Data from: Genetic evidence for polygamy as a mating strategy in Caiman crocodilus

Deyla Oliveira, Boris Marioni, Izeni Farias & Tomas Hrbek
The mating system of the spectacled caiman (Caiman crocodilus) was investigated in the Piaga├žu-Purus Sustainable Development Reserve, Amazonas, Brazil. We used six polymorphic microsatellite loci to genotype 15 females and 174 hatchlings representing 20 nests sampled over four consecutive reproductive seasons (2007 to 2010). Paternity was determined by two methods: simple counts, and statistical analysis using Gerud 2.0. Results were congruent between the two approaches, and the null hypothesis of single paternity was rejected in...

Data from: Known knowns, known unknowns, unknown unknowns and unknown knowns in DNA barcoding: a comment on Dowton et al.

Rupert A. Collins & Robert H. Cruickshank
In a recent commentary, Dowton et al. (2014) propose a framework for "next-generation" DNA barcoding, whereby multi-locus datasets are coupled with coalescent-based species delimitation methods to make specimen identifications. They claim single-locus DNA barcoding is outdated, and a multilocus approach superior, with their assertions supported by an analysis of 33 species of Sarcophaga flesh flies. Here, we reanalyse their data and show that a standard DNA barcode analysis is in fact capable of identifying 99.8%...
