Computed tomography reveals multiple origins of extreme caudal vertebral pneumaticity in sauropod dinosaurs

open access: yesJournal of Anatomy, EarlyView.
Here, we present novel CT scan data of caudal vertebrae of six Middle–Late Jurassic sauropods, representing several eusauropod lineages. We synthesise these new data with a comprehensive critical appraisal of purported external and internal evidence for caudal vertebral PSP in Sauropodomorpha.

Bark‐associated yeasts and their potential role as tree carbon sink at the treeline of the southern Andes

open access: yesPlant Biology, EarlyView.
In the southern Andes, Nothofagus pumilio shows elevational decreases in the concentrations of carbon reserves which are the food of bark‐associated yeasts, suggesting that competition for carbohydrates between tree growth and bark‐associated yeasts may cause carbon shortages.

The biology of Mustelus schmitti in southern Patagonia, Argentina

open access: yesJournal of Fish Biology, 2000
The relationship of body weight and total length (LT) of Mustelus schmitti in southern Patagonia was different between sexes. Changes in maturity stages in males appear at larger sizes in Ría Deseado specimens than in the Mar del Plata area. Mature females ranged from 795 to 913 mm while all male specimens >759 mm LT were mature.
