UCSB SONGS Mitigation Monitoring: Wetland Process Study - Elevations of Spartina in Tidal Creek and Mudflat Habitats in Restored and Natural Wetlands in Southern California
These data describe the elevations of vegetated and unvegetated areas within tidal creek and mudflat habitats at the restored San Dieguito Wetlands (Del Mar, CA), the restored San Elijo Lagoon (Solana Beach, CA), and the natural Tijuana River Estuary (San Diego, CA). Data were collected in November 2022. Transects were established in these habitats at each wetland; the elevation and vegetation type were documented for at least seven points along at least five transects per habitat type.
Phytoplankton growth and microzooplankton grazing rates from CCE LTER Process cruises in the California Current System, 2006 - 2017.
Rates of phytoplankton community growth and microzooplankton grazing on phytoplankton were assessed from chlorophyll a analyses of in situ dilution incubations as described in Landry et al. (2009). For each experiment (Array #), seawater was collected from predawn CTD (~2 a.m. local time) casts at 6-8 depths spanning the upper to lower euphotic zone. For each depth, we prepared a pair of polycarbonate bottles (2.7 L), one with whole seawater (100%), and one with 33% whole seawater (diluted with 0.1-µm filtered seawater) at each depth. Seawater was filtered directly from the Niskin bottles using a peristaltic pump, silicone tubing and an in-line Suporcap filter capsule that had previously been acid washed (10% trace-metal grade HCl followed by Milli-Q and seawater rinses). Dilution treatment bottles received pre-measured volumes of filtered water from the collection depths, and then were gently filled (silicone tubing below the water level) with unscreened water from the Niskin bottles. The filled bottles were tightly capped, placed into net bags and clipped onto attached rings at the depth of collection on a tether line attached to a satellite-tracked surface drifter (WOCE SVP) with a top strobe light, Globalstar telemetry and a 3-m holey-sock drogue centered at 15-m (mixed layer). Incubations were done in situ for 24-h (daily) to get daily averaged rates. In most cases, repeated experiments/deployments were done over the course of 2-5 days, using water collected each morning at the location of the drifter. These back-to-back experiments define experimental “cycles”. The second set of experiments were set up, before recovering the first. Hand recovery of the array, switching of net bags and redeployment was generally completed in 15-20 min. Rate estimates are based on initial and final subsamples (250 ml) taken for fluorometric analyses of Chl a. The samples were immediately filtered onto GF/F filters, and the Chl a extracted with 90% acetone in a dark refrigerator
Root carbon/nitrogen data: Biodiversity II: Effects of Plant Biodiversity on Population and Ecosystem Processes
Biodiversity II (E120) is designed to determine how the number of plant species affects the dynamics of ecological processes at the population, community, and ecosystem levels. By experimentally manipulating the number of species and the kinds of species, the amount of plant growth and the change from year to year, that result can be examined. Plots are large (9m x 9m actively maintained) and well-replicated, allowing responses of plant pathogens, insect herbivores, seed predators, soil parameters, invasive plant species and other variables to also be studied. Plots were seeded in May 1994 to have 1, 2, 4, 8, or 16 species, with roughly 30 replicates of each diversity level. The species composition of each plot was chosen by random draw from a pool of 18 grassland perennials that included four warm-season (C4) grasses, four cool-season (C3) grasses, four legumes, four non-legume forbs, and two woody species. All species occur in monoculture allowing comparison of responses of each species in monoculture to combinations of these same species. The experiment was established in 1994 by the lead investigators David Tilman, Peter Reich, Johannes Knops, and David Wedin. Experiment 120 is similar to Experiment 123, but it uses larger plots to provide a large capacity for long-term subexperiments.

Plant aboveground biomass data: Herbivory by Nitrogen Interactive Effects on Community and Ecosystem Processes and Dynamics
E172 is an herbivory experiment established by Dave Tilman in fall 2004 by enclosing in deer fences three randomly selected plots from the six replicates of each control and each treatment in the N addition E001 experiment in field C. These plots still receive the nutrient treatments prescribed in the Experiment 001 protocols. From 1982-2004 a fence containing all of e001 plots in Field C was designed to exclude deer and all small mammals, including mice, voles and pocket gophers. This fence was removed in Fall of 2004 and individual plots designated for e172 were enclosed in deer fences. The purpose of E001 was to measure how adding nitrogen over a long time would affect the number of species, the type of species present, the amount of annual growth, and the change from year to year in the growth of each species in a plant community which is also relieved of grazing by large and small mammals. There are 8 different levels of nitrogen addition with other nutrients added to ensure that nitrogen remains the limiting nutrient, and a control which receives no nutrients. The plots are in a 6 by 9 grid and are 4 by 4 meters in size with 1 meter aisles between plots. Nitrogen fertilizer (NH4NO3) is applied twice per year, once in early May and once in late June.
