When we were given the opportunity to conduct The baseline study for Thane creek” we felt blessed to learn more about this unique ecosystem the largest creek from asia. This study was possible due to Mr. N Vasudevan, IFS, CCF, Mangrove cell, Maharashtra whose vision for the mangrove habitats in Maharashtra has furthered the cause of conservation. Hence, we thank him for giving us this opportunity to be a part of his larger goal. The present study involved interactions with a number of research institutions, educational institutions, NGO’s and community, all of whom were cooperative in sharing information and helped us. Most important was the cooperation of librarians from all the institutions who went out of their way in our literature survey. -

We aimed: (i) to investigate the distribution patterns of Odonata in streams on a nationwide scale across South Korea; (ii) to evaluate the relationships between the distribution patterns of odonates and their environmental conditions; and (iii) to identify indicator species and the most significant environmental factors affecting their distributions. Samples were collected from 965 sampling sites in streams across South Korea. We also measured 34 environmental variables grouped into six categories: geography, meteorology, land use, substrate composition, hydrology, and physicochemistry. -

Smith (1945) made a partial attempt to straighten .the tangle, but writers seem still to adhere to earlier systems of classification, partly on account of Smith's work not being accessible as ready reference. Since 1945 some more literature has come out on the taxonomy of these fishes, and the present revision is therefore undertaken in order to help to avoid continuance of improper usage and to give an up-to-date classification of the fishes belonging to Hamilton's division Chela, which is now recognised as a distinct genus of the subfamily Abramidinae of the family Cyprinidae. HISTORICAL REsUME Under the division Chela of the genns Cyprinus, Hamilton described a heterogenons assemblage of seven species.

The Superfamily Calopterygoidea in South China: Taxonomy and Distribution. Progress Report for 2009 Surveys Zhang Haomiao* *PH D
International Dragonfly Fund - Report 26 (2010): 1-36 1 The Superfamily Calopterygoidea in South China: taxonomy and distribution. Progress Report for 2009 surveys Zhang Haomiao* *PH D student at the Department of Entomology, College of Natural Resources and Environment, South China Agricultural University, Guangzhou 510642, China. Email: [email protected] Introduction Three families in the superfamily Calopterygoidea occur in China, viz. the Calo- pterygidae, Chlorocyphidae and Euphaeidae. They include numerous species that are distributed widely across South China, mainly in streams and upland running waters at moderate altitudes. To date, our knowledge of Chinese spe- cies has remained inadequate: the taxonomy of some genera is unresolved and no attempt has been made to map the distribution of the various species and genera. This project is therefore aimed at providing taxonomic (including on larval morphology), biological, and distributional information on the super- family in South China. In 2009, two series of surveys were conducted to Southwest China-Guizhou and Yunnan Provinces. The two provinces are characterized by karst limestone arranged in steep hills and intermontane basins. The climate is warm and the weather is frequently cloudy and rainy all year. This area is usually regarded as one of biodiversity “hotspot” in China (Xu & Wilkes, 2004). Many interesting species are recorded, the checklist and photos of these sur- veys are reported here. And the progress of the research on the superfamily Calopterygoidea is appended. Methods Odonata were recorded by the specimens collected and identified from pho- tographs. The working team includes only four people, the surveys to South- west China were completed by the author and the photographer, Mr. -

These photographs revealed that only Euphaeaamphicyana reflected UV from its other wings whereas all spp. either did not absorb UV (e.g. 94.5% of the Coenagri- did In with flavescent. onidae) or so to varying degrees. particular, spp. orange or brown UV these wings (or wing patches) exhibited absorption for same areas. However, other spp. with nearly transparent wings (especially certain Gomphidae) Pruinose also had strong UV absorption. body regions reflected UV but the standard acetone treatment for color preservation dissolves thewax particles of the pruinosity and destroys UV reflectivity. As is typical for arthropod cuticle, non-pruinosebody regions absorbed UV and this obscured whatever color patterns might otherwise be visible without the camera’s UV filter. Frequently there is sexual dimorphismin UV and and these role various of patterns (wings body) differences may play a in aspects mating behavior. INTRODUCTION Considerable attention has been paid to the various ultraviolet (UV) patterns exhibited by the Lepidoptera (e.g. SCOTT, 1973).

Resolving Cypriniformes Relationships Using an Anchored Enrichment Approach Carla C
Stout et al. BMC Evolutionary Biology (2016) 16:244 DOI 10.1186/s12862-016-0819-5 RESEARCH ARTICLE Open Access Resolving Cypriniformes relationships using an anchored enrichment approach Carla C. Stout1*†, Milton Tan1†, Alan R. Lemmon2, Emily Moriarty Lemmon3 and Jonathan W. Armbruster1 Abstract Background: Cypriniformes (minnows, carps, loaches, and suckers) is the largest group of freshwater fishes in the world (~4300 described species). Despite much attention, previous attempts to elucidate relationships using molecular and morphological characters have been incongruent. In this study we present the first phylogenomic analysis using anchored hybrid enrichment for 172 taxa to represent the order (plus three out-group taxa), which is the largest dataset for the order to date (219 loci, 315,288 bp, average locus length of 1011 bp). Results: Concatenation analysis establishes a robust tree with 97 % of nodes at 100 % bootstrap support. Species tree analysis was highly congruent with the concatenation analysis with only two major differences: monophyly of Cobitoidei and placement of Danionidae. Conclusions: Most major clades obtained in prior molecular studies were validated as monophyletic, and we provide robust resolution for the relationships among these clades for the first time. These relationships can be used as a framework for addressing a variety of evolutionary questions (e.g. phylogeography, polyploidization, diversification, trait evolution, comparative genomics) for which Cypriniformes is ideally suited.
