2013-12-31 Assembly and disassembly of bird pollination communities at the Cape of Africa

Geerts, Sjirk (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: With the current global decline in pollinators, and the concurrent decline in plant species, pollination research is becoming increasingly important. However, studies outside Europe and North-America and ...
Ancient forest fragmentation or recent radiation? Testing refugial speciation models in chameleons within an African biodiversity hotspot

Tolley K.A. Tilbury C.R. Measey G.J. Menegon M. Branch W.R. Matthee C.A. (2011)

Aim East Africa is one of the most biologically diverse regions, especially in terms of endemism and species richness. Hypotheses put forward to explain this high diversity invoke a role for forest refugia through: (1) ...
Chameleons on the move: Survival and movement of the cape dwarf chameleon, bradypodion pumilum, within a fragmented Urban habitat

Tolley K.A. Raw R.N.V. Altwegg R. Measey G.J. (2010)

Reptiles have an amazing diversity of life-history attributes ranging from the shortest- to longest-lived of vertebrate species. Estimating survival in wild populations is of key importance when understanding population ...
Geo-information pyramids for up-to-date and flexible conservation plans: A case study for Transfrontier Conservation Areas

Smith N. De Klerk H. (2007)

The initiative to link habitat and parks across political borders, to form large Transfrontier Conservation Areas (TFCAs), has gained momentum in Africa and the world. TFCAs hold many advantages, one of them being the ...
Using scale-area curves to quantify the distribution, abundance and range expansion potential of an invasive species

Veldtman R. Chown S.L. McGeoch M.A. (2010)

Aim Invasive species distribution and abundance data are essential for management decisions on mitigating impacts but is seldom available. Here, we use scale-area curves to assess the distribution, abundance and consequent ...
Woody plant communities of isolated Afromontane cloud forests in Taita Hills, Kenya

Aerts R. Thijs K.W. Lehouck V. Beentje H. Bytebier B. Matthysen E. Gulinck H. Lens L. Muys B. (2011)

In the Taita Hills in southern Kenya, remnants of the original Afromontane forest vegetation are restricted to isolated mountain peaks. To assess the level of degradation and the need for forest restoration, we examined ...
