我们提出了一种利用调查数据确定环境(栖息地)条件与海洋鱼类分布之间关系的客观方法。该方法检验了鱼类分布和栖息地条件之间随机关联的零假设。我们将这种方法应用于底深、温度和盐度数据，并对1979-84年冬春(3月)和夏季(7月)在东部斯科特陆架(西北大西洋)进行的拖网调查中的4种底层鱼(黄尾比目鱼(Pleuronectes ferrugiens，前身为Limanda ferrugina)、黑线鳕(Melanogrammus Aeglefinus)、银鳕(MerLuccius Bilinearis)和大西洋鳕鱼(Gadus Morhua))的分布进行了研究。黑线鳕和银鳕通过改变它们的水深分布(保温器)在冬季和夏季保持了相似的温度，黑线鳕的温度通常比银鳕低。黄尾比目鱼(一种深度保持器)在不同季节之间保持相似的深度，同时容忍较大的范围...
We present an objective method for identifying associations between environmental (habitat) conditions and the distributions of marine fishes using survey data. The method tests the null hypothesis of a random association between fish distribution and habitat conditions. We apply this method to bottom depth, temperature, and salinity data and to the distributions of four groundfish species (yellowtail flounder (Pleuronectes ferruginens, previously Limanda ferruginea), haddock (Melanogrammus aeglefinus), silver hake (Merluccius bilinearis), and Atlantic cod (Gadus morhua)) from trawl surveys of the eastern Scotian Shelf (northwest Atlantic) conducted in winter/spring (March) and summer (July) 1979–84. Haddock and silver hake maintained similar temperatures in winter and summer by changing their depth distributions (temperature-keepers), with haddock generally at cooler temperatures than silver hake. Yellowtail flounder (a depth-keeper) maintained similar depths between seasons while tolerating a wide range...
