The overall sex ratio (female/male) was 1.03:1, not significantly different from the expected value 1:1. Nevertheless, sex ratio varied with seasons: 1.32:1 in the early stage of the spawning season (March–April), while 0.46:1 in the later stage (July–August). The monthly succession of the average gonadosomatic index (GSI) and percentages of mature individuals co-indicated that T. swinhonis was a spring-summer (March–August) spawner. Further, the bimodal distribution of the size of eggs from one gravid ovary and histological analysis of mature gonads suggested that T. swinhonis was a multiple spawner with indeterminate fecundity and high degree of spawning asynchronicity. The sizes and ages at first maturity for females and males were 84.47 and 81.86 mm, and 1.62 and 1.56 yr, respectively. The batch fecundity (FB) of this species varied in a wide range from 2006 to 73592 eggs per fish with a mean value of 26487.15 ± 2675.61 (S.E.) eggs and increased with the increasing of the gonad weight (WG), eviscerated weight (WE), total length (LT) and age (A). Overall, T. swinhonis in Biandantang (BDT) Lake is characterized by high fecundity and prolonged spawning season, resulting in easy population explosion. Thus, to remove T. swinhonis moderately or release predator fish discreetly to control its population is proposed considering its reproductive characteristics.","PeriodicalId":7903,"journal":{"name":"Annales De Limnologie-international Journal of Limnology","volume":"25 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91154337","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}

Our study is aimed to use diatom metrics developed from different ecoregions for assessing the ecological status of 11 surface waters in the south-east of the Gaziantep catchment (Turkey). Ecological characterizations of the sampling stations were introduced by Trophic Index Turkey (TIT), Trophic Index (TI), and Eutrophication and/or Pollution Index-Diatom (EPI-D). According to TIT and TI, Karkamış Reservoir had a good ecological condition while it had high ecological status based on EPI-D. This good ecological condition was approved by the presence of pollution sensitive species (e.g., Cymbella affinis, Encyonema minutum, E. silesiacum, Cymbopleura amphicephala, and Navicula radiosa) and relatively low nutrients. Kayacık (TIT ranging 3.15–3.23) and Hancağız (TIT = 3.35) reservoirs had poor and bad ecological conditions, respectively. High nutrient, conductivity, and pollution-tolerant species (e.g., Nitzschia amphibia, N. palea, N. umbonata, N. linearis, N. phyllepta, Tryblionella calida, and Pinnularia brebissonii) supported the ecological statuses of the Hancağız and Kayacık reservoirs. The first two axes of canonical correspondence analysis explained 0.943 of relationships between diatom species and explanatory variables. Explanatory variables, e.g., calcium, conductivity, orthophosphate, nitrate, nitrite, sodium, pH, and sulfur, had strong impacts on the distribution of diatom assemblages among the sampling stations. TIT and TI separated ecological statuses of sampling stations in the south-east of the Gaziantep catchment, which correlated well with the evidence of water chemistry and response of diatom assemblages.","PeriodicalId":7903,"journal":{"name":"Annales De Limnologie-international Journal of Limnology","volume":"18 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79070619","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 aim of the research was to define seasonal and spatial changes of phosphorus internal loading from bottom sediments and to compare this with previous years. We also considered changes in the process of P release when the restoration treatments were limited after 3 yr from 3 methods to 1 method. The highest phosphorus release from bottom sediments was found in the profundal zone, where in summer periods it would reach up to 29.2 mgP m−2 day−1. The lowest P release was observed in the littoral zone, down to a depth of 3 m, where it did not exceed 10.0 mgP m−2 day−1. 31% of the whole load of P released from the bottom sediments was originated from this zone. The research showed an increase of phosphorus release in the first years of restoration treatment and a systematic decrease at all stations in the following years.","PeriodicalId":7903,"journal":{"name":"Annales De Limnologie-international Journal of Limnology","volume":"67 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77354571","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}

