This species was formerly known as Crassostrea gigas, and some debate continues about its nomenclature [22], but we support recent arguments in favor of the use of M. This underscores the need for an updated range-wide synthesis of the population status of both native O. The species differ in many regards. Gigas is larger (Fig 1), grows faster, and free-spawns eggs, while O. Lurida releases larvae after a short brooding period, and typically occurs lower in the intertidal zone [15, 19, 26].
A food fad that lives on
Conserving foundation species requires knowledge about where they currently exist and where they once existed. Such spatiotemporal information allows conservation practitioners to more effectively target their efforts, for example, by protecting the most extensive remaining populations or restoring species to areas that have experienced declines. Thus, pro-actively identifying and conserving foundation species is likely the most economical and effective means to sustain their populations and the ecosystem services that they provide [9]. Information on past distribution and abundance usually resides in many different records that can be challenging to integrate. Thorough quantitative characterizations often occur well after declines have begun, either because declines began so long ago and/or because little attention was paid initially to common-place, ubiquitous species.

We used estuary as replicate for this analysis. We also plotted indices vs. latitude using estuary as replicate. As the relationship was distinctly non-linear, we used local polynomial regression fitting for visualization.
Species differences
It was previously absent at these latitudes where it is now present. The species also occurs currently further south beyond the scope of our study (J. Lorda, pers. comm.), which focused within the range of O. To evaluate differences in the indices between O. Gigas post-2000, we calculated the average Distribution and Abundance Index per estuary and compared these between species using a paired Wilcoxon test with statistics and graphing as described above. We used only estuaries that had at least three records for each species, which yielded 39 for the Distribution Index and 19 for the Abundance Index.
The index is shown for estuaries if at least three records were available for the time period. Estuaries were included in this table only if at least one species had three records for both periods for at least one index. Blank cells indicate that fewer than three records were available. The change in the index at each estuary is shown if data are available for both periods. Lurida showed a significant decrease in Abundance Index over time (Fig 7). We found that 82% of estuaries had declines while only 12% had increases in abundance.
Fill a medium bowl with ice and place a smaller bowl into the ice. Shuck the oysters, placing them into the small bowl so that the oysters are kept chilled. With the repeal of Prohibition in 1933, Levy announced he would once again use wine in cooking at both his restaurants. Newspapers later reported that squabs simmered in wine, what we’d now call his signature dish, became famous from coast to coast. Five years later, with his downtown chophouse well established, he was back in Hollywood with Al Levy’s Tavern, which a contemporary described as “a Hollywood version of an English inn.” It also featured a separate kitchen for kosher food. It was one of the three leading celebrity hangouts around the fabled corner of Vine Street and Hollywood Boulevard, along with Sardi’s and the Brown Derby.
Gigas is plotted against the log10 of the area of the estuary and fitted with linear regression; the Kendall rank correlation is shown. Each point represents a single estuary in all graphs. Gigas, there was a marginally significant increase in Distribution Index over time (Fig 7).
The on-line database we created can be updated in the future as more records are located. Gigas, we attempted to obtain all records within the O. Lurida range and to the north of it so that we could identify the northern range limit on this coast. On the southern end, we stopped searches and data entry at the southern range limit of O. Lurida, recognizing that aquaculture and possibly wild populations of M. Gigas extend considerably farther south.
To evaluate differences in size and isolation of networks, we also used a paired Wilcoxon test with networks in the same areas compared to each other. To examine relationships among the indices within and between species, we plotted them against each other and calculated the Pearson correlation coefficient. To evaluate temporal changes, we compared pre-2000 to post-2000 indices because there was a natural break in the number of records and because this millennial break-point is a conventional temporal boundary to consider.
Information on current distribution and abundance can also be challenging to integrate across the large geographic scales that correspond to the ranges of many coastal foundation species. The distribution of the two species is similar and the northern range limits are at similar latitudes, although M. Gigas was observed slightly farther north (Fig 3). Both species are limited almost entirely to bays and estuaries, but there are a few records of O. Lurida on the open coast of Southern California. Lurida is documented as currently present in 52 estuaries while M.
We created a separate, merged layer of estuaries (Washington, Oregon, and California, U.S. and Baja California, Mexico) and physical ecosections (British Columbia, Canada) also using data in Table C in S1 File. We performed basic spatial analyses (e.g., size, centroid) on estuaries and ecosections. We performed a Spatial Join of all oyster records to country, state/province, and estuary/ecosection. The analysis was conducted separately for each oyster species. We conclude that partnerships between community scientists and monitoring organizations can yield rich datasets [77].
Overall, 70% of estuaries with data for both periods had increases while 20% had decreases. Five of the estuaries had changes in the Distribution Index of ≥0.5; four were increases (three estuaries in Washington and one in Southern California) while one was a decrease (in Oregon) (Fig 8). Changes in the Abundance Index over time could not be calculated because of the near-complete lack of abundance data pre-2000.

That year there were 30 times as many people living in Los Angeles as when he’d arrived half a century before. The oyster cocktail king had fed four generations of them. This was no lunch counter -- Al Levy’s Cafe was big enough to seat 1% of the city’s population at the time. The Times called it “one of the West’s swellest cafes.” A former director of the Chicago Symphony directed the house orchestra. When Republican reformer Hiram Johnson launched his gubernatorial campaign in 1910, it was at Al Levy’s Cafe. For tourists, having an oyster cocktail became one of the things to do in Los Angeles, and they spread the craze around the country.
There’s just something about a restaurant with a long history that has stood the test of time that makes us appreciate it here in Washington, especially after all the industry struggles in recent years. And when said restaurant happens to have delicious food, it’s even more appealing. Spoon the chilled sauce over the shucked oysters and mix. Divide the sauced oysters among 6 small bowls or glass cups. In 1941 Al Levy was buried in Forest Lawn Cemetery with a Jewish service at the Wee Kirk o’ the Heather.
