• Macroalgal responses to ocean acidification depend on nutrient and light levels (2015, background): “…is likely to increase macroalgal productivity due to beneficial effects of increased dissolved inorganic carbon (DIC) levels which can stimulate the growth of algae and allows them to divert more resources into anti-herbivore and photo-protective compounds (Harley et al., 2012; Brodie et al., 2014).”
• The rise of Laminaria ochroleuca in the Western English Channel (UK) and comparisons with its competitor and assemblage dominant Laminaria hyperborea (2015, background): “Kelps are cool-water species that are stressed by high temperatures (Steneck et al. 2002; Wernberg et al. 2013); thus, seawater warming will affect the distribution, structure, productivity and resilience of kelp forests (Dayton et al. 1992; Wernberg et al. 2010; Harley et al. 2012).”
• Tropical rabbitfish and the deforestation of a warming temperate sea (2014, background): “physiology and recruitment (Harley et al., 2012), and may therefore also be contributing to the observed deforestation in the eastern Mediterranean.”
• Climate Change Impacts on Seagrass Meadows and Macroalgal Forests: An Integrative Perspective on Acclimation and Adaptation Potential (2018, background): “Marine macrophytes further provide ecosystem services, such as food for invertebrates and fish, a blue carbon sink, nutrient fixation, and protection of the coastline from erosion (Procaccini et al., 2007; Harley et al., 2012).”
• The ‘golden kelp’ Laminaria ochroleuca under global change: Integrating multiple eco‐physiological responses with species distribution models (2018, background): “While increasing attention has been recently devoted to the effects of environmental or/and anthropogenic factors on aquatic ecosystems (Crain, Kroeker, & Halpern, 2008; Halpern et al., 2008; Harley et al., 2012), these are often examined separately and considerable knowledge gaps remain concerning ”
• Seaweed production: overview of the global state of exploitation, farming and emerging research activity (2017, background): “3, large scientific investments are needed to determine the ecological effects of climaterelated chemical, ecological and biological (e.g. invasive algae) processes that may impact the seaweed industry (Harley et al., 2012; Ji et al., 2016; KruegerHadfield et al., 2017).”
• Sea urchin barrens as alternative stable states of collapsed kelp ecosystems (2014, neutral): “Second, it is not possible to manage phase shifts re sulting from environmental changes, such as warming oceans, increased storm severity, and altered currents (Ebeling et al. 1985, Ling 2008, Harley et al. 2012, Scheibling et al. in press).”
• Can ecosystem functioning be maintained despite climate‐driven shifts in species composition? Insights from novel marine forests (2018, positive): “Although climate-driven reconfigurations of seaweed communities are well-documented (Harley et al. 2012), empirical evidence for their wider ecological consequences remains limited, and understanding how altered species composition affects ecosystem processes and functioning remains a persistent…”
• European seaweeds under pressure: Consequences for communities and ecosystem functioning (2015, background): “Temperature will affect physiological processes altering phenology, growth rate and ultimately the fitness of the different species in differentwayswith population and community level implications that may include catastrophic shifts (Harley et al., 2012).”
• Field scale evaluation of seaweed aquaculture as a nutrient bioextraction strategy in Long Island Sound and the Bronx River Estuary (2014, background): “With global climatic change, the Gracilaria growing season will be extended, resulting in even greater bioextraction by Gracilaria (Harley et al., 2012; Ugarte et al., 2010).”
• The role of kelp species as biogenic habitat formers in coastal marine ecosystems (2017, background): “As such, seawater 783 warming (in association with global climate change) will impact the distribution, productivity, 784 resilience and structure of kelp forests (Harley et al., 2012; Merzouk and Johnson, 2011; Wernberg 785 et al., 2010).”
• The future of seaweed aquaculture in a rapidly changing world (2017, background): “In the case of tropical seaweeds, the final impact of warming and OA would depend on the extent of fisheries exploitation and thus top-down pressure on the algae (Harley et al., 2012).”
• Factors affecting yield and gelling properties of agar (2016, background): “The amount of dissolved oxygen (DO) and carbon dioxide (DC) in the seawater may change drastically due to global climate change (Harley et al. 2012), causing ocean acidification, which may affect seaweed populations and their agar production.”
