野生动物学报, 2006 野生动物不同于一般的商品,它是一种缺乏市场价格的“公共商品”。因此对野生动物价值的评估方法也不同于一般的经济学方法。本文根据国内外野生动物价值评估的研究现状,主要介绍了两种实用的野生动物价值评估方法即旅行费用法（TCM）和条件价值评估法（CVM）,并对这两种方法的优点及局限性进行了评价。

Wildlife Letters, EarlyView.Reported annual per‐capita harvest of muskrats (PCHM) decreased as wetland complexity (total number of wetland patches) decreased in 13 state and federal wetland areas in the Midwest, USA. Our results support the hypothesis that regional‐scale declines in the abundance of muskrats are likely associated with the losses to wetland habitats throughout the

Intact coastal nursery rearing amid climate‐driven phenological shifts in threatened salmon
Conservation Biology, EarlyView.Abstract Literature linking phenology to climate has proliferated in recent decades and shows that climate change has reorganized seasonal opportunities worldwide. However, this literature often quantifies changes in point measures of timing (e.g., beginnings and peaks) without context about duration (e.g., rearing season length) or performance (e.g ...
