Is the Queen conch Strombus gigas (Mesogastropoda: Strombidae) a species with Allee effect?

The marine park of Xel-Há has a population of Strombus gigas which breeds in the area. We deter - mined the relationship between reproductive activity , conch density and environmental parameters. Samples were collected from February to December 2012, using the transect method, at four sites of Mari...
