Allelopathy (ie, chemical interaction among species) was originally conceived as inclusive of
positive and negative effects of plants on other plants, and we adopt this view. Most studies …

Evidence is mounting that the immense diversity of microorganisms and animals that live
belowground contributes significantly to sha** aboveground biodiversity and the …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Plants can produce and release allelochemicals to interfere with the establishment and
growth of conspecific and interspecific plants. Such allelopathy is an important mediator …

Plant–soil feedbacks is becoming an important concept for explaining vegetation dynamics,
the invasiveness of introduced exotic species in new habitats and how terrestrial …

Biological invasions are 'natural'experiments that can improve our understanding of
contemporary evolution. We evaluate evidence for population differentiation, natural …

Plant diversity and biogeochemical cycles are rapidly changing in response to exotic plant
species invasion. However, there are conflicting conclusions regarding the quantification of …

During the last centuries, humans have transformed global ecosystems. With their temporal
dimension, herbaria provide the otherwise scarce long‐term data crucial for tracking …

The influence of genetic variation on invasion success has captivated researchers since the
start of the field of invasion genetics 50 years ago. We review the history of work on this …

Mean surface temperatures have increased globally by~ 0.7 C per century since 1900 and
0.16 C per decade since 1970 (Levinson and Fettig 2014). Most of this warming is believed …
