1. Potential and restrictions of Poincianella pyramidalis (Tul.) L. P. Queiroz as native forage in the Brazilian semi-arid region
ABSTRACT. Poincianella pyramidalis (catingueira) is a endemic plant of the Caatinga, selected by animals grazing on native pasture. With the aim of evaluating characteristics indicative of its nutritional quality, 10 plants were selected and identified, sampled at five different ages, were used to determine dry matter (DM), crude protein (CP), neutral deterg

2. La nature urbaine: dégradation quantitative et qualitative des espaces verts urbains, cas de la ville steppique de M’Sila, Algérie
Resumo O papel da natureza numa cidade que está começando a crescer em termos de extensão urbana em detrimento dos espaços verdes continua sendo um assunto pouco desenvolvido nos múltiplos estudos urbanísticos realizados na cidade de M’sila. Com efeito, o centro dessa aglomeração, denso pelas diferentes subdivisões e conjuntos habitacionais coleti

3. Water quality and anthropogenic impact in the watersheds of service reservoirs in the Brazilian semi-arid region
RESUMO A região semiárida do Brasil é caracterizada pela irregular distribuição temporal e espacial da pluviosidade que junto às ações antrópicas causam a degradação da qualidade da água. Objetivou-se neste estudo avaliar a qualidade da água em reservatórios superficiais no semiárido brasileiro face a variabilidade da precipitação e o grau d

4. Agroforestry systems, nutrients in litter and microbial activity in soils cultivated with coffee at high altitude
Agroforestry systems are an alternative option for sustainable production management. These systems contain trees that absorb nutrients from deeper layers of the soil and leaf litter that help improve the soil quality of the rough terrain in high altitude areas, which are areas extremely susceptible to environmental degradation. The aim of this study was to

5. CARACTERIZACIÓN Y CUANTIFICACIÓN DE FRAGMENTOS DE BOSQUE NATIVO, EN UN SECTOR DEL SECANO INTERIOR DE LA REGIÓN DEL MAULE, CHILE
ABSTRACT In general, the Mediterranean forests have suffered high levels of fragmentation, mainly by anthropogenic action, as result of the productive activities of agriculture and livestock, human settlements and forest plantations of fast growing exotic species, leading to loss of continuity of natural forests, and thus a decrease of biodiversity. In this

6. Recuperação de solo salino-sódico por fitorremediação com Atriplex nummularia ou aplicação de gesso. / Reclamation of saline-sodic soil by phytoremediation with Atriplex nummularia or application gypsum.
Arid and semi-arid environments may present salty soils, which hamper plant growth, being removed from productive process constituting degradation cores. Under these conditions, glycophyte plants cant growth because high levels of salts hinder their metabolism, however, for halophytes this is favorable environment and these plants may represent a key to soil

7. Degradation and detoxification of three textile Azo dyes by mixed fungal cultures from semi-arid region of Brazilian Northeast
The aim of this work was to study the degradation and detoxification of three textile azo dyes (Reactive Red 198, Reactive Red 141 and Reactive Blue 214) by mixed fungal cultures from semi-arid region of Brazilian Northeast. Sediment samples of twenty water reservoirs in the surroundings of Serra da Capivara National Park, area of environmental preservation

8. AVALIAÇÃO DAS POTENCIALIDADES DAS TERRAS, ADEQUAÇÃO DO USO DAS TERRAS E INDICADORES DE QUALIDADE DOS SOLOS: subsídios para o planejamento conservacionista no perímetro irrigado de Mirorós (Ba). / EVALUATION OF THE LAND POTENTIALS, LAND USE ADEQUACY AND SOIL QUALITY INDICATORS: subsidies for conservationist planning in the irrigated Perimeter of Mirorós (Ba).
The practice of irrigated agriculture represents an increase of agricultural productivity, especially for areas with water deficit. Lands are frequently characterized erroneously which, coupled with lacking conservation measures, imposes serious consequences for the environment. In reality, any land use and intensive soil management when carried out unsustai

This study aims to examine the implementation and effectiveness of the Natural Monument of the monoliths of Quixada, conservation area located in the backwoods of Central Ceará. For the analysis of effectiveness was conducted an integrated analysis geoenvironmental, trying to identify the environmental systems and their main strengths and limitations. Was a

10. Aplicação e análise de metodologia de deterioração ambiental em micro-bacia do seridó potiguar / Implementation and analysis methodology of environmental degradation in micro-basin of Seridó potiguar
No mundo contemporâneo a deterioração das áreas semi-áridas do planeta tem sido foco da atenção da mídia e da comunidade científica. O Brasil possuindo um semi-árido, considerado o mais problemático do mundo, seja por pressões dos fatores físicos, seja como conseqüência de políticas públicas equivocadas, tem ao longo do tempo sido vítima da

11. Parâmetros indicativos do processo de salinização em rios urbanos do semi-árido brasileiro
This study examined the spatial and temporal variations of six important parameters of the salt accumulation process in water samples collected along section urban of Contas River. The Na+, K+, Ca2+ and Mg2+ concentrations were determined by FAAS. The conductivity, total dissolved solids, Na+ and Ca2+ presented the largest seasonal and spatial variations in

12. Consequências climáticas da desertificação parcial do semi-árido do nordeste brasileiro / Climatic consequences of gradual desertification of the semi-arid region of northeast Brazil
The climatic impacts of partial desertification in the Semi-arid region of Northeast Brazil (SANEB) are evaluated by regional model (MM5) simulations. Maps of natural vegetation (without human influence; SANEB covered predominantly by dry shrubland known as caatinga), total desertification (replacement of the natural vegetation by desert in SANEB), partial d
