Long-standing theory predicts that the intensity of biotic interactions increases from high to low latitudes. Studies addressing geographic variation in predation on insect prey have often relied on prey models, which lack many characteristics of live prey. Our goals were to explore global latitudinal patterns of predator attack rates on standardised live insect prey and to compare the patterns in predation on live insects with those on plasticine prey models.

对活体和人工昆虫猎物的捕食表现出不同的整体纬度模式


长期以来的理论预测，生物相互作用的强度从高纬度到低纬度增加。解决昆虫猎物捕食地理差异的研究通常依赖于猎物模型，而猎物模型缺乏活猎物的许多特征。我们的目标是探索标准化活体昆虫猎物的捕食者攻击率的全球纬度模式，并将活体昆虫的捕食模式与橡皮泥猎物模型的捕食模式进行比较。
