While governments and natural resource managers grapple with how to respond to climatic changes, many marine-dependent individuals, organisations and communities in fast-changing regions of the world are already adjusting their behaviour to accommodate these. However, we have little information on the nature of such ‘bottom up’ autonomous adaptations. The east coast of Tasmania, Australia, is one of the world’s fastest warming marine regions with extensive climate-driven changes in biodiversity already observed. The region supports a wide range of marine based activities, including production of high value wild catch seafood and aquaculture, and high levels of participation in recreational fishing, with nearly 30% of the population participating annually.  Already, major southward range extensions in the distributions of almost 100 species have been documented, and large contractions in others, including species that form critical habit for many other species. We present and compare examples of autonomous adaptations from marine users of the region to provide insights into factors that may have constrained or facilitated the available range of autonomous adaptation options, and discuss potential interactions with governmental planned adaptations. We aim to support effective adaptation by identifying the suite of changes that marine users are making largely without government or management intervention, i.e. ‘bottom up’ adaptations, to better understand these and their potential interactions with formal adaptation strategies.

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.
