What is one major effect of climate change on wildlife?

One major effect of climate change on wildlife is that it can disrupt migration patterns and breeding seasons. Changes in temperature and weather patterns can alter the timing and routes of animal migrations, which are often closely tied to seasonal variations in food availability, breeding opportunities, and habitat conditions. For instance, as temperatures rise and seasons shift, some species may find their traditional migratory routes and breeding grounds no longer suitable, leading to mismatches in food supply and breeding timing. This disruption can have significant repercussions on population dynamics, species interactions, and overall biodiversity.

In contrast, the other options do not accurately reflect the complexities of climate change's impacts on wildlife. The assertion that climate change uniformly enhances wildlife population growth overlooks the variety of stressors that many species face, making it unlikely for all to thrive. Additionally, the claim that climate change has no measurable impact on ecosystems is not supported by extensive scientific research that has documented significant changes in habitats and species distributions. Lastly, while invasive species may benefit from climate change in some scenarios, the idea that it exclusively benefits them disregards the multitude of native species that also face challenges and potential declines, emphasizing the need for a more nuanced understanding of these ecological shifts.
