Marine renewable energy: potential benefits to biodiversity? An urgent call for research
Summary 1. The evidence for anthropogenically induced climate change is overwhelming with the production of greenhouse gases from burning fossil fuels being a key driver. In response, many
A testable linear model for diversity trends in estuaries
Summary 1. In 1934, Adolf Remane constructed a diagram to describe changes in the number of species along a full salinity gradient within the Baltic. Despite fundamental differences in tidal regimes,
Climatic influence on a marine fish assemblage
It is shown that, during a 16-year period, climatic forcing (by means of the NAO) is consistently the most important parameter explaining variation in assemblage composition, abundance and growth of juvenile marine fish during estuarine residency.
Are macroinvertebrate communities influenced by seagrass structural complexity
The results suggest that within a seagrass bed the size and composition of the associated macroinvertebrate community is not determined by the structural complexity of the plants, but by the amount of plant available.
Climate‐related increases in jellyfish frequency suggest a more gelatinous future for the North Sea
Jellyfish frequency increased in the mid-1980s, coincident with the reported regime shift in the North Sea and tracking trends in phytoplankton color, and it is suggested that jellyfish frequency will increase over the next 100 yr.
Ecotone or Ecocline: Ecological Boundaries in Estuaries
Abstract Two main ecological boundaries, ecotone and ecocline, have been defined in landscape ecology. At this scale, the estuary represents a boundary between rivers and the sea, but there has been
A long‐term chlorophyll dataset reveals regime shift in North Sea phytoplankton biomass unconnected to nutrient levels
During the 1980s, a rapid increase in the Phytoplankton Colour Index (PCI), a semiquantitative visual estimate of algal biomass, was observed in the North Sea as part of a regionwide regime shift.
Juvenile Chinese mitten crabs (Eriocheir sinensis) in the Thames estuary: distribution, movement and possible interactions with the native crab Carcinus maenas
Intertidal surveys along the Thames estuary indicated an increase in the population since the 1990s, and juvenile E. sinensis juveniles can successfully exclude similar sized native Carcinus maenas from shelters in the laboratory, regardless of which species originally inhabited the shelter.
Estimating marine species richness: an evaluation of six extrapolative techniques
The number of species in an assemblage at a given point in time is a fundamental prop- erty of ecological systems, yet it is hard to quantify for many marine systems. We studied the perfor- mance of
