“…It was then substituted by the more resistant Pacific cupped oyster sister species C. gigas with distributions in Asia overlapping those of native C. angulata (Grizel and Héral, 1991). Haliotis and Crassostrea in North America have similar histories of overfishing and stock depletion across the 19 and 20th centuries (Braje et al, 2009(Braje et al, , 2016Rick et al, 2016). As for the Manila clam R. philippinarum, it has a natural distribution on the West coast of the Pacific from the Philippines to Russia.…”

“…Conservation efforts are focused in restoring and protecting abalones in the Pacific: shore picking of H. rufescens is allowed only under strict rules, and fishing of H. cracherodii (commercial or recreational) have been suspended (Haas et al, 2019). Management and conservation plans would greatly benefit from shell aDNA analyses that could help better understand the dynamics of genomic diversity and distribution for the two species, the effects of exploitation, infection and predator recovery, and complement archeological studies aimed at helping in abalone restoration (Braje et al, 2009(Braje et al, , 2016Hofman et al, 2015).…”

The shells of marine mollusks represent promising metagenomic archives of the past, adding to bones, teeth, hairs, and environmental samples most commonly examined in ancient DNA research. Seminal work has established that DNA recovery from marine mollusk shells depends on their microstructure, preservation and disease state, and that authentic ancient DNA could be retrieved from specimens as old as 7,000 years. Here, we significantly push the temporal limit for shell DNA recovery to ≥100,000 years with the successful genetic characterization of one Portlandia arctica and one Mytilus mussel sample collected within a dated permafrost layer from the Taimyr Peninsula, Russia. We expand the analysis of ancient DNA in carbonate shells to a larger number of genera (Arctica, Cernuella, Crassostrea, Dreissena, Haliotis, Lymnaea, Margaritifera, Pecten, Ruditapes, Venerupis) from marine, freshwater and terrestrial environments. We demonstrate that DNA from ancient shells can provide sufficient resolution for taxonomic, phylogenetic and/or population assignment. Our results confirm mollusk shells as long-term DNA reservoirs, opening new avenues for the investigation of environmental changes, commercial species management, biological invasion, and extinction. This is especially timely in light of modern threats to biodiversity and ecosystems.

“…For East Pacific green turtle populations that collapsed from overfishing, reconstructing three centuries of fisheries data identified the timeframe most likely to represent appropriate conservation targets (Early-Capistran et al, 2018). Finally, knowledge of historically higher black abalone distribution and abundance assisted with restoration site selection (Braje, Rick, Erlandson, Rogers-Bennett, & Catton, 2016).…”

Understanding changes over historical timescales is essential to gauge conservation status of a species. Modern ecological data typically neglect past magnitudes of change, which fortunately can be evaluated by bridging disparate knowledge sources. We synthesized zooarchaeological, historical, traditional, and western science knowledge to document changes in relative abundance of key species in Canada's northern abalone social–ecological system (SES) from the Holocene to present. Integrated models fit to traditional and western science data revealed 3.7% annual population decline from 1940s to 2010s for large abalone, although traditional knowledge density estimates were 9.5× higher than those derived from western science. Abalone are presently scarce compared to the mid‐1900s, but more abundant than before the early 1800s, calling their endangered status into question. Linking multiple knowledge sources can build SES understanding, facilitate power sharing, and support ecologically sustainable and socially just conservation outcomes.

“…Archeologists and other historical scientists have taken up this call as part of a marine historical ecology research agenda, simply defined as the integration of marine ecology and history (Rick & Lockwood, 2012). One especially fruitful avenue of marine historical ecology studies has focused on the effects of humans on nearshore shellfish communities, incorporating archeological, paleoecological, and historical data into modern management practices and restoration strategies (e.g., Braje, Rick, Erlandson, Rogers-Bennett, & Catton, 2016;Finney, Gregory-Eaves, Douglas, & Smol, 2002;Lotze et al, 2006;Rick et al, 2016;Rogers-Bennett, Haaker, Huff, & Dayton, 2002).…”

For over 10,000 years, black abalone ( Haliotis cracherodii ) were an important resource in southern California, first for coastal Native Americans, then beginning in the nineteenth century, as one of the state's first commercial shellfisheries. By 1993, after years of heavy fishing, rising sea surface temperatures (SST), and the spread of withering syndrome (WS), black abalone populations declined dramatically, resulting in the closure of the Alta California fishery. After nearly 25 years of management and recovery efforts, black abalone are showing signs of ecological rebound along some Channel Island shorelines. These include the presence of juvenile abalone and increasing densities, largely from data collected by Channel Islands National Park (CINP) monitoring efforts that began in 1985. In an effort to apply deeper historical perspectives to modern fisheries management and restoration, we analyzed black abalone size data from San Miguel Island at prehistoric and historical archeological sites spanning the last 10,000 years and compared these populations to those described by CINP biologists between 1985 and 2013. We found a statistically significant relationship between SST and black abalone size distributions during the ancient record, along with dramatic shifts in population size structure toward larger individuals between the nineteenth century and modern periods. A pattern of larger mean black abalone sizes was identified during warm SSTs, when compared against intervals of cooler SSTs. Synthesis and applications. Our study provides a deep historical perspective of abalone population size distributions, patterns within these distributions through time, and parallels to modern abalone populations. Our results may help managers determine whether the current (and future) size and age structure of intertidal black abalone populations around the northern Channel Islands are “natural” and healthy, measured against the 10,000 year history of black abalone fishing in southern California.
