To predict the spread of invasive species, we need to understand the mechanisms that
underlie their range expansion. Assuming random diffusion through homogeneous …

During a biological invasion, we expect that the expanding front will increasingly become
dominated by individuals with better dispersal abilities. Over many generations, selection at …

Invasive species threaten biological diversity throughout the world. Understanding the
dynamics of their spread is critical to mitigating this threat. In Australia, efforts are underway …

An ability to predict the rate at which an organism spreads its range is of growing importance
because the process of spread (during invasion by an exotic species) is almost identical to …

Human activities are changing habitats and climates and causing species' ranges to shift.
Range expansion brings into play a set of powerful evolutionary forces at the expanding …

In biological invasions, rates of range expansion tend to accelerate through time. What kind
of benefits to more rapidly dispersing organisms might impose natural selection for faster …

Populations on the edge of an expanding range are subject to unique evolutionary
pressures acting on their life‐history and dispersal traits. Empirical evidence and theory …

Dispersal biology at an invasion front differs from that of populations within the range core,
because novel evolutionary and ecological processes come into play in the nonequilibrium …

Invasions often accelerate through time, as dispersal-enhancing traits accumulate at the
expanding range edge. How does the dispersal behaviour of individual organisms shift to …

Cane toads (Bufo marinus) are now moving about 5 times faster through tropical Australia
than they did a half-century ago, during the early phases of toad invasion. Radio-tracking …
