Duane Moser and DRI’s Environmental Microbiology Lab are working to protect rare Southwestern desert fish from invasive species.

Captured at the Las Vegas Wetlands Park, this Australian redclaw crayfish underscores the need for rapid eDNA detection to safeguard fragile ecosystems.

🚢 Guess how many vessel inspections we completed last year?

2,068 inspections!

Through our Marine Invasive Species Program, we inspect at least 25% of vessel arrivals to help prevent the spread of invasive species in CA waters.

The Surprising Intersection of Marine Biosecurity and Public Health From the introduction of deadly microbes into seafood to the clogging of cooling systems of a nuclear power plant, marine invasive species are more than just costly pests that harm food webs.

Marine invasive species don’t just affect oceans—they can have impacts far beyond the sea, impacting things like food safety, infrastructure and public health. Learn more about these impacts in today’s #NISAW webinar.

Pictures of two faucet snails from different angles to show identification features on a ruler to show scale with the following text: Invasive Species Spotlight: Faucet Snail / Mud Bithynia (Bithynia tentaculata) Key Identification Features: Small shell approximately 12-15 mm at full size with a rounded spire of 5-6 whorls and the shell opening (aperture) less than half the total height of the shell Shell color can vary from shiny light brown to black “Right-handed” (dextral) shell opening with covering called an operculum that is whitish and calcified with a pattern of concentric rings

Species spotlight for National Invasive Species Awareness Week. Invasive faucet snails are a growing concern in the Champlain Basin and Great Lakes region and can outcompete native snails, clog drain and intake pipes, and spread parasites to birds.

Black text on a blue background which reads: Invasive Species Spotlight: Banded Mystery Snail (Callinina georgiana) above a photo of a large banded mystery snail and six tiny juvenile snails on a ruler for scale. Below it reads: Key Identification Features: 1) Spiral shell with a rounded shape and 3-5 whorls, 2) "Right-handed" (dextral) shell opening with covering called an operculum, 3) You may notice lots of tiny snails nearby or inside the shells of dead adult snails because these snails give birth to live offspring instead of laying eggs.

Invasive Species Spotlight!
When introduced to a new place, Banded Mystery Snails (Callinina georgiana) can cause damage by:
❌outcompeting native snails
❌eating fish eggs
❌spreading parasites to birds
❌overgrazing vegetation

Beech Leaf Disease (BLD) & Beech Bark Disease (BBD) are invasive threats to beech trees.

BLD, caused by a nematode, and BBD, caused by beech scale insects and pathogens, both lead to tree death. #NISAW #InvasiveSpecies #entomology 🧪 🌎🍁
