Abstract Hybridization between the European smooth and palmate newts has recurrently been mentioned in literature. The only two studies that attempted to quantify frequency of hybridization gene admixture these species came strikingly opposite conclusions. According Arntzen et al (1998, 42 allozymes), hybrids are rare nature introgression negligible, while according Johanet (2011, 6 microsatellites), introgressive is significant widespread across shared distribution range. To clarify this question, we implemented high-throughput SNP genotyping with diagnostic biallelic SNPs on 965 specimens sampled Europe. Our results line al, since F1 were identified distinct French localities, no further hybrid generations or backcrosses. Moreover, reanalysis 78 samples previously studied by al. (2011) using our panel could not reproduce their results, suggesting microsatellite-based inference overestimated species. Since did detect methodological issues analyses al., suggest approaches outperform assessments frequency, conclusions published topic a small number microsatellite loci should be taken caution, ideally repeated an increased genomic coverage.

The recent elevation of Lepomis peltastes (Northern Sunfish) as a separate species from L. megalotis (Longear has resulted in an incomplete understanding the species' distribution Illinois, most occurrence records cannot differentiate 2 species. We evaluated Northern Sunfish and Longear specimens to identify morphological characteristics that could species; relative body depth, opercular flap length, pectoral fin ray count were useful. reevaluated 867 Illinois Natural History Survey Fish Collection identified 103 Sunfish. Based on these specimens, it is probable occur 14 basins eastern half range extends farther south than was previously estimated.
