Evolution and the latitudinal diversity gradient: speciation, extinction and biogeography.
Two major hypotheses for the origin of the latitudinal diversity gradient are reviewed, including the time and area hypothesis and the diversification rate hypothesis, which hold that tropical regions diversify faster due to higher rates of speciation, or due to lower extinction rates. Expand
The invasion paradox: reconciling pattern and process in species invasions.
It is concluded that natively rich ecosystems are likely to be hotspots for exotic species, but that reduction of local species richness can further accelerate the invasion of these and other vulnerable habitats. Expand
Ecological and evolutionary insights from species invasions.
How the study of invasions can help to inform the understanding of applied problems, such as extinction, ecosystem function and the response of species to climate change is emphasized. Expand
Species Invasions Exceed Extinctions on Islands Worldwide: A Comparative Study of Plants and Birds
The results suggest that species richness may be increasing at subglobal scales for many groups and that future research should address what consequences this may have on ecological processes. Expand
Species diversity: from global decreases to local increases
Current patterns of global change can strongly affect biodiversity at global, regional and local scales. At global scales, habitat destruction and the introduction of exotic species are contributingExpand
The potential conservation value of non-native species.
The proportion of non-native species that are viewed as benign or even desirable will slowly increase over time as their potential contributions to society and to achieving conservation objectives become well recognized and realized. Expand
Balancing biodiversity in a changing environment: extinction debt, immigration credit and species turnover.
A conceptual framework for biodiversity dynamics following environmental change is outlined that incorporates lags in extinction and immigration, which lead to extinction debt and immigration credit, respectively, which enable a balanced consideration of changes in biodiversity following climate change, habitat fragmentation and other forcing events. Expand
Evidence for the role of infectious disease in species extinction and endangerment.
Although infectious diseases appear to play a minor role in global species loss, the findings underscore two important limitations in the available evidence: uncertainty surrounding the threats to species survival and a temporal bias in the data. Expand
The paradox of invasion
It is paradoxical that exotic species invade and displace native species that are well adapted to local environments. Yet, even those exotics that eventually become abundant and widespread, often doExpand
Species Invasions: Insights into Ecology, Evolution, and Biogeography
This book discusses Species Invasions as the "Rosetta Stone" of Ecology, as well as insights into the Mechanisms that Drive Evolutionary Change, and potential tests of Theories of Niche Conservatism and Evolution. Expand
