The Biodiverse Rotifers (Rotifera: Eurotatoria) of the Floodplain Wetlands of Barak Valley of Assam, Northeast India
Opusc. Zool. Budapest, 2019, 50(1): 03–15 The biodiverse rotifers (Rotifera: Eurotatoria) of the floodplain wetlands of Barak valley of Assam, Northeast India B.K. SHARMA*, S. SHARMA Bhushan Kumar Sharma & Sumita Sharma Department of Zoology, North-Eastern Hill University, Shillong - 793 022, Meghalaya, India; *[email protected] (corresponding author) Abstract. The present analysis of alpha diversity of Rotifera of the floodplain wetlands of Barak valley, south Assam, northeast India (NEI) reveals 170 species, belonging to 39 genera and 19 families, with three species new to the Indian sub-region and two species new to Assam state. The rich and diverse rotifer assemblages comprise ~70%, ~57% and ~39% of total species of the Phylum known till date from Assam, NEI and India, respectively and thus affirm habitat and ecological heterogeneity of the Barak River floodplain wetlands. The elements of global biogeographic importance include one Australasian, eight Oriental, 10 Paleotropical, one Indo-Chinese, one cosmo (sub) tropical and four other species, and ~37% species merit regional distribution interest for India with ~13% exclusively reported from NEI. Lecanidae (~30%) and Brachionidae ≈ Lepadellidae (~32%) largely contribute to the rotifer richness; Trichocercidae > Testudinellidae are notable (~15%), and Notommatidae, Euchlanidae, Mytilinidae, Trichotriidae and Trochosphaeridae collectively form 16.5%. Lecane is the most speciose genus; Lepadella > Brachionus = Trichocerca include ~32% species, while Testudinella > Keratella deserve mention. Rotifera of the Barak floodplains exhibit the littoral-periphytonic nature, several small sized species and tropical character. Keywords. Barak River, biodiversity, composition, important taxa, richness, south Assam. INTRODUCTION river basin of south Assam (known as Barak valley) which is yet practically unexplored with otifera or Rotatoria, an integral component of regards to rotifer fauna (Sharma & Sharma R aquatic metazoans, have been recorded from 2014a). -

During the last eight decades, fewer than 80 publications have dealt specifically with sessile rotifers, while more than 7600 articles have focused on rotifers in general. In this work research on the sessile rotifers with emphasis on the Mexican fauna has been reviewed and some additional information on the new records has been included. Difficulties involved in collection and maintenance of sessile rotifers, as well as problems of identification and quantification have been considered. Published data on the ecology and taxonomy of this group has also been reviewed. There are 35 species of sessile rotifers from three families Atrochidae, Collothecidae, and Flosculariidae, but to that four more species in the planktonic family Conochilidae may be added, as recent molecular research indicates that this family lies within Flosculariidae. -

E-mail: [email protected] 3Corresponding author Abstract In response to a clear gap in knowledge on the biodiversity of sessile Gnesiotrocha rotifers at both global as well as re- gional Southeast Asian scales, we performed a study of free-living colonial and epiphytic rotifers attached to fifteen aquat- ic plant species in Thale Noi Lake, the first Ramsar site in Thailand. We identified 44 different taxa of sessile rotifers, including thirty-nine fixosessile species and three planktonic colonial species. This corresponds with about 40 % of the global sessile rotifer diversity, and is the highest alpha-diversity of the group ever recorded from a single lake. The record further includes a new genus, Lacinularoides n. gen., containing a single species L. coloniensis (Colledge, 1918) n. comb., which is redescribed, and several possibly new species, one of which, Ptygura thalenoiensis n. spec. is formally described here. Ptygura noodti (Koste, 1972) n. comb. is relocated from Floscularia, based on observations of living specimens of this species, formerly known only from preserved, contracted specimens from the Amazon region. -
Towards a Management Hierarchy (Classification) for the Catalogue of Life
TOWARDS A MANAGEMENT HIERARCHY (CLASSIFICATION) FOR THE CATALOGUE OF LIFE Draft Discussion Document Rationale The Catalogue of Life partnership, comprising Species 2000 and ITIS (Integrated Taxonomic Information System), has the goal of achieving a comprehensive catalogue of all known species on Earth by the year 2011. The actual number of described species (after correction for synonyms) is not presently known but estimates suggest about 1.8 million species. The collaborative teams behind the Catalogue of Life need an agreed standard classification for these 1.8 million species, i.e. a working hierarchy for management purposes. This discussion document is intended to highlight some of the issues that need clarifying in order to achieve this goal beyond what we presently have. Concerning Classification Life’s diversity is classified into a hierarchy of categories. The best-known of these is the Kingdom. When Carl Linnaeus introduced his new “system of nature” in the 1750s ― Systema Naturae per Regna tria naturae, secundum Classes, Ordines, Genera, Species …) ― he recognised three kingdoms, viz Plantae, Animalia, and a third kingdom for minerals that has long since been abandoned. As is evident from the title of his work, he introduced lower-level taxonomic categories, each successively nested in the other, named Class, Order, Genus, and Species. The most useful and innovative aspect of his system (which gave rise to the scientific discipline of Systematics) was the use of the binominal, comprising genus and species, that uniquely identified each species of organism. Linnaeus’s system has proven to be robust for some 250 years. The starting point for botanical names is his Species Plantarum, published in 1753, and that for zoological names is the tenth edition of the Systema Naturae published in 1758. -

