 2013; however, the proportional removal across all sites declined significantly (10%). This suggests that moose are not utilizing the burn as much as they have in the past and that, as the burn has aged, the apparent habitat quality has declined. Areas with a greater proportion of accessible burned area supported both high numbers of hunters and harvested moose. Our results suggest that evaluating ecological variables in...

Bioeconomic modeling of wetlands and waterfowl in Western Canada: Accounting for amenity values AgEcon
van Kooten, G. Cornelis; Withey, Patrick; Wong, Linda.
This study extends an original bioeconomic model of optimal duck harvest and wetland retention by bringing in amenity values related to the nonmarket (in situ) benefits of waterfowl plsi the ecosystem values of wetlands themselves. The model maximizes benefits to hunters as well as the amenity values of ducks and ecosystem benefits of wetlands, subject to the population dynamics. Results indicate that wetlands and duck harvests need to be increased relative to historical levels. Further, the socially optimal ratio of duck harvest to wetlands is larger than what has been observed historically. Including amenity values leads to a significant increase in the quantity of wetlands and duck harvests relative to models that focus only on hunting values.

Empowering Local People through Community-based Resource Monitoring: a Comparison of Brazil and Namibia Ecology and Society
Rostant, Luke; University of the West Indies; lrostant@gmail.com; Marinelli, Carlos Eduardo; Instituto Socioambiental; caemari@gmail.com.
Biological resource monitoring systems are implemented in many countries and often depend on the participation of local people. It has been suggested that these systems empower local participants while promoting conservation. We reviewed three wildlife monitoring systems in indigenous lands and sustainable development reserves in Brazilian Amazonia and one in Namibian Caprivi conservancies, analyzing the strategies adopted and conditions that facilitated local empowerment, as well as potential impacts on conservation. This provided insights into potential avenues to strengthen empowerment outcomes of monitoring systems in Latin America and Africa. We assessed four dimensions of empowerment at individual and community scales: psychological, social,...

Mamíferos encontrados ao Sul do Estado do Acre, Brasil. Infoteca-e
DRUMOND, P. M.; SILVA, F. P. C. da; ROSAS, G. K. C.; GAIA, C..
Entre os anos de 2004 e 2008, sete inventários de mamíferos foram realizados em quatro áreas sob manejo florestal madeireiro e não madeireiro localizadas ao sul do Estado do Acre. A partir de transectos lineares instalados nas áreas, foi possível identificar 32 espécies pertencentes às ordens Artiodactyla, Perissodactyla, Carnivora, Primates, Rodentia e Xenarthra, que incluíram as espécies ameaçadas de extinção, de distribuição geográfica restrita ou pouco conhecidas. Entre os animais observados destaca-se a predominância dos primatas nas quatro áreas estudadas. Nesse caso, especula-se sobre a possibilidade desse grupo taxonômico ser utilizado como bioindicador da qualidade ambiental das áreas de manejo florestal no Estado do Acre.

Managing Excessive Predation in a Predator-Prey Setting: The Case of Piping Plovers AgEcon
Melstrom, Richard T.; Horan, Richard D..
Ecosystems involve interspecies interactions that can be influenced by human interventions. Prior work shows interventions that ignore these interactions cause efficiency-reducing ecosystem externalities. We show inefficiencies may also be attributable to nature, via interspecies interactions generating excessive competition or predation. Ecosystem management therefore may involve correcting both ecological and economic inefficiencies. We explore ecosystem management to correct ecological inefficiencies from predation. The inefficiencies are shown to be akin to anthropogenic externalities arising when humans harvest resources under open access conditions, and so the solution is to “regulate” predators. Viewing the ecological inefficiencies in this...

Nudging Evolution? Ecology and Society
This Special Feature, “Nudging Evolution? Critical Exploration of the Potential and Limitations of the Concept of Institutional Fit for the Study and Adaptive Management of Social-Ecological Systems,” aims to contribute toward the development of social theory and social research methods for the study of social-ecological system dynamics. Our objective is to help strengthen the academic discourse concerning if, and if so, how, to what extent, and in what concrete ways the concept of institutional “fit” might play a role in helping to develop better understanding of the social components of interlinkages between the socioeconomic-cultural and ecological dynamics of social-ecological systems. Two clearly discernible...

Scenario planning during rapid ecological change: lessons and perspectives from workshops with southwest Yukon wildlife managers Ecology and Society
Beach, Dylan M.; School of Environment and Sustainability, University of Saskatchewan; dylanbeach@gmail.com; Clark, Douglas A.; School of Environment and Sustainability, University of Saskatchewan; d.clark@usask.ca.
Scenario planning has been increasingly advocated as a strategic planning tool for enabling natural resource managers to make decisions in the face of uncertainty and rapid change. However, few examples exist that discuss the technique’s application in that field. We used a scenario planning approach to develop wildlife management goals and evaluated participants’ perceptions of scenario planning as a goal development tool. Study participants emphasized the context-specificity of management goals, and that “no-regrets” management strategies might not be constructive. We found that scenario planning can help resource managers identify needs that have been overlooked but may become important in the future. Scenarios...

Setting population targets for mammals using body mass as a predictor of population persistence ArchiMer
Hilbers, Jelle P.; Santini, Luca; Visconti, Piero; Schipper, Aafke M.; Pinto, Cecilia; Rondinini, Carlo; Huijbregts, Mark A. J..
Conservation planning and biodiversity assessments need quantitative targets to optimize planning options and assess the adequacy of current species protection. However, targets aiming at persistence require population-specific data, which limits their use in favor of fixed and non-specific targets, likely leading to unequal distribution of conservation efforts among species. Here we propose a method to derive equitable population targets, which are quantitative targets of population size that ensure equal probabilities of persistence across a set of species, and can be easily inferred from species-specific traits. We applied population dynamics models across a range of life-history traits representative for mammals, and estimated minimum viable population...

The Effect of Climate Change on Wetlands and Waterfowl in Western Canada: Incorporating Cropping Decisions into a Bioeconomic Model AgEcon
Withey, Patrick; van Kooten, G. Cornelis.
We extend an earlier bioeconomic model of optimal duck harvest and wetland retention in the Prairie Pothole Region of Western Canada to include cropping decisions. Instead of a single state equation, the model has two state equations representing the population dynamics of ducks and the amount of wetlands. We use the model to estimate the impact of climate change on wetlands and waterfowl, including direct climate effects as well as land use change due to biofuel policies aimed at mitigating climate change. The model predicts that climate change will reduce wetlands by 47-56 percent from historic levels. Land use change is expected to reduce wetlands by 45 percent from historic levels, whereas direct climate effects will range from a reduction of 2-11...
