A team of researchers from the West Virginia University (WVU) Davis College of Agriculture, Natural Resources and Design recently published a journal article that provides an assessment of thermal characteristics and climate change vulnerability for brook trout habitats in the upper Shavers Fork sub-watershed in West Virginia.
The article, Can brook trout survive climate change in large rivers? If it rains, appears in volumes 207 and 208 of Science of the Total Environment and was published by Dr. Eric Merriam, Postdoctoral Researcher with the Division of Forestry and Natural Resources; Dr. Rodrigo Fernandez, Postdoctoral Researcher with the Division of Forestry and Natural Resources; Dr. Todd Petty, Professor of Aquatic Sciences in the Wildlife and Fisheries Resources program and Associate Dean of Academic Affairs in the College; and Dr. Nicolas Zegre, Associate Professor of Forest Resources Management.
“Most studies have focused on how increasing air temperatures will translate into a loss of thermally suitable brook trout habitat, without considering how changes in precipitation and streamflow might alter habitat vulnerability to climate change,” said Merriam.
“Climate models are projecting substantially higher stream flow levels in this region and also substantially higher temperatures,” Petty added.
“Our results suggest that, within this and similar systems, projected increases in precipitation and streamflow will largely offset the effects of increasing air temperatures” said Merriam.
“This combination results in some hope for cold water species. But it also raises the specter of more flooding and raises the question, “what if it doesn't rain?,” concluded Petty.
