Life History, Abundance, Activity, and Special Behaviors
In the Ambystoma genus, there are unisexual populations that can hybridize with A. jeffersonianum, A. laterale, A. texanum, A. trigrinum, and A. barbouri to create ploidy-elevated offspring. They can range from diploid to pentaploid and there are over 20 different nuclear genomic combinations. Most Ambystoma unisexuals have an A. laterale nuclear genome, while the other types of donated genomes can replace each other, as seen in recent populations of A. barbouri being the replacement donor for A. jeffersonianum. Ambystoma unisexuals’ mtDNA is most similar to A. barbouri, however A. barbouri is the least common sperm donor. Tetraploid and pentaploid unisexuals tend to have a higher mortality rate than triploid unisexuals (Bogart et al. 2009).
