Endemic pathogens continue to pose threats of recurring outbreaks, especially in agricultural settings. How these outbreaks unfold and what drives the variability in disease epidemics is less understood. We addressed this question in the Xanthomonas ‐tomato pathosystem by developing an integrated approach that linked the within‐field quantitative signature of local pathogen diversity to climatic conditions to explain variable...

Aim The climate tolerances of many species are broader than those estimated from current native ranges. Indeed, the niches of some Afromontane trees are up to 50% larger after incorporation of fossil data. This expansion could reduce estimates of species' future range loss owing to climate change but also implies strong non‐climatic limitations on species' current ranges. One such limitation is land use, which fossil data sugg...

Aim Climate and land‐use change will have a dramatic impact on future ecosystems through alterations to species ranges and community composition. When forming conservation strategies, correlative species distribution models are often created to assess risks for individual species. These models are based on the assumption of climatic equilibrium, such that the modern range is representative of the full range of conditions under...
