Abstract Zooplankton are major consumers of phytoplankton primary production in marine ecosystems. As such, they represent a critical link for energy and matter transfer between bacterioplankton to higher trophic levels play an important role global biogeochemical cycles. In this Review, we discuss key responses zooplankton ocean warming, including shifts phenology, range, body size, assess the implications biological carbon pump interactions with levels. Our synthesis highlights knowledge gaps geographic monitoring coverage that need be urgently addressed. We also integrated sampling approach combines traditional novel techniques improve observation benefit populations modelling future scenarios under changes.

Abstract Purpose of Review Global warming and pollution are among the five major causes global biodiversity loss, particularly in aquatic invertebrates which highly diverse but understudied. In this review, we highlight advancements current environmental studies investigating interactive effects between contaminants freshwater marine invertebrates. We not only focused on temperate regions also synthesized information less studied Arctic/Antarctic tropical regions. Recent Findings general, same combination may result either additive or non-additive depending taxa, response variable, life stage, genotype, exposure level, duration order exposure, number exposed generations. For traditional such as metals pesticides, combined with at individual level were generally synergistic. Growing evidence suggests that multigenerational can shift interaction toward antagonism, while contemporary evolution change type. Summary Our synthesis highlights importance temporal aspects shaping type, including ontogenetic effects, transgenerational evolution. The laboratory experiments (to advance mechanistic understanding) outdoor mesocosm field observations increase realism) is needed to obtain comprehensive assessments pollutants from genes ecosystems.

Loss of transcriptional plasticity but sustained adaptive capacity after adaptation to global change conditions in a marine copepod

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: March 3, 2022

Abstract Adaptive evolution and phenotypic plasticity will fuel resilience in the geologically unprecedented warming acidification of earth’s oceans, however, we have much to learn about interactions costs these mechanisms resilience. Here, using 20 generations experimental followed by three reciprocal transplants, investigated relationship between adaptation marine copepod, Acartia tonsa , future global change conditions (high temperature high CO 2 ). We found parallel genes related stress response, gene expression regulation, actin developmental processes, energy production. However, transplantation showed that resulted a loss transcriptional plasticity, reduced fecundity, population growth when change-adapted animals were returned ambient or reared low food conditions. after successive transplant generations, able match ambient-adaptive profile. Concurrent changes allele frequencies erosion nucleotide diversity suggest this recovery occurred via back ancestral These results demonstrate while facilitated initial survival conditions, it eroded as populations adapted, limiting new stressors previously benign environments.

Steeper size spectra with decreasing phytoplankton biomass indicate strong trophic amplification and future fish declines

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Jan. 9, 2024

Abstract Under climate change, model ensembles suggest that declines in phytoplankton biomass amplify into greater reductions at higher trophic levels, with serious implications for fisheries and carbon storage. However, the extent mechanisms of this amplification vary greatly among models, validation is problematic. In situ size spectra offer a novel alternative, comparing small larger organisms to quantify net efficiency energy transfer through natural food webs are already challenged multiple change stressors. Our global compilation pelagic spectrum slopes supports empirically, independently from simulations. Thus, even modest (16%) decline century would magnify 38% supportable fish within intensively-fished mid-latitude ocean. We also show stems not thermal controls on consumers, but mainly temperature or nutrient structure baseline web. The lack evidence direct effects contrasts most current thinking, based often more acute stress experiments shorter-timescale responses. synthesis integrates these short-term dynamics, revealing acclimating adapting climatic

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

Proceedings of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 292(2042)

Published: March 1, 2025

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.

Epigenetic plasticity enables copepods to cope with ocean acidification

Nature Climate Change, Journal Year: 2022, Volume and Issue: 12(10), P. 918 - 927

Published: Sept. 29, 2022

Abstract Plasticity enhances species fitness and survival under climate change. Ocean acidification poses a potential threat to copepods, major zooplankton group that serves as key link between the lower higher trophic levels in marine environment, yet mechanisms underlying different adaptive responses remain poorly understood. Here we show although elevated CO 2 can exert negative effects on reproduction of Paracyclopina nana , multigenerational plasticity enable recovery after three generations. By integrating methylome transcriptome with draft genome undertaking DNA methylation treatments, demonstrate vital role epigenetic modifications ocean identify regions associated reproductive resilience. Our results might play an important enhancing copepods failing consider phenotypic could lead overestimation species’ vulnerabilities.
