Small Water Bodies in Great Britain and Ireland: Ecosystem function, human-generated degradation, and options for restorative action

© 2018 Small, 1st and 2nd-order, headwater streams and ponds play essential roles in providing natural flood control, trapping sediments and contaminants, retaining nutrients, and maintaining biological diversity, which extend into downstream reaches, lakes and estuaries. However, the large geographic extent and high connectivity of these small water bodies with the surrounding terrestrial ecosystem makes them particularly vulnerable to growing land-use pressures and environmental change. The greatest pressure on the physical processes in these waters has been their extension and modification for agricultural and forestry drainage, resulting in highly modified discharge and temperature regimes that have implications for flood and drought control further downstream. The extensive length of the small stream network exposes rivers to a wide range of inputs, including nutrients, pesticides, heavy metals, sediment and emerging contaminants. Small water bodies have also been affected by invasions of non-native species, which along with the physical and chemical pressures, have affected most groups of organisms with consequent implications for the wider biodiversity within the catchment. Reducing the impacts and restoring the natural ecosystem function of these water bodies requires a three-tiered approach based on: restoration of channel hydromorphological dynamics; restoration and management of the riparian zone; and management of activities in the wider catchment that have both point-source and diffuse impacts. Such activities are expensive and so emphasis must be placed on integrated programmes that provide multiple benefits. Practical options need to be promoted through legislative regulation, financial incentives, markets for resource services and voluntary codes and actions

Transmission of integrated human herpesvirus 6 through stem cell transplantation: implications for laboratory diagnosis

We identified a stem cell donor with chromosomally integrated human herpesvirus (HHV)–6 and monitored the recipient for HHV-6 after transplantation. The appearance and subsequent increase in HHV-6 load paralleled engraftment and an increase in white blood cell count. Fluorescent in situ hybridization analysis showed integrated HHV-6 on chromosome band 17p13.3 in the donor and in the recipient after transplantation but not in the recipient before transplantation. The increase in viral load due to the genetic transmission of integrated HHV-6 could have been misinterpreted as substantial active infection and, thus, led to the administration of toxic antiviral therapy. We suggest that the confounding influence of integration be considered in laboratory investigations associating HHV-6 with disease

The Museum of Renaissance Music: A History in 100 Exhibits

This book collates 100 exhibits with accompanying essays as an imaginary museum dedicated to the musical cultures of Renaissance Europe, at home and in its global horizons. It is a history through artefacts—materials, tools, instruments, art objects, images, texts, and spaces—and their witness to the priorities and activities of people in the past as they addressed their world through music. The result is a history by collage, revealing overlapping musical practices and meanings—not only those of the elite, but reflecting the everyday cacophony of a diverse culture and its musics. Through the lens of its exhibits, this museum surveys music’s central role in culture and lived experience in fifteenth- and sixteenth-century Europe, offering interest and insights well beyond the strictly musicological field
