Fish as proxies of ecological and environmental change
Great lab collaborative paper - it was led by a couple of the postdocs in the lab (Chris and Zoe) and had 7 PhD students as co-authors!
Human activities have shifted aquatic ecosystems far from prehistoric baseline states. A lack of long-term datasets that describe organisms and their habitats prior to human disturbance hampers the understanding of human-caused impacts. Fish are excellent, and largely underused, proxies that can reveal the degree, direction and scale of shifts in aquatic ecosystems. Time-based data sourced from contemporary, archived and ancient fish samples can improve our understanding of how aquatic ecosystems have changed. This range of biological, ecological and environmental data from fish can allow ecosystem baseline states to be better defined, providing a reference point to establish policy goals for future conservation and exploitation practices.

Historical fishing records and various biological parts of individual fish provide different types of data that can be used as proxies of aquatic baselines.
