Linear alkylbenzene sulphonate (LAS), an anionic surfactant, is the most widely used active component in most of the laundry and cleansing (L& C) compounds. Improper and untreated discharges of domestic and industrial efuents, which largely contain adequate amount of LAS, frequently pollute both lentic and lotic aquatic habitats and adversely affect their ecological prole. Both aquatic ora and fauna are concomitantly exposed to xenobiotic stress on account of surfactants which have registered a spurt both in their production and consumption, globally. Fishes are the worst sufferer of detergent pollution as they lie on top of trophic level in an aquatic food chain. Blood values of shes are sensitive indicators of aquatic pollution as is evident by haematological anomalies in the sh Heteropneustes fossilis exposed to sub-lethal fractions, 1/2, 1/3, 1/4 of 96 h LC of LAS along with its 96 h LC .In present studies, haemoglobin (Hb) and absolute 50 50 erythrocyte count (AEC)were recorded with a decreasing while total leukocyte count (TLC) with an increasing trend in a concentration dependent manner in all exposure groups as compared to unexposed control group. The alterations in the above haematological parameters of the sh can, thus, be used as sensitive indicators of contamination of aquatic regimes on account of LAS.

Most of the agricultural Commodities and their products/by products are susceptible to fungal spoilage in different pre-and post harvest conditions. A detail survey of whole sale depots was made to assess the natural contamination of the dietary items for incidence of toxic fungi, in particular, Aspergillus group, well documented for elaborating Ochratoxins. The study was made during Jan. 2012- Dec. 2012. Ochratoxin A. is one of the most abundant food contaminating mycotoxins produced mainly by Aspergillus ochraceous (Petzinger et.al.; 2006) and also by Pernicillum verrucosum. Ochratoxin A has been shown to be nephrotoxic, immunosuppressive, mainly carcinogenic and teratogenic in all experimental animals tested so far according to WHO (1990). In this pretext attempts were made to collect and assess the staple human dietary items for natural incidence of toxic fungi open for sale in whole sale depots. The study provides indirect evidences for many of the human ailments the etiology of which is still obscure and prolonged exposure leads to cancer .

http://pzsi.anveshika.org/proceedings-of-the-zoological-society-of-india/wp-content/uploads/sites/2/2018/02/16-June-17.pdf

·

Collembola, an important group of soil Microarthropods are usually associated with moist habitats, However, some species show an adaptation to ecosystems subject to periodic desiccation. This study examined population structure of collembola communities in its native natural site at Firozabad Soil apterygotes were dominated by collembolans belonging to the families, Isotomidae and Entomobryoidae. The highest density was of Entomobryoidae found during rainy season followed by Isotomidae. However the least population was that of Poduridae and Tomoceridae. The present study establishes a direct effect of high atmospheric temperature and low soil moisture on the population density of these microarthropods and this population is also affected by the soil management practices. These soil microarthropods especially collembola are of great significance for the health of the soil and its fertility. The details have been discussed in this paper.

The effect of Melatonin (MEL) and p-chlorophenyl-alanine (PCPA), a β-adrenergic antagonist on immune and reproductive status was studied during reproductively active phase of Indian Passeriformes Finch, Lonchura punctulata. MEL treatment to these birds showed significant increase in the immune parameters such as spleen weight, blastogenic response of splenocytes, total leukocyte count and lymphocyte count, whereas PCPA treatment showed significant decrease in all these immune parameters. On the other hand the treatment of MEL and PCPA together to the birds showed an increase in immune parameters as compared with control group of birds. Histological observations of the spleen substantiate the data of spleen weight analysis as MEL treatment to the bird increased the splenocytes density in spleen, whereas PCPA treatment to the bird showed depletion of splenocytes in spleen. The results of the present study suggest immune-stimulatory and anti-gonadal effect of the neuro-hormone MEL in this avian species.

Rhesus macaques are exceptionally adapted to coexisting with human and thrive near human settlement in both urban and agricultural areas. There are numerous populations of non-human primates (Macaca mulatta) living in and around the Raj-Gardh fort Dumraon, Buxar but none have been documented. A survey of Raj-Gardh Garrison monkey M. mulatta was carried out and studied its ecology and behavior during January 2013 to December 2014 in Dumraon. Macaque position in the group was observed based on the rank and “central male subgroup” together with two or three oldest males that was observed most dominant. Troop also co-dominant, along with females, their infants and juveniles. The home ranges of this species M. mulatta were observed between .01 to 2.5 km2 in day. Feeding activity was found mostly during morning & evening time and resting between 10 AM to 3 PM when temperature was high. M. mulatta is sexually dimorphic with males and females both have represented separate hierarchies. The rhesus groups were characterized by female philopartry with residue natal group but male dispersal. Mating observed mostly in the month of November to January and infants handled by close female relatives and protected by adult males. In the first few days the infant was carried ventrally by the mother. Loss of natural habitat and increased conflict between human and non-human primates were found to be the major threat for the Raj-Gardh Macaques of the region.

Jharia coalfield is one of the most important coalfields in India. The extraction of this specific coalfield is to obtain prime cocking coal which is the great source of energy. Opencast mining is one of the essential and vital mining method which involves various activities due to which the ecological changes and environmental degradation occur. When opencast mining is done, the soils found on upper most layer get severely damaged due to blasting and drilling etc. The opencast mining causes harmful effects on the insects living in the soils. As the nutrient quality and microbial activities of the soil system get disturbed hence the bio-diversity of soil insects of concerning mining areas gets disturbed badly. The living conditions of many insects get changed. This paper presents the result of the study carried out in mining areas i.e. Lodna and Bastacola of Jharia coalfield. The selected soil insects were collected from five different sites of Lodna and Bastacola for study in mining areas and from Baliapur and Sindri for the study of non-mining areas. The obtained results are very useful to understand the mining impact on selected soil insects.

The changes of reproductive cycle in higher vertebrate mammalian rodent give a reasonable index of its ovarian activity with hormonal synthesis of estrogens and progesterone. In the present work an attempt has been made to study the assessment of different concentration of silk dye effluent on reproductive physiology of female Albino mice, Mus musculus. The reproductive toxicity was observed in 25%, 50%, 75% and 100% concentrations. The silk dye effluent cause significant effect on estrous cycle, copora lutea, implantation site, gestation length, litter count, percent survival of litter count and percent pre Implamentational loss. The control mice exhibited regular estrous cycle of 4-5 days. All the parameters except estrus cycle and gestation length reduced with increase in effluent concentration. When female mice treated with different concentration cause a significant decrease in the number of estrus cycle. The numbers of corpora lutea were significantly reduced from 14-5, implementation site 11-2, litter count 11-1.2 and percent survival of litter count from 95.605% to 32.166 % while the percent pre implantational loss were increased from 10 to 36.744 and gestation lengths increased with the increase in effluent concentration from 19.8 – 21.1 days. The finding indicated that the reproductive fertility and ability severely affected due to the different concentrations of silk dye effluent. The detail report of the investigation is presented in this paper.
