Lasiosiphon rigidus, a new species from the Tankwa Karoo and two new combinations in the genus for South Africa
(MDPI, 2013)
Thymelaeaceae are well represented in southern
Africa, with ± 190 species in nine genera (Bredenkamp
& Beyers 2000; Beaumont et al. 2009). Preliminary
phylogenetic analyses of nuclear and plastid DNA
sequences (Van der ...
Phylogenetic position and revised classification of Acacia s.l. (Fabaceae: Mimosoideae) in Africa, including new combinations in Vachellia and Senegalia
(Oxford University Press, 2013)
Previous phylogenetic studies have indicated that Acacia Miller s.l. is polyphyletic and in need of reclassification.
A proposal to conserve the name Acacia for the larger Australian contingent of the genus (formerly ...
Will climate warming exceed lethal photosynthetic temperature thresholds of lichens in a southern African arid region?
(Wiley, 2013)
Predicted elevated temperatures and a shift from a winter to summer rainfall pattern associated with global warming could result in the exposure of hydrated lichens during summer to more numerous temperature extremes that ...
Biodiversity: so much more than legs and leaves
(AOSIS OpenJournals, 2013)
Microorganisms inhabit virtually every possible niche on Earth, including those at the outer envelope of survival. However, the focus of most conservation authorities and ecologists is the ‘legs and leaves’ side of biology ...
Diet of whale sharks Rhincodon typus inferred from stomach content and signature fatty acid analyses
(Inter Research, 2013)
Whale sharks Rhincodon typus are large filter-feeders that are frequently observed
feeding in surface zooplankton patches at their tropical and subtropical coastal aggregation sites.
Using signature fatty acid (FA) ...
An insight into the reproductive biology of the bearded goby Sufflogobius bibarbatus
(Wiley, 2013)
Preliminary results obtained from histological analyses of the male reproductive organs, supplemented
with field and behavioural data, indicate that Sufflogobius bibarbatus, a small, slow growing
gobiid exhibiting low ...
Beyond the jellyfish joyride and global oscillations: advancing jellyfish research
(Oxford University Press, 2013)
There has been debate in the literature recently about increases in jellyfish populations in response to anthropogenic change, and this has attracted widespread media interest. Despite an international collaborative ...
Abundance and species composition of non-geniculate coralline red algae epiphytic on the South African populations of the rocky shore seagrass Thalassodendron leptocaule M.C. Duarte, Bandeira & Romeiras
(Elsevier, 2013)
Seagrasses support a great diversity of epiphytic organisms and new research has
shown that non-geniculate coralline red algae are important occupiers of space on
the fronds of seagrasses. Except for a few scant records, ...
Comparing community structure on shells of the abalone Haliotis midae and adjacent rock: implications for biodiversity
(Springer Verlag, 2013)
This paper concerns the effects on biodiversity of depletion 24 of the South African
abalone Haliotis midae, which is a long-lived species with a large corrugated shell
that provides a habitat for diverse benthic organisms. ...
Self-maintaining or continuously refreshed? The genetic structure of Euphausia lucens populations in the Benguela upwelling ecosystem
(Oxford University Press, 2013)
Populations of Euphausia lucens over the shelf of the southern Benguela upwelling region could be self-maintaining. Alternatively, they could be continually refreshed by expatriates from the SW Atlantic that enter the ...
