Across time, but also across space

摘要: Paleontology Fossils, especially those from marine systems, have long been used to estimate changes in patterns of diversity over time. However, fossils are patchy their occurrence, so such temporal estimates generally not included variations due space. Such a singular examination has the potential simplify, or even misrepresent, patterns. Close et al. spatially explicit approach measure across time and They found that, like modern varies considerably space, with reefs increasing levels. Accounting for this spatial-environmental variation will shed new light on study time. Science , issue p. [420][1] [1]: /lookup/doi/10.1126/science.aay8309
