Seismology is the science that studies earthquakes: its helps us predict them (at least in which regions they're likely) and gives some information to engineers of what they need to take into account when building structures in the areas prone to earthquakes.
Answer and Explanation:
Patch size appears to be the main factor that compels populations in distributed habitats. Patch size is positively related to food availability and negatively related to organic evolutionary pressures, physiological stress, and parasite charge. Habitat fragmentation and disturbance on howlers depend upon identifying different threats that may affect howlers in fragmented landscapes; specification predictions developed in fragmentation and the empirical evidence also consider during predictions. Food patch size is measured by feeding spaces, S, a patch restricted for a given animal species. Structural, spatial criteria should determine the values of S. The size of the feeding aggregate is finite by the accessibility of space or by constraining behavior. S is limited by the density of food items within the patch, and may change, depending on the relative profitability of alternative patches which is available to the animal, a result deduced from simple optimal foraging theory.
