How Do Nocturnal Snakes Select Diurnal Retreat Sites ?

Theoretical and empirical studies of habitat selection suggest that reptiles should use ‘‘fixed’’ structural features (perch diameter, vegetation) or light intensity (sun and shade) to select thermally suitable microhabitats. But how do nocturnal species select thermally suitable diurnal retreat sites at night in the absence of visual cues? To investigate this question, we studied habitat selec...

Karyology of four Indian snakes

Cytogenetic studies were carried out on four species of Indian snakes viz Eryx conicus (Family Boidae), Naja naja naja (Family Elapidae), Vipera russelli and Echis carinatus (Family Viperidae) collected from Jammu region (J&K). Both E. conicus and N. n. naja show deviation from typical ophidian karyotype (2n=36), having 2n=34 (16 macroand 18 microchromosomes, NF=42) in E. conicus and 2n=38 (16 ...

Colour constancy in diurnal and nocturnal hawkmoths.

Diurnal and nocturnal hawkmoths have been shown to use colour vision for flower discrimination. Here, we present evidence that the nocturnal hawkmoth Deilephila elpenor and the diurnal hawkmoth Macroglossum stellatarum also have colour constancy. Colour constancy was shown in D. elpenor in two multiple-choice experiments with five different bluish colour patches under white and blue illuminatio...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
