Elevational gradient in ant diversity in the Coweeta Hydrologic Laboratory in 2005
This study will examine spatial patterns of ant diversity, body size, and community composition along the elevational gradient at Coweeta. The data will be part of a larger study that will examine several gradients in the US and abroad to assess whether there are general mechanisms that shape these diversity gradients. Patterns of ant species diversity are well documented and yet the mechanisms promoting species coexistence among communities are often elusive. Two emerging hypotheses that account for coexistence in ant communities are the discovery-dominance tradeoff and the dominance-thermal tolerance tradeoff. Here we used behavioural assays and community-level sampling from ant assemblages in the southern Appalachians, USA to test for the discovery-dominance and dominance-thermal tolerance tradeoffs. The investigators involved were Nathan Sanders, Robert Dunn, JP Lessard, and Melissa Geraghty.
Seasonal leaf litter mass (2000 - 2010) for the Functional Diversity project, Coweeta Hydrologic Laboratory, Otto, North Carolina
The importance of the herbaceous layer in regulating ecosystem processes in deciduous forests is generally unknown. We use a manipulative study in a rich, mesophytic cove forest in the southern Appalachians to test the following hypotheses: (i) the herbaceous functional group (HFG) in mesophytic coves accelerates carbon and nutrient cycling, (ii) high litter quality input and rapid nutrient turnover associated with HFG will have a positive effect on overstory tree growth, and (iii) the HFG regulates tree regeneration with negative effects on seedling establishment due to competition for resources. We established treatment plots in a mesic, cove-hardwoods forest and removed the herbaceous flora (HR, removed twice per year) or added herbaceous organic material (OMA, once per year) for comparison to a no removal (NR) reference for a total of 14 years. The OMA treatment stimulated soil N-mineralization and increased litterfall mass and N content. OMA N-mineralization rates were more than two times greater than both the NR and HR treatments; however, we did not detect significant differences in soil CO2 efflux among treatments. Higher overstory litterfall mass and N in the OMA treatment plots indicated that overstory trees were benefiting from the enhanced soil N-mineralization. Higher overstory leaf mass and N suggests an important linkage between HR and aboveground net primary production even though this did not translate into greater tree basal area increment. We found an increase in regeneration of all tree species with HFG removal, and the response was particularly evident for Acer rubrum seedlings.

Microbial biomass at the Coweeta Hydrologic Laboratory in 1994
All of the data originated in the riparian watershed (WS 55) at Coweeta. Thus far, all soil data occurred in 1994 - ie. before the rhododendron removal. The summary C and N files are saved by date (year, month,and day). Within each file are data for Microbial carbon and nitrogen. The sample names (ex. C1-1, 0-5) indicate control plot, 1 meter distance from the stream, sample number 1, at the 0-5 cm soil depth, and so on. T would indicate treatment plot and 5-10 indicates the 5-10 cm soil depth. Within each plot (C and T), we established three transects, 10 meters in length, at 1, 5, and 15 meter distances upslope from a stream. Along each transect, 4 samples were collected and each sample consisted of two bulked soil cores, separated by depth (0-5 cm and 5-10 cm). All sampling dates were in 1994, beginning in March. Sample dates were selected to correspond with seasonal changes and occurred March 25, June 16, August 16, November 1, and December 16. Microbial C data is listed as microgram C per gram dry weight soil, followed by an average of C (measured by distance from the stream) and standard deviation corresponding to that average. ND listed in the Project indicates that the sample needs to be reanalyzed or was missing. The december Project needs more work, but I have included it anyway. Microbial nitrogen is listed as microgram of total persulfate N per gram dry weight soil. This is again followed by an average N value by distance from the stream and depth of the soil and the corresponding standard deviation.
Geomorphology of Ball Creek and Coweeta Creek in 1989
Measurements of geomorphological parameters were made every 10m along the entire length of Ball Creek / Coweeta Creek down to the Forest Service boundary. Measurements started 300m from the headwaters because most of the first 300m are underground.
Fish collections at Coweeta LTER 100 m stream sites from 1991 to 1998
We monitored fish populations at three sites in a southern Appalachian stream system during a 40-month study. Electro-fishing was performed biannually in spring (May) and late summer(Aug-Oct), to assess stream fish populations, production and recruitment in the LTER 100m sites: Coweeta Creek, Lower Ball Creek, and Upper Ball Creek. These data will be used with habitat availability estimates recorded during the same time periods to see if fish assemblages structure and production of species differ along the gradient in concordance with changing abundance of patch types.
Benthic organic matter (BOM) standing crops along the Ball Creek / Coweeta Creek elevational gradient at the Coweeta Hydrologic Laboratory from 1991 to 1992
We investigated how benthic organic matter (BOM) standing CR varied over space and time in the context of an elevational stream-size gradient. Samples were collected with a stratified random procedure to also study how BOM varied with respect to the major habitat patches within the stream. Habitat patch include cobble-riffle, sandy-reach, and rock. Benthic organic matter was collected efuarterly from streams draining a 9-yr-old clearcut, an 18-yr-old "old-field", a 25-yr-old successional forest, and two reference watersheds at Coweeta Hydrologic Laboratory in the Appalachian Mountains of North Carolina, USA. Samples were separated into large benthic organic matter (LBOM >1 mm) and fine benthic organic matter (FBOM <1 mm). An additional survey of large (>5 cm diam.) and small (1-5 cm diam.) wood was conducted. This study was conducted from 1991 to 1992.
Age, growth and reproduction of mottled sculpin (cottus bairdi) in the Coweeta creek drainage from 1993 to 1998
We quantified: (1) growth rate, (2) length-mass relationships, (3) size- and age-specific fecundity, (4) egg sizefrequencies, and (5) size- and age-specific egg diameter relationships for reproductively active female C. bairdi from one of the southern-most extant populations of this species (Coweeta Creek drainage, North Carolina). Gravid females were collected during February and March in 1993–1995, and 1998.Cottus bairdi were collected from Shope Fork and Ball Creek in early spring prior to spawning. We are determining age and length specific fecundities from analysis of whole ovaries. We are also investigating whether are age or length specific differences exist in egg size. We are determining sex specific growth rates back-calculation of age at length from otolith analysis.
