Can invasive plants become new species in their invaded range?

Ramona Irimia and Daniel Montesinos discuss their recent Journal of Ecology article: “Experimental admixture among geographically disjunct populations of an invasive plant yields a global mosaic of reproductive incompatibility and heterosis”. Find out more about their insights into the biogeographic patterns of variation in reproductive success in the yellow star-thistle, an invasive weed. Invasive plants…

What is the effect of gene flow origin on the adaptive potential of environmentally marginal populations?

Journal of Ecology has just published a new research article by Morente-López et al. ‘Gene flow effects on populations inhabiting marginal areas: origin matters’. Lead author Javier Morente-López discusses the paper and its implications.  Climate change is causing species to experience new environmental pressures, leading to changes in their distributions and affecting ecological niches. It…
