TL;DR: In this article, a robust framework for the application of compound-specific hydrogen isotopes in tropical Africa is presented, where the authors show that the δD values of the aquatic lipid biomarker n-C17 alkane were not correlated with the ǫd values of lake water, and that the combination of carbon and hydrogen isotope does help to differentiate between the metabolic pathway and growth form of organisms and therefore, the source of hydrogen used during lipid biosynthesis.

TL;DR: In this article, a set of non-linear binary mixing models using δ13C values from both C3 and C4 vegetation as end-members were used to estimate the fractional contribution (areal-based) of C3 vegetation cover represented by these sedimentary archives.

TL;DR: In this article, the carbon isotope composition (δ13C) of n-alkanes in common plants along a latitudinal gradient in C3/C4 vegetation and relative humidity in Cameroon and demonstrated that pentacyclic triterpene methyl ethers (PTMEs) and n-C29 and N-C31 in the same soil, derived mainly from C4 graminoids (e.g. grass) and C3 plants, respectively, were an effective proxy for reconstructing precipitation δD values even if plant types changed significantly.

TL;DR: Modern soil and litter samples from southeastern Cameroon, collected along a continuous forest-savanna transect, were analysed for pollen content to define modern pollen-vegetation relationships and defined inside the forest ecosystem more successional vegetation communities than the botanical surveys allowed.

TL;DR: This paper provided a detailed chronology of past vegetation changes in the tropical mountains of west-central Africa since the Last Glacial Maximum and discussed montane forest responses to climate change in terms of distribution and biodiversity.
