The species composition and the plankton quotients show the t\<IO lakes are mesotrophic.Host of the algae seen are well-lmown and widespread .. L~i.crasterins Hard;x:j:. G .. S .. West has only been recorded from Australia. INTRODUCTION Lakes Hume and Mulwala, parts of the Murray River (fig.1) Victoria, are near the boarder of Victoria and N.S.W. The aims of this study are three-folded: 1) to identify most of the phytoplankton species in both lakes, 2) to determine the trophic status of both lakes from the species composition and the phytoplankton quotients, 3) to survey the geographical distribution of the desmids seen .. The algae will be identify solely from their morphology. Attempts will be made to put them into existing taxa. In recent years advances have been made on the identification of algae by the use of cultures and scanuing electron microscope. The latter is particularly useful in the case of 9psmariEm SR~ or the diatoms,etc. where the \vall structures are the taxonomic criterion (Lyon 1969). Culture experiments are use.ful when one wishes to delimit species .. MATERIALS AND HETHOD 20 (1974) Hume and 7 (1974) l!ulwala fixed samples as well as some live samples, all were collected by Hr .. R .. L.Croome with a 20 J.A. pore net at various stations shown in fig .. 1, were examined on a Carl Zeiss RA microscope fitted with a prism drawing system with internally reflected image, allowing binocular viewing while drawing. 1 (1968) Hume and 6 (1968-9) Mulwala fixed samples were also examined .. The 1974 samples were denoted as date/n~onth of collection. The numbers in brackets follo\,ring the Hume samples indicated the station numbers. All the 1968, 1969 samples were denoted by year/month/date/number of the sample. ~ ~\ \ilurray R Murre;· R r~ HI ~-·-_·'~·;,~~ } ~··~··:~ ~ ~Albury ~ ~- ~q -f( ~ Ru!herglen 09~-~i' l.

The idea of a meeting on everything about Volvox and its relatives (aka Volvocales or volvocine algae) reflects both an increase in the size of the Volvox community and the realization that many researchers from fields traditionally not associated with Volvox research (e.g., physics, theoretical biology) are interested in various aspects of the system. Indeed, volvocine algae have become an important model system for the evolution of multicellularity, development and cellular differentiation, and lately have yielded important results in fields as diverse as genomics, hydrodynamics, and social evolution. We hope that these meetings will continue to foster exchange of ideas and expertise, and will initiate new collaborations. Furthermore, with these meetings we wish to attract new people and to build a stronger Volvox community. CONFERENCE ORGANIZER Aurora M.

  • Green Algae and the Origins of Multicellularity in the Plant Kingdom
    Downloaded from http://cshperspectives.cshlp.org/ on October 8, 2021 - Published by Cold Spring Harbor Laboratory Press Green Algae and the Origins of Multicellularity in the Plant Kingdom James G. Umen Donald Danforth Plant Science Center, St. Louis, Missouri 63132 Correspondence: [email protected] The green lineage of chlorophyte algae and streptophytes form a large and diverse clade with multiple independent transitions to produce multicellular and/or macroscopically complex organization. In this review, I focus on two of the best-studied multicellular groups of green algae: charophytes and volvocines. Charophyte algae are the closest relatives of land plants and encompass the transition from unicellularity to simple multicellularity. Many of the innovations present in land plants have their roots in the cell and developmental biology of charophyte algae. Volvocine algae evolved an independent route to multicellularity that is captured by a graded series of increasing cell-type specialization and developmental com- plexity. The study of volvocine algae has provided unprecedented insights into the innova- tions required to achieve multicellularity. he transition from unicellular to multicellu- and rotifers that are limited by prey size (Bell Tlar organization is considered one of the ma- 1985; Boraas et al. 1998).
