The Price Of Snow: Albedo Valuation And A Case Study For Forest Management, David A. Lutz, Richard B. Howarth
The Price Of Snow: Albedo Valuation And A Case Study For Forest Management, David A. Lutz, Richard B. Howarth
Dartmouth Scholarship
Several climate frameworks have included the role of carbon storage in natural landscapes as a potential mechanism for climate change mitigation. This has resulted in an incentive to grow and maintain intact long-lived forest ecosystems. However, recent research has suggested that the influence of albedo-related radiative forcing can impart equal and in some cases greater magnitudes of climate mitigation compared to carbon storage in forests where snowfall is common and biomass is slow-growing. While several methodologies exist for relating albedo-associated radiative forcing to carbon storage for the analysis of the tradeoffs of these ecosystem services, they are varied, and they …
A Basic Guide For Empirical Environmental Social Science, Michael Cox
A Basic Guide For Empirical Environmental Social Science, Michael Cox
Dartmouth Scholarship
In this paper, I address a gap in the literature on environmental social science by providing a basic rubric for the conduct of empirical research in this interdisciplinary field. Current literature displays a healthy diversity of methods and techniques, but this has also been accompanied by a lack of consistency in the way in which research in this area is done. In part this can be seen as resulting from a lack in supporting texts that would provide a basis for this consistency. Although relevant methods texts do exist, these are not written with this type of research explicitly in …
Unintended Outcomes Of Farmers' Adaptation To Climate Variability: Deforestation And Conservation In Calakmul And Maya Biosphere Reserves, Claudia Rodriguez-Solorzano
Unintended Outcomes Of Farmers' Adaptation To Climate Variability: Deforestation And Conservation In Calakmul And Maya Biosphere Reserves, Claudia Rodriguez-Solorzano
Dartmouth Scholarship
Minimizing the impact of climate change on farmer livelihoods is crucial, but adaptation efforts may have unintended consequences for ecosystems, with potential impacts on farmers’ welfare. Unintended outcomes of climate adaptation strategies have been widely discussed, however, empirical exploration has been neglected. Grounded in scholarship on climate adaptation, environmental governance, social–ecological systems, and land-use change, this paper studies whether farmers’ climate adaptation contributes to deforestation or forest conservation. The paper draws on interviews with 353 farmers from 46 communities in Calakmul Biosphere Reserve in Mexico and Maya Biosphere Reserve in Guatemala. Farmers in the area of study have implemented adaptation …
Changes In Nitrogen Cycling During The Past Century In A Northern Hardwood Forest, Kendra K. Mclauchlan, Joseph M. Craine, W. Wyatt Oswald, Peter R. Leavitt, Gene E. Likens
Changes In Nitrogen Cycling During The Past Century In A Northern Hardwood Forest, Kendra K. Mclauchlan, Joseph M. Craine, W. Wyatt Oswald, Peter R. Leavitt, Gene E. Likens
Dartmouth Scholarship
Nitrogen (N) availability, defined here as the supply of N to terrestrial plants and soil microorganisms relative to their N demands, limits the productivity of many temperate zone forests and in part determines ecosystem carbon (C) content. Despite multidecadal monitoring of N in streams, the long-term record of N availability in forests of the northeastern United States is largely unknown. Therefore, although these forests have been receiving anthropogenic N deposition for the past few decades, it is still uncertain whether terrestrial N availability has changed during this time and, subsequently, whether forest ecosystems have responded to increased N deposition. Here, …
Stage-Specific And Interactive Effects Of Sedimentation And Trout On A Headwater Stream Salamander, Winsor H. Lowe, Keith H. Nislow, Douglas T. Bolger
Stage-Specific And Interactive Effects Of Sedimentation And Trout On A Headwater Stream Salamander, Winsor H. Lowe, Keith H. Nislow, Douglas T. Bolger
Dartmouth Scholarship
In species with complex life cycles, stage-specific effects of environmental conditions combine with factors regulating stage-specific recruitment to determine population-level response to habitat disturbance. The abundance of the stream salamander Gyrinophilus porphyriticus(Plethodontidae) is negatively related to both logging-associated sedimentation and brook trout (Salvelinus fontinalis) in headwater streams throughout New Hampshire, USA. To understand the mechanisms underlying these patterns, we investigated stage-specific and interactive effects of sedimentation and brook trout on G. porphyriticus. We conducted quantitative surveys of salamanders, brook trout, and substrate embeddedness in 15 first-order streams and used a controlled experiment to test the direct and interactive effects of …
Africa's Conservation For Development, Norman Miller, Rodger Yeager
Africa's Conservation For Development, Norman Miller, Rodger Yeager
Dartmouth Scholarship
Africa's modern dilemma is a "floor of life" issue. Resource loss, environmental degredation, and overpopulation have reduced many people to the lowest subsistence levels in living memory. By all accounts a biologically diverse wonderland, Africa is quite literally the last place on earth for many plant and animal species. Yet the basis of human and nonhuman survival has become threatened in many areas because of soil and water depletion, deforestation, and desertification. Human mistakes are invariably cited as among the basic causes of these tragedies.
