Jamaica Bay’s Fish Ecosystem Reshaped by Climate Change
A study examining how fish in Jamaica Bay responded to environmental stressors over the past three decades found a fish ecosystem reshaped due to climate change.
A Significant Shift in Fish Populations
Although it has long been confirmed that changes in water temperature are displacing fish, this study is the first and largest to articulate the significant changes in the biologically rich wetland estuary in southeast Queens and Brooklyn. In it, researchers detailed the steady exodus of many established species from Jamaica Bay to colder waters up north and an increase in the number of newly arriving warm-water species.
Expert Analysis
Queens College Biology professor John Waldman, an expert on how humans impact fish populations, co-authored the study published in the Ecological Society of America journal Ecosphere over the summer. It is titled “Decoupled shifts of dominant and rarer fish species as a response to warming and extreme events in a large estuary.”
Data Collection and Analysis
Waldman and former QC biology professor José D. Anadón utilized a significantly large data set compiled by the New York State Department of Environmental Conservation. This set gave them insights into over 900,000 fish living in Jamaica Bay from 1989 to 2017 and allowed them to reach detailed conclusions.
Conclusions
They discovered that while extreme weather events were among the environmental factors driving population changes, the slower rise in water temperatures had a far more significant impact. The influx of warmer water drove rare and cold-water species north and welcomed new warm-water species from the south.
Rising Temperatures and its Impact
Waldman explained that demographic changes aren’t particularly detrimental to the food web and the surrounding region, but the dramatic changes caused by a half-degree increase in temperature were surprising. He noted that the data collected over 28 years is considered a short time frame in terms of geographical time, but besides mass commercial fishing, climate change is the only understood driver of population change this significant.
Future Predictions
With rising temperatures essentially “locked in,” researchers expect to continue seeing changes in the fish community and the biological community at large. Monitoring of the fish populations in Jamaica Bay is ongoing, and researchers are likely to build on this study as new data is compiled.
Conclusion
The study highlights the significant impact of climate change on Jamaica Bay’s fish ecosystem, emphasizing the need for continued monitoring and research to better understand the effects of rising temperatures on the region’s marine life.
