In an elegant analysis of resource utilization data from >500 eukaryote species, Kiørboe and Thomas (1) describe a positive relationship between the rate at which organisms acquire and ingest food. From this, they infer that “perhaps the most commonly assumed trade-off in ecology—between relative performance at low and high resource (food) levels—does not exist.” Notwithstanding the independent value of investigating trade-offs in foraging activities, we argue that this interpretation is inconsistent with the original and prevailing contemporary definition of the gleaner-opportunist trade-off (2⇓⇓–5).

拾穗，快与慢：捍卫典型的生态权衡[生物科学]


Kiørboe 和 Thomas ( 1 ) 对超过 500 种真核生物物种的资源利用数据进行了优雅的分析，描述了生物体获取和摄取食物的速率之间的正相关关系。由此，他们推断“也许生态学中最常见的假设——低资源（食物）水平和高资源（食物）水平的相对表现之间的权衡并不存在。”尽管调查觅食活动中的权衡具有独立价值，但我们认为这种解释与拾穗者-机会主义权衡的原始和流行的当代定义不一致（ 2 ⇓ ⇓ – 5 ）。
