It is also worth to mention that this study does not consider non-climate stressors that could be already affecting the sensitivity and adaptive capacity of marine organisms (e.g., pollution, relevant land use change, marine traffic and noise, appearance of invasive species, changing demand by consumers, etc.)…”

This is the first attempt to apply an expert-based ecological vulnerability assessment of the effects of climate change on the main marine resources of Portugal. The vulnerability, exposure, sensitivity, adaptive capacity, and expected directional effects of 74 species of fish and invertebrates of commercial interest is estimated based on criteria related to their life-history and level of conservation or exploitation. This analysis is performed separately for three regions of Portugal and two scenarios of climate change (RCP 4.5 and RCP 8.5). To do that, the fourth assessment report IPCC framework for vulnerability assessments was coupled to the outputs of a physical-biogeochemical model allowing to weight the exposure of the species by the expected variability of the environmental variables in the future. The highest vulnerabilities were found for some migratory and elasmobranch species, although overall vulnerability scores were low probably due to the high adaptive capacity of species from temperate ecosystems. Among regions, the highest average vulnerability was estimated for the species in the Central region while higher vulnerabilities were identified under climate change scenario RCP 8.5 in the three regions, due to higher expected climatic variability. This work establishes the basis for the assessment of the vulnerability of the human activities relying on marine resources in the context of climate change.

“…Accordingly, gentle slopes are associated with dissipative coastal stretches where wave entrainment is facilitated with respect to more stepper, reflective coasts where waves rebound seawards (Defeo and McLachlan 2011 ; Morgan et al 2017 ; Zhang et al 2021 ). In fact, the transport of sediment and planktonic larvae driven by orbital currents across the surf zone is known to be maximised at flat shores (Navarrete et al 2015 ; Shanks et al 2017 ; Weidberg et al 2018 ). On the other hand, the increases in wave period associated with the largest swells are known to increase wave reflection especially at steep shorelines (Muttray et al 2006 ; Mahmoudof et al 2021 ).…”

“…1 c). The diameter of the circle was chosen to capture the main interactive effects between nearshore topography and wave forcing (Weidberg et al 2018 ). Then, to get a proxy of the coastline orientation around the sites, a line was drawn between the 2 coastline-circle intersection points (Rivera et al 2016a , b ).…”

“…Furthermore, the topographic characteristics of each extraction site along the coast match remarkably well the quality of the resource, with higher frequencies of wider animals at more exposed and wavy locations (Rivera et al 2016a , b ). Accordingly, key nearshore landscape metrics like bottom slope, orientation and complexity are known to regulate many different coastal processes, including larval dispersal, settlement and sediment transport and retention (Kamphuis et al 1986 ; Wolanski and Spagnol 2000 ; Defeo and McLachlan 2011 ; Morgan et al 2017 ; Shanks et al 2017 ; Weidberg et al 2018 ). Therefore, one could argue that if spatial variability in wave forcing regulates barnacle morphology along the coast, temporal variability in wave climate may also impact barnacle populations.…”

Wave climate is shifting over the last decades along the Atlantic coasts of Europe ultimately driven by large-scale patterns of atmospheric variability forced by anthropogenic global warming. Changes in wave height and surf zone orbital currents are hypothesized to drive marked shifts in the shape of intertidal organisms such as the stalked barnacle Pollicipes pollicipes, whose quality and market price are known to decrease non linearly with the peduncle length: width ratio S. This study evaluates wave trends in NW Iberian Peninsula, using the Spanish Port System 2006–2020 SIMAR wave hindcast. On the other hand, trends in stalked barnacle morphology and quality are estimated from 26 sites at the management regions of Baiona and A Guarda between 2011 and 2020. Results show evidence of temporal changes in barnacle quality and, especially, morphometry caused by simultaneous shifts in winter wave induced orbital currents. Because of the non linear relationship between S and the high quality threshold, large increases in S are usually translated to small reductions in quality. However, we identified a tipping point around S = 2.4 that if surpassed can lead to great drops in barnacle quality. In addition, changes in wave forcing will have different effects at each extraction site, as trends in wave climate are decoupled from barnacle morphometry at steeper sites sheltered from the predominant wave direction. In conclusion, this knowledge could be applied to develop site specific barnacle harvesting strategies based on annual wave climate forecasts. Graphical abstract

“…Recruitment is a determinant factor influencing population increase or decrease and depends on a number of biotic and environmental factors (Roughgarden et al, 1988 ). Populations can be either closed or open in terms of recruitment, and for species with highly dispersive propagules (Cowen et al, 2000 ), this is strongly regulated by the physical parameters influencing dispersal (Haye et al, 2014 ; Weidberg et al, 2018 ). Furthermore, such factors can operate at a wide variety of spatial and temporal scales (Gaines & Roughgarden, 1985 ; Kinlan et al, 2005 ).…”

Effects of habitat quality on abundance, size and growth of mussel recruits

et al. 2022

Recruitment of mussels is a complex process with the successful arrival of individuals hinging on the availability of suitable habitats. We examined the effects of adult mussels as settlement habitat and the degree to which the suitability of habitat they offer is species-specific by comparing the recruitment success of intertidal mussels. We hypothesised that mussel recruitment and early growth are dictated by the quality of habitat offered by conspecifics adults. We used a unique experimental arena on the south coast of South Africa, where Mytilus galloprovincialis and two lineages of Perna perna co-exist. Treatments were based on the translocation of individuals of M. galloprovincialis , western- and eastern lineage of P . perna to a single site, where artificial beds were created and sampled monthly over one year. Recruit’s number, their sizes and growth were greater within beds of the western lineage of Perna than eastern lineage or Mytilus beds. The results clearly demonstrate that the quality of settlement habitat offered by adult beds differs among adult lineages/species and affects rates of settlement and the early growth of recruits. This effect extends to the intraspecific level; we found greater differences in density and growth of recruits between lineages of Perna than between either lineage and M. galloprovincialis .
