Measurement of above-ground plant biomass, forage availability and grazing impact by combining satellite image processing and field survey in a dry area of north-eastern Syria
Provedor de dados: 19
Autores: Hirata, Masahiro; Koga, N; Shinjo, H; Fujita, H; Gintzburger, G; Ishida, J; Miyazaki, A.
Field survey and satellite image processing methods were used to estimate the total available forage over an area of 95 034 ha in north-eastern Syria, and to assess grazing impact on the area. The above-ground plant biomass was measured by a quadrat method at three sites in each of eight vegetation classes. Available forage was measured by excluding woody parts of shrubs from the whole aerial plant parts. The total above-ground plant biomass and available forage were estimated by extrapolating the measured point data to the whole target area using classified vegetation data by satellite image processing. Grazing impact was assessed by calculating the differences between the total available forage at the end of growing season and the end of dry season. The...

Estrutura sinusial dos componentes herbáceo e arbustivo de uma floresta costeira subtropical
Provedor de dados: 88
Autores: MÜLLER,SANDRA CRISTINA; WAECHTER,JORGE LUIZ.
As sinúsias herbáceas e arbustivas são componentes de comunidades florestais pouco pesquisados nas regiões tropicais e subtropicais. Neste trabalho foram estudadas a composição florística e a estrutura fitossociológica destas sinúsias em uma floresta arenosa (restinga) da Planície Costeira do Rio Grande do Sul, Brasil. Os dados fitossociológicos foram obtidos em 30 parcelas de 2 x 2 m. Em cada parcela anotou-se a presença e a altura máxima das espécies herbáceas e arbutivas, e a cobertura foi estimada pela escala de Causton. A composição florística total da área compreende 61 espécies, 52 gêneros e 33 famílias. As famílias que apresentaram mais de duas espécies foram: Poaceae, Commelinaceae, Orchidaceae, Piperaceae, Rubiaceae e Asteraceae. As formas de...

Floristic composition and similarity analysis of an Atlantic rain forest fragment in Cananéia, São Paulo State, Brazil
Provedor de dados: 88
Autores: Urbanetz,Catia; Tamashiro,Jorge Yoshio; Kinoshita,Luiza Sumiko.
The aim of this study is to investigate the floristic composition of an Atlantic rain forest fragment located in Cananéia, São Paulo, Brazil, and to contribute to the knowledge on Atlantic forest through the comparative analysis of this and other floristic surveys both on the southern and southeastern Brazil, in different soil and relief types. We surveyed 215 species in 132 genera and 51 families. Classification and ordination analysis were applied to a binary matrix in order to analyze the similarity among 24 surveys, including the present one, of Atlantic forest from the south and southeast coast of Brazil. Higher floristic similarity was observed among this area and the ones where there was marine influence and more rugged relief. The surveys in areas...

Are the vegetation structure and composition of the shrubby Caatinga free from edge influence?
Provedor de dados: 39
Autores: Santos,André Maurício de Melo; Santos,Bráulio Almeida.
Edge influence, or edge effect, drives many biological changes in fragmented landscapes. This has been extensively studied in many forest ecosystems, but it remains to be described for the Brazilian Caatinga. Based on the biotic and physical conditions of the shrubby Caatinga, our prediction a priori was that this type of vegetation is free from edge influence in terms of vegetation structure and composition. We sampled shrubs, cacti and trees in twenty 200 m² plots on old edges (&gt;60 yrs old) and interior of a 690 ha fragment, partially isolated and surrounded by Opuntia ficus-indica cacti. Plant height, stem diameter at ground level, stem density, species richness and diversity were statistically equal between edge and interior habitats. Magnitude of...

Phytophagous mites (Tetranychoidea: Tetranychidae, Tenuipalpidae) from natural vegetations in Lara, Venezuela
Provedor de dados: 49
Autores: Vásquez,Carlos; Mondragón,Alcides; Dávila,Martha; Aponte,Orlando.
Phytophagous mites from natural vegetation have been scarcely studied in Venezuela. Surveys were carried out from March 2007 to November 2008 to determine diversity of phytophagous mites inhabiting in different plant taxa in Iribarren, Jiménez, Palavecino, Morán and Crespo municipalities from Lara state, Venezuela. In each sampling site, a 500 m- transect was established and the most frequent plant species were sampled. In field, 15 leaves were examined for mite presence by using hand lens. In laboratory, plant material was examined under magnification and mite morpho-species belonging to tetranychid and tenuipalpid were picked up. A total of two tenuipalpid species and eight tetranychid species were identified. Tenuipalpid mites identified were...
