How will climate change affect individuals’ welfare, directly (e.g. extreme weather) and indirectly (e.g. changes in habitat quality?
Context and Relevance:
Climate change poses both direct and indirect threats to wild animals, significantly affecting their welfare. Direct impacts include extreme weather events such as heatwaves, wildfires, floods, and droughts, which can cause injury, displacement, or death. Indirectly, climate change can degrade habitats, alter food availability, disrupt migration patterns, and lead to increased competition with other species. Understanding these impacts is critical in wild animal welfare science, where the focus is on improving the lives of individual animals in the wild.
Potential Research Approach:
Understanding the Direct Welfare Impacts of Climate Change: Research should assess how extreme weather events impact wild animals on an individual level, focusing on the physiological and psychological stress caused by heat, cold, or natural disasters. Field studies could track mortality rates, injuries, and behavioral responses to changing climates. Specific focus on species most vulnerable to these events, such as amphibians during droughts or birds during hurricanes, would help identify key welfare challenges.
Investigating Indirect Effects on Habitat Quality: Changes in habitat quality due to rising temperatures, altered precipitation patterns, and shifting ecosystems can lead to reduced shelter, food, and safety for wild animals. Research should focus on the long-term effects of habitat degradation, including how animals adapt to new environments or struggle with limited resources. Case studies examining how species like polar bears or coral reef fish are affected by diminishing habitats will be crucial to developing intervention strategies.
Studying Increased Competition and Predation :As species migrate or expand their ranges in response to climate shifts, they come into conflict with others for resources, leading to increased competition. Research should explore how these conflicts affect welfare, including increased stress, starvation, or injury. Additionally, changing predator-prey dynamics—such as the rise in predator populations due to milder winters—can negatively impact prey species, increasing the need for interventions to maintain balance.
Monitoring Changes in Species Behavior and Welfare
Research should track how wild animals modify their behaviors in response to climate change, such as altered migration patterns, breeding cycles, or feeding habits. These behavioral changes could lead to both positive and negative welfare outcomes, and understanding them will provide insight into which species are more resilient and which are most at risk. Monitoring these changes is crucial for developing adaptive management practices that support individual welfare.
