The lichen flora of the Chagos Archipelago : including a comparison with other island and coastal tropical floras [PDF]

open access: yes, 2000
The 1996 Chagos Expedition provided the first opportunity to study the archipelago’s lichen flora. Seventeen of the 55 islands were ecologically investigated, some in more detail than others, and lists and representative collections of lichens have been ...

Cellular mechanisms of radiation‐induced myocyte dysfunction: effects on calcium handling, ion channel regulation and mitochondrial energetics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Dose‐dependent effects of radiation on cardiac electrophysiology and arrhythmia susceptibility. At low radiation doses (left), increased reactive oxygen species (ROS) initiate an ROS–Ca2+ positive feedback loop involving calcium/calmodulin‐dependent protein kinase II (CaMKII) activation, enhanced L‐type Ca2+ current (ICaL ...

Beat‐to‐beat variability of ventricular repolarization reveals sex‐specific instability and proarrhythmic risk

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Politica e grandi scoperte geografiche

open access: yesLaboratoire italien, 2008
Tra Quattro e Cinquecento, Spagna e Portogallo procedettero all’esplorazione dell’ignoto fondandosi su quanto la scienza e la Chiesa insegnavano, ma – quando conveniva – non esitarono ad accogliere ipotesi e progetti che contrastavano con quanto si conosceva. La concorrenza fra questi due stati indusse a procedere sempre piu avanti in territori che per

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis
