检验了理想自由分布(IFD)的两个主要假设，IFD是一个预测生物在斑块资源中均衡分布的最优觅食模型。对自由生活的绿头鸭种群进行了一项实验，这些鸭子经过训练，在12天内每天早上的特定时间聚集在研究地点。面包在相隔约16米的食物地点以高和低的比率分发。结果显示，与IFD对栖息地匹配的预测有显著偏差。由于知觉限制对理想假设的违反被认为是偏离IFD的主要原因。(保留所有权利)
Tested 2 major assumptions of the ideal free distribution (IFD), an optimal foraging model, which predicts the equilibrium distribution of organisms among patch resources. An experiment was performed with a free-living population of mallard ducks that were trained to congregate at the study site at a specific time each morning over 12 days. Bread was distributed at a high and low rate at food sites about 16 m apart. Results show a striking deviation from the IFD's prediction of habitat matching. Violations of the ideal assumption due to perceptual constraints are concluded to be a major cause of departures from the IFD.(PsycINFO Database Record (c) 2017 APA, all rights reserved)
