      "excerpt": "Our results show how the current regional tree flora was progressively filtered towards the colder and drier margins of climate space. This coincided with the losses of most heat-tolerant lineages. The study fit genus-level niche models for tree genera that had a presence in Western and Central Europe during the Cenozoic. Climatic centers of regionally extinct and extant genera were estimated using all available tree species within each genus globally, whereas the Holocene regional tree flora used only native species pools of Western and Central Europe. Current climate was 1981–2010; five of 237 attempted models were excluded from the plot because of convergence problems.",

  "searched": "Read the primary Nature Communications article, including abstract, climate-space results, figure 4 caption, discussion, and model methods. Checked whether the filtering statement was bounded by population, time, climate baseline, model construction, and sampling/model exclusions. The study concerns 200 tree genera in Western/Central Europe; genus-level climate centers use species occurrences and CHELSA climate data, with extant/regionally extinct genera modeled from all globally available tree species but the Holocene regional flora from native Western/Central European species only. Current climate is 1981–2010, and five climate models were excluded for convergence problems."
