“…Similarly, intertidal mussels experience distinct thermal micro‐environments as they progress through their life stages (Helmuth and Hofmann , De Nesnera , Jurgens and Gaylord ). Mussel larvae experience oceanic conditions, which might be correlated to their thermal tolerance as intertidal recruits (Sorte et al ). As benthic juveniles, mussels can occupy microhabitats with varying amounts of shelter from solar radiation and heat stress (Helmuth and Hofmann , Jurgens and Gaylord ), which can give rise to differences in tolerance across life stages (Vetter et al , Lewis et al , Cripps et al , Alter et al ).…”

“…Our results suggest that unless exposure balances out differences in sensitivity, warming could disproportionately impact younger life stages, making this an even more pronounced bottleneck in population dynamics (O Donnell et al 2009, Findlay et al , Russell et al ). Future studies would ideally investigate the physiological and ecological mechanisms of persistence across life stages, including potential for acclimation, adaptation and migration (Sorte et al , , Suckling et al , , Parker et al , Samani and Bell ), to predict the impacts of climate change on marine invertebrate species.…”

Predicting the effects of climate change on Earth's biota becomes even more challenging when acknowledging that most species have life cycles consisting of multiple stages, each of which may respond differently to extreme environmental conditions. There is currently no clear consensus regarding which stages are most susceptible to increasing environmental stress, or ‘climate extremes’. We used a meta‐analytic approach to quantify variation in responses to environmental stress across multiple life stages of marine invertebrates. We identified 287 experiments in 29 papers which examined the lethal thresholds of multiple life stages (embryo, larva, juvenile and adult) of both holoplanktonic and meroplanktonic marine invertebrates subjected to the same experimental conditions of warming, acidification and hypoxia stress. Most studies considered short acute exposure to stressors. We calculated effect sizes (log response ratio) for each life stage (unpaired analysis) and the difference in effect sizes between stages of each species (paired analysis) included in each experiment. In the unpaired analysis, all significant responses were negative, indicating that warming, acidification and hypoxia tended to increase mortality. Furthermore, embryos, larvae and juveniles were more negatively affected by warming than adults. The paired analysis revealed that, when subjected to the same experimental conditions, younger life stages were more negatively affected by warming than older life stages, specifically among pairings of adults versus juveniles and larvae versus embryos. Although responses to warming are well documented, few studies of the effects of acidification and hypoxia met the criteria for inclusion in our analyses. Our results suggest that while most life stages will be negatively affected by climate change, younger stages of marine invertebrates are more sensitive to extreme heating events.

“…These conditions were chosen because they represent points of 100% expected survival (control) and 100% expected mortality (40°C, based on our preliminary studies), and thermal conditions experienced by individuals in the field (Appendix S4). These methods are analogous to those used by Sorte et al (2018Sorte et al ( , 2019 except that each replicate was run on a different (adjacent) day (i.e., N = 1 for each of 3 d), reducing pseudoreplication. Mussels were placed in 150-mL plastic tubes with a 4cm 2 piece of seawater-soaked chamois cloth at the bottom to prevent desiccation and holes in the cap to prevent oxygen depletion.…”

“…As ocean temperatures increase due to climate change, many marine species are moving their latitudinal range poleward due to temperatures at lower latitudes exceeding the limits of their thermal tolerance (Sunday et al 2012;Pinsky et al 2013;Poloczanska et al 2016;Pecl et al 2017). Poleward range extensions for most sessile or sedentary marine benthic species is facilitated by a dispersive pelagic larval phase (Cowen and Sponaugle 2009) and is largely contingent on ocean currents (Sorte et al 2018), such as western boundary currents (WBC). To date WBCs have played an important role in poleward range shifts of many marine species (Vergés et al 2014).…”

Many marine species are predicted to shift their ranges poleward due to rising ocean temperatures driven by climate change. For benthic marine species with pelagic larval stages, poleward range shifts are often facilitated through pelagic larval transport via western boundary currents (WBC). By surveying pelagic larval distributions within WBCs, species advected poleward of their known distributions can be identified and monitored. Palinurid and scyllarid lobster larvae (phyllosoma) have long pelagic larval durations, providing high potential for poleward advection. We surveyed spatial distribution of phyllosoma within the western-boundary East Australian Current. Due to difficulties morphologically identifying phyllosoma, we tested the utility of molecular identification using cytochrome c oxidase I (COI). From COI sequences of 56 phyllosoma and one postlarva, 65% of sequences consisted of good-quality mitochondrial DNA. Across water types sampled, scyllarid phyllosoma exhibited relatively homogeneous distribution, whereas palinurid phyllosoma exhibited heterogeneous distribution with greatest abundance inside a warm core eddy on the south coast of eastern Australia. Two tropical and one subtropical palinurid species were detected ~75–1800km to the south or south-west of their known species distribution. Our results indicate tropical lobster species are reaching temperate regions, providing these species the opportunity to establish in temperate regions if or when environmental conditions become amenable to settlement.
