Ecological impacts of invasive alien species along temperature gradients: testing the role of environmental matching
(Ecological Society of America, 2015)
Invasive alien species (IAS) can cause substantive ecological impacts, and the role of temperature in mediating these impacts may become increasingly significant in a
changing climate. Habitat conditions and physiological ...
Population density modifies the ecological impacts of invasive species
(Nordic Society Oikos, 2015)
In assessments of ecological impact in invasion ecology, most studies compare un-invaded sites with highly invaded sites,
representing the ‘worst-case scenario’, and so there is little information on how impact is modified ...
Reproductive ecology and diet of a persistent Ameiurus melas (Rafinesque, 1820) population in the UK
(Blackwell Verlag GmbH, 2015)
The black bullhead Ameiurus melas was introduced to Europe from North America in the early 20th Century and invasive populations are now present in many European
countries (Novomeska et al., 2013). Their invasion is ...
Interactions among multiple invasive animals
(Ecological Society of America, 2015)
With accelerating rates of invasion being documented in many ecosystems, communities of interacting invasive species are becoming increasingly common. Opposing theories predict that invaders can either hinder or promote ...
Predation in the marine intertidal amphipod Echinogammarus marinus Leach: Implications of inter- and intra-individual variation
(Elsevier, 2015)
Studies of competition, predator–prey dynamics and foodwebs typically consider conspecifics as equal, however, individuals from the same population that are seemingly identical can show considerable variation with regards ...
Climate change expected to drive habitat loss for two key herbivore species in an alpine environment
(John Wiley & Sons Ltd, 2015)
Aim Our first aim was to determine the environmental factors associated with two native Australian Lepidoptera species, Lomera caespitosae and Oncopera alpina, key herbivores of alpine and subalpine Poa grasses. Both species ...
Ecological impacts of alien species: Quantification, scope, caveats, and recommendations
(Oxford University Press, 2015)
Despite intensive research during the past decade on the effects of alien species, invasion science still lacks the capacity to accurately predict the impacts of those species and, therefore, to provide timely advice to ...
No differences in genetic diversity of Cotoneaster franchetii (Rosaceae) shrubs between native and non-native ranges
(Sociedad Argentica de Botanica, 2015)
It is commonly assumed that plants have more genetic diversity in their native range than in areas where they have been introduced due to founder effects. However, few studies have proven this assumption and included the ...
Angling baits and invasive crayfish as important trophic subsidies for a large cyprinid fish
(Springer, 2015)
Invasive species and anthropogenic sources of
allochthonous trophic subsidies can have substantial ecological consequences for freshwater ecosystems, including modifying the diet of consumers and altering food web
structure. ...
Forecasting invasions: resource use by mussels informs invasion patterns along the South African coast
(Springer, 2015)
Invasive species are often more able to rapidly and efficiently utilise resources than natives, and comparing per capita resource use at different resource densities
among invaders and trophically analogous natives could ...
