Pollen Morphology of Indian Species of Saraca L. (Leguminosae)-A Threatened and Legendary Medicinal Tree

Email: [email protected]; [email protected]. Abstract: The genus Saraca L. (Leguminosae) is a universal panacea in herbal medicine. The present study investigates the comparative pollen morphology of four species of Saraca viz. S. asoca (Roxb.) de Wilde, S. declinata (Jack) Miq., S. indica L., and S. thaipingensis Cantley ex Prain growing in India to reveal differences of their pollen structures to aid taxonomic and evolutionary values. The detailed morphology and surface structure of pollen grains were studied and described using light microscopy and scanning electron microscopy. The pollen grains of Saraca showed isopolar, para-syncolporate, tricolporate, with radially symmetric, prolate and prolate-spheroidal structure. The surface of pollen of S. indica is rugulate with large lirae but in S. declinata, the surface is micro-rugulate to vermiculate with relatively thin lirae and that of S. thaipingensis is indistinct as the psilate surface with a frequent protuberance and fewer perforations were observed along with the gemmae like structure. Exine ornamentation helped to separate S. indica and S. asoca. Exine thickness varies from 3-4 μm. Presence of protuberance and exine thickness varies among individuals of the species spread over different locations. -

Investigating the Impact of Fire on the Natural Regeneration of Woody Species in Dry and Wet Miombo Woodland
Investigating the impact of fire on the natural regeneration of woody species in dry and wet Miombo woodland by Paul Mwansa Thesis presented in fulfilment of the requirements for the degree of Master of Science of Forestry and Natural Resource Science in the Faculty of AgriSciences at Stellenbosch University Supervisor: Prof Ben du Toit Co-supervisor: Dr Vera De Cauwer March 2018 Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. March 2018 Copyright © 2018 Stellenbosch University All rights reserved i Stellenbosch University https://scholar.sun.ac.za Abstract The miombo woodland is an extensive tropical seasonal woodland and dry forest formation in extent of 2.7 million km². The woodland contributes highly to maintenance and improvement of people’s livelihood security and stable growth of national economies. The woodland faces a wide range of disturbances including fire that affect vegetation structure. An investigation into the impact of fire on the natural regeneration of six tree species was conducted along a rainfall gradient. Baikiaea plurijuga, Burkea africana, Guibourtia coleosperma, Pterocarpus angolensis, Schinziophyton rautanenii and Terminalia sericea were selected on basis of being an important timber and/or utilitarian species, and the assumed abundance. The objectives of the study were to examine floristic composition, density and composition of natural regeneration; stand structure and vegetation cover within recently burnt (RB) and recently unburnt (RU) sections of the forest. -

Miombo Ecoregion Vision Report
MIOMBO ECOREGION VISION REPORT Jonathan Timberlake & Emmanuel Chidumayo December 2001 (published 2011) Occasional Publications in Biodiversity No. 20 WWF - SARPO MIOMBO ECOREGION VISION REPORT 2001 (revised August 2011) by Jonathan Timberlake & Emmanuel Chidumayo Occasional Publications in Biodiversity No. 20 Biodiversity Foundation for Africa P.O. Box FM730, Famona, Bulawayo, Zimbabwe PREFACE The Miombo Ecoregion Vision Report was commissioned in 2001 by the Southern Africa Regional Programme Office of the World Wide Fund for Nature (WWF SARPO). It represented the culmination of an ecoregion reconnaissance process led by Bruce Byers (see Byers 2001a, 2001b), followed by an ecoregion-scale mapping process of taxa and areas of interest or importance for various ecological and bio-physical parameters. The report was then used as a basis for more detailed discussions during a series of national workshops held across the region in the early part of 2002. The main purpose of the reconnaissance and visioning process was to initially outline the bio-physical extent and properties of the so-called Miombo Ecoregion (in practice, a collection of smaller previously described ecoregions), to identify the main areas of potential conservation interest and to identify appropriate activities and areas for conservation action. The outline and some features of the Miombo Ecoregion (later termed the Miombo– Mopane Ecoregion by Conservation International, or the Miombo–Mopane Woodlands and Grasslands) are often mentioned (e.g. Burgess et al. 2004). However, apart from two booklets (WWF SARPO 2001, 2003), few details or justifications are publically available, although a modified outline can be found in Frost, Timberlake & Chidumayo (2002). Over the years numerous requests have been made to use and refer to the original document and maps, which had only very restricted distribution. -
