A methodological approach to potential vegetation modeling using GIS techniques and phytosociological expert-knowledge: application to mainland Portugal IPB - Escola Superior Agrária
Capelo, J.; Mesquita, Sandra; Costa, José C.; Ribeiro, Silvia; Arsénio, Pedro; Neto, Carlos; Monteiro-Henriques, T.; Aguiar, Carlos; Honrado, João; Espírito-Santo, Dalila; Lousã, Mário.
An attempt to obtain a consistent spatial model of natural potential vegetation (NPV) for the mainland Portuguese territory is reported. Spatial modeling procedures performed in a Geographic Information System (GIS) environment, aimed to operationalize phytosociological expert-knowledge about the putative distribution of potential zona1 forest communities dominant in the Portuguese continental territories. The paradigm for NPV assumed was that of RIVAS-MARTINEZ (1976) and RIVAS-MARTINEZ et al. (1999), which presupposes, for a given territory, a univocal correspondence between a uniform combination of bioclimatic stage and lithology given a biogeographical context, and a unique successional sequence leading to a single climax community (i. e. a vegetation...

A methodological proposal for quantifying environmental compensation through the spatial analysis of vulnerability indicators. Repositório Alice
TORRESAN, F. E.; LORANDI, R..
The aim of this work was to propose a methodology for quantifying the environmental compensation through the spatial analysis of vulnerability indicators. A case study was applied for the analysis of sand extraction enterprises, in the region of Descalvado and Analândia, inland of São Paulo State, Brazil. Environmental vulnerability scores were attributed for the indicators related to erosion, hydrological resources and biodiversity loss. This methodological proposal allowed analyzing the local alternatives of certain enterprise with the objective of reducing impacts and at the same time reducing the costs of environmental compensation. The application of the methodology significantly reduced the subjectivity degree usually associated to the most of the...

A regional analysis of weather mediated competition between a parasitoid and a coccinellid predator of oleander scale Neotropical Entomology
Gutierrez,Andrew P.; Pizzamiglio,Marina A..
The regulation of an asexual population of the oleander scale [Aspidiotus nerii Bouchè (Hemiptera: Diaspididae)] on California bay tree [Umbellularia californica (Hopk. & Arn.) Nut.] by two natural enemies; an idiobiont, ectoparasitoid Aphytis chilensis Howard (Hymenoptera: Aphelinidae) and a coccinellid predator (Rhysobius lophanthae (Blaisd.) (Coleoptera: Coccinellidae), was examined using a general weather-driven, tri-trophic, physiologically based age-mass structured demographic model. The model is of intermediate complexity and was parameterized using extensive laboratory data and field observations from Albany, CA. Temperature-dependent physiological indices were estimated from the laboratory data and used to scale per capita growth,...

A Simple Non-Parametric Gis Model For Predicting Species Distribution: Endemic Birds In Bioko Island OceanDocs
Fa, J.E.; Lenton, S.M.; Del Val, J.P..
Species mapping is a useful conservation tool for predicting patterns of biological diversity, or identifying geographical areas of conservation significance. Mapping can also improve our understanding of the appropriateness of habitat areas for individual species. We developed a new model, PREDICT, for mapping habitat suitability of plant and animal species from incomplete field survey data. PREDICT is a statistical program written for use within a GIS (geographic information system). It produces images and statistics that assess the potential of unstudied areas for wildlife for which presence/absence data and basic habitat information are available. Suitability for a target species is determined within surveyed and non-surveyed squares by a form of...

Activity patterns, home-range size, and habitat utilization of Sarpa salpa (Teleostei : Sparidae) in the Mediterranean Sea ArchiMer
Jadot, Catherine; Donnay, A; Acolas, M; Cornet, Y; Begout, Marie-laure.
Acoustic telemetry was used to record diel movement and habitat utilization of the salema (Sarpa salpa) (Teleostei: Sparidae) during three consecutive summers from 2000 to 2002 in the Calvi and Achiarina bays of Corsica in the Mediterranean Sea. A total of 18 fish was equipped with acoustic transmitters inserted in the body cavity, 13 were tracked in the Bay of Calvi (275 mm +/- 26.9 L-F), and 5 in Achiarina Bay (260 mm +/- 33.6 LF). Two different systems were used to track the fish. The one used in the Bay of Calvi was a manual receiver and a directional hydrophone. The second system, used in Achiarina Bay, was a radioacoustic-positioning (RAP) system that continuously monitored the movements of the fish. Fish positions were put in a geographic...

Agricultural land use and cover change in the Cerrado/Amazon ecotone: A case study of the upper Teles Pires River basin Acta Amazonica
ZAIATZ,Ana Paula Sousa Rodrigues; ZOLIN,Cornélio Alberto; VENDRUSCULO,Laurimar Goncalves; LOPES,Tarcio Rocha; PAULINO,Janaina.
ABSTRACT The upper Teles Pires River basin is a key hydrological resource for the state of Mato Grosso, but has suffered rapid land use and cover change. The basin includes areas of Cerrado biome, as well as transitional areas between the Amazon and Cerrado vegetation types, with intensive large-scale agriculture widely-spread throughout the region. The objective of this study was to explore the spatial and temporal dynamics of land use and cover change from 1986 to 2014 in the upper Teles Pires basin using remote sensing and GIS techniques. TM (Thematic Mapper) and TIRS (Thermal Infrared Sensor) sensor images aboard the Landsat 5 and Landsat 8, respectively, were employed for supervised classification using the “Classification Workflow” in ENVI 5.0. To...

