  abstract = {{D}espite a growing need for knowledge on how terrestrial ecosystems function, phenological studies are rather rare. {T}his study characterizes the temporal evolution of forest covers in {F}rench {G}uiana using variations in the {M}oderate {R}esolution {I}maging {S}pectroradiometer ({MODIS}) satellite signal and vegetation indices, such as the {S}hortwave {I}nfrared {W}ater {S}tress {I}ndex and the {E}nhanced {V}egetation {I}ndex. {T}he principle consists of reconstructing a temporal cycle mosaiced from a 9-year database. {R}ather than extract the phenological information from each pixel, dynamics were extracted from homogeneous groups of forest pixels enabling the identification of different phenological phases in forest ecosystems. {A} north-south gradient of chlorophyll activity emerged. {T}he further we moved to the south, the more forest groups consist of fast-growing and drought-tolerant species, whereas a north-south shift appeared at the start dates of phenological cycles. {T}his is a promising approach that paves the way for a much deeper understanding of the mechanisms governing the rainforest in {F}rench {G}uiana, as well as the responses of the {A}mazon forest to climate change and drought in the long term.},
