An integrative taxonomic analysis based on morphology, color pattern, and the mitochondrial gene ND2 recovered four new species of Hemiphyllodactylus Bleeker that are endemic to the Shan Plateau or Salween Basin in eastern Myanmar. Hemiphyllodactylus ngwelwini sp. nov. from the Shan Plateau is part of the earlier described “eastern Myanmar clade” renamed herein as the north lineage and H. kyaiktiyoensis sp. nov. and H. pinlaungensis sp. nov. of the Shan Plateau and H. zwegabinensis sp. nov. of the Salween Basin compose an entirely new Burmese clade herein referred to as the south lineage. Although the north and south lineages come within 46 km of one another on the Shan Plateau, they are not sister lineages but sequentially separated by two lineages from Yunnan, China and another from northwestern Thailand. Hemiphyllodactylus zwegabinensis sp. nov. is the first species of this genus to be recorded from the Salween Basin and is known only from a wind-blown cloud forest on the top of the insular, karstic mountain Zwegabin in Kayin State. All other Burmese species except for H. typus, are endemic to the various localities throughout the Shan Plateau. These four new species bring the total number of Hemiphyllodactylus in Myanmar to at least 10 which is certainly an extreme underestimate of the diversity of this genus given that we discover new species at every upland locality we survey.

Species of Garra (Cyprinidae: Labeoninae) in the Salween River basin with description of an enigmatic new species from the Ataran River drainage of Thailand and Myanmar
Garra panitvongi, new species, is described from the Ataran River drainage, Salween River basin, of southeastern Myanmar and western Thailand. It is the sixth species of Garra known from the Salween River basin and is readily distinguished from all congeners by the red-orange color of the body and caudal fin, and a pointed proboscis with a blue stripe on each side from the anterior margin of the orbit to the tip of the proboscis and with the stripes forming a V-shape. Garra panitvongi is known in the aquarium trade as the Redtail Garra. Descriptive information is provided on poorly known species of Garra in the Salween River basin, and Garra nujiangensis is transferred to Ageneiogarra.

Co-management is increasingly recognized as an effective model for managing fisheries, but little information exists on whether co-management can produce effects in species other than the target species. Fishery co-management in the tropics, where fish diversity is high and fish catches tend to be multispecies, is prone to produce assemblage-wide effects via alterations in the food web and changes in the overall capture of non-target species. Here, we assessed the effects of co-management for the species Arapaima sp. in relation to the structure and composition of the overall fish assemblage in floodplain lakes of the central Amazon Basin. These floodplain lakes are managed under a system of zoning of fishing activities. We used data from surveys of six floodplain lakes, including two lakes of each of three categories (lakes where fishing is prohibited, limited-access lakes, and open fishing lakes). The surveys were carried out before and after implementation of co-management, through gillnet fishing. The study area was the lower Solimões River, in the Amazon Basin, Brazil. Statistical models showed significant changes in the composition and structure of the fish assemblages after the implementation of the co-management, regardless of the zoning category. Through regulation of gear use and fishing practices, co-management allowed the colonization of species that had not been present before, which lead to higher richness and consequently increased fish sizes, abundance and biomass. Species of sedentary habits, migrants of short and medium distances, with commercial importance benefited the most from co-management. In the results presented in temporal scale, it was possible to observe a potential spillover effect being provided by the lakes where fishing is prohibited (no-take zones) and those of limited access that benefited those open to fishing. Thus, co-management had positive effects in the structure and composition of fish assemblages in all lakes, regardless of zoning category.more » « less

An integrative taxonomic analysis of the 10 species of the Cyrtodactylus sinyineensis group based on squamation, color pattern, and the mitochondrial gene NADH dehydrogenase subunit 2 (ND2) and its flanking tRNA regions, recovered the newly discovered populations from Datt Kyaik and Taung Wine Hills in Kayin State as the new species Cyrtodactylus dattkyaikensis sp. nov. and C. taungwineensis sp. nov. The Maximum Likelihood and Bayesian phylogenetic estimates supported C. dattkyaikensis sp. nov. as the sister species of C. bayinnyiensis and C. taungwineensis sp. nov. as the sister species of C. sinyineensis. Each new species is differentially diagnosable from all other C. sinyineensis group species based on their morphological placement in multivariate space and several statistically significant mean differences is meristic squamation and color pattern data. The C. sinyineensis group ranges across an archipelago of karstic habitat-islands in the Salween Basin of southern Myanmar. The discovery of these new species continues to underscore the unprecedented high degree of diversity and site-specific endemism in this relatively small region and the urgent need for the conservation of its karstic terranes.more » « less

Abstract As genomic-scale data sets become economically feasible for most organisms, a key question for conservation biology is whether the increased resolution offered by new genomic approaches justifies repeating earlier studies based on traditional markers, rather than investing those same time and monetary resources in less-known species. Genomic studies offer clear advantages when the objective is to identify adaptive loci that may be critical to conservation policy-makers. However, the answer is far less certain for the population and landscape studies based on neutral loci that dominate the conservation genetics research agenda. We used Restriction-site Associated DNA sequencing (RADseq) to revisit earlier molecular studies of the IUCN Critically Endangered Magdalena River turtle (Podocnemis lewyana), documenting the conservation insights gained by increasing the number of neutral markers by several orders of magnitude. Earlier research indicated that P. lewyana has the lowest genetic diversity known for any chelonian, and little or no population differentiation among independent rivers. In contrast, the RADseq data revealed discrete population structure with isolation-by-distance within river segments and identified precise population breaks clearly delineating management units. It also confirmed that the species does not have extremely low heterozygosity and that effective population sizes are probably sufficient to maintain long-term evolutionary potential. Contrary to earlier inferences from more limited population genetic markers, our genomic data suggest that management strategies should shift from active genetic rescue to more passive protection without extreme interventions. We conclude with a list of examples of conservation studies in other vertebrates indicating that for many systems a genomic update is worth the investment.

Abstract Characterizing genetically distinct populations of primates is important for protecting biodiversity and effectively allocating conservation resources. Skywalker gibbons (
Hoolock tianxing ) were first described in 2017, with the only confirmed population consisting of 150 individuals in Mt. Gaoligong, Yunnan Province, China. Based on river geography, the distribution of the skywalker gibbon has been hypothesized to extend into Myanmar between the N’Mai Kha and Ayeyarwaddy Rivers to the west, and the Salween River (named the Thanlwin River in Myanmar and Nujiang River in China) to the east. We conducted acoustic point-count sampling surveys, collected noninvasive samples for molecular mitochondrial cytochromeb gene identification, and took photographs for morphological identification at six sites in Kachin State and three sites in Shan State to determine the presence of skywalker gibbons in predicted suitable forest areas in Myanmar. We also conducted 50 semistructured interviews with members of communities surrounding gibbon range forests to understand potential threats. In Kachin State, we audio-recorded 23 gibbon groups with group densities ranging between 0.57 and 3.6 group/km2. In Shan State, we audio-recorded 21 gibbon groups with group densities ranging between 0.134 and 1.0 group/km2. Based on genetic data obtained from skin and saliva samples, the gibbons were identified as skywalker gibbons (99.54–100% identity). Although these findings increase the species’ known population size and confirmed distribution, skywalker gibbons in Myanmar are threatened by local habitat loss, degradation, and fragmentation. Most of the skywalker gibbon population in Myanmar exists outside protected areas. Therefore, the IUCN Red List status of the skywalker gibbon should remain as Endangered.
