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 ...
Colonisation of sub-Antarctic Marion Island by a non-indigenous aphid parasitoid Aphidius matricariae (Hymenoptera, Braconidae)
Over the past two decades seven non-indigenous vascular plant or arthropod species have established reproducing populations at sub-Antarctic Marion Island (46°54'S, 37°55'E). Here we record the eighth establishment, a ...
Genetic and morphological comparisons of a potentially invasive weed (Argemone ochroleuca) from its natural (Mexico) and invaded (South Africa) habitat
Morphological and genetic comparisons of a potentially invasive weed (Argemone ochroleuca) from its natural (Mexico) and invaded (South Africa) habitats are presented. Seeds from 14 Mexican and 13 South African populations ...
Population structure, propagule pressure, and conservation biogeography in the sub-Antarctic: lessons from indigenous and invasive springtails
(BLACKWELL PUBLISHING, 2007-08)
The patterns in and the processes underlying the distribution of invertebrates among Southern Ocean islands and across vegetation types on these islands are reasonably well understood. However, few studies have examined ...
Genetic evidence confirms the origin of the house mouse on sub-Antarctic Marion Island
Biological invasions and climate change are two of the largest threats to biodiversity, and this is especially true for island ecosystems that have largely evolved in isolation. The house mouse is considered to have been ...
Phylogeography of Eupodes minutus (Acari : Prostigmata) on sub-Antarctic Marion Island reflects the impact of historical events
Marion Island, situated similar to 2,300 km south-east of Cape Town, South Africa, has experienced multiple volcanic and glaciation events during its history. To better understand the impact of these events on species' ...
