Invasion by land, river, and sea
One obvious effect of climate change will be the spread of invasive species and the subsequent ecological, commercial, and health repercussions. Therefore, studies that address the patterns of colonization and possible underlying genetic mechanisms that may lend to being a … Continue reading
Artificial connectivity … have we overlooked the native range?
Invasive species are problematic throughout the world’s ecosystems, down even to their very name which incites heated debates. Every month, studies are published that describe the genetic structure and gene flow of non-native species in their introduced ranges. Often, these … Continue reading

Signatures of the reproductive lottery
In marine populations, effective population sizes are usually several orders of magnitude lower than the census size. This difference is thought to be driven by high fecundity, variation in reproductive success and pronounced early mortality, resulting in genetic drift across generations. In … Continue reading
