Under rapid environmental change, opportunistic species may exhibit dramatic increases in
response to the altered conditions, and can in turn have large impacts on the ecosystem …

Many coastal and offshore fish species are highly dependent on specific habitat types for
population maintenance. In the Baltic Sea, shallow productive habitats in the coastal zone …

Regime shifts in ecosystem structure and processes are typically studied from a temporal
perspective. Yet, theory predicts that in large ecosystems with environmental gradients …

Abstract In the Baltic Sea, the mesopredator three-spined stickleback (Gasterosteus
aculeatus) spends a large part of its life cycle in the open sea, but reproduces in shallow …

The three-spined stickleback (Gasterosteus aculeatus L., hereafter 'stickleback') is a
common mesopredatory fish in marine, coastal and freshwater areas. In large parts of the …

We synthesize a large body of literature involving peer-reviewed work, grey literature and
novel data analyses about the small-scale northern pike (Esox lucius) fishery in lagoon …

Coastal predatory fish are of key importance for the provisioning of ecosystem services in
the Baltic Sea. Worldwide, however, there has been a general and sharp decline in …

Many fish populations have experienced declines in recent decades due to anthropogenic
disturbances, such as overfishing and habitat exploitation. Despite management actions …

To understand food web dynamics, knowledge about factors influencing trophic interactions
is fundamental. Using stomach content analysis, we investigated size-dependent predator …

Background Shallow nearshore marine ecosystems are changing at an increasing rate due
to a range of human activities such as urbanisation and commercial development. As a …
