Invasions by alien plants provide a unique opportunity to examine competitive interactions
among plants. While resource competition has long been regarded as a major mechanism …

Invasive nonindigenous plant species (NIPS) threaten native diversity, alter ecosystem
processes, and may interact with other components of global environmental change. Here, a …

▪ Abstract Quantifying the extent to which seed production is limited by the availability of
pollen has been an area of intensive empirical study over the past few decades. Whereas …

Introduced plant populations lose interactions with enemies, mutualists and competitors from
their native ranges, and gain interactions with new species, under new abiotic conditions …

Invasive alien species affect the composition and functioning of invaded ecosystems in
many ways, altering ecological interactions that have arisen over evolutionary timescales …

Global change may substantially affect biodiversity and ecosystem functioning but little is
known about its effects on essential biotic interactions. Since different environmental drivers …

As global surface temperatures rise, global precipitation rates are predicted to increase.
These localised increases in rainfall patterns may significantly affect plant–pollinator …

1 Multiple-species floral displays have been hypothesized to facilitate pollination by
attracting a greater number and/or diversity of pollinators. Here I present experimental …

Interspecific pollen transfer (IPT) is one of the mechanisms underlying potential competition
among plants for pollinators, and it refers to movement of pollen between different plant …

Pollination commonly limits seed production, as addition of pollen to stigmas often increases
fecundity. This response is usually interpreted as evidence that plants' stigmas receive too …
