Coral architecture affects the habitat choice and form of associated gobiid fishes
Gobiid fishes of the genus Gobiodon live in strong association with certain reef-building corals that vary considerably in size and architecture. These fishes hence are excellent model systems for studying evolutionary adaption to specific microhabitats. Using a sample of Gobiodon histrio and G. rivulatus and their most important host corals (Acropora digitifera and A. gemmifera) from the north...
متن کاملCryptic effects of habitat declines: coral-associated fishes avoid coral-seaweed interactions due to visual and chemical cues
Seaweed-dominated coral reefs are becoming increasingly common as environmental conditions shift away from those required by corals and toward those ideal for rampant seaweed growth. How coral-associated organisms respond to seaweed will not only impact their fate following environmental change but potentially also the trajectories of the coral communities on which they rely. However, behaviora...
متن کاملDistribution of coral reef fishes along a coral reef–seagrass gradient: edge effects and habitat segregation
Coral reefs and seagrass beds are often located adjacent to one another, but little is known about the degree to which their fish communities are interlinked. To determine whether coral reef fishes on the coral reef are interlinked with or segregated from fishes on adjacent seagrass beds, a 60 m coral reef–seagrass gradient was studied on the island of Zanzibar in the western Indian Ocean. Usin...
متن کاملDNA barcoding of gobiid fishes (Perciformes, Gobioidei).
Gobiids constitute a major proportion of fish population in both tropical and temperate freshwater as well as marine ecosystem. Due to their small size, cryptic ecology and ambiguous morphological characters, gobiids diversity was not documented completely. In this study, DNA barcodes were generated for 11 species of gobiids, collected from the Ashtamudi Lake, India. The mitochondrial COI gene ...
متن کاملHabitat choice, recruitment and the response of coral reef Wshes to coral degradation
The global degradation of coral reefs is having profound eVects on the structure and species richness of associated reef Wsh assemblages. Historically, variation in the composition of Wsh communities has largely been attributed to factors aVecting settlement of reef Wsh larvae. However, the mechanisms that determine how Wsh settlers respond to diVerent stages of coral stress and the extent of c...
