Alien plant invasions—incorporating emerging invaders in regional prioritization: A pragmatic approach for Southern Africa
Plant invasions are a serious threat to natural and semi-natural ecosystems worldwide. Most management-orientated research on invasions focuses on invaders that are already widespread and often have major impacts. This ...
Key traits in a threatened butterfly and its common sibling: implications for conservation
(Springer Science+Business Media B.V, 2007)
We ask here which traits predispose one species to extreme rarity and possible extinction while a sympatric sibling is geographically widespread. With background knowledge on the level of habitat specialization of the ...
The distribution and spread of the invasive alien common myna Acridotheres tristis L. (Aves: Sturnidae), in southern Africa
(Academy of Science of South Africa, 2007-11)
The common myna is an Asian starling that has become established in many parts of the world outside of its native range due to accidental or deliberate introductions by humans. The South African population of this species ...
Craniometric sexual dimorphism and age variation in the South African Cape dune mole-rat (Bathyergus Suillus)
(American Society of Mammalogists, 2007)
Because absolute mammalian age is difficult to measure directly, various methods have been used for its estimation. Among these methods, the degree of molar eruption and wear are considered to be the most reliable indicators ...
Effects of experimental harvesting on recruitment of an alien mussel Mytilus galloprovincialis
Successful fisheries management is underpinned by an understanding of the processes that underlie the population dynamics of exploited stocks. This study considered the effects of experimental harvesting on recruitment of ...
Two new relict Syncordulia species found during museum and field studies of threatened dragonflies in the Cape Floristic Region (Odonata: Corduliidae)
(Magnolia Press, 2007)
Red List assessments often require the verification of records and taxonomy in museum collections and the field. Such research during an assessment of threatened dragonflies in the Cape Floristic Region (CFR) biodiversity ...
Rescuing the extinction of experience
(Springer Science+Business Media B.V., 2007)
Environmental Effects on Coleoptera Diversity in the Maloti-Drakensberg Region
A general paucity of studies on the dynamics of invertebrate assemblages exists despite the pivotal role that they play in ecosystem functioning. Altitude and season play vital roles in determining the composition of ...
Coalescence methods reveal the impact of vicariance on the spatial genetic structure of Elephantulus edwardii (Afrotheria, Macroscelidea)
(Blackwell Publishing, 2007)
Within the Macroscelidea 15 species of elephant-shrews are recognized, of which nine occur in the southern African subregion. The Cape rock elephant-shrew ( Elephantulus edwardii ) is the only strictly endemic South ...
The ecological dynamics of the invasive alien Common Myna Acridotheres tristis, L (Aves: Sturnidae) in South Africa
Urbanisation and invasive alien species constitute two of the most severe threats to biodiversity conservation in the 21st century. It is particularly concerning that these two threats often occur sympatrically and work ...
