Data on intraguild predation of arthropods on the tarweed Hemizonia congesta. Arthropod counts (predators, herbivores, etc) and counts of entrapped arthropod corpses on focal plants in an experiment manipulating arthropod carrion amount and plant damage. Quantifications of plant damage and reproduction are presented.

These data provide information about all vegetation structure measurements (except shrub point-centered quarter measures) taken on Arizona Grasshopper Sparrow nest plots in 2011 to 2013 on two study sites - Audubon Appleton-Whittell Research Ranch, and BLM Las Cienegas NCA - Davis Pasture - in southeastern Arizona.

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.

These data provide information about vegetation structure and composition associated with Arizona Grasshopper Sparrow territories, nest plots, and random transects on two study sites - Audubon Appleton-Whittell Research Ranch and BLM Las Cienegas National Conservation Area (NCA) - Davis Pasture - in southeastern Arizona. Data were collected from 2009 through 2013. These are data associated with Ruth and Skagen (2017) cited above.

This shapefile documents the arthropod field survey points in Assateague Island National Seashore between 2005 and 2007. Habitat information is included in an accompanying NPS Access database. This study is part of the Inventory and Monitoring Program of the Northeast Coastal and Barrier Network.

We compared pollinator diversity derived from environmental DNA (eDNA) extracted from flowers and DNA extracted from pulverized bulk samples of insects collected from vane traps deployed at the same sites. We used three metabarcoding primers, two of which target arthropods generally (COI-Jusino and 16S-Marquina) and one that targets bumblebees (Bombus spp., COI-Milam). Across methods, we detected 77 insect families from 9 orders. The COI-Jusino marker amplified the highest taxonomic diversity compared to 16S-Marquina and COI-Milam. More ASVs were recovered from vane traps (blue: 1357, yellow: 1542) than flowers (245), but only 23% of families and 13% of genera were shared among methods, indicating that flowers and blue and yellow vane traps may each sample different parts of the available arthropod community. Of 29 flowers with known bee visitations, only 10 had bee detections, and incomplete reference databases hindered assignment to species.
