9Occupancy-abundance relationship — In macroecology, the occupancy abundance (O A) relationship is the relationship between the abundance of species and the size of their ranges within a region. This relationship is perhaps one of the most well documented relationships in… …
10Biostratigraphy — is the branch of stratigraphy which focuses on correlating and assigning relative ages of rock strata by using the fossil assemblages contained within them. Usually the aim is correlation, demonstrating that a particular horizon in one geological …
