The acute bladder snail, Physella acuta (Draparnaud 1805) is globally considered as a highly invasive snail and it is synonymised to Physa acuta. This species is host to many trematodes causing foodborne diseases in humans. In the present study, P. acuta is recorded for the first time from Kerala state with its first mitochondrial DNA cytochrome c oxidase subunit I gene sequence from India. Twenty...... hiện toàn bộ
Polyphenolics and Energy Content in Phytoplankton: Evidence from a Freshwater Lake
Springer Science and Business Media LLC - Tập 67 - Trang 18-27 - 2013
C. Chattopadhyay
Investigation was carried out in the ancient man-made, shallow, freshwater lake, Lake Krishnasayer, at Burdwan (23°16′N, 87°54′E), India, to note the variations in physico-chemical parameters, nutrients, phytoplankton communities, concentration of phenols and energy content in phytoplanktons during January–December 2006. The lake was represented by 16, 15, 2 and 17 genera of Cyanophyceae, Chloroph...... hiện toàn bộ
Probstmayria bengalensis n.sp. (Cosmocercoidea: Atractidae) in captive Indian one horned rhinoceros (Rhinoceros unicornis) from Alipore Zoological Garden, Calcutta, West Bengal, India
Springer Science and Business Media LLC - Tập 63 - Trang 129-134 - 2010
Sagata Mondal, Buddhadeb Manna
Nematode specimens collected from the faeces of the Indian one horned Rhinoceros (Rhinoceros unicornis) in the Alipore Zoological Garden, Calcutta, India are diagnosed as a new species under genus Probstmayria and named as Probstmayria bengalensis n. sp. The new species is distinguished from the other valid species of the genus in the presence of 3 pairs of postanal papillae and unequal, similar s...... hiện toàn bộ
Ischiodorylaimus istvani, A New Dorylaimid Species (Nematoda) from India with Revised Key to the Species Under Genus Ischiodorylaimus Andrássy, 1969
Springer Science and Business Media LLC - Tập 64 - Trang 40-45 - 2011
Payel Dattaray, Tiasi Jana, Amalendu Chatterjee, Buddhadeb Manna
One new limnetic nematode species Ischiodorylaimus istvani sp. n. belonging to the genus Ischiodorylaimus Andrássy, 1969 described here was collected from the rhizospheric soil of pumpkin (Cucurbita pepo L.) from the district North 24-Paganas, West Bengal, India. The present species is medium in size (♀: 4.7–4.8 mm; ♂: 4.2 mm). Cardia tongue-shaped. Vagina obliquely placed, enclosed in a thick mus...... hiện toàn bộ
Metyrapone, a corticoid inhibitor, induces inverse changes in pineal and adrenal karyomorphology, dynamics and function in mice (Mus musculus)
Springer Science and Business Media LLC - Tập 63 - Trang 99-107 - 2010
Rajasree Bandyopadhyay, Moumita Dasgupta, Subrata Chakraborty
The relationship between pineal and adrenocortical cell morphology, dynamics and function awaits in depth investigation in mammals. In particular, any studies relating these two glands in response to potent adrenocorticoid inhibitor inducing changes in their functional and hormonal relationship appear to be absent. In our present study, we have attempted to investigate the pineal gland and adrenoc...... hiện toàn bộ
Necrophoresis in two Indian ant species, Camponotus compressus (Fabricius) and Diacamma vagans (Smith) (Insecta: Hymenoptera: Formicidae)
Springer Science and Business Media LLC - Tập 63 - Trang 87-91 - 2010
Sarmistha Banik, Sutopa Biswas, Ranajit Karmakar, Ratanlal Brahmachary
Necrophoresis (removal of nest-mate corpses) was studied in two Indian ant species, Camponotus compressus (fam. Formicinae) and Diacamma vagans (fam. Ponerinae), collected from suburbs of Calcutta (now Kolkata), India. Small groups of worker ants were maintained in formicaria in order to study “hard-wired” behaviour patterns in the absence of any stimulus from gynecoids, eggs, larvae etc. C. campo...... hiện toàn bộ

Mites associated with insects of Agri-horticultural importance
Springer Science and Business Media LLC - Tập 63 - Trang 67-71 - 2010
Paulami Sarangi, Himani Biswas, Salil Kumar Gupta, Goutam Kumar Saha
The present note reports for the first time in West Bengal the occurrence of 27 species of mites under 26 genera, 16 families and three orders collected from 25 species of insects. Out of those, 5 are predators, 13 are parasites and remaining 9 are phoretic in habits. A majority of the mites appeared to be unknown species and their descriptions and illustrations will be published elsewhere after c...... hiện toàn bộ
Seasonal histophysiological study of the pineal gland in relation to gonadal and adrenal gland activities in adult domestic pigeon, Columba livia Gmelin
Springer Science and Business Media LLC - Tập 62 - Trang 13-22 - 2009
N. R. Madhu, C. K. Manna
Some aspects of physiology related to the pineal gland in the adult male domestic pigeon, Columba livia Gmelin have been investigated. It was also correlated with the activity of the gonadal and adrenal glands by changing environmental conditions (e.g., seasonal photoperiods, temperature, humidity and rainfall). The maximum daily temperature was noticed in April and minimum in January, 2003. Pinea...... hiện toàn bộ
