Vascular Plant Survey of Vwaza Marsh Wildlife Reserve, Malawi
YIKA-VWAZA TRUST RESEARCH STUDY REPORT N (2017/18) Vascular Plant Survey of Vwaza Marsh Wildlife Reserve, Malawi By Sopani Sichinga ([email protected]) September , 2019 ABSTRACT In 2018 – 19, a survey on vascular plants was conducted in Vwaza Marsh Wildlife Reserve. The reserve is located in the north-western Malawi, covering an area of about 986 km2. Based on this survey, a total of 461 species from 76 families were recorded (i.e. 454 Angiosperms and 7 Pteridophyta). Of the total species recorded, 19 are exotics (of which 4 are reported to be invasive) while 1 species is considered threatened. The most dominant families were Fabaceae (80 species representing 17. 4%), Poaceae (53 species representing 11.5%), Rubiaceae (27 species representing 5.9 %), and Euphorbiaceae (24 species representing 5.2%). The annotated checklist includes scientific names, habit, habitat types and IUCN Red List status and is presented in section 5. i ACKNOLEDGEMENTS First and foremost, let me thank the Nyika–Vwaza Trust (UK) for funding this work. Without their financial support, this work would have not been materialized. The Department of National Parks and Wildlife (DNPW) Malawi through its Regional Office (N) is also thanked for the logistical support and accommodation throughout the entire study. Special thanks are due to my supervisor - Mr. George Zwide Nxumayo for his invaluable guidance. Mr. Thom McShane should also be thanked in a special way for sharing me some information, and sending me some documents about Vwaza which have contributed a lot to the success of this work. I extend my sincere thanks to the Vwaza Research Unit team for their assistance, especially during the field work. -

Schmitz1 and Vera L. S. Valente2 1 Universidade Federal da Integração-Latino-Americana, Foz do Iguaçu, PR, Brazil; [email protected] 2 Programa de Pós-Graduação em Genética e Biologia Molecular, Universidade Federal do Rio Grande do Sul, Porto Alegre, RS, Brazil; [email protected] Abstract Diptera is a megadiverse order, reaching its peak of diversity in Neotropics, although our knowledge of dipteran fauna of this region is grossly deficient. This applies even for the most studied families, as Drosophilidae. Despite its position of evidence, most aspects of the biology of these insects are still poorly understood, especially those linked to natural communities. Field studies on drosophilids are highly biased to fruit-breeders species. Flower-breeding drosophilids, however, are worldwide distributed, especially in tropical regions, although being mostly neglected. The present paper shows results of a biodiversity inventory of flower-breeding drosophilids carried out in Brazil, based on samples of 125 plant species, from 47 families. Drosophilids were found in flowers of 56 plant species, of 18 families. The fauna discovered showed to be highly unknown, comprising 28 species, 12 of them (>40%) still undescribed. -
The Age of Chocolate: a Diversification History of Theobroma and Malvaceae

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. We also demonstrate that Theobroma cacao, the source of chocolate, diverged from its most recent common ancestor 9.9 (7.7–12.9 [95% HPD]) Ma, in the Edited by: Federico Luebert, mid-to late-Miocene, suggesting that this economically important species has had ample Universität Bonn, Germany time to generate significant within-species genetic diversity that is useful information Reviewed by: for a developing chocolate industry. -

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. -

A total of 13 species belonging to 11 genera were recorded at BAUBG; out of these, the occurrence of 5 species is rare in nature/wild. Habits of the 13 species were different and the number of trees was 8, shrubs were 3 and herbs were 2. The conservation status, ethnobotanical uses e.g. medicinal, ornamental, food, fodder, etc. and phenology of these species have been presented here. Results of this study would be helpful to the BAUBG authority to set up their collection priority to conserve (threatened) plants species of this family. -

It was earlier University of Gottingen, Germany [1]. Byttneria Roxb. placed in Sterculiaceae and then a separate family was first placed in Sterculiaceae, then a separate family Byttneriaceae. As per APG classification, it is now treated Byttneriaceae. As per Angiosperm Phylogeny in family Malvaceae. Endemic taxa are usually more Group-APG-IV [2] classification Byttneria is now vulnerable to anthropogenic threats, natural and climate included in the family Malvaceae of Malvales clade. The changes, and therefore hold a higher extinction risk. Malvales clade also includes Malvaceae, Tiliaceae, Taxonomic study on endemic taxa improves a basic Bombacaceae, Bixaceae, Cistaceae, Cochlospermaceae, understanding for correct identification and description. Diegodendraceae, Dipterocarpaceae, Mutingiaceae, Habitat and distribution study are essential to get specific Neuradaceae, Sarcolaenaceae and Thymelaeaceae [2-4]. information and interpretation on current status and Finding of Judd and Manchester [5], Alverson, et al., [6] population dynamics of the taxon including niche and Bayer, et al., [4] has led to the proposal to combine requirements.
