    Ecological observations on the Indian Spiny-tailed Lizard Saara hardwickii (Gray, 1827) (Reptilia: Squamata: Agamidae) in Tal Chhapar Wildlife Sanctuary, Rajasthan, India
    Type
    Journal Article
    Description
    Observations on the Indian Spiny-tailed Lizard Saara hardwickii (Gray, 1827) were undertaken in Tal Chhapar Wildlife Sanctuary, Rajasthan, India during the monsoons (July) following quadrat sampling that was time-constrained. The study revealed that the area is one of the preferable habitats for the species. A population analysis showed that the relative abundance of the subadults was higher, followed by juveniles and adults during the study period. The beginning of activity of the lizards was found to vary over the study period depending on prevailing weather conditions. The activity pattern was bimodal, except across rain events. The study revealed two important ecological findings about these lizards; complete sealing of burrow during rains which differed from partial sealing on normal days and complete diurnal cycle of body colour changes during the monsoon. Feeding was the predominant activity of this lizard followed by basking, resting and chasing each other. The adult lizards were found to be strictly herbivorous, in spite of an abundance of insects available in the area during the period. Subadults and juveniles were found to eat both plant parts, as well as insects. Microhabitat use such as inside grass clumps was found to be higher followed by barren ground, under shade and on stones.

  • Title
    Bionomics of a lesser known goby, Stenogobius gymnopomus (Bleeker, 1853) (Perciformes: Gobiidae) from southern Kerala, India
    Type
    Journal Article
    Description
    The biology of a lesser known goby, Stenogobius gymnopomus was studied from the freshwater systems of southern Kerala. Dietary analysis showed that S. gymnopomus is a euryphagous feeder and an omnivore. Cladocerans, together with fish eggs and scales, constituted the major food items. The minimum size at first maturity for male S. gymnopomus is 78mm and for females 72mm. This species was found to be a batch spawner with a prolonged spawning season extending from August to December. Fecundity ranged from 46,323 to 61,291 eggs. Sex ratios revealed that local populations of S. gymnopomus are male dominated.
