Journal Article
Everall, N. C., Johnson, M. F., Wood, P., Farmer, A., Wilby, R. L., & Measham, N. (2017). Comparability of macroinvertebrate biomonitoring indices of river health derived from semi-quantitative and quantitative methodologies. Ecological Indicators, 78, 437-448. https://doi.org/10.1016/j.ecolind.2017.03.040

Aquatic macroinvertebrates have been the basis for one of the primary indicators and a cornerstone of lotic biomonitoring for over 40 years. Despite the widespread use of lotic invertebrates in statutory biomonitoring networks, scientific research an...

The importance of biotic entrainment for base flow fluvial sediment transport (2016)
Journal Article
Rice, S. P., Johnson, M. F., Mathers, K., Reeds, J., & Extence, C. (2016). The importance of biotic entrainment for base flow fluvial sediment transport. Journal of Geophysical Research: Earth Surface, 121(5), 890-906. https://doi.org/10.1002/2015JF003726

Sediment transport is regarded as an abiotic process driven by geophysical energy, but zoogeomorphological activity indicates that biological energy can also fuel sediment movements. It is therefore prudent to measure the contribution that biota make... Read More about The importance of biotic entrainment for base flow fluvial sediment transport.

Seeing the landscape for the trees: metrics to guide riparian shade management in river catchments (2015)
Journal Article
Johnson, M. F., & Wilby, R. L. (2015). Seeing the landscape for the trees: metrics to guide riparian shade management in river catchments. Water Resources Research, 51(5), https://doi.org/10.1002/2014WR016802

Rising water temperature (Tw) due to anthropogenic climate change may have serious consequences for river ecosystems. Conservation and/or expansion of riparian shade could counter warming and buy time for ecosystems to adapt. However, sensitivity of...

What else do managers need to know about warming rivers? A United Kingdom perspective: Managing warming rivers (2015)
Journal Article
Orr, H. G., Johnson, M. F., Wilby, R. L., Hatton-Ellis, T., & Broadmeadow, S. (2015). What else do managers need to know about warming rivers? A United Kingdom perspective: Managing warming rivers. Wiley Interdisciplinary Reviews: Water, 2(2), 55-64. https://doi.org/10.1002/wat2.1062

River flow and water temperature are fundamental controls of freshwater ecosystems. Hence, future warming could impact valued habitats and species, particularly those with cold water preferences (such as salmonids). Warming could also exacerbate exis...

1. Rising water temperatures under climate change are expected to affect the phenology of aquatic insects, including the mayfly Ephemera danica Müller which is widespread throughout Europe.

2. To assess temporal and spatial variability in mayfly e... Read More about Detecting phenology change in the mayfly Ephemera danica: responses to spatial and temporal water temperature variations.

Animal perception in gravel-bed rivers: scales of sensing and environmental controls on sensory information (2014)
Journal Article
Johnson, M. F., & Rice, S. P. (2014). Animal perception in gravel-bed rivers: scales of sensing and environmental controls on sensory information. Canadian Journal of Fisheries and Aquatic Sciences, 71(6), 945-957. https://doi.org/10.1139/cjfas-2013-0474

Animals make decisions based on the sensory information that they obtain from the environment and other organisms within that environment. In a river, this information is transported, transmitted, masked, and filtered by fluvial factors and processes...
