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.
The fifth day of the AFQUA conference started with the second session on “Archaeological Landscapes”. Talks included: (i) a tribute to the work of Dick Grove in Quaternary work in Africa since the 1950’s, including possibly the earliest definition of the African humid period in his paper Grove & Warren (1968) (D.S.G. Thomas), and (ii) a highlight of new work on the Kisese II Rock Shelter in Tanzania (K. Ranhorn). Then to take us up to lunch Prof. David Nash treated us to a tour de force through the use of historical records in reconstructing past climates; including quotes from the fantastically named Holloway Helmore a missionary to Lekatlong in 1851 commenting on drough and how to turn this type of information into a regional/continental synthesis!
The afternoon session focused around the theme of “East Africa”. This session started with two talks on one of the “least known ancient civilization” in Ethiopia the Aksumite and pre-Aksumite peoples, and the resilience of these peoples to environmental and land-use change (V. Terwilliger and Z. Eshetiu). Other work presented on the morphometry of hominin skulls showing gradual development from 500,000 to 315,000 years ago which lead up to the appearance of anatomically modern humans (E. Mbua).
Mark Bush and I are proud to announce that a tribute to Prof. Daniel Livingston and Prof. Paul Colinvaux has recently been published in Quaternary Research. Dan and Paul were both pioneers of tropical pal(a)eoecology and both died in the spring of 2016 . To mark their passing Mark and I have guest edited ten new papers on palaeoecology drawn from researchers, and regions, of the tropics in which Dan and Paul worked (Bush & Gosling, 2018). We would like to thank Quaternary Research Senior Editor Derek Booth for giving us this opportunity and assisting greatly in the process of compiling the manuscripts. We would also like to thank all to contributing authors for their hard work and dedication to the project. We hope that you will enjoy reading the manuscripts and find them a fitting tribute to the life and work of these two great researchers.
