Abstract The widespread Mexican apple snail Pomacea flagellata (Say 1827) and the strictly endemic
"tegogolo" P. patula catemacensis (Baker 1922) (restricted to Lake Catemaco), are the only known American
Ampullariidae that have haploid complements n=13. Pomacea patula catemacensis has suffered a critical
reduction in abundance due to immoderate fishing for human consumption. Chromosome slides were obtained from colchicine-injected Pomacea snails collected from nine locations along the coastal zone of the
Gulf of Mexico, including Lake Catemaco, for use in principal component analysis (PCA). Total proteins in
foot homogenates were analyzed through isoelectric focusing (IEF) and native-PAGE electrophoresis on polyacrylamide gels. The… More >
