Spatial characteristics and temporal evolution of chemical and biological freshwater status as baseline assessment on the tropical island San Cristóbal (Galapagos, Ecuador) [PDF]

, 2019
The fragility of geographically isolated islands stresses the necessity of evaluating the current situation, identifying temporal trends and suggesting appropriate conservation measures. To support this, we assessed the freshwater quality of three stream

Les introductions de crustacés décapodes d'eau douce en France. Peut-on parler de gestion ?

Knowledge and Management of Aquatic Ecosystems, 1997
La proportion d'espèces allochtones dans les peuplements français de crustacés décapodes d'eau douce est importante. Pour deux espèces de crevettes (famille des Atyidae) et trois espèces d'écrevisses (famille des Astacidae) autochtones, on compte quatre ...
