Soil-carbon turnover in the Nile River basin accelerated by an order of magnitude due to post-glacial warming and led to release of CO2 into the atmosphere. Itstemperaturesensitivity is higher ...
Across alltropicalcontinents and using 36 published studies, we assessedtemperaturebuffering from within microhabitats across varioushabitatstrata and structures (e.g. soil, logs, epiphytes and tree holes) and compared them to non-buffered macro-scale ambienttemperatures(the thermalcontrol).
The study area belongs to the middlesubtropicalwarm and humid climate zone and is significantly influenced by the monsoon. The mean annualtemperaturein the low elevation (∼440 m) is 16.2 °C, with atemperatureof 26.1 °C in July and atemperatureof 4.5 °C in January.
In summary, the dominantcontroloftemperatureon (sub-)tropicalsoil carbon turnover elucidated in this landmark study sharpens our understanding of climate-carbon feedbacks. It compels the scientific community and stakeholders worldwide to consider soiltemperaturedynamics as central to future climate resilience strategies.
Here, we use radiocarbon dating of plant-derived lipids in conjunction with reconstructions oftemperatureand rainfall from an eastern Mediterranean sediment core receiving terrigenous material ...
Summary: To explain current species distribution patterns and predict future patterns, multilevel (behavior to molecules) biological variation in thermal responses must be paired with refined spatiotemporal analyses ofhabitattemperaturevariation.
Our study provides data-based evidence for a reduction in mean soil carbon turnover time and soil mean carbon ages by an order of magnitude in (sub-)tropicalAfrica during the last deglaciation.
