Ocean acidification represents a threat to marine species worldwide, and forecasting the ecological impacts of is high priority for science, management, policy. As research on topic expands at an exponential rate, comprehensive understanding variability in organisms' responses corresponding levels certainty necessary forecast effects. Here, we perform most meta-analysis date by synthesizing results 228 studies examining biological ocean acidification. The reveal decreased survival,...
Anthropogenic environmental changes, or ‘stressors’, increasingly threaten biodiversity and ecosystem functioning worldwide. Multiple-stressor research is a rapidly expanding field of science that seeks to understand ultimately predict the interactions between stressors. Reviews meta-analyses primary scientific literature have largely been specific either freshwater, marine terrestrial ecology, ecotoxicology. In this cross-disciplinary study, we review state knowledge within among these...
Microplastics are an emerging pollutant of high concern, with their prevalence in the environment linked to adverse impacts on aquatic organisms. However, our knowledge these freshwater species is rudimentary, and there almost no research directly testing how effects can change under ongoing future climate warming. Given potential for multiple stressors interact nature, combined microplastics environmental temperature requires urgent attention. Thus, we experimentally manipulated...
Abstract Warming can have profound impacts on ecological communities. However, explorations of how differences in biogeography and productivity might reshape the effect warming been limited to theoretical or proxy-based approaches: for instance, studies latitudinal temperature gradients are often conflated with other drivers (e.g., species richness). Here, we overcome these limitations by using local geothermal across multiple high-latitude stream ecosystems. Each suite streams (6-11 warmed...
As the climate warms, there is little doubt that ecosystems of future will look different from those we see today. However, community responses to warming in field are poorly understood. We examined effects field‐based on intertidal communities Salish Sea, which a regional thermal ‘hot spot’ and therefore model system for studying thermally stressed communities. manipulated temperature at three tidal heights by deploying black‐ white‐bordered settlement plates. Black plates increased situ...
Abstract Global warming over the next century is likely to alter energy demands of consumers and thus strengths their interactions with resources. The subsequent cascading effects on population biomasses could have profound food web stability. One key mechanism by which organisms can cope a changing environment phenotypic plasticity, such as acclimation warmer conditions through reversible changes in physiology. Here, we measured metabolic rates functional responses laboratory experiments...
Abstract Organisms have the capacity to alter their physiological response warming through acclimation or adaptation, but consequence of this metabolic plasticity for energy flow food webs is currently unknown, and a generalisable framework does not exist modelling its ecosystem-level effects. Here, using temperature-controlled experiments on stream invertebrates from natural thermal gradient, we show that ability organisms raise rate following chronic exposure decreases with increasing body...
By maintaining interaction webs in the face of warming, herbivores dampen effects warming on succession and stability.
Ecological studies of global warming impacts have many constraints. Organisms are often exposed to higher temperatures for short periods time, probably underestimating their ability acclimate or adapt relative slower but real rates warming. Many also focus on a limited number traits and miss the multifaceted effects that may organisms, from physiology behaviour. exhibit different movement traits, some which primarily driven by metabolic processes others decision-making, should influence...
Abstract Global warming is one of the greatest threats to persistence populations: increased metabolic demands should strengthen pairwise species interactions, which could destabilize food webs at higher organizational levels. Quantifying temperature dependence consumer–resource interactions thus essential for predicting ecological responses warming. We explored feeding between different predator–prey pairs in controlled‐temperature chambers and a system naturally heated streams. found...
Abstract Warming alters ecosystems through direct physiological effects on organisms and indirect via biotic interactions, but their relative impacts in the wild are unknown due to difficulty warming natural environments. Here we bridge this gap by embedding manipulative field experiments within a stream temperature gradient test whether apex fish predators have interactive freshwater ecosystems. Fish exerted cascading algal production microbial decomposition both green brown pathways food...
Quantifying species interaction strengths enhances prediction of community dynamics, but variability in the strength interactions space and time complicates accurate prediction. Interaction can vary response to density, indirect effects, priority effects or a changing environment, mechanism(s) causing direction magnitudes change are often unclear. We designed an experiment characterize how environmental factors influence between sessile species. estimated per capita non-trophic barnacles (...

Abstract Metabolic rate, the rate of energy use, underpins key ecological traits organisms, from development and locomotion to interaction rates between individuals. In a warming world, temperature-dependence metabolic is anticipated shift predator-prey dynamics. Yet, there little real-world evidence on effects trophic interactions. We measured respiration aquatic larvae three insect species populations experiencing natural temperature gradient in large-scale mesocosm experiment. Using...
