After more than a year of unrest, a small effusive eruption commenced in Fagradalsfjall, Iceland, on 19 March 2021. The eruption lasted six months. The first six weeks were characterized by multiple fissure openings, and the remainder was dominated by effusive activity from a single crater. During the eruption, lava and low-level gases propagated over the complex terrain: a hyaloclastite massif with mountain peaks up to about...
A comparison of airway pressures for inflation fixation of developing mouse lungs for stereological analysesNARA Subscribed
The morphometric analysis of lung structure using the principles of stereology has emerged as a powerful tool to describe the structural changes in lung architecture that accompany the development of lung disease that is experimentally modelled in adult mice. These stereological principles are now being applied to the study of the evolution of the lung architecture over the course of prenatal and postnatal lung development in...
Ecological divergence of two sympatric lineages of Buggy Creek virus, an arbovirus associated with birdsNARA Subscribed
Most arthropod‐borne viruses (arboviruses) show distinct serological subtypes or evolutionary lineages, with the evolution of different strains often assumed to reflect differences in ecological selection pressures. Buggy Creek virus (BCRV) is an unusual RNA virus (Togaviridae, Alphavirus ) that is associated primarily with a cimicid swallow bug ( Oeciacus vicarius ) as its vector and the Cliff Swallow ( Petrochelidon pyrrhono...
Host and vector movement affects genetic diversity and spatial structure of Buggy Creek virus (Togaviridae)NARA Subscribed
Determining the degree of genetic variability and spatial structure of arthropod‐borne viruses (arboviruses) may help in identifying where strains that potentially cause epidemics or epizootics occur. Genetic diversity in arboviruses is assumed to reflect relative mobility of their vertebrate hosts (and invertebrate vectors), with highly mobile hosts such as birds leading to genetic similarity of viruses over large areas. Ther...
