Species belonging to different sections of the genus Polygonum L. were studied micro-morphologically. For this purpose, digital images were obtained from all species and lower taxa belonging to sections Persicaria, Bistorta, Tiniaria and Pleuropterus. Since section Polygonum is much diverse, pollens of three representative species Polygonum luzuloides, P. olivascens and P. setosum were photogra...

The massive die-off of the sea urchin Diadema antillarum in 1983–1984 is one main reasons for low coral recruitment and little recovery Caribbean. As natural D. slow to non-existent, multiple restoration studies have been attempted. There are currently three different approaches obtain individuals restocking: translocation wild-collected juveniles or adults, lab-reared cultured from settlers, g...

Egg size is one of the fundamental parameters in the life histories of marine organisms. However, few studies have examined the relationships among egg size, composition, and energetic content in a phylogenetically controlled context. We investigated the associations among egg size, composition, and energy using a comparative system, geminate species formed by the closure of the Central America...

An ethnopharmacological survey conducted among migrants living in the Southeast Atlantic Forest remnants (Diadema, São Paulo, Brazil) is presented herein. METHODS Eth...
