  • Chesapeake Channa (Northern Snakehead) Could Spawn More than Once a Year in Upper Bay, Maryland DNR Study Finds

    • Sep 18, 2024
    • Maryland Department of Natural Resources.

    • A study conducted by Maryland Department of Natural Resources Biologist Dr. Joseph Love illuminates one of the biological factors that could be contributing to Chesapeake Channa’s efficient spread through Maryland’s waters. The study, published in the July 2024 edition of Northeastern Naturalist, found that the majority of female Chesapeake Channa, also known as northern snakehead, collected from the upper Chesapeake Bay carried eggs in two distinct sizes, suggesting those fish could spawn twice a year.

    • Chinese privet (Ligustrum sinense) is one of the worst invasive plants in the South. It dominates the shrub layer and often becomes the only shrub underneath trees, especially in streamside areas. But insects and spiders living in fallen leaves and leaf litter were not affected by a privet invasion in Georgia, as a recent study shows.

  • Choose Copi: Eat Well and Do Good - State of Illinois Renames and Rebrands Asian Carp

    • Jun 22, 2022
    • Illinois Department of Resources.

    • Following more than two years of consumer research and planning, the State of Illinois unveiled "Copi," the new name for Asian carp, which is a play on “copious” – as that’s exactly what these fish are. By one estimate, 20 million to 50 million pounds of Copi could be harvested from the Illinois River alone each year, with hundreds of millions more in waterways from the Midwest to the Gulf Coast. The new name and brand are designed to address public misconceptions about this delicious top-feeding fish, which is overrunning Midwest waterways.

      Copi are mild, clean-tasting fish with heart-healthy omega-3s and very low levels of mercury. Increased consumption will help to stop them from decimating other fish populations in the Great Lakes and restore an ecological balance to waterways down stream.

  • Citizen Science and the Invasive Fig Buttercup

    • South Carolina Native Plant Society.

    • Fig Buttercup (Ficaria verna, formerly Ranunculus ficaria) is an early-blooming perennial with origins in Europe and northern Africa. It is also called Lesser Celandine, and it is sometimes confused with Marsh Marigold (Caltha palustris). More recently, its behavior has transitioned or is in the process of transitioning to that of an aggressive invasive species that threatens bottomlands throughout its adopted range. Even after its invasiveness was recognized, many people did not anticipate that it would behave invasively in the South, as it has begun to do. Be a Citizen Scientist— We are asking you to help us scout areas near you where it is likely to be found, so that emerging infestations can be documented, treated and monitored.