LH stimulates the synthesis of testosterone, whereas FSH promotes the maturation of follicles and sperm in vertebrates and invertebrates. However, in rotifers, there are no reports of the effects of chronic exposure to these hormones when added to reconstituted culture medium, as a way to study potential adverse effects that might occur in the environment. Therefore, we studied the reproductive effects of the rotifer Brachionus calyciflorus Pallas 1766 using a 4-day reproductive assay. Our results indicate that LH has a significant effect in increasing the production of females, males, and cysts, while FSH had no significant effect compared to control treatment. Additionally, our results indicate that LH exposure resulted in 0.33% of organisms being deformed, whereas FSH exposure resulted in 1.09% of organisms being deformed. Deformations included: (a) abnormal growth of lorica, (b) joined foot-head, (c) deformed anterior spine, and (d) deformed parthenogenetic eggs. The organisms with LH-induced deformations did not reproduce and only lived 48 h after 4 days of exposure, while those with FSH-induced deformities survived 15 days and produced 105 cysts with a hatching percentage of 58.10%. Our goal was to contribute to the knowledge of endocrine systems and endocrine hormones of rotifers, to explain the potential mechanism of endocrine disruption that results in adverse effects in freshwater rotifers.","PeriodicalId":7903,"journal":{"name":"Annales De Limnologie-international Journal of Limnology","volume":"124 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76171677","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}

Salinity in lentic freshwater ecosystems, as a consequence of climatic changes, is rising concern in the scientific community. These alterations affect water quality, the composition and diversity of the aquatic communities. This study aimed to assess the seston quality of two lentic ecosystems, Crestuma reservoir and lake Vela, and evaluate the effects of salinity on food performance of Daphnia magna and Daphnia longispina (isolated from the referred ecosystems). Feeding inhibition tests were used to conduct these two evaluations. Physical and chemical water classification revealed a poor or good ecological potential of the two lentic ecosystems, according to WFD approach. To evaluate seston quality, filtered and unfiltered water samples from the lentic ecosystems were used as treatments. Although only summer samples from Crestuma presented good water quality, the results from the feeding inhibition tests showed that seston from lake Vela presented more nutritional quality. Concerning the assay to evaluate the salinity effect on Daphnia spp., a significant reduction in the filtration rate was observed. The NOEC value was 0.7 g/L NaCl and 0.8 g/L NaCl for D. magna and D. longispina C and V, respectively. The LOEC value was also distinct between species, being 1.0 g/L and 0.9 g/L, respectively. This work allowed to verify that feeding inhibition tests are not sensitive enough for assess the quality of natural waters.

The present study assesses how plankton communities respond to single and mixture treatments of copper sulphate and ammonium nitrate where both agrochemical concentrations are below legal limits. Twenty-five microcosms were used to assess the effects of four treatments (n = 5): (1) low nitrate (L) of 25 mg L−1; (2) high nitrate (H) of 50 mg L−1; (3) copper treatment (CU) of 0.04 mg L−1 of copper; and (4) interaction treatment (I) of 50 mg L−1 of nitrate applied together with 0.04 mg L−1 of copper, and the controls (C). Plankton abundance, phytoplankton biovolume and zooplankton community structure (changes in the diversity and richness) were used as structural endpoints, and oxygen production and litter decomposition as functional indicators. Overall, results show no effect on the plankton community exposed to agrochemical under legal limits in single neither in mixture treatments. Only by the end of the experiment, total zooplankton abundance shows differences between interaction treatment (I) and the rest of the treatments and controls. Concretely, the interaction treatment suggests how a nutrient enhancement from ammonium nitrate addition may counterbalance the toxic effect of copper sulphate on zooplankton, most likely as a result of higher phytoplankton availability that positively influences zooplankter survival. Both drastic and subtle effects on communities are relevant for disentangling how chemicals interact under European current legal limits.","PeriodicalId":7903,"journal":{"name":"Annales De Limnologie-international Journal of Limnology","volume":"40 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75934592","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}

Cluster analysis (CA) was used to group lakes characterised by similar changes of maximum water temperature. The first group included five lakes in which the values of the maximum temperature trends were 0.41 °C dec–1. In the second cluster the average value of maximum water temperature increase was smaller than in the first cluster (0.36 °C dec–1).
