ABSTRACT The present study aims to present the main concepts of the sugarcane straw to energy planning. Throughout the study, the subject is contextualized highlighting broader aspects of sustainability, which is considered the main driver towards agro-energy modernization. Concerning sugarcane straw, we first evaluated its availability regarding technical and economic aspects, and then it summarized the straw production chain for energy supply purposes. As a proposal to support agro-energy planning, it is presented some spatial tools that have been barely used in the Brazilian energy planning context so far. Therefore, working on straw to electricity associated with supply chain basis, we developed a conceptual model to spatially assess this bioenergy... |

A cultura do cajueiro tem uma reconhecida importancia como gerandora de ocupacao e renda na Regiao Nordeste, principalmente devido a exploracao da castanha, que se destaca como produto de exportacao; entretanto, a falta de planejamento para o desenvolvimento da cajucultura tem levado, por duas vezes, ao cultivo em areas inadequadas, resultando em indices de produtividade abaixo do esperado; o principal objetivo deste trabalho e a elaboracao de um banco de dados geografico, utilizando um Sistema de Informacoes Geograficas(SIG), para fornecer conhecimentos sobre como se distribuem os indices de producao e produtividade em areas onde ja existe a cultura do cajueiro... |

The distribution of foraging activity for female Antarctic fur seals was investigated at Cap Noir (49 degrees 07 'S, 70 degrees 45 'E), Kerguelen Island in February 1998. Eleven females were fitted with a satellite transmitter and time-depth recorder. The 2 data sets were combined in order to locate diving activity of the seals. The occurrence of fish in the diet of the seals was investigated by the identification of otoliths in 55 scats collected at the breeding colony during the study period. Oceanographic variables were measured simultaneously by direct sampling and satellite remote sensing. The mesopelagic fish community was sampled at 20 stations along 4 transects, where epipelagic trawls were conducted at night at 50 ni depth. We then investigated,... |

Marine scientists often assess habitats to understand the distribution and relative abundance of marine resources. Due to the spatial nature of habitats and associated temporal changes, however, assimilating data using traditional analytical methods is often difficult. Geographic Information Systems (GIS) are proving to be effective tools to help address problems inherent in the analysis of spatial data. GIS can be used to effectively collate, archive, display, analyze, and model spatial and temporal data. Additionally, by combining dissimilar data types, such as socio-political boundaries, bottom types, and fish distributions, for example, resource managers can use GIS to make informed management decisions. In this way, GIS provides resource managers with... |

This study describes the design and application of a stratified sampling strategy of waterbodies to assess and analyze the distribution of cyanobacteria at a regional scale (Ile-de-France, IDF). Ten groups of hydrographical zones were defined within the IDF on the basis of their anthropogenic and geomorphologic characteristics. Sampling effort (n = 50) was then randomly allocated according to the number of waterbodies in each group. This sampling strategy was tested in August 2006, using a field probe to estimate total phyto-plankton as well as cyanobacteria biomasses. The sampled waterbodies exhibited a wide range of phytoplankton (<1-375 mu g equiv.Chla L-1) and cyanobacteria biomasses (<1-278 mu g equiv. Chla L-1). 72% of the waterbodies in the... |

シカによる水稲被害が深刻化している千葉県房総半島南部において、約 350 軒の稲作農家を対象とした聞き取りアンケート調査から、シカによる水稲被 害のレベルを定量化し、それをシカの局所密度と水田周辺の景観構造により説 明する統計モデルを構築した。その結果、被害レベルはシカ密度に加え、対象 水田から半径400m 以内の景観構造により影響を受けていることが明らかにな った。具体的には、水田周囲の森林率の増加に伴い被害は大きくなること、ま たシカの高密度地域では周辺景観の林縁長が長いと被害が軽減される傾向があ ることがわかった。この空間スケールは、既往研究から示された房総のシカの 行動圏や食物の質、妊娠率が決まる空間スケールとほぼ一致していた。次に統 計モデルを用いて被害が軽度に維持されるシカ密度をシカ分布域とその周辺を 含めた地域で推定し、水稲被害のリスクマップを作成したところ、被害が軽度 に維持されるシカ密度は地域の景観構造により大きく異なることがわかった。 異質な景観構造をもつ地域では、こうしたリスクマップと現在のシカ生息密度 とを比較し、短期的な捕獲目標個体数を局所レベルで定めることで、被害防除 努力をより効率的に配分することができるだろう。 The sika deer population (Cervus nippon) in the Boso Peninsula of Chiba, central Japan, has expanded dramatically in recent decades, causing serious damage to rice crops. To predict the level of damage, we conducted approximately 350... |

Geographic information system (GIS) applied to forest analysis permit the recognition and analysis of spatial patterns of species in two and three dimensional. The aim of this study to demonstrate the efficiency of cartesian and spatial coordinates method (MCCE), method of correcting UTM coordinates of trees location in accordance with the location of field or Cartesian (X ,Y), combined with natural neighbor index (ANND) in recognition and analysis of spatial distribution patterns of four commercial timber species in forest management in Caracaraí, Roraima State, Brazil. Simulations were performed on 9 ha, divided into 100 plots of 100 m2 each. Collected data were DBH > 10 cm, commercial and total heights, cartesian coordinates (X,Y) and spatial... |

ABSTRACT An environmental zoning proposal due to the demand to develop strategies to ensure biodiversity scenarios for the remaining mixed ombrophilous forests was carried out for the Irati National Forest, a legally protected area for sustainable use located in southern Brazil. To identify land use and cover, Ikonos PSM images dated from December 2004, based on the interpretation of visual character and vectorization of orbital data were used. Qualitative and quantitative classifications identified six types of land and cover use: native forest, forestry, capoeira grass, wetland, araucaria plantation, and anthropic. The native forest relative to the mixed ombrophilous forest was the prevailing type of land cover. The environmental zoning proposal defined... |
