Methodology: Twelve quantitative traits for yield and yield attributing traits were studied at Agricultural College, Bapatla during Rabi 2021-22 deploying Hayman's five parameter model generation mean analysis in estimating the gene effects in the population (P1, P2, F1, F2 and F3) generated from the cross AKDRMS 21-54 x YH3. Estimated mean effects affirm the existence of significant variation in the traits studied. Significance of either one or both, scales C or D inferred the existence of epistatic interaction for the traits studied. Digenic non-allelic interaction model explained the gene action of the traits studied in the present investigation. Results: The generation mean for all the traits showed the importance of both additive and dominance type of gene effects. Among the epistatic gene effects, the additive x additive gene interaction was reported predominant for shoot length, plant height, flag leaf length, spikelet fertility and flag test weight. The gene interaction is associated with homozygosity, therefore, pedigree method of breeding may be adopted for isolation of desirable lines, while for all other traits, along with grain yield per plant, dominance x dominance gene interaction was found to be pre-dominant. The gene interaction is not fixable, hence, population improvement approaches, would be effective. Interpretation: Dominance x dominance gene interaction was predominant for grain yield per plant and majority of yield component traits studied coupled with duplicate epistasis, infers to takeup population improvement approaches, such as bi-parental mating and recurrent selection, followed by isolation of purelines in later generations for competent improvement.

Methodology: A batch of 50 larvae of Galleria mellonella and Achoria grisella administered with antibiotics (A group) along with larvae not fed with antibiotics (WA group) were exposed to LDPE film. After biodegradation, the weight loss of degraded LDPE film, Scanning Electron Microscopy, Fourier Transform Infrared Spectroscopy, Thermogravimetric Analysis, and Gas Chromatography-Mass Spectroscopy analysis were performed to confirm the plastic biodegradation potential of selected insects. Results: In a and WA groups, the post-biodegradation for a selected species of wax moth exhibited weight loss of 2.763%, 0.789%, 5.403% and 1.481%, respectively. The SEM images revealed that both A and WA groups were capable of LDPE film disintegration. The FTIR of biodegraded film confirmed the deterioration of LDPE by indicating a change in the typical peaks of C−H and H−C−H bonds that points out the biodegradation of polyethylene.Further, the thermogravimetric analysis showed a substantial mass loss in the LDPE flakes consumed by the insects, demonstrating a decline in the thermal stabilities of disintegrated polymers.

Methodology: Nets of dimension 1m × 1m were placed below the tress of both forests and litter was collected at regular intervals per month and brought to the laboratory for separation into the categories like leaf litter, woody litter (bark), miscellaneous (mixed) and twig. Two types of litterfall such as specific litterfall and standing litterfall were calculated. Environmental factors such as maximum and minimum temperature, rainfall, relative humidity, wind speed, solar irradiance, and photosynthetically active radiation (PAR) were studied simultaneously followed by correlation and Principal Component Analysis. Results: Pre-monsoon showed the highest total litterfall (specific litterfall and standing litterfall) in both types of forests. The decomposition quotient was higher in the pristine forest than in the urban forest. The correlation between litterfall components and environmental factors showed that solar irradiance was positively correlated with litterfall dynamics. Interpretation: The work emphasizes the forest management of urban areas impacted by industrialization and urbanization. The anthropogenic causes influence the plant growth and litterfall pattern thereby affecting the decomposition process and soil health.

Microplastics are of two types: primary microplastics, which are inadvertently released into the ecosystem as microbeads, plastic pellets and plastic fibres and secondary microplastics, derived from primary microplastics, when macroplastics get decomposed in the presence of UV light or weathering. Sources of contamination by microplastics can be classified as Terrestrial sources and Aquatic Sources. Microplastics are widespread in diverse ecosystems and are spread in different parts of the world, like India, China, Brazil and Malaysia. Recent studies have revealed the toxic effects of microplastics on various biotic and abiotic components. Microplastics can be completely removed from the soil by microbial biodegradation, most preferably bacteria, actinobacteria and fungi. Bacteria, the recurring group of microbes, can degrade pollutants. Actinobacteria, a commonly occurring Gram-positive bacterium, degrade polymer accumulation. Followed by bacteria, fungi are a major group of microorganisms known to degrade microplastics.

