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 …

G. Evelyn Hutchinson more than a half century ago proposed that one could characterize the
ecological niche of a species as an abstract mapping of population dynamics onto an …

Marine provinces, founded on contrasting floras or faunas, have been recognized for more
than 150 years but were not consistently defined by endemism until 1974. At that time …

Detailed knowledge about the geographical pathways followed by propagules from their

Aim Shifts in species ranges are a predicted and realized effect of global climate change;
however, few studies have addressed the rates and consequence of such shifts, particularly …

Abstract Despite a growing awareness that the herbaceous layer serves a special role in
maintaining the structure and function of forests, this stratum remains an underappreciated …

Predation by exotic species has caused the extinction of many native animal species on

Species invasions provide numerous unplanned and frequently, but imperfectly, replicated
experiments that can be used to better understand the natural world. Classic studies by …

Despite the increasing biological and economic impacts of invasive species, little is known
about the evolutionary mechanisms that favor geographic range expansion and evolution of …

The publication, in 1958, of Charles Elton's book The ecology of invasions by animals and
