Abstract
This volume comprises the proceedings of the Joint Meeting of the XIV International Conference on Ephemeroptera and XVIII International Symposium on Plecoptera, held between the 31st May and 5th June 2015 in Aberdeen, Scotland. The International Conferences on Ephemeroptera and Symposia on Plecoptera are held every three years and allow specialists on these orders to interact and present their work. The 2015 Joint Meeting was the first to be held in the United Kingdom and was hosted at the James Hutton Institute. Seventy five delegates from 29 countries attended the meeting and presented 35 oral presentations and 29 posters. The meeting consisted of sessions on phylogeny, taxonomy and systematics; general ecology; behavioural ecology; distribution and biogeography; adaptation and change; biodiversity and conservation; and morphology. The fifteen papers in this volume are representative of the papers and posters presented at the meeting, and were accepted after peer review by international specialists.
