Interactive effects of intrinsic and extrinsic factors on metabolic rate

Philosophical Transactions of the Royal Society B Biological Sciences, Год журнала: 2024, Номер 379(1896)

Опубликована: Янв. 8, 2024

Metabolism energizes all biological processes, and its tempo may importantly influence the ecological success evolutionary fitness of organisms. Therefore, understanding broad variation in metabolic rate that exists across living world is a fundamental challenge biology. To further development more reliable holistic picture causes this variation, we review several examples how various intrinsic (biological) extrinsic (environmental) factors (including body size, cell activity level, temperature, predation other diverse genetic, cellular, morphological, physiological, behavioural influences) can interactively affect synergistic or antagonistic ways. Most interactive effects have been documented involve temperature both, but future research reveal additional ‘hub factors’. Our highlights complex, intimate inter-relationships between physiology ecology, knowledge which shed light on problems both disciplines, including physiological adaptations, life histories, niches organism-environment interactions ecosystems. We also discuss theoretical practical implications provide suggestions for research, system analyses at hierarchical levels organization focus proximate (functional) ultimate (evolutionary) causal networks.

The seasonal response of metabolic rate to projected climate change scenarios in aquatic amphipods

Journal of Thermal Biology, Год журнала: 2024, Номер 124, С. 103941 - 103941

The responses of organisms to climate change are mediated primarily by its impact on their metabolic rates, which, in turn, drive various biological and ecological processes. Although there have been numerous seminal studies the sensitivity rate temperature, little is empirically known about how this responds seasonal temperature ranges beyond under conservative IPCC scenarios. Here, we measured SMR aquatic amphipod, Gammarus insensibilis, which served as our subject species, with body masses ranging from 0.20 7.74 mg ash free weight. We assessed response across nine levels 12 30.2 °C. These temperatures match norms, an incremental increase 0.6-1.2 °C above each baseline, projected for years 2040 2100 modest Overall, findings showed that effect varies mass, indicated a negative size-temperature interaction, larger conspecifics exhibiting less changes than smaller ones.

Individual energetics scale up to community coexistence: Movement, metabolism and biodiversity dynamics in fragmented landscapes

Journal of Animal Ecology, Год журнала: 2024, Номер 93(8), С. 1065 - 1077

Опубликована: Июнь 26, 2024

Abstract Unravelling the intricate mechanisms that govern community coexistence remains a daunting challenge, particularly amidst ongoing environmental change. Individual physiology and metabolism are often studied to understand response of individual animals However, this perspective is currently largely lacking in ecology. We argue integration into theory can offer new insights coexistence. present first individual‐based metabolic model for terrestrial mammal simulate energy dynamics home range behaviour different environments. Using model, we investigate how ecologically similar species coexist maintain their balance under food competition. Only if individuals able incoming outgoing over long‐term will they be coexist. After thoroughly testing validating against real‐world patterns such as field rates, applied it case study scenarios habitat fragmentation ‐ widely discussed topic biodiversity research. First, comparing single‐species simulations with simulations, find effect on populations strongly context‐dependent. While living alone landscape were mostly positively affected by fragmentation, diversity was highest medium scenarios. Under reproductive investment also most among species. therefore suggest similarity promotes energetics should part ecology theory, relative energetic status reveal why what conditions likely occur. As result, landscapes potentially protected designed maximize The presented here promising tool other change or communities further disentangle global effects preserve biodiversity.

Metabolic rate and climate change across latitudes: evidence of mass-dependent responses in aquatic amphipods

Journal of Experimental Biology, Год журнала: 2022, Номер 225(22)

ABSTRACT Predictions of individual responses to climate change are often based on the assumption that temperature affects metabolism individuals independently their body mass. However, empirical evidence indicates interactive effects exist. Here, we investigated response standard metabolic rate (SMR) annual range and forecasted rises 0.6–1.2°C above current maxima, under conservative scenario IPCC RCP2.6. As a model organism, used amphipod Gammarus insensibilis, collected across latitudes along western coast Adriatic Sea down southernmost limit species' distributional range, with varying in mass (0.4–13.57 mg). Overall, found effect SMR is dependent. Within mass-specific small/young increased at greater (activation energy: E=0.48 eV) than large/old (E=0.29 eV), higher level for high-latitude low-latitude populations. conditions, large responded differently latitudes. Unlike higher-latitude population, whose all size classes, lower-latitude populations, this increase was not seen individuals. The larger/older conspecifics lower could therefore be first experience negative impacts warming metabolism-related processes. Although ecological collapse such basic trophic (aquatic amphipods) owing would have profound consequences population ecology, risk significantly mitigated by phenotypic genotypic adaptation.

Going across taxa in functional ecology: Review and perspectives of an emerging field

Functional Ecology, Год журнала: 2023, Номер 37(12), С. 3091 - 3110

Опубликована: Окт. 19, 2023

Abstract The emergence of functional ecology has changed the focus ecological research from investigating patterns species diversity to understanding how traits relate specific processes generating these patterns. Traits, and can be shared driven by distantly related taxonomic groups. Crossing boundaries among groups is still a challenge critical knowledge frontier in ecology. A cross‐taxa approach, merging trait data across groups, could fill this gap. In context, functionally analogous traits, that may have distinct ontogenetic origins yet represent similar processes, comprise an important recent advance However, which taxa (be them or not) been used with multiple taxa, whether (and how) combined, needs elucidated. We reviewed articles published last 75 years investigate use involving taxa. Our search returned 1006 articles, subset 96 was filtered for extraction.

Abstract Unveiling the intricate relationships between animal movement ecology, feeding behavior, and internal energy budgeting is crucial for a comprehensive understanding of ecosystem functioning, especially on coral reefs under significant anthropogenic stress. Here, herbivorous fishes play vital role as mediators algae growth recruitment.
