The yacare caiman (Caiman yacare) is a reptile from South America and 1 of
the 2 crocodilian species present in Argentina. The degradation of their
natural habitat and strong hunting pressure led to a sharp numerical
decline of wild populations. Nowadays, C. yacare is included in Appendix
II of CITES, and ranching practices in some areas in Argentina are helping
hatching success. In this context, it is important to better understand
the population structure and mating system of the species. To do this, we
amplified 10 microsatellite markers (SSRs) in 148 individuals of 13 C.
yacare nests. All of the markers were polymorphic with 2–12 alleles per
locus, with allelic sizes ranging between 154 and 400 bp and medium levels
of polymorphism (H o = 0.152–0.551 and H e = 0.221–0.621). We were able to
determine the maternal genotype in 9 out of 13 nests. In 6 of them we
found more than 1 paternal genotype, with a maximum of 3 fathers for a
single nest. This study is the first to provide evidence of multiple
paternity behavior. These findings will be useful to improve management
and conservation strategies for the species.
