Early naturalists suggested that predation intensity increases toward the tropics, affecting fundamental ecological and evolutionary processes by latitude, but empirical support is still limited. Several studies have measured consumption rates across latitude at large scales, with variable results. Moreover, how affects prey community composition such geographic scales remains unknown. Using standardized experiments spanned 115° of 36 nearshore sites along both coasts Americas, we found...
Understanding the impacts on Brazilian semi-arid coast, which is a drought-prone area (>1000 km) in tropical Atlantic, and how ecosystems survive adapt to such extreme environments requires socioecological studies create theory for conservation. Here, we highlight five main ongoing changes areas, namely (1) decrease rainfall rates due climate change, alters freshwater flows, water residence times, promotes hypersalinity (>37) low-inflow estuaries; (2) sea-level rise, groundwater hazards,...
Abstract Aim The present study uses marine prosobranchs from shallow waters (down to 200 m) as a model determine biogeographical units along the Brazilian coast and investigate changes in assemblages Western Atlantic. Location Atlantic Ocean. Methods composition species distribution of were determined using secondary data information gathered scientific collections. similarities among areas calculated Sørensen, Simpson Ochiai Indices, illustrated dendrograms constructed by unweighted pair...
Abstract Large gaps in reef distribution may hinder the dispersal of marine organisms, interrupting processes vital to maintenance biodiversity. Here we show presence and location extensive habitats on continental shelf between Amazon Reef System (ARS) Eastern Brazilian (ERS), two complexes off eastern South America. Formations located 20–50 m deep include both biogenic geogenic structures. The diverse assemblages suggests widespread occurrence rocky substrates below 50 m. These represent an...
Coastal reef environments support a great diversity of benthic species, which are physically arrayed according to their adaptations biotic factors such as competition and abiotic salinity desiccation. Few studies have described adaptive strategies on rocky shores in tropical regions. This contribution deals with the spatial distribution three species zoanthids (Palythoa caribaeorum, Protopalythoa variabilis Zoanthus sociatus) flat sandstone reefs north-eastern Brazil. Zoanthid abundances...
Sessile organisms that live in consolidated substrates frequently compete for space. Coral species have many strategies to face this competition, including harming their opponents or hindering growth. In the present study, competitive interactions between three of zoanthids were investigated intertidal zone a sandstone reef environment northeastern Brazil. The abilities evaluated by periodic observation natural fringes contact and experimental evaluation growth rate through removal 100 cm²...
The influence of abiotic factors on the spatial distribution fiddler crabs Uca leptodactyla, U. maracoani, rapax and thayeri was studied in a tropical mangrove northeast Brazil.Eight transects were delimited area Pacoti River.On each transect, three 0.25 m 2 squares sampled during spring low tide periods from September 2003 to August 2004.The sediment at transect analysed for grain size, organic matter humidity.Morphology second maxilliped considering number spoon-tipped setae help explain...
One of the main difficulties in taxonomy heterobranch sea slugs is interpretation small morphological and body colour differences a group specimens, sympatric or allopatric, as variation single species indicative similar, but different, species. The aeolid Cratena peregrina one most common typical nudibranchs from Mediterranean Sea was recently informally recorded Senegal, South Africa, India western Atlantic. In present work, we investigate potential presence C. on coast Brazil. Brazilian...
Suitable colonization materials are a pursued target in marine restoration programs. Known for making nutrients available while reducing pollutants and the risk of pathogens terrestrial ecosystems, Biochar Bioferment organic origin were tested during two-year experiment. We efficacy these purposes through experimental concrete tiles treated with (B) (F) made concrete, which used as controls (Ct) organisms protected area Porto Cesareo, Southern Italy (20 m depth). Tiles monitored photographs...
The use of antifouling paints containing the biocide compound tributyltin (TBT) has been shown as an inductor imposex in neogastropods mollusks. Imposex is characterized by development male features females, mainly appearance a no functional vas deferens and penis. Samples Thais rustica were collected eight sites metropolitan area Natal city, Rio Grande do Norte state, northeast Brazil, examined for occurrence imposex, which was found many females. higher levels presented samples from near...
Imposex is characterized by the development of masculine sexual organs in neogastropod females. Almost 120 mollusk species are known to present imposex when exposed organic tin compounds as tributyltin (TBT) and triphenyltin (TPT). These used biocide agents antifouling paints prevent incrustations on boats. Five gastropod Brazil: Stramonita haemastoma, rustica, Leucozonia nassa, Cymathium parthenopeum Olivancillaria vesica. This paper reports first record observed endemic Voluta ebraea from...
Encapsulation of embryos in marine gastropods affords protection for the developing young, whether or not parental care takes place. The capsule wall is laminated and its dimensions change during development. Dissolution releases dissolved organic matter (DOM) into intracapsular fluid, providing a nutritional source embryo. Acanthina monodon composed three layers, thin outer layer with projections to exterior, thicker intermediate containing vacuoles inner that gives rise hatching plug....

The living corals create a variety habitats for large number species, giving support sedentary...
