Preventing Extinctions: Architecting an Accretocene - May 1

Jointly managed by the U.S. Fish and Wildlife Service and the Nature Conservancy, the atoll is a unique collection of natural reefs and engineered islets and lagoons. It may look like a postcard paradise, but 10 years ago Palmyra was in ecological freefall, with bird populations and native forest diminished - all because of the human introduction of rats nearly a century ago.
'Murder hornets' have arrived in the U.S.—here's what you should know - May. 4

The world's largest wasp has been spotted in Washington State, but don't panic—efforts are underway to stop it from spreading.
Reducing the spread of invasive pests by sea containers: a new IPPC factsheet available in all UN languages - May. 5

Keeping containers and cargos clean can seriously reduce the spread of invasive plant pests and diseases worldwide.
North Bay beekeeper not worried about Asian giant hornets - May. 10

ONTARIO - Last year, Asian giant hornets were found in British Colombia and Washington State. What makes these insects so dangerous is the amount of damage the hornets can inflict in a short while. “A colony of [Asian giant] hornets can kill up to 30,000 bees in a few hours," said Sparks.
A Q U A T I C
Brazil policy invites marine invasive species - Apr. 30

The plan is contraversial given that natural reefs and wrecks in Brazil are not overused by divers, and SCUBA is an expensive sport available to few people.
Salmon groups push ahead with fish kill in face of COVID-19 emergency
- May. 1

The bass - which are not native anywhere in Atlantic Canada - have escaped into the Miramichi River, where it is feared they could devastate native Atlantic salmon stocks by eating their young.
Ocean wastelands - May. 4

I started studying barrens, reading the work of experts on the issue from different angles (overfishing, invasive species, climate change, etc.). These people inspired my research from the beginning and now, we are joining efforts to deepen our understanding of the problem.
'Thousands of goldfish:' Concerns raised after goldfish dumped in Port Perry pond - May. 7

ONTARIO - The Scugog Lake Stewards are reminding residents that tiny goldfish could create big problems in the lake if disposed of improperly.
Invasive Comb Jellies Might Overproduce Babies in Summer to Eat Them in Winter - May. 11

They’re native to the western Atlantic but have expanded their range into other waters where they’re wreaking havoc on the food chain. Now, researchers have a new and brutal suggestion as to how comb jellies are so successful.

Cabin built using trees damaged by emerald ash borer - May. 6

Using custom-cut lumber from ash trees damaged by the emerald ash borer, assistant professors of architecture Leslie Lok and Sasa Zivkovic designed and fabricated a cabin from wood that otherwise would have been left to rot.
Some landscapes show resistance to ash dieback - May. 8

A study suggests that some types of environment help block the spread of ash dieback disease, which threatens millions of ash trees in the UK.
Lab successfully grows spotted lanternfly, opening door to new research - May. 11

PENNSYLVANIA - For years, researchers trying to learn more about the invasive spotted lanternfly and ways to kill it were limited by how hard it is to keep the invasive insects alive in captivity.
Deadly imports: In one U.S. forest, 25% of tree loss caused by foreign pests and disease - May. 12

Scientists have documented at least 450 foreign insects and pathogens that have found their way to North America and feed on trees.

Reseeding Great Salt Lake’s Wetlands After Phragmites
- May. 5

UTAH - The Great Salt Lake provides approximately 75% of Utah’s wetlands, and is a resting area along the Pacific- Americas flyway. Migratory birds rely on the lake as a stopping spot for rest and nutrition which they obtain from the variety of native plant communities.
Invasive shrub has no effect on prey abundance or physiological condition of migratory songbird - May. 5

A new study published this week in the journal  Conservation Physiology  shows that the relationships between exotic, invasive plants and native birds are not always that simple, and not always negative.
Study Shows Elevation Affects Fly’s Use as Natural Enemy of Invasive Weed - May. 7

Gall-inducing insects can be valuable natural enemies—especially in tackling invasive weeds—due to their narrow host range and low impact to non-target species. A new study reveals, however, that gall size and abundance can be dependent on elevation, which has important implications for the effectiveness of gall-inducing insects as biocontrol agents.
Satellite technology to help tackle invasive aquatic weeds - May 13

Scientists will use satellites, drones and ground sensors in a bid to tackle the spread of invasive aquatic weeds - a serious problem that damages vital water and food resources in Asia and Africa.
