In 1916, the US began releasing Asian lady beetles to control aphids and scale insects; decades later Harmonia axyridis became invasive and was linked to declines of native ladybirds
The multicoloured Asian lady beetle was introduced to the United States with a clear purpose. Starting…
Scientists develop DNA markers to detect Burmese pythons in southern Florida waters, but finding the snakes remains difficult |
Scientists have developed and optimised python-specific environmental DNA (eDNA) markers to detect Burmese pythons through water…
In 1910, Oregon planted European beachgrass to stabilize shifting dunes; it spread along the coast, reshaped the landscape and squeezed open sandy habitat used by native wildlife
European beachgrass (Ammophila arenaria) is now well established in the Oregon dunes In 1910, Oregon introduced…
Michigan scientists covered invasive zebra mussels with weighted lakebed mats and pumped carbon dioxide underneath; after five days, mortality of caged mussels topped 80%
The approach is based partly on earlier laboratory research suggesting that carbon dioxide can be more…
In 1869, 100 sheep were introduced to Mexico’s Socorro Island; the herd grew to about 5,000 and damaged 30% of the island, then removing 1,762 helped forest cover rise from 29% to 85%

Invasive blue crabs cost Italy’s shellfish industry tens of millions of euros; scientists release 130,000 octopuses into Adriatic Sea to keep them in check
Scientists release 130,000 young octopuses into Italy’s Adriatic Sea to help control invasive blue crabs. Italy…
In the 1970s, Britain imported North American signal crayfish for farms; they escaped, bred in huge numbers and now infest rivers across England, Wales and Scotland, carrying a plague deadly to native crayfish
In the 1970s, British aquaculture businesses imported North American signal crayfish to stock farms, hoping to…
