Climate hindcasts: exploring the disjunct distribution of Diopatra biscayensis

Abstract

Invertebrate Biology 135(4): 345-356.

Annual temperature variation as a time machine to understand the effects of long‐term climate change on a poleward range shift

“…For example, models from Wethey et al. (); Wethey, Woodin, Berke, and Dubois () predicted climate‐mediated interior range fragmentation for the polychaetes Diopatra spp. and Arenicola marina , and to a lesser extent for the barnacles S. balanoides and Chthamalus spp.…”

The impact of aquaculture on the genetics and distribution of the onuphid annelid Diopatra biscayensis

“…(2.4°W-1.6°W, 48.6°N-48.7°N) are more than 450 km away from other known localities and are associated with extensive imports of aquaculture material (Goulletquer & Le Moine, 2002;Woodin et al, 2014). Further, the 450 km of coastline between disjunct localities, including the Brittany Peninsula, was shown in previous simulations to not be hospitable to Diopatra until likely the late 21st century due to cold water temperatures (Wethey et al, 2016).…”

“…Large species of Diopatra have present-day phylogeographic patterns that are particularly difficult to interpret as they have been moved for sale as fishing bait, in association with shellfish aquaculture, and have undergone natural shifts in ranges partly in response to climate change (Arias et al, 2016;Berke et al, 2010;Saito et al, 2014;van der Have et al, 2015;Wethey et al, 2016;Woodin et al, 2014).…”

“…Two conspicuous species of Diopatra occur along the western coastlines of France and Spain in intertidal to subtidal habitats where they build tubes decorated with debris such as shell and algal fragments. Whereas D. neapolitana occurs within Spanish waters and along the southern French coast, D. biscayensis extends from San Vicente de la Barquera, Spain (43.3833° N, 04.3833° W), to the Normanno-Breton Gulf, near Champeaux, France (48.7327° N, 1.5521° W), on the English Channel (Arias & Paxton, 2015;Wethey et al, 2016;Woodin et al, 2014; Figure 1). The more or less contiguous distribution of D. biscayensis has a northern limit at La Trinité-sur-Mer, France, within the Bay of Biscay (47.5830°N, 3.0242°W), but approximately 450 km of coastline further into the English Channel and around the tip of Brittany, there are a number of localities hosting D. biscayensis within the Normanno-Breton Gulf.…”

Ecological and environmental drivers of blue crab population dynamics across scales

“…2.3a). The analysis assessing larval survival probability using mean August and September water temperatures was conducted using both the direct (uncorrected) model output and the model output that was bias corrected at each latitude by subtracting the mean difference between the CMIP5 and OISST data during the period of overlap (2000-2015) following the methods in Wethey et al (2016).…”
