Model of barnacle, its surrounding environment, and map of collection site. a Diagram of a barnacle with cirri retracted and the operculum closed which occurs during periods of emersion. b Diagram of a barnacle with extended cirri during filter feeding. c Model of intertidal stress across the rocky intertidal. d Measurements of tidal height for the month of August 2015 in Damariscotta, ME (NOAA tide station 8416731). e Measurements of maximum daily temperatures across collection sites for sites high temperature sites (High Hot-HH) and low temperature sites (Low Cold-LC) (shown in panel c). Data was collected in the summer of 1994 and published by Schmidt and Rand [23]. The horizontal dashed line indicates the heat coma point. f Range of tidal height for the high and low tides in August 2015 at the Damariscotta River, ME at mornings, afternoons, and nights. g High-resolution temperature profile of HH habitats as a function of tidal range and summertime in Rhode Island. Data was collected in the summer of 2018 and published by Nunez et al. [24, 25]. The temperature axes show temperatures collected every 30 min. The time axis shows times from July to August. The tidal range axis represents the tidal height at the moment of temperature collection (NOAA tide station 8452660, Newport, RI). The oscillations in the tidal range amplitude are produced by the lunar cycle, and the points of maximum thermal stress coincide with the lowest low tides. h Same as G but for LC habitats. i Map of the Damariscotta River in Maine with sampling localities indicated. Barnacles were collected from Hodgson’s Island (HI) and Farmer’s Island (FI). There are four sites: Farmers Island Hot High (FIHH), Farmers Island Low Cold (FILC), Hodgsons Island High Hot (HIHH), and Hodgsons Island Low Cold (HILC). Red dots indicate upper tidal habitats with high sun exposure. Blue dots indicate lower tidal habitats with low sun exposure
