Environmental stressors are limited to climatic factors such as temperature and humidity.

The assignment describes environmental stress broadly. It includes climatic conditions as well as nutrition, housing, handling, transportation, disease, management techniques, and changes in day length. These factors can all require an animal to adjust to new circumstances. The statement is therefore false because it treats climate as the only source of environmental stress. **Key takeaway:** In animal bioclimatology, the animal’s environment includes management and physical conditions as well as weather.\n\n**Glossary:**\n- **Environmental stressor**: A condition or stimulus that challenges an animal’s ability to cope.\n- **Management stressor**: A challenge arising from practices such as handling or transport.
