Here we report genome Zostera marina (L.), first, our knowledge, marine angiosperm be fully sequenced. This reveals unique insights into genomic losses gains involved in achieving structural physiological adaptations required for its lifestyle, arguably severe habitat shift ever accomplished by flowering plants. Key innovations that were lost...
Abstract The North‐Atlantic has warmed faster than all other ocean basins and climate change scenarios predict sea surface temperature isotherms to shift up 600 km northwards by the end of 21st century. pole‐ward already begun for many temperate seaweed species that are important intertidal foundation species. We asked question: Where will have greatest impact on three foundational, macroalgal occur along shores: Fucus serratus , vesiculosus, Ascophyllum nodosum ? To distributional changes...
Marine macrophytes are the foundation of algal forests and seagrass meadows¬–some most productive diverse coastal marine ecosystems on planet. These provide nursery grounds food for fish invertebrates, coastline protection from erosion, carbon sequestration, nutrient fixation. For macrophytes, temperature is generally important range limiting factor, ocean warming considered severe threat among global climate change factors. induced losses dominant along their equatorial edges, as well...
Abstract Rising temperatures are predicted to melt all perennial ice cover in the Arctic by end of this century, thus opening up suitable habitat for temperate and subarctic species. Canopy‐forming seaweeds provide an ideal system predict potential impact climate‐change on rocky‐shore ecosystems, given their direct dependence temperature key role ecological system. Our primary objective was induced range‐shift Fucus distichus , dominant canopy‐forming macroalga rocky intertidal. More...
The utility of species distribution models for applications in invasion and global change biology is critically dependent on their transferability between regions or points time, respectively. We introduce two methods that aim to improve the presence-only models: density-based occurrence thinning performance-based predictor selection. evaluate effect these along with impact choice model complexity geographic background a regions. Our multifactorial experiment focuses notorious invasive...
Brown seaweeds are keystone species of coastal ecosystems, often forming extensive underwater forests, and under considerable threat from climate change. In this study, analysis multiple genomes has provided insights across the entire evolutionary history lineage, initial emergence, through later diversification brown algal orders, down to microevolutionary events at genus level. Emergence lineage was associated with a marked gain new orthologous gene families, enhanced protein domain...
Marine spatial planning that addresses ocean climate-driven change ('climate-smart MSP') is a global aspiration to support economic growth, food security and ecosystem sustainability. Ocean climate ('CC') modelling may become key decision-support tool for MSP, but traditional analysis communication challenges prevent their broad uptake. We employed MSP-specific analyses inform real-life MSP process; addressing how nature conservation fisheries could be adapted CC. found the currently planned...
Seagrasses play a vital role in structuring coastal marine ecosystems, but their distributional range and genetic diversity have declined rapidly recent decades. To improve conservation of seagrass species, it is important to predict how climate change may impact ranges. Such predictions are typically made with correlative species distribution models (SDMs), which can estimate species' potential under present future climatic scenarios given presence data predictor variables. However, these...
SUMMARY Brown seaweeds are keystone species of coastal ecosystems, often forming extensive underwater forests, that under considerable threat from climate change. Despite their ecological and evolutionary importance, this phylogenetic group, which is very distantly related to animals land plants, still poorly characterised at the genome level. Here we analyse 60 new genomes include all major brown algal orders. Comparative analysis these indicated occurrence several events coinciding...

Abstract Populations distributed across a broad thermal cline are instrumental in addressing adaptation to increasing temperatures under global warming. Using space‐for‐time substitution design, we tested for parallel warm along two independent clines Zostera marina , the most widely seagrass temperate Northern Hemisphere. A North–South pair of populations was sampled European and North American coasts exposed simulated heatwave common‐garden mesocosm. Transcriptomic responses control, heat...
Marine macrophytes, including seagrasses and macroalgae, form the basis of diverse productive coastal ecosystems that deliver important ecosystem services. Moreover, western countries increasingly recognize traditionally cultivated in Asia, as targets for a new bio-economy can be both economically profitable environmentally sustainable. However, seagrass meadows macroalgal forests are threatened by variety anthropogenic stressors. Most notably, rising temperatures marine heatwaves already...
Sex-biased gene expression is considered to be an underlying cause of sexually dimorphic traits. Although the nature and degree sex-biased have been well documented in several animal plant systems, far less known about evolution genes more distant eukaryotic groups. Here, we investigate two brown algal dioecious species, Fucus serratus vesiculosus, where male heterogamety (XX/XY) has recently emerged. We find that contrast evolutionary lineages, male-biased do not experience high turnover...

This review summarizes main challenges, such as top‐down fragmented management libraries, well private industry without government regulations, inter‐cultivar accidental admixing genetic erosion, loss heterozygosity due...
Advances in next-generation sequencing technologies and the development of genome-reduced representation protocols have opened way to genome-wide population studies non-model species. However, species with large genomes remain challenging, hampering genomic resources for a number taxa including marine arthropods. Here, we developed method ecologically important copepod Calanus finmarchicus (haploid genome size 6.34 Gbp). We optimized capture enrichment-based protocol based on 2656...
Evolutionary theory predicts that clonal organisms are more susceptible to extinction than sexually reproducing organisms, due low genetic variation and slow rates of evolution. In agreement, conservation management considers as the ultimate measure a population's ability survive over time. However, plants among oldest living on our planet. Here, we test hypothesis seagrass meadows display epigenetic complements source phenotypic variation. meadow Zostera marina, characterized DNA...
It is unclear whether intertidal organisms are ‘preadapted’ to cope with the increase of temperature and variability or if they currently at their thermal tolerance limits. To address dichotomy, we focused on an important ecosystem engineer Arctic rocky shores, seaweed Fucus distichus investigated stress responses two populations from different regimes (Svalbard Kirkenes, Norway). Thermal 20°C, 24°C 28°C were assessed by measuring photosynthetic performance expression heat shock protein...
Abstract Most kelp species are of high ecological and economic importance worldwide, but highly susceptible to rising ocean temperatures due their sessile lifestyle. Due interference with reproduction, development growth, natural forests have vanished in multiple regions after extreme summer heat waves. Furthermore, increasing likely decrease biomass production and, thus, reduce security farmed kelp. Epigenetic variation, cytosine methylation as a heritable epigenetic trait, is rapid means...
