Structure, function and dynamics of transitions between plant communities, Descrição: Boundary structure affects flows of energy, material and organisms across transitions between adjacent ecosystems on the landscape. Differences in the characteristics of edges including structue may depend on factors such as forest type or the type and age of edge. My research program includes studies on the structure, dynamics and function of natural forest edges. Research will be conducted near Churchill, Manitoba and in Cape Breton, Nova Scotia. My short term projects include a comparison of forest edges of different structure in different types of forest and the establishment of permanent plots to investigate temporal dynamics of boundaries. The proposed research will provide insight into how boundary structure affects patterns and processes at forest edges and initiate important long-term research on the temporal dynamics of natural boundaries. Results from these studies will contribute towards my long-term goal of developing an analytical model that predicts the effects of stand and landscape-level charactistics on boundary structure and function. An understanding of the landscape patterns and processes is important as a context within which to assess the impact of forest management practices, hydroelectric development and climate change. This knowledge will greatly advance the field of landscape ecology which currently lacks specific information on natural edges. Canada will benefit from a greater understanding of landscape patterns and processes in the boreal forest, especially as it relates to sustainable forest management and climate change.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (1) / Mestrado acadêmico: (1) . , Integrantes: Karen Amanda Harper - Coordenador., Financiador(es): Churchill Northern Studies Centre Northern Research Fund - Auxílio financeiro.

Spatial configuration of the forest-tundra ecotone and implications for climate change., Descrição: Our research is part of PPS Arctic Canada, the Canadian component of PPS Arctic, an International Polar Year research program on the causes and consequences of change of the forest-tundra ecotone (treeline zone). Our long-term objectives include modeling temporal and spatial treeline dynamics, assessing the impact of climate change on processes within the treeline ecotone, determing ecosystem services of the ecotone and their vulnerability with climate change and developing models of the relationship between environmental change and human health. Churchill is one of many sites across Canada where we will sample the forest tundra ecotone at different scales. Our research at Churchill, which will be compared to similar studies being conducted at an alpine treeline in Labrador, considers the spatial distribution of trees across the forest-tundra gradient at treeline. We expect that climate warming will change the current spatial pattern of treeline due to different patterns of tree growth and recruitment. The objectives for this research are: 1) to determine the current spatial configuration of treeline, 2) to assess the structure of forest edges within the forest-tundra ecotone and 3) to predict changes in spatial pattern with climate change using models in GIS. Transects will be established perpendicular to forest edges within the treeline ecotone to sample vegetation structure and composition. The current spatial distribution of trees will be mapped within large grids within the forest-tundra ecotone. Spatial configuration will be related to past, current and future treeline movement. Our International Polar Year research will help predict and show the effects of treeline migration on northern ecosystems and communities.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (2) . , Integrantes: Karen Amanda Harper - Coordenador., Financiador(es): Churchill Northern Studies Centre Northern Research Fund - Auxílio financeiro.

PPS Arctic Canada (Present processes, Past changes, Spatiotemporal variability in the Arctic delimitation zone, Canada)., Descrição: PPS Arctic Canada (Present processes, Past changes, Spatio-temporal variability in the Arctic delimitation zone, Canada) is the Canadian component of PPS Arctic, an IPY endorsed research program on the causes and consequences of change of the forest-tundra ecotone (the treeline). Together with international researchers we developed common protocols and collected data during IPY to examine change at the treeline. In the summers of 2007-09, we collected data at over a dozen locations in the Yukon, Northwest Territories, Nunavut, northern Manitoba, northern Quebec and Labrador. The results from these studies contribute to our short-term objectives: 1) an analysis of recent change in tree and shrub distributions, 2) the collection of environmental and microclimate data to accompany treeline change, 3) an investigation of the mechanisms of vegetation change at treeline, 4) the mapping of the spatial pattern of tree and non-tree species at treeline and in tundra islands within the boreal forest to predict future changes as treeline migrates, 5) an assessment of the role of disturbance, and 6) the development of models of the long-term relationship between environmental change, resource availability and human health and well-being in the forest-tundra ecotone. We conducted experimental and observational studies, trained students and actively engaged northern communities. We collected data on trees of all ages, seeds, vegetation, snow and ice, microclimate, spatial pattern, soil and socioeconomic indicators across the forest tundra ecotone at sites across northern Canada following common protocols developed by researchers in the international PPS Arctic. Additional data were collected regarding the impacts of changes in climatic conditions on treeline and their consequences on ecosystems and communities. Our key finding continues to be the large amount of variability in tree growth, regeneration and spatial pattern among tree species, regions across Canada and even sites wi. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (34) / Mestrado acadêmico: (42) . , Integrantes: Karen Amanda Harper - Coordenador / Gavin Kernaghan - Integrante / Trevor Bell - Integrante / Frank Berninger - Integrante / Stephane Boudreau - Integrante / Ryan Danby - Integrante / Shawn Donaldson - Integrante / Nancy Doubleday - Integrante / Scott Green - Integrante / Greg Henry - Integrante / Luis Hermanutz - Integrante / David Hik - Integrante / John Jacobs - Integrante / Jill Johnstone - Integrante / Peter G.
