Finding Prehistoric Rain Forests by Studying Modern Mammals
Mammal teeth store a record of the plants they ate, providing clues about the ecosystems in which they lived.
A Promising Development for Detecting Ocean Productivity
A comparison of primary productivity measurements across the North Pacific Ocean demonstrates the potential for using autonomous instruments to discern effects of climate change on the marine food web.
How Long Does Iron Linger in the Ocean’s Upper Layers?
A new study refines our understanding of marine residence times of iron, which supports carbon-sequestering sea life, offering valuable data to inform biogeochemical models.
Rising Seas and Agriculture Created Wetlands Along the U.S. East Coast
Most of the tidal marshes along the eastern coast of the United States formed within the past 6,000 years due to a combination of slowly rising seas and European colonization.
Linking Critical Zone Water Storage and Ecosystems
The geology and the structure of Earth’s critical zone control subsurface moisture storage potential and determine the resilience of forest and river ecosystems to drought.
Climate Change May Shift Coral Population Dynamics
New paleoceanographic research indicates that warming waters may contribute to fewer coral reefs but to a flourishing presence of soft-bodied corals.
How River Capture Affects the Evolution of Aquatic Organisms
River basins are dynamic environments that are always changing and reorganizing under geologic forces. New research investigates how this shape shifting influences aquatic speciation and extinction.
Most of the Arctic’s Microscopic Algae Are Chilling Under Ice
New research reveals that tiny single-celled organisms in the Arctic Ocean are growing more numerous as climate change thins the ice.
Los Costos Ecológicos de Remover las Plataformas Petroleras Mar Adentro en California
Las plataformas de perforación de petróleo- y gas-mar adentro son hábitats ricos para peces. Eliminarlas por completo resultaría en una pérdida del 95% de biomasa de peces, revela una nueva investigación.
