侵略性的互动是昂贵的，这样的个人应该显示修改侵略性，以应对环境压力。许多生物体经历频繁的食物匮乏，这可能会影响个体的能力和参与攻击的动机。然而，由于食物剥夺可以同时降低个体的资源持有潜力和增加其对食物资源的估价，其对攻击的净影响尚不清楚。在这里，我们测试的影响，越来越长的成年人的食物剥夺对雄性间的侵略对果蝇，果蝇。我们发现，男性表现出更强的侵略性后，食物剥夺时间超过一天。尽管它们的质量减少，但在食物匮乏的苍蝇中发生了攻击性增加。这一结果可能是解释了增加的吸引力，食物匮乏增加男性占用中央食物补丁，食物补丁占用积极与侵略。我们的研究结果表明，在男性的攻击策略D.黑腹果蝇的营养经验的影响，强调需要考虑过去的营养压力，以了解侵略的变化。有限的食物会降低资源持有潜力，提高资源价值。食物匮乏对攻击性的净影响尚不清楚。我们发现，成年人的食物剥夺增加侵略男性果蝇。被剥夺的男性占据食物的时间更长，这与更高的侵略。饮食压力增加了攻击性，这表明苍蝇会感到“饥饿”。
Aggressive interactions are costly, such that individuals should display modified aggression in response to environmental stress. Many organisms experience frequent periods of food deprivation, which can influence an individual's capacity and motivation to engage in aggression. However, because food deprivation can simultaneously decrease an individual's resource-holding potential and increase its valuation of food resources, its net impact on aggression is unclear. Here, we tested the influence of increasingly prolonged periods of adult food deprivation on intermale aggression in pairs of fruit flies, Drosophila melanogaster. We found that males displayed increased aggression following periods of food deprivation longer than a day. Increased aggression in food-deprived flies occurred despite their reduced mass. This result is probably explained by an increased attraction to food resources, as food deprivation increased male occupancy of central food patches, and food patch occupancy was positively associated with aggression. Our findings demonstrate that aggressive strategies in male D. melanogaster are influenced by nutritional experience, highlighting the need to consider past nutritional stresses to understand variation in aggression. Limited food can lower resource-holding potential and raise resource valuation. The net impact of food deprivation on aggression is unclear. We found that adult food deprivation increases aggression in male fruit flies. Deprived males occupied food for longer, which related to higher aggression. Dietary stress increases aggression, suggesting flies get ‘hangry’.
