Excited to share our new research from my PhD thesis looking at how co-occurring environmental changes are related to Alaskan stream fishes with @C_MantykaP @Sharmalab https://onlinelibrary.wiley.com/doi/abs/10.1111/fwb.13569 (Thread 1/6)
We found that northern stream fish diversity and abundance may be benefitting from warming, while results were more varied for individual species. In particular, northern-adapted species appeared the most vulnerable to ongoing climatic changes. (2/6) Credits: L. Tran & T. Loewen
Our large study area allowed us to look at interesting seasonal trade-offs and interactions depending on local conditions. E.g. juvenile salmon increased with warmer spring and fall temperatures, but declined in regions experiencing both warmer and drier summer conditions (3/6)
So… what could this all mean for northern freshwater and anadromous fisheries? (4/6)
While northern fishing opportunities may increase overall, we caution that individual fisheries might suffer due to changing local conditions. Pro-active climate mitigation strategies will be increasingly important to protect northern fishes and the people that rely on them (5/6)
Finally, we used an amazing database created by the Alaska Department of Fish and Game. This is a publicly available resource containing thousands of northern fish collection records and has so much potential for future research questions. http://www.adfg.alaska.gov/index.cfm?adfg=ffinventory.main (6/6)
