Classification and dynamics of the forest vegetation of Hluhluwe Nature Reserve, Kwa Zulu-Natal

Author: West, Adam Date: 1996 The forests of Hluhluwe Nature Reserve, Kwa Zulu-Natal, were examined to determine composition, grain, classification, dynamics and conservation value. Field sampling took the form of recording DBH for all species in twenty-one 0.04 ha circular ... Read more
Experimental evidence for bird pollination and corolla damage by ants in the short-tubed flowers of Erica halicacaba (Ericaceae)

Author: Turner, R C ; Midgley, J J ; Barnard, P ; Simmons, R E ; Johnson, S D Date: 2012 Unrelated plants pollinated by similar animals tend to show convergent evolution of floral traits. Floral syndromes have been used successfully to develop hypotheses about pollination systems but can be misleading when plants have unusual ... Read more
How do fires kill plants? The hydraulic death hypothesis and Cape Proteaceae "fire-resisters"

Author: Midgley, J J ; Kruger, L M ; Skelton, R Date: 2011 The actual mechanism which causes plant death after having been burned has been poorly studied. One possibility is that fire causes direct, or indirect, fatal damage to plant hydraulic systems. If true, this suggests that burned plants ... Read more
Life-history evolution as an explanation for the absence of the tree life-form in Cape fynbos

Author: Midgley, J J ; Rebelo, A G Date: 2008 Invasive exotic trees are able to grow tall (more than 15 m) in the fynbos environment of the southwestern Cape of South Africa, whereas the tallest fynbos plants, generally from the Proteaceae, have much shorter maximum stature (less than 5 ...

No adverse signs of the effect of environmental change on tree biomass in the Knysna forest during the 1990s

Author: Midgley, J J ; Seydack, A Date: 2006 We analysed the growth of all trees greater than 10 cm diameter at breast height in 108 plots of 0.04 ha each in an unharvested nature reserve in the Knysna forest for the period 1991-2001. Gross growth rates (in-growth plus growth of survivors) ... Read more
Response to Matthews et al. (2001) vegetation of the Tembe Elephant Park, Maputaland, South Africa

Author: Kirkwood, D ; Midgley, J J Date: 2003 The contribution of Matthews et al. (2001) to our knowledge of the vegetation of Tembe Elephant Park (TEP) is both valuable and timely. Tembe is at the epicentre of the Maputaland Centre of Endemism (Van Wyk 1994), which, together with the ... Read more
Were Malagasy Uncarina fruits dispersed by the extinct elephant bird?

Author: Midgley, J J ; Illing, N Date: 2009 We hypothesise that the spiny fruits of the endemic Madagascar genus Uncarina (Pedaliaceae) are trample burrs that evolved to be dispersed on the feet of the extinct elephant bird (Aepyornis). Our evidence is : i) the morphology of the fruit ... Read more
Why do elephants damage savanna trees?

Author: Midgley, J J ; Balfour, D ; Kerley, G I Date: 2005 Elephants damage and kill trees. THIS behaviour often appears to be excessive because their immediate, subsequent consumption of edible parts of these trees is often negligible. Some trees later resprout after snapping and toppling by elephants ... Read more
