When astronomers meet ecologists: how remote sensing can tackle Parthenium in Pakistan

“Usually I’m looking up at the stars but with this project, I’m back down to earth” quips Dr Rene Breton, Director of Research at the School of Physics and Astronomy at the University of Manchester. By combining the skills of a geographer, ecologist, social scientist, entomologist, astrophysicist, biologist, and electrical engineer, the joint CABI and University of Manchester team aim to capitalise on the unique skills from each subject to tackle the highly invasive weed Parthenium in Pakistan using remote sensing.

Invasive alien species should not be used in restoring degraded landscapes as their costs outweigh their benefits, experts say.

Invasive alien species, according to the Convention on Biological Diversity, are plants, animals and other organisms that are non-native to an ecosystem, and may adversely affect human health and the environment, including decline or elimination of native species.

Red swamp crayfish (Procambarus clarkii), often known as the Louisiana crawfish are staple part of Cajun cuisine. However, new research published in Conservation Biology has found that the highly invasive crayfish allows mosquitoes to thrive in waterways, therefore making it more likely to increase the risk of mosquito-borne diseases.  Continue reading

Tiny mite could prove a ‘mighty’ weapon in the fight against one of the UK’s most invasive weeds

CABI scientists are stepping up the fight against one of the UK’s most invasive non-native aquatic weeds.

Crassula is an aquatic plant that can take on various growth forms; able to act as a submerged, emergent, or semi-terrestrial species.

Approval has been given for the release of a novel biological control agent – the mite, Aculuscrassulae – to assess its ability in the real-world environment to suppress Australian swamp stonecrop (Crassula helmsii), also known as New Zealand pigmyweed. This follows carefully controlled laboratory testing to ensure the safe, controlled release of the mite in the UK.

Invasive Species Are Riding on Plastic Across the Oceans

We know plastics are as plentiful in parts of the open ocean as they are in our everyday lives. But, until recently, scientists didn’t consider that such debris could also be carrying a new wave of invasive species to the shores of the United States. Now they’re finding that not only is that happening, but they suspect that some of the species will thrive.
