Human disturbances affect the topology of food webs
https://youtu.be/N4D--Wj3JvM What do galaxies and molecular structures have in common? Or trade between countries, communications on the Internet, and trophic relationships within ecosystems? One answer is that they all involve nodes interconnected by flows of mass and energy. In other words, they are networks. The study of networks has revealed intriguing regularities. For example, it is . . . [ Read More ]
Miguel B. Araujo Lab – Resumo de investigação passada e reflexão sobre investigação futura
Quando um leigo me pergunta sobre o objeto da minha investigação, nem sempre é fácil de explicar numa frase. Na verdade, quem trabalha em biodiversidade trabalha com sistemas complexos. Logo, para entender estes sistemas, para os modelar, para projetar dinâmicas futuras, são diversas as ramificações por onde se estende a investigação. Consciente da dificuldade em sintetizar a diversidade muitos . . . [ Read More ]
Climate determination of trophic structures – A tribute to Alexander von Humboldt

Biogeographic analysis of trophic structures reveals the signature of climate and people
Community trophic structure typical of seasonal tropical climates https://youtu.be/1WwGVnNFJOY In Spanish here Climate determines the arquitectures of trophic structures and human activities simplify them. This is the main conclusion of a study published today in Nature Communications, by Manuel Mendoza and Miguel B. Araújo. Using the geographic distributions and feeding . . . [ Read More ]
Conference: Community Ecology for the 21st Century
Photo by Miguel Araújo (Guys fulvus in Monfrague) Of the many problems confronting society on the veil of the 21st Century, one of the gravest is the likelihood that modern humans may so change the intrincate workings of the earth's ecosystems that they will no longer be able to provide the support that human culture requires for its existence. Yet, our ability to understand and predict the . . . [ Read More ]

Are biotic interactions predictable?
UK grassland trophic web. Artwork from food webs.org Even if serious gaps in knowledge of biodiversity remain, much progress has been made in determining how many different types of organisms exist, what evolutionary relationships connect different lineages to a common ancestor, and where different species are distributed. Much less is known about the types of interactions that exist among . . . [ Read More ]
