The second in my series highlighting papers in the recent volume of Palaeoecology of Africa (published entirely open access online) focuses on the research articles. The research articles make up the ‘guts’ of the volume, comprising 10 of the 24 papers. Three of these are from western Africa (Dinies et al.; Gosling et al.; Lemonnier & Lézine), two from eastern Africa (Githumbi et al.; Kinyanjui et al.), two from central Africa (Richards; Gaillard et al.), and three from southern Africa (Chevalier et al.; Hill & Finch, Hill et al.). These research articles present new data and key insights into past environmental change in Africa, which fall into two broad categories, providing information on: (i) how we can extract information from pollen data sets, and (ii) the processes operating to drive vegetation.
We are looking for a researcher with a geosciences background to explore the physical properties of the sediments recovered from Lake Bosumtwi (Ghana). The Lake Bosumtwi sediments we recovered by the International Continental Scientific Drilling Program in 2004 and have been found to span the last c. 1.07 million years (Koerbel et al., 2005). This project will examine the borehole data and relate this ongoing palaeoenvironmental studies at the site (Miller & Gosling, 2014; Miller et al., 2016).
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.
