Novel carbon source sustains deep-sea microorganism communities

The first in-depth analyses of dissolved organic carbon (DOC) cycling in the Red Sea highlights the important role of migrating shoals of fish in sustaining deep-ocean microorganisms and potentially the global carbon cycle.

Earth's oxygen increased in gradual steps rather than big bursts

A carbon cycle anomaly discovered in carbonate rocks of the Neoproterozoic Hüttenberg Formation of north-eastern Namibia follows a pattern similar to that found right after the Great Oxygenation Event, hinting at new evidence ...

Species-rich forests better compensate environmental impacts

To offset CO2 emissions, China is reforesting. If a mixture of tree species instead of monocultures were planted, much more carbon could be stored. An international team including UZH researchers has shown that species-rich ...

New method could save iconic English chalk grasslands

A three-year experiment by ecologists from The University of Manchester, the Centre for Ecology & Hydrology and Lancaster University has revealed how our iconic chalk grasslands—damaged by intensive farming—could be regenerated.

Expedition probes ocean's smallest organisms for climate answers

Satellite images of phytoplankton blooms on the surface of the ocean often dazzle with their diverse colors, shades and shapes. But phytoplankton are more than just nature's watercolors: They play a key role in Earth's climate ...

The value of seagrass in securing a sustainable planet

Researchers believe that improving knowledge of how seagrasses are important for biodiversity, fisheries and our global carbon cycle in turn needs to be reflected with greater protection for these sensitive habitats.
