Provedor de dados: Revista Brasileira de Entomologia
Autores: Urso-Guimarães,Maria Virginia; Castello,Ana Carolina Devides; Kataoka,Eric Yasuo; Koch,Ingrid.
ABSTRACT In this paper we performed a study of occurrence and characterization of entomogen galls from natural vegetation areas in Mato Grosso do Sul. We surveyed natural areas of four biomes from Mato Grosso do Sul State: Pantanal (Corumbá), Atlantic Forest (Bodoquena), Cerrado (Aquidauana), and Chaco (Porto Murtinho). We identified 186 morphotypes of galls in 115 host plant species from 35 families and 73 genera. The richest families were Fabaceae (N = 34), Sapindaceae (N = 24), Bignoniaceae (N = 17), and Myrtaceae (N = 15). Fifty morphotypes of insects (27%) were found in galls of 38 host plants, 78% of which belongs to Diptera, 10% to Hymenoptera, and the other 12% are divided among Hemiptera, Thysanoptera, Coleoptera, and Lepidoptera. In this study,...

Pathways affect vegetation structure and composition in the Atlantic Forest in southeastern Brazil
Provedor de dados: Acta Botanica Brasilica
Autores: Silva,Bruna Gonçalves da; Castello,Ana Carolina Devides; Koch,Ingrid; Silva,Wesley Rodrigues.
ABSTRACT Although impacts generated by gaps can affect vegetation, few studies have addressed these impacts in the Atlantic Forest. Our aim was to investigate the effects of pathways of varying widths on vegetation structure and composition, considering dispersal syndromes, diversity, life forms, successional categories and threatened and exotic species occurrence in the Atlantic Forest. We studied three pathways with widths of 2, 10 and 20 m, intersecting a protected area in southeastern Brazil. To assess edge effects, plots were established adjacent to paths (edge) and 35 m from the edge (neighborhood), and in a control area without pathways. Wider pathways (10 and 20 m) exhibited reduced tree height and diameter, high liana density, exotic species, and...

Reestablishment, new records, and a key for the species of Aspidosperma (Apocynaceae) from the Brazilian Amazon
Provedor de dados: Acta Botanica Brasilica
Autores: Pereira,Andreza Stephanie de Souza; Castello,Ana Carolina Devides; Simões,André Olmos; Koch,Ingrid.
ABSTRACT As a result of systematic study of the Neotropical genus Aspidosperma (Apocynaceae), we reestablish the species A. centrale and A. duckei, and report A. steinbachii and A. tambopatense as new records for Brazil. We provide taxonomic descriptions of these species along with plates, distribution maps, and information on their conservation status, habitat and phenology. We also provide an identification key for all the species of Aspidosperma from the Brazilian Amazon.

Host specificity and experimental assessment of the early establishment of the mistletoe Phoradendron crassifolium (Pohl ex DC.) Eichler (Santalaceae) in a fragment of Atlantic Forest in southeast Brazil
Provedor de dados: Acta Botanica Brasilica
Autores: Messias,Patrícia Aparecida; Vidal Jr.,João de Deus; Koch,Ingrid; Christianini,Alexander V.
Mistletoe establishment relies heavily on a seed reaching a proper host plant. Small frugivorous birds usually disperse large numbers of mistletoe seeds. However, in the field, mistletoes are absent from some potential available hosts. We investigated whether the mistletoe Phoradendron crassifolium has some preferences for specific host trees in a fragment of Atlantic Forest in southeast Brazil. We surveyed 397 tree individuals of 50 species within 25 families. Seven of those species (14%) bore P. crassifolium infections. Although prevalence at the individual level was low (11.6%), there were marked deviations in infection levels among species and families. Most (87%) of the infections (40 of 46) occurred in species belonging to the families Anacardiaceae...

Paleodistribution of Neotropical species of Erythroxylum (Erythroxylaceae) in humid and dry environments
Provedor de dados: Acta Botanica Brasilica
Autores: Cordeiro,Luciana Silva; Araújo,Francisca Soares de; Koch,Ingrid; Simões,André Olmos; Martins,Fernando Roberto; Loiola,Maria Iracema Bezerra.
ABSTRACT Variation in environmental conditions during the Quaternary period served as important filters for the maintenance of vegetation types and for determining the composition of the current biota. We analyzed oscillations in the distributions of different vegetation types in Brazil during the Quaternary period using species of the genus Erythroxylum (Erythroxylaceae) because of the vast heterogeneity of habitats in which they occur. We hypothesized that it would be possible to observe geographically distinct distribution patterns of species of Erythroxylum as a result of the climate changes that occurred during the last glacial maximum (LGM) and in the last interglacial period (LIG) of the Pleistocene. We used bioclimatic variables to elaborate...

O projeto Flora Fanerogâmica do Estado de São Paulo tem se dedicado a inventariar a flora paulistana há quase 20 anos. Conta com a atuação de mais de 200 colaboradores, a maioria do próprio estado, além de pesquisadores de outros estados e do exterior. Desde 2001, foram publicados sete volumes com as monografias de 151 famílias, contendo 3.237 espécies em 722 gêneros. Este projeto foi o ponto de partida para o conhecimento da diversidade das espécies de espermatófitas do estado de São Paulo. A apresentação do checklist neste momento é oportuna por constituir a produção de uma listagem das espécies com identificações certificadas pelos especialistas, além de conter a referência de uma coleção de herbário para a maior parte dos táxons (material-testemunho)...