Methodology: Farmer’s field surveys were conducted to explore the suppressive activity of various crop rhizosphere during each winter, October to January (2016-2019). The survey was done in 14 districts of five ACZs in West Bengal (India), and the total surveyed sample size was 511. The S. rolfsii disease incidence (DI%) data of Rabi crop in surveyed areas and sclerotial population, soil suppressive index, FDA hydrolysis, dehydrogenase activity and culturable microbial assay were performed. Results: In this data set (n=511), the foremost soils belonged to no suppressive category (74.47%), followed by slight suppressive category (20.74%). Negligible number of soils belonged to moderate (0.39%) and strong suppressive (0.39%) category.

{"title":"Classifying chemicals into toxicity categories based on LC50 values- Pros and cons","authors":"K. S. Pillai","doi":"10.22438/jeb/44/5/editorial","DOIUrl":"https://doi.org/10.22438/jeb/44/5/editorial","url":null,"abstract":"It is a usual practice to determine LC50 value in acute toxicity studies conducted in aquatic organisms as an initial step to assess the toxicity of chemicals. In regulatory toxicity studies, normally conducted in GLP (Good Laboratory Practice) certified facilities, acute toxicity of chemicals is evaluated in fish, crustacea, and or alga following the methods given in OECD Guidelines. The chemicals are classified into different toxicity categories based on the LC50/EC50 determined from the acute toxicity studies. For calculating LC50 in acute toxicity tests, the methods given in the OECD (2019) Guidelines are Probit or Logit Analysis (Litchfield & Wilcoxon method and Probit Analysis), Spearman-Karber method, the binomial method, the moving average method, and the graphical method. LC50 is the concentration of a substance that causes 50 % mortality in a batch of test organisms (eg. fish). In acute toxicity studies with laboratory animals like rats, mice, rabbits, etc, instead of LC50, the terminology LD50 is used. The procedure for the calculation of both LC50 and LD50 is same. In this article, LC50 and LD50 are written interchangeably. It means if 100 fish are exposed to LC50, theoretically 50 fish would die. In fact, the inventor of LC50 (Trevan, 1927) defined LC50 as the median lethal concentration. Like any other median value, the LC50 is not affected by extreme values of either side. Unfortunately, Trevan was ruthlessly misquoted by the animal ethicists, as they believed that he was responsible for killing millions of animals for determining the median lethal concentration. According to Rowan (1983), the median lethal concentration in animals varies considerably among the species and is affected by environmental factors. Trevan proposed median lethal concentration (LD50) in frogs and rodents for biological standardization of digitalis extract, insulin, and diphtheria toxin when he was working at Wellcome Research Labs, Beckenham (Pillai et al., 2021a). Trevan never promoted sacrificing more animals to determine median lethal concentration. He was aware of the fact that the determination of median lethal concentration is affected by several factors. The 'characteristic' of a dose-response curve proposed by Trevan is species and test substance-specific. However, after Trevan, LD50s were determined in acute toxicity studies to evaluate the effect of a substance, not for the biological standardization of drugs. His intention was to establish a numerical quality control standard to assess batch-to-batch variation, if any, of the therapeutic products of the Wellcome Research Labs. Based on the LC50/EC50 values determined in aquatic toxicity studies, the chemicals are classified into a hazard category. For example, according to United Nations Global Harmonized System (GHS), if the 96 LC50 of a chemical to fish is ≤ 1 mg l-1 , this chemical is classified into hazard category I (GHS, 2019).Though several methods are prescribed in OECD (2019) Guideline","PeriodicalId":15688,"journal":{"name":"Journal of environmental biology","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47357381","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}
