  abstract = {{T}he first meter of sediment in {L}agoa do {B}oqueirao [{R}io {G}rande do {N}orte {S}tate ({RN}), {B}razil] is characterized by low sedimentation rates over the period 1000 {BC}-1500 {AD} and a high sedimentation rate in the top 20 cm, corresponding to the last 10 years {S}everal pentacyclic triterpene methyl ethers ({PTME}s) such as taraxer-14-en-3 alpha-ol {ME} (crusgallin) and arbor-9(11)-en-3 beta-ol {ME} (cylindrin) occur in all the samples selected {T}he major change in sedimentation rate recorded at 20 cm is accompanied by a change in {PTME} concentration and distribution {S}ediments deposited during the period 1000 {BC}-1500 {AD} contain {PTME}s in low concentration (1 3 mu g/g sed), which could constitute a geochemical background of the grass that naturally developed in the catchment {H}igh {PTME} concentrations occur during the period 1996-2000. {T}hese result mainly from high concentrations of a compound tentatively assigned as arbor-8-en-3 beta ol {ME}, a potential diagenetic derivative of cylindrin {T}he increase corresponds to the beginning of intensive cultivation of {C}ynodon dactylon and {Z}oysia japonica (arundoin and cylindrin producers), for the production of turf to cover {B}razilian football stadiums and golf practices {T}he results constitute a novel application of {PTME}s to reconstruct land-use changes from lake sediment archives ({C}) 2009 {E}lsevier {L}td {A}ll rights reserved},
