A large set of size data for yellowfin and bigeye tunas has been collected aboard Seychelles industrial longliners since 2007 and carefully checked and managed by the Seychelles Fishing Authority. Analysis of the data at the scale of the fishing operation shows that size frequency data collected at sea by fishermen are consistent with logbook infor...
We studied the tree-regeneration patterns in three distinct agricultural settlements in the Eastern Amazon to test the influence of land-use mosaics. The following questions are addressed: are the floristic structure and composition of regenerating trees affected by the various land-use types applied in the agricultural settlements? Do tree-regener...

On dénombre 128 espèces de poissons dans l'ensemble du bassin tchadien, mais aucune endémique. Le nombre d'espèces présentes dans le lac est un peu plus grand en situation de Moyen Tchad qu'en période de Petit Tchad, durant laquelle les espèces migratrices sont plus faiblement représentées. Les autres espèces n'ont pas pour autant disparu car elles...

La quinua (Chenopodium quinoa Willd.) muestra una gran variación genética, tanto molecular como morfológica, cuya organización sigue poco conocida. Por medio de ANOVAs y dendrograma caracterizamos la estructura de la variación de marcadores morfofenológicos registrados desde la emergencia hasta la madurez fisiológica en siete poblaciones de quinuas...
