International Journal of Ecosystem

The International Journal of Ecosystem (IJE) is a peer-reviewed journal publishes papers from original research in all areas of ecosystem structure and function as impacted by the changes in climate and land and water use and management practices in a given environment. In the aforementioned context the characterization of ecosystem structural components as community of plants, animals and smaller organisms that live, feed, reproduce and how they interact with each other in the same area or environment, their interdependency are essential for the improved understanding of the functioning of the structural components. The modifications in the structural components as impacted by human imposed changes and/or linked to climate changes are poorly understood and/or are not recorded after rigorous review. In aforementioned context the IJE provides a forum for discussion in the modifications in ecosystem structural components and the associated functions around the world, particularly from developing countries, aimed at the sustainable use of natural resources. Critical review articles are also welcome.
