Parentage test in broad-snouted caimans (Caiman latirostris, Crocodylidae) using microsatellite DNA Genet. Mol. Biol.
Zucoloto,Rodrigo B.; Verdade,Luciano M.; Villela,Priscilla M.S.; Regitano,Luciana C.A.; Coutinho,Luiz L..
In this study, microsatellite markers, developed for Alligator mississipiensis and Caiman latirostris, were used to assess parentage among individuals from the captive colony of Caiman latirostris at the University of São Paulo, in Piracicaba, São Paulo, Brazil. Many of the females in the colony were full siblings, which made maternal identification difficult due to genotypic similarity. Even so, the most likely mother could be identified unambiguously among offspring in most of the clutches studied. Two non-parental females displayed maternal behavior which would have misled managers in assigning maternity based on behavior alone. This set of variable loci demonstrates the utility of parentage testing in captive propagation programs.

Bases génétiques des caractères physiologiques impliqués dans la croissance chez l'huître creuse Crassostrea gigas (Thunberg) ArchiMer
Collet, Bertrand.
Growth is a very important trait in the oyster Crassoslrea gigas both from an economical and scientific point of view. Many questions remain unanswerable or are still discussed . From a hatchery-based population, the constancy in time of growth performances From larval to adult stage was studied. The influence of physiological parameters (energy acquisit ion and expenditure) and parentage on growth was estimated. ln the literature, the relationship between larval growth and post-Iarval growth is debated . Our study shows that the larval growth is positively correlated with the post-Iarval growth. This result validates the hatchery practices consisting in culling the small larvae. The growth performances are stable over the time and show no compensation....
