While invasive crayfish populations have been linked to declines in water clarity of shallow lakes and wetlands in Asia and Europe, little research has been done on the potential for similar effects of invasive rusty crayfish (Faxonius rusticus) in large temperate lakes of the Midwestern USA. We related F. rusticus abundance in 17 lakes of northern Wisconsin, USA over time (1984‒2018) to measures of lake clarity (chlorophyll a concentration and Secchi disc depth) estimated from remote sensing (Landsat imagery). Contrary to the effects of invasive crayfish in other study systems, we found a weak, positive association between F. rusticus abundance and water clarity. We propose that lake clarity may increase if declines in small fishes caused by F. rusticus lead to population growth of zooplankton and consequent decreases in phytoplankton through a trophic cascade. Alternatively, F. rusticus could be passengers to, rather than drivers of, lake clarity trends, responding positively to increased littoral benthic productivity when lakes are clearer. Future research should aim to determine if F. rusticus causes or responds to changes in water clarity, but should also investigate the impacts of crayfish invasions on water clarity across a greater variety of lentic ecosystems.","PeriodicalId":18079,"journal":{"name":"Limnology","volume":"382 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2021-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138526157","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}

In winter, surface BP along Line 12 (southern transect) was higher than Lines 15 and 17 (central and northern transects) and reflected the water-temperature distribution. Additionally, any nutrients and dissolved organic carbon did not correlate to BP, suggesting water temperature primarily regulated BP in winter. In spring, surface BP was higher at eastern inshore stations, near large agricultural fields, and was correlated with nutrient concentrations rather than water temperature, suggesting that the limitation shifted to nutrient availability. In summer, surface BP at offshore stations along Lines 15 and 17 was notably lower than the other stations, and the horizontal heterogeneity became largest (maximum to minimum BP ratio = 9.5, compared to 2.8 ~ 4.1 in the other seasons). The BP was also positively correlated to nutrient concentrations, especially phosphorus. Surface BP in autumn also showed higher values at eastern stations as well as spring and positively correlated to phosphorus concentration. Additionally, there was a negative relationship between BP and water temperature, suggesting that bacterial growth was enhanced by groundwater seepage at the eastern stations. The results suggest that the horizontal distribution is characterized by a north–south distribution with a temperature gradient in winter, and allochthonous nutrient loading determines horizontal BP variations in the other seasons in this lake.\u0000","PeriodicalId":18079,"journal":{"name":"Limnology","volume":"101 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2021-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138526190","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}

Along a transect from a riverside to the center of mire, dominant vegetation changed in an almost decreasing order of plant height: gallery forest, skunk cabbage, reed, sasa-bamboo, Moliniopsis japonica, and sphagnum, with sporadic appearance of cinnamon fern (Osmunda cinnamomea) with heights of around 100 cm along the way. It was found that these vegetations had different (Ca2+ + Mg2+) concentration in peat interstitial waters and ash content in peat, respectively (p < 0.05), suggesting a close association of the vegetation types with each physicochemical environment. Most of the sites along the transect were found to be ombrotrophic, on the basis of the groundwater tables much higher than the river surface (up to 6.0 m) and SiO2 concentrations in peat interstitial waters (2.4 ± 0.9 mg/L) that were only around one-tenth of that in the river. Nevertheless, the analysis of ash content in peat demonstrated that soil particles had been transported through river overflows to the mire, especially in the cinnamon fern sites, which had ash contents more than 50% in deeper layers (15–20 cm and 20–25 cm). It was found that SiO2, Ca2+, Mg2+, and K+ concentrations in peat interstitial waters were significantly correlated with fine-sand contents in peat sampled at 5–10 cm depth (p < 0.05). In addition, plant heights showed significant positive correlations with both K+ and Ca2+ concentrations (p < 0.05). The results suggest that, in this mire where is mostly ombrotrophic, soil particles derived from flooding would serve as an important mineral source to affect the vegetation type.","PeriodicalId":18079,"journal":{"name":"Limnology","volume":"4 2","pages":""},"PeriodicalIF":1.6,"publicationDate":"2021-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138526185","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}

In this study, the variations in the abundance of functional traits of sedimentary diatoms were evaluated in two lakes (Garças Lake and Patos Lake), from a subtropical floodplain, which present different intensities of influence of dams. Diatom community functional diversity and functional beta decomposed were calculated. A core from each environment was collected and samples of approximately 50 years were used. According to the functional diversity results, the two lakes showed different patterns, with a greater functional variation in Garças Lake. Through functional beta diversity results, the lakes showed similar results. Both showed a reduction in the functional diversity values and substitution of traits, after the 1980s in Garças Lake, and after ~ 2008 in Patos Lake. In these periods, both environments showed dominance of the same functional categories related to high turbulence and lower waters. The results suggest hydrological changes in the two lakes, which may have been driven by dams close to the floodplain.","PeriodicalId":18079,"journal":{"name":"Limnology","volume":"47 5","pages":""},"PeriodicalIF":1.6,"publicationDate":"2021-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138526186","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}
