Comprehensive demographic dataset for Santa Catalina Island, Avalon, CA, US including population statistics, household income, housing units, education levels, employment data, and transportation with year-over-year changes.

Basic morphometric and demographic data was collected for the spiny lobster, Panulirus interruptus, around the west end of Santa Catalina Island from Spring 2003-Spring 2005. This region includes two marine protected areas, many popular sport fishing and diving sites, and a continuous stretch of coastline that is commercially fished. Lobsters were caught using commercial lobster traps without juvenile escape ports and mackerel as bait. Traps were set on the first day at randomly selected sites within a blocked sampling scheme and allowed to sit overnight. On the second day, traps were collected and all lobsters within were evaluated on a number of parameters including (but not limited to) carapace length, weight, gender, and fertility state. Animals were marked with either a uropod punch code, colored cable tie, or floy tag to determine movement patterns and growth rates in the event of recapture.

Allen's Hummingbird comprises two subspecies, one migratory (Selasphorus sasin sasin) and one non-migratory (S. s. sedentarius). The non-migratory subspecies, previously endemic to the California Channel Islands, apparently colonized the California mainland on the Palos Verdes Peninsula some time before 1970, and now breeds throughout coastal southern California. We sequenced and compared populations of mainland non-migratory Allen's Hummingbird to Channel Island populations from Santa Catalina, San Clemente, and Santa Cruz Island. We found no evidence of founder effects on the mainland population. Values of nucleotide diversity on the Channel Islands were lower than those on the mainland. There were low levels of divergence between the Channel Islands and the mainland, although Santa Cruz Island was the most genetically distinct. Ecological niche models showed that rainfall and temperature variables on the Channel Islands are similar in the Los Angeles basin, and predicted continued ex...

The seine has floats along the top line with a lead line of chain along the bottom. Once a school of fish is located, a skiff pulls the seine into the water as the vessel encircles the school with the net. A cable running along the bottom is then pulled in, "pursing" the net closed on the bottom, preventing fish from escaping by swimming downward. The catch is harvested by bringing the net alongside the vessel and brailing the fish aboard. instruments_0_instrument_name=Purse-seine Fishing Gear instruments_0_instrument_nid=675173 instruments_0_supplied_name=Beach seine metadata_source=https://www.bco-dmo.org/api/dataset/713188 param_mapping={'713188': {}} parameter_source=https://www.bco-dmo.org/mapserver/dataset/713188/parameters people_0_affiliation=University of North Carolina - Wilmington people_0_affiliation_acronym=UNC-Wilmington people_0_person_name=J Wilson White people_0_person_nid=516429 people_0_role=Principal Investigator people_0_role_type=originator people_1_affiliation=University of North Carolina - Wilmington people_1_affiliation_acronym=UNC-Wilmington people_1_person_name=Dr Susanne Brander people_1_person_nid=712930 people_1_role=Co-Principal Investigator people_1_role_type=originator people_2_affiliation=University of North Carolina - Wilmington people_2_affiliation_acronym=UNC-Wilmington people_2_person_name=J Wilson White people_2_person_nid=516429 people_2_role=Contact people_2_role_type=related people_3_affiliation=Woods Hole Oceanographic Institution people_3_affiliation_acronym=WHOI BCO-DMO people_3_person_name=Hannah Ake people_3_person_nid=650173 people_3_role=BCO-DMO Data Manager people_3_role_type=related project=Goby size-selection projects_0_acronym=Goby size-selection projects_0_description=Description from NSF award abstract: Many marine fish species change sex during their lifetimes, and many of them are targets of commercial and recreational fishing. The timing of sex change in these animals is often related to body size, so populations typically consist of many small fish of the initial sex (usually female) and few large fish of the other sex (usually male). In nature, smaller fish are at a greater risk of mortality due to predation, but fishermen tend to seek larger fish. Thus fishing that targets larger individuals may skew sex ratios, removing enough of the larger sex to hinder reproduction. However, the extent to which size-selective mortality affects sex-changing fishes is poorly understood. This research will explore the effects of size-selective mortality on the population dynamics of sex-changing species using an integrated set of field experiments and mathematical models. It will provide the first experimental exploration of the sensitivity of different sex-change patterns and reproductive strategies to selective mortality. The results will advance our knowledge of the susceptibility and resilience of sex-changing organisms to different types of size-selective mortality and will reveal how sex-changing species can recover after size-selection ceases, as in populations within marine reserves where fishing is suddenly prohibited. The findings will inform fisheries management policies, which do not currently consider the ability of a species to change sex in setting fisheries regulations. This project will consist of a three-year study of the effects of size-specific mortality on sex-changing fishes. Field experiments will use three closely related rocky-reef fishes that differ in sex-change pattern and are amenable to field manipulation and direct measurement of reproductive output. The species include a protogynous hermaphrodite (a female-to-male sex-change pattern common among harvested species) and two simultaneous hermaphrodites that differ in their ability to switch between male and female. Two types of experiments will be conducted on populations established on replicate patch reefs at Santa Catalina Island, California: (1) sex ratios will be manipulated to determine when the scarcity of males limits population-level reproductive output; and (2) experiments cross-factoring the intensity of mortality with the form of size-selection (i.e., higher mortality of large or small individuals) will test the demographic consequences of size-selective mortality. In concert with the field experiments, size- and sex-structured population models (integral projection models) will be developed for use in three ways: (1) to evaluate how different types of selective mortality should affect population dynamics; (2) to predict outcomes of the field experiments, testing/validating the model and allowing direct prediction of the ecological significance of short-term selection; and (3) to fit to existing survey data for a fourth species, a widely fished, sex-changing fish, inside and outside of marine reserves. Part (3) will evaluate whether and how quickly the mating system and reproductive output of that species (not directly measurable in the field) is recovering inside reserves. This integrated set of field experiments and models will yield novel insight into the effects of size-selective mortality on the population dynamics of sex-changing marine species. projects_0_end_date=2018-02 projects_0_geolocation=Southern California, Santa Catalina Island projects_0_name=Impacts of size-selective mortality on sex-changing fishes projects_0_project_nid=516431 projects_0_start_date=2015-03 sourceUrl=(local files) standard_name_vocabulary=CF Standard Name Table v55 version=1 xml_source=osprey2erddap.update_xml() v1.3

