“…Benthic biomass usually reflects the production of its surrounding water since detritus not mineralized by the microbial loop in the water column are transferred to benthic organisms (POLIS et al, 1997). Marine snow is a source of microbes and microorganisms are also observed in benthic systems of the Cabo Frio upwelling region.…”

A B S T R A C TThe rising of cold water from deeper levels characterizes coastal upwelling systems. This flow makes nutrients available in the euphotic layer, which enhances phytoplankton production and growth. On the Brazilian coast, upwelling is most intense in the Cabo Frio region (RJ). The basic knowledge of this system was reviewed in accordance with concepts of biophysical interactions. The high frequency and amplitude of the prevailing winds are the main factor promoting the rise of South Atlantic Central Water, but meanders and eddies in the Brazil Current as well as local topography and coast line are also important. Upwelling events are common during spring/summer seasons. Primary biomass is exported by virtue of the water circulation and is also controlled by rapid zooplankton predation. Small pelagic fish regulate plankton growth and in their turn are preyed on by predatory fish. Sardine furnishes an important regional fish stock. Shoreline irregularities define the embayment formation of the Marine Extractive Reserve of Arraial do Cabo making it an area with evident different intensities of upwelled water that harbors high species diversity. Consequently, on a small spatial scale there are environments with tropical and subtropical features, a point to be explored as a particularity of this ecosystem. R E S U M OOs sistemas costeiros de ressurgência são caracterizados pela ascensão de águas frias que tornam os nutrientes disponíveis na camada eufótica para o crescimento e aumento da produção fitoplanctônica. No Brasil, a região do Cabo Frio (RJ) é o principal sistema de ressurgência costeira. O objetivo desse artigo foi revisar o atual conhecimento desse sistema através dos conceitos sobre interações biofísicas. A ascensão da Água Central do Atlântico Sul ocorre devido à alta frequência e amplitude dos ventos, à presença de meandros e vórtices na Corrente do Brasil, além da topografia local e da linha de costa. Os eventos de ressurgência são comuns durante os períodos de primavera/verão e a biomassa primária é exportada devido à circulação da água, sendo também controlada pela rápida predação zooplanctônica. Os pequenos peixes pelágicos regulam o crescimento do plâncton e são consumidos pelos peixes predadores, resultando em um importante estoque pesqueiro regional. A irregularidade da costa define as enseadas do Cabo Frio, na Reserva Extrativista Marinha do Arraial do Cabo, apresentando distintas influências das águas ressurgidas e resultando em grande diversidade de espécies. Consequentemente, ambientes com características tropicais e subtropicais são observados dentro de uma pequena escala espacial, o que constitui uma particularidade desse ecossistema.

“…De manière parallèle, au cours des 15 dernières années, les travaux menés en écologie du paysage ont montré le potentiel de celle-ci comme science intégrative des connaissances écologi-ques générées à différents niveaux hié-rarchiques (Polis et al 1997) et en tant qu'outil de gestion de l'aménagement du territoire (Domon et Falardeau 1995). Elle peut ainsi servir de fondement pour le développement de nouvelles voies de recherche et d'intervention en phytoprotection.…”

“…: boisé) ou agricole (ex. : champ) est influencée parfois de manière très importante par les caractéristiques et l'organisation spatiale des éléments qui les environnent (Polis et al 1997), et que, par conséquent, le contrôle (au moins naturel) des ravageurs en est lui-même affecté. La recherche et les stratégies phytosanitaires doivent donc s'opérer à une échelle qui permette la prise en compte de telles influences.…”

Cet article de synthèse établit un lien entre la diversification des systèmes agricoles et le contrôle naturel des insectes ravageurs d'une part, et l'écologie du paysage d'autre part. L'analyse de la revue de littérature réalisée suggère que cette jeune science et le recours à la géomatique pourraient non seulement permettre de concevoir de nouvelles approches en recherche, mais aussi de participer à l'aménagement des agroécosystèmes à des fins de phytoprotection dans une perspective d'agriculture durable au Québec.In this review we establish a link between the diversification of agricultural systems and natural control of crop pests in one hand, and in the other hand the potential contribution of a young science, landscape ecology, which associated with geomatic, can elaborate new ways in research and take part in managing agroecosystems for crop protection in a sustainable manner in Québec

“…Otherwise, the nature and importance of linkages among various marine and even terrestrial ecosystems are poorly known. Coastal benthiddeinersal systems are especially interesting in this regard because they are juxtaposed with the land on one side and the open sea on the other, and in both cases significant linkages between systems occur via physical (oceanic, atmospheric, riverine) and biological (mobile species) transport mechanisms (Polis et al 1997, Paerl et al 1998. New opportunities for the study of such processes are available with recent developments in isotopic analyses, remote sensing, satellite imagery, CIS technology, and instrumentation for tracking animals at sea.…”

Research in seashore and seafloor communlt~es has contributed mmensely to the conceptual growth of ecology Here we summarize some of the most Important findings and discuss needs and opportunities for future work Dispropoi t~onately large numbers of the most influential contrlbutlons are derived from studies of rocky short 5 and coral reefs because aspects of these systems (accessibility) and of their most common species (sessile or weaklv motile, high density short generation tline) make them well suited to manipulative experiments Foremost among the research contributions froin seashore and seafloor systems are increased understanding of (1) competition and consumer-prey interactions, (2) trophic cascades and other Indirect specles ~nteractions (3) the evolution of defense and resistance in consumer-prey systems (4) the importance of propagule transport and recruitment v a n a t~o n to adult populations (5) the impacts of physlcal d~sturbance and (6) the generation and maintenance of specles diversity on ecological t~r n e scales We acknowledge the importance of manipulative expenments in the growth of marine ecology but question whether a stnct adherence to this approach will best serve future needs Some of the most pressing needs for future knowledge are (1) documenting the complex influences of spatial and temporal scales on ecological processes, (2) identifying the role of large, mobile predators in manne ecosystems, (3) understanding factors hmitlng manne autotrophs, (4) integrating historical biology and neontology and (5) appreciating intersystem linkages Increased attention to conducting arrays of expenments, taking measurements and observations, and documenting change at larger scales of space and time will provlde lnsights that are unattainable by the commonly used methodological protocols Novel approaches, including (1) evaluating and managing human disturbance for the loint purpose of conservation and learning, (2) developing stronger ties between scientists worhlng in open-ocean and near-shore systems and (3) developing collaborative prolects among scientists In the academic governmental, and pnvate sectors are required to understand many of these processes
