From the abstract: “This systematic review and meta-analysis estimated the pooled prevalence of wasting and acute malnutrition among paediatric cancer patients in Africa, evaluated the impact of diagnostic assessment methods on reported prevalence, and characterised associations with adverse clinical outcomes.”

Historical biogeography of the Papilio machaon species group.Summary of BEAST and RASP analyses, ancestral area reconstruction model S-DIVA. Region C (Indomalayan realm) is not shown as specimens originated there are included in the collapsed P. machaon clade. Pie charts on each node depict the relative probabilities of ancestral ranges. Numbers below nodes indicate Bayesian posterior probability (see S11 Fig for the expanded tree).

Tracing Old World Swallowtail evolution in the Palearctic

From the abstract: “Based on a dataset of 585 samples originating from across the Palearctic region and four genes (COI, CAD, Ca-ATPase, and 28S) for a subset of these samples, we studied the phylogenetic relationships within and between the Old World Swallowtail (Papilio machaon Linnaeus, 1758) and its closest relatives in the Palearctic region.”
