Generalist southern African temperate forest canopy tree species have distinct pollinator communities partially predicted by floral traits

open access: yesAustral Ecology, Volume 49, Issue 5, May 2024.
Pollination systems of tall forest trees are poorly studied, resulting from the difficulties in observing pollinator activity at canopy level and great temporal variation in flower production. Here, we observed insect flower visitors, at canopy level, to four southern Afrotemperate forest tree species bearing small, white to green flowers in a large ...

Invasion of an Afrotemperate forest complex by the polyphagous shot hole borer beetle

open access: yesEntomologia Experimentalis et Applicata, Volume 172, Issue 4, Page 354-369, April 2024.
Polyphagous shot hole borer, Euwallacea fornicatus (Coleoptera: Curculionidae, Scolytinae), is a serious invasive tree‐killing pest that has not been studied in natural forest systems. We determined the drivers of PSHB colonization in 1682 trees (68 species) in a native Afrotemperate forest.

Proximate content and lipid profile of seeds from rapanea melanophloeos (the Cape beech) tree [PDF]

open access: yes, 2017
: Rapanea melanophloeos (Cape beech) is a fruit-bearing tree indigenous to Southern Africa which produces edible fruit. Previous studies have focussed on investigating the nutritional potential of the tree’s fruit pulp.

New ophiostomatoid fungi from wounds on storm-damaged trees in Afromontane forests of the Cape Floristic Region

open access: yes, 2020
Ophiostomatoid fungi, a well-known tree-associated group, include some of the most important forest pathogens globally. Several ophiostomatoid species were reported already from Rapanea melanophloeos of the Afromontane forests from the Cape Floristic ...

Selected South African plants with tyrosinase enzyme inhibition and their effect on gene expression [PDF]

open access: yes, 2019
Hyperpigmentation causes patches of skin to blemish and may lead to serious skin disorders. Prevention of hyperpigmentation would require suppressing the melanogenesis pathway which uses the rate limiting enzyme tyrosinase.

Disturbance ecology and size class structure of the Mulanje cedar of Malawi, Widdringtonia whytei and associated broadleaved forest [PDF]

open access: yes, 2010
The disturbance ecology and regeneration patterns of the emergent conifer, Widdringtonia whytei, and five broadleaved species, Aphloia theiformis, Rapanea melanophloeos, Maesa lanceolata, Maytenus accuminata and Psychotria mahonii, were inferred from ...

Light microsite requirements of seedlings of some Afromontane forest tree species: the role of canopy gaps promoting regeneration [PDF]

open access: yes, 2017
Predictions of microsite requirements for seven common Afromontane forest tree species were made by testing above ground relative growth rate (RGR) and photosynthetic response of seedlings of the respective species under different light intensities ...

Predicting the post-fire responses of two forest tree precursors after an autumn fire in mountain fynbos [PDF]

open access: yes, 1993
This study investigated whether post-fire survival of two fynbos forest precursors Rapanea melanophloeos (L). Mez and Kiggelaria afri.cana L. were dependent on plant size or fire intensity.

Anthelmintic activity of preparations derived from Myrsine africana and Rapanea melanophloeos against the nematode parasite, Haemonchus contortus, of sheep

open access: yes, 2013
Myrsine africana L. and Rapanea melanophloeos L. belong to the plant family Myrsinaceae. Various rural communities in Kenya, such as smallholder farmers and pastoralists, use them to treat their livestock.
