Images of modern pollen from Ghana

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…

The second day of our fieldwork saw us; transfer from Accra to Fumesua where FORIG is located (approximately 20 km south of Kumasi); meet up with FORIGs deputy director Dr Stephen Adu-Bredu to discuss fieldwork and outreach plans; and settle in to FORIG for the next two weeks.

The next two days will involve building pollen traps ready for deployment next and finalising the detailed day-to-day plan of work.

The latest round of fieldwork in Ghana is underway. Adele and myself are travelling out to collect pollen traps deployed last year as part of Adeles PhD research. We will be revisiting the sites in Ankasa, Bobiri and Kogyae that Adele and Phil visited last year. This time we are also accompanied by Lottie who will be delivering workshops on outreach activity engagement and the palaeoecology represented in the sediment record of Lake Bosumtwi.

Flying into land at Accra in the twilight we passed over a storm cell, with some fantastic convective clouds illuminated by flashes of lightning within. Once out of the airport, we were taken through the hustle and bustle of Accra streets, alive with evening activity. Finally reaching our destination for the night, the FORIG guesthouse. All three members of our party readily made for bed to get a good nights sleep before tomorrows journey to Kumasi.

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).

Summary (Adele): Sometimes, the old ones are the best, and this behemoth of a paper contains a huge amount of useful information on the chemical structure and development of Rye pollen grains. As I am working on the chemistry of grass pollen at the moment, it is incredibly useful to know that this sort of information exists and can be used to inform both my experimental protocol and interpretations.
