Palestra "How can so many species coexist? An exploration of space and ecological interactions"
Os investigadores da Cátedra Rui Nabeiro Biodiversidade – MED – Universidade de Évora promovem no dia 4 de abril a próxima sessão da iniciativa “The Alfred Wallace Seminar Series” dedicada a discutir temas relacionados com biodiversidade e funcionalidade dos ecossistemas.
Neste dia a palestra será proferida por David García-Callejas (University of Canterbury) com o tema “How can so many species coexist? An exploration of space and ecological interactions“ . O evento acontece pelas 14h do dia 4 de abril através da plataforma ZOOM (Link AQUI).
Resumo: Understanding how multiple species coexist in natural communities is, despite the apparent simplicity of the question, astonishingly complex. Theory predicts that when resources are limited, dominant species will end up out-competing others, severely limiting biodiversity. Therefore, ecologists predict that there exist mechanisms in natural communities for preventing this dominance, allowing species to differentiate from one another in different dimensions. I will discuss, based on theory and observations from a species-rich Mediterranean grassland, how two factors can help understand the local coexistence of multiple species: the different types of interactions in which species engage, and the spatial dimension of these interactions.
