Studies revealed that phytoplankton population was dominated by members of Bacillariophyceae, Chlorophycea, Myxophycea and Euglenophycea and Zooplanktons population was dominated by Protozoa, Rotifers, Cladocera and Copepoda. Studies on plankton of Tawi river, was made to assess the pollution of water from January 2022 to December 2022. The qualitative and quantitative evaluation and variations in river water showed high quantity of phytoplankton and zooplankton population throughout the study period and rotifers formed dominated group over other groups of organisms. Further, the study revealed that the water of Tawi river is highly polluted at Trail site-B, Samba Jammu in comparison to Trail site-A Bhaderwah Doda by direct contamination of sewage and other industrial effluents. Conclusions were drawn from the study that the plankton population of Tawi river is highly influenced by the discharge from different industrial effluents in Samba Jammu region (Trail site-B, “S-2”). The shift in the planktonic community structure and dominance of pollution tolerant forms at discharge zone indicated deterioration of water quality in this stretch of the river. The pollution in this stretch of the river emphasizes the fact that water is unfit for consumption and domestic use. The effect of water on human and domestic animals would also be harmful to health.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"31 Suppl","pages":"S22-S29"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147881854","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}

The analysis included eighteen phenotypically superior trees from the Srinagar district, focusing on seed length, seed diameter, 100-seed weight, and kernel percent. Significant variability was observed, with genotype T6 from Rajbagh consistently exhibiting the highest values across all traits. Seed length ranged from 2.57 cm to 3.81 cm, with T6 showing the maximum length (3.81 cm). Seed diameter varied between 1.14 cm and 1.88 cm, with T6 again showing the maximum diameter (1.88 cm). The 100-seed weight ranged from 787.96 g to 902.36 g, with T6 having the highest weight (902.36 g). Kernel percent ranged from 71.48% to 88.12%, with T6 recording the highest percentage (88.12%). The study found genotype T6 to consistently demonstrate superior seed traits, indicating its potential for tree improvement programs. The genotypic coefficient of variation (GCV) for seed length, diameter, 100-seed weight, and kernel percent were approximately 8.94, 15.01, 10.32, and 26.56, respectively. The highest heritability (h²) was observed in 100-seed weight and kernel percent (71.61%), indicating strong genetic control over these traits. This research highlights the importance of understanding seed morphology in relation to genotype variability, providing insights for improving Quercus robur L. under diverse environmental conditions in the Kashmir Valley.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"31 Suppl","pages":"S295-S299"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147899484","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}

Hygienic behavior of Apis mellifera L. and Apis cerana F. were investigated. Both species exhibited differential rate of hygienic behavior in terms of removal of pin pricked capped brood cells. After 24 h the removal of dead brood in A. cerana was significantly higher than that of A.melllifera being 94.00 and 88.00%, respectively. The A. cerana comparatively taken less time in differentiating and removing the dead brood in test colonies than A. mellifera. The differential hygienic behavior of A. melllifera and A. cerana may be due to its genetic factors, environmental factors (Temperature, humidity, comb condition, nectar flow), Chemical factors (Pheromones, dead brood odors, parasitic mite odors) Physical factors (Movements, vibration, light) as well as by interaction between all these factors. Hygienic behavior is considered as an important factor in selection and breeding programs of diseases resistance and would greatly benefit the beekeeping industry if productive, hygienic lines were available commercially.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"31 01","pages":"37-39"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147904620","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}
