Rapid biotic homogenization of marine fish assemblages
The role human activities play in reshaping biodiversity is increasingly apparent in terrestrial ecosystems. However, the responses of entire marine assemblages are not well-understood, in part, because few monitoring programs incorporate both spatial and temporal replication. Here, we analyse an exceptionally comprehensive 29-year time series of North Atlantic groundfish assemblages monitored ...
متن کاملArtificial waterway design affects fish assemblages in urban estuaries
Fishes were collected from residential canal estates leading directly off natural estuaries and artificial lakes with control tidal exchange in south-east Queensland, Australia, to test the model that the difference in artificial waterway design affects fish assemblages. A total of 17 779 fish representing 52 species was caught, including 23 species of economic importance (45% of the catch). To...
متن کاملDifferences in trophodynamics of commercially important fish between artificial waterways and natural coastal wetlands
Extensive artificial waterways have replaced natural wetlands and created new estuarine habitats on the southernQueensland coast, Australia. Economically important fish species found in adjacent natural wetlands of mangrove, saltmarsh and seagrass also occur in the artificial waterways. Stable isotope analyses (dC, dN)were used to test whether the relative importance of basal sources of energy ...
متن کاملFish Assemblages on Estuarine Artificial Reefs: Natural Rocky-Reef Mimics or Discrete Assemblages?
If the primary goal of artificial reef construction is the creation of additional reef habitat that is comparable to adjacent natural rocky-reef, then performance should be evaluated using simultaneous comparisons with adjacent natural habitats. Using baited remote underwater video (BRUV) fish assemblages on purpose-built estuarine artificial reefs and adjacent natural rocky-reef and sand-flat ...
متن کاملGlobal extent and distribution of artificial, residential waterways in estuaries
Artificial residential waterways are now widespread in the world’s estuaries. We used the global mapping tool, Google Earth, to determine that there are nearly 4000 linear km of artificial waterways globally, covering an area of 270 km2. Residential waterways constructed as open, flow-through canal estates are at their greatest extent in North America (77% of global linear extent), where system...
