The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage. -

Reproductive Ecology of Bird-Pollinated Babiana (Iridaceae): Floral Variation, Mating Patterns and Genetic Diversity
REPRODUCTIVE ECOLOGY OF BIRD-POLLINATED BABIANA (IRIDACEAE): FLORAL VARIATION, MATING PATTERNS AND GENETIC DIVERSITY by Caroli de Waal A thesis submitted in conformity with the requirements for the degree of Master of Science Department of Ecology and Evolutionary Biology University of Toronto © Copyright by Caroli de Waal 2010 REPRODUCTIVE ECOLOGY OF BIRD-POLLINATED BABIANA (IRIDACEAE): FLORAL VARIATION, MATING PATTERNS AND GENETIC DIVERSITY Caroli de Waal Master of Science Department of Ecology and Evolutionary Biology University of Toronto 2010 Abstract Flowering plants possess striking variation in reproductive traits and mating patterns, even among closely related species. In this thesis, I investigate morphological variation, mating and genetic diversity of five taxa of bird-pollinated Babiana (Iridaceae), including two species with specialized bird perches. Field observations in 12 populations demonstrated that sunbirds were the primary pollinators. Babiana ringens exhibited correlated geographic variation in flower and perch size. Controlled field pollinations revealed self-compatibility and low pollen limitation in B. ringens subspecies, and self-incompatibility and chronic pollen limitation in B. hirsuta. Allozyme markers demonstrated moderate to high selfing rates among populations and considerable variation in levels of genetic diversity. In B. ringens there was a positive relation between the geographic and genetic distance of populations. The results of a manipulative field experiment indicated position-dependent herbivory on inflorescences of B. hirsuta and this could play a role in the evolution of specialized bird perches in Babiana. ii Acknowledgments First, I would like to thank my supervisor Spencer Barrett for his wealth of knowledge, his contagious enthusiasm about the natural world, and for pushing me further than I thought I could go. -

Newsletter No. 4 Autumn 2005
The Southern African Bulb Group Newsletter No. 4 Autumn 2005 The Southern African Bulb Group was initiated by a group of enthusiasts on April 4th 2004. The objective of the group is to further the understanding of the cultivation of Southern African bulbs, where `bulbs' is used in the broad sense to encompass bulb-, corm- and tuber- possessing Southern African plants, including `dicots' such as Oxalis. In the first instance the group will be run on an informal basis, with an initial subscription of £5 invited from participants. Committee: Robin Attrill (Membership secretary and Newsletter editor), Margaret Corina (Treasurer), Stefan Rau and Terry Smale Editorial This issue of the newsletter contains a report of the meeting of the group held at Rupert Bowlby's Nursery on April 9th 2005, an article on Crinum moorei by David Corina, information on recent literature of interest to growers of Southern African bulbs, and an updated list of suppliers of seed and bulbs/corms of Southern African geophytes. In addition a balance sheet covering the first year of operation of the group is attached. With respect to the supplier list, please let me know if you are aware of other sources which should be included. As I have previously stated the group welcomes articles, and suggestions, for inclusion in future newsletters. Contributions (hand/typewritten and electronic are acceptable!) are urgently required and should be sent to the newsletter editor at 17 Waterhouse Moor, Harlow, Essex, CM18 6BA (Email [email protected] ) Publication of the next issue is scheduled for December 2005. Report on visit to Rupert Bowlby - Saturday 9 th April 2005 by David Corina About 20 members attended the event, and the Group would like to thank Rupert for his hospitality at the event and for opening his collection to the public gaze. -
