These data were compiled from pitfall traps deployed at three sites, along a 25 kilometers (km) stretch of the Colorado River, immediately downstream of Glen Canyon Dam, in Glen Canyon National Recreation Area. Each site had both pre and post-dam riparian habitats present. The purpose of the sampling was to determine if arthropod abundance, diversity and feeding guilds differed between habitats. Sampling for ground-dwelling arthropods using pitfall traps occurred continuously between June 17 and September 9, 2009. The site numbering proceeds from Glen Canyon Dam to Lees Ferry. Transects were composed of 10 pitfall traps approximately 10 meters apart in a line parallel with the river in both zones (Upper riparian zone (pre-dam habitat) and Lower riparian zone (post-dam habitat). Sample processing of three target groups occurred in labs at Northern Arizona University (Coleoptera and Hymenoptera, mostly ants) and University of New Mexico (Class Arachnida, mostly spiders). Species were classified into one of four feeding guilds (omnivores, detritivores, predators, and herbivores) based on published characteristics reported at the level of genus or family.

,Data files for manuscript titled "New Record of the Pavement Ant, Tetramorium immigrans (Hymenoptera: Formicidae), in South Dakota with Notes on its Thermal Tolerance and Geographic Distribution".,Excel file with 7 tabs: Metadata; CTmin, CTmax, Knock-down, Chill coma, Specimen data, Observation data,Data description: Raw data for county observations/museum collections and thermal traits of Tetramorium immigrans. The data for observations/museum collections were collated from >100 years of publicly available information on the Global Biodiversity Information Facility (GBIF) and the Symbiota Collections of Arthropods Network (SCAN). Presence/absence values from these digital repositories were assigned to current county or county equivalent federal information processing system (FIPS) codes to create an updated distributional map. Thermal trait data that included critical thermal maximum and minimum, knock-down resistance, and chill coma recovery were empirically determined from specimens collected in Brookings, SD in 2022 and 2023. Methods for each assay are listed in the main text.,Abstract from paper: The pavement ant, Tetramorium immigrans Santschi, is an abundant and widespread species across large portions of the United States. Yet despite its current distribution in Northeastern, Midwestern, Pacific, and Western states, there is a surprising lack of records from the Great Plains. Here we present an updated county list of T. immigrans from museum collections and research grade observations (459 counties; ~15% of US counties), highlighting the first records from one Great Plains state—South Dakota. Observations on community science platforms since 2006 have undoubtedly increased the awareness of T. immigrans (+329 counties; ~72% of all county records), however we posit that such platforms may also highlight the dispersal limitations of this species into the less urban, colder Northern Great Plains states of Montana, Nebraska, North Dakota, South Dakota, and Wyoming (~5% of 291 counties). As such, we offer novel information on T. immigrans’ thermal biology including measurements of critical thermal limits, knock-down resistance, and chill coma recovery. While T. immigrans can likely tolerate the warm summer temperatures found in South Dakota due to its heat tolerance hovering around 46 °C, its lower ability to tolerate cold winter conditions may be a possible mechanism for its limited dispersal.,

This data release contains information on the seasonal diversity and abundance of arthropods collected at the Colville River Delta, Alaska, 2011-2012 and 2014-2107. Researchers with the US Geological Survey began studying the reproductive ecology of birds at a site on the Colville River near the Beaufort Sea coast in 2011. Researchers concurrently collected arthropods at 3-day intervals to understand the relationship between the seasonal abundance of arthropods and the reproductive output of insectivorous birds.

Data containing field observations of potential Jemez Mountains salamander (JMS; Plethodon neomexicanus) cover objects and characteristics of underlying soils, concurrent with arthropod data collected from pitfall traps beneath selected cover objects in salamander historic habitat located in the Jemez Mountains, New Mexico from 2023-2024. We sampled potential salamander prey items beneath potential cover objects and measured abiotic characteristics of likely importance to JMS and soil arthropods. Wildfires in Jemez Mountains salamander historic habitat can affect cover availability, alter soil abiotic factors, and influence prey base. We collected data on the effect of fire severity on salamander potential cover objects with an emphasis on Coleoptera (beetles), a main prey item, across a burn severity gradient. Furthermore, we investigated how cover object characteristics influence arthropod communities by deploying novel pitfall traps beneath potential cover objects. Pitfall traps deployed underneath selected cover objects were re-sampled biweekly across a fire severity gradient of unburned, low, and medium/high severity sites within historic JMS range, throughout two consecutive summer monsoon seasons, when salamanders are likely to be more active on the soil surface This data release includes arthropod data and cover object characteristics collected solely from 2023, including supplementary soil data that was collected in 2024. The data release includes 3 .csv files related to field observations: 1) Potential salamander cover object characteristics including type of cover, cover object size, embeddedness, decay class, canopy cover, soil moisture, soil C:N ratio (cover_object_data.csv), 2) Pitfall trap count data in which arthropods were identified to the coarsest taxonomic unit (varies by taxa; coarse_arthropod_data.csv), 3) Pitfall trap beetle count data identified to the lowest practical taxonomic unit (beetle_lptu_data.csv).

,This data package was produced by researchers working on the Shortgrass Steppe Long Term Ecological Research (SGS-LTER) Project, administered at Colorado State University. Long-term datasets and background information (proposals, reports, photographs, etc.) on the SGS-LTER project are contained in a comprehensive project collection within the Digital Collections of Colorado (http://digitool.library.colostate.edu/R/?func=collections&collection_id=3429). The data table and associated metadata document, which is generated in Ecological Metadata Language, may be available through other repositories serving the ecological research community and represent components of the larger SGS-LTER project collection.,,

Grasshopper biomass and species-level diversity was recorded at locations on and off prairie dog colonies in the Thunder Basin National Grassland, Wyoming, USA. Data were collected in order to record the association between grasshopper communities and prairie dog colonies.
