This section includes the abstracts of some of the PhD-Dissertations submitted in Spain during the 2013–2014 academic year as well as some others not published in earlier volumes of Ardeola. They are in alphabetical order by University where they were presented and, then, by year and alphabetical order of the author's surname.

^* This issue includes exceptionally two theses of the year 2014–2015. We believe it is important to provide this information in this volume instead of postponing its publication to 2015.
