摘要

随着气候逐渐向北变得更加严酷,加拿大昆虫动物群的多样性减少,其组成(在所有分类水平上)也发生了变化。这种气候趋势支配着多样性的模式,但许多其他因素相互作用产生了观测到的模式。在北极,物种丰富度在西部最大。再往南,总体物种丰富度在西部(特别是不列颠哥伦比亚省)是最大的,与沿海和科迪勒栖息地有关,而在东南部(特别是安大略省),与落叶林有关,特别是与占据加拿大东南部大片地区的过渡森林有关。然而,某些分类群在西部或东部有更好的代表性,这取决于当今的栖息地和历史因素。这些结论主要是基于不同类型分类群的样本得出的,之所以有可能,是因为已经进行了基本的系统工作来区分和绘制物种。关于数值模式的初步数据,例如相对于不同潜在资源(如不同地区的寄主植物)的物种数量,往往表明北方物种的发生可能严重依赖于气候因素,以至于潜在资源没有得到充分利用,种间相互作用对多样性的影响也降低了。

PATTERNS OF DIVERSITY IN THE CANADIAN INSECT FAUNA
The diversity of the Canadian insect fauna decreases and its composition (at all taxonomic levels) changes as climates become progressively more harsh toward the north. This climatic trend dominates patterns of diversity, but many other factors interact to produce the observed patterns. In the arctic, species richness is greatest in the west. Farther south, overall species richness is greatest in the west (especially British Columbia), associated with coastal and cordilleran habitats, and to a somewhat smaller degree in the southeast (especially Ontario), associated with deciduous forests and particularly with transitional forests which occupy a large area of southeastern Canada. However, certain taxa are better represented in the west or in the east, depending on present-day habitats and on historical factors. These conclusions, based chiefly on a sample of taxa of different types, are possible only because basic systematic work has been carried out to distinguish and map the species. Preliminary data on numerical patterns, such as the numbers of species relative to different potential resources such as host plants in different zones, tend to suggest that the occurrence of species in the north may depend so heavily on climatic factors that potential resources are not fully exploited and the effects of interspecific interactions on diversity are reduced.
