For example, herbivory and temperature, via their effects on primary producers and the metabolic demands of consumers, can also influence macroalgal biomass and productivity, respectively.  Although there is a fair number of studies looking at the interactive effects of herbivores and nutrients in both tropical and temperate regions, there is a lack of studies looking at these effects in tropical or subtropical upwelling regions. The purpose of this study was to measure the effects that herbivores, temperature, and nutrient availability have on standing macroalgal biomass. We manipulated nutrient availability and herbivory in six field experiments during contrasting productivity and thermal regimes (cool-upwelling and warm, non-upwelling season) on a subtidal nearshore rocky reef. \n\nHere, we present the macroalgal biomass raw data (Preburn, Postburn, and Ash-Free Dry Weight) collected in the nearshore shallow subtidal during an October 2022 field experiment.\n\ncdm_data_type = Other\nVARIABLES:\nCage (unitless)\nTreatment (unitless)\nN (unitless)\nAlgae_Type (unitless)\nFoil_cup_weight_g (grams)\nSample_and_foil_cup_weight_g (grams)\nPreburn_weight_calculation_g (grams)\nCeramic_cup_weight_g (grams)\nSample_and_ceramic_cup_weight_g (grams)\nPostburn_weight_calculation_g (grams)\nAFDW_Preburn_minus_Postburn_weight_calculation_g (grams)\n BCO-DMO bcodmo_dataset_904710_v1

log in [Global Seabird Breeding Success] - Annual seabird productivity at breeding colonies around the world from 1964 to 2023 (Stratification Impacts on Seabirds Project) (Global analysis of stratification impacts on seabirds through food resources ) This global dataset on breeding productivity represents a compilation of individual time series from species and sites (seabird breeding colonies) across the world. Each time series was contributed by a Global Seabird Working Group (GSWG) collaborator. It contains the number of offspring produced per nesting female per year, which is a variable measured similarly by researchers. Seabird breeding productivity is typically measured by monitoring individual nest sites through time within each breeding season. Data from multiple females are then averaged to produce estimates of annual productivity for each species at each site, resulting in “species-site” time series. Typically, measurements are made for multiple species at each site, so data are often available for a portion of the full seabird community, including species feeding at different trophic levels and in different parts of the water column. Variance for species-site breeding productivity is estimated as the standard error across years for each time series. Here, there are 202 time series encompassing 87 sites and 73 seabird species.\n\ncdm_data_type = Other\nVARIABLES:\nyear (unitless)\nsite (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nspeciesnum (unitless)\nspecies (unitless)\nScientificName_accepted (unitless)\nAphiaID (unitless)\nLSID (unitless)\nbreeding_success (reproduction_rate)\nn (individuals)\n BCO-DMO bcodmo_dataset_985565_v1

One particularly consequential application of this isotope system is the analysis of dissolved oxygen (O2) in aquatic environments to determine gross oxygen production. This approach assumes that photosynthesis, microbial respiration, and gas exchange are the main drivers of dissolved O2 isotope compositions, and that each process is described by predictable, consistent triple-oxygen isotope effects. However, there currently exists a large disagreement in the literature on the triple-oxygen isotope effect of respiration, which carries major implications for global primary productivity estimates. Recent work has additionally highlighted the ubiquitous production of extracellular reactive oxygen species (ROS) such as superoxide and hydrogen peroxide by microorganisms; this flux maybe responsible for as much as 20% of net oxygen utilization in the ocean. \n\nTo examine the influence of ROS-mediated O2 recycling on the oxygen utilization isotope effect, we measured the triple-oxygen isotope fractionations and mass laws of superoxide dismutase, catalase, and iron-mediated H2O2 degradation. We incorporate these constraints into an oxygen isotope flux model to explore the influence of ROS-mediated oxygen cycling on \"respiration\" isotope effects in previous studies. We find that ROS-mediated oxygen cycling can reconcile the previously reported range of triple-oxygen isotope fractionation factors and that typical marine isotope effects are broadly consistent with independent estimates of superoxide-mediated oxygen loss. These data are described further in the related publication, Sutherland et al., 2022 (doi: 10.1016/j.gca.2022.02.033).\n\ncdm_data_type = Other\nVARIABLES:\nSample (unitless)\nn (unitless)\nd18O_smowslap (permil)\nD17O (permil)\nd17O_smowslap_log (unitless)\nd18O_smowslap_log (unitless)\n https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_923859_v1/index.htmlTable https://osprey.bco-dmo.org/dataset/923859 (external link) https://erddap.bco-dmo.org/erddap/rss/bcodmo_dataset_923859_v1.rss https://erddap.bco-dmo.org/erddap/subscriptions/add.html?datasetID=bcodmo_dataset_923859_v1&showErrors=false&email= BCO-DMO bcodmo_dataset_923859_v1
