Climate patternsThe patterns of variation of abiotic factors determine a climate and thus climatic adaptation. There are many different climates around the world, each with its unique patterns. Because of this, the manner of climatic adaptation shows large differences between the climates. A subarctic climate, for instance, shows daylight time and temperature fluctuations as most important factors, while in rainforest climate, the most important factor is characterized by the stable high precipitation rate and high average temperature that doesn't fluctuate a lot.[1][2] Humid continental climate is marked by seasonal temperature variances which commonly lead to seasonal climate adaptations.[3] Because the variance of these abiotic factors differ depending on the type of climate, differences in the manner of climatic adaptation are expected. ResearchResearch on climatic adaptations are mostly aimed on species living in different climates to understand which of these species would have a higher chance to survive climate change, based on their current climatic adaptations.[4][5] Climates with larger abiotic fluctuations tend to have species with a higher fluctuation tolerance, hence being able to adapt better to climate change.[6] Other research questions involve the clarification of distinct differences between relatable species such as average size and behavioral patterns.[7] Measuring Climatic AdaptationGenerally, the experimental measure of climate adaptation is conducted by exposing an experimental population to different environmental stimuli. Successful studies outside of a laboratory setting take place in locations with a variable annual climate. Areas where annual temperature and weather extremes vary greatly can give insight into the climate adaptability of organisms that live there.[8] Tropical or arctic microclimates, for example, would be ideal settings for experimentation, as annual temperature and weather can vary greatly. Additionally, laboratory settings could work with certain creatures that have defense mechanisms for certain environmental changes, such as Drosophilas chill-coma adaptation.[9] The population's performance or behavior can then be plotted against the ecological-climatic factor being tested. High changes in individual behavior in response to a change in environment point to the conclusion that the population has high climate adaptability. Adaptation lag can occur when local populations perform significantly better than populations from other environments; however, this lag can be compensated for if the species in question has very high genetic diversity. ExamplesMany species have varying levels of climatic adaptation. Differing average annual temperatures can have varying effects on a population's average body temperature, metabolic rate, or body size. But the actual effect of climatic adaptation depends greatly on the species in question and often the amount of genetic variability within that species.
