Scientists Bite Back at Invasive Mosquitos, Work for Hawaiian Honeycreeper Conservation
-

DOI. United States Geological Survey.

Biologists from the U.S. Geological Survey are racing the clock to pull four species of native Hawaiian Honeycreeper forest birds back from the brink of extinction. Factors such as habitat loss, invasive species, and non-native predators have been fueling the birds' decline for centuries. However, introduced diseases, particularly avian malaria spread through mosquitos, which are not native to the Hawaiian Islands, coupled with climate change, are the greatest threat facing Hawaiian forest birds today.
"As the climate warms and more mosquitoes move into the once malaria-free regions of the mountains, healthy birds are running out of places to escape the cycle of infection," said Eben Paxton, a research ecologist with the USGS Pacific Island Ecosystems Research Center (PIERC) in Hawai'i. Now, PIERC biologists are working with a range of partners, including other Interior Department bureaus and the Birds Not Mosquitos Coalition, to intercept the disease cycle using a novel conservation tool.

Scientists Develop a Plan to Manage Lionfish Populations in the Mediterranean
-
Apr 11, 2022
-
University of Plymouth (United Kingdom).
-
Scientists have published a series of recommendations to enable communities and managers to minimise the impact of lionfish in the Mediterranean Sea. The invasive species was first noticed off the coast of the Lebanon in 2012, with sightings since recorded as far west as Sicily, and north into the Adriatic Sea off Croatia. More entered in 2015 due to the enlargement and deepening of the Suez Canal, with their spread unimpeded due to a lack of common predators. Researchers in the UK and Cyprus have said increasing lionfish densities – combined with the species' generalist diet and consumption of ecologically and socio-economically important fish – has the potential to result in further disruption of an already stressed marine environment. They have now published a Guide to Lionfish Management in the Mediterranean [PDF, 8.0 MB], which features a series of recommendations through which they hope lionfish populations can be managed.

-
USDA. Agricultural Research Service.
-
A map identifying the areas suitable for establishment of the spotted lanternfly (SLF) in the United States and other countries has been published in the Journal of Economic Entomology by Agricultural Research Service scientists. The SLF, originally from China, has spread to Korea and Japan, and has been found most recently in the United States in Pennsylvania, New Jersey, Virginia and Delaware. These insects are pests of many agricultural crops including almonds, apples, blueberries, cherries, peaches, grapes and hops as well as hardwoods such as oak, walnut and poplar, among others. USDA and State partners have been working to contain SLF populations since 2014. There is the potential for far reaching economic damage if the SLF becomes widely established in the United States.

May 2024
-
USDA. FS. Northern Research Station. Rooted in Research.
-
Seed banks can provide insight into a forest’s past and give land managers valuable information to help them plan for the forest’s future. For example, knowing which species may germinate after future fires is valuable, especially when nonnative invasive species in the seed bank could proliferate quickly following disturbances.
In this study, researchers analyzed the species composition of buried seeds and extant vegetation present in areas that have faced differing fire conditions over many years on the Monongahela National Forest in West Virginia.

Service Proposes to List the Tricolored Bat as Endangered Under the Endangered Species Act: Ongoing spread of white-nose syndrome is primary threat, increasing risk of extinction
-
Sep 13, 2022
-
DOI. Fish and Wildlife Service.
-
The U.S. Fish and Wildlife Service announced a proposal to list the tricolored bat as endangered under the Endangered Species Act (ESA). The species faces extinction due primarily to the range-wide impacts of white-nose syndrome, a deadly disease affecting cave-dwelling bats across the continent.
Bats are essential for healthy ecosystems and contribute at least $3 billion annually to the U.S. agriculture economy through pest control and pollination. The growing extinction crisis highlights the importance of the ESA and efforts to conserve species before declines become irreversible.

Jun 2023
-
USDA. FS. Northern Research Station.
-
The spongy moth, (Lymantria dispar), formerly known as the "gypsy moth," continues to spread throughout North America, threatening deciduous trees and impacting humans. This non-native, foliage-feeding insect currently occupies only about one-third of its possible host distribution in the United States. Efforts to reduce its impact and spread represent one of the largest and most successful federal and state agency integrated pest management programs against a forest pest.
This new General Technical Report (GTR), published by the Northern Research Station, synthesizes information about the Slow the Spread Program, its accomplishments, and provides a framework for future landscape-level integrated pest management.

Idaho Department of Agriculture.
-
The Idaho Department of Agriculture (ISDA) has confirmed the presence of quagga mussel in the Mid-Snake River. Quagga mussel larvae was first detected in the Snake River near Twin Falls on September 18, 2023, by routine monitoring conducted by the ISDA. If nothing were done, quagga mussels would quickly take over waterways. They would irreparably harm water use in Idaho. These findings mark the first time a rapid response plan has been put into action for quagga mussels in Idaho.

USDA. Blog.
-
USDA scientists have discovered that the spotted lanternfly, an invasive threat to fruit crops and many trees, may have an Achilles heel – an attraction to vibration. A native of China, the insect was discovered in Pennsylvania in 2014 and has since spread to 13 other states. Though beautiful as an adult, the insect is a voracious eater that feeds on woody and ornamental trees as well as a wide variety of crops and plants. Left unchecked, Pennsylvania alone could lose hundreds of millions of dollars and thousands of jobs.
Richard Mankin, an entomologist with the USDA Agricultural Research Service’s Center for Medical, Agricultural, and Veterinary Entomology in Gainesville, FL, and colleagues found a new way to potentially corral and control the pests. Their research was published in the Journal of Economic Entomology.

Deceptively delicate and fragile in appearance, the Eurasian watermilfoil forms thick mats in shallow areas of a lake, quickly growing and spreading to block sunlight, killing off native aquatic plants that fish and other underwater species rely on for food and shelter. In North America, the plant threatens the diversity and abundance of native plants as well as the ecological balance of lakes and ponds, which in turn adversely affects recreational opportunities. If left unchecked, invasive watermilfoil will spread through a lake, or even to other lakes by transmission. An expert team of USDA Forest Service divers with invasive species and aquatics expertise is focused on rooting out the plant.

Love them or hate them, there's no doubt the European Starling is a wildly successful bird. A new study from the Cornell Lab of Ornithology examines this non-native species from the inside out. What exactly happened at the genetic level as the starling population exploded from just 80 birds released in New York City's Central Park in 1890, peaking at an estimated 200 million breeding adults spread all across North America? The study appears in the journal Molecular Ecology - "Environmental correlates of genetic variation in the invasive European starling in North America."
