Small Mammal Demographic Data

Abstract:

This file contains mark/recapture trapping data collected from 2013-present on permanently established small mammal trapping webs in the creosote-shrubland ecotone on the Sevilleta National Wildlife Refuge in central New Mexico. The two trapping webs are sampled for 3 consecutive nights once per month following the new moon. Each trapping web consists of 145 rebar stakes, 12 spokes originating from a central rebar point, each containing 12 rebars each. The first 4 stakes of the spoke are 5m apart, with the rest being 10m apart for a total of 100m per spoke (200m diameter).

Demographic data is collected from each captured animal including age, sex, species, trap location, and reproductive status. Each animal is marked with a unique ear or radio frequency identification (RFID) tag and tissue samples (hair, whiskers, blood and fecal) are collected from each individual once per month.

Demographic Findings: From 2013–2023, the program captured an average of 432 unique individuals per year across >10 species from two rodent families, Heteromyidae and Cricetidae. Heteromyids are the most abundant (~77% of captures), with Perognathus flavus (51%), Dipodomys merriami (11%), D. ordii (11%), and D. spectabilis (4%) dominating the community. Recapture rates for these species are >75%, generating longitudinal data on survival.

Methods and protocols used in the collection of this data package

Description:

Trapping Frequency

Trapping bouts occur during the months of March - November (weather permitting). Trapping bouts consist of three consecutive nights of baiting/setting traps and 3 mornings of checking traps/processing animals that are captured. The dates of these bouts coincide with the new moon when trap catch rate is highest in target species.

Trap Count

Each trapping web consists of 145 rebar stakes with a trap at each stake, 12 spokes originating from a central rebar point, each containing 12 rebars each. The first 4 stakes of the spoke are 5m apart, with the rest being 10m apart for a total of 100m per spoke (200m diameter).

Total traps set per night: 290

Setting Traps

The Sherman traps remain at the field site positioned on the trapping webs in between sampling bouts. Traps are opened and baited within an hour of sunset. The bait is a mixture of peanut butter, oats, and bird seed. Before baiting, ensure that the trap is performing correctly and set with the correct sensitivity. The latter requires being shown the preferred sensitivity by LTER staff in the field. Batting (cotton insulation) is added when the low is below 45°F or below 50°F if precipitation or high wind is expected. If both high wind and precipitation is expected, then batting must be added regardless of temperature. Temperature cutoff to call off trapping bouts is strict at 35°F.

Trap Collection

After traps have been set, the next day within ~1 hour of sunrise, traps are collected (if they have an animal) or closed (if they contain no animal) and transported back to the Sevilleta Field Station.

Processing

Each individual animal is outfitted with a Radio Frequency Passive Integrated Transponder (PIT) tag for individual animal identification by a trained team member. Captured animals will be marked as either a “new” animal or a “familiar” animal, denoting whether they have been seen by the program in prior bouts. A trained team member collects demographic information (species, weight, sex, location and reproductive stage) from each individual animal and this data is recorded right away in two locations (physical and digital). If the processing team member is unsure of the species, then additional data is recorded about the individual for identification (body length, tail length, hind foot length and ear length) as well as other notes. Collection of physical tissue samples is also noted in the data.

Release

Each animal is released back into the environment at the same location they were collected from. Effort is made to ensure that animals are released at least 6 hours prior to sunset so that they have sufficient time to return to their homes and recover before traps are baited again.

Description:

iso_web_1 Monthly mammal trapping, including stable isotope analysis, is carried out at two webs (iso_web) located on either side of McKenzie South Road. Since 2018, vegetation has been sampled on these webs to link relationships between mammal populations and plant communities. Vegetation in the area is dominated by creosote (Larrea tridentata), with other shrubs such as fourwing saltbush (Atriplex canescens), winterfat (Krascheninnikovia lanata) and broom snakeweed (Gutierrezia sarothrae) also abundant, and with black grama (Bouteloua eriopoda) as the dominant grass. The southeastern web (Web 1) is shrub-dominated.
