As the planet grapples with the consequences of human-driven climate change, the impacts on Earth’s ecosystems are becoming increasingly evident.
Among the myriad effects, the alterations in temperature, rainfall patterns, and ocean acidity are transforming the living environments for various animal species.
The Nervous System’s Crucial Role
Amid this environmental upheaval, the intricate interplay between animal nervous systems and the evolving climate emerges as a critical focus of scientific inquiry.
As a biologist and neuroscientist, my research delves into the ways animals accommodate temperature extremes and examines the factors influencing the structure and function of their nervous systems, particularly their brains.
The nervous system, responsible for crucial functions such as sense detection, mental processing, and behavior direction, plays a pivotal role in how animals respond to changing climates.

The Impact of Climate Change on Animal Senses
The ongoing changes in temperature fundamentally alter the energy balance within ecosystems, reshaping the sensory experiences of animals. From sight and taste to smell and touch, climate change is likely to challenge every aspect of animals’ sensory perception.
Special receptor proteins in the nervous systems of mammals, for instance, respond to heat and cold, influencing their ability to seek suitable habitats and respond to temperature shifts.
Climate change disrupts the environmental cues animals rely on for critical activities such as habitat selection, food foraging, and mate selection. Temperature shifts impact the orientation of animals like mosquitoes, affecting disease transmission dynamics.
Moreover, the chemical signals animals use for communication and competition can become complex due to temperature sensitivity.
Rising temperatures may disrupt the development and function of animal brains, potentially hindering their adaptability to changing environments. Research has shown that temperature extremes can affect individual neurons at genetic and structural levels, influencing overall brain organization.
In marine environments, ocean acidification induced by climate change can impact cognitive performance and sensory abilities in marine animals.
Animals respond to climate adversity by shifting locations, altering microhabitats, changing activity periods, or adjusting their geographic ranges. These behavioral shifts, driven by climate change, have far-reaching consequences, restructuring ecosystems in ways that are complex and often unpredictable.
For instance, fish in warming seas may shift to cooler, deeper waters, facing new challenges in light intensity, color range, and encounters with different species.
Animal brains are remarkably flexible, capable of adapting to individual environmental experiences and evolving in response to changing conditions.
However, studies comparing species reveal significant environmental effects on brain evolution. As climate regimes shift, natural selection is expected to favor those with new sensory or cognitive abilities, shaping the evolution of animal nervous systems.
Understanding how animal nervous systems adapt to the challenges posed by rapidly changing environments is crucial for predicting the broader impacts of climate change on all species.
As the climate continues to evolve, the intricate relationship between the environment and animal nervous systems will likely drive the evolution of new adaptive solutions, highlighting the resilience and adaptability of the natural world.
