Department seminar on THURSDAY 22.1. at 12.15

Hi all,

The departmental seminar this week will be held on THURSDAY at 12.15. The seminar is given by Dr. Stephan Harrison from the College of Life and Environmental Sciences, University of Exeter, UK.

Dr. Harrison‘s main research interests lie in geomorphological responses to climate change. He has worked for twelve field seasons on the glaciers of Patagonia studying their fluctuation histories over the last 15,000 years and the geomorphological impact of recent glacier retreat on valley-side slopes.

Time: 12.15

Location: D112 Physicum, Kumpula Campus


All are welcome

Time: 14.15

Location: D112 Physicum, Kumpula Campus (NB: new lecture hall)



New Biogeography Model: Founder-event speciation, where a rare jump dispersal event founds a new genetically isolated lineage, has long been considered crucial by many historical biogeographers, but its importance is disputed within the vicariance school. Probabilistic modeling of geographic range evolution creates the potential to test different biogeographical models against data using standard statistical model choice procedures, as long as multiple models are available. I re-implement the Dispersal-Extinction-Cladogenesis (DEC) model of LAGRANGE in the R package BioGeoBEARS, and modify it to create a new model, DEC+J, which adds founder-event speciation, the importance of which is governed by a new free parameter, j. Both models are shown to be special cases of the “claSSE” model.

Further applications: Probabilistic modeling in biogeography opens up many possible research applications, including biogeographical stochastic mapping, biogeographical dating, and inclusion of phylogenetic information in species distribution modeling (SDM).

Departmental seminar this week – Tang Hui

Dear all,

This Friday (5.12) the departmental seminar is given by Dr. Tang Hui from the Division of Geology. This will also be Hui’s farewell talk as he was appointed as a postdoc researcher to Oslo University and will move to Norway in the beginning of next year.


Tang Hui: MOUNTAIN UPLIFT AND THE ASIAN MONSOON: A NEW MODELING PERSPECTIVE – The uplift and growth of the Tibetan Plateau and the surrounding mountains have long been recognized as an important player for the Asian monsoon evolution in the geological periods. But how the Asian monsoon responds to these tectonic changes remains controversial. In the seminar, I will introduce some recent climate modeling studies on the effects of different regional mountains on the Asian monsoon system, and discuss how these modeled effects could be applied to the geological periods.

Place: University of Helsinki, Department of Archaeology, Unioninkatu 38F, room F115.


Kaksi vierailuluentoa stabiili-isotooppitutkimuksesta arkeologiassa ma 26.5 klo 14 Helsingin yliopiston arkeologian oppiaineessa


Ensi maanantaina HY:n arkeologian oppiaineessa vierailee kaksi tutkijaa Durhamin yliopistosta Isosta-Britanniasta, jotka pitävät lyhyet luennot ajankohtaisista tutkimusaiheistaan. Molempien aiheet liittyvät stabiilien isotooppien hyödyntämiseen arkeologisten ihmisluuaineistojen tutkitmuksessa ja niiden pohjalta tehtyihin päätelmiin menneiden ihmisyhteisöjen ruokavaliosta.

Dr Janet Montgomery (Reader, Dept. of Archaeology): “Constructing chemical biographies: An investigation of diet across 5000 years from the Early Neolithic to the Great Famine (AD 1845-52)”
Montgomery on erikoistunut isotooppimenetelmiin ja on yksi tutkimusalan pioneereistä arkeologiassa, ks. tarkemmin

Maria Lahtinen (PhD student, Dept. of Archaeology): “Diet in Iin Hamina with stable isotope analysis”
