A mutualism occurs between alpheid shrimp and gobiid fishes. These shrimp have poor vision but good burrowing ability. Individual shrimp share their burrows with a goby that, with good vision but no burrowing ability, acts as a watch-out warning shrimp when predators approach. In the Caribbean, a single species, Nes longus, which has been described as a mutualist, follows these behaviors. Others, such as Ctenogobius saepepallens, casually use shrimp burrows, rarely warn shrimp of danger, and are better described as commensalists. I found that N. longus more effectively avoids predators while using shrimp burrows than C. saepepallens. Thus, tight mutualism with shrimp is advantageous, especially in areas where shrimp burrows are abundant. I have quantified several behaviors that likely allow N. longus to use burrows more effectively. Why then would C. saepepallens not evolve such behaviors and become a strict mutualist if strict mutualism is advantageous? For gobies, there is likely a cost associated with mutualism with shrimp. To warn shrimp, gobies must remain at a burrow entrances and restrict foraging to that small area. I found that on the same restricted diet, C. saepepallens lost more weight than N. longus. Thus, C. saepepallens may be constrained to a casual association with shrimp due to foraging requirements. This story indicates that strict mutualism may evolve infrequently because few species can overcome the inherent costs of mutualism."},{"label":"dcterms.available","value":"2015-04-24T14:47:04Z"},{"label":"dcterms.contributor","value":"Hixon, Mark A."},{"label":"dcterms.creator","value":"Lyons, Patrick"},{"label":"dcterms.dateAccepted","value":"2015-04-24T14:47:04Z"},{"label":"dcterms.dateSubmitted","value":"2015-04-24T14:47:04Z"},{"label":"dcterms.description","value":"Department of Ecology and Evolution"},{"label":"dcterms.extent","value":"106 pg."},{"label":"dcterms.format","value":"Monograph"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/1951/59776"},{"label":"dcterms.issued","value":"2012-08-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2013-05-22T17:35:11Z (GMT).
