Plant species diversity in cape fynbos: Gamma and delta diversity

  title={Plant species diversity in cape fynbos: Gamma and delta diversity},
  author={Frederick John Kruger and H. C. Taylor},
This paper reports the number of plant species on circumscribed fynbos areas (gamma diversity), ranging in size from 0.27 km2 (a site with 364 species) to 471 km2 (2351 species). The composition of the floras of four of these sites was analysed to measure delta diversity, the change in flora from one site to the next. Maximum gamma diversity values fitted a species-area curve log S=2.69+0.25 log A. Gamma diversity is apparently higher than in any of the world's biogeographic zones except… 
Patterns of plant species diversity in fynbos vegetation, South Africa
In fynbos vegetation of the southwestern Cape Province, South Africa, plant species diversity relations (alpha and beta diversity) are studied in a local context of variation across two interacting
Why is the Cape Peninsula so rich in plant species? An analysis of the independent diversity components
High beta diversity, encompassing almost complete turnover, was recorded along soil fertility gradients, and future research should focus on developing a biological and ecological understanding of the different forms of rarity and integrating this into management plans for the maintenance of biodiversity.
Plant Diversity of the Cape Region of Southern Africa
Species richness of the Cape flora is hypothesized to be the result of geographic and parapatric radiation in an area with a mosaic of different habitats due to local soil, climate, and altitudinal differences that combine to produce steep ecological gradients.

Comprising a land area of ca 90000 km2, less than 4% of the total land area for the Southern African subcontinent, the Cape Floristic Province is one of the world's richest areas in terms of
Diversity relations in Cape shrublands and other vegetation in the southeastern Cape, South Africa
This paper investigates, and seeks explanations for, the diversity relations of Cape shrublands (fynbos and renosterveld), subtropical thicket and Afromontane forest, in the biogeographically complex
Geographic variation in plant species richness patterns within temperate eucalypt woodlands of eastern Australia
If local woodland richness is maintained by low pattern diversity and greater habitat connectedness then larger reserves are required in order to maintain the largest area of contiguous habitat, and pattern diversity was strongly correlated to the coldest minimum winter temperatures.
Management of critically endangered renosterveld fragments in the Overberg, South Africa
Quartz fields are islands of distinct vegetation in southern Africa. Such habitats differ from surrounding shale substrate in geomorphological and climatic attributes, and are dominated by a

There is a great need for experimental testing of the proposed speciation mechanisms, more molecular clock estimates of the age and pattern of the radiations, and more fossil evidence bearing on the past climates.
The Cape Peninsula, South Africa: physiographical, biological and historical background to an extraordinary hot-spot of biodiversity
The Cape Peninsula, a 470 km2 area of rugged scenery and varied climate, is located at the southwestern tip of the Cape Floristic Region, South Africa. The Peninsula is home to 2285 plant species and


Plant species diversity and ecological districts of the Sinai desert

It is suggested that the high gamma diversity of Sinai is primarily due to its environmental heterogeneity, being a meeting place of three phytogeographical regions and to past climatic changes.
Maximum Plant Species Diversity in Terrestrial Communities
This hypothesis that some non-forest sclerophyll communities like the fynbosch of the Cape Peninsula of South Africa and similar communities in Australia may be even more species-rich is suggested and tested for the first time using previously unavailable data.
A vegetation survey of the Cape of Good Hope Nature Reserve. I. The use of association-analysis and Braun-Blanquet methods*
The synthetic phytosociological Braun-Blanquet method provides a more natural classification of plant communities of the Cape of Good Hope Nature Reserve than does the monothetic divisive association-analysis method.
Cape Hangklip area. II. The vegetation
Various habitat factors influencing the fynbos vegetation of the Cape Hangklip area, such as topography, geology, soil and climate and historical features, are outlined. Data collected at 250

Island Biogeography Theory and Conservation Practice
The application of island biogeography theory to conservation practice is premature because a major conclusion of such applications—that refuges should always consist of the largest possible single area—can be incorrect under a variety of biologically feasible conditions.

Not only is the distribution lognormal, but the constants or parameters seem to be restricted in a peculiar way, and they are not fixed, but they are interlocked.
