Document Summary
Reading questions #2: the authors are interested in finding out if related juvenile salmon are clustering together and what are the factors of the clustering, and how the salmon can determine related from unrelated. They use previous research to display the importance of their study by using contrasting research, where dill 1978 showed that the salmon protected their specific territory from invaders, while armstrong, huntingford. & herbert 1999 sho(cid:449)ed that the sal(cid:373)o(cid:374) s te(cid:396)(cid:396)ito(cid:396)y o(cid:448)e(cid:396)lapped (cid:395)uite sig(cid:374)ifica(cid:374)tly. This tested to see if the dominant fish would share their food with their kin: next all the subordinate fish were separated and placed in their own aquaria. This tested to see if there was territory invasions in the absence of the dominant fish: the results for hypothesis 1 are that dominant fish will share food dense territory with their kin.