About the Book the Format Acknowledgments
About the Book For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes. Having reached the age when I could retire whenever I wanted to, I no longer needed be so concerned with the publish or perish paradigm. In keeping with the sharing nature of bryologists, and the need to educate the non-bryologists about the nature and role of bryophytes in the ecosystem, it seemed my personal goals could best be accomplished by publishing online. This has several advantages for me. I can choose the format I want, I can include lots of color images, and I can post chapters or parts of chapters as I complete them and update later if I find it important. Throughout the book I have posed questions. I have even attempt to offer hypotheses for many of these. It is my hope that these questions and hypotheses will inspire students of all ages to attempt to answer these. Some are simple and could even be done by elementary school children. Others are suitable for undergraduate projects. And some will take lifelong work or a large team of researchers around the world. Have fun with them! The Format The decision to publish Bryophyte Ecology as an ebook occurred after I had a publisher, and I am sure I have not thought of all the complexities of publishing as I complete things, rather than in the order of the planned organization. -

On the Serotonergic Nervous System of Two Planktonic Rotifers, Conochilus Coenobasis and C
ARTICLE IN PRESS Zoologischer Anzeiger 245 (2006) 53–62 www.elsevier.de/jcz On the serotonergic nervous system of two planktonic rotifers, Conochilus coenobasis and C. dossuarius (Monogononta, Flosculariacea, Conochilidae) Rick Hochbergà Department of Biological Sciences, University of Massachusetts, One University Avenue, Lowell, MA 01854, USA Received 21 November 2005; received in revised form 4 April 2006; accepted 10 April 2006 Corresponding editor: M. Schmitt Abstract The serotonergic nervous systems of two non-colonial species of Conochilus were examined to obtain the first immunohistochemical insights into the neuroanatomy of species of Flosculariacea (Rotifera, Monogononta). Species of Conochilus, subgenus Conochiloides, were examined using serotonin (5-HT) immunohistochemistry, epifluorescence and confocal laser scanning microscopy, and 3D computer imaging software. In specimens of C. coenobasis and C. dossuarius, the serotonergic nervous system is defined by a dorsal cerebral ganglion, apically directed cerebral neurites, and paired nerve cords. The cerebral ganglion contains approximately four pairs of small 5-HT- immunoreactive perikarya; one pair innervates the posterior nerve cords and three pairs innervate the apical field. The most dorsal pair innervates a coronal nerve ring that encircles the apical field. Within the apical field is a second nerve ring that outlines the inner border of the coronal cilia. Together, both the inner and outer nerve rings may function to modulate ciliary activity of the corona. The other two pairs of perikarya innervate a region around the mouth. Specific differences in the distribution of serotonergic neurons between species of Conochilus and previously examined ploimate rotifers include the following: (a) a lack of immunoreactivity in the mastax; (b) a greater number of apically directed serotonergic neurites; and (c) a complete innervation of the corona in both species of Conochilus. -
New Records of 13 Rotifers Including Bryceella Perpusilla Wilts Et Al., 2010 and Philodina Lepta Wulfert, 1951 from Korea

The Rotifers of Spanish Reservoirs: Ecological, Systematical and Zoogeographical Remarks
91 THE ROTIFERS OF SPANISH RESERVOIRS: ECOLOGICAL, SYSTEMATICAL AND ZOOGEOGRAPHICAL REMARKS Jordi de Manuel Barrabin Departament d'Ecologia, Universitat de Barcelona. Avd. Diagonal 645,08028 Barcelona. Spain,[email protected] ABSTRACT This article covers the rotifer data from a 1987/1988 survey of one hundred Spanish reservoirs. From each species brief infor- mation is given, focused mainly on ecology, morphology, zoogeography and distribution both in Spain and within reservoirs. New autoecological information on each species is also established giving conductivity ranges, alkalinity, pH and temperature for each. Original drawings and photographs obtained on both optical and electronic microscopy are shown of the majority of the species found. In total one hundred and ten taxa were identified, belonging to 101 species, representing 20 families: Epiphanidae (1): Brachionidae (23); Euchlanidae (1); Mytilinidae (1 ): Trichotriidae (3): Colurellidae (8); Lecanidae (1 5); Proalidae (2); Lindiidae (1); Notommatidae (5); Trichocercidae (7); Gastropodidae (5); Synchaetidae (1 1); Asplanchnidae (3); Testudinellidae (3); Conochiliidae (5):Hexarthridae (2); Filiniidae (3); Collothecidae (2); Philodinidae (Bdelloidea) (I).
