| biological indices, energy reserves, steroid hormones and sexual maturity in the infaunal bivalve scrobicularia plana from three sites differing by their level of contamination. | the aim of this work was to investigate in situ biometric (condition index, hepato-somatic index, gonado-somatic index), biochemical (glycogen, lipids, sexual steroids) and histological (sex, sexual maturation stage) variables in the infaunal bivalve scrobicularia plana. first, the reproductive cycle of s. plana was assessed by collecting bivalves from a reference site (the bay of bourgneuf, fr) in april, may, july, september and november 2005 and in january and march 2006. then, s. plana were c ... | 2008 | 18511050 |
| vg mrna induction in an endangered fish species (anguilla anguilla) from the loire estuary (france). | estuarine zones are extremely fragile due to increasing stress from anthropogenic activities. among those, the loire estuary (france) is potentially exposed to various contaminants including endocrine disruptors compounds (edcs) able to impact the reproduction physiology of fish. the european eel (anguilla anguilla), endangered fish species, is apparently not relevant, in its yellow stage, to monitor the effects of endocrine disruption. despite this weakly responsiveness, this study aimed to inv ... | 2013 | 23993220 |
