• Abstract

  AimsThe importance of biotic interactions in creating and maintaining diversity is expected to increase toward low latitudes. However, the way in which predation affects diversity, can depend on how predators mediate competitive interactions and also on defensive traits of prey. Here we assessed the role of physical defences of prey to escape predation and how the importance of predation …

• Abstract

  Marinas, harbors and piers increase the availability of substrate for the development of sessile communities but are also associated with a range of sources of anthropogenic disturbance. Pollution, reduced top-down control and other disturbances in artificial habitats tend to exclude some native species, facilitating the introduction of non-indigenous species and determining that artifici…

• Abstract

  Colour change is a common process shaping animal appearance and promoting camouflage in nature. However, the relationship between colour plasticity and camouflage in the reduction of predation risks, as well as the selective pressures and the evolutionary mechanisms involved, are normally explored in a few taxonomic groups. Benthic crustaceans are interesting biological models to answer t…

  Colour change and camouflage in coastal benthic crustaceans: occurrence, selective pressures and ecological function, BP.PD

• Abstract

  Reef environments are threatened by anthropogenic pressures such as overfishing and eutrophication. Those activities can change benthic communities, increasing algae abundance and biomass, excluding corals species. Algae dominate most rocky shores on the north coast of Sao Paulo, except for Alcatrazes Island where corals and herbivore reef fishes are very abundant. This project aim to des…

• Abstract

  Many animals are able to change colour over different timescales to camouflage against variable backgrounds, allowing them to cope with spatial and temporal uncertainty on the availability of substrates. However, while colour change is known to improve prey's concealment and reduce detection by visual predators, little is known about how this relationship is affected by different anthropo…
