  • Complete Chloroplast Genome Sequence of the Mangrove Species Kandelia Obovata and Comparative Analyses with Related Species
    Complete chloroplast genome sequence of the mangrove species Kandelia obovata and comparative analyses with related species Yong Yang1, Ying Zhang2, Yukai Chen1, Juma Gul1, Jingwen Zhang1, Qiang Liu1 and Qing Chen3 1 Ministry of Education Key Laboratory for Ecology of Tropical Islands, College of Life Sciences, Hainan Normal University, Haikou, China 2 Life Sciences and Technology School, Lingnan Normal University, Zhanjiang, China 3 Bawangling National Nature Reserve, Changjiang, Hainan Province, China ABSTRACT As one of the most cold and salt-tolerant mangrove species, Kandelia obovata is widely distributed in China. Here, we report the complete chloroplast genome sequence K. obovata (Rhizophoraceae) obtained via next-generation sequencing, compare the general features of the sampled plastomes of this species to those of other sequenced mangrove species, and perform a phylogenetic analysis based on the protein-coding genes of these plastomes. The complete chloroplast genome of K. obovata is 160,325 bp in size and has a 35.22% GC content. The genome has a typical circular quadripartite structure, with a pair of inverted repeat (IR) regions 26,670 bp in length separating a large single-copy (LSC) region (91,156 bp) and a small single-cope (SSC) region (15,829 bp). The chloroplast genome of K. obovata contains 128 unique genes, including 80 protein-coding genes, 38 tRNA genes, 8 rRNA genes and 2 pseudogenes (ycf1 in the IRA region and rpl22 in the IRB region). In addition, a simple sequence repeat (SSR) analysis found 108 SSR loci in the chloroplast genome of K. obovata, most of which are A/T rich.

  • MANGROVES of KERALA P
    MANGROVES OF KERALA p. Kaladharan and P.K. Asokan Cahcut Research Centre of CMFRI.. West Hill PO, Kozhikode-673005 Mangroves plants are salt tolerant plants of tropical and subtropical intertidal regions of the world. These highly adapted plants have many peculiar features than their terrestrial and aquatic counterparts. The word ‘mangrove’ can also be used to describe the habitat as well as the plants. Mangroves are distributed in the tropical countries of the world. The mangrove ecosystem covers only 0,037 per cent of the world's surface or 0.12 per cent of the Earth’s land area. Mangroves in India account for about 5 percent of the world’s mangrove vegetation and are spread over an area of about 4,500 km 2 along the coastal States/UTs of the country. Sunderbans in West Bengal accounts for a little less than half of the total area under mangroves in India. In Kerala, only Kannur district has good natural patches. There were approximately 755 hectare of mangrove forest in Kannur However, it has now become reduced to 17 km I Forest Survey of India (FSI, 2003) furti'ier showed that mangrove vegetation in Kerala is now restncted largely to river mouths and tidal creeks and that there has been no significant mangrove cover to the south of Cochin, TABLE 1 List of Mangrove vegetation found in Kerala S.No Family G enus Species Local name 1 Myrsinaceae Aegiceros corniculatum pookandal 2 Acanthaceae Avicennia officinalis uppotti Acanthaceae Avicennia manna cheruuppoUi 4 Acanthaceae Acanthus ilicifolius chuilikandal 5 Rhizophoraceae Rhizophora

  • The Composer's Guide to the Tuba
    THE COMPOSER’S GUIDE TO THE TUBA: CREATING A NEW RESOURCE ON THE CAPABILITIES OF THE TUBA FAMILY Aaron Michael Hynds A Dissertation Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of DOCTOR OF MUSICAL ARTS August 2019 Committee: David Saltzman, Advisor Marco Nardone Graduate Faculty Representative Mikel Kuehn Andrew Pelletier © 2019 Aaron Michael Hynds All Rights Reserved iii ABSTRACT David Saltzman, Advisor The solo repertoire of the tuba and euphonium has grown exponentially since the middle of the 20th century, due in large part to the pioneering work of several artist-performers on those instruments. These performers sought out and collaborated directly with composers, helping to produce works that sensibly and musically used the tuba and euphonium. However, not every composer who wishes to write for the tuba and euphonium has access to world-class tubists and euphonists, and the body of available literature concerning the capabilities of the tuba family is both small in number and lacking in comprehensiveness. This document seeks to remedy this situation by producing a comprehensive and accessible guide on the capabilities of the tuba family. An analysis of the currently-available materials concerning the tuba family will give direction on the structure and content of this new guide, as will the dissemination of a survey to the North American composition community. The end result, the Composer’s Guide to the Tuba, is a practical, accessible, and composer-centric guide to the modern capabilities of the tuba family of instruments. iv To Sara and Dad, who both kept me going with their never-ending love.

Microtopographical measurements, quantitative data on vegetation, and propagule counts were collected in Gazi Bay (Kenya) and utilized in a ‘geographical information systems’ (GIS) environment where all modelling took place based on digital terrain modelling (DTM). Suitability maps were created for propagules of Rhizophora mucronata and Ceriops tagal to analyse the disper- sal possibilities (through stranding or self-planting) for the present situation, and for cases of degra- dation and sea level change. The GIS-analyses take into account the available information derived from the field data, but alterations that go hand in hand with degradation and/or sea level changes (e.g.
