Red Sea Corals Survived the Late Glacial Crisis
Research indicates that delicate deepwater corals tolerated or adapted to major climate and salinity fluxes, “yet today, it’s a complete massacre.”
El ADN de los sedimentos lacustres revelan el impacto de los peces introducidos
La trucha no nativa ha alterado la diversidad del zooplancton que habita en los lagos de gran elevación.
Coastal Dynamics Revealed by Satellite Salinity Data
One decade of high-quality satellite salinity observations provide valuable insights into the complex dynamics in the Mid-Atlantic Bight.
Sensing Potential, Scientists Refine Thermal Imaging of Ecosystems
At a recent “bake-off,” researchers judged thermal infrared cameras and developed guidelines for their consistent use in studying vegetation temperatures, which illuminate vital ecosystem processes.
Filling the Gaps: Context and Design of Arctic Carbon Flux Measurement Networks
Large scale observational networks are necessary for understanding the impact of a warming climate in the Arctic, but critical tools are crucial to how those networks are designed.
Three-Quarters of the World’s Land Is Drying Out, “Redefining Life on Earth”
Climate change has made great swaths of the planet drier and soils saltier, jeopardizing food production and water access for billions.
DNA in Lake Sediment Reveals the Impact of Introduced Fish
Non-native trout have altered the diversity of zooplankton that live in high-elevation lakes.
As Seas Rise, Marshes May Still Trap Carbon—and Cool the Planet
Rising seas spell doom for coastal wetlands trapping carbon—or do they? New research reveals that as these ecosystems transition, they can still trap carbon and possibly cool the planet.
Planetary Perturbations May Strengthen Gaia
Large-scale disruptions to life may ultimately increase ecological complexity over geologic timescales, though the risk of extinction always looms.
