Answer :
Based on the given data, we can observe a trend in increasing water temperatures off the coast of Virginia over the decades:
- In 1970 and 1980, the average summer water temperature was [tex]\(15^{\circ}C\)[/tex].
- In 1990, it increased to [tex]\(16^{\circ}C\)[/tex].
- By 2000, it reached [tex]\(17^{\circ}C\)[/tex], which is the temperature flounder are best adapted to in the summer.
- In both 2010 and 2020, the temperature increased further to [tex]\(18^{\circ}C\)[/tex].
The data shows a clear upward trend in water temperature over the past five decades. Hereâs a step-by-step analysis of what this means for the summer population of flounder around Virginia:
1. Optimal Temperature: Flounder are best adapted to water temperatures near [tex]\(17^{\circ}C\)[/tex]. They thrive best when the environment aligns closely with this temperature.
2. Historical Data Analysis:
- For the decades of 1970 and 1980, the temperature was [tex]\(15^{\circ}C\)[/tex], which is slightly cooler than optimal, but still within a potentially tolerable range for the flounder.
- In 1990, the temperature warmed to [tex]\(16^{\circ}C\)[/tex], getting closer to the optimal [tex]\(17^{\circ}C\)[/tex] for flounder.
- By 2000, the temperature reached [tex]\(17^{\circ}C\)[/tex], which is the ideal condition for the flounderâs summer habitat.
- However, from 2010 onwards, the temperature rose to [tex]\(18^{\circ}C\)[/tex], which is warmer than the optimal [tex]\(17^{\circ}C\)[/tex].
3. Future Predictions:
- If the trend continues, the temperature may continue to rise above [tex]\(18^{\circ}C\)[/tex] in the subsequent decades.
- Flounder populations may begin to experience stress or reduced suitability in their habitat as the water temperature exceeds their optimal range.
4. Genetic Adaptations and Population Impact:
- Flounder may have some tolerance to temperature changes, but sustained temperatures above their optimal [tex]\(17^{\circ}C\)[/tex] can lead to reduced reproductive success and survival rates.
- Over time, if the temperature continues to increase, itâs likely that the summer population of flounder around Virginia would decline as the conditions become less favorable.
- Furthermore, flounder might migrate further north, where water temperatures may be closer to their preferred [tex]\(17^{\circ}C\)[/tex], thereby decreasing their presence around Virginia in the summer months.
5. Conclusion:
- Given the trend of increasing water temperatures from 1970 to 2020, and considering that optimal conditions for flounder are around [tex]\(17^{\circ}C\)[/tex], it can be predicted that the summer population of flounder around Virginia will decline in the coming decades if the trend continues.
- This prediction underscores the importance of monitoring water temperature changes and their impact on marine life, particularly species with specific environmental adaptabilities like flounder.
In summary, as water temperatures continue to rise, itâs likely that the summer population of flounder around Virginia will decrease due to the less favorable conditions, forcing them to migrate to cooler waters further north.
