| Abstract: |
| |
Increases in soil moisture from snow packs may influence distribution and abundances
of soil invertebrates. In this study, two snow fences were erected in Lake Fryxell and Lake Bonney
basins to trap snow and examine the effects of increased snow pack on soil physical, chemical and
biological properties.

| Notes about the attribute table |
Since the attribute table for this dataset is very large, the user must construct the actual column
name. The FIRST letter represents the species, and the following letters represent the life stage/sex/sum type. The nermatode
species codes are:
S: Scottnema lindsayae
E: Eudorylaimus spp.
P: Plectus spp.
For example, in the attribute table, "(code)ML" has the description "The total number of living male (species) adult nematodes extracted
from the soil sample in number of organisms per kg soil oven dry weight equivalent. In this case, a column name
called "SML" would be "The total number of living male Scottnema lindsayae adult nematodes..."
BD refers to values below detection.
|
| Sample ID / TREATMENT Codes |
In the attribute table, the treatment is the manipulation for a given plot from where the soil was collected. The treatments are:
(W) Western side of snow fence, (E) Eastern side of snow fence, 1-6 (the first number of the sample code) block, 3-12
(second number of the sample code) distance from snow fence (ft).

| Preserved Samples |
Preserved nematode samples are stored in the NREL Preserved Nematode Collection in room 226, College of Natural Resources, Colorado State University. Soils are stored in the Environmental Measurements Laboratory at Dartmouth College.
