Abstract: 

*We designed a study to examine the long-term spatial and temporal patterns of mass loss, changes in nitrogen content and chemical composition during decomposition of roots in a desert watershed. Because nitrogen availability has been hypothesized to affect decomposition rates of buried litter in deserts, we studied decomposition of roots along a transect on a desert watershed that had been fertilized with ammonium nitrate and compared these results with the decomposition of roots along a transect that had not been fertilized.

Abstract: 

Rabbit pellets were collected from 24 5x5m plots at approximately 1 month intervals. Dry weight by date and plot was recorded. Pellets were subsampled and analyzed for Total N. Plots are located along LTER-1 Control and Treatment transects in creosotebush (around station C62 and T61) and upper basin slope. (See site description.) Plots are located along LTER-1 Control and Treatment transects in creosotebush (around station C62 and T61) and upper basin slope. (See site description.)

Abstract: 

Leaf weight-per-unit area of Larrea tridentata from creosote zone on LTER-I Control and Treatment transects was calculated. Litter used was collected from 4 litter baskets placed under each of 10 bushes on Control Transect and also the Treatment transect. Litter was from month of October litterfall. Thirty whole leaves were picked from each bush, dry weight obtained, soaked in H20 to soften, flattened, and run through area meter.

Abstract: 

Rabbit browse (clippings) were collected from 24 5x5m plots at approximately 1 month intervals. Dry weight by date and plot was recorded. Plant material collected was subsampled and analyzed for Total N. Plots are located along LTER-I Control and Treatment transects in creosotebush (around station C62 and T61) and upper basin slope (around station C48 and T46). (See site description.)

Abstract: 

Rabbit browsed (=clipped) plant material found lying on the ground was collected from 24 5x5m plots at approximately 1 month intervals. Dry weight by species, date and plot was recorded. Material was subsampled and analyzed for Total N. Plots are located along LTER-1 Control and Treatment transects in creosotebush (around station C62 and T61) and upper basin slope. See site description.
