The species chromatogram is a new way to show and compare the ecological niches of different species. It condenses complex environmental information into a simple two-dimensional graph, making it easier to see where species thrive and how they differ. By looking at these chromatograms, scientists can quickly figure out the best conditions for each species and how wide their range of habitats is. This method helps identify which environmental factors are most important for each species and how much they overlap in their needs. Overall, species chromatograms provide a clear picture of how different species fit into their environments and can help us understand how ecosystems work.
