Small mammal trapping (LTER-II)

Study number: 

5

Data set ID: 

210005001

Original investigator: 

John Anderson

Abstract: 

Small mammal live-traps are located on consumer pitfall plots. A grid of 20 traps is located on each consumer plot. Small mammals are trapped daily for a one-week period in the late spring and again in the late summer of each year. Data on species, sex, toe marks, weight, and reproductive condition are taken.

Pitfall trap grids have been installed at three creosotebush sites, three grassland sites, three mesquite sites, and two tarbush sites. Jornada LTER II consumer plots during this period were located at T-WEST, T- EAST, M-RABB (2 grids), M-WELL, G-IBPE (2 grids), G-BASN, C-SAND (2 grids), and C-CALI sites.

Lizard pitfall trap data (LTER-II, LTER-III)

Study number: 

7

Data set ID: 

2100007001

Original investigator: 

David Lightfoot

Data contact: 

Abstract: 

In conjunction with net primary production studies, consumer and faunal studies are conducted at or near NPP sites using pitfall traps. We use live traps, not employing ethylene glycol or other killing/preservative agents, with traps checked once a week at the minimum. Sampling-with-replacement is used with the lizards.

Variables measured include species, sex, recapture status, snout-vent length, total length, weight, and whether tail is broken or whole.
