Topic: ecosystems

David George Haskell discusses the evolution and ecological importance of flowering plants. The conversation follows the innovations that enabled their diversification and their relationships with animals and ecosystems.

This panel examines the growing need to account for nature and biodiversity in private-sector decisions. Researchers and business practitioners consider the challenges and opportunities involved, in the context of the IPBES assessment of biodiversity and business. The discussion brings perspectives from biodiversity science, management, financial disclosure, industrial leadership and water infrastructure to the relationship between ecosystems and commercial activity.

David Obura draws on IPBES and other assessments to examine interconnected disruptions affecting biodiversity, climate, economies, societies and governance. The lecture asks how underlying drivers and potential tipping points relate to the international order and what constructive transformations could emerge from present crises. It considers differentiated responsibilities across countries and sectors, pathways that recognise ecosystems as foundations of human wellbeing, and ways to balance nature, economies and social outcomes. Existing multilateral institutions offer starting points, but c

Anne Sverdrup-Thygeson discusses biodiversity loss, human pressures on ecosystems and the broader environmental crisis. Conversation in Norwegian.

It is sometimes said that there are two reasons why physics is so successful as a science. One is that it deals with very simple problems. The other is that it attempts to account only for universal aspects of systems at a desired level of description, with lower level phenomena subsumed into a small number of adjustable parameters. It is a widespread belief that this approach seems unlikely to be useful in biology, which is intimidatingly complex, where “everything has an exception”, and where there are a huge number of undetermined parameters. I will try to argue, nonetheless, that there are

Microbes make up the vast majority of the tree of life. While we know very little about most microbial species, large-scale sequencing is giving us glimpses of the diversity that exists both within species and in ecosystems. The challenge now is to find the patterns in this diversity and understand them. This session features provocative talks on attempts to meet that challenge.
