An integrative taxonomic analysis of the Cyrtodactylus linnwayensis group of the Shan Plateau recovered two new populations from isolated karst habitats near Pinlaung Town, Shan State as a new species, C. pinlaungensis sp. nov. Cyrtodactylus pinlaungensis sp. nov. is most closely related to a clade comprising C. linnwayensis and C. ywanganensis from the western edge of the Shan Plateau approximately 90 km to the northwest. Cyrtodactylus pinlaungensis sp. nov. can be distinguished from all members of the C. linnwayensis group by a number of statistically different morphological characters, discrete color pattern differences, and its heavy tuberculation. It also bears an uncorrected pairwise sequence divergence of 5.0–7.6% from all other species combined based on the mitochondrial gene ND2 and its flanking tRNAs. The discovery of this new species on the Shan Plateau continues to underscore the fact that this region is rapidly emerging as a herpetological diversity hot-spot for Myanmar.

During survey on rock-inhabiting fungi from karst habitats in Guizhou, China, two new species in Cyphellophora were discovered and identified. Phylogenetic analysis based on combined sequences of the nuclear large subunit (nucLSU) and internal transcribed spacer (ITS) region of ribosomal DNA revealed that the tested isolates, clustered into two clades that well affiliated in the genus of Cyphellophora. Morphological characteristics were also supported the estabolishment of the new species. Herewith Cyphellophora botryose sp. nov. and Cyphellophora guizhouensis sp. nov. were described and their differences from closely related species were discussed.

We describe three new gecko species of the Paroedura oviceps clade, diagnosed by deep divergences in mitochondrial DNA, absence of haplotype sharing in two nuclear genes (sacs and kiaa1239), and morphological differences. Paroedura spelaea sp. nov. is an extremely slender species from karst habitats in the limestone massif of the Tsingy de Bemaraha National Park in western Madagascar, morphologically reminiscent of P. homalorhina but distinguished by the absence of distinct dorsal rows of spiny tubercles. Paroedura fasciata sp. nov. from the small karstic island Nosy Hara in northern Madagascar is phylogenetically placed sister to P. spelaea despite radical morphological differences. It is morphologically most similar to P. hordiesi from the geographically close Montagne des Français massif, but is smaller, has slightly more spiny dorsal scales, and a distinctive colour pattern with light grey dorsal crossbands. The third species, Paroedura kloki sp. nov., is known from Ankarafantsika National Park and the western slopes of Makira, two sites of dry to transitional forest in western Madagascar. It is at least partly arboreal and morphologically very similar to P. oviceps, from which it differs by spiny scales extending over its entire tail. Although incomplete, the available phylogenetic evidence suggests that the karst specialists in the P. oviceps clade (P. fasciata, P. homalorhina, P. hordiesi, P. spelaea) form a monophyletic group which might have diversified by vicariance after becoming isolated, respectively, in their limestone habitats in Tsingy de Bemaraha, Ankarana, Nosy Hara and Montagne des Français.

Abstract. In view of future coastal hypoxia widespreading, it is essential to define management solutions to preserve a good quality of coastal ecosystems. The lower Tidal Garonne River (TGR, SW France), characterized by the seasonal presence of a turbidity maximum zone and urban water discharges, is subject to episodic hypoxia events during summer low river flow periods. The future climatic conditions (higher temperature; summer droughts) but also an increasing urbanization could enhance hypoxia risks near the city of Bordeaux in the next decades. A 3D model of dissolved oxygen (DO), which couples hydrodynamics, sediment transport and biogeochemical processes, is used to assess the efficiency of different management solutions on TGR oxygenation during summer low-discharge periods. We have runned different scenarios of reduction of urban sewage overflows, displacement of urban discharges downstream from Bordeaux, and/or temporary river flow support during summer period. The model shows that each option limits hypoxia, but with variable efficiency over time and space. Sewage overflow reduction improves DO levels only locally near the city of Bordeaux. Downstream relocation of wastewater discharges allows to reach better oxygenation level in the lower TGR. The support of low river flow limits the upstream TMZ propagation and dilutes TGR waters with well-oxygenated river waters. Scenarios combining wastewater network management and low water replenishment indicate an improvement in water quality over the entire TGR. These modelling outcomes constitute important tools for local water authorities to develop the most appropriate strategies to limit hypoxia in TGR.
