    Ecology of Indian Rock Python (Python molurus molurus Linn.1758) in Keoladeo National Park, Bharatpur, Rajasthan, India.
    (SACON, 2012) Ramesh, C.; Bhupathy, S.
    Snakes in India are one among the richest assemblages in the world with about 279 species reported so far. However, studies focusing on their ecology are scanty. In tropical ecosystems, it is important to understand ecology of large bodied snakes such as pythons for proposing measures to conserve them. In this context, assessment of the python habitat and understand burrow ecology, population ecology, diurnal activity, food and feeding habits and breeding biology were investigated. The results provided are based on visual observations on free ranging Indian python in Keoladeo National Park (KNP) Bharatpur, Rajasthan, India between October 2007 and April 2010.

    Distribution of select nutrients and metals in the soils of a wetland-terrestrial ecosystems complex: A Case Study of Keoladeo National Park, Bharatpur, India.
    (SACON, 2007) Prusty, Anjan Kumar B.; Azeez, P.A.
    The present study reports the pedological characteristics along the soil profile in a mixed habitat system (woodland. wetland and grassland) with emphasis on selected nutrient elements. alkali and alkaline earth metals, and heavy metals. The main purpose of this study was to examine the distribution pattern of nutrients, alkali and alkaline earth metals and heavy metals on a spatio- temporal scale. Soil samples collected at depths of O, 25, 50, 75 and 100 cm were examined with respect to certain select Physico-chemical parameters following standard methods and was found to differ considerably in their nutrient contents.

    The Diel Activity Pattern of Indian Python (Python molurus molurus linn) at Keoladeo National Park and Some Factors Influencing it
    (Wildlife Institute of India, Dehradun, 1991) Bhatt, Karamvir; Choudhury, B.C.
    This study investigated die] activity pattern of Indian python (Python moJurus molurus Linn) at Keoladeo National Park Bharatpur. The study was conducted in an intensive study area of 0.5 Sq Km selected after pre sampling survey in the park. The methodology involved to estimate activity pattern of pythons was monitoring of a permanent transect every four hours, on diel basis, to record python’s tracks and sightings. The diel variations in temperature, humidity, burrow microclimate, prey activity and prey abundance were also quantified along with diel activity pattern of python. Results show a shift in diel activity pattern with seasons. The activity pattern of pythons was diurnal in winter, uniform throughout spring and bimodal crepuscular in summer. There was no significant correlation between python activity and other factors quantified, though temperature and humidity affected the diel activity pattern considerably. The microclimate variation gradient existing between outside and inside burrow possibly play an important role in occupation of the burrow and this in time influence the surface diel activity pattern. The shift in the diel activity is attributed to seasonal change in the abiotic factors. No relationship between prey abundance and activity pattern could be established possibly because python’s ability to go with out food during the cool season. Other factors not quantified during this study like reproductive behavior, body size and biotic disturbances are suspected to be responsible for the observed diel activity pattern of pythons. It is concluded that the diel activity pattern of pythons in KNP is not influenced by just one factor but is a manifestation of a combination of various abiotic, biotic and endogenous factors. A temperature sensitive telemetry study would help further in investigating the ecological aspects of this cryptic species.

    Ecological separation of four sympatric carnivores in Keoladeo Ghana National Park, Bharatpur, Rajasthan, India
    (Wildlife Institute of India, Dehradun, 1989) Mukherjee, Shomita; Johnsingh, A.J.T.
    The study conducted from 5th May 1989 to 9th October 1989 covering summer and monsoon looked at the ecological separation of four sympatric carnivores in Keoladeo National Park, Bharatpur, Rajasthan. The four carnivores were - Jungle cat (Felis chaus), Fishing cat (Felis viverrina), Jackal (Canis aureus) and otter (Dutra perspicillata). Objectives of the study were to determine differences in dietary composition, habitat occupancy and time of activity as well as to tryout methods for studying sympatric lesser carnivores. Five methods were tried out to obtain these Objectives. Line transects and searches during mornings and nights were used to collect data on prey abundance, location of carnivores and their tine of activity. Scats were collected and analyzed to determine dietary composition and see how they differed among jackal, fishing cat and Jungle cat. Otter spraints were not found. The following conclusions are although some amount of overlap is evident an overall difference in habitat use, time of activity and dietary composition is seen. Jackals and Jungle cats are habitat generalists but dietary specialists. "The fishing cat and otter are habitat as well as dietary specialists . Jungle cat and fishhing cat are largely nocturnal Out the Jackal and otter are active throughout the day. Behavioural observations added to the results obtained from the other methods . 100 methods however were found unsuitable for studying lesser carnivores.
