Parental effects, where the phenotype of an individual depends on the environment of its parents, could play an important role in driving population responses to climate change. Furthermore, characteristics of the species and stress exposure could be important for determining the outcome of this plasticity. Using a meta-analysis approach, we investigated the role of parental effects in allowing marine invertebrate species to cope with climate change. We summarized 107 fully-factorial sets of comparisons from 23 peer-reviewed papers that assessed how exposing parents to ambient or stressful conditions influenced responses of offspring exposed to ambient or stressful conditions. We calculated effect sizes (Hedges’ g) for these four contexts of ancestral-progeny experimental environments and collected life history information from the literature for the 20 species included in our study. We conducted subgroup analyses and meta-regressions to assess important characteristics leading to significant parental effects. We found that the level of environmental predictability between parents and offspring determined whether offspring performed better when their parents had also been exposed to stressful conditions representative of climate change. These observed parental effects were significant for species exposed to elevated CO<sub>2</sub> levels that were subtidal, sessile as adults, and had non-feeding larvae (i.e., recruit relatively locally). Understanding links between life stages, including characteristics associated with the strongest links, will aid in evaluating whether adults are likely to prime their offspring for future climates.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"59 2","pages":"509 - 521"},"PeriodicalIF":1.7,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The final size achieved by snails in IT and OT were similar (~ 500 mg) while maximum IR was lower in IT (~ 400 mg/g.d vs ~ 800 mg/g.d of ET). Survival was similar between treatments, but growth parameters fitted by a modified Von Bertalanffy growth function with a temperature dependence on growth coefficient differed.

In contrast, the lowest Shannon diversity (2.161) and species richness (2.009) were recorded at Ezhattumugham. The elevated diversity and richness at Athirappilly, coupled with sensitive taxa belonging to Ephemeroptera, Plecoptera, and Trichoptera, indicate favourable ecological conditions and minimal anthropogenic impact. Conversely, diminished diversity and richness with a lack of sensitive taxa at Ezhattumugham were attributed to deteriorated water quality. A two-way analysis of variance was performed to assess variations in physicochemical parameters between stations and seasons, revealing significant spatial and seasonal variations. Water temperature, electrical conductivity, dissolved oxygen, and biological oxygen demand exhibited statistically significant differences between stations and across seasons. Canonical correspondence analysis elucidated a significant relationship between the distribution and composition of aquatic insects and the water quality variables measured. The pre-monsoon season was characterized by a higher prevalence of tolerant taxa, while the post-monsoon season was distinguished by sensitive taxa, reflecting improved water quality. These patterns highlight the temporal fluctuations in water quality and their impact on aquatic insects. The finding emphasizes the interplay between water quality parameters and biodiversity, offering valuable insight for conservation efforts and sustainable river basin management.</p></div>","PeriodicalId":8262,"journal":{"name":"Aquatic Ecology","volume":"59 2","pages":"487 - 499"},"PeriodicalIF":1.7,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074137","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We investigated temporal and spatial patterns of macroinvertebrate colonisation on macroplastic litters in contrasting stream hydraulic biotopes (riffle, pool, and run) in minimally impacted headwater streams of Eastern Cape, South Africa. Plastic substrates of different proportions of natural and plastic litter were deployed across four sites. The Substrate group included 100% natural substrates (NS), 50% natural material and 50% plastic litters (NP), and 100% plastic (PD) litters.

We observed that NS had significantly higher macroinvertebrate Margalef’s richness, Shannon, and Simpson diversity values than macroplastic substrates in pools. This difference suggests that specific-hydraulic biotope characteristics, such as sediment accretion and stream discharge, influence macroinvertebrate diversities. However, the dominant taxa had a marked presence in all substrate groups within hydraulic biotopes throughout the study, resulting in temporal variance that was not significant.

Stressors, both environmental and human-caused, can affect aquatic community structures. To test this hypothesis, a comprehensive dataset was compiled from various aquatic habitats, including rivers, ponds, reefs, and coastal waters.

Results showed a significant distinction between freshwater and marine communities, with rivers and ponds hosting fewer taxa than marine environments, reflecting unique ecological patterns. In freshwater systems, fish and invertebrate communities are significantly driven by conductivity, temperature, and metals such as arsenic and barium, while diatoms and bacteria are primarily influenced by oxygen levels, atrazine, and perfluorooctanesulfonate. In marine environments, community composition is primarily affected by turbidity and conductivity.
