“…This cohabited ecotone is well described. recently documented this phenomenon on Georges Bank (see also Powell et al, 2019). The finding of smaller surfclams offshore in this survey east of Nantucket is consistent with the expectation of recent colonization in deeper water.…”

“…The interaction of species thrown together by climate change, transiently as ranges shift at differing rates, is little understood. The Atlantic surfclam and the ocean quahog co-occur over an extensive boundary as surfclams invade ocean quahog habitat (Powell et al, 2019). What interaction occurs remains unknown, but both species are routinely found together along the invasion front, indicating that competitive exclusion is not occurring, at least on a time scale amenable to survey monitoring.…”

“…These two species occupy the cold temperate (Virginian Province—Hale, ) and boreal (Acadian Province—Hale, ) sides of the north‐temperate advancing temperature boundary. As the surfclam responds more rapidly to warming temperatures with an across shelf shift in range (Hofmann et al, ; Timbs, Powell, & Mann, ), the two species presently occupy an ecotone extending along much of the mid‐Atlantic region (Powell, Ewing, & Kuykendall, ). The dynamics of this geographically extensive ecotone remain unstudied, save for its documentation.…”

The intermingling of benthic macroinvertebrate communities during a period of shifting range: The “East of Nantucket” Atlantic Surfclam Survey and the existence of transient multiple stable states

A survey of the region eastward of Nantucket provided an opportunity to examine the cold temperate–boreal boundary along the high‐energy Great South Channel. Here described are the benthic macroinvertebrate community types encountered, with a focus on the influence of climate change on the range boundaries of the benthic biomass dominants and the potential existence of transient multiple stable states. The survey identified three primary community types. The shallowest sites were occupied by a surfclam‐dominated community, comprising an abundance of large (≥150 mm) surfclams, and a few common attached epibiota primarily attached to exposed surfclam shell. Two communities exist at intermediate depths, one dominated by submarket and small market‐size surfclams (<150 mm) and the other, created by mussel mats and their attendant epibiota, crabs, sea urchins, and other mobile epifauna. Mussels are a foundational species, establishing a hard‐bottom terrain conducive to these other denizens in soft‐bottom habitat. Cobbles were nearly ubiquitous, rocks were routinely recovered, and boulders were encountered occasionally. Slow growing attached epibionts were exceedingly rare and mobile epifauna were not obviously associated with these large sedimentary particles; nor were the surfclam or mussel communities. The frequency of barnacle scars suggests sediment scour under the high‐flow regime characteristic of the surveyed region, which voids the habitat potential of these sedimentary particles. The abundance of surfclam shell indicates that surfclams have inhabited the shoaler depths for an extended time; limited shell at deeper sites supports the inference from the absence of large animals that these sites are relatively newly colonized and represent further evidence of an offshore shift in range brought on by increasing bottom water temperatures. The dichotomous nature of the two primary community types at mid‐depths suggests that these two communities represent multiple stable states brought on by the interaction of an invading cold temperate species with the receding boreal fauna resulting in a transient intermingling of species, which, however, structure the habitat into exclusionary stable states rather than overlapping in a co‐occurrence ecotone.

“…CPB has the potential to provide data that are salient—relevant to the needs of decision makers and timely (Cash et al 2003)—through its unique long-term perspective (e.g., Jackson et al 2001; Volety et al 2009; Rick and Lockwood 2013; Wingard and Lorenz 2014; Dietl et al 2015; Durham and Dietl 2015; Smith et al 2018; Leonard-Pingel et al 2019; Powell et al 2020). To date, the contributions of marine CPB have mainly consisted of providing geohistorical baselines of past species’ composition and abundance in communities (Kowalewski et al 2000; Jackson et al 2001; Dietl and Flessa 2011, 2017; Louys et al 2012; Rick and Lockwood 2013; Dietl et al 2015; Tyler and Schneider 2018).…”

“…In the rapidly changing Anthropocene world, however, change is the new norm (Halpern et al 2008; Stein et al 2014). As species move in response to, and because of, human actions and multiple environmental stressors (e.g., Aronson et al 2007; Greenstein and Pandolfi 2008; Sunday et al 2012; Pinsky et al 2013; Smith and Dietl 2016; Morley et al 2018; Saupe et al 2019; Powell et al 2020), the underlying assumption of environmental (i.e., climatic) stability inherent to Kidwell's approach becomes increasingly untenable for establishing restoration targets (Wolkovich et al 2014; Corlett 2015; Kopf et al 2015).…”

Increasing the salience of marine live–dead data in the Anthropocene

As the climate changes and ecosystems shift toward novel combinations of species, the methods and metrics of conservation science are becoming less species-centric. To meet this growing need, marine conservation paleobiologists stand to benefit from the addition of new, taxon-free benthic indices to the live–dead analysis tool kit. These indices, which were developed to provide actionable, policy-specific data, can be applied to the readily preservable component of benthic communities (e.g., mollusks) to assess the ecological quality status of the entire community. Because these indices are taxon-free, they remain applicable even as the climate changes and novel communities develop—making them a potentially valuable complement to traditionally applied approaches for live–dead analysis, which tend to focus on maintaining specific combinations of species under relatively stable environmental conditions. Integrating geohistorical data with these established indices has potential to increase the salience of the live–dead approach in the eyes of resource managers and other stakeholders.

Interactive Effects of Climate Change‐Induced Range Shifts and Wind Energy Development on Future Economic Conditions of the Atlantic Surfclam Fishery

Rising water temperatures along the northeastern U.S. continental shelf have resulted in an offshore range shift of the Atlantic surfclam Spisula solidissima to waters still occupied by ocean quahogs Arctica islandica. Fishers presently are prohibited from landing both Atlantic surfclams and ocean quahogs in the same catch, thus limiting fishing to locations where the target species can be sorted on deck. Wind energy development on and around the fishing grounds will further restrict the fishery. A spatially explicit model of the Atlantic surfclam fishery (Spatially Explicit Fishery
