Florística de lianas em um fragmento de floresta estacional semidecidual, Parque Estadual de Vassununga, Santa Rita do Passa Quatro, SP, Brasil

Embora o conhecimento sobre a florística dos fragmentos de florestas estacionais semideciduais tenha crescido nos últimos anos, ainda sabe-se pouco sobre a comunidade de lianas (lenhosas ou herbáceas) nesses fragmentos. Assim, foi realizado o levantamento florístico de lianas na gleba Maravilha, pertencente ao Parque Estadual de Vassununga (Santa Rita do Passa Quatro, SP), a fim de colaborar com o conhecimento dessa comunidade e subsidiar futuros trabalhos que envolvam essa forma de vida. A área de estudo compreende 127,08 ha, com inverno seco e temperatura média anual de 22 ºC. Para a coleta do material, percorreu-se mensalmente toda a borda do fragmento e três trilhas no interior da mata, de agosto/2002 a setembro/2003. Foram identificadas 120 espécies de lianas, pertencentes a 30 famílias e 71 gêneros, das quais 51% das espécies são volúveis, 42% apresentam gavinhas e apenas 7% são escandentes. As famílias mais representativas em número de espécies foram: Bignoniaceae (26), Malpighiaceae (14), Sapindaceae (12) e Asteraceae (9). Houve baixa similaridade florística entre as espécies de lianas presentes na gleba Maravilha em relação a outras áreas de florestas estacionais semideciduais do interior paulista.

Seed dispersal and germination of Cryptocarya moschata Nees & Martius Ex Nees, Ocotea catharinensis Mez and Endlicheria paniculata (Sprengel) Macbride (Lauraceae)

Data of seed dispersal and germination of the studied species are presented, comparing both observations from the wild and nursery. Fruits were collected from Carlos Botelho State Park (24 degrees 44' to 24 degrees 03'S, 47 degrees 46' to 48 degrees 10'W), south of São Paulo State, Brazil. O. catharinensis had low germination percentage, both in the wild and in nursery, and did not tolerate seed storage at low temperature. In nursery, diaspores with removed mesocarp of E. paniculata presented greater germination than those in entire fruits. The high levels of seedling mortality beneath mother-trees of C. moschata, when in comparison to those observed to established seedlings from diaspores dispersed by muriquis (Brachyteles arachnoides E. Geoffroy 1806, Cebidae, Primates), allied to the absence of juveniles in the understory, are in accord with the escape model of Janzen-Connel. In nursery, diaspores of C. moschata dispersed by the primates had greater germination, in smaller time, than those collected from mother-trees.

Phytosociological studies in the morro do diabo forest (Pontal do Paranapanema, SP), Brazil

Results are given of a phytosociological study of a forest located in the Morro do Diabo State Park. in the county of Teodoro Sampaio (22 degrees 31'S, 52 degrees 10'W), Pontal do Paranapanema region, state of São Paulo. The point-centered quarter method, using 300 sampling points, was used establishing 3 trails of 100 sampling points each, 10 m interdistant. All woody vegetation with a breast height diameter of 5 cm or more were samplied. Three distinct ecotopes could be identified in the forest: the lower, thc slope and the peak, which were analised separately.The families that presented the greatest numbers of genera, species and individuals were Leguminosae, Euphorbiaceae and Myrtaceae, followed by Rutaceae, Lauraceae, Meliaceae and Moracea. A total of 104 species, 85 genera and 37 families were sampled by the phytosociological survey. The relative sociological position of each plant family or species varied according to ecotope.

Discovery of the first wild population of the small red brocket deer Mazama bororo (Artiodactyla: Cervidae).

Mazama bororo was described from a few captive specimens in Brazil by cytogenetic and morphological characters. These specimens supposedly originated in the Southern Atlantic Forest; however, no wild population has been reported. This study was initiated in 1998 to investigate the presence of this species in forest remnants of the Paranapiacaba mountain range, south São Paulo State, Brazil. Five specimens were captured between 2000 and 2002. Cytogenetic analysis from blood samples confirmed its specific identification, documenting the first population of small red brocket deer at the Intervales State Park.

Ephemeroptera, Plecoptera e Trichoptera em corredeiras de riachos do Parque Estadual Intervales, Estado de São Paulo.

The fauna of Ephemeroptera, Plecoptera and Trichoptera (EPT) from Intervales State Park has been recorded since the 1990s. As a result of these sampling efforts, we present in this study a list of EPT genera in riffles from streams of Intervales State Park, São Paulo State.
