Rising atmospheric carbon dioxide (CO 2 ) conditions are driving unprecedented changes in seawater chemistry, resulting reduced pH and carbonate ion concentrations the Earth’s oceans. This ocean acidification has negative but variable impacts on individual performance many marine species. However, little is known about adaptive capacity of species to respond an acidified ocean, and, as a result, predictions regarding future ecosystem responses remain incomplete. Here we demonstrate that...
SUMMARY Anthropogenic CO2 is reducing the pH and altering carbonate chemistry of seawater, with repercussions for marine organisms ecosystems. Current research suggests that calcification will decrease in many species, but compelling evidence impaired functional performance calcium structures sparse, particularly key species. Here we demonstrate ocean acidification markedly degrades mechanical integrity larval shells mussel Mytilus californianus, a critical community member on rocky shores...
Predicting impacts of global environmental change is challenging due to the complex life cycles that characterize many terrestrial and aquatic taxa. Different stages often interact with physical environment in distinct ways, a growing body work suggests stresses experienced during one stage can "carry over" influence subsequent stages. Assessments population responses perturbation must therefore consider how effects might propagate across life-history transitions. We investigated...
The near-term progression of ocean acidification (OA) is projected to bring about sharp changes in the chemistry coastal upwelling ecosystems. distribution OA exposure across these early-impact systems, however, highly uncertain and limits our understanding whether how spatial management actions can be deployed ameliorate future impacts. Through a novel observing network, we have uncovered remarkably persistent mosaic penetration acidified waters into ecologically-important nearshore...
Success and impact metrics in science are based on a system that perpetuates sexist racist “rewards” by prioritizing citations factors. These flawed biased against already marginalized groups fail to accurately capture the breadth of individuals’ meaningful scientific impacts. We advocate shifting this outdated value advance through principles justice, equity, diversity, inclusion. outline pathways for paradigm shift values multidimensional mentorship promoting mentee well-being. actions...
Abstract Although theory suggests geographic variation in species' performance is determined by multiple niche parameters, little consideration has been given to the spatial structure of interacting stressors that may shape local and regional vulnerability global change. Here, we use spatially explicit mosaics carbonate chemistry, food availability temperature spanning 1280 km coastline test whether persistent, overlapping environmental mediate growth predation a critical foundation species,...
There is growing concern that global environmental change might exacerbate the ecological impacts of invasive species by increasing their per capita effects on native species. However, mechanisms underlying such shifts in interaction strength are poorly understood. Here, we test whether ocean acidification, driven elevated seawater p CO 2 , increases susceptibility Olympia oysters to predation snails. Oysters raised under experienced a 20% increase drilling predation. When presented...
An extensive body of work suggests that altered marine carbonate chemistry can negatively influence invertebrates, but few studies have examined how effects are moderated and persist in the natural environment. A particularly important question is whether impacts initiated early life might be exacerbated or attenuated over time presence absence other stressors field. We reared Olympia oyster (Ostrea lurida) larvae laboratory cultures under control elevated seawater pCO2 concentrations,...
Climate-driven Oxygen Minimum Zone (OMZ) expansions in the geologic record provide an opportunity to characterize spatial and temporal scales of OMZ change. Here we investigate expansion through global-scale warming event most recent deglaciation (18-11 ka), with clear relevance understanding modern anthropogenic climate Deglacial marine sediment records were compiled quantify vertical extent, intensity, surface area volume impingements hypoxic waters upon continental margins. By integrating...

Thus, CCLME critical study rate of that resident organisms will and because economic societal value this coastal region. Recent efforts research consortium –...
Abstract Global‐scale ocean acidification has spurred interest in the capacity of seagrass ecosystems to increase seawater pH within crucial shoreline habitats through photosynthetic activity. However, dynamic variability coastal carbonate system impeded generalization into whether aerobic metabolism ameliorates low on physiologically and ecologically relevant timescales. Here we present results most extensive study date modulation by seagrasses, spanning seven meadows ( Zostera marina )...
Abstract. Increases in atmospheric carbon dioxide drive accompanying changes the marine carbonate system as (CO2) enters seawater and alters ocean pH (termed "ocean acidification"). However, such do not occur isolation, other environmental factors have potential to modulate consequences of altered chemistry. Given that physiological mechanisms used by organisms confront acidification can be energetically costly, we explored for food supply influence response Olympia oyster (Ostrea lurida)...
Ocean acidification (OA) is occurring across a backdrop of concurrent environmental changes that may in turn influence species' responses to OA. Temperature affects many fundamental biological processes and governs key reactions the seawater carbonate system. It therefore has potential offset or exacerbate effects While initial studies have examined combined impacts warming OA for narrow range climate change scenarios, our mechanistic understanding interactive temperature remains limited....
Organism-level effects of ocean acidification (OA) are well recognized. Less understood OA's consequences for ecological species interactions. Here, we examine a behaviourally mediated predator-prey interaction within the rocky intertidal zone temperate eastern Pacific Ocean, using it as model system to explore capacity impair invertebrate anti-predator behaviours more broadly. Our involves iconic sea star predator, Pisaster ochraceus, that elicits flee responses in numerous gastropod prey....
Significance This investigation presents the first record to our knowledge of disturbance and recovery seafloor ecosystem biodiversity in response abrupt climate change. Ocean sediments have been extensively studied using geochemical microfaunal (e.g., Foraminifera) analyses; however, these traditional approaches produce limited interpretations ecological community-scale responses. We demonstrate here that ocean harbor metazoan fossil material can be used reconstruct global-scale events....
The northeastern Pacific Ocean is undergoing changes in temperature, carbonate chemistry, and dissolved oxygen concentration concert with global change. Each of these stressors has wide-ranging effects on physiological systems, which may differ among species life-history stages. Simultaneous exposure to multiple lead even stronger impacts organisms, but interacting remain poorly understood. Here, we examine how single- multiple-stressor physiology drive the behavior, biogeography, ecosystem...
The oxygen minimum zone (OMZ) of the late Quaternary California margin experienced abrupt and dramatic changes in strength depth response to intermediate water ventilation, ocean productivity, climate at orbital through millennial time scales.

[1] Here we present a history of deoxygenation upper intermediate waters during the last deglaciation from Santa Barbara Basin (SBB), based on quantitative analyses benthic foraminiferal assemblages, new shallow piston core above basin sill depth (MV0811-15JC, 418 m), and previously described sequences in deeper (MD02-2504, 481 m MD02-2503, 570 m). We document 152 transect assemblages to extract changing community structure (density, diversity, evenness) improve paleoenvironmental...
Anthropogenic emissions of carbon dioxide (CO2) are causing ocean acidification, lowering seawater aragonite (CaCO3) saturation state (Ω arag), with potentially substantial impacts on marine ecosystems over the 21(st) Century. Calcifying organisms have exhibited reduced calcification under lower conditions in aquaria. However, situ sensitivity calcifying to future acidification remains unknown. Here we assess community level local CO2-induced caused by natural respiration an unperturbed,...
Ocean acidification (OA) poses a major threat to marine ecosystems and shellfish aquaculture. A promising mitigation strategy is the identification breeding of varieties exhibiting resilience stress. We experimentally compared effects OA on two populations red abalone (Haliotis rufescens), mollusc important fisheries global Results from our experiments simulating captive aquaculture conditions demonstrated that sourced strong upwelling region were tolerant ongoing OA, whereas captive-raised...
