Entomology
Entomology is the study of insects and their relationship to humans, the environment and other organisms ([1] Entomology Department, WSU.) Entomologist provide a diverse range of services to many different occupations. For example, forensic entomologists, a specific branch of entomology, would work to better understand a criminal case, such contributing to solving a murder by figuring out the type of insects that are decomposing the remains. This may provide insight to how long a body has been decomposing or if the remains were moved.
Entomology is a part of the study of ecology and human geography and it can also be used as indicators of environmental shifts or changes. Insects are important to a forests biodiversity and slight climate shifts can cause damages to an ecosystem. For example, an invasive species of insect can be introduced to an ecosystem due to a shift in climate and this can cause flora to disappear. Also, entomology can be used in studying specific types of flora to an ecosystem, which may help to better understand the type of insects within a region. An example of this would any pollinating insects.
Entomology is used in many fields and can be used to better understand areas of study such as terrestrial ecology and essential ecosystem services.
