“…In wave-exposed shores, wave splash is the primary threat faced by the gastropods clinging to rocks. Thus, thin shells and larger apertures, which allow a larger foot area, tend to be advantageous, because these characters can reduce the risk of dislodgement by waves (Trussell et al ., 1993; Forrester et al ., 2016). In contrast, in the case of protected shores with reduced wave splash, i.e.…”

Molluscan shells showing phenotypic variations are ideal models for studying evolution and plasticity. In north-eastern Asia, genetic and morphological diversity of the gastropod, Monodonta labio, were assumed to be influenced by both palaeoclimatic changes and current ecological factors. In this study, we examined spatial variations in shell shape of M. labio using general measurement and geometric morphometric analysis. We also investigated whether shell shape variation is best explained by environmental gradients or by genetic structuring, based on our prior molecular phylogeographic study. Two common morphological forms were observed among Chinese populations and in the adjacent Asian areas. Both the analyses revealed separation patterns in morphological variations of shell shape among the clades and populations. Environmental modelling analysis showed a significant correlation between shape variations and local maximum temperatures of the warmest month, indicating the role of natural selection in the evolution of this species. Data obtained in this study, combined with the cytochrome oxidase subunit I (COI) molecular phylogenetic data from the prior study, showed that morphological variations in M. labio were constrained by both local adaptation and phenotypic plasticity. We hypothesized that geographic separation by the Dongshan Landbridge was the first step towards its diversification, and that the temperature gradient between the East China Sea and South China Sea probably was the selective force driving the divergence of its morphological variations.

“…Additionally, both temperature and wave action are increasing with anthropogenic climate change (Pecl et al , 2017; Semedo et al , 2011). Lift and drag forces imparted by waves can dislodge rocky shore inhabitants (Denny and Blanchette, 2000; Forrester et al , 2016), so that muscle performance may have a direct influence on the survival of individuals within the wave-swept intertidal region. Temperature has profound effects on physiology in general and muscle performance specifically (Drake et al , 2017; James, 2013).…”

“…Gastropod snails are a conspicuous group of intertidal organisms, inhabiting virtually every microhabitat of wave-swept intertidal gradients around the world. Many gastropod species are distributed across high- and low-energy shores, which can influence intraspecific morphology (Forrester et al , 2016; Solas et al , 2015). For example, shells of exposed-shore populations are typically smaller and thinner, with larger foot surface areas when compared to protected-shore conspecifics (Trussell, 1997).…”

“…For example, anthropogenic climate change has already led to increased temperatures, increased wind speed and increased wave heights in oceans (Aarnes et al , 2017; Hemer et al, 2013; Young et al , 2011), as well as to ocean acidification (Doney et al , 2009). Increased wind speed and wave height may lead to increased physiological demand on birds (Nourani et al , 2017) and marine organisms (Bejarano et al , 2017; Forrester et al , 2016), respectively. At the same time, temperature changes alter physiological performance (James, 2013; Olberding and Deban, 2017), thereby modifying the impact of other drivers.…”

“…Adhesion strength, or tenacity (whole-animal dislodgement force per unit foot surface area, in N·cm −2 ), is influenced by foot surface area, and it depends on pedal mucus characteristics (Branch and Marsh, 1978; Iwamoto et al , 2014). The foot muscle has to produce greater force for the snail to stay in situ as wave action increases (Forrester et al , 2016), and the effect of wave impact is modulated by the size and shape of the organism (Trussell et al , 1993). Force needs to be produced over longer time periods if the increase in wave action is chronic.…”

Concurrent increases in wave action and sea surface temperatures increase the physical impact on intertidal organisms and affect their physiological capacity to respond to that impact. Our aim was to determine whether wave exposure altered muscle function in intertidal snails (Nerita atramentosa) and whether responses to wave action and temperature are plastic, leading to compensation for altered environmental conditions. We show that field snails from exposed shores had greater endurance and vertical tenacity than snails from matched protected shores (n = 5 pairs of shores). There were no differences in muscle metabolic capacities (strombine/lactate dehydrogenase, citrate synthase and cytochrome c oxidase activities) between shore types. Maximum stress (force/foot area) produced by isolated foot muscle did not differ between shore types, but foot muscle from snails on exposed shores had greater endurance. A laboratory experiment showed that vertical tenacity was greater in animals acclimated for 3 weeks to cool winter temperatures (15 C) compared to summer temperatures (25 C), but endurance was greater in snails acclimated to 25°C. Acclimation to water flow that mimicked wave action in the field increased vertical tenacity but decreased endurance. Our data show that increased wave action elicits a training effect on muscle, but that increasing sea surface temperature can cause a trade-off between tenacity and endurance. Ocean warming would negate the beneficial increase in tenacity that could render snails more resistant to acute impacts of wave action, while promoting longer term resistance to dislodgment by waves.

The ecology of Lepas-based biofouling communities on moored and drifting objects, with applications for marine forensic science

Pelagic biofoulers such as barnacles or bryozoans settle and raft on natural debris like pumice or seeds. Recent influxes of marine debris into the world's oceans, especially plastic, have increased habitat availability for these biofoulers. Goose barnacles in the genus Lepas are some of the most common biofouling taxa globally, and play an important role in biofouling communities as foundation species. We examined community succession, growth rates and isotopic composition in Lepas and their associated biofouling communities in coastal waters of eastern Australia. Community succession on a fixed surface mooring showed an increase in species diversity over 25 weeks. Using the abundances of L. anserifera, L. anatifera, and the amphipods Caprella danilevskii and Jassa slatteryi, we created an equation to estimate minimum duration at sea. Predators such as the polychaete Amphinome rostrata may influence the biofouling community, as can beach scavengers once floating debris is cast ashore. We report a new maximum growth rate for L. anserifera of 1.45 mm −1 , and our study is the first to report growth rates for any species of Lepas faster than 1 mm day −1 . Lepas were larger on moored floats than on smaller, free-floating drifters. δ 18 O content of Lepas shells was a robust predictor of sea surface temperatures during formation for L. anatifera and L. anserifera. Our findings have important applications for estimating drift duration and trajectories of marine debris.
