Community Ecology has undergone significant transformation in recent years, evolving from a focus on local processes to encompassing metacommunity dynamics, niche and neutral theory, eco-evolutionary dynamics, and the influence of historical and regional factors on biodiversity patterns. This 2nd edition provides an updated and accessible introduction to modern community ecology for advanced undergraduates, graduate students, and researchers. It introduces state-of-the-art concepts while maintaining a reasoned and balanced perspective on unresolved issues in the field. The book covers essential topics such as species interactions, food webs, and ecological networks, offering comprehensive coverage of ecological concepts at the community level.
