Species invasions are extremely common and are vastly outpacing the ability of resource agencies to address each invasion, one species at a time. Management actions that target the whole landscape or ecosystem may provide more cost‐effective protection against the establishment of invasive species than a species‐by‐species approach. To explore what ecosystem‐level actions might effectively reduce invasions, we developed a multispecies, multihabitat metapopulation model. We assume that species… 

Habitat Fragmentation Increases Overall Richness, but Not of Habitat-Dependent Species

Debate rages as to whether habitat fragmentation leads to the decline of biodiversity once habitat loss is accounted for. Previous studies have defined fragmentation variously, but research needs to

The Implementation of Habitat Destruction Methods That Promote Native Survival Under Invasion

Controlling invasive alien species invasion and maintaining the survival of native species have attracted increasing attention, and habitat destruction can be used to achieve these aims. However,

Coexistence of Specialist and Generalist Species Is Shaped by Dispersal and Environmental Factors

This work addressed the question of the coexistence of specialist and generalist species with a spatially explicit metacommunity model in continuous and heterogeneous environments by characterized how species’ dispersal abilities, the number of interacting species, environmental spatial autocorrelation, and disturbance impact community composition.

Coexistence of Habitat Specialists and Generalists in Metapopulation Models of Multiple-Habitat Landscapes

This work presents a simple, but previously unrecognized, mechanism for coexistence of a habitat generalist and a number of habitat specialist species and shows that coexistence is easily possible.

Forest Loss and the Biodiversity Threshold: An Evaluation Considering Species Habitat Requirements and the Use of Matrix Habitats

The results highlight the potential for biodiversity thresholds in human-modified landscapes, and the importance of landscape heterogeneity to biodiversity, and highlight that cross habitat spillover may be asymmetrical and contingent on landscape context, occurring mainly from forests to the matrix and only in more forested landscapes.

Invasion, Disturbance, and Competition: Modeling the Fate of Coastal Plant Populations

These models contribute new insight into the relationship between environmental disturbance and invasion and demonstrate how influential abiotic factors such as climate change will be in determining interspecific interactions.

Climate and habitat configuration limit range expansion and patterns of dispersal in a non‐native lizard

Abstract Invasive species are one of the main causes of biodiversity loss worldwide. As introduced, populations increase in abundance and geographical range, so does the potential for negative

Specialist species of wood‐inhabiting fungi struggle while generalists thrive in fragmented boreal forests

It is shown that the expected number of red-listed species per a fixed amount of similar resources (dead trees) can be even more than 10 times higher in well-connected than in fragmented surroundings, and thus, protecting high-quality areas that are well connected is conservationally more effective than protecting small fragments distributed across the landscape.



Dynamics of metapopulations : habitat destruction and competitive coexistence

The present study suggests that patch removal can by itself favour 'weedy' species, even in the absence of other, concomitant changes.

Habitat destruction and the extinction debt

A model is described that explains multispecies coexistence in patchy habitats and which predicts that their abundance may be fleeting, a future ecological cost of current habitat destruction.

Ecological Attributes of Extinction‐Prone Species: Loss of Freshwater Fishes of Virginia

I examined patterns of extirpation among Virginia’s 197 historically native freshwater fish species to address the following questions: (1) Are extinction-prone species ecologically distinct? and (2)

Extinction Vulnerability and Selectivity: Combining Ecological and Paleontological Views

This work has shown that replacement of vulnerable taxa by rapidly spreading taxa that thrive in human-altered environments will ultimately produce a spatially more homogenized biosphere with much lower net diversity.

Competition and Habitat Selection: Test of a Theory Using Small Mammals

Two hypotheses about community structure were examined for the small mammals occupying a wet grassland in SW North Dakota, USA and no competitive effects were observed among Microtus, Zapus and Spermophilus.

Invasiveness and comparative life-history traits of exotic and indigenous Senecio species in Australia

It is suggested that invasiveness is essentially unpredictable, due to habitat/plant specific interactions between invader and area of introduction and quarantine authorities should use a combination of methods to assess invasive potential.

Competition and the structure of bird communities.

Professor Cody's monograph emphasizes the role of competition at levels above single species populations, and describes how competition, by way of the niche concept, determines the structure of

Can life‐history traits predict the fate of introduced species? A case study on two cyprinid fish in southern France

A field study seems to suggest that invasive vigour also results from the ability to tolerate environmental changes through phenotypic plasticity, rather than from particular life-history features pre-adapted to invasion.


Biologists are nearly unanimous in their belief that humanity is in the process of extirpating a significant portion of the earth's spe­ cies. The ways in which we are doing so reflect the magnitude
