To anticipate the rapidly changing world resulting from global climate change, the projections ofclimate models must be incorporated into conservation. This requires that the scales of conservation be alignedwith the scales of climate-change projections. We considered how conservation has incorporated spatial scaleinto protecting biodiversity, how the projections of climate-change models vary with scale, and how the twodo or do not ...Fire regimes result from reciprocal interactions between vegetation and fire that may be further affected by other disturbances, including climate, landform, and terrain. In this paper, we describe fire and fuel extensions for the forest landscape simulation model, LANDIS-II, that allow dynamic interactions among fire, vegetation, climate, and landscape structure, and incorporate realistic fire characteristics (shapes, distributions, and effects) that ...
Differences in spatial predictions among species distribution modeling methods vary with species traits and environmental predictorsPrediction maps produced by species distribution models (SDMs) influence decision-making in resource management or designation of land in conservation planning. Many studies have compared the prediction accuracy of different SDM modeling methods, but few have quantified the similarity among prediction maps. There has also been little systematic exploration of how the relative importance of different predictor variables varies among model ...
Species' traits affect the performance of species' distribution models for plants in southern CaliforniaQuestions: To what extent do plant species traits, including life history, life form, and disturbance response characteristics, affect the degree to which species distributions are determined by physical environmental factors? Is the strength of the relationship between species distribution and environment stronger in some disturbance-response types than in others? Location: California southwest ecoregion, USA. Methods: We developed species distribution models ...
Conservation threats due to human-caused increases in fire frequency in Mediterranean climate ecosystemsPeriodic wildfire is an important natural process in Mediterranean-climate ecosystems, but increasing fire recurrence threatens the fragile ecology of these regions. Because most fires are human-caused, we investigated how human population patterns affect fire frequency. Prior research in California suggests the relationship between population density and fire frequency is not linear. There are few human ignitions in areas with low ...
