The objective of this study was to examine population structure in
cottonmouths (Agkistrodon piscivorus ) using Amplified Fragment Length
Polymorphism (AFLP ) and compare genetic and venom protein profiles in Texas .
AFLP profiles using 622 fragments were generated for 105 individuals to understand
the level of variation within Agkistrodon . In Texas , there was a significant lack of
gene flow detected and support for the isolation of Concho Valley individuals .
Cottonmouths showed the greatest genetic variation when compared to other
Agkistrodon species but there was not complete support for two species of
cottonmouths as currently proposed . RP -HPLC was used to examine venom protein
profiles in 86 Texas cottonmouths . Relative peak heights were analyzed using PCA
and the MANOVA demonstrated separation of populations based on profiles
(p <0 .001 ) . Genetic and venom variation did not follow the same pattern indicating
that there may be other selection pressures acting on the venom proteins . |
