Quaternary palaeoenvironmental proxies and processes − papers in honour of Professor Alayne Street‐Perrott

This special issue comprises a series of papers written by former PhD students, as well as friends and colleagues, to celebrate the career of Alayne Street-Perrott, who is currently Professor of Physical Geography at Swansea University. Alayne's research career has been exceptional, marked by novel, cutting-edge research of the very highest quality in several disciplines, which addresses ‘big’ questions in Quaternary Science. She has promoted the importance of tropical environments through international cooperation and leadership, and developed fundamental concepts. She has made an immense contribution to our understanding of global change in the Quaternary, raising the discipline to new levels of scientific rigour.
