Genetic Consequences of Range Expansions
Annual Review of Ecology, Evolution, and Systematics, 2009Although range expansions have occurred recurrently in the history of most species, their genetic consequences have been little investigated. Theoretical studies show that range expansions are quite different from pure demographic expansions and that the extent of recent gene flow conditions expected patterns of molecular diversity within and between ...

Eco-evolutionary dynamics of range expansion
Ecology, 2020 AbstractUnderstanding the movement of species’ ranges is a classic ecological problem that takes on urgency in this era of global change. Historically treated as a purely ecological process, range expansion is now understood to involve eco‐evolutionary feedbacks due to spatial genetic structure that emerges as populations spread.

Interspecific competition slows range expansion and shapes range boundaries [PDF]
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Range expansion is how invasive species spread and how species track habitats shifting from climate change, so understanding this process is a key applied and basic challenge. Ecologists have long theorized that a competitor can slow or even halt range expansion. However, there has never been definitive empirical evidence

Population genetics and range expansions
Physics Today, 2009On a molecular level and at the frontiers of expanding habitats, large stochastic fluctuations can obscure signals of Darwinian evolution.

The loss of self‐incompatibility in a range expansion
Journal of Evolutionary Biology, 2020Abstract It is commonly observed that plant species' range margins are enriched for increased selfing rates and, in otherwise self‐incompatible species, for self‐compatibility (SC). This has often been attributed to a response to selection under mate and/or pollinator limitation.

Host range expansion is density dependent
Oecologia, 2016The realized host range of herbivores is expected to increase with herbivore population density. Theory also predicts that trait similarity and phylogenetic relatedness between native and exotic plants is expected to increase the susceptibility of introduced plants to feeding by native herbivores.

AbstractThis chapter explores the spatial dynamics of invading species, paying particular attention to the patterns formed as they spread, i.e., the rate of increase of the area invaded and the rate at which their boundaries move. The development of models for population expansion — comprising a range of structures and assumptions both simple and ...

Physiological flexibility in an avian range expansion
General and Comparative Endocrinology, 2014The mechanisms that enable animals to colonize new areas are little known, but growing evidence indicates that the regulation of stress hormones is important. Stress hormones probably influence invasions because they enable organisms to adjust their phenotypes depending on environmental context.
