Killer whale ecotypes: is there a global model?
(Cambridge Philosophical Society, 2013)Killer whales, Orcinus orca, are top predators occupying key ecological roles in a variety of ecosystems and are one of the most widely distributed mammals on the planet. In consequence, there has been significant interest ... -
Lack of human-assisted dispersal means Pueraria montana var. lobata (kudzu vine) could still be eradicated from South Africa
(Springer, 2016)The legume, Pueraria montana var. lobata (kudzu vine) is one of the worst plant invaders globally. Here we present the first study of P. montana in South Africa. We found only seven P. montana populations covering an ... -
Latitudinal and longitudinal barriers in global biogeography
(The Royal Society, 2006)Due to changes in climate and continental arrangement, plant and animal assemblages faced different dispersal barriers at different moments in Earth’s history. It is generally accepted that groups which diversified ... -
Life on the edge: rare and restricted episodes of a pan-tropical mutualism adapting to drier climates
(New Phytologist Trust, 2011)• The fig tree–fig wasp obligate pollination mutualism has strong ancestral affinities with tropical communities, but is present in much drier contemporary biomes, especially at higher latitudes at the edge of their range. ... -
Life table parameters of the woolly whitefly Aleurothrixus floccosus (Hemiptera: Aleyrodidae) and its parasitoid Cales noacki (Hymenoptera: Aphelinidae)
(Czech Academy of Sciences, 2014-05-05)Biological parameters of the woolly whitefly Aleurothrixus floccosus (Hemiptera: Aleyrodidae) and its parasitoid Cales noacki (Hymenoptera: Aphelinidae) were determined at 25.0 ± 2.0°C, 50.0 ± 10.0% RH and a photoperiod ... -
Linking landscape futures with biodiversity conservation strategies in northwest Iberia - A simulation study combining surrogates with a spatio-temporal modelling approach
(2016-07-26)The most prominent factors inducing landscape change in the rural regions of south west Europe are depopulation and the associated socio-ecological modifications. The aimof this work was to assess the future implications ... -
Livestock predation in South Africa: The need for and value of a scientific assessment
(Academy of Science of South Africa, 2017) -
Long after the event, or four things we (should) know about bird invasions
(Springer, 2015)The most significant single event in the study of alien bird invasions occurred in 1981, with the publication of John L. Long’s seminal book ‘‘ Introduced birds of the world’’ (full title: Introduced birds of the world: ... -
Macroecology of global bryophyte invasions at different invasion stages
(John Wiley & Sons Ltd, 2015)In this study we provide the first comprehensive assessment of the environmental and anthropogenic factors driving bryophyte invasions worldwide. We compiled data of alien bryophyte distributions from 82 regions on five ... -
Managing conflict-generating invasive species in South Africa: Challenges and trade-offs
(AOSIS, 2017)Background: This paper reviewed the benefits and negative impacts of alien species that are currently listed in the Alien and Invasive Species Regulations of the National Environmental Management: Biodiversity Act (Act no ... -
Measuring size and composition of species pools: a comparison of dark diversity estimates
(John Wiley & Sons Ltd., 2016)Ecological theory and biodiversity conservation have traditionally relied on the number of species recorded at a site, but it is agreed that site richness represents only a portion of the species that can inhabit particular ... -
Mind the gaps: investigating the cause of the current range disjunction in the Cape Platanna, Xenopus gilli (Anura: Pipidae)
(Open Access, 2013-09-26)Low-lying areas of the Cape at Africa’s south-westernmost tip have undergone dramatic marine-remodelling, with regular changes in sea-level following glacial cycles. Species for which marine barriers are impenetrable ... -
Modelling the effect of two biocontrol agents on the invasive alien tree Acacia cyclops - Flowering, seed production and agent survival
(Elsevier, 2014-04-24)Invasive alien plants play an important role in our changing world and have a considerable negative impact on ecosystems in many parts of the world. One effective control strategy involves the use of biocontrol agents which ... -
Monitoring consumptive resource use in South African national parks
(AOSIS, 2019)Monitoring is an essential component of measuring the performance of protected areas. This requirement led to the development of a biodiversity monitoring system for South African National Parks (SANParks). The system ... -
Mountain roads and non-native species modify elevational patterns of plant diversity
(John Wiley & Sons Ltd, 2018)Aim: We investigated patterns of species richness and community dissimilarity along elevation gradients using globally replicated, standardized surveys of vascular plants. We asked how these patterns of diversity are ... -
Mutualism between armoured scale insects and ants: new species and observations on a unique trophobiosis (Hemiptera: Diaspididae; Hymenoptera: Formicidae: Melissotarsus Emery)
(The Royal Entomological Society, 2013)The association between African armoured scale insects (Hemiptera: Coccoidea: Diaspididae) and ants belonging to Melissotarsus Emery (Hymenoptera: Formicidae: Myrmicinae) is the only trophobiosis known in which ants do not ... -
Mycorrhizal status helps explain invasion success of alien plant species
(Ecological Society of America, 2017)It is still debated whether alien plants benefit from being mycorrhizal, or if engaging in the symbiosis constrains their establishment and spread in new regions. We analyzed the association between mycorrhizal status of ... -
Native-range habitats of invasive plants: are they similar to invaded-range habitats and do they differ according to the geographical direction of invasion?
(John Wiley & Sons Ltd, 2015)Aim Habitat types are involved in shaping biological traits of their resident native species and thus they determine, to a large extent, in which habitats particular species will succeed if invading outside their native ... -
Naturalization of central European plants in North America: species traits, habitats, propagule pressure, residence time
(Ecological Society of America, 2015)The factors that promote invasive behavior in introduced plant species occur across many scales of biological and ecological organization. Factors that act at relatively small scales, for example, the evolution of biological ...
