 The study found that penguins increased their foraging efforts when there was less food available due to environmental factors like low sea ice cover and strong winds. This resulted in reduced breeding success, which suggests that environmental variability can have a significant impact on penguin populations. As climate change increases environmental variability, this could lead to more unpredictable conditions for penguins, making it harder for them to find enough food to survive.
