Ecosystems present a great diversity worldwide and use various functionalities according to ecological regions. In this new context of variability and climatic changes, these ecosystems undergo notable modifications amplified by domestic uses they are subjected to. Indeed, ecosystems render diverse services to humanity based on their composition and structure, but their levels of tolerance are unknown. The preservation of these ecosystem services requires a clear understanding of their complexity. The role of research is not only to characterise the ecosystems but also to clearly define the tolerable usage levels. Their characterisation proves to be important not only for local populations that use it, but also for the conservation of biodiversity. Hence, the measurement, management and protection of ecosystems needs innovative and diverse methods. For all these reasons, the aim of Diversity of Ecosystems is to bring out a general view on the function of ecosystems, modelling, sampling strategies, invading species, the response of organisms to modifications, carbon dynamics, and mathematical models and theories that can be applied in diverse conditions.
