Differences with respect to anti-herbivore defense were investigated in invasive and native
populations of the seaweed Gracilaria vermiculophylla. S pecimens from 6 native …

Ecological impacts of top-down trophic cascades in combination with bottom-up nutrient
enrichment are increasingly being reported. Such effects may be triggered by decline in the …

Although the establishment and spread of non-indigenous species depends upon survival in

In many temperate estuarine areas, ongoing climatic changes are expected to lead to higher
seawater temperatures, to increased inflow of freshwater and nutrients (due to increased …

In marine ecosystems, carbon export is driven by particle flux which is modulated by
aggregation, remineralization, and grazing processes. Zooplankton contribute to the sinking …
