Sea otters keep remaining California kelp forests alive
2021/4/9
Sea otters have long been recognized as a classic example of a keystone species, a dominant predator that maintains the balance of kelp forest ecosystems by controlling populations of sea urchins, whi...

Chromatin organizes 3D forests single cells
2020/2/20
A single cell contains the genetic instructions for an entire organism. This genomic information is managed and processed by the complex machinery of chromatin -- a mix of DNA and protein in chromosom...
A new study in the journal Nature Sustainability overturns long-held interpretations of the role humans played in shaping the American landscape before European colonization. The findings give new ins...
In a world with rising levels of atmospheric carbon dioxide, experiments have shown that increased CO2 allows plants to photosynthesize more and use less water; however, warmer temperatures drive plan...
