Mathias Wegner Parasites [...] on transgenerational plasticity (parental environment effects on offspring traits) in response to ocean warming. So far, I can say that maternal effects play an important role in populations’ adaptive responses

Molecular Sea Ice Ecology Polar oceans are seasonally covered by sea ice with an average size of the continent of North America. Despite harsh conditions therein, sea ice and its lower surface can carry [...] community, typically dominated by Diatoms. Sea ice can provide important primary production to polar oceans via these communities, although they are often very patchy. In times of declining sea ice coverage [...] biodiversity, functions provided by its biota, and the future of sea ice communities in a warming ocean.
