A new issue of the New Zealand Journal of Marine and Freshwater Research pays tribute to one of New Zealand’s eminent freshwater scientists, Dr John Quinn, who sadly passed away in November 2018. John spent his career as an applied scientist, science leader and mentor. His research has had a significant impact on the understanding of freshwater issues across the globe.
From 2015 to 2018, John was NIWA’s Chief Scientist – Freshwater and Estuaries. Among other accolades, John was awarded the New Zealand Freshwater Sciences Society Medal of Excellence in 2018 for outstanding contributions to freshwater science. In his career, he contributed to and led research programmes across a wide range of freshwater issues, including integrated catchment management, ecological restoration, and land-use effects on freshwater ecosystems. John had an international reputation for long-term studies that have highlighted human impacts on freshwater ecosystems.
The papers in this issue address one of John’s areas of expertise: the effects of land-use on aquatic ecosystems. These interactions produce some of the most complex problems for environmental science and management in Aotearoa. The 13 papers in this issue represent a wide range of approaches for assessing land-use effects.
This special issue is a modest way to express the appreciation held for John by his colleagues in freshwater science.
