| A priorização das ações de pesquisa é imprescindível pela necessidade de alcançar, com recursos limitados, os objetivos e as metas das instituições e do país. Isto, geralmente, ocorre num ambiente de intensa competição entre organizações e países, aliada à preocupação da sociedade com a conservação ambiental e com as questões sociais. Este cenário é, também,caracterizado pelo grande número de demandas endereçadas às organizações de pesquisa, as quais, nem sempre têm condições de produzir ou viabilizar as soluções. É necessário, ainda, considerar a existência de novas fronteiras do conhecimento, fato que amplia o número de alternativas tecnológicas para a solução de problemas. A priorização de pesquisa naárea florestal é ainda mais necessária que na... |

| (Not controled OCR) The different statistical data sources available for seafood I consumption analysis in France belong to three types : the apparent consumption estimated on the basis of a balance between production and trade, used at national scale and for international comparison, the data in value published by the national Institute for economic statistics, aggregating food balance sheet, and economic results of inquiries about the activities of the branch industries, and the household consumption estimated through consumers' panels. A critical and historical analysis of the different available data series is presented, with focus on the major difficulties when interpreting and cross-checking the data (series breaking-nomenclature items, range of... |

| The Abra alba community from the Gravelines area has been studied since 1976. During this period, sudden and unpredictable variations of the species composition have been observed. These important changes affect a limited number of species without changing the bionomical structure of the community. The species in question are found to be characteristic of this community, and are the more abundant ones. Multivariate statistical methods were used to study quantitative data on the benthic population collected from 1978 to 1992. This analysis was performed in association with air temperature data. Results showed the existence of a six- or seven-year cycle, and this is confirmed by the observation of two complete periods. This cycle, which is found to be... |

| Determining the lipid content and fatty acid (FA) composition of aquatic organisms has been of major interest in trophic ecology, aquaculture, and nutrition for over half a century. Although protocols for lipid analysis are well-described, their application to aquatic sciences often requires modifications to adapt to field conditions and to sample type. Here, we present the current state of knowledge of methods dedicated to both marine and freshwater lipid analyses, from sampling to data treatment. We review: (i) sample preservation, storage and transport protocols, and their effects on lipids, (ii) lipid extraction, separation of polar and neutral lipids, derivatization, and detection methods, and (iii) available tools for the statistical analysis of FA... |

| Numerous studies have compared the rates of primary production using various techniques at specific locations and times. However, these comparisons are local and cannot be used to compare or scale rates of primary production using different methods across ocean basins or seasonal time scales. Here, we quantify the range in rates of primary production derived using different techniques and provide equations that allow conversions of estimates between different methods. We do so on the basis of a compilation of data on volumetric estimates of primary production rates concurrently estimated with at least two different methods. We observed that the comparison of estimates of marine phytoplankton primary production derived from different methods reveals very... |

| Single-cell genetic analysis is an essential method to investigate the biodiversity and evolutionary ecology of marine protists. In protist groups that do not reproduce under laboratory conditions, this approach provides the only means to directly associate molecular sequences with cell morphology. The resulting unambiguous taxonomic identification of the DNA sequences is a prerequisite for barcoding and analyses of environmental metagenomic data. Extensive single-cell genetic studies have been carried out on planktonic foraminifera over the past 20 years to elucidate their phylogeny, cryptic diversity, biogeography, and the relationship between genetic and morphological variability. In the course of these investigations, it has become evident that genetic... |

| We compared the ability of three direct methods (increment summation, loss summation and instantaneous growth rate coefficient), the size-frequency method, and eight indirect methods (Banse and Mosher, Benke, Brey, Edgar, Morin and Bourassa, Plante and Downing, Robertson and Schwinghamer et al.) to measure or to predict the secondary production of a Mediterranean population of the polychaete Ditrupa arietina. This comparison was carried out both on the 1994 cohort during its two-year lifespan and on the entire population during the two years of the study (1994-1996). Our results showed that all three direct methods are more or less equivalent. Results referring to the year 1994-1995 showed a strong overestimation of the actual production by the size... |

| Flume tanks are becoming increasingly important research tools in aquatic ecology, to link biological to hydrodynamical processes. There is no such thing as a "standard flume tank", and no flume tank is suitable for every type of research question. A series of experiments has been carried out to characterise and compare the hydrodynamic characteristics of 12 different flume tanks that are designed specifically for biological research. These facilities are part of the EU network BioFlow. The flumes could be divided into four basic design types: straight, racetrack, annular and field flumes. In each facility, two vertical velocity profiles were measured: one at 0.05 m s(-1) and one at 0.25 m s(-1). In those flumes equipped with Acoustic Doppler Velocimeters... |

| We evaluated the application of faecal analysis as a complementary approach to direct observation in the study of Callithrix jacchus feeding ecology. Our results indicate that animal foods may be more commonly consumed (based on faecal samples-FS; 61.48% of diet) than previously thought (e.g., only 22.83% based on observational data-OD). Whereas FS provide better data on animal prey, it was less effective than OD in identifying plant items. Six insect orders-including Dermaptera and two hymenopteran families, not previously recorded in marmoset diet-were identified through FS, which is thus shown to be useful in characterizing diet, especially in insectivorous primates. |
