Molecular Data and the Evolutionary History of Dinoflagellates by Juan Fernando Saldarriaga Echavarria Diplom, Ruprecht-Karls-Un
Molecular data and the evolutionary history of dinoflagellates by Juan Fernando Saldarriaga Echavarria Diplom, Ruprecht-Karls-Universitat Heidelberg, 1993 A THESIS SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE STUDIES Department of Botany We accept this thesis as conforming to the required standard THE UNIVERSITY OF BRITISH COLUMBIA November 2003 © Juan Fernando Saldarriaga Echavarria, 2003 ABSTRACT New sequences of ribosomal and protein genes were combined with available morphological and paleontological data to produce a phylogenetic framework for dinoflagellates. The evolutionary history of some of the major morphological features of the group was then investigated in the light of that framework. Phylogenetic trees of dinoflagellates based on the small subunit ribosomal RNA gene (SSU) are generally poorly resolved but include many well- supported clades, and while combined analyses of SSU and LSU (large subunit ribosomal RNA) improve the support for several nodes, they are still generally unsatisfactory. Protein-gene based trees lack the degree of species representation necessary for meaningful in-group phylogenetic analyses, but do provide important insights to the phylogenetic position of dinoflagellates as a whole and on the identity of their close relatives. Molecular data agree with paleontology in suggesting an early evolutionary radiation of the group, but whereas paleontological data include only taxa with fossilizable cysts, the new data examined here establish that this radiation event included all dinokaryotic lineages, including athecate forms. Plastids were lost and replaced many times in dinoflagellates, a situation entirely unique for this group. Histones could well have been lost earlier in the lineage than previously assumed. -

Plant-animal interaction has been a major theme in ecology as it has helped ecologists to rule out different patterns they observed in the surrounding environments. Chromolaena odorata is another plant species that is studied extensively as it has become a major troublesome weed in many parts of the tropics. But, handful of studies are available on pollination of this invasive plant species in dry forests and its function as a pollinator sink in these environments. The current study was carried out in a dry zone secondary forest patch in North-Central Sri Lanka to assess the diversity, abundance, and pollination strength of flower visitors associated with the C. -

A Catalogue of the Vespidae of the Malagasy Subregion (Insecta, Hymenoptera)
© Biologiezentrum Linz/Austria; download unter www.biologiezentrum.at Linzer biol. Beitr. 41/2 1871-1935 18.12.2009 A Catalogue of the Vespidae of the Malagasy Subregion (Insecta, Hymenoptera) 1 J.M. CARPENTER & M. MADL A b s t r a c t : We record 120 species and four subspecies of the family Vespidae from the Malagasy Subregion. The subfamily Eumeninae is represented by 44 species and four subspecies in 21 genera and the subfamily Polistinae by 67 species in three genera. The generic position of nine species is still unknown. New records for the islands of the southwest Indian Ocean are provided. Odynerus farquharensis CAMERON 1907 is transferred to the genus Knemodynerus BLÜTHGEN 1940 and Epiodynerus grandidieri limbatulus GIORDANI SOIKA 1991 to the genus Anterhynchium de SAUSSURE 1863, new combinations. K e y w o r d s : Vespidae, Malagasy Subregion, catalogue, taxonomy, new records. Introduction The Malagasy Subregion consists of a number of islands of quite different origins. Madagascar and the Seychelles (Inner Seychelles) are continental, while other islands are oceanic islands of volcanic (Comoros, Mayotte, Réunion, Mauritius, Rodrigues) or coralline origin (e. g. Aldabra, Amirantes, Agalega). These islands moreover show a greater range of ages than most other island regions. This diversity of islands, and the complex effects of land separation, emergence and habitat isolation, is responsible for an extraordinary biodiversity in the region, which is both largely endemic and highly threatened (habitat loss, invasive species). Inventory of the biota is an urgent priority, but is hampered by the scattered literature in many taxa. The wasp family Vespidae exemplifies these points. -
