CLIMATE CHANGE IMPACT AT THREE DIFFERENT SCALES OF BIOLOGICAL DIVERSITY: A HOLISTIC REVIEW OF RESEARCH FINDINGS FROM ACROSS THE GLOBE

Impact of recent changes in global climate is evident through many scientific investigations using field observations and through modelling studies. The impacts are perceived to effect biodiversity at three different scales i.e. ecosystem diversity, species diversity and genetic diversity. Most findings indicate a notable widespread impact on tropical region and specific effects on some habitat specialists and species with no migration ability. The current review also highlights the need of more research efforts to investigate impact on genetic diversity across various taxa of flora and fauna.
