摘要：Forestation (afforestation and reforestation) could mitigate climate change by sequestering carbon within biomass and soils. However, global mitigation from forestation remains uncertain owing to varying estimates of carbon sequestration rates (notably in soil) and land availability. In this study, we developed global maps of soil carbon change that reveal carbon gains and losses with forestation, primarily in the topsoil. Constraining land availability to avoid unintended albedo-induced warmi...

摘要：A primary axiom in geoscience is that the evolution of plants drove global changes in river dynamics. Notably, the apparent sinuosity of rivers, derived from the variance of sediment accretion direction measured in rocks, substantially increased when land plants evolved, around 425 million years ago. This led to the hypothesis that the rise of vegetation triggered river meandering. Recent studies of barren, meandering rivers challenge this notion, but the Paleozoic shift in the geometry of riv...

摘要：Vegetation in river valleys slows floodplain erosion rates (1), reduces river channel widths (2), and drives a transition from braided, multichannel rivers to single-channel, meandering rivers (3). These changes also control carbon sequestration and other biogeochemical processes along river channels (4). On page 915 of this issue, Hasson et al. (5) report a new way in which floodplain vegetation-the plant life found in flat land adjacent to a river-controls river dynamics. Meandering rivers i...

摘要：Horsepower revolutionized human history through enhanced mobility, transport, and warfare. However, the suite of biological traits that reshaped horses during domestication remains unclear. We scanned an extensive horse genome time series for selection signatures at 266 markers associated with key traits. We detected a signature of positive selection at ZFPM1-known to be a modulator of behavior in mice-occurring similar to 5000 years ago (ya), suggesting that taming was one of the earliest ste...
