Hydrosere Succession Model of Marshy Wetland Mediated Nesting Behavior of Sarus Crane, Grus antigone antigone (Aves: Guridae)
Journal Title: Bulletin of Pure and Applied Sciences Sec. A-Zoology - Year 2018, Vol 37, Issue 1
Abstract
The hydrosere succession is not a new to ecology, but succession mediated by sarus crane, Grus antigone antigone (Aves: Guridae) nesting was observed earlier than natural wetland succession. The sarus crane nest is weird to its large size and heavy inundated body mass. These nests were constructed inside marshy wetland during rainy seasons and have conservative values. Observations made during investigation that it was also contributed ecological succession to the wetlands. Eleven out of sixteen nests found at the margin of reservoir and in marshy landscape. This was reflected that this island like platform of sarus nest turned into land having pioneered land plant (grasses) stagnant and de-floating stage, reed swamp stage and sedge stage. The nest mediated succession is cooperatively very shorter than a natural hydrosere succession. Therefore, on the basis of contemporary survey and findings authors suppose to propose it as a hydrosere succession and can be a model or representation in ecological biology of nesting by sarus crane. Moreover, it facilitates the conservation of threatened species in adverse climatic condition and it is an outstanding way of ethological acclimatization of this unique bird for livelihood and sustainability.
