Mr Healy reasoned that the main constraints on an animal's CFF are its size and its metabolic rate.

Healy先生推断，动物CFF的主要限制来自于其体型及其新陈代谢速度。

This, in essence, was the question asked by Kevin Healy of Trinity College, Dublin, in a paper just published in Animal Behaviour.

这是都柏林圣三一学院的Kevin Healy在《动物行为》上发表的论文中提出的问题的本质所在。

Fortunately for Mr Healy, this search also showed that plenty of people had looked at CFF in lots of species for other reasons.

幸运的是，对Healy先生来说，很多人为了别的原因也研究了许多物种的CFF。

Healy said, " It's pretty devastating to see all the hard work and effort you've put into removing other invasive species and translocating populations around to protect the fish and to see all that effort overturned really quickly."

“看到你为消除其他入侵物种和迁移座头鲢种群以保护座头鲢所付出的所有辛勤工作和努力被很快推翻，这令人极为震惊。”
