Human impacts on marine ecosystems

Human activities affect marine ecosystems as a result of pollution, overfishing, the introduction of invasive species,and acidification, which all impact on the marine food web and may lead to largely unknown consequences for the biodiversity and survival of marine life forms.

Clones - everything but identical

New study shows why asexual populations of plants or animals can thrive in nature

An alga of the genus Micromonas, for which the first transformation protocols are presented. Since Micromonas photosynthesizes with the chloroplast (shown here in green) and is very abundant in the ocean, it plays a role in the global carbon cycle.
