Asymmetrical evolution of cross inhibition in zooplankton: insights from contrasting phosphorus limitation and salinization exposure sequences

Proceedings of the Royal Society B Biological Sciences, Год журнала: 2025, Номер 292(2042)

Understanding the evolutionary responses of organisms to multiple stressors is crucial for predicting ecological consequences intensified anthropogenic activities. While previous studies have documented effects selection history on organisms' abilities cope with new stressors, impact sequence in which occur outcomes remains less understood. In this study, we examined a metazoan rotifer species two prevalent freshwater stressors: nutrient limitation and increased salinization. We subjected populations distinct histories (salt-adapted, low phosphorus-adapted ancestral clones) reciprocal common garden experiment monitored their population growth rates. Our results revealed an asymmetric response phosphorus (P) salinity. Specifically, adaptation P conditions reduced tolerance salinity, whereas saline did not show such cross-inhibitory effects. Instead, addition moderate concentrations salt enhanced salt-adapted conditions, potentially as consequence evolved cross-tolerance. findings, therefore, underscore importance considering historical stressor regimes improve our understanding predictions organismal also significant implications ecosystem management.

Metrics, scales, and correlates of intraspecific variation in hypoxia tolerance in fishes

Frontiers in Fish Science, Год журнала: 2025, Номер 3

Опубликована: Март 19, 2025

The extent of aquatic hypoxia (low dissolved oxygen) has increased in recent times and now threatens habitats worldwide. Here, we review intraspecific variation tolerance fish on various scales: geographic among populations; genetic strains; due to laboratory acclimation; individuals coming from a given population having similar exposure history. Metrics include the oxygen level below which costs maintenance can no longer be met by uptake environment; time or at surface respiration is conducted; levels lose ability for coordinated movement. There great diversity range its association with potential underlying morphological, physiological, correlates. We advocate greater standardization experimental design, enhanced data reporting, development validation new metrics tolerance. With understanding tolerance, it might possible predict populations, strains, will fare better during hypoxic episodes; mitigate effects low fishes; design breeding protocols enhance fishes.

Social context prevents heat hormetic effects against mutagens during fish development

FEBS Letters, Год журнала: 2025, Номер unknown

Since stress can be transmitted to congeners via social metabolites, it is paramount understand how the context of abiotic influences aquatic organisms' responses global changes. Here, we integrated transcriptomic and phenotypic zebrafish embryos a UV damage/repair assay following scenarios heat stress, its their combination. Heat preceding exposure had hormetic effect through cellular response DNA repair, rescuing and/or protecting from damage. However, experiencing within negated this molecular lowered larval fitness. We discuss basis interindividual chemical transmission animal groups as another layer complexity environmental stressors.

Redox Metabolism During Aerial Exposure of the Sea Urchin Echinometra lucunter: An Ecophysiological Perspective

Animals, Год журнала: 2025, Номер 15(9), С. 1251 - 1251

Опубликована: Апрель 29, 2025

Intertidal organisms experience daily environmental fluctuations, including changes in temperature, UV radiation, and aerial exposure during low tide, requiring physiological strategies for survival. One adaptation is the "preparation oxidative stress" (POS), where antioxidants are upregulated preemptively to mitigate damage. While POS has been documented over 120 species, case of intertidal most studies focus on single stressors under controlled-laboratory conditions. This study investigated sea urchin Echinometra lucunter natural multi-stress Sampling occurred a day (from 5 a.m. noon), analyzing three conditions: submerged (S), aerially exposed 2 h (AE), reimmersed (R). There was ~4 °C temperature increase AE group compared S group, with peak solar radiation reoxygenation. Antioxidant enzyme activity-catalase, glutathione transferase (GST), superoxide dismutase (SOD)-and lipid peroxidation (TBARS) were assessed gonad intestine tissues. GST activity increased by fourfold intestines individuals, while TBARS elevated gonads, no antioxidant upregulation happened. These results suggest that POS-response (increase GST) triggered interaction exposure. research emphasizes critical importance field understanding complex, multi-stressor environments.
