Job: PhD in Macroecology/Palaeoecology

September 12, 2018
WDG

There is a vacancy for a 3 or 4-year PhD position at the University of Bergen’s Department of Biological Sciences.

The successful candidate will be primarily responsible for developing tests for evaluating the effect of humans through space and time on species range sizes and developing analyses to compare diversity patterns and range sizes from different data sources in mountainous regions, interpretation of pollen-stratigraphical data for reconstructing range size through time, and applying mapping techniques to assess the patterns over time and space. 

Special requirements for the position:

  • The successful candidate must have knowledge and experience of quantitative analyses of ecological or palaeoecological data (preferably using the statistical software R), as well as documented skills in one or more research fields relevant to the position.
  • Experience with large databases and some experience with geospatial analysis software, such as in ESRI ArcGIS, QGIS or R is an advantage.
  • It would be beneficial to have a background in one or more of the following research fields: biogeography, macroecology, palaeoecology, mountain biodiversity, community ecology, applied statistics, numerical ecology.

Main PhD Supervisor:  Prof. John-Arvid Grytnes. Co-supervised by: Dr. Suzette Flantua

Amazonian coring isn’t boring

By Seringe Huisman (MSc Biological Sciences, Institute for Biodiversity & Ecosystem Dynamics, University of Amsterdam)

Hello all! You might have been wondering if I died in the middle of Amazonian nowhere, since I haven’t come back to writing a blog after we left for fieldwork in July. Given we were in an Amazonian region full of venomous snakes that could have been the case, but the good news is I just didn’t get around writing it because I got carried away by the findings of my project! We actually had a very successful field trip – apart from some minor issues like the lake swallowing equipment, sinking waist-high into the mud each step of our 7 hour long ‘trail’ to the lakes, and almost not getting my precious samples through airport security.

Introducing Milan Teunissen van Manen

WDG

Milan Teunissen van ManenMy name is Milan Teunissen van Manen and I just finished my first week as a Ph.D. researcher with the Palaeoecology & Landscape Ecology (P&L) group in the Institute for Biodiversity & Ecosystem Dynamics (IBED) at the University of Amsterdam (UvA)!

My undergraduate studies were interdisciplinary in nature: I did a BSc Beta-Gamma (Institute for Interdisciplinary Studies (IIS), UvA) where students are taught to collaborate between different disciplines. Ecology has always been an interest of mine, so I was quick to specialize in that field. In my final year of my bachelor I came in contact with paleoecology and did not hesitate to make sure my first master’s project (MSc Biological Science, IBED, UvA) would be with the P&L research group (IBED) – a worked on a project on tropical rainforest dynamics in Miocene Amazonia. After that I got the chance to test my skills outside research institutes: during the Tesla consultancy Minor (IIS) I got firsthand practical experience in developing urban green areas from start to finish for the municipality of Amsterdam. The focus of that project was to increase the ecologic, educational, scientific, and social value of the natural areas on Amsterdam Science Park. It was great to see my scientific background put to good use outside the research community. The project is still active today.

After a short period of working in education and sustainability consultancy I seized the opportunity to, once more, join the P&L research group – this time as a Ph.D. student under the watchful eyes of William Gosling and Boris Jansen. My project revolves around characterizing biomarker and modern pollen-rain signals across the altitude of the Ecuadorian Andes vegetation. A great opportunity at the frontier of tropical research!

If the first week is any indication, I foresee to a lot of collaboration, hard work, exploration and adventure in the coming years!

Pollen database of Early-Miocene Amazonian palynological diversity

MSc Biological Sciences, University of Amsterdam.

As part of my MSc research project on Early-Miocene paleodiversity shifts due to marine incursions in the Amazon basin, I recorded and photographed large numbers of palynomorphs. The database consists of a set of images (Teunissen van Manen, 2015a) that I took with my smartphone (bundled in pdfs for sharing purposes) and an Excel overview file (Teunissen van Manen, 2015b) where each of the entries is described. Some of the entries are well documented taxa (C’mon, who hasn’t heard of Zonocostites ramonae and Mauritidites franciscoi before?) while others are “types” that are not formally described – mainly because in Amazonian sediments new, unseen palynomorphs pop up all the time. Indeed, this was the reason why I started the database in the first place: I was merely trying to keep up with the vast diversity that I encountered during sample counting.

Seeing the added value of having a digital record of the palynological diversity from the Amazon basin samples, my project supervisor, Carina Hoorn (UvA), encouraged me to publish the database online so others could also access it. I’d like to invite you to take a look. I hope it can maybe help you with identifying taxa or, who knows, linking taxa across the Amazon basin… if you do, please let me know!

…or maybe it will have you rejoice in the huge diversity and alien beauty of pollen morphology, just as it rejoiced me as I was working through my (seemingly endless) samples.
