Environmental impact studies of biodiesel production from Jatropha curcas in india by life cycle assessment
Environmental performance of biodiesel derived from Jatropha curcas seed was studied by life cycle assessment methodology in India. This paper also compares the environmental impact of Jatropha‐based…
Photorefractoriness and its termination in the subtropical house sparrow, Passer domesticus: involvement of circadian rhythm.
Results are consistent with the Bünning hypothesis of coincidence between endogenous photosensitive rhythmicity and environmental photoperiod timing that an endogenous circadian rhythm is involved in the maintenance and termination of photorefractoriness.
Analysis of Policies in Sustaining Sandalwood Resources in India
Sandalwood (Santalum album Linn.) is an important tree species in peninsular India because of its high economic value and is the best endemic tree in the world. Past regulations and policies have…
Photoperiodically Induced Ovarian Growth in the Subtropical House Sparrow (Passer domesticus)
The results conclude that the subtropical house sparrow is photosensitive and light stimulation is a prerequisite to its reproductive activities and the photoperiodic responses of this bird seems to support the Bunning Hypothesis (external coincidence model).
Circadian Aspect of Photoperiodic Time Measurement in a Female House Sparrow, Passer domesticus

Results indicate that photoperio dic time measurement in house sparrows involves an endogenous circadian rhythm, and Plasma levels of estradiol showed a close relation to ovarian growth.
Endogenous circadian rhythm in the photoperiodic ovarian response of the subtropical sparrow, Passer domesticus
Mangrove Associated Molluscs of India
Phylum Mollusca, the second largest of invertebrates, comprises of soft bodied animals. They inhabit very diverse habitats like marine, estuarine, freshwater, terrestrial and arboreal. They play…
Photoperiodic control of ovarian growth in the subtropical house sparrow, Passer domesticus: evidence of an external coincidence system.
The results of these experiments seem to support Bünning - Pittendrigh external coincidence model and birds placed under 8L/16D or DD did not show any ovarian growth.
Impact of Hydroelectric Projects on Bivalve Clams in the SharavathiEstuary of Indian West Coast
The impact of freshwater discharges from upstream hydroelectric projects on estuarine ecology, particularly on commercial bivalves was seldom ever studied, despite the fact that they contribute…
