Abstract The functioning and richness of marine systems (and biological interactions such as parasitism) are continuously influenced by a changing environment.

Of various factors measured during tropical northern Australia, water temperature salinity changes shown causal variance abundance, with most influential external organisms. As like ocean directly affect parasite–host relationships, this study suggests that assemblages ecological functions they perform likely change considerably over coming decades response its proceeding effects.

Body size reduction is a universal response to warming, but its ecological consequences across biological levels, from individuals ecosystems, remain poorly understood. Most processes scale with body size, and warming-induced changes in can therefore have important consequences. To understand these consequences, we propose unifying, hierarchical framework for the impacts of intraspecific reductions due thermal plasticity that explicitly builds on three key pathways: morphological constraints, bioenergetic constraints surface-to-volume ratio. Using this framework, synthesize at multiple levels organization. We outline how trait-based improve our understanding, detection generalization warming.

Evidence of large‐scale biodiversity degradation in marine ecosystems has been reported worldwide, yet most research focused on few species interest or limited spatiotemporal scales. Here we assessed the spatial and temporal changes taxonomic functional composition fish communities European seas over last 25 years (1994–2019). We then explored how these community were linked to environmental gradients fishing pressure. show that variation is more than two times higher variation, with a marked continuum homogenous pattern composition. The regions warming fastest are experiencing an increasing dominance total abundance r‐strategy (lower age maturity). Conversely, slowly K‐strategy (high trophic level late reproduction). Among considered variables, sea surface temperature, salinity chlorophyll‐a consistently influenced communities' patterns, while bottom temperature oxygen had consistent influence patterns. Changes closely related conditions changes. Our study demonstrates importance integrating community‐level traits across multi‐decadal scales large region better capture understand ecosystem‐wide responses provides different lens dynamics could be used support sustainable fisheries management.

ABSTRACT Aim Ecological state shifts that alter the structure and function of entire ecosystems are a concerning consequence human impact. Yet, when, where why discrete ecological states emerge remains difficult to predict monitor, especially in high‐diversity systems. We sought quantify their drivers through space time most ecologically complex marine ecosystem: tropical coral reefs. Location Worldwide. Time Period 1987–2019. Major Taxa Studied Coral reef communities. Methods Using global dataset 3375 surveys, along with 13 series datasets ranging between 1987 2019, we applied novel double‐dichotomy approach classify reefs into four simplified based on relative contributions corals versus algae benthic cover small‐bodied large‐bodied fishes fish standing stock. then examined considering range spatial predictors tested whether have shifted directionally over time, nature common transitions. Results show geographic, environmental anthropogenic context fundamentally shapes at local scale, which explains disparities among case studies, stakes out critical baseline expectations for regional management efforts. also reveal clear multi‐decadal reefs: systems dominated by reef‐building small‐bodied, planktivorous tend been replaced characterised larger‐bodied fishes. Main Conclusions Our results suggest previously unrecognised transition from harness external subsidies consumers associated structurally live corals, herbivore‐dominated stronger bottom‐up dynamics.

An extensive literature exists on how environmental conditions, especially temperature, impact animal body sizes. However, there remains considerable discrepancies, and misunderstanding, in the key definitions concepts of size used to describe observed impacts across studies. Size can be measured using continuous growth metrics, including von Bertalanffy coefficients, or static 'size' such as population-averaged length mass, average size-at-(arbitrary)-age, size-at-maturity, adult size, asymptotic maximum size. Critically, these are not equivalent, temperature is likely affect each different ways. The use disparate metrics response variables estimated biological scales (individual, population, community) empirical contexts (laboratory, field) has led unnecessary confusion apparent contradictions among practitioners. Here, we review nine common confusions associated with measurement fish other water-breathing ectotherms. We then highlight outstanding knowledge gaps global warming might metrics. Clarifying concepts, definitions, applications measures important it help reconcile divergent findings, target future research, improve our predictions about wild populations.

Warming climate impacts aquatic ectotherms both directly, by altering individual vital rates, and indirectly through environmental feedbacks declines in body size, a phenomenon known as the temperature-size rule (TSR). However, understanding relative importance of these effects shaping community responses to change remains limited. We employ tri-trophic food chain model with size- temperature-dependent rates species interaction strengths explore role direct kinetic temperature TSR on structure along resource productivity gradients. find that structure, including propensity sudden shifts, is primarily driven thermal mismatches between consumer predator species, overshadowing indirect TSR.
