- Description: The published findings on the diatom-inferred condition of a terminal lake in the Murray-Darling Basin were overlooked in favour of a revised unpublished interpretation, without the provision of new evidence or argument, posted on the website of the managing state government. Coauthors of the posted report have responded (Tibby et al. 2020) to the publication (Gell 2020) that outlined the changes made to this interpretation. This reply reaffirms that subtle changes were made to published interpretations and that these were critical in the development of a watering plan for the system. It also illustrates that anecdotal evidence was used selectively but would be a valuable contribution if aligned to known climatic variability. Further, this response corrects the widespread misunderstanding that signatory nations to the Ramsar Convention are obliged to retain listed wetlands in the condition observed at the time of listing. Finally, this response contests the favouring of certain evidence and seeks an approach that reconciles all available evidence, incorporates variability into planning and prepares for future management challenges. © 2020 CSIRO.

- Description: Lake sediments constitute natural archives of past environmental changes. Historically, research has focused mainly on generating regional climate records, but records of human impacts caused by land use and exploitation of freshwater resources are now attracting scientific and management interests. Long-term environmental records are useful to establish ecosystem reference conditions, enabling comparisons with current environments and potentially allowing future trajectories to be more tightly constrained. Here we review the timing and onset of human disturbance in and around inland water ecosystems as revealed through sedimentary archives from around the world. Palaeolimnology provides access to a wealth of information reflecting early human activities and their corresponding aquatic ecological shifts. First human impacts on aquatic systems and their watersheds are highly variable in time and space. Landscape disturbance often constitutes the first anthropogenic signal in palaeolimnological records. While the effects of humans at the landscape level are relatively easily demonstrated, the earliest signals of humaninduced changes in the structure and functioning of aquatic ecosystems need very careful investigation using multiple proxies. Additional studies will improve our understanding of linkages between human settlements, their exploitation of land and water resources, and the downstream effects on continental waters.
