BACKGROUND It is well known that nutrient availability can alter the gut microbiota composition, while the effect on diversity and temporal stability remains largely unknown. METHODS Here we address the equine caecal microbiota temporal stability, diversity, and functionality in response to diets with different levels of nutrient availability. Hay (low and slower nutrient availability) versus...
The diversity and composition of ecological communities often co-vary with ecosystem productivity. However, the relative importance of productivity, or resource abundance, versus the spatial distribution of resources in shaping those ecological patterns is not well understood, particularly for the bacterial communities that underlie most important ecosystem functions. Increasing ecosystem produ...
The emergence of third-generation, technology-based public bikeshare schemes offers new opportunities for researching cycling behaviour. In this study, data from one such scheme, the London Cycle Hire Scheme (LCHS), are analysed. Algorithms are developed for summarising and labelling cyclists’ usage behaviours and tailored visual analysis applications are designed for exploring their spatiotemp...
Introduction Conclusions References
salinity stress is one of the most important abiotic factors that restrict the growth and yield of many plants. salinity can increasingly influence the host susceptibility, occurrence and development of plant diseases due to its negative effects on the host plants. mycorrhizal fungi are able to increase the tolerance of some plants to salinity. in this study, the biological effects of glomus mo...
