King Abdullah of Jordan, an important American ally in the Arab world, called poor nations "breeding grounds for conflict" between "Western haves and worldwide have-nots".
Corruption, inequality and the return of nationalism are breeding grounds for conflict, and the events of last week demonstrate that none of us is immune from the ghastly consequences of modern warfare.
In polygynous mammals, intrasexual aggression typically differs between the sexes, with males coming into conflict over breeding opportunities while females come into conflict over resources such as food and space (Thouless & Guinness 1986; Festa-Bianchet 1991).
For males of breeding age, the conflict-ridden mating season brings injury, exhaustion and even death as they aggressively defend territory and females from their rivals.
The presence of weak states in the system also constitutes a destabilizing feature of the international system due to the fact that weak states are likely to become either revisionist in nature or breeding places for armed conflicts and illegal activities of every kind, while their very existence may evoke a desire to conquer in strong states with offensive security strategies.
More recent advances have often had the opposite effect, breeding isolation and sometimes even conflict (like the remote control, the MP3 player and SportsIllustrated.com).
Only recently, however, have researchers started to explore the implications of sexual conflict on speciation, breeding systems, and evolution of various life-history traits [ 4- 7].
Taken together, the comparison between two closely related species with contrasting breeding systems suggest that sexual conflict over care has influenced the evolution of behavior and morphology in penduline tits.
Thus, including mate choice in breeding management appears to directly conflict with current management goals that aim to minimize the loss of genetic variation and adaptation to captivity (Asa et al. 2011): adding an additional level of complexity in determining the best breeding strategy for captive populations (see above).
