Dinoflagelles toxiques sur les cotes francaises pendant l'ete 1983. Perturbations des ecosystemes en baie de Vilaine. Analyse des successions phytoplanctoniques precedant l'apparition d'un dinoflagelle toxique.

Autores: Pierre, Marie-josé; Lassus, Patrick.
The incidence of phytoplankton communities sequences on toxic dinoflagellate Dinophysis acuminata occurrence was studied in the course of summer 1983, in Vilaine Bay. Despite difficulties in finding obvious relationship between occurrences of that species in the fields and preceding species it nevertheless may be emphasized: 1) a real perturbation of ecosystems is noticeable (rank-frequency diagrams); 2) the amount of sampling stations might be reduced in so far as representative stations are maintained.

Spatial organisation of macrozoobenthic communities in response to environmental factors in a coastal lagoon of the NW African coast (Merja Zerga, Morocco)
Provedor de dados: 5
Autores: Bazairi, H; Bayed, A; Glemarec, M; Hily, C.
Merja Zerga lagoon, located on the Moroccan Atlantic coast, is a site of international value (Ramsar Site) in terms of its ornithological diversity. However, the lagoon is heavily exploited for its clams and fishes. In an effort to further understanding of lagoon ecosystems, and thus to facilitate the management and conservation of their resources, an ecological survey of its benthic component was carried out. Benthos is a valuable food source for birds, fishes and humans. This work involved identifying the macrozoobenthic communities in the lagoon and assessing their spatial distribution. The study was based on monthly sampling of the intertidal zone and seasonal sampling in subtidal zone, over a one-year period. In the intertidal zone, salinity and...

Macrophytes of Lake Victoria and succession after invasion of Water Hyacinth
Provedor de dados: 20
Autores: Omondi, R.; Kusewa, Mwende.
The distribution of Lake Victoria (Kenya) macrophytes is described. Succession of macrophytes in the lake became more dramatic and dynamic after invasion of water hyacinth. The weed pushes and smothers other free-floating macrophytes like Pistia stratiotes. It then provides substrates for the emergent Vossia cuspidata, which later reduces its population by competition for light and nutrients. The noxious weed is believed to have led to extinction of Azolla nilotica in the lake.

Succesional patterns on fouling plates in the Bay of Santa Marta, Colombian Caribbean
Provedor de dados: 20
Autores: García, C.B.; Salzwedel, H.
Successional progress was followed ¡n fouling communities, developing under tropical conditions. Primary succession was simulated by immersing asbestos plates. The plates represent small, discrete, isolated parts of habitat. According with expectations, a trend of increasing space dominancy by colonial forms was detected as succession progressed. High within-habitat diversity but global persistency was confirmed f or this tropical system. Several mechanisms of succession were found to operate simultaneously. In this Caribbean fouling system the strong self-replacement tendencies of solitary forms and the low recruitment and growth rates of the potential space dominants (colonial forms) were mostly responsible for the successional patterns observed.

Forensic Entomology research has been concentrated in only a few localities of the "Cerrado" vegetation, the Brazilian Savannah. The present study had, as its objective, an examination of the diversity of arthropod fauna associated with the carcasses of Sus scrofa (Linnaeus) in this biome. The study was conducted during the dry and humid periods in two Cerrado vegetation profiles of the State of Minas Gerais. The decaying process was slower and greater quantities of arthropods were collected during the dry period. Insects represented 99% of 161,116 arthropods collected. The majority of these were Diptera (80.2%) and Coleoptera (8.8%). The entomofauna belong to 85 families and at least 212 species. Diptera were represented by 31 families and at least 132...

Floristic evolution in an agroforestry system cultivation in Southern Brazil
Provedor de dados: 42
Autores: SILVA,LUÍS C.R.; MACHADO,SEBASTIÃO A.; GALVÃO,FRANKLIN; FIGUEIREDO FILHO,AFONSO.
ABSTRACT Bracatinga (Mimosa scabrella Bentham) is an important pioneer tree species in Ombrophylous Mixed Forest of Brazil and is widely used as an energy source. In traditional agroforestry systems, regeneration is induced by fire, then pure and dense stands known as bracatinga stands (bracatingais) are formed. In the first year, annual crops are intercalated with the seedlings. At that time the seedlings are thinned, then the stands remain at a fallow period and cut at seven years old. The species is very important mainly for small landowners. We studied the understory species that occur naturally during the succession over several years in order to manage them rationally in the future and maintain the natural vegetation over time. Three to 20 year-old...

Diversity, community structure and conservation status of an Atlantic Forest fragment in Rio de Janeiro State, Brazil
Provedor de dados: 49
Autores: Cysneiros,Vinicius Costa; Mendonça-Junior,Joaquim de Oliveira; Gaui,Tatiana Dias; Braz,Denise Monte.
The State of Rio de Janeiro still holds unknown portions of the Atlantic Forest, which represent gaps in the knowledge of this ecosystem. Paracambi and neighbor municipal districts comprise a vast stretch of virtually unknown forest that makes up part of the Serra do Mar biodiversity corridor. The following study describes the tree community structure in a stretch of the ombrophilous Atlantic Forest, in the Parque Natural Municipal do Curió (Curio MNP), Paracambi, Rio de Janeiro, which serves as the basis to evaluate species diversity and conservation status. The altitudes in the area ranges from 100 to 690 m and the climate varies from mild subtropical to tropical hot and humid. Forty plots (10x10m) were randomly placed along the area, where all the stems...
