We aimed to assess the effects of simulated climate warming (4.5 °C) on the functional trait responses of a submerged macrophyte, <em>Stuckenia pectinata</em> (L.) Börner, in a synchronized oligohaline (4 ppt salinity) mesocosm experiment conducted in two different climate regions in Turkey: cold semi-arid Ankara and hot, dry Mediterranean Mersin. The experiment was conducted using eight mesocosms at each site, with four replicates of each ambient temperature and warming treatment. Each mesocosm held 5000 L and was inoculated with natural sediment, plankton, macroinvertebrate and fish communities to represent natural oligohaline lake ecosystem. <em>S. pectinata</em> shoots collected from a single population from a coastal lake in Mersin were also inoculated in all mesocosms in similar abundances. Overall, we observed significant differences in macrophyte functional traits between the two sites with different climates, albeit with less pronounced effects of a 4.5 ºC rise in temperature within each site. Specifically, higher macrophyte percent volume infested (PVI) and canopy height were observed in the warmer Mersin than in the colder Ankara, which we attributed to higher shading by phytoplankton (reflected by water column Chlorophyll a, Chl-a). The biomass ratio (%dry weight (DW)/wet weight (WW)) was notably higher in Ankara, suggesting that the macrophytes in Ankara acquired relatively more resources than those in Mersin. The pronounced differences between the two sites likely reflected not only temperature differences but also cascading ecosystem characteristics (e.g., water column Chl-a, water nutrients) due to climatic differences.</div></div>","PeriodicalId":8273,"journal":{"name":"Aquatic Botany","volume":"198 ","pages":"Article 103855"},"PeriodicalIF":1.9,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143146470","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The assembled chloroplast genomes ranged in size from 195,577 to 201,312 base pairs (bp) and contained annotations for 253 (or 254 in some strains) genes associated with photosynthesis, transcription, biosynthesis and other essential processes.

Here, we studied mineralogy, microstructure, and chemistry of adjacent coralline rhodophyta systems in La Paz Bay: <em>Neogoniolithon trichotomum</em>-dominated tidal pools, and rhodoliths from a shallow rhodolith bed at San Lorenzo channel.

Differences between growth forms and the relationships between ecosystem functioning and environmental conditions can be described by functional traits. Seasonal variation in functional trait expression can lead to alterations in ecosystem functioning. As such, when inferring trait-environment relationships, a species’ functional niche should capture this temporal variation. However, it is unknown how functional traits in macrophytes vary seasonally, and the importance of between-growth form variation. Using hypervolume analysis and linear mixed effect modelling, we demonstrate that seasonal trait variation within-growth forms is stronger than between-growth form variation over time. We found that emergent macrophytes have significantly (p &lt; 0.01) higher specific leaf area in June compared to September. Whereas leaf nutrients (total nitrogen and phosphorus), are significantly higher early in the growing season for emergent, floating rooted, and submerged plants (p &lt; 0.05). We show that the large functional niche of submerged macrophytes is shaped by seasonal variation, and that the functional niches of all macrophyte growth forms overlap, suggesting redundancies in the maintenance of ecosystem functions. Together, this study demonstrates the influence of seasonal variation on macrophyte functional traits. Thus, seasonality is relevant to our understanding of aquatic ecosystem functioning and must be considered when determining the ecological role of macrophytes across a season. This study provides rationale for further examinations of between-growth form redundancies in the ecological role of macrophytes.</div></div>","PeriodicalId":8273,"journal":{"name":"Aquatic Botany","volume":"197 ","pages":"Article 103852"},"PeriodicalIF":1.9,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143170167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using 13 nuclear microsatellite loci, we analyzed genetic diversity and structure of <em>S. pectinata</em> subpopulations along the southeastern shoreline of the main lake and inside Crescent Island Crater, a peripheral lake basin enclosed within the rim of an extinct volcano. Results revealed a predominantly sexual reproductive strategy with limited clonal expansion in the main lake contrasting with pronounced clonal growth in the crater basin. Each subpopulation experienced recent bottlenecks. Crater basin subpopulations exhibited the strongest divergence, lower clonal diversity and larger-sized clones. We explain this differentiation by the exposed crater rim acting as barrier, isolating the crater basin from the main lake during recent decades when low water levels prevailed, accompanied with less negative impact from alien species than in the main lake. Clonal extension occurred on steep-sloping hard sandy substrates, that likely prompted local reproductive adaptations.
