Tackling invasive alien species in Europe: the top 20 issues
(Reabic, 2014)Globally, Invasive Alien Species (IAS) are considered to be one of the major threats to native biodiversity, with the World Conservation Union (IUCN) citing their impacts as ‘immense, insidious, and usually irreversible’. ... -
Taxonomic revision of the South African mealybug genus Octococcus Hall (Hemiptera: Pseudococcidae)
(Entomological Society of Southern Africa, 2016)A taxonomic revision of the South African mealybug genus Octococcus Hall is presented. Most species of this genus feed on plants in the Asteraceae. Six species are treated, namely, O. barbarae, O. gullanae. and O. warniae ... -
Temperate trees and shrubs as global invaders: the relationship between invasiveness and native distribution depends on biological traits.
(Springer, 2014)Many woody plants have been recently recognized as major invasive species with serious impacts on species diversity and functioning of invaded ecosystems. We evaluated the global invasion success of temperate trees and ... -
Temporal and interspecific variation in rates of spread for insect species invading Europe during the last 200 years
(Springer, 2016)Globalization is triggering an increase in the establishment of alien insects in Europe, with several species having substantial ecological and economic impacts. We investigated long-term changes in rates of species spread ... -
Tests of the mid-domain hypotheses: A review of the evidence
(Ecological Society of America, 2008)Geographic variation of species richness is strongly correlated with environmental gradients. However, random arrangement of species distributions within a bounded domain can also theoretically produce richness gradients ... -
Towards an integrative, eco-evolutionary understanding of ecological novelty: studying and communicating interlinked effects of global change
(2019)Global change has complex eco-evolutionary consequences for organisms and ecosystems, but related concepts (e.g., novel ecosystems) do not cover their full range. Here we propose an umbrella concept of “ecological novelty” ... -
Troubling travellers: are ecologically harmful alien species associated with particular introduction pathways?
(Pensoft, 2017)Prioritization of introduction pathways is seen as an important component of the management of biological invasions. We address whether established alien plants, mammals, freshwater fish and terrestrial invertebrates with ... -
Twenty-five years of conferences on the Ecology and Management of Alien Plant invasions: the history of EMAPi 1992-2017
(Springer, 2019)During the first 25 years, EMAPi conferences were attended by 1280 participants from 77 countries in five continents and produced 1474 presentations, including 44 keynotes on a broad range of aspects of plant invasion ... -
A unified classification on alien species based on the magnitude of their environmental impacts
(Public Library of Science, 2014-05-06)Species moved by human activities beyond the limits of their native geographic ranges into areas in which they do not naturally occur (termed aliens) can cause a broad range of significant changes to recipient ecosystems; ... -
Updated list of Collembola species currently recorded from South Africa
(Pensoft, 2015)Understanding the abundance and richness of species is one of the most fundamental steps in effecting their conservation. Despite global recognition of the significance of the below-ground component of diversity for ... -
Urban environments provide opportunities for early detections of Phytophthora invasions
(Springer, 2017)Globalization has increased the frequency of inadvertent introductions of plant pathogens. Many catastrophic invasions of both natural and agricultural systems have been initiated through anthropogenic dissemination ... -
Urban trees: bridge-heads for forest pest invasions and sentinels for early detection
(Springer, 2017)Urban trees have been increasingly appreciated for the many benefits they provide. As concentrated hubs of human-mediated movement, the urban landscape is, however, often the first point of contact for exotic pests including ... -
Using CT-scanning technology to quantify damage of the stem-boring beetle, Aphanasium australe, a biocontrol agent of Hakea sericea in South Africa
(2020)The stem-boring beetle, Aphanasium australe was introduced into South Africa in 2001 for biocontrol of Hakea sericea. It has a two-year life cycle, the majority of which is spent within the basal stem and roots of its host ... -
Using genetics to prioritise headwater stream fish populations of the Marico barb, Enteromius motebensis Steindachner 1894, for conservation action
(AOSIS, 2017)South Africa has a relatively large number of threatened freshwater fish species and limited resources to implement conservation programs. Enteromius motebensis was regionally prioritised for action because of its conservation ... -
Validation of the phenology model for the codling moth, Cydia pomonella (Lepidoptera: Tortricidae), in South African pome fruit orchards
(Entomological Society of Southern Africa, 2014)The codling moth, Cydia pomonella (Linnaeus) (Lepidoptera: Tortricidae), is a key pest of pome fruits in theWestern Cape, SouthAfrica. Up to 1993, the industry recommendation for commencement of the codling moth spray ... -
A vision for global monitoring of biological invasions
(Elsevier Ltd., 2017)Managing biological invasions relies on good global coverage of species distributions. Accurate information on alien species distributions, obtained from international policy and cross-border co-operation, is required to ... -
Weed risk assessments are an effective component of invasion risk management
(Wees Science Society of America(WSSA), 2016) -
Widely distribuded native and alien plant species differ in arbuscular mycorrhizal associations and related functional trait interactions
(Nordic Society Oikos, 2018)It is debated whether alien plants in new environments benefit from being mycorrhizal and whether widely distributed natives and aliens differ in their associations with mycorrhizal fungi. Here, we compared whether species ... -
The wildlife pet trade as a driver of introduction and establishment in alien birds in Taiwan
(Springer, 2016)The global trade in alien cage birds is flourishing and is considered to be one of the major routes by which species are entrained into the human-mediated invasion pathway. Here, we explore the likely influence of the ...
