Weed Images: The Source for Images of Weeds and Weed Management in Agriculture

    A joint project of The University of Georgia - Warnell School of Forestry and Natural Resources, College of Agricultural and Environmental Sciences - Department of Entomology, Center for Invasive Species and Ecosystem Health, Weed Science Society of America and the USDA/APHIS Identification Technology Program, [Weed Images](https://www.weedimages.org/) image categories include: Habit: Aquatics, Herbs/Forbs, Grasses, Shrubs, Trees, Vines; Herbicides: Mechanism of Action, HRAC or WSSA Group; Most Troublesome and Most Common Weed Lists.

    Forestry Images: The Source for Forest Health and Silviculture Images

      A joint project between University of Georgia - Bugwood Network and the U.S. Department of Agriculture, [Forestry Images](https://www.forestryimages.org/) image categories include: Forest Pests; Trees, Plants, and Stand Types; Silvicultural Practices; Urban Forestry; Wildlife; People, Places and Scenes.

      National Integrated Pest Management (IPM) Database - IPMdata

        Integrated Pest Management (IPM) is a science-based, decision-making process that identifies and reduces risks from pests and pest management related strategies. IPM coordinates the use of pest biology, environmental information, and available technology to prevent unacceptable levels of pest damage by the most economical means, while minimizing risk to people, property, resources, and the environment. IPM provides an effective strategy for managing pests in all arenas from developed agricultural, residential, and public lands to natural and wilderness areas. IPM provides an effective, all encompassing, low-risk approach to protect resources and people from pests.

        Systema Dipterorum

          Two-winged insects or Diptera comprise 12% of the planetary biota, and the Systema Dipterorum is an authoritative source for their names. Systema Dipterorum contains all names proposed for extant and extinct Diptera and it is a source for information about those names. The two main components of Systema Dipterorum are the Nomenclator and the References database. By providing authoritative information about dipteran names, Systema Dipterorum is the necessary framework for organizing, interpreting and integrating current and future data, information and knowledge about two-winged insects.

          Invasive and Exotic Species of North America - Invasive.org

            [Invasive.org](https://www.invasive.org/) is a joint project between University of Georgia's Bugwood Network and the U.S. Department of Agriculture. Over 8,300 images, including over 1,000 new images of invasive/exotic/noxious plant, insect, pathogen and other species (including many weeds) and their biological control agents, taken by over 250 photographers. Most images were digitized from high-resolution 35mm slides. Multiple levels of jpeg format images are downloadable and may be copied and used for any non-profit, educational purpose with appropriate credit and copyright notice. Although most images are North American in nature, the system also contains images of organisms that are "Non-U.S. Natives", or are considered to be "U.S. Invasives."

            National Invertebrate Genetic Resources

              Insects impact American agriculture both as destructive and beneficial organisms. Insect pests, parasites, predators, products, and pollinators are all economically important. It is critically important to distinguish between different species, races, stocks, strains, biotypes, and other genetic entities and to document their different interactions with agriculture and the environment. The goals of the National Invertebrate Genetic Resources Program include: 1. Preservation of reference specimens 2. Maintenance of genetically important germplasm 3. Documentation of specific insect stocks 4. Management of databases 5. Distribution of material to researchers and breeders.

              Cacao Genome Database

                The release of the cacao genome sequence will provide researchers with access to the latest genomic tools, enabling more efficient research and accelerating the breeding process, thereby expediting the release of superior cacao cultivars. The sequenced genotype, Matina 1-6, is representative of the genetic background most commonly found in the cacao producing countries, enabling results to be applied immediately and broadly to current commercial cultivars.  Matina 1-6 is highly homozygous which greatly reduces the complexity of the sequence assembly process. While the sequence provided is a preliminary release, it already covers 92% of the genome, with approximately 35,000 genes. We will continue to refine the assembly and annotation, working toward a complete finished sequence.

                ARS Microbial Genomic Sequence Database Server

                  This database server is supported in fulfilment of the research mission of the Mycotoxin Prevention and Applied Microbiology Research Unit at the National Center for Agricultural Utilization Research in Peoria, Illinois. The linked website provides access to gene sequence databases for various groups of microorganisms, such as Streptomyces species or Aspergillus species and their relatives, that are the product of ARS research programs. The sequence databases are organized in the BIGSdb (Bacterial Isolate Genomic Sequence Database) software package developed by Keith Jolley and Martin Maiden at Oxford University.

                  Data from: Underestimation of N2O emissions in a comparison of the DayCent, DNDC, and EPIC 1 models

                    Process-based models are increasingly used to study mass and energy fluxes from agro-ecosystems, including nitrous oxide (N2O) emissions from agricultural fields. This data set is the output of three process-based models – DayCent, DNDC, and EPIC – which were used to simulate fluxes of N2O from dairy farm soils. The individual models' output and the ensemble mean output were evaluated against field observations from two agricultural research stations in Arlington, WI and Marshfield, WI. These sites utilize cropping systems and nitrogen fertilizer management strategies common to Midwest dairy farms.