This data file represents a time series of canopy area of giant kelp, Macrocystis pyrifera , and bull kelp, Nereocystis luetkeana , and canopy biomass of giant kelp derived from Landsat 5 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), Landsat 8 Operational Land Imager (OLI), and Landsat 9 Operational Land Imager 2 satellite imagery, along with relevant metadata. The kelp canopy is composed of the portions of fronds and stipes floating on the surface of the water. Canopy area (m) data are given for individual 30 x 30 meter pixels for all coastal areas of Baja California, Mexico, California, Oregon, and the outer coast of Washington (including offshore islands). Biomass data (wet weight, kg) are given for individual 30 x 30 meter pixels in the coastal areas extending from near Ano Nuevo, CA through the southern range limit in Baja California (including offshore islands), representing the range where giant kelp is the dominant canopy forming species. Data were derived from the three Landsat sensors listed above. Observations are made on a 16 day repeat cycle, for each instrument, but the temporal coverage is irregular because of cloud cover, instrument failure, and the mission length of each sensor (TM: 1984 – 2011, ETM+: 1999 – present, OLI: 2013 – present). Estimates of canopy area are derived from the fractional cover of kelp canopy determined from satellite surface reflectance. Estimates of kelp canopy biomass are derived from the relationship between giant kelp fractional cover determined from satellite surface reflectance and empirical measurements of giant kelp canopy biomass in long-term SBC LTER study plots obtained using SCUBA. The different Landsat sensors were calibrated to each other using simulated Landsat data derived from hyperspectral imagery. Missing data due to the ETM+ scan line corrector error were filled using a synchrony-based gap filling method. Data are organized into a single NetCDF file and contain the quarterly area and biomass means for each Landsat pixel across the three sensors. Relevant metadata such as number of Landsat estimates from which the mean was derived, the number of estimates from each sensor, standard error for each quarterly estimate, spatial coordinates, and date are all included in the file.
