Recent findings of monsoonal activity in Asia as old as 45 million years raises the fascinating possibility that these Monsoons may have triggered a global shift from the warm ice-free Greenhouse world, to the bi-polar Icehouse conditions the Earth still experiences today. Increased erosion and weathering of the uplifted Tibetan Plateau and Himalayas is currently advocated as the primary trigger for the enigmatic pCO2 drawdown that led to global cooling and rapid growth of the Antarctic ice sheet.
I am Natasha Barbolini, a new postdoctoral researcher in the Department of Ecosystem & Landscape Dynamics. Hosted by Dr Carina Hoorn, I joined the University of Amsterdam working on the MAGIC research project: (Monsoons of Asia caused Greenhouse to Icehouse Cooling). This ERC-funded project is headed by Dr Guillaume Dupont-Nivet at the University of Potsdam, Germany.

If you have exciting new research on past ecological change please consider submitting it to Vegetation History & Archaeobotany.
Two articles recently published on-line in the journal Vegetation History & Archaebotany (of which I am an Associate Editor) recently caught my attention.These explore:

The images taken by Adele Julier to help her with pollen identifications during her PhD at The Open University (UK) are now available to download. Please note these images are not of reference material but identifications, made by Adele and myself, of the pollen grains found within her pollen traps. The pollen traps were deployed within vegetation study plots in wet evergreen forest, semi-deciduous moist forest, and the forest-savanna transition zone in Ghana. Further publications on this work and a thesis coming soon…

I discovered what I think is the first colour pollen diagram this week. Published in 1948 and still looks beautiful.

Jippe Kreuning
University of Amsterdam MSc Biological Sciences student Jippe Kreuning investigated the contents of cesspits in the Dutch city of Deventer for his research project. Jippe investigated fossil pollen, seeds and other biological remains to discover what people in the ancient city were eating. In doing so Jippe gained new insights into ancient trade routes.

I am delighted to report that I have recently been appointed as an Associate Editor for the journal Vegetation History & Archaeobotany (VHA). The journals scope is global and covers Quaternary environmental and climatic change, with a specific focus on the Holocene and pre-historic human impacts on landscapes; often linking palaeoecological and archaeological research. My remit with VHA is to provide expertise on tropical, and in particular South American, studies. Recent articles in VHA with a South American focus include:
I hope that over the next few years we can publish some more exciting articles on the tropics in VHA and I would therefore like to encourage you to submit interesting high quality original research, reviews, or short articles for our consideration.
