1. Reproductive Biology of Varronia curassavica Jacq. (Boraginaceae)
ABSTRACT Varronia curassavica, a subshrubby medicinal species associated with restinga in the Atlantic Forest, has been exploited by local people and the pharmaceutical industry. Indeed, restingas have experienced a continuous process of degradation, and thus, with species and ecosystem both at risk, efforts to support conservation actions are required. The

2. Fenologia, ecologia da polinizaÃÃo e reproduÃÃo de espÃcies de manguezal, no municÃpio de Goiana - PE
The mangal is a tropical ecosystem of the coastal and estuarine areas, and it is important to shelter the marine animals and for its reproduction, beside promote the increase of productivity of neighbor community. Its vegetation, the mangrove, is composed of a few species with proper feature, such as viviparity and aerial roots associated with breath. There

3. Morpho-functional characteristics of sex reversal in Synbranchidae (Teleostei: Synbranchiformes) / Perfil morfo-funcional da inversão de sexo em Synbranchidae (Teleostei: Synbranchiformes)
Teleost fishes exhibit several sexual patterns during their ontogeny, in which the gonads change into functional ovaries or testes. In distinct Orders, both gonochoristic and hermaphrodite species, simultaneous as well as sequential or consecutive, can be found. In sequential hermaphroditism (protandrous or protogynous), sex change in adult individuais invol

4. Fenologia, polinização e reprodução de duas especies de Croton (Euphorbiaceae) em mata semidecidua
The phenology, pollination and mating systems of Croton floribundus and C. priscus (Euphorbiaceae) were studied in a semideciduous forest in Campinas, São Paulo, from 1993 to 1994. The species are pioneer monoecious trees, that bear bissexual racemose inflorescences, with unissexual and inconspicuous flowers. These species blossom in the wet season, from Oc

5. Brood insurance via protogyny: a source of female-biased sex allocation.
Sex allocation patterns and colony productivity are examined in Exoneura nigrescens, a social allodapine bee. As for previous studies on Australian allodapine bees, numerical sex ratios were strongly female biased in the smallest broods, but neared equality in larger broods. Local fitness enhancement has been suggested previously to explain female-biased all
