Increases in the frequency, severity and duration of temperature extremes are anticipated near future. Although recent work suggests that changes variation will have disproportionately greater effects on species than to mean, much climate change research ecology has focused impacts mean change. Here, we couple fine-grained projections (2050-2059) thermal performance data from 38 ectothermic invertebrate contrast with those a simple model. We show based alone differ substantially...
The interaction of climate and the timing low tides along West Coast United States creates a complex mosaic thermal environments, in which northern sites can be more thermally stressful than southern sites. Thus, change may not lead to poleward shift distribution intertidal organisms, as has been proposed, but instead will likely cause localized extinctions at series "hot spots." Patterns exposure extreme climatic conditions are temporally variable, tidal predictions suggest that next 3 5...
Climate change can affect organisms both directly via physiological stress and indirectly changing relationships among species. However, we do not fully understand how interspecific contribute to community- ecosystem-level responses environmental forcing. I used experiments spatial temporal comparisons demonstrate that warming substantially reduces predator-free space on rocky shores. The vertical extent of mussel beds decreased by 51% in 52 years, reproductive populations mussels...
We explicitly quantified spatial and temporal patterns in the body temperature of an ecologically important species intertidal invertebrate, mussel Mytilus californianus, along majority its latitudinal range from Washington to southern California, USA. Using long-term (five years), high-frequency records recorded at multiple sites, we tested hypothesis that local "modifying factors" such as timing low tide summer can lead large-scale geographic mosaics temperature. Our results show during...
Changing temperature can substantially shift ecological communities by altering the strength and stability of trophic interactions. Because many rates are constrained temperature, new approaches required to understand how simultaneous changes in multiple alter relative performance species their We develop an energetic approach identify relationship between biomass fluxes standing across levels. Our links dynamics measure temperature-dependent interactions determine these food web stability....
The global acidification of the earth's oceans is predicted to impact biodiversity via physiological effects impacting growth, survival, reproduction, and immunology, leading changes in species abundances distributions. However, degree which these will play out critically depends on evolutionary rate at populations respond natural selection imposed by ocean acidification, remains largely unquantified. Here we measure potential for an response larval development two coastal invertebrates...
Ocean acidification, chemical changes to the carbonate system of seawater, is emerging as a key environmental challenge accompanying global warming and other human-induced perturbations. Considerable research seeks define scope character potential outcomes from this phenomenon, but crucial impediment persists. Ecological theory, despite its power utility, has been only peripherally applied problem. Here we sketch in broad strokes several areas where fundamental principles ecology have...
In late June 2021 a heatwave of unprecedented magnitude impacted the Pacific Northwest region Canada and United States. Many locations broke all-time maximum temperature records by more than 5 °C, Canadian national record was broken 4.6 with new 49.6 °C. Here, we provide comprehensive summary this event its impacts. Upstream diabatic heating played key role in anomaly. Weather forecasts provided advanced notice event, while sub-seasonal showed an increased likelihood heat extreme lead times...

Rocky intertidal ecosystems are characterized by marked zonation patterns in which species replace one another along the vertical gradient of emersion time. Yet, we still do not fully understand reasons that variable space and Here, use effective shore level (ESL), a metric incorporates modifying influence wave splash, to describe relationship between uninterrupted time two ecologically important species: mussel Mytilus californianus barnacle Balanus glandula .

Anthropogenic climate change poses a serious threat to biodiversity. In marine environments, multiple variables, including temperature and CO(2) concentration ([CO(2)]), are changing simultaneously. Although has well-documented ecological effects, many heavily calcified organisms experience reduced growth with increased [CO(2)], little is known about the combined effects of particularly on species that less dependent shells or skeletons. We manipulated water [CO(2)] determine sea star...

▪ Abstract The Exxon Valdez oil spill was the largest in US maritime history. We review post-spill research and set it its legal context. Corporation, obviously responsible for spill, focused on restoration, whereas Trustees, a coalition of state federal entities, damage assessment. Despite billions dollars expended, little new understanding gained about recovery dynamics high latitude marine ecosystem subject to an anthropogenic pulse perturbation. discuss variety case studies that...
Ecological studies often focus on average effects of environmental factors, but ecological dynamics may depend as much upon extremes. Ecology would therefore benefit from the ability to predict frequency and severity extreme events. Some events (e.g., earthquakes) are simple events: either they happen or don't, generally difficult predict. In contrast, compound events, resulting chance coincidence run‐of‐the‐mill factors. Here we present an bootstrap method for resampling short‐term data...
Biological responses to climate change are typically communicated in generalized terms such as poleward and altitudinal range shifts, but adaptation efforts relevant management decisions often require forecasts that incorporate the interaction of multiple climatic nonclimatic stressors at far smaller spatiotemporal scales. We argue desire for generalizations has, ironically, contributed frequent conflation weather with climate, even within scientific community. As a result, current...
Trophic cascades are indirect positive effects of predators on resources via control intermediate consumers. Larger-bodied appear to induce stronger trophic (a greater rebound resource density toward carrying capacity), but how this happens is unknown because we lack a clear depiction the strength determined. Using consumer models, first show that cascade has an upper limit set by interaction between basal group and its approached as predator increases. We then express explicitly in terms...
Summary Small‐scale distributions of rocky intertidal organisms may be determined in part by temperature and desiccation stress during low tide the ability to resist such stresses. Biophysical modelling techniques, coupled with data on physiological tolerance can used predict frequency severity abiotic events. The limpet Lottia gigantea is a major competitor for primary space shores along west coast North America. goal this study was quantify thermal species stressful events at Hopkins...
Most studies that forecast the ecological consequences of climate change target a single species and life stage. Depending on climatic impacts other stages interacting species, however, results from simple experiments may not translate into accurate predictions future change. Research needs to move beyond experimental environmental envelope projections for towards identifying where ecosystem is likely occur drivers this For happen, we advocate research directions (i) identify critical within...
