Factors limiting the potential range expansion of lodgepole pine in Interior Alaska. Ecological Applications e2983.Understanding the factors influencing species range limits is increasingly crucial in anticipating migrations due to human-caused climate change. In the boreal biome, ongoing climate change and the associated increases in the rate, size and severity of disturbances may alter the distributions of boreal tree species. Notably, Interior Alaska lacks native pine, a biogeographical anomaly that carries implications for ecosystem structure and function. The current range of lodgepole pine (Pinus contorta var. latifolia) in the adjacent Yukon Territory may expand into Interior Alaska, particularly with human assistance. Evaluating the potential for pine expansion in Alaska requires testing constraints on range limits such as dispersal limitations, environmental tolerance limits, and positive or negative biotic interactions. Here, we archive the model results from a multi-disciplinary study. In the study, we used field experiments with pine seeds and transplanted seedlings, complemented by model simulations, to assess the abiotic and biotic factors influencing lodgepole pine seedling establishment and growth after fire in Interior Alaska.File list:README_Hansen_EcolApps_2024.pdf: Contains data dictionaries for all data tables, full list of creators/authors, methodology, and additional project documentation.Stand_LP.csv: Stand level output for trees taller than 4 m from simulations that included lodgepole pine.Stand_No LP.csv: Stand level output for trees taller than 4 m from simulations that did not include lodgepole pine.Saplingdetail_LP.csv: Stand level output for trees shorter than 4 m from simulations that included lodgepole pine.Saplingdetail_NoLP.csv: Stand level output for trees shorter than 4 m from simulations that included lodgepole pine.Sapling_LP.csv: Stand level output recording sapling output in the simulations that included lodgepole pine.Sapling_noLP.csv: Stand level output recording sapling output in the simulations that did not include lodgepole pine.Tree_LP.csv: Individual tree output in the simulations that included lodgepole pine.Tree_noLP.csv: Individual tree output in the simulations that did not include lodgepole pine.carbon_LP.csv: Stand level carbon pools from the simulations that included lodgepole pine.carbon_noLP.csv: Stand level carbon pools from the simulations that did not include lodgepole pine.
