Document Summary
Seen how the physical environment in uences the biology and distribution of marine organisms that we will survey this semester. Biology and distribution of marine organisms in uenced by: ecological interactions, evolutionary history. Ecological interactions consist of interactions between an organisms and: abiotic features: physical environment, biotic features: other organisms. Can be viewed as hierarchical: 1. Where marine organisms (which is mostly what"s studied in class) occur in the ocean. 1/27/17 - 1/30/17 are related to 3 major phenomenon: a. habitat - environmental conditions, b. homeostasis - ability to tolerate the environment, c. biogeography - in uence of evolutionary on distribution of population. Habitat: speci c place in environment where an organism lives, marine habitats characterized by certain physical features: Microhabitats: subdivisions within larger habitats (subtidal, intertidal, supratidal, also have their own set of physical characteristics, often on very small scale. Both large and small scale habitat characteristics in uence what types of organisms are found there.
