ABSTRACT The genera Iguana and Ctenosaura belong to the Iguanidae family, and populations of most species of these genera have decreased due to anthropogenic effects. The natural history of most species of this family is poorly known, including Ctenosaura similis. Therefore, this study documents some ecological aspects of the species, such as its feeding habits, and habitat and microhabitat use in a population of Isla Contoy in Quintana Roo, Mexico. The data showed that even though C. similis is distributed throughout the island, individuals more commonly use human construction (buildings) of Parque Nacional Isla Contoy (PNIC) and mangrove areas. Microhabitats most used by all age classes and sexes were rocks and trees. The diet of the species is...

Shrivastava, Atul kumar; Khandelwal, N K; Dubey, R K; guru, prabhat kumar.
Traditionally in Indian agriculture draught animals enables farmers to increase agricultural production and improve the quality of life but in recent decades there has been a trend towards replacing draught animals with farm tractors. There is rapid shift from animal to tractor power but the information about actual declining over the period is very little known. This paper presented results of four phase survey conducted for draught animal and animal powered implement usage in four different locations of central India. The result shows a reduction in range of 76.1 % to 90.2 %, in draught animal population and 58 % to 91 % in animal powered implements. This reduction in animal and animal powered implement shows a huge transformation in Indian agriculture...
