News Finding: Many species groups are affected by this issue, and modeling at finder spatial scales can only partially mitigate that, the researchers say.
Paper Finding: The projected future convergence of priority sites for narrow-and wide-ranging amphibians may therefore echo historical processes underlying contemporary biodiversity patterns.
News Context: That's the finding of a case study focusing on amphibians in Africa, are large number of which are on the brink of extinction. Many species groups are affected by this issue, and modeling at finder spatial scales can only partially mitigate that, the researchers say. Of those, 400 had too few existing records to allow modeling their distribution on continental scales.
Paper Context: These patterns are consistent with the theory that long-term climatic stability, combined with topographic complexity and geographic isolation, gives rise to, and may continue supporting, high rates of rarity and endemism . The projected future convergence of priority sites for narrow-and wide-ranging amphibians may therefore echo historical processes underlying contemporary biodiversity patterns. The 1°resolution used here is, however, too coarse to capture the variations in local climate, biotic interaction and adaptive potential that are ultimately central to species persistence under climate change .
