Vertical migration to reach cooler waters is a suitable strategy for some marine organisms to adapt to ocean warming. Here, we calculate realized Vertical Isotherm Migration rates (VIM, 1980- 2015) to average -6.6+18.8 m decade-1, increasing to a projected average VIM(2006-2100) of -32.3 m decade-1 under a business as usual emission scenario. The seafloor and the depth of the photic layer pose ultimate limits to the habitat compression possible. These limits will be reached by end of this century across much of the ocean leading to a rapid global compression of the 3-D habitat of many marine organisms. Phytoplankton diversity maybe maintained but compressed toward the base of the photic layer while vulnerable, highly productive benthic habitats, especially corals, will have their suitable 3-D habitat rapidly compressed.


Gabriel Jordà is a senior research scientist at the Spanish Institute of Oceanography in Mallorca, Spain (COB-IEO).  His main line of research is the study of marine climate variability with special focus on the interactions with biological processes. That research is mainly based on numerical modelling and on the analysis of climatic databases. In that framework he has developed several observation based products for climate studies on hydrography, sea level and waves. He has worked on a large number of international and national projects and at present he is member of the steering committe of MedCORDEX, HyMEX and CLIVAR-Spain.

Species on the Move

An International Conference Series

The conference brings together scientists and natural resource managers working in the disciplines of global change, biogeography and evolution, and relevant in contexts of natural resource management, biodiversity management and conservation, and theoretical ecology.

Species responses to climate change is a rapidly evolving research field, however, much of our progress is being made in independent research areas: e.g. understanding the process vs responding to the implications, terrestrial vs marine ecosystems, global meta-analyses vs in depth species-specific approaches. This interdisciplinary conference develops connections between these parallel streams, and across temporal and spatial scales.
