Establishing an Ecuadorian Isoscape: The Importance of Baseline Strontium Data in a Volcanic Landscape Estableciendo un Iso‐Paisaje Ecuatoriano: La Importancia de los Datos de Referencia de Estroncio en un Paisaje Volcánico

American Journal of Biological Anthropology, Volume 187, Issue 2, June 2025.
ABSTRACT Objectives Strontium isotopes (87Sr/86Sr) have been used worldwide to track migrations and identify nonlocal individuals in the past. In South America, these studies often use comparative baseline maps, or isoscapes, established by samples from archaeological fauna and geologic formations. However, baseline research has focused on coastal Peru

N‐terminal pro B‐type natriuretic peptide as biomarker to predict pre‐eclampsia and maternal–fetal complications

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 4, Page 447-455, April 2025.
ABSTRACT Objective A soluble fms‐like tyrosine kinase‐1 (sFlt‐1)‐to‐placental growth factor (PlGF) ratio cut‐off of 38 is currently considered optimal for ruling out pre‐eclampsia (PE); however, implementation of this ratio in clinical practice is limited.

Vulnerability of Southern Hemisphere bats to white‐nose syndrome based on global analysis of fungal host specificity and cave temperatures

Conservation Biology, Volume 39, Issue 2, April 2025.
Abstract White‐nose syndrome (WNS), a disease affecting hibernating bats, is caused by the fungal pathogen Pseudogymnoascus destructans (Pd). Since the initial introduction of Pd from Eurasia to the United States in 2006, WNS has killed millions of bats throughout the temperate parts of North America.

COSST: A tool to facilitate seed provenancing for climate‐smart ecosystem restoration

Journal of Applied Ecology, Volume 62, Issue 3, Page 677-688, March 2025.
Our tool can guide where to source seeds for species lacking range‐wide information on genetic structure, which is the case for a substantial proportion of the tropical flora, where ecosystem restoration is of paramount importance. Abstract Selecting the best seed sources is a key step in ecological restoration planning especially under climate change.
