Marine heatwaves are global phenomena that can have major impacts on the structure and function of coastal ecosystems. By mid-2014, Pacific Heatwave (PMH) was evident in intertidal waters northern Gulf Alaska persisted for multiple years. While offshore marine ecosystems known to respond these warmer waters, response rocky this warming is unclear. Intertidal communities link terrestrial their resources important predators human food recreation, while simultaneously supporting a growing tourism industry. Given current climate change projections suggest increased frequency duration heatwaves, monitoring understanding habitats important. As part Watch Long-Term Monitoring program, we examined community at 21 sites across four regions spanning 1,200 km coastline: Western Prince William Sound, Kenai Fjords National Park, Kachemak Bay, Katmai Park Preserve. Sites were monitored annually from 2012 2019 mid low tidal strata. Before-PMH (2012–2014), differed among regions. We found macroalgal foundation species declined during period mirroring patterns observed elsewhere subtidal habitat formers heatwave events. The region-wide shift an autotroph-macroalgal dominated heterotroph-filter-feeder state concurrent with changing environmental conditions associated event suggests PMH had Gulf-wide communities.

Assessing the vulnerability of marine invertebrates to ocean acidification (OA) requires an understanding critical thresholds at which developmental, physiological, and behavioral traits are affected. To identify relevant for echinoderms, we undertook a three-step data synthesis, focused on California Current Ecosystem (CCE) species. First, literature characterizing echinoderm responses OA was compiled, creating dataset comprised >12,000 datapoints from 41 studies. Analysis this set demonstrated related physiology, behavior, growth development, increased mortality in larval adult stages low pH exposure. Second, statistical analyses were conducted selected pathways specific duration, taxa, depth-related life stage. Exposure reduced led impaired across range endpoints both stages. Third, through discussions expert panel identified eight duration-dependent, stage, habitat-dependent assigned each confidence score based quantity agreement evidence. The these effects ranged within 7.20 7.74 duration 7 30 days, all characterized with either medium or confidence. These yielded risk early warning lethal impacts, providing foundation consistent interpretation monitoring numerical model simulations support climate change assessments evaluation management strategies. As demonstration, two applied CCE visualize current state conditions potential habitat.

Chemical communication via infochemicals plays a pivotal role in ecological interactions, allowing organisms to sense their environment, locate predators, food, habitats, or mates. A growing number of studies suggest that climate change-associated stressors can modify these chemically mediated causing info-disruption scales up the ecosystem level. However, our understanding underlying mechanisms is scarce. Evidenced by range examples, we illustrate this opinion piece change affects different realms similar patterns, from molecular ecosystem-wide levels. We assess importance for terrestrial, freshwater, and marine ecosystems propose systematic approach address highlighted knowledge gaps cross-disciplinary research avenues.

For marine ectotherms, larval success, planktonic duration and dispersal trajectories are strongly influenced by temperature, therefore, ocean warming heatwaves have profound impacts on these sensitive stages. Warming, through increased poleward flow in regions with western boundary currents, such as the East Australia Current (EAC), provides opportunities for range extension propagules track preferred conditions. Two sea urchin species, Centrostephanus rodgersii Heliocidaris tuberculata, sympatric EAC hotspot, exhibit contrasting responses to warming. Over half a century, C. has undergone marked extension, but of H. tuberculata not changed. We constructed thermal performance curves (TPC) determine if developmental tolerance can explain this difference. The temperatures tested encompassed present-day distribution forecast warming/heatwave broad narrow optimum (Topt) ranges larvae (7.2 4.7°C range, respectively) matched their realized (adult distribution) niches. cool warm 50% development feeding larva approximated at adult limits.

Abstract Limpets ( Patella spp.) are marine gastropods that inhabit rocky shores along the coasts of Europe, Mediterranean, Macaronesia and north-west coast Africa. Being considered key species, limpets have an important role regulating algal assemblages in coastal communities. The goal this work was to evaluate influence sea temperature on respiration rate four limpet species occurring mainland Portugal, line with predictions from metabolic theory ecology. individuals were collected Portugal exposed temperatures ranging 6–28°C for assessments. Following estimation relationship between oxygen consumption activation energy calculated. In parallel, low high thermal thresholds determined three species. results indicated P. ulyssiponensis increased linearly remaining presented same tendency. values ranged 0.33–0.76 eV. For , highest is more sensitive variations while tested it a higher tolerance limit than other Such findings indicate most susceptible these climate change, tolerance–plasticity trade-off hypothesis. This provides good starting point understanding effect spp. comprehending sensitivity increases under future change scenarios.

Foundation species, which help maintain habitat and ecosystem functioning, are declining due to anthropogenic impacts. Within the rocky intertidal ecosystem, studies have investigated effects of foundation species on community structure some resource fluxes; however, how loss will affect multiple facets functioning in concert remains unknown. We studied direct indirect mussels Mytilus californianus surfgrass Phyllospadix spp. structure, fluxes (light, temperature, dissolved oxygen [DO], inorganic nutrients, pH T ), metabolism (net calcification [NEC] net production [NEP]) central Oregon using situ tide pool manipulations. Surfgrass increased microalgae cover, average maximum light by 142% temperature 3.8°C, DO values, indirectly NEP NEC via respectively. Mussel 5.8% 1.3°C, producer cover. Shifts baseline nutrient concentrations values from coastal upwelling influenced pools with intact species. Our results indicate that as communities respond loss, depends dominant present biologically or physically driven shifts biogeochemistry. This study highlights importance connection between ecology understanding magnitude changes occurring anthropogenically-driven loss.
