“…This is consistent with Lusitanian toadfish males decreasing in size with the progression of the reproductive season suggesting that smaller males only get access to these nests when competition starts to decrease. In line with this suggestion, Bose et al (2019) recently found that the batrachoidid plainfin midshipman, Porichthys notatus, preferred to nest in the lower intertidal zone but still occupied nests in the higher levels of the intertidal gradient (especially smaller males) despite facing higher physiological stress (increased anaerobic metabolism) and greater offspring mortality. These authors also attributed this pattern of nest occupation to the high competition for nest sites in the breeding season.…”

“…High rates of nest turnover, as well as the robust correlation between male body size and nest size, indicate that the plainfin midshipman breeding season is rife with male–male competition to control limited high‐quality sites (Bose et al., 2014, 2018; DeMartini, 1988, 1991). As nest size was held constant in our study by the use of identical tiles, the presence of the largest males in low intertidal nests suggests competition was most intensive at this elevation (Bose, Borowiec, et al., 2019). It is conceivable that factors other than competition could explain the pattern of size‐assortative nesting we observed.…”

Parents providing care must sometimes choose between rearing locations that are most favourable for offspring versus those that are most favourable for themselves. Here, we measured how both parental and offspring performance varied in nest sites distributed along an environmental gradient. The plainfin midshipman fish Porichthys notatus nests along a tidal gradient. When ascending from the subtidal to the high intertidal at low tide, both nest temperature and frequency of air exposure increase. We used one lab and two field experiments to investigate how parental nest site choices across tidal elevations are linked to the physiological costs incurred by parents and the developmental benefits accrued by offspring. Under warmer incubation conditions, simulating high intertidal nests, offspring developed faster but had higher mortality rates compared to those incubated in cooler conditions that mimicked subtidal nests. In the field, males in higher intertidal nests were more active caregivers, but their young still died at the fastest rates. Larger males claimed and retained low intertidal nests, where offspring survival and development rates were also highest. Our results suggest that males compete more intensively for nest sites in the low intertidal, where they can raise their young quickly and with lower per‐offspring investments. Smaller, less‐competitive males forced into higher intertidal sites nest earlier in the season and provide more active parental care, possibly to bolster brood survival under harsh environmental conditions.

“…There are also several subtidal fishes (e.g., plainfin midshipman, Porichthys notatus; sharpnose sculpin, Clinocottus acuticeps; white stickleback, Gasterosteus sp.) that enter the high intertidal zone solely to construct nests, spawn, and in some cases provide parental care (e.g., guarder males), in order to take advantage of its several benefits (Martin et al 2004, Bose et al 2019.…”

The high intertidal zone is home to an incredible variety of marine animals, as it offers an escape from low intertidal/subtidal predation and competition, among other advantages. However, this area of the shore also comes with many tide-driven and emersion-associated environmental stressors, such as desiccation, high temperatures and freezing stress, hypoxia, salinity fluctuations, nitrogenous waste accumulation, ultraviolet (UV) radiation, wave and ice disturbance, and hydrogen sulphide (H2S) toxicity. This review explores the diversity of evolutionary adaptations and plastic phenotypic responses that high intertidal animals use to cope with these challenges. Examples are provided of behavioural, morphological, physiological and biochemical adaptations/responses, along with some of the underlying molecular mechanisms that have been elucidated to date. Adaptations of many different worms, anemones, molluscs, crustaceans and fishes are highlighted. Many adaptations and mechanisms of plasticity are universal among animal phyla, and some are multifunctional (serve more than one function) or provide tolerance to multiple stressors (i.e., ‘cross-tolerance’). High intertidal animals have received considerable attention by scientists, given their accessibility and that they can provide valuable insights in the transition from a marine to a terrestrial lifestyle. Nevertheless, further research is needed to understand the adaptations/responses of these animals more thoroughly, and the future holds great promise for accomplishing this with recent advances in epigenetics, transcriptomics, protein biochemistry and other molecular tools.
