Monitoring Biodiversity: Lessons from a Trans-Andean Megaproject

Trans-Andean Ancistrus (Siluriformes: Loricariidae).

We review the trans-Andean species of Ancistrus from Panama, Colombia and Venezuela. Based on analyses of meristic, morphometric and pigmentation pattern data of preserved specimens, eight of sixteen species reported from this region are considered valid and two new species are described. Here we review Ancistrus chagresi Eigenmann & Eigenmann 1889 from both slopes of central Panama; A. centrol...

Contrasting plant diversification histories within the Andean biodiversity hotspot.

The Andes are the most species-rich global biodiversity hotspot. Most research and conservation attention in the Andes has focused on biomes such as rain forest, cloud forest, and páramo, where much plant species diversity is the hypothesized result of rapid speciation associated with the recent Andean orogeny. In contrast to these mesic biomes, we present evidence for a different, older divers...

Monitoring of Adrenal Functions Amid the COVID-19 Pandemic: Lessons From Pediatric Leukemia

Introduction: Glucocorticoids are considered the cornerstone of the induction phase in all treatment protocols of acute lymphoblastic leukemia (ALL). Among the adverse effects of high-dose glucocorticoid treatment, adrenal insufficiency is secondary to suppression of the hypothalamic-pituitary-adrenal (HPA) axis. This drawback of exogenous steroid therapy gains a contemporary particular relevan...
