Soil sterilization and fertility impacts on urease and belowground mass specific phosphatase activity vary among Chinese tallow tree (Triadica sebifera) populations
Invasive plants from introduced populations may utilize soil nutrients more efficiently and increase their performance relative to those from native...

A meta-analysis of the evolution of increased competitive ability hypothesis: genetic-based trait variation and herbivory resistance trade-offs
Non-native organisms are an abundant component of almost all global ecosystems. A prominent framework to explain the success of non-native plants is...

Away-range shifts in leaf function of a global invader: a case of resource reallocation?
Leaf resource allocation plays a significant role in the evolution of plant functional strategies, where tradeoffs between defense, structure, and...

Evidence for evolution of increased competitive ability for invasive Centaurea solstitialis, but not for naturalized C. calcitrapa
Congeneric species with the same native and non-native ranges, but exhibiting different invasiveness, provide opportunities to assess the relative...

Variation in defensive traits against herbivores of native and invasive populations of Carpobrotus edulis
The Enemy Release Hypothesis (ERH) predicts that the escape from natural enemies, such as specialist herbivores, may explain the invasiveness of some...
-
Invaders responded more positively to soil biota than native or noninvasive introduced species, consistent with enemy escape
Understanding the mechanisms governing biological invasions has implications for population dynamics, biodiversity, and community assembly. The enemy...

Biogeographic variation in resistance of the invasive plant, Alliaria petiolata, to a powdery mildew fungus and effect of resistance on competitive dynamics
Garlic mustard is an invasive Eurasian biennial that has spread throughout the eastern United States and southern Canada. Populations of this plant...

Effects of above- and belowground herbivory of specialists and generalists on the growth and defensive chemicals of introduced and native Chinese tallow seedlings
Background and aimsSpatially separated aboveground (AG) and belowground (BG) herbivores can affect each other and alter plant growth and defense,...
-
Introduced populations of the garden lupine are adapted to local generalist snails but have lost alkaloid diversity
Intraspecific variation in growth and defence among plant populations can be driven by differences in (a)biotic conditions, such as herbivory and...
-
High photosynthetic capacity and energy-use efficiency benefit both growth and chemical defense in invasive plants
In nature some successful invasive plants grow faster and are better chemical defenders than native plants, which appears to contradict the...

Regional differences in clonal Japanese knotweed revealed by chemometrics-linked attenuated total reflection Fourier-transform infrared spectroscopy
BackgroundJapanese knotweed ( R. japonica var japonica) is one of the world’s 100 worst invasive species, causing crop losses, damage to...

Biotic Interactions as Mediators of Biological Invasions: Insights from South Africa
Ecological interactions, especially those that are beneficial (i.e. mutualism) or detrimental (i.e. parasitism), play important roles during the...

Ecological realism and rigor in the study of plant-plant allelopathic interactions
Progress in understanding allelopathic interactions among plants has long been hampered by the complexity of the many direct and indirect...
-
Release from below- and aboveground natural enemies contributes to invasion success of a temperate invader
AimsEfforts to concurrently test for enemy release of both above- and belowground enemies for invasive plants in non-native range are limited....

Predation and avoidance behavior of the pea aphid Acyrthosiphon pisum confronted with native and invasive lady beetles in Europe
Invasive species are a major driver of global biodiversity loss. However, we often lack a mechanistic understanding why some non-native species...
-
The invasion triangle in the range dynamics of invasive species following successful establishment
A wide range of factors drive the processes responsible for range dynamics following a successful invasion. These drive changes to the demographic...

Innate immunity of Florida cane toads: how dispersal has affected physiological responses to LPS
Physiological tradeoffs occur in organisms co** with their environments, which are likely to increase as populations reach peripheries of...
-
Evolution of increased Medicaco polymorpha size during invasion does not result in increased competitive ability
Species invading new habitats experience novel selection pressures that can lead to rapid evolution, which may contribute to invasion success and/or...
