Invasive weeds in America’s Western states: restoring balance using biological control

In many of America’s Western states, invasive weeds such as houndstongue (Cynoglossum officinale), Russian knapweed (Rhaponticum repens), yellow and Dalmatian toadflax (Linaria vulgaris and Linaria dalmatica), oxeye daisy (Leucanthemum vulgare), and hoary cress (Lepidium draba) are serious problems. However, research shows that biological control, as part of an integrated weed management strategy, offers the potential for a cost effective and efficient way of reducing invasive plant species to levels below acceptable damage thresholds.

New research assesses the effect of invasive crayfish on mosquito survival

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.

Invasive Species Are Riding on Plastic Across the Oceans

Reblogged from National Geographic 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…

Using DNA to detect a stinkbug invasion

The use of DNA to detect a stinkbug invasion proposes a revolutionary advancement in agricultural pest surveillance following the success recorded on a piloted experiment conducted on farms in the USA. These interlopers attack all manner of produce, ranging from fruits to leafy vegetables.  However, the adoption of DNA techniques in detecting its early invasion…
