Constancea 83.15: SEAWEED COLLECTIONS, NATURAL HISTORY MUSEUM 12/17/2002 06:57:49 PM Constancea 83, 2002 University and Jepson Herbaria P.C. Silva Festschrift Marine Algal (Seaweed) Collections at the Natural History Museum, London (BM): Past, Present and Future Ian Tittley Department of Botany, The Natural History Museum, London SW7 5BD ABSTRACT The specimen collections and libraries of the Natural History Museum (BM) constitute an important reference centre for macro marine algae (brown, green and red generally known as seaweeds). The first collections of algae were made in the sixteenth and seventeenth centuries and are among the earliest collections in the museum from Britain and abroad. Many collectors have contributed directly or indirectly to the development and growth of the seaweed collection and these are listed in an appendix to this paper. The taxonomic and geographical range of the collection is broad and a significant amount of information is associated with it. As access to this information is not always straightforward, a start has been made to improve this through specimen databases and image collections. A collection review has improved the availability of geographical information; lists of countries for a given species and lists of species for a given country will soon be available, while for Great Britain and Ireland geographical data from specimens have been collated to create species distribution maps. This paper considers issues affecting future development of the seaweed collection at the Natural History Museum, the importance and potential of the UK collection as a resource of national biodiversity information, and participation in a global network of collections. -

E-mail: [email protected] Abstract An ongoing phycological survey in the Laje de Santos Marine State Park (LSMSP) of São Paulo in southeastern Brazil revealed a previously undescribed species of Osmundea (Rhodophyta, Rhodomelaceae), which was found in the subtidal zone at a depth of 7 to 20 m. Morphological studies conducted on Osmundea specimens collected in the LSMSP revealed characteristics typical of the genus Osmundea, including two pericentral cells per each axial segment and tetrasporangia cut off randomly from cortical cells. -

Rhodomelaceae, Rhodophyta) Based on Molecular Analyses and Morphological Observations of Specimens from the Type Locality in Western Australia

Email: [email protected] Abstract Considerable uncertainty surrounds the phylogenetic position of Polysiphonia scopulorum, a species with an apparently cos- mopolitan distribution. Here we report, for the first time, molecular phylogenetic analyses using plastid rbcL gene sequences and morphological observations of P. scopulorum collected from the type locality, Rottnest Island in Western Australia. Mor- phological characteristics of the Rottnest Island specimens allowed unequivocal identification, however, the sequence analy- ses uncovered discrepancies in previous molecular studies that included specimens identified as P. scopulorum from other locations. The phylogenetic evidence clearly revealed that P. scopulorum from Rottnest Island formed a sister clade with P. caespitosa from Spain (JX828149 as P. scopulorum) with moderate support, but that it differed from specimens identified as P. scopulorum from the U.S.A. (AY396039, EU492915). In light of this, we suggest that P. scopulorum be considered an endemic species with a distribution restricted to Australia. -
Martensia Fragilis Harv. (Delesseriaceae): a New Record to Seaweed Flora of Karnataka Coast, India
J. Algal Biomass Utln. 2018, 9(2): 55-58 Martensia fragilis: A New record to seaweed flora of Karnataka Coast eISSN: 2229 – 6905 Martensia fragilis Harv. (Delesseriaceae): A New record to seaweed flora of Karnataka Coast, India. S.K. Yadav and M Palanisamy* Botanical Survey of India, Southern Regional Centre, Coimbatore - 641 003, Tamil Nadu, India.* Corresponding author: [email protected] Abstract Comprehensive marine macro algal explorations conducted in Karnataka coast during the years 2014-2017 revealed new distributional record of a red algae Martensia fragilis Harv. (Delesseriaceae). A complete description, nomenclatural citations and notes on its occurance have been provided. Keywords: New Record, Martensia fragilis Harv., Karnataka coast, Seaweeds, Rhodophyceae. Introduction The marine macro algae, also known as seaweeds, are the important component of the marine floral diversity. The red seaweed genus Martensia K. Hering belongs to the family Delesseriaceae under the order Ceramiales of class Rhodophyceae. Presently, this genus is represented with 18 taxa in the world (Guiry & Guiry, 2018), and 2 taxa in India (Rao & Gupta, 2015). It is mostly distributed in the tropical to subtropical regions of the world and is characterised by membranous thallus with flabellate lobes. Martensia fragilis Harv. was first described by Harvey in 1854 from the Belligam Bay, Ceylon (now Weliagama, Sri Lanka). Silva & al. (1996) reported this species from the Maldives. Later, it was reported by various workers from other parts of the world like Australia (Huisman, 1997), Africa (Ateweberhan & Prud’homme 2005), South Korea (Lee, 2006), Pacific islands (Skelton & South, 2007), China (Zheng & al., 2008), New Zealand (Nelson, 2012), Vietnam (Nguyen & al., 2013), Taiwan (Lin, 2013), Philippines (Kraft & al. -

Diversity and Distribution of Seaweeds from the West Coast of Maharashtra
J. Algal Biomass Utln. 2017, 8(3): 29- 39 Distribution of Seaweeds from the West Coast of Maharashtra eISSN: 2229 – 6905 Diversity and Distribution of Seaweeds from the West Coast of Maharashtra Waghmode A.V Department of Botany, Rajarshi Chh. Shahu College, Kadamwadi, Kolhapur-416004. E-mail: [email protected] Abstract The purpose of this research is to introduce the diversity of algal flora along the west coast of Maharashtra. The present study of seaweeds was conducted at west coast of Maharashtra formed of different inter-tidal rock shores with rich algal vegetation. During the study period (Aug 2015 to Feb 2016), total 73 species of seaweeds were recorded. An updated species list has been compiled on the basis of fresh collections. Of these 21 species belong to Chlorophyta, 17 species to Phaeophyta and 33 species to Rhodophyta. Among them, Blue-green algae like Lyngbya, Microcoleus were found all over the west coast. Red algae were found more, then the green and brown from the west coast of Maharashtra. Caulerpa spp were observed only at Sindhudurgh and Raighad district. S. ilicifolium were found commonly throughout the west coast. Keywords: Diversity, Seaweeds distribution, Maharashtra coast Introduction Algae are the most common marine vegetation commonly called “Seaweeeds”. They are classified into Blue-green (Cyanophyta), Green (Chlorophyta), Brown (Phaeophyta) and Red (Rhodophyta). Seaweeds play important role in marine food chains. It is suggested that seaweeds could become a major food and energy resource in the 21st century. Biodiversity is the variety among living organisms and the ecological complexes in which they occur. -
