Scientific collections are organized groups of specimens or data that are used for research and education in various fields of science. These collections can include items like plants, animals, minerals, and fossils, which are often preserved and cataloged for study. They help scientists understand biodiversity, evolution, and environmental changes over time. Many scientific collections are housed in institutions such as museums, universities, and research centers. They serve as valuable resources for researchers, allowing them to conduct experiments, make comparisons, and share knowledge. Collections also play a crucial role in conservation efforts by providing data that can inform policies and practices to protect endangered species and habitats.
