Welcome to the Tobias lab at Imperial College London. We study how species evolve, interact, and regulate ecosystem function, focusing primarily on the world’s birds as a model system, including their role in seed dispersal and insect pest control. Our mission is to find solutions for major challenges facing humanity, including biodiversity conservation, affordable habitat restoration and sustainable food systems.

  • Populations

    We study a wide array of factors influencing variation in populations of organisms, with a focus on speciation and trait diversification.

  • Interactions

    A key goal of our research is to understand how interactions among species drive evolution and determine the structure and functioning of ecological communities.

  • Ecosystems

    We apply insights from biodiversity science to understand and predict the responses of ecosystems to environmental change and to help develop strategies for conservation and sustainable development.

  • The reserach entity

    November 2024 – Rob Barber’s first paper from his PhD was published in PLoS Biology, showing that variation in sexual selection among the world’s birds is best explained by temperature seasonality and associated factors such as diet and migration. This study publishes a companion dataset to AVONET containing open-access sexual selection scores and uncertainty for 10,000+ bird species worldwide – hopefully an important resource for future researchers.

  • The reserach entity

    October 2024 – As a result of a longstanding collaboration with Dr Tom Matthews (Birmingham University) and several other co-authors, our analysis of the scale of anthropogenic bird extinctions and their likely impact on the functioning of ecosystems was published in Science. The findings showed that humans have contributed to the loss of three billion years of evolutionary history and 7% of global functional diversity in birds alone.  Read paper | Read perspective

  • The reserach entity

    July 2024 – In a collaborative study led by Lucas Martins and Jason Tylianakis (University of Canterbury, New Zealand), we used AVONET trait data to show that frugivorous birds have narrower and more optimized niches towards the edge of their geographical ranges. This result, published in Science, has implications for understanding the role of birds in seed dispersal, and the use of traits as metrics of trophic interactions. Read paper | Read overview

  • The reserach entity

    May 2024 – New family-level bird tree tree published in Nature! Along with the rest of the B10K team, we published the results of phylogenomic analyses, based on genomes sequenced from museum specimens of almost all bird families. These analyses help to clarify the early history of the avian radiation – apart from the enigmatic Hoatzin – and align more closely with trait evolution than previous trees. Read paper

  • The reserach entity

    May 2023 – Tom Weeks published his first PhD thesis chapter in Nature Ecology & Evolution: a global analysis combining field survey data from forest fragments and morphological measurements from the AVONET database showing that dispersal ability shaped by climatic seasonality is a key factor determining bird species responses to habitat change, outweighing effects of latitude, historical disturbance and diet.

  • The reserach entity

    January 2023 – We joined forces with Matthias Schleuning and Daniel Garcia to edit a special issue of Functional Ecology focused on animal functional traits. Now published, this contains articles on a range of systems from springtails to crocodiles, along with our editorial summarising current progress and future priorities in trait-based ecology.

  • The reserach entity

    March 2022 – The AVONET bird trait dataset, based largely on collections of 71 museums, is released in Open Access form as the flagship paper in a special issue of Ecology Letters. AVONET contains measurements of over 90,000 individual birds from >99% of the world’s species, along with information on their ecology, life history and biogeography. The rest of the issue showcases current uses of the data in studies of macroevolution, macroecology and conservation biology. Read paper | Read editorial
