Ants show symbiotic association with particular plants and group of insects which produce suitable nest sites for ants. The study showed the nature of nest and habitat of ant species Meranoplus bicolor, Leptogenys processionalis, Solenopsis geminata, Camponotus compressus, Oecophylla smaragdina, Crematogaster brunnea contemta etc., in Aurangabad, M.S. Materials and Methods: The study was done in Aurangabad city in which the study site is divided in urban and periurban area during two successive years June, 2015 to May, 2017. In urban and peri-urban habitats monthly visits have been arranged, some antʼs specimen was collected from ants nest. Photos have been taken for the observation and study of nest by all out-search methods from study sites. Results: The two ant species Crematogaster brunnea contemta and Oecophylla smaragdina make their nest on trees only. Ant species Solenopsis geminata, Meranoplus bicolor, Camponotus compressus, Leptogenys processionalis prefer to make their nest on ground. Both trees and ground forager ants species are found in urban and periurban habitats. Conclusion: According to preferable habitats ants make their nest, they also modified their internal structure according to their needs in different seasons. Six antʼs species nests are observed in urban and peri-urban habitats of Aurangabad city.

Ants are also called ecosystem engineers due to their specific activities like altering vegetation and soil properties through their nesting and foraging behaviors. Biodiversity of ants was very high and it was dynamically interacting with biotic and abiotic factors. The review summarizes the ant biodiversity pattern according to season, vegetation and disturbance level in particular habitats. The study reported that ant diversity was observed more in summer and rainy season but lower in winter season. Vegetation habitat influenced by climatic change, soil pattern, human impact such as land use, pollution hence ant diversity can change accordingly. According to disturbance habitat the diversity of ant was seen to be more in less and partially disturbed habitat as compared to disturbed habitat.

Radioprotection was evaluated by the ability of Liv 52 to reduce the lethality produced by cobalt-60 gamma radiation. Mice were treated by oral gavage once daily for seven consecutive days with Liv 52 (500 mg/kg body weight) prior to radiation. Male Swiss albino mice were exposed to 1 and 3 Gy of whole-body gamma irradiation in the presence (experimental) and absence (control) of a herbomineral formulation of Liv.52. Quantitative variations in the number of red blood cell count were scored in peripheral blood at various time intervals between on the day of exposure to 28 days. At 1Gy dose, depression in RBC was noticed till 24 hrs, whereas in higher doses until day 3with a sharpness in first 24 hrs. Prior administration of Liv.52 significantly prevented the depletion of RBC count and initiated recovery towards normal at 07 days in experimental animal. The behavior of RBC shows decline on day 1 but start recovering gradually further days. On 3 GY extent of depletion of RBCs observed prominently on 12 hrs after irradiation but in drug treated group shows gradual increase and initiated recovery at day 7. It is noted that liv 52 decreases the direct cell killing against gamma radiation may be due to by increasing the cellular glutathione (GSH) level

These indices were compared in infected and non-infected birds. Cestode infection considerably affected hosts protein metabolism irrespective of the age; however the chances were more pronounced in younger ones. Increased concentration of γ-globulin, modified albumin and circulating immune complexes was observed in plasma of infected host. The experiment demonstrated the most significant changes in the protein metabolism of Gallus gallus domesticus 4-8 days after infestation with cestodes Railletina echinobothrida (Magnin, 1881).
