Summary: It is important for organisms to maintain homeostasis in order to survive. Thermal regulation is an integral part of homeostasis. Organisms manage thermoregulation through behavioral and morphological adaptations. This experiment explores the behavioral adaptation of burrowing and the morphological adaptation of feather addition in a model organism. Both burying and adding feathers are predicted to help maintain homeostasis through thermoregulation. This study showed that the morphological change linked to the addition of feathers contributed to thermoregulation, unlike burrowers. Burial may not have proven beneficial in this experiment due to flaws in the experimental design. Introduction: Organisms attempt to maintain homeostasis in order to maintain their livelihoods. A major factor in homeostasis is heat loss or heat exhaustion. The thermal environment in which an organism lives has a considerable impact on the maintenance of its homeostasis. An organism can do many things to adapt to its thermal environment. For example, an organism may move to a different microenvironment that would keep it warmer or colder. Another adaptation is that an organism may use a covering such as fur or feathers to help insulate. The goal of this experiment is to explore a behavioral and morphological change that an organism can make in order to adapt to its thermal environment. It is proposed that if an organism burrows or is covered in leaves, it will retain heat more effectively. It is also proposed that if an organism is covered in feathers, it will retain heat more effectively than a naked organism. This is thought to be because the insulators in which the Burrowing Peeps were buried recently experienced rain, which effectively lowered the temperature of the surrounding soil. Plus, the sun was out, which might have warmed the naked and open Peeps. Issues like this could be resolved by further, precisely executed study. This study could be followed up by using living organisms and investigating the effect of being naked or covered in feathers/fur on thermal regulation. A living model organism could more accurately display the effects of morphological changes. There might also be improvements and follow-ups being investigated on behavioral adaptations, examining other behavioral adaptations or using more ideal conditions to test adaptations. This work is important because it shows how organisms in many different types of environments are able to regulate their body temperature..
