“…In comparison with our findings, on average, native range Burmese pythons had nearly twice the number of alleles and higher average heterozygosities, with the exception of the Yunnan population, which had similar allelic values (N A = 5; Duan et al, 2017). In the invasive population, effective population sizes were relatively low, supporting the hypothesis that the population was established by a small number of founders and/or closely related individuals (Willson et al, 2011).…”

“…Limited introgression of P. molurus followed by backcrossing to P. bivittatus may have occurred in the large, widely distributed commercial trade populations. Alternatively, intraspecific genetic divergence in the P. bivittatus native range may have contributed to the three nuclear groups found in China ( F ST = 0.11 overall), although assessment of mitochondrial DNA is needed to determine whether divergent mitotypes are also present (Duan et al., ).…”

“…Invasive Florida population‐specific microsatellite markers for P. bivittatus were subsequently isolated ( N = 18) and combined with six cross‐species markers to identify 61% average expected heterozygosity ( H E ) and 2–6 alleles per locus ( N A ; 3.7 average N A ; Hunter & Hart, ). In comparison, higher levels of genetic diversity ( N A = 10.88) were identified for P. bivittatus in the native range using eight microsatellites (Duan et al., ).…”

The invasive Burmese python (Python bivittatus) has been reproducing in the Florida Everglades since the 1980s. These giant constrictor snakes have caused a precipitous decline in small mammal populations in southern Florida following escapes or releases from the commercial pet trade. To better understand the invasion pathway and genetic composition of the population, two mitochondrial (mtDNA) loci across 1,398 base pairs were sequenced on 426 snakes and 22 microsatellites were assessed on 389 snakes. Concatenated mtDNA sequences produced six haplotypes with an average nucleotide and haplotype diversity of π = 0.002 and h = 0.097, respectively. Samples collected in Florida from morphologically identified P. bivittatus snakes were similar to published cytochrome oxidase 1 and cytochrome b sequences from both P. bivittatus and Python molurus and were highly divergent (genetic distances of 5.4% and 4.3%, respectively). The average number of microsatellite alleles and expected heterozygosity were N A = 5.50 and H E = 0.60, respectively. Nuclear Bayesian assignment tests supported two genetically distinct groups and an admixed group, not geographically differentiated. The effective population size (N E = 315.1) was lower than expected for a population this large, but reflected the low genetic diversity overall. The patterns of genetic diversity between mtDNA and microsatellites were disparate, indicating nuclear introgression of separate mtDNA lineages corresponding to cytonuclear discordance. The introgression likely occurred prior to the invasion, but genetic information on the native range and commercial trade is needed for verification. Our finding that the Florida python population is comprised of distinct lineages suggests greater standing variation for adaptation and the potential for broader areas of suitable habitat in the invaded range.

“…Fifteen out of 17 primers produced various number of alleles which ranged from 1 to 3 for P. bivittatus, 1 to 2 for P. brongersmai, and 2 to 8 for P. breitensteini. However, we found fewer alleles than those observed for MS9 and MS16 loci [9]; and for MS5, MS13, and MS16 loci [10]. Nevertheless, this discrepancy might due to differences in sample sizes between the three studies.…”

“…The use of microsatellite markers has been widely developed to detect illegal trade in many species such as broad-headed snakes, Hoplocephalus bungaroides [5], Cape parrot, Poicephalus robustus [6], and the identification of ivory species origin traded in African black market [7]. Previous studies also revealed the use of microsatellite primers on python, such as those for Australian and New Guinean pythons [8], invasive Burmese python (Python molurus bivittatus) [9] and Python bivittatus in China [10]. Meanwhile, little is known about Indonesian Sundaland pythons, including their genetic diversity.…”

The python of Indonesian Sundaland has been traded for its distinct skin colour and patterns. The need for rapid method in cross-species amplification for Indonesian Sundaland python is useful to contribute in management of sustainability harvesting system. In this research, we screened 10 microsatellite primers which are previously used for Australian, New Guinean, Chinese and Burmese pythons and 7 potentially amplifiable primers for African and Asian reptiles. Python breitensteini showed a greater number of alleles (2-8 alleles) than Python bivittatus (1-3 alleles) and Python brongersmai (1-2 alleles). The observed and expected heterozygosity for all species were ranged from 0 to 1.00 and 0 to 0.79, respectively. According to the high cross-species amplification rates, 15 out of 17 primers were useful in assessing the genetic diversity and conservation genetic of Indonesian Sundaland python. Among the 15 primers, MS3 generated the highest number of allele for P. breitensteini (8 alleles), P. bivittatus (3 alleles), and P. brongersmai (2 alleles). We proposed MS3 locus as a suitable marker for Indonesian Sundaland python.

Information on demographic, genetic, and environmental parameters of wild and captive animal populations has proven to be crucial to conservation programs and strategies. Genetic approaches in conservation programs of Brazilian snakes remain scarce despite their importance for critically endangered species, such as Bothrops insularis, the golden lancehead, which is endemic to Ilha da Queimada Grande, coast of São Paulo State, Brazil. This study aims to (a) characterize the genetic diversity of
