ESTRUTURA DA VEGETAÇÃO ARBÓREA NA MATA CILIAR DO RIBEIRÃO CLARO, MUNICÍPIO DE RIO CLARO - SP

Foram amostrados 200 indivíduos arbóreos pre­sentes na mata ciliar no ribeirão Claro. O estudo de­ monstrou a presença de 2 estratos arbóreos, com emer­gentes. A distribuição dos diâmetros na fitocenose apre­sentou maior freqüência nas classes inferiores. Foram realizados estudos de freqüência de classes de diâme­tro nas populações mais importantes

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

Seed predation of Virola bicuhyba (Schott) Warb. (Myristicaceae) in the Atlantic forest of south-eastern Brazil

Foi estudada a predação de sementes em Virola bicuhyba (Myristicaceae) em área de floresta atlântica no sudeste do Brasil, com objetivo de testar o modelo de Janzen-Connell de que a mortalidade de sementes aumenta próximo a árvore parental. Foi avaliada a predação de sementes em três diferentes distâncias da árvore mãe e para duas classes de predadores: invertebrados e vertebrados. Foram utilizadas parcelas de exclusão para vertebrados e parcelas controle abertas, distribuídas a 5, 15 e 25 m de distância do tronco de indivíduos de V. bicuhyba em frutificação. No Experimento 1 foram utilizadas 1.200 sementes e no Experimento 2, 1.440 sementes. Os dois experimentos não corroboraram o modelo de Janzen-Connell, pois a predação de sementes por invertebrados e vertebrados foi independente da distância da árvore parental. Foram verificadas altas taxas de predação de sementes, porém a predação por vertebrados foi maior do que por invertebrados nos dois experimentos, sendo esta a principal causa da mortalidade das sementes.Seed predation of Virola bicuhyba (Myristicaceae) was studied in an area of Atlantic forest in south-eastern Brazil, with the objective of testing the Janzen-Connell model. The predation of seeds was evaluated at three different distances from the parent tree for two classes of predators: invertebrates and vertebrates. The method of exclosure plots (closed plots) and open control plots was used, distributed at 5, 15 and 25 m from the trunk of each adult fruiting tree of V. bicuhyba. In Experiment 1, 1,200 seeds were used and, in Experiment 2, 1,440 seeds. Both experiments did not agree with Janzen-Connell model, as seed predation by invertebrates and vertebrates was independent of the distance from the parent tree. Seed predation rate was high, however the impact of predation by vertebrates was higher than by invertebrates, indicating that it is the main cause of seed mortality.Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES
