General mechanisms for a top–down origin of the predator–prey power law
The ratio of predator‐to‐prey biomass density is not constant along ecological gradients: denser ecosystems tend to have fewer predators per prey, following a scaling relation known as the ‘predator–prey power law'. The origin of this surprisingly general pattern, particularly its connection with environmental factors and predator–prey dynamics, is ...

ABSTRACT Phytoplankton blooms create a substrate‐rich environment that supports the growth of bacterial planktonic heterotrophs. Previously, we studied the dynamics of such bacterioplankton at a long‐term ecological research site near the coast of Helgoland Island (North Sea) once a day.

ABSTRACT The confluence of rivers with the ocean creates biological hotspots where temperature, salinity, and nutrients mix to provide excellent conditions for rearing, growth, and refuge to a multitude of organisms. Worldwide, estuaries are highly productive and biodiverse.
