RNA‐seq reveals regional differences in transcriptome response to heat stress in the marine snail Chlorostoma funebralis

To investigate the role of gene expression in adaptation of marine ectotherms to different temperatures, we examined the transcriptome-wide thermal stress response in geographically separated populations of the intertidal snail Chlorostoma funebralis. Snails from two southern (heat tolerant) and two northern (heat sensitive) populations were acclimated to a common thermal environment, exposed to an environmentally relevant thermal stress and analysed using RNA-seq. Pooling across all populations revealed 306 genes with differential expression between control and heat-stressed samples, including 163 significantly upregulated and 143 significantly downregulated genes. When considered separately, regional differences in response were widely apparent. Heat shock proteins (Hsps) were upregulated in both regions, but the magnitude of response was significantly greater in northern populations for most Hsp70s, while the southern populations showed greater upregulation for approximately half of the Hsp40s. Of 177 stress-responsive genes in northern populations, 55 responded to heat stress only in northern populations. Several molecular chaperones and antioxidant genes that were not differentially expressed in southern populations showed higher expression under control conditions compared with northern populations. This suggests that evolution of elevated expression of these genes under benign conditions preadapts the southern populations to frequent heat stress and contributes to their higher thermal tolerance. These results indicate that evolution has resulted in different transcriptome responses across populations, including upregulation of genes in response to stress and preadaptation of genes in anticipation of stress (based on evolutionary history of frequent heat exposure). The relative importance of the two mechanisms differs among gene families and among populations.

“…There is growing evidence that both interannual and decadal shifts, either poleward or to deeper water, have caused a redistribution of marine organisms which partly associated with thermal habitat preference and changing temperature [72][73][74][75][76]. When testing the thermal tolerance of B. undatum to examine the possible impact of climate warming on range shift, Smith et al [19] found that during the early ontogeny, whelk possess thermal resilience to ocean warming; however, it comes at the cost of a reduced number of offspring. Successful development was greatest within their natural developmental temperature range (6-10 °C) but was observed up 18 °C, rates of development increased with temperatures yet the proportion of each egg mass developing successfully decreased [19].…”

“…Females aggregate during spawning and lay small spherical egg capsules that are deposited on hard surfaces such as rock or shell [15]. Larval development occurs inside the egg capsules and depending on location and temperature, egg masses take between 10 weeks to 9 months to develop into crawl-away juveniles [15,17,19].…”

“…Across the distribution of B. undatum, a broad thermal range is experienced by different populations with annual temperatures ranging from below 0 °C to above 22 °C [19]. Egg-laying and development do not occur over this entire temperature range and have been observed to be limited to temperatures between 2 and 10 °C [20] with thermal reproductive tolerance varying between populations.…”

“…Egg-laying and development do not occur over this entire temperature range and have been observed to be limited to temperatures between 2 and 10 °C [20] with thermal reproductive tolerance varying between populations. This variation in development timing has been linked to differences in temperature during development, where small increases in temperature, specifically at the lower end of the thermal range, result in shorter periods of development timing [19]. Juvenile whelk in the UK emerge from their egg capsules 3 to 5 months after egg-laying, while in Canada this takes place after 5 to 8 months [15,17].…”

Development of the unmanaged waved whelk (Buccinum undatum) fishery on the Mid-Atlantic continental shelf of the United States has initiated investigation into fisheries-related biological and population attributes of the species in this region. Maturation and reproduction timing vary by location for this species and are likely linked to bottom water temperature. This study examined the seasonal fluctuations in relevant body metrics and gonadosomatic index in relation to bottom temperature to assess the timing of the reproductive cycle of the B. undatum population in the southern-most extent of this species' range in the Atlantic. To characterize variation over the maturation schedule, nine locations in the Mid-Atlantic Bight (MAB) were sampled five times between January 2017 and September 2017.Maturity was assessed macroscopically, with morphological methods, and via gonadosomatic indices. Male behavioral maturity estimates, based on a penis length to shell length index (PL 50 ), were compared to estimates made using other methods for assessing maturity to test the efficacy of this commonly used ratio. Mature whelk were found in all months and peak reproductive activity was observed in spring and early summer. This timing suggests that ideal sampling to visually identify maturity to estimate size of maturity would be late winter or early spring. Unique oceanographic dynamics in the MAB, such as strong seasonal stratification results in large changes in annual bottom temperature which appears to be closely linked to the reproductive cycle in this region. Our data suggest that B. undatum in the MAB experience spawning and development at ~ 7-8 °C; temperatures warmer than Canadian populations and cooler than some UK conspecifics. To our knowledge, this is the first study to document the annual reproductive cycle of waved whelk in the United States.

Intraspecific polymorphism during development, such as poecilogony or dispersal polymorphism, has rarely been observed in the marine environment. The ecological advantages of this bet-hedging strategy, whereby the offspring from one species exhibit multiple developmental modes, include the potential for rapid colonization of new habitats while simultaneously achieving a degree of gene flow between populations. The muricid gastropod, Ocenebra erinaceus, is a common, shallow-water marine predator found across England and France. Historically, O. erinaceus caused significant damage to shellfisheries, but more recently it has been impacted by TBT-induced imposex. Despite the previous attention given to this species, little is known about its encapsulated development. Studying O. erinaceus egg capsules from the Solent, UK, we describe intracapsular development at 15°C, the in situ temperature at time of oviposition. Within each capsule, all embryos developed; no nurse eggs were present. Development was categorized into eight ontogenetic stages, although not all individuals displayed every stage; embryos hatched as either swimming late-pediveliger larvae or crawling juveniles after 59-69 days, indicating dispersal polymorphism to occur in this species. Swimming late-pediveliger larvae completed metamorphosis within 72 h of hatching. As O. erinaceus continues to recover from TBT pollution, dispersal polymorphism may facilitate a rapid expansion in both population size and range. If this occurs, O. erinaceus has the potential to, once again, become a serious problem for shellfisheries around Europe.
