  abstract = {{I}soprenoid and branched glycerol dialkanol diethers (iso {GDD}s and br {GDD}s) have recently been detected in various environments, including sediment, soil and peat deposits. {T}heir structures strongly resemble those of glycerol dialkyl glycerol tetraethers ({GDGT}s). {N}evertheless, the origin of {GDD}s and their link to {GDGT}s remain unclear. {H}ere we examined the concentration and distribution of iso {GDD}s and br {GDD}s, together with those of iso {GDGT}s and br {GDGT}s along a 4 m peat core from {T}anzania. {W}hereas br {GDD}s have only been detected to date in their core lipid ({CL}) form, we report here, for the first time, br {GDD}s in both {CL} and intact polar lipid ({IPL}) forms, suggesting a biosynthetic origin for br {GDD}s. {C}oncentrations of br {GDGT}s and br {GDD}s on one hand and of iso {GDGT}s and iso {GDD}s on the other hand, were observed to significantly co-vary ({R}-2 0.49-0.58; p < 0.05), both for the {CL} and {IPL} fractions. {M}oreover, the fractional abundance of each {GDD} correlated significantly with that of its {GDGT} analogue ({R}-2 0.33-0.97; p < 0.05). {T}aken together, the data show that {GDD}s and {GDGT}s are closely related and likely take part in common metabolic pathways, although the hypothesis of {GDD}s being degradation products of {GDGT}s cannot be excluded.},
