Working List of Prairie Restricted (Specialist) Insects in Wisconsin (11/26/2015)
Working List of Prairie Restricted (Specialist) Insects in Wisconsin (11/26/2015) By Richard Henderson Research Ecologist, WI DNR Bureau of Science Services Summary This is a preliminary list of insects that are either well known, or likely, to be closely associated with Wisconsin’s original native prairie. These species are mostly dependent upon remnants of original prairie, or plantings/restorations of prairie where their hosts have been re-established (see discussion below), and thus are rarely found outside of these settings. The list also includes some species tied to native ecosystems that grade into prairie, such as savannas, sand barrens, fens, sedge meadow, and shallow marsh. The list is annotated with known host(s) of each insect, and the likelihood of its presence in the state (see key at end of list for specifics). This working list is a byproduct of a prairie invertebrate study I coordinated from1995-2005 that covered 6 Midwestern states and included 14 cooperators. The project surveyed insects on prairie remnants and investigated the effects of fire on those insects. It was funded in part by a series of grants from the US Fish and Wildlife Service. So far, the list has 475 species. However, this is a partial list at best, representing approximately only ¼ of the prairie-specialist insects likely present in the region (see discussion below). Significant input to this list is needed, as there are major taxa groups missing or greatly under represented. Such absence is not necessarily due to few or no prairie-specialists in those groups, but due more to lack of knowledge about life histories (at least published knowledge), unsettled taxonomy, and lack of taxonomic specialists currently working in those groups. -

Box 250 Pierre, SD 57501-0250 611416 West Hidalgo Tolleson, AZ 85353 1 Abstract Strategies that utilize lower than traditional doses of insecticides in combination with swaths of applied insecticide that leave untreated areas between each swath are one way to significantly reduce the cost of controlling grasshoppers on rangeland. By leaving untreated areas, this strategy provides reserves for naturally occurring biological control agents and facilitates an economical integrated management approach for dealing with damaging populations of grasshoppers on rangeland. This three year study was conducted in different locations and years to develop and demonstrate on a large scale operational level, the utility of reduced area / agent treatments (RAATs) for significantly reducing costs to manage damaging populations of grasshoppers. In 1997 these reduced agent/area treatments (RAATs) resulted in about 15% lower mortality than traditional treatments while reducing pesticide use and cost by 60% with malathion and 75% with carbaryl. -

Medler INTRODUCTION HIS bulletin attempts to present as accurate and complete a T guide to the leafhoppers of Minnesota as possible within the limits of the material available for study. It is realized that cer- tain groups could not be treated completely because of the lack of available material. Nevertheless, it is hoped that in its present form this treatise will serve as a convenient and useful manual for the systematic and economic worker concerned with the forms of the upper Mississippi Valley. In all cases a reference to the original description of the species and genus is given. Keys are included for the separation of species, genera, and supergeneric groups. In addition to the keys a brief diagnostic description of the important characters of each species is given. Extended descriptions or long lists of references have been omitted since citations to this literature are available from other sources if ac- tually needed (Van Duzee, 1917). -
Invertebrate Distribution and Diversity Assessment at the U. S. Army Pinon Canyon Maneuver Site a Report to the U
Invertebrate Distribution and Diversity Assessment at the U. S. Army Pinon Canyon Maneuver Site A report to the U. S. Army and U. S. Fish and Wildlife Service G. J. Michels, Jr., J. L. Newton, H. L. Lindon, and J. A. Brazille Texas AgriLife Research 2301 Experiment Station Road Bushland, TX 79012 2008 Report Introductory Notes The invertebrate survey in 2008 presented an interesting challenge. Extremely dry conditions prevailed throughout most of the adult activity period for the invertebrates and grass fires occurred several times throughout the summer. By visual assessment, plant resources were scarce compared to last year, with few green plants and almost no flowering plants. Eight habitats and nine sites continued to be sampled in 2008. The Ponderosa pine/ yellow indiangrass site was removed from the study after the low numbers of species and individuals collected there in 2007. All other sites from the 2007 survey were included in the 2008 survey. We also discontinued the collection of Coccinellidae in the 2008 survey, as only 98 individuals from four species were collected in 2007. Pitfall and malaise trapping were continued in the same way as the 2007 survey. Sweep net sampling was discontinued to allow time for Asilidae and Orthoptera timed surveys consisting of direct collection of individuals with a net. These surveys were conducted in the same way as the time constrained butterfly (Papilionidea and Hesperoidea) surveys, with 15-minute intervals for each taxanomic group. This was sucessful when individuals were present, but the dry summer made it difficult to assess the utility of these techniques because of overall low abundance of insects. -

The Effects of Native and Non-Native Grasses on Spiders, Their Prey, and Their Interactions
Spiders in California’s grassland mosaic: The effects of native and non-native grasses on spiders, their prey, and their interactions by Kirsten Elise Hill A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Environmental Science, Policy, and Management in the GRADUATE DIVISION of the University of California, Berkeley Committee in charge: Professor Joe R. McBride, Chair Professor Rosemary G. Gillespie Professor Mary E. Power Spring 2014 © 2014 Abstract Spiders in California’s grassland mosaic: The effects of native and non-native grasses on spiders, their prey, and their interactions by Kirsten Elise Hill Doctor of Philosophy in Environmental Science and Policy Management University of California, Berkeley Professor Joe R. McBride, Chair Found in nearly all terrestrial ecosystems, small in size and able to occupy a variety of hunting niches, spiders’ consumptive effects on other arthropods can have important impacts for ecosystems. This dissertation describes research into spider populations and their interactions with potential arthropod prey in California’s native and non-native grasslands. In meadows found in northern California, native and non-native grassland patches support different functional groups of arthropod predators, sap-feeders, pollinators, and scavengers and arthropod diversity is linked to native plant diversity. Wandering spiders’ ability to forage within the meadow’s interior is linked to the distance from the shaded woodland boundary. Native grasses offer a cooler conduit into the meadow interior than non-native annual grasses during midsummer heat. Juvenile spiders in particular, are more abundant in the more structurally complex native dominated areas of the grassland. -
INTRODUCTION This Catalog Presents the Archived Documentation Files for the Datasets Currently in the Konza Prairie LTER Site Database
INTRODUCTION This catalog presents the archived documentation files for the datasets currently in the Konza Prairie LTER site database. These datasets are affiliated with LTER scientists associated with the Konza Prairie LTER research program from 1981 to 1992. The purpose of this catalog is to assist scientists in the analysis and synthesis of this database. In addition to this catalog, a detailed methods manual documents the procedures used in collecting these data sets. The design of the current Konza Prairie LTER database is straightforward. All data sets are in ASCII format (with exception of GIS coverages; See GIS01). The entire database is available at: http://www.konza.ksu.edu. The database is divided into subgroups. The subgroups correspond to the research groups that have developed on Konza or represents the data set. They are: Abiotic, Belowground, Consumer, Nutrient, Organic, Other, and Woody. The first letter of the data set code indicates which subgroup the file is in. The extension of the file name represents the year of the data set. For example the data set associated with prairie precipitation for 1986 (data set code APT01), is found in the subgroup abiotic under the file name of apt011.86. Data sets that do not conform to this naming procedure are listed in the abstract section of their corresponding data set code description. For the most part, these data sets involve data that comes from other sources than LTER investigators (e.g. USGS flow data or NADP). The subgroup woody contains the files of the dataset code PWV01.The subgroup Other is reserved for datasets that do not conform to the naming procedures (for now, datasets from the water supplementation experiment (WAT01) are here). -
