The house sparrow (Passer domesticus) is a widely distributed bird species found throughout the world. Being a species which has close association with humans, they chiefly nest on man-made structures. Here we describe the materials used by the house sparrow for making nests along an urban to rural gradient. For the current study, we selected the Coimbatore to Anaikatty road (State Highway-164), a 27 km inter-state highway, which traverses along an urban core to rural outstretch of Coimbatore. Of the 30 nests observed, 15 nests were from the rural, 8 were from the suburban, and 7 were from the urban areas. The nests had two distinct layers, specifically the structural layer and the inner lining. In the current study, we identified 11 plant species, 2 types of animal matter, and 6 types of anthropogenic matter, including plastic pieces and fine rope. The amount of anthropogenic materials in the nest formation varied along the gradients. The usage of anthropogenic materials was high in urban areas (p<0.05) whereas it did not differ at the sub-urban regions (p>0.05). A gradual decrease in the usage of plant matter towards the urban area was noticed (p<0.05). This study explicitly documents the links between nest material usage along an urban to rural gradient, in a human associated bird. © Penerbit Universiti Sains Malaysia, 2016.

Studying small confined habitat has two fold advantages for ecological research. Firstly, its importance as habitat to a micro-ecosystem, and secondly its applications in experimental research. Tree-hole aquatic habitat is such a habitat having a considerable importance as micro - habitat for numerous significant species, especially for disease spreading invertebrates, which act as model systems as they have tractability and generality at laboratory scale studies. This review highlights profiles of tree-hole aquatic habitats and ecological relationships of its inhabitants supported by experimental evidences in peninsular India.
