Invasion and eradication of a competitively superior species in heterogeneous landscapes

Alexandre Buttler, Séverine Vuilleumier Varisco

The effect of heterogeneous environments upon the dynamics of invasion and the eradication or control of invasive species is poorly understood, although it is a major challenge for biodiversity conservation. Here, we first investigate how the probability a ...

Potential impacts of precipitation change on large-scale patterns of tree diversity

Andrea Rinaldo, Enrico Bertuzzo

Forests are globally important ecosystems host to outstanding biological diversity. Widespread efforts have addressed the impacts of climate change on biodiversity in these ecosystems. We show that a metacommunity model founded on basic ecological processe ...

A rapid response of testate amoebae and vegetation to inundation of a kettle hole mire

Our palaeoecological study covers 73 years of history (1929-2002) of a kettle hole peatland inundated by water from a nearby, dammed lake. Testate amoebae, pollen and non-pollen palynomorphs (NPPs) were used to track the shift to wetter conditions in the p ...

Relative Extinction of Heterogeneous Agents

Semyon Malamud

In all the existing literature on survival in heterogeneous economies, the rate at which an agent vanishes in the long run relative to another agent can be characterized by the diﬀerence of the so-called survival indices, where each survival index only dep ...

The fixation of locally beneficial alleles in a metapopulation

Séverine Vuilleumier Varisco

Extinction, recolonization and local adaption are common in natural spatially structured populations. Understanding their effect upon genetic variation is important for systems such as GMO management, or avoidance of drug resistance. Theoretical studies on ...
