Comparative analysis of trophic structure and interactions of two tropical lagoons
Provedor de dados: 5
Autores: Villanueva, Ching-maria; Laleye, P; Albaret, J; Lae, Raymond; Tito De Morais, Luis; Moreau, J.
A comparative study of the Ebrie lagoon (Ivory Coast) and Lake Nokoue (Benin) was made based on ecotrophic model outputs that describe each system's structure and functioning. Two models were constructed using the Ecopath software to differentiate main biomass flows in the systems.   Results indicate that biomasses and productions in both ecosystems are concentrated in trophic levels (TL) 2 and 3. Higher TL biomasses and productions in Lake Nokoue compared to Ebrie lagoon may be explained by the presence of acadjas. High production per biomass (P/B) and food consumption per biomass (Q/B) values indicate the high productivity of these systems and the abundance of juveniles in most groups which utilize these systems as refuge zones and nurseries. The...

Fish Species in a Changing World: The Route and Timing of Species Migration between Tropical and Temperate Ecosystems in Eastern Atlantic
Provedor de dados: 5
Autores: Kaimuddin, Awaluddin H.; Laë, Raymond; Tito De Morais, Luis.
The presence of tropical species has been reported in Atlantic-European waters with increasing frequency in recent years. Unfortunately, the history of their migrations is not well understood. In this study, we examined the routes and timing of fish migrations in several ecosystems of the East Atlantic Ocean, combining several publicly available and unpublicized datasets on species occurrences. The species studied were those noted as exotic or rare outside their previous known area of distribution. We used sea surface temperature (SST) data obtained from 30 years of satellite observation to define three distinct time periods. Within these periods, temperature trends were studied in six ecosystems: the North Sea, the Celtic Sea, the South European Atlantic...

Metal subcellular partitioning determines excretion pathways and sensitivity to cadmium toxicity in two marine fish species.
Provedor de dados: 5
Autores: Le Croizier, Gael; Lacroix, Camille; Artigaud, Sebastien; Le Floch, Stephane; Munaron, Jean-marie; Raffray, Jean; Penicaud, Virginie; Rouget, Marie-laure; Lae, Raymond; Tito De Morais, Luis.
Subcellular cadmium (Cd) partitioning was investigated in the liver of two marine fish species, the European sea bass Dicentrarchus labrax and the Senegalese sole Solea senegalensis, dietary exposed to an environmentally realistic Cd dose for two months followed by a two-month depuration. Cd exposure did not modify Cd cellular partitioning for either species, refuting the spillover hypothesis. Both species contained most of the Cd in the detoxifying fraction but displayed different handling strategies. Cd was largely bound to heat stable proteins (HSP) including metallothioneins (MT) in sea bass while Cd was more linked to metal rich granules (MRG) in sole. Whole liver concentrations and subcellular partitioning were also determined for essential elements....

The PPEAO experimental fishing dataset: Fish from West African estuaries, lagoons and reservoirs
Provedor de dados: 5
Autores: Simier, Monique; Ecoutin, Jean-marc; Tito De Morais, Luis.
Background This paper describes a dataset of fish, crustacean and mollusc occurrences extracted from the “Experimental Fishing” section of the IRD's PPEAO information system. PPEAO stands for “Fish communities and artisanal fisheries of West African estuarine, lagoon and freshwater ecosystems”. This database contains information collected using two different methods: experimental fishing and surveys of the artisanal fisheries that exploit these ecosystems. The database is accessible at http://ppeao.ird.fr. New information The current dataset is available on GBIF.org at 10.15468/ra4voa. It comprises the occurrences of 314 fish, crustacean and mollusc taxa collected in experimental sampling surveys of different aquatic ecosystems in West Africa between 1979...
