Visual representation of a network of co-occurrence and the corresponding network of biotic interactions A new study led by researchers at Miguel B. Araújo Lab has pioneered a method for interpreting the complex network of species interactions within ecosystems. Their findings, published today in Nature Ecology and Evolution, offer a significant breakthrough in ecological research, showcasing a . . . [ Read More ]
Position available: PhD candidate in Community Ecology and Systematic Conservation Planning
Project description Biodiversity is declining at unprecedented rates, with far-reaching consequences for the functioning of ecosystems and human well-being. The loss of any species can have profound consequences given that all species are entangled in complex networks of interactions with other species. Thus, any species loss can promote a deep reorganisation of the communities and ecosystems. . . . [ Read More ]
Building Bridges in Biology Conference
Miguel B. Araújo was invited to give a keynote address to the March 2023 Instituto Gulbenkian de Ciência Conference on Building Bridges in Biology. The conference has a strong focus towards solving health problems but with a broad view, which includes ecosystems and global change. His talk will draw on some of the lab's recent work on trajectories and critical transitions in complex . . . [ Read More ]

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
This is our little tribute to Alexander von Humboldt while disseminating the results of our recent paper in Nature Communications about climate determination of animal community trophic structures. https://youtu.be/1WwGVnNFJOY . . . [ Read More ]
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 ]
