Unlocking the potential of Google Earth as a tool in invasion science
(Springer, 2014)
Distribution data are central to many
invasion science applications. The shortage of good information on the distribution of alien species and their spatial dynamics is largely attributable to the cost, effort and expertise ...
Saving a tropical ecosystem from a destructive ant-scale (Pheidole megacephala, Pulvinaria urbicola) mutualism with support from a diverse natural enemy assemblage
(Springer Science+Business Media Dordrecht, 2013)
Ants can disrupt the natural biological
control of serious hemipteran pests by interfering with natural enemies, resulting in a change in ecosystem functioning. We focus here on interference by a highly
invasive ant ...
Trait-mediated indirect interactions in a marine intertidal system as quantified by functional responses
(Wiley-Blackwell, 2013)
Studies of trait-mediated indirect interactions (TMIIs) typically focus on effects higher predators have on per capita
consumption by intermediate consumers of a third, basal prey resource. TMIIs are usually evidenced by ...
Wiregrass (Aristida beyrichiana) may limit woody plant encroachment in longleaf pine (Pinus palustris) ecosystems
(University of Notre Dame, 2017)
Wiregrass (Aristida beyrichiana) is a dominant groundcover species that facilitates
fire in southeastern U.S.A. pine savannas, thereby limiting woody plant cover and maintaining a herbaceous dominated understory. In ...
Advancing impact prediction and hypothesis testing in invasion ecology using a comparative functional response approach
(Springer, 2014-04)
Invasion ecology urgently requires predictive
methodologies that can forecast the ecological impacts of existing, emerging and potential invasive species. We argue that many ecologically damaging invaders are characterised ...
Small urban centres as launching sites for plant invasions in natural areas: insights from South Africa
(Springer, 2017)
Alien species are often first introduced to
urban areas, so it is unsurprising that towns and cities are often hotspots for invasions. However, while large cities are usually the first sites of introduction, small towns ...
A novel bioenergy feedstock in Latin America? Cultivation potential of Acrocomia aculeate under current and future climate conditions
(Elsevier Ltd, 2016)
Plant oil is a key commodity in the global economy, particularly for food and bioenergy markets. However, current production practices often impair smallholder livelihoods, cause land use changes, and
compete for food ...
Identifying barriers to effective management of widespread invasive alien trees: Prosopis species (mesquite) in South Africa as a case study.
(Elsevier Ltd, 2016)
Biological invasions are a major driver of ecological and social change globally. The negative effects of these invasions have led to the initiation of programs to manage these invasions across the world. Management aims ...
Distribution of the invasive alien weed, Lantana camara, and its ecological and livelihood impacts in eastern Africa
(NISC (Pty) Ltd, 2017)
Lantana camara (lantana) is a major invasive shrub globally, impacting upon biodiversity, economies, ecosystem services, and driving socio-ecological change. The aim of this study was to determine the current and potential ...
Species richness-environment relationships of European arthropods at two spatial grains: Habitats and countries
(2012)
We study how species richness of arthropods relates to theories concerning net primary productivity, ambient energy,
water-energy dynamics and spatial environmental heterogeneity. We use two datasets of arthropod richness ...
