Biological invasions into wholly new regions are a consequence of a far reaching but underappreciated component of global environmental change, the human-caused breakdown of biogeographic barriers to species dispersal . Human activity moves species from place to place both accidentally and deliberately-and it does so at rates that are without precedent in the last tens of millions of years. As a result , taxa that evolved in isolation from each other are being forced into contact in an instant…

Importance of Species Replication in Understanding Plant Invasions into North American Grasslands

This chapter found that areas in Saskatchewan, Canada, dominated by the introduced forage grass Agropyron cristatum are sequestering less C into their soils compared to developing native prairie stands with similar land use histories.

A paleoecologic perspective on past plant invasions in Yellowstone.

Future conditions are likely to create evermore opportunities for exotic species to invade and establish within the Yellowstone region, and regional climate and biotic changes in response to projected increases in atmospheric CO2 in the next century suggest an even more complex picture than in the past.

African Grass Invasion in the Americas: Ecosystem Consequences and the Role of Ecophysiology

The extent of pasture creation with African grasses and their invasive spread in the New World is described and a number of comparative ecophysiological studies within the context of mechanisms responsible for invasion by African Grasses and resulting ecosystem change are highlighted.

Do Plant Invasions Change the Effects of Fire on Animals?

This paper develops a framework to evaluate whether fire and plant invasion act as independent, additive processes, or whether applying fire in invaded areas results in novel effects on wildlife.

Biological invasions and climate change amplify each other’s effects on dryland degradation

Drought under warmed conditions exceeded the tolerance limits of the native species, resulting in greater and more rapid mortality than the exhibited by the invasive, which can be expected to synergistically accelerate ecosystem degradation unless large-scale interventions are enacted.

In the long-term, the “weedy” taxa that became the dominants of the novel conditions imposed by global change should become the progenitors of a series of new species that are progressively less weedy and better adapted to the new conditions.

Linking Plant Invasions to Global Environmental Change

Biotic invasions have been recognized as an important element of global change (Vitousek 1994). Introductions of alien species into novel habitats have increased in tandem with travel and

Can biological invasions induce desertification?

A new desertification paradigm is presented that includes the invasion of stable desert shrublands by exotic annual grasses and suggests that two major drivers of global environmental change, namely biological invasions and climate change, may act in concert and amplify each other’s effect on land cover and soil resources.

Ecophysiological Aspects of the Invasion by African Grasses and Their Impact on Biodiversity and Function of Neotropical Savannas

In neotropical savannas, inadvertent or deliberate introduction of African grasses since colonial times was followed by spontaneous spread of the invaders and more recent introductions in this century have spread out rapidly and partially displaced native grasses.

The research of Lavergne and Molofsky reported in this issue of PNAS examines the factors that contribute to range expansion and the invasiveness of Phalaris arundinacea L. (reed canarygrass) in North America and provides powerful insights into the role of evolution in the invasion process.



Alien Grass Invasion and Fire In the Seasonal Submontane Zone of Hawai'i

Grass invasion could initiate a grass/fire cycle whereby invading grasses promote fire, which in turn favors alien grasses over native species, in Hawai'i.

Global Change: Effects on Forest Ecosystems and Wildfire Severity

Climate change, as a result of the greenhouse effect, is expected to take place within the next 100 years — a time span comparable to the planting-to-harvest interval of many commercial tree species.

Management of Habitat Fragments in a Tropical Dry Forest: Growth

The biology of habitat initiation and growth in a Costa Rican tropical dry forest is examined and it is found that vertebrate-generated forests contain more food items of interest to animals, are more species rich, and are more evergreen than are wind- generated forests.

Effects of Alien Plant Invasions on Native Vegetation Remnants on La Réunion (Mascarene Islands, Indian Ocean)

Although most of the lowland endemic forests of the mountainous Indian Ocean island of La Réunion have been converted by Man to other land-uses, relatively intact ecosystems still survive at higher

Comparative demography of co-occurring introduced and native tussock grasses: persistence and potential expansion

Demographic factors associated with seeds of A. desertorum seemed to favor the maintenance and spread of this introduced grass into native stands formerly dominated by A. spicatum, and individuals of both species emerging after April were unable to survive the summer drought.

Biological invasion by Myrica faya in Hawai'i: plant demography, nitrogen fixation, ecosystem effects

It is concluded that biological invasion by Myrica faya alters ecosystem-level properties in this young volcanic area; at least in this case, the demography and physiology of one species controls characteristics of a whole ecosystem.

Extinction of an Island Forest Avifauna by an Introduced Snake

The island of Guam has experienced a precipitous decline of its native forest birds, and several lines of evidence implicate the introduced brown tree snake (Boiga irregularis) as the cause of the
