Animal species diversity driven by habitat heterogeneity/diversity: the importance of keystone structures
Aim  In a selected literature survey we reviewed studies on the habitat heterogeneity–animal species diversity relationship and evaluated whether there are uncertainties and biases in its empiricalExpand
Human-mediated dispersal of seeds over long distances
Human activities have fundamental impacts on the distribution of species through altered land use, but also directly by dispersal of propagules. Rare long-distance dispersal events have aExpand
Historical distribution and regional dynamics of two Brassica species
Plants often show a patchy distribution. This can be related to the discontinuous distribution of environmental variables that define suitable habitat. Metapopulation theory suggests that additionalExpand
Human-Mediated Dispersal of Seeds by the Airflow of Vehicles
Human-mediated dispersal is known as an important driver of long-distance dispersal for plants but underlying mechanisms have rarely been assessed. Road corridors function as routes of secondaryExpand
Extinction risk in periodically fluctuating environments
Abstract Periodically fluctuating environments occur in various ways in nature but have not, however, been studied in detail yet in the context of the color of environmental noise and extinction riskExpand
Extinction risk, coloured noise and the scaling of variance.
The impact of temporally correlated fluctuating environments (coloured noise) on the extinction risk of populations has become a main focus in theoretical population ecology. In this study weExpand
Implication of climate change for the persistence of raptors in arid savanna
Arid savannas are regarded as one of the ecosystems most likely to be affected by climate change. In these dry conditions, even top predators like raptors are affected by water availability andExpand
Process-based functions for seed retention on animals: a test of improved descriptions of dispersal using multiple data sets
Studies of external seed transport on animals usually assume that the probability of detachment is constant, so that seed retention should show a simple exponential relationship with time. ThisExpand