An entomological surveillance system based on open spatial information for participative dengue control Anais da ABC (AABC)
Regis,Leda; Souza,Wayner V.; Furtado,André F.; Fonseca,Cláudio D.; Silveira Jr.,José C.; Ribeiro Jr.,Paulo J.; Melo-Santos,Maria Alice V.; Carvalho,Marilia S.; Monteiro,Antonio M.V..
Aedes aegypti is a very efficient disseminator of human pathogens. This condition is the result of evolutionary adaptations to frequent haematophagy, as well as to the colonization of countless types of habitats associated with environmental and cultural factors that favor the proliferation of this mosquito in urban ecosystems. Studies using sensitive methods of monitoring demonstrate that the methods of surveillance used in the Brazilian program do not show the high degrees of the infestation of cities by this vector. To increase the capacity of the health sector, new tools are needed to the practice of surveillance, which incorporate aspects of the vector, place and human population. We describe here the SMCP-Aedes - Monitoring System and Population...

An example of GIS potentiality for coastal zone management: preselection of submerged oyster culture areas near Marennes-Oleron (France) ArchiMer
Durand, H.; Guillaumont, Brigitte; Loarer, Ronan; Loubersac, Lionel; Heral, Maurice; Prou, Jean.
The Charente Maritime coast, in central western France, is the most important area for oyster and mussel production in Europe. High density, in this restricted intertidal area, induces low growing rate and socio-economic difficulties. One of the possible solutions is to shift some oysters from intertidal area to submerged areas. Bathymetry, sedimentology, hydrodynamism, fisheries and administrative rules are some conditions which are considered to establish the better selection of potential zone. The successive steps of setting up the prototype of GIS are presented: digitized traditional data from charts, extracted data from grid models (hydrodynmaic model), merging of thematic covers, proposal of favorable areas. The results are discussed especially on...

Are EU spatial ex ante coexistence regulations proportional? AgEcon
Demont, Matty; Daems, W.; Dillen, Koen; Mathijs, Erik; Sausse, C.; Tollens, Eric.
The EU is currently struggling to implement coherent coexistence regulations on genetically modified (GM) and non-GM crops in all member states. While it stresses that any approach needs to be “proportionate to the aim of achieving coexistence”, very few studies have actually attempted to assess whether the proposed spatial ex ante coexistence regulations (SEACERs) satisfy this proportionality condition. In this article, we define proportionality as a functional relationship which is weakly increasing in the incentives for coexistence. We propose a spatial framework based on an existing landscape and introduce the new concept of shadow factor as a measure for the opportunity costs induced by SEACERs. This enables comparing the proportionality of (i) rigid...

Aspectos generales sobre la estructura térmica superficial del mar, de la zona comprendida entre el golfo de Penas y la boca occidental del estrecho de Magallanes OceanDocs
Boré, D.; Barbieri, M.A.; Catasti, V..
This study was carried out within the Project Cimar-Fiordo 2. The general objective was to describe the sea surface temperature in the zone between 46º LS and 52º LS, and from the 73º 52’ LW to the 76º 30’ LW, considering the channel and fjord zone. The analysis was based on satellite images of sea surface temperature. The images used came from the AVHRR radiometer of the NOAA satellite, from the year 1995 to 1998. The cartographic representation and the analysis of the seasonal variability of the sea surface temperature was made using the software of the Geographical Information System (GIS), named IDRISI. The zone was with clouds during all the period of study, mainly in autumn. With the available images it was possible to observe a big difference...

Assessment of agricultural land-use change for helping sustainable land management and landscape development Inra
Choisis, J.P.; Thévenet, C.; Gout, J.; Ladet, S.; Sheeren, D.; Gibon, A..
Agriculture is nowadays expected to adopt “multifunctional” land use practice as a contribution to sustainable development of rural areas. We started a participatory research study in the Coteaux de Gascogne (France) to prospect local paths for agricultural systems contribution to landusesustainability. The area considered is a study-site of the Long term Ecosystem Research network.Our first common objective is to understand how family-farm dynamics contribute to land-use change at the landscape level. We started therefore a spatially-explicit and exhaustive study of agricultural land use and its change since the 1950s at a reference area of limited size (4 villages). The method consists in survey at every farmer using land in the area using both a...

Assessment of heavy metals in soils of a vineyard region with the use of principal component analysis Scientia Agricola
Valladares,Gustavo Souza; Camargo,Otávio Antônio de; Carvalho,José Ruy Porto de; Silva,Alessandra Maria Cia.
Agricultural management with chemicals may contaminate the soil with heavy metals. The objective of this study was to apply Principal Component Analysis and geoprocessing techniques to identify the origin of the metals Cu, Fe, Mn, Zn, Ni, Pb, Cr and Cd as potential contaminants of agricultural soils. The study was developed in an area of vineyard cultivation in the State of São Paulo, Brazil. Soil samples were collected and GPS located under different uses and coverings. The metal concentrations in the soils were determined using the DTPA method. The Cu and Zn content was considered high in most of the samples, and was larger in the areas cultivated with vineyards that had been under the application of fungicides for several decades. The concentrations of...
