“…S3 in Supplementary Information 2) caused changes in the abundance rate of M. japonicus / M. banzai ; however, the temperature tolerance of each species was not evaluated in the present study. The temperature tolerance of the target species must be evaluated to understand the expansion and/or contraction of its distribution range 27 , 41 . Further research is required to address these gaps regarding the ecological traits of the two species.…”

“…To address this gap, the objective of the present study was to monitor intertidal sediment temperatures and investigate the distribution of these two species in western Japan and their relationships with intertidal sediment temperature. Winter temperatures have been shown to affect the survival and distribution expansion of brachyuran crab larvae and juveniles 25 – 27 . Based on the information that M. japonicus and M. banzai are dormant in the intertidal sediment during winter 16 , we hypothesized that the spatial distribution patterns of these two species are closely related to the intertidal sediment temperature during that season.…”

In the context of global climate change, monitoring focused on temperature and benthic animals in intertidal flats and the development of metrics to assess climate change and ecosystem responses are essential for a sustainable society. However, few studies have assessed the relationship between intertidal sediment temperature and the distribution of benthic animals. To address this gap, in the present study, intertidal sediment temperatures were observed in 12 intertidal flats in 11 survey areas over 335 days, from October 2, 2019, to August 31, 2020, using water temperature data loggers. The characteristics of intertidal sediment temperatures were variable among the survey areas, and a correlation analysis suggested that such characteristics are possibly influenced by various spatial-scale factors, such as geographical, basin, and habitat scales. Furthermore, two sentinel crab species, Macrophthalmus japonicus and Macrophthalmus banzai were collected, and the number of wintering individuals of each species was estimated based on their carapace width to analyze the changes in abundances of the two species in each survey area. The results show that the number of days with daily minimum temperature ≥ 19 °C was the factor that influenced the abundance rate, suggesting that M. japonicus and M. banzai populations may decrease and increase, respectively, according to future climate change in Japan. Our findings emphasize the importance of long-term monitoring of sediment temperatures and benthic animals in intertidal flats to evaluate the influence of future climate change.

“…This coincides with other global research on marine organisms (Cheung et al, 2009; Poloczanska et al, 2016; Sunday et al, 2012), including Heterobranchia (Goddard et al, 2011, 2016; Nimbs & Smith, 2016). Specifically, in the West Atlantic Ocean, distributional poleward shifts have been documented for fiddler crabs (De Grande et al, 2021), common snook (Purtlebaugh et al, 2020), dinoflagellates (Kibler et al, 2015) and another species of sea slug, Bulla occidentalis (Saupe et al, 2014). In contrast, another climate change research forecasted that some gastropod in this region will not shift their distribution poleward as temperatures warm (Saupe et al, 2014), and that difference could be due to the complexity of each species’ niche.…”

Biodiversity and conservation of “solar‐powered” sea slugs from the Western Atlantic under climate change scenarios

Elysiais a genus of sea slugs in which some species can "steal" chloroplasts (kleptoplasty) from algae and keep them photosynthetically active inside their cells. Solarpowered animals are more susceptible to climate change as photosynthesis can increase the stress for these animals in extreme environmental conditions. Here, we used the Maxent algorithm and environmental envelopes (i.e. the multi-dimensional environmental space in which a species can occur) to model the ecological niche of 21 Elysia species in the Caribbean to estimate their current and future potential distribution. We then used predicted distributions to map potential taxonomical richness and to describe the representation of the genus inside the marine protected areas (MPAs). For most species, we show an expansion of the northern and southern range of distribution, but a reduction in the central part. Although changes in richness appeared in different areas, predictions emphasize four large extensions that have a potential current richness of 13 and will have no species in the future: Pamlico Sound, North Carolina; the southwest of the Gulf of Mexico; the Great Bahama Bank; and the southwest of Brazil. Out of the total area with environmental conditions adequate for at least one of the species in the genus, 24.7% is located within MPAs.
