This study demonstrates how herbivore grazing and substrate variations influence coral recruitment patterns at the Flower Garden Banks, Gulf of Mexico, for two brooding coral species, Agaricia spp. and Porites spp. Three herbivore treatments, two tile textures and two tile orientations were tested. Herbivore grazing significantly affected coral recruit growth for both species. These data sugges...

OBJECTIVE To evaluate the association between gender and use of alcohol, tobacco, and other drugs in adolescents aged 10 to 18 years in the municipalities of Jacareí and Diadema, São Paulo, Brazil. METHODS A total of 971 adolescents completed the Drug Use Screening Inventory (DUSI). RESULTS In our sample, 55% of adolescents were male, 33.8% reported having made use in the previous month of ...

The object of this study is the development of therapeutic projects by the team working in a Psychosocial Care Center (CAPS III). It takes into consideration the creation and expansion process of the Brazilian public health system (SUS) and Psychiatric Reform. In this context, workers are challenged to develop care through an individual therapeutic project that considers the true needs and life...

Use of plant based drugs and chemicals for curing various ailments and personal adornment is as old as human civilization. Plants and plant-based medicaments are the basis of many of the modern pharmaceuticals we use today for our various ailments. The aim of the study was to find out the bioactive chemical constituents and to evaluate the antimicrobial activity of the ethanolic extract of trad...

Natural and anthropogenic stressors can cause phase shifts from coral-dominated to algal-dominated states. In the Caribbean, over-fishing of large herbivorous fish and disease among the long-spined urchin, Diadema, have facilitated algal growth on degraded reefs. We found that diminutive species of urchin and parrotfish, which escaped die-offs and fishing pressure, can achieve abundances compar...

Coral reefs have undergone profound ecological changes over recent decades. Areas formerly covered by scleractinian coral species are now often overgrown by macroalgae. In Martinique (West Indies), this phenomenon has lead to the colonisation of numerous coral reefs by algae, amongst which Sargassum is one of the most prominent. This study focuses on potential defence molecules produced by Sarg...

The massive die-off of the herbivorous sea urchin Diadema antillarum in 1983 and 1984 resulted phase shifts on Caribbean coral reefs, where macroalgae replaced as most dominant benthic group. Since then, D. recovery has been slow to non-existent reefs. Studying settlement rates can provide insight into mechanisms constraining antillarum, while efficient collectors be used identify locations wit...

The 1983-1984 die-off of the long-spined sea urchin Diadema antillarum stands out as a catastrophic marine event because its detrimental effects on Caribbean coral reefs. Without grazing activities this key herbivore, turf and macroalgae became dominant benthic group, inhibiting recruitment compromising reef recovery from other disturbances. In decades that followed, D. populations was slow to ...
