| log in | [Latitudinal variation in shell thickness of snails across 20 years] - Latitudinal variation in the shell thickness and tissue mass of Littorina obtusata snails in 1995-1997 and 2017-2018 (Local adaptation and the evolution of plasticity under predator invasion and warming seas: consequences for individuals, populations and communities) | The impact of invasive predators during the early stages of invasion is often variable in space and time. Such variation is expected to initially favor plasticity in prey defenses but fixed defenses as invaders become established. Coincident with the range expansion of an invasive predatory crab in the Gulf of Maine we document rapid changes in shell thickness – a key defense against shell crushing predators – of an intertidal snail. Field experiments, conducted 20 years apart, revealed that temporal shifts in shell thickness were driven by the evolution of increased trait means and erosion of thickness plasticity. The virtual elimination of the trade-off in tissue mass that often accompanies thicker shells is consistent with the evolution of fixed defenses under increasingly certain predation risk. These data describe latitudinal variation in the shell thickness and tissue mass of snail (Littorina obtusata) populations throughout the Gulf of Maine in 1995-1997 and 2017-2018. These data allowed us to evaluate the relationship between spatiotemporal changes in green crab density and spatiotemporal variation in snail shell thickness and tissue mass.\n\ncdm_data_type = Other\nVARIABLES:\nYear (unitless)\nSite_Name (unitless)\nlatitude (degrees_north)\nlongitude (degrees_east)\nShell_Length (millimeters (mm))\nShell_Thickness (millimeters (mm))\nTissue_Mass (milligrams (mg))\nShell_Mass (milligrams (mg))\n | BCO-DMO | bcodmo_dataset_990839_v1 | ||||||||||||

A reduction in pH has been shown to affect mussel growth and shell thickness along the Pacific coast of North America. Mussels, Mytilus californianus, are a foundation species in rocky shore ecosystems and are prey for a number of taxa, including the Channeled Dogwhelk, Nucella canaliculata, which feeds by drilling a hole through the shell of their prey. Previous research has documented geographic variation in N. canaliculata predator drilling phenotype on Mytilus californianus. However, few studies have assessed how variation in mussel shell traits shape the evolution of this co-evolving predator. Thus, we analyzed M. californianus shell thickness over two decades (2000-2001, 2008-2009, and 2019) and across ~1,000 kilometers of coastline to quantify the prey-driven selection landscape. We analyzed mussel shell thickness at 1/3 the length of the mussel shell as this is the most commonly drilled region. Mussel shells from the central Oregon coast were thicker than those from California. This pattern is associated with geographic variation in predator drilling phenotypes. However, the selective landscape appears to be changing, with recent mussel shells being thinner than a decade prior, particularly on the central Oregon coast. This research highlights the importance of studying species interactions across broad spatial and temporal scales.\n\ncdm_data_type = Other\nVARIABLES:\nSite (unitless)\nSite_Code (unitless)\nState (unitless)\nLatitude (degrees_north)\nlongitude (degrees_east)\nDate_Collected (unitless)\nYear_Collected (unitless)\nTime_Period (unitless)\nQuadrat_num (unitless)\nMussel_num (unitless)\nShell_Length (millimeters (mm))\nHeight (millimeters (mm))\n...
