This study examined species richness and relative abundance of eusocial Apidae in an insular region of rain-forest, southeastern Brazil. Sampling took place during one year, using an standardized method with entomological net, at sites of secondary growth habitats surrounded by Atlantic rain-forest. Thirteen species of eusocial Apidae were netted at flowers, over 80% of the captured individuals were meliponine species, although the presence of Apis mellifera, commonly dominant in Brazilian habitats. Foraging activity of these bee species were essentially non-seasonal, apparently affected by high humidity. The patterns in abundance and species richness observed in Ilha Grande differed with other studies conducted at tropical islands, which were characterized by the poverty of meliponine species.

The Marambaia is an important natural refuge for preserving the genetic heritage of several rain forest plant species. In this insular region, where the vegetation types are Lower Montane Rain Forest and restingas (sandy coastal plain habitat), the impressive diversity of Melastomataceae consists of seven genera and 25 species of which 13 represent new records for the area. Miconia is best represented with 10 species, followed by Tibouchina (6 spp.), Leandra (4 spp.), Clidemia (2 spp.) and Huberia, Marcetia and Ossaea (1 sp. each). Most of the species are shrubs or trees and occur in Dense Submontane Ombrophilous Forest. Huberia ovalifolia DC., Leandra acutiflora (Naudin) Cogn. and Leandra melastomoides Raddi are cited in the list of endangered species for the municipality of Rio de Janeiro. An identification key is provided as well as descriptions, illustrations, comments on morphological peculiarities of species, and geographical and phenological data.

We present the floristic survey of ferns and lycophytes from the “Parque Estadual Turístico do Alto Ribeira” (PETAR), a remnant of Atlantic Rain Forest of Southeastern Brazil, in São Paulo state. Besides a complete list of species, we also provide information on habit, geographic distribution, and conservation status. Among the 237 taxa, there are 235 species, one variety and one hybrid, distributed in 29 families and 74 genera. Ferns are represented by 223 taxa, whereas the lycophytes were represented by 14. The most representative families are Polypodiaceae (31 spp.), Pteridaceae (29 spp.) and Dryopteridaceae (28 spp.). The most diverse genera are Thelypteris (23 spp.), Asplenium (19 spp.), Elaphoglossum and Blechnum (10 spp. each). Noteworthy is the presence of Ctenitis anniesii, Dicksonia sellowiana, Elaphoglossum iguapense, E. prestonii, E. strictum, Thelypteris concinna, T. araucariensis and T. hatschbachii, all of them considered as endangered species in São Paulo state.

The genus Megaelosia Miranda-Ribeiro currently comprises seven species associated with Atlantic Rain Forest of southeastern Brazil. This genus is composed of big-sized diurnal frogs that live associated to lotic streams in forests (Giaretta, et al. 1993). Five out of seven Megaelosia species have its larvae described: M. apuana Pombal, Prado & Canedo; M. boticariana Giaretta & Aguiar; M. goeldii Baumann; M. lutzae Izecksohn & Gouvêa; M. massarti De Witte (Pombal et al. 200; Giaretta & Aguiar, 1998; Lutz, 1930; Nuin, 2003; Giaretta et al, 1993).

(Floral biology and breeding system oi Psychotria tenuinervis Muell. Arg. (Rubiaceae) in the Atlantic rain forest, SE Brazil). The aim of this study was to investigate pollination biology, floral morphometry, morph ratio and breeding system oiPsychotria tenuinervis in an area of Atlantic rain forest in southeastern Brazil. Pollination biology was studied based on focal observations and the breeding system was determined using controlled crosses; data on flower production and floral morphometry were compared between the two floral morphs. Flower production by the two floral morphs was similar, with flowers being reciprocally herkogamous, diurnal and pollinated at similar frequencies, mainly by medium-sized bees. Corolla length and diameter, as well as anther length, were similar between the floral morphs, whereas stigma lobes were larger in thrums. Psychotria tenuinervis is a preferentially self- and intramorph-incompatible, non-apomitic species, with isoplethic populations. At the study site, P. tenuinervis may be considered as a typical distylous species, with reciprocal herkogamous flowers that favour intermorph pollinations and legitimate matings.
