Provedor de dados: 7
Autores: Allen, Jeffery; Clemson University; jeff@strom.clemson.edu; Lu, Kang; Clemson University; klu@strom.clemson.edu.
The complexity of urban systems makes it difficult to adequately address their changes using a model based on a single approach. In this research, we developed a GIS-based integrated approach to modeling and prediction of urban growth in terms of land use change. The model was built upon a binomial logistic framework, coupled with a rule-based suitability module and focus group involvement, and is designed to predict land transition probabilities and simulate urban growth under different scenarios. The model was calibrated in the Charleston region of South Carolina through a GIS-facilitated participatory process involving both statistical assessment and human evaluation. The model achieved high overall success rates, although its predictive power varied...

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...

The Artificial Neural Networks (ANNs) are mathematical models method capable of estimating non-linear response plans. The advantage of these models is to present different responses of the statistical models. Thus, the objective of this study was to develop and to test ANNs for estimating rainfall erosivity index (EI30) as a function of the geographical location for the state of Rio de Janeiro, Brazil and generating a thematic visualization map. The characteristics of latitude, longitude e altitude using ANNs were acceptable to estimating EI30 and allowing visualization of the space variability of EI30. Thus, ANN is a potential option for the estimate of climatic variables in substitution to the traditional methods of interpolation.

Autores: Guinet, Christophe; Dubroca, L; Lea, Ma; Goldsworthy, S; Cherel, Yan; Duhamel, Guy; Bonadonna, F; Donnay, Jp.
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,...

Applications of Geographic Information Systems (GIS) to habitat assessment and marine resource management
Provedor de dados: 5
Autores: Stanbury, Kb; Starr, Rm.
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...

Provedor de dados: 5
Autores: Catherine, A; Troussellier, Marc; Bernard, C.
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 (&lt;1-375 mu g equiv.Chla L-1) and cyanobacteria biomasses (&lt;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...

Autores: Hartz,Sandra M.; Rocha,Elise A.; Brum,Fernanda T.; Luza,André L.; F.R.,Taís de; Becker,Fernando G.
ABSTRACT In this study we investigated the influence of landscape variables on the alpha taxonomic and functional diversity of fish communities in coastal lakes. We built an analytical framework that included possible causal connections among variables, which we analyzed using path analysis. We obtained landscape metrics for the area, shape and connectivity (estuary connectivity and primary connectivity to neighboring lakes) of 37 coastal lakes in the Tramandaí River Basin. We collected fish data from 49 species using standardized sampling with gillnets and obtained a set of traits related to dispersal abilities and food acquisition. The model that best explained the taxonomic diversity and functional richness took into account the shape of the lakes....
