Abundance and diversity of soil mites of fragmented habitats in a biosphere reserve in Southern Nigeria
Provedor de dados: 86
Autores: BADEJO,MOSADOLUWA ADETOLA; OLA-ADAMS,BUNY AMIN.
Soil samples were collected from the top 7.5 cm of soil in a Strict Natural Reserve (SNR), a surrounding buffer zone, a cassava farm and matured plantations of Gmelina, teak, and pine, so as to determine if plantation establishment and intensive cultivation affect the density and diversity of soil mites. Altogether, 41 taxonomic groups of mites were identified. The diversity and densities of mites in within the SNR, the buffer zone and the Gmelina were more than the diversity and densities in the cassava farm, teak and pine plantations. Each plantation had its own unique community structure which was different from the community structure in the SNR plot. The SNR plot and Gmelina were dominated by detritivorous cryptostigmatid mites unlike teak and pine...

Les "marées vertes" en Bretagne, la responsabilité du nitrate
Provedor de dados: 5
Autores: Menesguen, Alain.
Since 25 years, an increasing number of beaches and coves along the Britanny coast are invaded from spring until autumn by proliferating green macroalgae (free ulvae, fixed enteromorphae). This typical case of eutrophication, which has been well studied in the bays of Saint-Brieuc, Lannion, Douarnenez and Brest, could be explained by the conjunction of a natural containment of shallow water masses with a recent enrichment of them by nitrate river loadings. In the naturally confined sites, field measurements of summer biomass showed a good correlation with the spring nitrate river loadings ; furthermore, the summer rarefaction of these loadings explains the fall of the nitrogen content of the ulvae, which induces the summer stop of the algal growth.  The...

Development and evolution of forms of cooperation in Hungarian agriculture during the 20th century
Provedor de dados: 31
Autores: Trojan,   Szabolcs; Csizmadia,   Mate; Csordas S.,   Tibor.
The forms of cooperation which are common in Hungarian agriculture are fundamentally different from those characteristic of Western Europe. This was caused principally by the collectivization process implemented after the Second World War. Our paper presents the various forms of cooperation found in Hungarian agriculture and food industry, form the beginning of the 20th century to our present days. The socialist reorganization of Hungarian agriculture resulted in close ties between the entities engaged in agriculture and food industry, creating straightforward product chains and enabling the modernization of production processes. Co-ops and state farms, as well as production systems and agroindustrial corporations employed state-of-the-art technologies of...
