| hypothalamus but not liver retains daily expression of clock genes during hibernation in terai tree frog (polypedates teraiensis). | circadian clock(s) allow an organism to be in synchrony with the surrounding environment and perform daily and seasonal physiological processes, including hibernation, migration, and reproduction. to cope with adverse environmental conditions, organisms have evolved various strategies. insects undergo diapause, while some higher animals either migrate or hibernate/aestivate during unfavorable environmental conditions. hibernation is an energy conservation strategy used to cope with adverse envir ... | 2020 | 32048527 |
| seasonality in terai tree frog (polypedates teraiensis): role of light and temperature in regulation of seasonal breeding. | seasonality is represented as an initiation-termination-reinitiation of any physiological processes. photoperiod is the most predictable environmental cue which organism use to time their daily physiology and seasonal functions. in natural light environmental conditions, day and night components change in terms of duration, intensity and spectrum of light available. in many vertebrate species, daytime light intensity and spectrum of light play a critical role in gonadal recrudescence-regression ... | 2019 | 30580184 |
| morphological and microstructural changes of the oral apparatus in two anuran tadpoles, in regard to ph. | scanning electron microscopy (sem) and light microscopy (lm) of the oral apparatus of polypedates teraiensis and hylarana leptoglossa tadpoles revealed a number of morphological and microstructural alterations in the labial tooth rows, jaw sheaths and marginal papillae on exposure to acidic and alkaline ph. these morphological and microstructural alterations observed in the oral apparatus of the tadpole are discussed in the light of available literature. the significance of the study with refere ... | 2016 | 26774744 |
| hematology of wild caught dubois's tree frog polypedates teraiensis, dubois, 1986 (anura: rhacophoridae). | blood was analyzed from eighty (forty males and forty females) adult individuals of polypedates teraiensis to establish reference ranges for its hematological and serum biochemical parameters. the peripheral blood cells were differentiated as erythrocytes, lymphocytes, eosinophils, neutrophils, monocytes, basophils, and thrombocytes, with similar morphology to other anurans. morphology of blood cells did not vary according to sex. the hematological investigations included morphology and morphome ... | 2014 | 24616633 |
| blood cell profiles of the tadpoles of the dubois's tree frog, polypedates teraiensis dubois, 1986 (anura: rhacophoridae). | the present paper describes a sequential study of the leukocyte profiles and the changes in morphometry and morphology of erythrocytes in the tadpoles of polypedates teraiensis during their development and metamorphosis, that is, transfer from an aquatic mode to a terrestrial mode of life. blood smears of 21 different stages (gosner stage 26 to 46) of tadpoles were investigated. population of erythrocytes was heterogeneous in population represented by various forms (oval, elliptical or rounded c ... | 2012 | 22649312 |
