Here, we provide the first insights into PBRs in tintinnid assemblages using 18‐yr data from Jiaozhou Bay, a typical coastal bay in the Yellow Sea. We hypothesized and verified that PBRs vary across contrasting anthropogenic nutrient inputs and that functional and phylogenetic diversity would deliver more information than conventional species richness. High productivity promotes more diversity under low to medium rather than high anthropogenic nutrient inputs. Compared to species richness, functional and phylogenetic diversity reveal more PBR patterns and respond more quickly in response to varying anthropogenic inputs. A concave+ PBR is revealed for functional diversity in the ecozone with highly active water exchange. Our study contributes to the understanding of PBR in marine unicellular secondary producers and their responses to anthropogenic nutrient inputs in coastal ecosystems.","PeriodicalId":18128,"journal":{"name":"Limnology and Oceanography Letters","volume":"64 1","pages":""},"PeriodicalIF":7.8,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143451861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They also represent an important food source for humans since hunter‐gatherer times, which motivates interest in using oyster shells as environmental and life history archives. Still, oysters have often been disregarded in sclerochronology studies, although several methods based on both microtextural and geochemical approaches have successfully been investigated. We review how these methods have been used to improve interpretations of shell records, and we identify knowledge gaps in a variety of disciplines. Those include ecology to study larval dispersal and growth rates; archaeology to determine shell midden constructions and site occupations; and palaeoenvironmental and palaeoclimate reconstructions from tidal to annual timescales. We also suggest standardizing sclerochronology procedures to improve palaeoenvironmental reconstructions and biophysical models on oyster larval dispersal.","PeriodicalId":18128,"journal":{"name":"Limnology and Oceanography Letters","volume":"13 1","pages":""},"PeriodicalIF":7.8,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143056386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detecting loss of resilience within a system can provide early warnings for tipping points. This requires long, regularly spaced time‐series, characteristics that are rare among marine observational and proxy records. Due to their remarkable length and temporal resolution, records from bivalve shells offer a unique opportunity for assessing resilience in the marine environment. Here, we investigate the suitability of bivalve records for measuring changes in two resilience indicators, autocorrelation and variance. We find that increment‐width records typically considered robust can provide reliable resilience assessments. However, while autocorrelation is a generally robust indicator for increment‐width series, variance may exhibit biases mainly associated with age‐related effects. This work provides guidelines for obtaining reliable resilience assessments from bivalve records, unlocking their potential to provide early warnings for tipping points.","PeriodicalId":18128,"journal":{"name":"Limnology and Oceanography Letters","volume":"22 1","pages":""},"PeriodicalIF":7.8,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142940186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The metabolic theory of ecology uses activation energy to assess the sensitivity of biological processes to temperature, but neglects how resource availability might modify temperature sensitivities. To understand the impacts of resource limitation on temperature sensitivities, we performed experiments manipulating temperature and three key resources (nitrogen, phosphorus, and light) in six species of freshwater phytoplankton. We measured activation energies of population growth rates and how they were modulated by resource limitation. We find that the interaction of temperature and resource limitation is dependent on the resource type. Phosphorus limitation did not modify the temperature sensitivity of growth rates, light limitation reduced the sensitivity of growth rates to temperature in all species, and nitrogen limitation had species-dependent effects. We explore how stoichiometry and cell physiology may explain the complex responses of phytoplankton to multiple environmental changes.</p>","PeriodicalId":18128,"journal":{"name":"Limnology and Oceanography Letters","volume":"10 1","pages":"91-100"},"PeriodicalIF":5.1,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/lol2.10453","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142937544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
