Fecal Steroids as Tracers of Human Population and Waste Management Practices at the Ancient Maya City of Ucanal, Guatemala

open access: yesArchaeometry, EarlyView.
ABSTRACT Geochemical data compiled from dried sediments from three water reservoirs at the ancient Maya city of Ucanal, Petén, Guatemala, reveal low to undetectable fecal biomarker concentrations. These low concentrations may be the result of the aerobic decay of sterols combined with well‐managed waste disposal practices.

Limited drought tolerance in the neotropical seasonally dry forest plants impairs future species richness

open access: yesPlant Biology, EarlyView.
Global climate change will likely modify the plant assemblages of the Neotropical seasonally dry forest based on the physiological capabilities of the species. Abstract Neotropical seasonal dry forest (NSDF) is one of the most threatened ecosystems according to global climate change predictions.

A computational model for retinal haemodynamics under gravitational and postural variations

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The haemodynamic impact of gravitational and postural changes on the retina, and its relevance to spaceflight associated neuro‐ocular syndrome (SANS), remains incompletely characterized. This study assesses retinal haemodynamics from upright to head‐down tilt using a lumped‐parameter model that dynamically couples intraocular ...
