Satellite-based monitoring of primary production in a mediterranean islet post black rat eradication
Invasive rodents have a detrimental impact on terrestrial ecosystem functioning, this is often exacerbated on small islands. Rat eradication campaigns are often used to deal with this environmental perturbation given their classification as invasive species. Studies assessing the effects of rodent c...

Invasive rodents have a detrimental impact on terrestrial ecosystem functioning, this is often exacerbated on small islands.
