COVER PHOTO: Caught in the act, this arctic fox (Vulpes lagopus) has just taken a snow goose egg. The Arctic fox is an active forager feeding primarily on lemming and eggs of various tundra-nesting bird species during the summer. Short-term positive effects of lemmings on birds through a common predator, the arctic fox, have been documented over the circumpolar Arctic but the underlying mechanisms remain poorly understood. In their study, Beardsell et al. (this issue; Article e3734; doi:10.1002/ecy.3734) derived a mechanistic multi-prey functional response model to identify the proximate mechanisms of the short-term positive indirect effects of lemmings on tundra-nesting birds.

封面照片:这只北极狐 ( Vulpes lagopus ) 被抓获,刚刚吃了一个雪鹅蛋。北极狐是一种活跃的觅食者,在夏季主要以旅鼠和各种苔原筑巢鸟类的卵为食。旅鼠通过一种常见的捕食者北极狐对鸟类产生短期的积极影响,已在北极圈上空进行了记录,但其潜在机制仍知之甚少。在他们的研究中,Beardsell 等人。(本期;文章 e3734;doi:10.1002/ecy.3734)推导出了一个机械多猎物功能响应模型,以确定旅鼠对苔原筑巢鸟类的短期积极间接影响的近似机制。图片来源:Andréanne Beardsell。
