Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

Journal of Anatomy, EarlyView.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Evolutionary history of Middle American Rhamdia (Siluriformes: Heptapteridae) inferred from comparative mitogenomic data: Insights on historical biogeography and cave colonization in the group

Journal of Systematics and Evolution, EarlyView.
This study investigated the systematics and biogeography of the Middle American clade of Neotropical catfishes of the genus Rhamdia using mitogenome‐wide comparative data. Results refine and corroborate previous phylogenetic hypotheses, including the deep paraphyly of the species Rhamdia laticauda; they support a scenario of northward dispersal from ...

Expelled by the Antarctic ice: Evolutionary history of the tribe Cunonieae (Cunoniaceae)

Journal of Systematics and Evolution, EarlyView.
Multiple fossil calibration points reveal recent radiations and biogeographical history of the Cunonieae tribe. The most densely sampled phylogeny allowed to infer Antarctica and Patagonia as areas of origin, confirming the reestablishment of Pterophylla and revealing the northward movement of Weinmannia into the tropical Andes. Conflicting plastid and

Do culturable seed endophyte communities differ between native and invasive Fabaceae sharing the same habitat?

Plant Biology, EarlyView.
Invasive Acacia seeds harbour richer and more functionally diverse endophyte communities than co‐occurring native Fabaceae, which could enhance establishment and invasion success of Acacia. Abstract Invasive plant species threaten ecosystems by decreasing biodiversity and altering their functioning.
