Arthropod abundance across a fire severity gradient beneath potential cover objects throughout the Jemez Mountains, New Mexico, USA 2023-2024.
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).

Slash Pile Characteristics and their Relationship to Habitat for Sacramento Mountain Salamanders, New Mexico USA
공공데이터포털
This data package contains six tables: 1) slash pile characteristics, 2) soil moisture and temperature below and nearby slash piles, 3) measurements of individual logs within slash piles, 4) characteristics of log cover objects nearby slash piles, 5) locations and body measurements of Sacramento Mountain salamanders (Aneides hardii) found under or within slash piles or individual log cover objects near slash piles, and 6) characteristics of log cover objects searched in a 1.4 hectare area encompassing slash piles, including body measurements of Sacramento Mountain salamanders found under these objects. Data were collected over a three-day period in late August 2021, in the Lincoln National Forest of south-central New Mexico, United States. Sixteen slash piles and associated environmental variables were measured to assess the potential for slash piles to serve as habitat for Sacramento Mountain salamanders.
Inventory of amphibians and reptiles at Death Valley National Park in 2002-2004 - Data Package (PUBLIC)
공공데이터포털
An inventory of amphibians and reptiles was conducted at Death Valley National Park (DEVA) in 2002- 2004 as part of the National Park Service Inventory and Monitoring Program in the Mojave Desert Network. Objectives for this inventory were to: 1) Inventory and document the occurrence of reptile and amphibian species occurring at DEVA, primarily within priority sampling areas, with the goal of documenting at least 90% of the species present; 2) document (through collection or museum specimen and literature review) one voucher specimen for each species identified; 3) provide a GIS-referenced list of sensitive species that are federally or state listed, rare, or worthy of special consideration that occur within priority sampling locations; 4) describe park-wide distribution of federally- or state-listed, rare, or special concern species; 5) enter all species data into the National Park Service NPSpecies database; and 6) provide all deliverables as outlined in the Mojave Inventory and Monitoring Network Biological Inventory Study Plan. Methods included daytime and nighttime visual encounter surveys, road driving, and pitfall trapping. Survey effort was concentrated in predetermined priority sampling areas, as well as in areas with a high potential for detecting undocumented species. 37 species were recorded during surveys, including two species new to the park. During literature review and museum specimen database searches, study authors recorded three additional species from DEVA, elevating the documented species list to 40 (four amphibians and 36 reptiles). Based on these surveys, as well as literature and museum specimen review, this study estimates an overall inventory completeness of 92% for Death Valley and an inventory completeness of 73% for amphibians and 95% for reptiles.

USGS 2017 BRalston Ground Dwelling Arthropod Composition Data v3
공공데이터포털
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.
Arthropod Abundance Data from the Colville River Delta, Alaska
공공데이터포털
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.
