Adaptation to the local environment is crucial for organisms to survive and reproduce in the natural niche. The nematode has been studied extensively and hypothesized to be adapted to temperatures at the geographic sites where nematodes were isolated from nature. We empirically tested if this correlation is biologically meaningful by measuring the fitness of wild strains isolated from different temperatures across the Hawaiian islands. We did not observe a correlation between lifetime fecundity and the temperature of the natural niche from where the strains were isolated, indicating that this fitness trait might not be adapted to local environmental temperatures.
适应当地环境对于生物在自然生态位中生存和繁殖至关重要。对线虫进行了广泛研究，并假设其适应于从自然界分离出线虫的地理位点的温度。我们通过测量从夏威夷群岛不同温度下分离出的野生菌株的适应性，实证检验了这种相关性是否具有生物学意义。我们没有观察到菌株的终生繁殖力与分离出该菌株的自然生态位温度之间的相关性，这表明这种适应性特征可能不适应当地环境温度。
