Article Abstract:
A study exploring the reduction in hunting success and settlement strategies in young Spanish imperial eagles was conducted. It is proposed that young Spanish imperial eagles move from their first settlement location due to prey unavailability. When the eagle hunts, prey discontinues its normal foraging pattern thus makingthem unavailable. This would increase the hunting time for the raptors and lesstime for scouting the territory. Energy consumption and time used in the hunt will not be compensated for in the acquisition of prey.

Article Abstract:
A study exploring the choice of philopatry or dispersalin the competition for territory vacancies in the splendid fairy-wren was conducted. Results indicate that philopatry was more dominant than dispersal and that if there was dispersal, it was not more than one territory away from the natal territory. Usually, vacant dominant positions were filled by senior members of the group and outsiders could only assume the dominant position is there were no suitable replacements.

A study of the male fruit fly species revealed the major influence of developmental temperatures in the territorial success in the male of the species. Males raised at 25 degrees C displayed better paired territorial contests in comparison to males raised at 18 degrees C, despite their relative smallness in size.
