Field soil respiration rate on a Sub-Antarctic island : its relation to site characteristics and response to added C, N and P
(Scientific Research Publishing Inc, 2012-06)Botanical, soil chemistry and soil microbiology variables were tested as predictors of in situ soil respiration rate in the various terrestrial habitats on sub-Antarctic Marion Island (47oS, 38oE). Inorganic P and total N ... -
A fine-scale assessment of the ecosystem service-disservice dichotomy in the context of urban ecosystems affected by alien plant invasions
(SpringerOpen (part of Springer Nature), 2019)Background: Natural resources within and around urban landscapes are under increasing pressure from ongoing urbanisation, and management efforts aimed at ensuring the sustainable provision of ecosystem services (ES) are ... -
Fine-scale biogeography : tidal elevation strongly affects population genetic structure and demographic history in intertidal fishes
(University of California, eScholarship, 2013)Numerous studies have demonstrated population genetic structuring in marine species, yet few have investigated the effect of vertical zonation on gene flow and population structure. Here we use three sympatric, closely ... -
Fire ecology -- Cape fynbos biome
(Fire management -- Cape Fynbos biome, 2013)The management of fire-dependent biodiversity hotspots must be based on sound ecological knowledge and a pragmatic approach that accommodates the constraints within which fire managers must operate. South Africa’s fynbos ... -
Fire regimes in eastern coastal fynbos : imperatives and thresholds in managing for diversity
(AOSIS Publishing, 2013)Until recently, fire ecology was poorly understood in the eastern coastal region of the Cape Floral Kingdom (CFK), South Africa. Rainfall in the area is aseasonal and temperatures are milder than in the winter-rainfall and ... -
First abundance estimates of heaviside’s (cephalorhynchus heavisidii) and dusky (lagenorhynchus obscurus) dolphins off namibia using a novel visual and acoustic line transect survey
(Frontiers Media, 2020)Knowledge of a population’s abundance is of primary importance for conservation management. However, robust estimates of abundance are often difficult to obtain, especially for cetaceans which spend most of their lives ... -
First finding of the parasitic fungus Hesperomyces virescens (Laboulbeniales) on native and invasive ladybirds (Coleoptera, Coccinellidae) in South Africa
(EDP Sciences, 2016)Hesperomyces virescens is a fungal ectoparasite (Laboulbeniales) that infects adult ladybirds. Research has recently focused on this parasite due to the discovery of its prevalence on the globally invasive harlequin ladybird ... -
Fluff-thieving birds sabotage seed dispersal
(Royal Society, 2016)Characterizing many species interactions as mutualisms can be misleading because some members of the interaction derive greater fitness benefits at the expense of other members. We provide detailed natural history data on ... -
Four New Bat Species (Rhinolophus hildebrandtii Complex) Reflect Plio-Pleistocene Divergence of Dwarfs and Giants across an Afromontane Archipelago
(PLOS, 2012-09-12)Gigantism and dwarfism evolve in vertebrates restricted to islands. We describe four new species in the Rhinolophus hildebrandtii species-complex of horseshoe bats, whose evolution has entailed adaptive shifts in body size. ... -
Frequency and intensity of facilitation reveal opposing patterns along a stress gradient
(Wiley Open Access, 2018)ENGLISH ABSTRACT: Disentangling the different processes structuring ecological communities is a long‐standing challenge. In species‐rich ecosystems, most emphasis has so far been given to environmental filtering and ... -
Frog eat frog : exploring variables influencing anurophagy
(PeerJ, 2015)Background - Frogs are generalist predators of a wide range of typically small prey items. But descriptions of dietary items regularly include other anurans, such that frogs are considered to be among the most important ... -
From biological control to controlling biology

From Chile to the South African west coast : first reports of the Chilean stone crab Homalaspis plana (H. Milne Edwards, 1834) and the South American sunstar Heliaster helianthus (Lamarck, 1816) outside their natural ranges
(Regional Euro-Asian Biological Invasions Centre, 2018-10-01)The South American multiradiate sunstar Heliaster helianthus (Lamarck, 1816) and the Chilean stone crab Homalaspis plana (H. Milne Edwards, 1834) are marine predators that, previous to this report, have no invasion history. ... -
Frontiers of Biogeography : taking its place as a journal of choice for the publication of high quality biogeographical research articles
(International Biogeography Society, 2018)Through this editorial we seek your support and engagement as authors, readers and reviewers as we take the next steps in developing Frontiers of Biogeography as a leading international journal of biogeography and ... -
Functional responses of a cosmopolitan invader demonstrate intraspecific variability in consumer-resource dynamics
(PeerJ, 2018)Background. Variability in the ecological impacts of invasive species across their geographical ranges may decrease the accuracy of risk assessments. Comparative functional response analysis can be used to estimate invasive ... -
Fusarium inhibition by wild populations of the medicinal plant Salvia africana-lutea L. linked to metabolomic profiling
(BioMed Central, 2014-03)Abstract Background: Salvia africana-lutea L., an important medicinal sage used in the Western Cape (South Africa), can be termed a ‘broad-spectrum remedy’ suggesting the presence of a multiplicity of bioactive metabolites. ... -
The fynbos and succulent Karoo biomes do not have exceptional local ant richness
(Public Library of Science (PLoS), 2012-03)Background: The Fynbos (FB) and Succulent Karoo biomes (SKB) have high regional plant diversity despite relatively low productivity. Local diversity in the region varies but is moderate. For insects, previous work suggests ... -
Gastropods alien to South Africa cause severe environmental harm in their global alien ranges across habitats
(Wiley Open Access, 2018)Alien gastropods have caused extensive harm to biodiversity and socioeconomic systems like agriculture and horticulture worldwide. For conservation and management purposes, information on impacts needs to be easily ... -
Genetic analysis shows low levels of hybridization between African wildcats (Felis silvestris lybica) and domestic cats (F. s. catus) in South Africa
(John Wiley & Sons Ltd., 2015)Hybridization between domestic and wild animals is a major concern for biodiversity conservation, and as habitats become increasingly fragmented, conserving biodiversity at all levels, including genetic, becomes increasingly ... -
Genetic and biophysical models help define marine conservation focus areas
(Frontiers Media, 2018-08-06)Ecological and environmental variables play a major role in the genetic structure of marine populations, but how oceanography affects their dispersal and associated connectivity remains far from being understood. To account ...
