Research offers evidence that the economic costs associated with invasive species is in large part determined by the response time between arrival of a pest and the beginning of eradication or control efforts.

Both scientists and regulators have had a lot to say about the growing problem of herbicide resistance and how weed management techniques need to change in response. But there have been few organized opportunities for farmers to make their voices heard and to share their experiences in managing herbicide-resistant weeds.
The Movement to Rename Species. The common names of some species have not aged well. These scientists want to change them. The impact of a name that offends can be far-reaching.
The Great Lakes Fishery Commission today reported that populations of the invasive, parasitic sea lamprey remain at near-historic lows, below targets, in Lakes Michigan and Ontario, and above target, but holding steady, in Lakes Huron, Superior and Erie. Sea lamprey populations in Lake Huron are close to target levels and have been holding steady for the past five years. Abundances in Lakes Superior and Erie remain above target but have also decreased significantly since the near-record highs observed in 2017. Sea lampreys are the worst of the alien species to invade the Great Lakes. Before control, sea lampreys destroyed many times the human fish catch. Today, sea lamprey control is the foundation of the $7 billion Great Lakes fishery. The Commission and its partners are encouraged by the overall decrease in abundance of sea lampreys throughout the Great Lakes basin during 2019, but caution that environmental conditions, such as a prolonged spring and high precipitation events, contributed to the decrease.
Discover Life in America, the nonprofit research partner of Great Smoky Mountains National Park, is inviting the public to participate in its latest project, Smokies Most Wanted, an initiative that allows visitors to help conserve park species by recording sightings of animals, plants and other organisms from their smartphones. Powered by the nature app iNaturalist, Smokies Most Wanted encourages park visitors to document any organism they encounter while hiking, camping, or otherwise enjoying the park — from birds to wildflowers, insects to lichens. DLiA then uses the data collected through iNaturalist for a variety of functions, like recording new park species or detecting invasive ones, learning about under-studied or rare species, and mapping species across the park.
