“…For instance, records of Chla in Lake Tanganyika (Bergamino et al., ; Horion et al., ) have shown variations at seasonal and inter‐annual scales, related to variations of the mixed layer depending on meteorological and climatic conditions, which determine water column processes in African Great Lakes (Nicholson, ; O'Reilly, Alin, Plisnier, Cohen, & McKee, ; MacIntyre, ; Tierney et al., ; Tierney, Smerdon, Anchukaitis, & Seager, ). However, the lack of continuity in records (Plisnier, Nshombo, Mgana, & Ntakimazi, ) hampers straightforward interpretation of changes involved and, too often, methodological differences between past and recent surveys further complicate data processing and interpretation. Therefore, studies on tropical lakes have mostly relied on paleolimnological approaches based on various sediment archives, such as fossil diatoms (Haberyan & Hecky, ) or phytoplankton pigments (Saulnier‐Talbot et al., ), with a time resolution of decades to centuries.…”
