We are particularly strong in the study of mutualisms ( cooperation both within and between species ) , but research interests span population and community ecology , conservation biology , invasion biology , behavior , ecological genetics , genomics , and speciation . The first volume of the sequence , The Golden Compass , is taken up with the competing schemes of Lord Asriel and Mrs. Coulter to understand and if possible control Dust , and with Lyra 's quest to find Roger and at the same time to convey to Lord Asriel ( funded again and back in the North ) a marvelous contraption called an alethiometer . These yucca plant and their yucca moths are the classic textbook example of " mutualism . These associations between lycaenids and ants usually benefit both partners ( known as mutualism ) . Jensen prayed in its petition that it not be required " to make any further payments to defendants pursuant to the Settlement Agreement and Mutual Release " and the covenant not to compete " be specifically enforced requiring defendants to refrain from all further association with the competing companies . But it is possible to consider the various statutory mechanisms developed to deal with the competing issues and considerations that have been discussed . " There are a few types of symbioses , commensalism , parasitism , and mutualism . Buchmann , a research entomologist , and Nabhan , author of eight books , including The Geography of Childhood ( 1994 ) , and director of science at the Arizona-Sonora Desert Museum , offer their own form of mutualism in this eye-opening and , thanks to illustrations by Paul Mirocha , eye-pleasing book . The mutualism between fungus-growing ants and their antibiotic-producing actinomycetes also has an early origin .
