Patterns of Plant Diversity and Endemism in Namibia
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Stellenbosch University SUNScholar Repository Bothalia 36,2: 175-189(2006) Patterns of plant diversity and endemism in Namibia P. CRAVEN* and P VORSTER** Keywords: Namibia, phytogeography, plant endemism ABSTRACT Species richness, endemism and areas that are rich in both species and endemic species were assessed and mapped for Namibia. High species diversity corresponds with zones where species overlap. These are particularly obvious where there are altitudinal variations and in high-lying areas. The endemic flora o f Namibia is rich and diverse. An estimated 16% of the total plant species in Namibia are endemic to the country. Endemics are in a wide variety o f families and sixteen genera are endemic. Factors that increase the likelihood o f endemism are mountains, hot deserts, diversity o f substrates and microclimates. The distribution of plants endemic to Namibia was arranged in three different ways. Firstly, based on a grid count with the phytogeographic value of the species being equal, overall endemism was mapped. Secondly, range restricted plant species were mapped individually and those with congruent distribution patterns were combined. Thirdly, localities that are important for very range-restricted species were identified. The resulting maps of endemism and diversity were compared and found to correspond in many localities. When overall endemism is compared with overall diversity, rich localities may consist o f endemic species with wide ranges. The other methods identify important localities with their own distinctive complement of species. INTRODUCTION (1994). It was based on distributional data per magiste rial district following Merxmiiller (1966-1972), as well Species diversity was traditionally measured by count as other literature. -

This study aims to predict the impact of bioclimatic variables in current and future climatic scenarios on the distribution of Inuleae tribe species. Modeling the distribution of 30 species of the Inuleae tribe in Algeria was carried out with a maximum entropy model. Two models with 99 occurrence points were obtained with mean values of Area Under a Curve (AUC) of 0.987±0.01 and 0.971±0.02, reflecting excellent predictive power. Three bioclimatic variables contributed mainly to the first model and four - to the second one with cumulative contributions of 83.8% and 79%, respectively elucidating differences between species of the two major climatic zones in Algeria: the Tell and the Sahara. Two-dimensional niches of Algerian Inuleae species allowed to distinguish these two groups with the distribution of 18 Tell species, characterized by high rainfall (14-18°C, 400-1000 mm) and the other 12 species – distributed in hot and dry environments (17-24°C, 20-200 mm). Modeling the distribution under future conditions showed that habitats of the Saharan region would be much less suitable for these species with a variation in the annual mean temperature increase up to 20% and a decrease in annual precipitation, which could raise to 11 and 15%. -

Wasps and Bees in Southern Africa
SANBI Biodiversity Series 24 Wasps and bees in southern Africa by Sarah K. Gess and Friedrich W. Gess Department of Entomology, Albany Museum and Rhodes University, Grahamstown Pretoria 2014 SANBI Biodiversity Series The South African National Biodiversity Institute (SANBI) was established on 1 Sep- tember 2004 through the signing into force of the National Environmental Manage- ment: Biodiversity Act (NEMBA) No. 10 of 2004 by President Thabo Mbeki. The Act expands the mandate of the former National Botanical Institute to include respon- sibilities relating to the full diversity of South Africa’s fauna and flora, and builds on the internationally respected programmes in conservation, research, education and visitor services developed by the National Botanical Institute and its predecessors over the past century. The vision of SANBI: Biodiversity richness for all South Africans. SANBI’s mission is to champion the exploration, conservation, sustainable use, appreciation and enjoyment of South Africa’s exceptionally rich biodiversity for all people.

Naturforsch. 60c, 671Ð678 (2005); received May 19, 2005 Three members of the tribe Gnaphalieae and six members of the tribe Inuleae (Astera- ceae) were analyzed for their exudate flavonoids. Whereas some species exhibit rather trivial flavonoids, others produce rare compounds. Spectral data of rare flavonoids are reported and their structural identification is discussed. 6-Oxygenation of flavonols is a common feature of two Inula species and Pulicaria sicula. By contrast, flavonoids with 8-oxygenation, but lacking 6-oxygenation, are common in two out of three Gnaphalieae species examined. In addition, B-ring deoxyflavonoids are abundantly present in the leaf exudates of Helichrysum italicum (Gnaphalieae). These distinctive features of the two Asteraceae tribes are in agreement with previous flavonoid surveys of these and related taxa.
