General Information
Data Package:
Local Identifier:edi.646.1
Title:Abundance and species composition of benthic heterobranch molluscs from the Santa Barbara Channel mainland
Alternate Identifier:DOI PLACE HOLDER
Abstract:

These data are counts of heterobranch molluscs (sea slugs and allies) from rocky intertidal sites on the mainland coast of the Santa Barbara Channel. Data collection began in 2002 and 2008 at Naples Point and Tar Pits Reef, respectively, and is ongoing. Data include counts of individuals of 68 total species, presence/absence of their egg masses, and search time (as observer hours) for each sampling trip.

Methods and protocols used in the collection of this data package
Description:

Heterobranchs were identified and counted during timed surveys focused on tide pools and the undersides of boulders, cobbles and ledges in the low intertidal zone at two primary sites, Naples Point on the Gaviota coast and Tar Pits Reef in Carpinteria. As of June 2020, 68 total species have been recorded, 55 from Naples Point, and 52 from Tar Pits Reef. Images of most species from each site have been posted on the website iNaturalist, and voucher specimens of approximately half the species have been deposited in the California Academy of Sciences. For analyses of temporal trends in the composition of local assemblages of heterobranchs with regional oceanographic conditions such as the EI Nino Southern Oscillation, decadal oscillations, and longer term climate change, we assigned each species to a geographic range group as follows. Northern species as those ranging south only to San Diego or northern Baja California and northward to at least central Oregon. Southern species as those ranging south to at least Baja California Sur and northward usually only to southern, central, or northern California. Widespread species as those ranging from at least as far south as Baja California Sur and at least as far north as Washington. By this classification northern species are primarily from the Oregonian Biogeographic Province, and southern species are mainly from the Panamic or Californian Provinces.

Abstract:

The Santa Barbara Channel Marine Biodiversity Observation Network (SBC MBON) is designed to provide a complete picture of marine biodiversity in the region. SBC MBON is developing a widely applicable research model that integrates new information with existing data to improve current research and monitoring programs and provide greater insight into marine biodiversity.

Funding:

MBON is funded by National Aeronautics and Space Administration (NASA), Bureau of Ocean Energy Management (BOEM), and National Oceanic and Atmospheric Administration (NOAA).
