Sensibilite Thermique d'un Copepode Harpacticoide: Tigriopus brevicornis Muller.
Provedor de dados: 5
Using a continuous breeding of T. brevicornis the authors try to approach an experimental procedure in order to estimated the effects of thermal stresses on larvae produced by ovigerous females. In spite of the main factor driving to successful breeding was the healthiness of algal food, sublethalt or inhibitory effects were observed with duration were only observed to LT 50 level. On opposite, decrease in nauplii production is noted just after ovigerous females are exposed to 35 degree C of final temperature.

Acetylcholinesterase activity in copepods (Tigriopus brevicornis) from the Vilaine River estuary, France, as a biomarker of neurotoxic contaminants
Provedor de dados: 5
Autores: Forget, Joelle; Beliaeff, Benoit; Bocquene, Gilles.
From April 1997 to June 1998, 14 measurements of acetylcholinesterase (AChE) enzymatic activity were performed with the copepod, Tigriopus brevicornis, collected at five stations in the Vilaine River estuary (South Brittany, France). Simultaneously, four chemical analyses of triazines and one analysis of total pesticides in water were undertaken. AChE activity levels in T brevicornis were compared to the levels measured at a reference site not exposed to effluents from Vilaine River. Results reveal significant differences between AChE activity levels depending on location of stations in the plume of the river with an increasing gradient of activity from the upstream to the downstream stations, thus indicating that neurotoxic contaminants are mainly brought...
