Mediterranean ecosystems have been shaped by a history of human and ecological disturbances. Understanding the dynamics of these social-ecological systems requires an understanding of how human and ecological factors interact. In this study, we assess the combined role of management practices and biophysical variables, i.e., wildfire and topography, to explain patterns of tree persistence in a cork oak  (Quercus suber L.) landscape of southern Portugal. We used face-to-face interviews with landowners to identify the management practices and the incentives that motivated them. We used aerial photographs and a Geographic Information System (GIS) to classify vegetation patch-type transitions over a period of 45 years (1958-2002) and logistic regression to...

Methodological adaptation for nematodes extration in forest soils of the southern Mata Atlântica
Provedor de dados: 86
Autores: Moser,Thomas; Frankenbach,Silja.
The objective of this work was to clarify whether the method to extract nematodes from European soils is suitable for forest soils and litter in the eastern of Paraná state, Brazil, and whether nematode abundance differs between sites with different ecosystems and levels of human interference. The study sites were situated in the coastal area of the Serra do Mar, near the town of Antonina, in Eastern Paraná, Brazil. Cobb's sieving and decanting method was more appropriate than ISO method, since extraction efficiency was higher and intra-sample variability was significantly lower. In order to achieve an extraction efficiency higher than 90%, Cobb's method was modified. For the extraction of nematodes from litter, the Baermann funnel, with an extraction time...

The Allelopathic Effect of Eucalyptus Leaf Extract on Grass Forage Seed
Provedor de dados: 87
Autores: Carvalho,F.P.; Melo,C.A.D.; Machado,M.S.; Dias,D.C.F.S.; Alvarenga,E.M.
This study aimed to evaluate the allelopathic effect of various concentrations of an aqueous extract of eucalyptus leaves on Urochloa decumbens and Panicum maximum seeds. The extract was prepared from Eucalyptus urograndis leaves that were milled and mixed with distilled water in a 1:9 milled leaves: water ratio to obtain an extract with a defined concentration of 100%. In addition, dilutions of 50%, 25% and 12.5% were prepared, and a 0% dilution was used as a control. The experiment followed a completely randomized design, with four replicates, each of 50 seeds of U. decumbens and 50 seeds of P. maximum, arranged on filter paper moistened with each concentration of extract in a Gerbox plastic box. The results demonstrated the allelopathic potential of E....

Vegetative and productive aspects of organically grown coffee cultivars under shaded and unshaded systems
Provedor de dados: 63
Autores: Ricci,Marta dos Santos Freire; Rouws,Janaina Ribeiro Costa; Oliveira,Nelson Geraldo de; Rodrigues,Marinete Bezerra.
Although Coffea arabica species has its origin in the African understories, there is great resistance on the part of the Brazilian producers for growing this species under agroforestry systems as they fear that shading reduces production. This study aimed at evaluating some vegetative traits and the productivity of organically grown coffee (Coffea arabica L.) cultivars under shaded and unshaded systems. Twelve treatments consisting of two cultivation systems (shaded and unshaded) and six coffee cultivars were arranged in randomized blocks with four replicates, in a split-plot scheme. Shading was provided by banana (Musa sp.) and coral bean plants (Erythrinaverna). Shading delayed fruit maturation. Late maturation cultivars, such as the Icatu and the Obatã,...

Improvement of the soil quality under intercropped conilon coffee (Coffea canephora P.) in the coastal tablelands of Southeast Brazil
Provedor de dados: 109
Autores: Soares de Souza,Gustavo; Thiengo,Cássio Carlette; de Assis Silva,Samuel; Armani Borghi,Edinei José.
Abstract The objective of this study was to evaluate the physical- hydrological and chemical properties and organic carbon stock of soil under intercropped conilon coffee (Coffea canephora P.) and in full sun in the coastal tablelands of Espírito Santo, Brazil. The treatments evaluated were coffee intercropped with rubber tree (CR) and in full sun (FS) in the area 1; coffee intercropped with papaya (CP) and in full sun (FS) in the area 2; coffee intercropped with coconut (CC), in full sun (FS), and an area of native vegetation (NV) in the area 3. The physical and chemical properties of the soil and its organic carbon stocks were measured in layers of 0-0.4 m. In area 1, CR showed lower soil bulk density and temperature, and higher total porosity and...

Seasonal dynamics of arbuscular mycorrhizal fungi in plants of Theobroma grandiflorum Schum and Paullinia cupana Mart. of aN agroforestry system in Central Amazonia, Amazonas State, Brazil
Provedor de dados: 58
Autores: Oliveira,Arlem Nascimento de; Oliveira,Luiz Antonio de.
The seasonal dynamics of Arbuscular Mycorrhizal Fungi (AMF) was investigated in the rhizosphere of two fruit species in a terra firme (upland) ecosystem in Central Amazonia. Two host species (Theobroma grandiflorum and Paullinia cupana) and nine sampling months (August, September and December/1998, February, April, May and December/1999, February and May/2000) were studied in a completely randomized design, with five replications, set in a 2 x 9 factorial experiment. Soil (0-20 cm depth) and root samples were collected between August 1998 and May 2000. The mean percent colonization of AMF for both species reached maximal values in February and May 2000 (rainy season). In April and May 1999, February and May 2000 (rainy season) the highest AMF spore numbers...
