Tula virus (TULV) is a vole-associated hantavirus with low or no pathogenicity to humans. In the present study, 686 common voles (Microtus arvalis), 249 field voles (Microtus agrestis) and 30 water voles (Arvicola spec.) were collected at 79 sites in Germany, Luxembourg and France and screened by RT-PCR and TULV-IgG ELISA. TULV-specific RNA and/or antibodies were detected at 43 of the sites, demonstrating a geographically widespread distribution of the virus in the studied area. The TULV prevalence in common voles (16.7 %) was higher than that in field voles (9.2 %) and water voles (10.0 %). Time series data at ten trapping sites showed evidence of a lasting presence of TULV RNA within common vole populations for up to 34 months, although usually at low prevalence. Phylogenetic analysis demonstrated a strong genetic structuring of TULV sequences according to geography and independent of the rodent species, confirming the common vole as the preferential host, with spillover infections to co-occurring field and water voles. TULV phylogenetic clades showed a general association with evolutionary lineages in the common vole as assessed by mitochondrial DNA sequences on a large geographical scale, but with local-scale discrepancies in the contact areas.

Understanding the relationship between dietary fat and physiological responses is crucial in species adapted to arid environments where water scarcity is common. In this study, we present a comprehensive exploration of gene expression across five tissues (kidney, liver, lung, gastrointestinal tract and hypothalamus) and 17 phenotypic measurements, investigating the effects of dietary fat in the desert-adapted cactus mouse (Peromyscus eremicus). We show impacts on immune function, circadian gene regulation and mitochondrial function for mice fed a lower-fat diet compared with mice fed a higher-fat diet.

This article explores framings of life, death, health, and invasion on an English chalk stream. It focuses on the ways in which these notions have been put to work in recent history, in relation to each other, and in relation to particular species and spaces. By 2019, narratives of a chalk stream in South-East England as a dead river expanded beyond retort to intermittent waterlessness.

Body size of organisms is a key trait influencing nearly all aspects of their life history. Despite growing evidence of Bergmann's rule, there is considerably less known about the links between body size and the maximum capacity to thermoregulate of an animal in response to extreme cold or hot environment. Thermal characteristics such as resting metabolic rate (RMR) and non-shivering thermogenesis (NST), and the upper- and lower-critical temperatures of the thermal neutral zone (TNZ) were investigated in small and large body sized striped hamsters (Cricetulus barabensis).

The production of biopharmaceuticals is a chemical- and water-intensive process. The consumption of water and chemicals is partly due to the need for many different buffers in large volumes during the downstream process, typically consisting of several chromatography steps. Given the global commitment to the goals for sustainable development and the anticipated growth of the biopharmaceutical market, the consumption of large buffer volumes is expected to become problematic.
