“…We then randomly assigned whelks to one of six temperature treatments: 0 °C, 18.5 °C (ambient temperature), 32 °C, 35 °C, 38 °C, and 41 °C. Temperature treatments were chosen based on preliminary experiments and previously collected long-term environmental data in Laguna Beach, CA (Wallingford and Sorte 2019 ; Pandori and Sorte 2021 ). These temperatures represent the gradient of maximum temperatures experienced across Mexacanthina ’s range (Table S1) and include the full range of outcomes for all species (from 0 to 100% survival) to quantify LT 50 (50% survival).…”

Globally, species are undergoing range shifts in response to climate change. However, the potential impacts of climate-driven range shifts are not well understood. In southern California, the predatory whelk Mexacanthina lugubris has undergone a northward range shift of more than 100 km in the past four decades. We traced the history of the whelk’s range shift and assessed potential effects using an integrated approach, consisting of field surveys, as well as feeding and thermotolerance experiments. We found that at sites where Mexacanthina and native species co-occurred, native whelks distributions peaked lower in the intertidal. In laboratory experiments, we found that the presence of Mexacanthina led to reduced growth in native whelks (Acanthinucella spirata). Additionally, the range-shifting whelk was able to tolerate higher temperatures than common native species (A. spirata and Nucella emarginata), suggesting further impacts as a result of climate warming. Many species are likely to undergo range shifts as a coping mechanism for changing climatic conditions. However, communities are unlikely to shift as a whole due to species-specific responses. By studying the impacts of range-shifting species, like Mexacanthina, we can better understand how climate change will alter existing community structure and composition.

“…The rocky intertidal zone is a unique and biologically challenging ecosystem that exists at an interface between terrestrial and marine ecosystems, with unique species of higher plants, algae, and animals that have developed the physiological adaptations to survive a spectrum of physical and biological thresholds such as solar radiation, air and seawater temperatures, ocean waves, desiccation, and predation during periods of low tide [1][2][3][4]. It is a highly productive system with intrinsic ecological and economic value that plays an integral role as a food source for humans as well as in marine food webs and provides habitat and recruitment for a diverse array of marine life including commercially important fish and shellfish [5][6][7].…”

Large areas of the Pacific coast of the Americas remain unstudied regarding their intertidal ecosystems. Given the increasing disturbance related to human impacts on intertidal ecosystems, it is essential to gather census data on the biological composition of poorly studied regions so that a framework for future monitoring and management can be developed. Here, we synthesize the available research on intertidal communities along the Pacific rim to support the goal to fill bioregional gaps in knowledge in three less-studied areas in Southeast Alaska and Peru. A census of taxonomic and functional group hierarchies in these communities should include the use of various measures of alpha and beta diversity to provide a metric of temporal and spatial comparisons. A narrower-scale approach focusing on foundation species that harbor algal and invertebrate communities and serve as buffers against environmental stresses should also be conducted. Conducting a comprehensive census in poorly studied or unstudied areas will contribute to a better understanding of the response to disturbances caused by oil spills, El Niño and marine heatwaves and provide a latitudinal continuum of scientific knowledge about the biodiversity and ecosystem functioning in rocky intertidal systems on a trans-regional scale.

“…In this time of accelerating climate change, there is a crucial need to understand the processes that underly species vulnerability to warming. Environmental temperatures can greatly in uence the rates of biological processes ("thermal sensitivity"), and the local conditions that organisms experience vary widely, creating a mosaic of physiological responses (Pörtner et al 2001;Hochachka and Somero 2002;Angilletta Jr 2009;Huey et al 2012;Pandori and Sorte 2021). Furthermore, organismal responses to climate warming can depend on previous thermal exposure ("thermal history") due to differences in allocation of energy to processes such as thermal tolerance, growth, and metabolism (Calosi et al 2008; Deutsch et al 2015;van Denderen et al 2020).…”

As climate change continues, anticipating species' responses to rising temperatures, requires an understanding of the relationship between metabolic rate and thermal sensitivity, which itself may vary over space and time. We measured metabolic rates of three representative marine invertebrate species (hermit crabs Pagurus hirsutiusculus, periwinkle snails Littorina sitkana, and mussels Mytilus trossulus) and evaluated the relationship between thermal sensitivity (Q 10 ) and thermal history. We tested the hypothesis that thermal history drives thermal sensitivity and quanti ed how this relationship differs over time (short-term to seasonal time scales) and between species. Organisms were collected from tide pools in Sitka, Alaska where we also recorded temperatures to characterize thermal history prior to metabolic rate assays. Using respirometry, we estimated mass-speci c oxygen consumption (MO 2 ) at ambient and increased temperatures for one individual per species per tide pool across three seasons. We evaluated relationships between thermal sensitivity and pool temperatures for time periods ranging from 1 day to 3 months prior to collection. For all species, thermal sensitivity was related to thermal history for the shorter time periods (1 day to 1 week). However, the direction of the relationships and most important thermal parameters (i.e., maximum, mean, or range) differed between species and seasons. We found that on average, P. hirsutiusculus and L. sitkana were more thermally sensitive than M. trossulus. These ndings show that variability in thermal history over small spatial scales in uences individuals' metabolic response to warming and may be indicative of these species' ability to acclimate to future climate change.
