  • Phylogeny of Trochetia Species Based on Morphological and Molecular Markers
    UIVERSITY OF MAURITIUS RESEARCH JOURAL – Volume 15 – 2009 University of Mauritius, Réduit, Mauritius Phylogeny of Trochetia species based on morphological and molecular markers K. Poorun Mauritius V. M. Ranghoo-Sanmukhiya* Faculty of Agriculture, University of Mauritius Email: [email protected] Paper Accepted on 27 October 2009 Abstract Trochetia is a genus of six species out of which five are endemic to Mauritius. Its taxonomic classification has been changed from the Sterculiaceae family to the Malvaceae recently. Molecular and morphological characterization was carried out for the five Trochetia species as a means to conserve endangered Trochetia species and to understand their genetic diversity. Hibiscus genevii and Dombeya mauritiana were also included in the study as outgroups to infer the phylogeny of Trochetia . A modified protocol was used for DNA extraction using CTAB. Morphological characterization was based on both quantitative and qualitative traits. Random Amplified Polymorphic DNA (RAPD) technique was used for assessing genetic diversity of Trochetia species. High levels of polymorphism were noted among the Trochetia species using RAPD markers. Both molecular and morphological data were cladistically analyzed using the unweighted pair group method with arithmetic average (UPGMA) based on Jaccard’s coefficient. Cluster analysis revealed two different phylogenies of Trochetia for the two different markers used. T. triflora was found to have more similar features to D. mauritiana as compared to its congeneric species, as evident from the dendogram based on morphological characters. Out of the twenty nine morphological characters used, T. triflora bears four characters similar to D. mauritiana as compared to the other Trochetia species. Moreover, both T.

  • Neighbors Gone, Fruits Gone, Species Gone 19 March 2007
    Neighbors gone, fruits gone, species gone 19 March 2007 In an experiment carried out in 2003 and 2004 and reported in the April issue of the American Naturalist, Hansen and coworkers could show that Trochetia plants growing close to Pandanus patches had a higher chance of being pollinated and produce fruit than plants further away. Thus, Trochetia enters an indirect dependency with its neighbor Pandanus via the geckos. "The case of Trochetia and its pollinator is only one of many examples of the complexity and fragility of island community interactions. When an island ecosystem is altered by humans, the outcome for both plants and animals are hard to predict. We need field experiments such as this one to understand the potentially disastrous effects," says Christine Müller. "There has been a long tradition of studying direct interactions in pollination biology," says Dennis Hansen, "but only little focus on indirect interactions, even though they often have Phelsuma cepediana visiting a Trochetia flower for large effects. Our study illustrates how important it nectar. Photograph by Dennis Hansen is to know as much as possible about the community-level interactions of an endangered species before deciding on conservation management. Who would have thought that to Neighbors gone, sex gone, fruits gone, species conserve Trochetia blackburniana we would end up gone.

An explanation for greater Neotropical diversity compared to other parts of the tropics is that it was an accident of the Andean orogeny. Using dated phylogenies, of chloroplast ndhF and nuclear DNA WRKY sequence datasets, generated using BEAST we demonstrate that the diversification of the genera Theobroma and Herrania occurred from 12.7 (11.6–14.9 [95% HPD]) million years ago (Ma) and thus coincided with Andean uplift from the mid-Miocene and that this lineage had a faster diversification rate than other major clades in Malvaceae.

  • A New Species and Hybrid in the St Helen a Endemic Genus Trochetiopsis
    EDINB. 1. BOT. 52 (2): 205-213 (1995) 205 A NEW SPECIES AND HYBRID IN THE ST HELEN A ENDEMIC GENUS TROCHETIOPSIS Q. C. B. CRONK * The discovery in historic herbaria of an overlooked extinct endemic from the island of St Helena is reported. The first descriptions of St Helena Ebony, Trochetiopsis melanoxylon (Sterculiaceae), and the specimens associated with them in the herbaria of Oxford University (OXF) and the Natural History Museum, London (BM), do not match living and later-collected material, and instead represent an extinct plant. A new name is therefore needed for living St Helena Ebony: Trochetiopsis ebenus Cronk sp. nov. The hybrid between this species and the related T erythroxylon is also described here: Trochetiopsis x benjamini Cronk hybr. nov. (Sterculiaceae), and chromosome counts of 2n =40 are reported for the hybrid and both parents for the first time. The re-assessment of the extinct ebony emphasizes the importance of historic herbarium collections for the study of species extinction. INTRODUCTION In 1601 and 1610, at the beginning and end of his voyage to the East Indies, Franvois Pyrard de Laval touched at St Helena, an isolated island in the South Atlantic Ocean. He wrote: 'Sur Ie haut de la montagne il y a force arbre d'Ebene, et de bois de Rose' (Pyrard, 1679; Gray, 1890) - the first mention in print of species of Trochetiopsis (i.e. St Helena Redwood and St Helena Ebony). The island was settled in 1659, and the settlers of the English East India Company immediately put these ecologically important species to use.

S.L. and Taxonomic Revision of Genus Abutilon Mill. in Saudi Arabia Wafaa Kamal Taia Alexandria University, Faculty of Science, Botany Department, Alexandria, Egypt [email protected] Abstract. This works deals with the recent opinions about the new classification of the core Malvales with special reference to the family Malvaceae s.l. and the morphological description and variations in the species of the genus Abutilon Mill. Taxonomical features of the family as shown in the recent classification systems, with full description of the main divisions of the family. Position of Malvaceae s.l. in the different modern taxonomical systems is clarified. General features of the genus Abutilon stated according to the careful examination of the specimens. Taxonomic position of Abutilon in the Malvaceae is given. Artificial key based on vegetative morphological characters is provided. Keywords: Abutilon, Core Malvales, Eumalvaceae, Morpholog, Systematic Position, Taxonomy. General Features of Family Malvaceae According to Heywood[1] and Watson and Dallwitz[2] the plants of the family Malvaceae s.s. are herbs, shrubs or trees with stipulate, simple, non-sheathing alternate or spiral, petiolate leaves usually with palmate vennation (often three principal veins arising from the base of the leaf blade). Plants are hermaphrodite, rarely dioecious or poly-gamo- monoecious with floral nectarines and entomophilous pollination. Flowers are solitary or aggregating in compound cymes, varying in size from small to large, regular or somewhat irregular, cyclic with distinct calyx and corolla.

Nat. 2007, 169(4):534-42 Positive indirect interactions between neighboring plant species via a lizard pollinator Abstract In natural communities, species are embedded in networks of direct and indirect interactions. Most studies on indirect interactions have focused on how they affect predator-prey or competitive relationships. However, it is equally likely that indirect interactions play an important structuring role in mutualistic relationships in a natural community. We demonstrate experimentally that on a small spatial scale, dense thickets of endemic Pandanus plants have a strong positive trait-mediated indirect effect on the reproduction of the declining endemic Mauritian plant Trochetia blackburniana.

The nearest relatives are a group or “genus” of shrubs called Dombeya , common in Madagascar but also found in southern Tropical Africa, and a further genus called Trochetia which occurs in Mauritius. It is probable that Dombeya -like plants (see Figure 1), were once much more widespread across Africa, but many of their descendents now flourish only on remote outposts in the Atlantic and Indian Oceans (Figure 2).
