Impact of future climate change on water temperature and thermal habitat for keystone fishes in the Lower Saint John River, Canada (2018)
Journal Article
Dugdale, S. J., Curry, R. A., St-Hilaire, A., & Andrews, S. N. (2018). Impact of future climate change on water temperature and thermal habitat for keystone fishes in the Lower Saint John River, Canada. Water Resources Management, doi:10.1007/s11269-018-2057-7. ISSN 0920-4741

Water temperature is a key determinant of biological processes in rivers. Temperature in northern latitude rivers is expected to increase under climate change, with potentially adverse consequences for cold water-adapted species. In Canada, little is... Read More

Avian sensor packages for meteorological measurements (2018)
Journal Article
Thomas, R. M., MacKenzie, A. R., Reynolds, S. J., Sadler, J. P., Cropley, F., Bell, S., …Cai, X. (2018). Avian sensor packages for meteorological measurements. Bulletin of the American Meteorological Society, 99(3), 499-511. doi:10.1175/bams-d-16-0181.1

The increasing miniaturization of accurate, reliable meteorological sensors and logging systems allows the deployment of sensor packages on lightweight airborne platforms. Here, we demonstrate the safe and humane use of avian species (white-tailed an... Read More

Effect of discharge and habitat type on the occurrence and severity of Didymosphenia geminata mats in the Restigouche River, eastern Canada (2018)
Journal Article
Gillis, C., Dugdale, S. J., & Bergeron, N. E. (2018). Effect of discharge and habitat type on the occurrence and severity of Didymosphenia geminata mats in the Restigouche River, eastern Canada. Ecohydrology, 11(5), doi:10.1002/eco.1959

Since 2006, the Restigouche River watershed, eastern Canada, has been affected by nuisance growths of the mat‐forming diatom, Didymosphenia geminata. In 2010, in view of the potential impacts of this alga on the local Atlantic salmon fishery, we crea... Read More

Improving representation of riparian vegetation shading in a regional stream temperature model using LiDAR data (2017)
Journal Article
Loicq, P., Moatar, F., Jullian, Y., Dugdale, S. J., & Hannah, D. M. (2018). Improving representation of riparian vegetation shading in a regional stream temperature model using LiDAR data. Science of the Total Environment, 624, 480-490. doi:10.1016/j.scitotenv.2017.12.129

Modelling river temperature at the catchment scale is needed to understand how aquatic communities may adapt to current and projected climate change. In small and medium rivers, riparian vegetation can greatly reduce maximum water temperature by prov... Read More

Stream temperature under contrasting riparian forest cover: Understanding thermal dynamics and heat exchange processes (2017)
Journal Article
Dugdale, S. J., Malcolm, I. A., Kantola, K., & Hannah, D. M. (2018). Stream temperature under contrasting riparian forest cover: Understanding thermal dynamics and heat exchange processes. Science of the Total Environment, 610-611, 1375-1389. doi:10.1016/j.scitotenv.2017.08.198

Climate change is likely to increase summer temperatures in many river environments, raising concerns that this will reduce their thermal suitability for a range of freshwater fish species. As a result, river managers have pursued riparian tree plant... Read More

Controls on Arctic glacier-fed river water temperature (2016)
Journal Article
Mellor, C. J., Dugdale, S. J., Garner, G., Milner, A. M., & Hannah, D. M. (2017). Controls on Arctic glacier-fed river water temperature. Hydrological Sciences Journal, 62(4), 499-514. doi:10.1080/02626667.2016.1261295

The impact of climate change on Arctic rivers is expected to be severe. There is therefore a need for greater understanding of Arctic river temperature processes. This study quantifies the spatio-temporal variability of water temperatures in the Kårs... Read More

A practitioner's guide to thermal infrared remote sensing of rivers and streams: recent advances, precautions and considerations (2016)
Journal Article
Dugdale, S. J. (2016). A practitioner's guide to thermal infrared remote sensing of rivers and streams: recent advances, precautions and considerations. Wiley Interdisciplinary Reviews: Water, 3(2), 251-268. doi:10.1002/wat2.1135

Stream temperature is a key habitat variable controlling all physical and biological river processes. In light of the threat of climate change to fluvial environments, growing importance is being placed on the need to gain a better understanding of s... Read More

Aerial photosieving of exposed gravel bars for the rapid calibration of airborne grain size maps (2010)
Journal Article
