When an alien species enters a new ecosystem, it can alter the environment in a number of ways: by eating native species (in its 50 years on Guam, the Australian brown tree snake has eliminated 9 of 13 native bird species); by spreading disease among them (introduced birds in Hawaii thrive in part because they are far less susceptible to the avian malaria parasite, also an introduced species, than native birds are); or by altering the environment in such a way that favors themselves (like melaleuca, an Australian tree that is spreading through the Everglades in part by changing the frequency and intensity of fires).

«While the changing seascape has dramatically altered and increased the diversity and number of small creatures at the base of the marine food web, we still don't know how these changes in the ecosystem will propagate through the entire chain.

«By studying the past, with the ability to see a moment in time and changes through time, we are better able to understand ecosystems and the organisms that live in them today,» Olive said.

Ocean acidification, rising ocean temperatures, declining sea ice, and other environmental changes interact to affect the location and abundance of marine fish, including those that are commercially important, those used as food by other species, and those used for subsistence.16, 17,18,122,19,20,21 These changes have allowed some near - surface fish species such as salmon to expand their ranges northward along the Alaskan coast.124, 125,126 In addition, non-native species are invading Alaskan waters more rapidly, primarily through ships releasing ballast waters and bringing southerly species to Alaska.5, 127 These species introductions could affect marine ecosystems, including the feeding relationships of fish important to commercial and subsistence fisheries.

Not only will climate change directly impact forests and the other natural systems that maintain critical water - related ecosystem services, climate impacts will be experienced largely through the medium of water — melting glaciers, changing rainfall patterns, increased water stress and drought from higher temperatures, more severe storms — resulting in increased water and food insecurity, and constraints on economic opportunity.
