Abstract Aim The assumption of equilibrium between organisms and their environment is a standard working postulate in species distribution models (SDMs). However, this typically violated biological invasions where range expansions are highly constrained by dispersal colonization processes. Here, we examined how stage invasion affects the extent to which occurrence data represent ecological niche and, turn, influences spatial prediction species’ potential distributions. Location Six...
Significance In many landscapes across the globe, we are witnessing an ongoing functional shift away from managed for extractive activities (e.g., agriculture, mining, forestry) and toward recreation leisure activities. Understanding spatial configuration of this at regional continental scales will be crucial development effective landscape rural policies in coming decades. We present a rigorous comparison between three social media platforms’ suitability mapping quantifying values. also...
Significance We use sudden oak death in California to illustrate how mathematical modeling can be used optimize control of established epidemics invading pathogens complex heterogeneous landscapes. our statewide model—which has been parameterized pathogen spread data—to address a number broadly applicable questions. How quickly must management start? When is an epidemic too large prevent further effectively? should local treatment deployed? does this depend on the budget and level risk...
The spread of emerging infectious diseases (EIDs) in natural environments poses substantial risks to biodiversity and ecosystem function. As EIDs their impacts grow, landscape- regional-scale models disease dynamics are increasingly needed for quantitative prediction epidemic outcomes design practicable strategies control. Here we use spatio-temporal, stochastic epidemiological modeling combination with realistic geographical predict the sudden oak death pathogen (Phytophthora ramorum)...
Abstract We present a multilevel modeling framework for simulating the emergence of landscape spatial structure in urbanizing regions using combination field-based and object-based representations land change. The FUTure Urban-Regional Environment Simulation (FUTURES) produces regional projections patterns coupled submodels that integrate nonstationary drivers change: per capita demand, site suitability, conversion events. Patches change events are simulated as discrete objects stochastic...
Summary 1. Few pathogens are the sole or primary cause of species extinctions, but forest disease has caused spectacular declines in North American overstorey trees and restructured ecosystems at large spatial scales over past 100 years. These events threaten biodiversity associated with impacted host other resources valued by human societies even when they do not directly extinction. 2. Invasion Phytophthora ramorum emergence sudden oak death a large‐scale decline tanoak ( Notholithocarpus...
Landscapes are increasingly recognized for providing valuable cultural ecosystem services with numerous non-material benefits by serving as places of rest, relaxation, and inspiration that ultimately improve overall mental health physical well-being. Maintaining enhancing these through targeted management conservation measures requires understanding the spatial temporal determinants perceived landscape values. Content contributed mobile technologies web emerging globally, a promising data...
Expansion of urban settlements has caused observed declines in ecosystem services (ES) globally, further stressing the need for informed development and policies. Incorporating ES concepts into decision making process been shown to support resilient functional ecosystems. Coupling land change models allows insights impacts anticipated trade-offs specific policy decisions. The spatial configuration urbanization likely influences delivery production ES. When considering multiple...
Abstract Floods are the leading cause of natural disaster damages in United States, with billions dollars incurred every year form government payouts, property damages, and agricultural losses. The Federal Emergency Management Agency oversees delineation floodplains to mitigate but disparities exist between locations designated as high risk where flood occur due land use climate changes incomplete floodplain mapping. We harnessed publicly available geospatial datasets random forest...
Models that are both spatially and temporally dynamic needed to forecast where when non-native pests pathogens likely spread, provide advance information for natural resource managers. The potential US range of the invasive spotted lanternfly (SLF, Lycorma delicatula) has been modeled, but until now, it could reach West Coast's multi-billion-dollar fruit industry unknown. We used process-based modeling spread SLF assuming no treatments control populations occur. found a low probability first...
Summary Sudden oak death is an emerging forest disease caused by the pathogen Phytophthora ramorum that invading west coast of United States and semi‐natural areas in Europe. This causes lethal stem infections oaks ( Quercus spp.) tanoak Lithocarpus densiflorus ), as well non‐lethal foliar a range other species. We investigated two questions to evaluate effect landscape structure on spread P. : (i) does spatial pattern forested habitat predict severity, this relationship scale‐dependent;...
