Understanding the intricate dance between predator and prey populations is a fundamental challenge in ecology. The dynamics are rarely simple, often influenced by a multitude of factors, including resource availability and environmental conditions. One particularly important factor is temperature, which can significantly impact both predator and prey survival, reproduction, and behaviour. Fluctuations in temperature can disrupt the delicate balance, leading to unexpected population shifts and potentially even ecosystem collapse.

For instance, rising temperatures may increase the metabolic rate of prey animals, demanding more food to sustain themselves. If their food sources are limited, or if predator metabolism also increases, we may see an increase in prey mortality or changes in predator-prey ratios. This interconnectedness is illustrated in various ecological models, highlighting the complex relationship between species interactions and environmental change.

Conversely, fluctuations in temperature could impact the reproductive success of both predator and prey. Extreme cold snaps or extended heatwaves can negatively influence reproductive rates in multiple species. The effect can differ from one species to another depending on the environmental preferences or adaptabilities of both predator and prey species. We have detailed discussion on these specific points within this article; please review this more Predator Reproduction Rates and Fluctuating Temperature.

Furthermore, shifts in temperature can influence the geographic ranges of both predators and prey. As suitable habitats change, species might migrate in search of better environments or attempt to adapt in place, changing the overall interaction patterns and impacting the population dynamics.

While understanding predator-prey dynamics under stable conditions is crucial, studying their response to climate change, represented here by fluctuating temperatures, is crucial to predict and prepare for future ecological disruptions. For more information on modeling such responses, one good place to look is this insightful article published by Nature Communications.

Ultimately, unraveling the complexities of predator-prey interactions under varying temperatures is critical for effective conservation and management strategies for multiple ecosystem services, and requires thorough investigation using various mathematical and experimental methods.
