This page will provide links to the many talk series, seminars and invited lectures in the school of biology. A rolling list of upcoming events can be found at the bottom of this page.
The Institute of Behavioural and Neural Sciences is an interdisciplinary community of researchers who study the behaviour of human beings and other animals from cellular, neural, cognitive and evolutionary perspectives. The Institute brings together faculty members, research staff and students from the Schools of Biology, Psychology & Neuroscience, Medicine and Chemistry, with the aim of fostering progress at interfaces of the behavioural and neural sciences.
The Cognitive Journal Club is made of members of members of the Schools of Psychology and Neuroscience, and Biology. CJC meets fortnightly on Mondays over lunch during term times for an informal discussion of recent empirical and theoretical articles about cognition.
The Friday lab chat series is a get-together of evolutionary biologists who meet in the seminar room of the Sir Harold Mitchell Building, 1 pm on Fridays, for informal talks about research. Bring your lunch. And a willingness to participate.
The Laland lab meets biweekly to informally discuss both their work and recent papers. They meet on Thursdays at 10.30. Please contact Keelin Murray (kmm26(at)st-andrews.ac.uk) to find out more.
You can find details of seminars in the biomedical sciences research complex here.
BSRC conferences are listed here.
The SOI seminar series take place on Thursdays at 1pm in the Garry lecture theatre. You can find out more at the SOI web pages.
BioNet is a network aimed at making the School of Biology feel more connected. It is a good way to get out and meet like-minded people from your department who want to get out there, talk about what they do and have fun! They run bi-monthly seminar sessions, social events, field-trips and workshops.

A vocal repertoire subset from seven groups of pilot whales and 11 groups of killer whales recorded in the Vestfjord in northern Norway during the time period 2004 until 2011 will be presented.
Using observer-based acoustic analysis 129 call types and 25 subtypes for long-finned pilot whales, and 60 call types and 25 subtypes for killer whales were classified. Per group, pilot whales used an average of 36 call types and killer whales 25. The general structure of call types was similar, with most call types consisting of one segment and two elements with different structures. The main element structure in pilot whale and killer whale calls was an ascending frequency band. The amount of two-voiced calls was 29% for pilot whales and 47% for killer whales. In addition, there were different call type combinations and repetitions and ultrasonic whistles, already known in killer whales, but newly described for pilot whales in this study.
The main difference between vocal repertoires of the two species appeared at the call type sharing between the groups. Pilot whales only shared 28% of their call types and 37% of their total calls with at least one other group, whereas killer whales shared 59% of their call types and 90% of their total calls. In 2011 a new foraging method for salmon by killer whales in Norway was discovered and for the first time it was possible to observe the same two groups of killer whales for three and six months and describe a full repertoire with 59 call types and 25 subtypes. It was not possible to completely separate the calling of the two groups, but nevertheless it shows that the vocal repertoire is larger than earlier described. In addition, context-specific vocalisations were detected during salmon feeding and non-feeding contexts, and compared to herring feeding and a food association call from the Icelandic killer whale population. Specifically, certain call type combinations contained the same beginning part in all feeding contexts, but the combinations differed for salmon and herring feeding and between groups. These differences will be discussed in the light of possible referential and/or arousal calling in association with food in killer whales.
