Coexistence and Spread of Competitors in Heterogeneous Landscapes
Bulletin of Mathematical Biology, 2010Competition between species is ubiquitous in nature and therefore widely studied in ecology through experiment and theory. One of the central questions is under which conditions a (rare) invader can establish itself in a landscape dominated by a resident species at carrying capacity. Applying the same question with the roles of the invader and resident

Landscape heterogeneity—a quantitative criterion for landscape reconstruction
Landscape and Urban Planning, 2002Abstract The North Bohemian brown coal basin is located near to the frontier between the Czech Republic and Germany. It is a part of wider region known as the Black Triangle. Open-cast coal mining has caused total destruction of original ecosystems, as well as changes of relief and also land-use changes in the surrounding areas. Specialists call this

Functional landscape heterogeneity and animal biodiversity in agricultural landscapes
Ecology Letters, 2010Ecology Letters (2011) 14: 101–112AbstractBiodiversity in agricultural landscapes can be increased with conversion of some production lands into ‘more‐natural’– unmanaged or extensively managed – lands. However, it remains unknown to what extent biodiversity can be enhanced by altering landscape pattern without reducing agricultural production.

Infectious Disease Dynamics in Heterogeneous Landscapes
Annual Review of Ecology, Evolution, and Systematics, 2016Infectious diseases dynamics are affected by both spatial and temporal heterogeneity in their environments. Our ability to quantify and predict how this heterogeneity impacts risks of infection and disease emergence is the key to successful disease prevention efforts.

Heterogeneous landscapes promote population stability
Ecology Letters, 2010Ecology Letters(2010) 13: 473–484AbstractHabitat heterogeneity is often suggested as being important for the stability of populations, and promoted as a means to aid the conservation of species, but the evidence for such an assumption is poor. Here we show that heterogeneous landscapes that contain a variety of suitable habitat types are associated ...

Dispersal and Metapopulation Viability in a Heterogeneous Landscape
Journal of Theoretical Biology, 1999Conditions of persistence or extinction of a metapopulation of a colonizing annual species are studied in a heterogeneous landscape, a mixture of two elementary landscapes. An elementary landscape is a landscape whose age-structure is described by only one transition matrix, giving the probability for a site to be disturbed, or to follow the process of
