The tests were carried out for one year in 2013–2014 (initial evaluation trial) and then for three years in 2015–2016, 2016–2017, and 2017–2018 (major yield assessment trials). The fourteen patchouli genotypes and one commercial variety (CIM- Samarth) were studied in an RBD design with three replications. A pooled analysis of variance was performed across the environments/years for the eleven economic attributes. The results showed that most of the attributes had significant differences. In all three environments/years, genetic correlations between economic traits played a critical role in genetic improvement, for example, the traits X3-vs-X4, X3-vs-X5, and X4-vs-X5. As a result, according to correlations throughout the selective environments/years, picking these features will be favorable. Furthermore, the heritability in a broad sense (h2BS) was expressed as a percentage. The scores for all ten attributes ranged from 87.13 to 99.25%. The genetic advance over mean (GAM) percent, which ranged from 13.42 to 162.83%, was equally fascinating. The four winning genotypes for essential oil yield, G/PATC-11, G/PATC-1, G/PATC-2, and G/PATC-5, and the lines G/PATC-1, G/PATC-4, G/PATC-9, and G/PATC-11 for patchouli alcohol percent), were explained by biplot analysis as stable and higher-yielding genotypes. The percentage of ar-curcumene in stable genotypes with a distinct fragrance ranged from 8.60 to 8.71% in G/PATC 4, G/PATC 11, G/PATC 14, and G/PATC 1.

The potential for accumulation of heavy metals can occur in gastropods which are bioindicators of the pond environment. In this study, we present data on gastropods abundance and community structure concerning environmental physicochemical factors and heavy metal accumulation. Sampling was carried out in November 2021 at five observation stations spread over three shrimp ponds. The collection of gastropod samples used two methods based on achievement targets. The gastropod ecology index calculated the abundance, diversity (H′) values of heavy metals analyzed, namely Pb, Hg, Cu, and Cd. Wet digestion with an acid solution of HNO₃ and HClO was performed before measuring the concentration on the Atomic Absorption Spectrophotometer (Shimadzu AA-7000). Furthermore, all data on environmental variables were analyzed by principal components analysis (PCA) to determine the leading variable group for each station. A cluster was formed based on the Bray-Curtis similarity analysis. The results of the gastropod ecology index as a bioindicator showed moderate and low diversity (H′) and evenness (J) values, while dominance (D) was high and moderate. From two species analyzed for heavy metals, <em>Nerita violacea</em> and <em>Telescopium telescopium</em> contained Pb, Hg, and Cu concentrations, but no Cd levels were detected, including in water and sediment. Accumulation of heavy metals in shrimp ponds is not only due to the mass movement of tidal water, some of which contribute, namely the location of the inlet and outlet waterways and the position of the land to the main canal source. In general, these results indicate that the environmental conditions of the pond have accumulated heavy metal pollutants, but its whereabouts cannot be ascertained all the time. These results are sufficient to describe the current situation but need further study its impact on aquaculture production.</p></div>","PeriodicalId":7048,"journal":{"name":"Acta Ecologica Sinica","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71726206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used 50 transects, using the roadside point count method between March 2019 and February 2020 and recorded 3927 observations of 35 species belonging to 14 sub-family. To evaluate the effect of predictive variables, i.e., time-of-day, season and landscape features on abundance estimate of each species of raptors, the Generalised Linear Model (GLM) was used. Chi-square test (χ2) was used to assess the relationship between each species abundance and the period of day. The effect of time-of-day bias on abundance estimate was significant in case of Red headed falcon (χ2 = 6.60, <em>p &lt; 0.001</em>), Steppe eagle (χ2 = 7.89, <em>p &lt; 0.001</em>), and Black wing kite (χ2 = 26.46, <em>p &lt; 0.001</em>), while it was not significant for Shikra (χ2 = 0.306, <em>p = 0.97</em>), Long legged buzzard (χ2 = 0.42, <em>p = 0.93</em>) and Pallid harrier (χ2 = 0.115, <em>p = 0.12</em>).
