SBC LTER: Reef: Community structure and productivity of subtidal turf and foliose algal assemblages at Naples Reef, 2006

This dataset contains abundance, primary production and respiration of macroalgal and turf assemblages at Naples Reef (Santa Barbara County, CA) during 2006. It includes abundance of macroalgae is in terms of biomass (dry weight), and abundance of animals is in numbers of individuals and biomass (ash-free dry weight). Primary production and respiration of the benthos were measured in situ as changes in oxygen in closed chambers that covered 0.1m2 of the bottom. Species richness data are for macroalgae only. Abundance and diversity were measured for the same plots where oxygen measurements were recorded. These data were presented in: <ulink url="http://dx.doi.org/10.3354/meps08131">Miller, R.J., D.

SBC LTER: Santa Cruz Island: Cover of Algae, Invertebrates and Benthic Substrate

These data describe the cover of benthic substrate as determined by a random point contact method. The presence of algae and invertebrate species as well as abiotic substrates are recorded at 80 randomly spaced points along 40 m x 2 m transects. Only one substrate type is recorded at a given point. Percent cover of a given substrate on a transect can be estimated from RPC observations as the fraction of total points at which that substrate was present x 100. These data are part of a long term investigation of temporal patterns in reef community composition. The sampling locations in this dataset include eleven sites along the north shore of Santa Cruz Island. Data collection began in 1982 and this dataset is updated annually.

Annual cycle of organic matter partitioning and its availability to bacteria across the Santa Barbara Channel continental shelf. Aquatic Microbial Ecology, 67:189-209. (DOI:10.3354/ame01586) These data were collected on monthly day cruises from January 2008 to April 2009 on the RV Kelp Fish at five stations across the shelf starting at Mohawk Reef in the nearshore area of the Santa Barbara Channel, California, USA. Data were collected with a SBE19-Plus and rosette sampler. Measurements include standard CTD parameters in 1 m bins (e.g. salinity, temperature, density). At selected depths (1, 5, 10, 20 m), rosette bottle samples were collected for nutrients, pigments, particulate and dissolved organic carbon and nitrogen, and bacterial abundance, community structure and productivity. Phytoplankton abundances (to genus) were obtained from the 5 m sample only.

SBC LTER: Santa Cruz Island: Abundance of Pycnopodia helianthoides

The purpose of the Pycnopodia sampling is to determine the relative abundance of the species Pycnopodia helianthoides at each of 11 sites along the north coast of Santa Cruz Island. P. helianthoides can be an important predator in rocky reef systems and has been thought to contribute to community phase shifts on Santa Cruz Island. Divers conducting fish count in 2003 observed a rapid increase in P. helianthoides individuals and began counting this species during routine surveys.

SBC LTER: Reef: Microsatellite markers for the giant kelp, Macrocystis pyrifera

These data were published as a technical note: Alberto, F., A. C. Whitmer, N. C. Coelho, M. Zippay, E. Varela-Alvarez, P. T. Raimondi, D. C. Reed and E. A. Serrão. 2009. Microsatellite markers for the giant kelp Macroystis pyrifera. Conservation Genetics. 10:1915-1917 doi: 10.1007/s10592-009-9853-9 Abstract: We report the isolation and characterization of 16 microsatellite loci to study the population genetics of the giant kelp, Macrocystis pyrifera. Markers were obtained by screening a genomic library enriched for microsatellite motifs. Of the 37 primer pairs defined, 16 amplified clean polymorphic microsatellites and are described. These loci identified a number of alleles ranging from three to forty (mean= 16.5, and gene diversity ranging from 0.469 to 0.930 (mean= 0.774). The isolation and characterization of these highly polymorphic markers will greatly benefit much needed studies on the molecular ecology of this important macroalga. These data report the isolation and characterization of 16 microsatellite loci to study the population genetics of the giant kelp, Macrocystis pyrifera. 180 samples of blade tissue were collected at Carpinteria Reef, Santa Barbara Channel, CA (USA) in July 2006. Sequence data are available from GenBank. These data were published as a Technical Note in the journal Conservation Genetics in 2009.

SBC LTER: Reef: Feeding relationships for kelp forest species

These data are an assembled food web for all species sampled in the SBC LTER annual kelp forest community surveys. Relationships are taken from literature review on diets and consumption habits of target species, plus searches of theses, grey literature, and student report databases at major west coast libraries. Only feeding observations from studies that showed direct consumption or provided strong evidence of a direct feeding relationship between two taxa were used. Our final food web was revised and verified after consultation with several experts in the field of kelp forest community ecology. See Methods section for complete information on cited literature and contributing experts.

SBC LTER: Santa Cruz Island: Aggregated mean abundance of black surfperch (Embiotoca jacksoni) and prey availability, 1994-2008

These data are the annual mean abundances of three age-classes of black surfperch and their prey at each of 11 sites at Santa Cruz Island, California. Reported values are a) the average number of adult black surfperch, young-of-year black surfperch, and one year-old black surfperch per 40m x 2m transect (for all transects), and b) total food availability (grams per 0.1 m squared) at each site. Food availability includes biomass of caprellid and gammarid amphipods and is calculated from the mean density within Gelidium spp. (for caprellids) and all other foliose or turfing algae (for gammarids). The data also include one year lags for each variable, i.e. the value of the variable at that site in the previous year.

SBC LTER: Nutrient concentrations and algae cover in the Ventura River catchment, California, 2008

Results from these data were reported in: Klose, K., Cooper, S. D., Leydecker, A. D. and Kreitler, J. 2012. Relationships among catchment land use and concentrations of nutrients, algae, and dissolved oxygen in a southern California river. Freshwater Science, 2012, 31(3):908-927 doi: 10.1899/11-155.1 Data not reported here: Chlorophyll-a, physicochemical and land use parameters (e.g., land-use type, water depth, substratum size, % open canopy, and water velocity) were used in the paper's analysis and so were also collected, but are not reported here. Nutrient diffusing substrata (NDS) were deployed at 12 sites to assess the nutrient(s) limiting algal growth; these data are also not reported here. Macroalgal cover and stream nutrients are reported during spring and summer 2008 at 15 stream and estuarine sites in the Ventura River catchment in southern California, USA. Data were collected within a mosaic of undeveloped, agricultural, and urban areas to examine relationships among land use, nutrients, algae, and dissolved oxygen (see paper, linked below). This dataset reports major dissolved nutrients (phosphate, nitrate, ammonium) and total dissolved nitrogen and phosphorus, from May to September 2008, and percent cover of macroalgae (benthic and floating) at the same sites at the beginning and end of this period.

SBC LTER: Reef: Geospatial structure of microsatellite markers for the giant kelp, Macrocystis pyrifera, Santa Barbara CA, 2009

Data package includes data and R code for the examination of geospatial genetic structure (SGS) and simulation of inbreeding in giant kelp (Macrocystis pyrifera) from the Santa Barbara Channel, California. Data are reported for microsatellite markers from individual giant kelp plants from Carpinteria Reef, Mohawk Reef and Goleta Bay, collected during September 2009. Relative X and Y coordinates (meters) were recorded for each specimen sampled. R code consists of two scripts, a) to calculate mean number of alleles per locus, and observed and expected heterozygosity, and b) to simulate self-fertilization and sibling/cousin relationships. These data were presented in: Johansson, Mattias L, Raimondi, Peter T, Reed, Daniel C, Coelho, Nelson C, Serrão, Ester A, Alberto, Filipe A. In press.
