To protect species, we need to know where they are, but high-resolution maps for vascular plants are lacking at a global scale. Here, I produce high-resolution native range maps for vascular plants at the species-level usinginformaticsapproaches that enable accurate assessment of biogeography patte...
concentrations of 50 to ≤200 mg Cl−/L are classified as slightly polluted by salts, and concentrations of 200 to 400 mg Cl−/L are classified as moderately polluted by salts, while the drinking water guideline is 250 mg Cl−/L across much of Europe [e.g., Sweden (23)]. At ...

Finally, we investigated how variation in predation rates (surrogate of natural control) cascades to within-field weed and pest abundances, hence their regulation. 增加景观异质性被认为是加强作物自然病虫害控制的重要策略,特别是通过增加半自然栖息地的数量。在半自然栖息地稀缺的情况下,增加作物多样性也是一...
