Item Study of the Bird Community in Agasthyamalai hills, Western Ghats, Kerala, India(SACON, 2018) Panigrahi, Madhumita; Azeez, P Apatterns of occurrence or distribution and generality of the pattern (Weins 1989, Vellend 2010). A community is structured by wide array of factors, competition, niche availability, spatial heterogeneity, predation, climatic stability, productivity, dispersal, speciation and many more (Hutchinson 1959, Pianka 1966, Vellend 2010). On the other hand, distribution of species may be influenced by species composition, abundance, behaviour, morphology and their association with the environment (Weins 1989). Owing to the complexity of the systems and interactions among them, the study of community ecology is rightly stated by Schoener (1986) as the ‘most tumultuous and alluring of ecology’s subdisciplines’. Studies on avifauna have been playing a pivotal role in addressing intricate questions and testing varied hypotheses relating to community ecology. As widely noted, methodological advances, well-studied taxonomy and natural history, mostly diurnal behaviour and conspicuousness make birds an easy species to studyItem IMPACTS OF WIND FARM ON AVIFAUNA OF SAMAKHIALI REGION, KUTCH, GUJARAT(SACON, 2017) Kumar, S RameshWind energy is one of the most preferred renewable energy across the globe. Although wind energy is widely accepted as a green energy, the impacts of wind farms, especially on wildlife have been reported from different countries over the past two decades. Compared to other taxa, birds and bats get affected mainly due to direct collision with the wind turbines, along with habitat loss & degradation. The collision of birds with turbines is considered as one of the major direct impact, which first came to notice in the late 1980s from USA. The annual bird mortality rate reported by studies across the world varies from 0 to 64 birds per turbine. Studies indicate that many birds tend to avoid areas close to the turbines and some species do not occupy the area even after five years of turbine installation. India is the fourth largest wind energy producer in the world with an installed capacity 27,151 MW as on December 2015 (MNRE, 2016). Moreover, wind energy is the fastest growing renewable energy sector in India with a target of 60 GW by 2022. Available studies on the impact of wind turbines on wildlife are scarce from India and most of the published studies are from Europe and North America. With this background, the present study was conducted in Gujarat, India with the following three major objectives 1) study the avifaunal composition of the area, 2) study the changes in the assemblage of land birds due to wind turbines, and 3) assess the bird mortality risk caused by wind turbines
