Whilst conducting her PhD research Hayley Keen helped produced two of short films about her research project Past environmental change on the eastern Andean flank, Ecuador:

  1. on her field work, which was the winning entry into the American Geophysical Union (AGU) student video competition in 2014, and
  2. a presentation summing up her PhD project in just 3 minutes!

First prize in the AGU student video competition (2014)

Three minute thesis (The Open University, 2014)

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.

Predicting the future by understanding the past: Climate change

As part of the 500,000 years of solar irradiance, climate and vegetation changes” Natural Environments Research Council funded (NE/K005294/1) project we have produced a wall chart explaining the type of research we do and how it can help to place on-going, and projected, climate change in context. The wall chart is designed for use in schools and universities. To obtain a copy of this, and other wall charts, please contact the British Ecological Society (direct wall chart link here).
