Short summary
Short summary
We studied ostracod assemblages from an 1800-year sediment record from a Jamaican lake to evaluate causes of change and to test a previous interpretation from a Late Pleistocene record, which suggested that lake-level change was the main control. We found that, rather than being a simple response to changing lake level, ostracod assemblage changes are a complex response to a range of factors. Our findings may have relevance to the interpretation of ostracod assemblages in other similar lakes.

Short summary
The Arctic is warming almost four times faster than the global average, placing the numerous lakes at risk from climatic change. In lakes, ostracods (small aquatic crustaceans) can be a major contributor to the biomass and used to track climatic change through time. We characterise current environmental and habitat preferences of Arctic ostracod species to understand current, future and past change. Increasing temperature and nutrients are likely to be significant drivers of ecological change.
