  • ARS Research News - Sharing is Caring with Fire Ant Venom

    • Dec 7, 2022
    • USDA. Agricultural Research Service.

    • Venom is associated with being harmful, but red imported fire ants are using their venom for its medicinal benefits by sharing the toxic substance with their nestmates, according to a study published in the Journal of Insect Physiology. Agricultural Research Service (ARS) scientists from the agency's Biological Control of Pests Research Unit and Southern Insect Management Research Unit in Stoneville, Mississippi, discovered a new way that fire ants use their venom to prevent diseases in their colonies.

    • Nov 29, 2022
    • DOI. Fish and Wildlife Service.

    • The U.S. Fish and Wildlife Service announced a final rule to reclassify the northern long-eared bat as endangered under the Endangered Species Act (ESA). The bat, listed as threatened in 2015, now faces extinction due to the rangewide impacts of white-nose syndrome, a deadly disease affecting hibernating bats across North America. The rule takes effect on January 30, 2023.

  • 2022 Research Highlights for the Northern Research Station

    • Dec 2022
    • USDA. FS. Northern Research Station.

    • The Northern Research Station delivers science solutions for a sustainable future, pursues collaborative research-based solutions for complex challenges, and informs land management decisions. These research highlights are just a small part of the excellent work done by the Station's researchers this year. From understanding the impacts of climate change, invasive species, and altered fire regimes, to providing science to support ecosystem management, to developing new tools for restoration and reforestation, this work will help sustain the health, diversity, and productivity of the Nation's forests and grasslands.

  • USDA Seeks Public Input on Draft Environmental Documents for Deregulation of American Chestnut Developed Using Genetic Engineering

    • Nov 9, 2022
    • USDA. Animal and Plant Health Inspection Service.

    • The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is inviting public comment on two draft documents involving a petition from the State University of New York College of Environmental Science and Forestry (SUNY) seeking deregulation of an American chestnut variety modified for tolerance to chestnut blight. The first document is a draft Environmental Impact Statement (DEIS) that examines the potential environmental impacts, and the second is a draft Plant Pest Risk Assessment (DPPRA) that considers potential plants pest risks.

      Beginning November 10, 2022, members of the public can submit comments through December 27, 2022, by going to and entering “APHIS-2020-0030” into the Search field.

  • IUCN Leads Development of a New Manual for the Management of Invasive Alien Species in the EU, Incorporating Animal Welfare

    • Nov 18, 2022
    • International Union for the Conservation of Nature.

    • Led by IUCN, a manual to support EU Member States and other stakeholders with incorporating animal welfare into their management of invasive alien species (IAS) of Union concern has been published. The publication, "Manual for the management of vertebrate invasive alien species of Union concern, incorporating animal welfare [PDF, 5.7 MB]", presents all measures that are available to eradicate and control the 22 vertebrate IAS included in the EU Regulation on IAS (listed as of December 2021). For each measure, information on their costs, effectiveness, side effects, and crucially, on their impacts upon animal welfare is provided, alongside case studies on their application.

  • United States Register of Introduced and Invasive Species (US-RIIS)

    • Nov 4, 2022
    • DOI. United States Geological Survey.

    • Updated version 2.0, released Nov 4, 2022.

      Introduced (non-native) species that becomes established may eventually become invasive, so tracking introduced species provides a baseline for effective modeling of species trends and interactions, geospatially and temporally.

      The United States Register of Introduced and Invasive Species (US-RIIS) is comprised of three lists, one each for Alaska, Hawaii, and the conterminous United States. Each list includes introduced (non-native), established (reproducing) taxa that: are, or may become, invasive (harmful) in the locality; are not known to be harmful there; and/or have been used for biological control in the locality.

      To be included in the US-RIIS, a taxon must be non-native everywhere in the locality and established (reproducing) anywhere in the locality. Native pest species are not included. The US-RIIS builds on a previous dataset, A Comprehensive List of Non-Native Species Established in Three Major Regions of the U.S.: Version 3.0 (Simpson et al., 2020). An Open-File Report 2018-1156, 15 p., related to the predecessor of the US-RIIS:

  • First Study to Track a Wild Bird Known to Have Highly Pathogenic Avian Influenza

    • Oct 26, 2022
    • DOI. United States Geological Survey.

    • For the first time, scientists have tracked the movement of a wild bird known to be infected with highly pathogenic avian influenza in North America. The new research, led by the U.S. Geological Survey, can help improve estimates of when and where the virus could spread in the environment and to other birds.

  • Bipartisan Infrastructure Law Investments Combine Science and Technology to Track Biological Threats in US Waters

    • Nov 9, 2022
    • DOI. United States Geological Survey.

    • The U.S. Geological Survey announced it has signed a cooperative agreement with the Monterey Bay Aquarium Research Institute, or MBARI, to develop portable robotic DNA samplers capable of independently monitoring for living threats in the rivers and streams without constant support from researchers.

      With new investments from President Biden’s Bipartisan Infrastructure Law, the partnership will help advance detection of invasive species, pathogens and parasites which cause ecological and economic damage to aquatic systems. These organisms can wreak havoc on our waterways, threaten commercial and recreational fishing industries and promote the spread of zoonotic diseases that can impact humans.

  • Minnesota DNR Proposes Classifying 13 Invasive Plants, Animals as Prohibited

    • Oct 31, 2022
    • Minnesota Department of Natural Resources.

    • The Minnesota Department of Natural Resources is accepting public comment through Dec 9, 2022 on its proposal to classify 13 high-risk invasive aquatic plants, fish and invertebrates as prohibited. The DNR classifies invasive species as prohibited to prevent their introduction and spread in Minnesota, and to protect the state’s environment, economy, natural resources and outdoor recreation. More information on these species can be found on the AIS Classification page of the DNR website.

    • USDA. Animal and Plant Health Inspection Service.

    • The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has developed a publicly available dashboard that displays the results from nation-wide avian influenza virus (AIV) monitoring in wild bird populations. The dashboard may be found at

      Data presented in the dashboard can identify increased AIV risk and can provide information to poultry producers, wildlife managers, and members of the public on AIV activity in their area.
