Taxonomy, phylogeny and biogeography of cisticolas (Cisticola spp.)
Published 2015“…Most of the mean divergence date estimates correlated with periods of climate variability and episodes during which there is evidence for high lake levels in Africa, rather than correlating with Plio-Pleistocene glaciation, offering evidence that open habitats may have become fragmented during extremes of both arid and humid climates.…”

Characterising the response of the mixed and the transitional layers to the passage of storms in the Sub-Antarctic Zone
Published 2020“…The mixed-layer depth (MLD) is used widely as proxy for vertical extent of upper-ocean mixing, with the assumption that it integrates the variability of atmospheric forcing. Recent studies have shown that this shear-driven mixing associated with storms can actually extend below the base of the MLD into the transitional layer (TL). …”
