Interactions between Ecological Traits and Host Plant Type Explain Distribution Change in Noctuid Moths

摘要: The ecological traits of species determine how well a can withstand threats to which it is exposed. If these predisposing be identified, that are most at risk decline identified and an understanding the processes behind declines gained. We sought body size, specificity larval host plant, overwintering stage, type interactions related distribution change in noctuid moths. used data derived from literature analyzed effects both separately simultaneously same model. When we separately, seemed important determinants were stage plant. Nevertheless, often correlated independent effect each trait may not seen analyses separately. accounted for other traits, results substantially different. Only one (body size), but 3 interactions, explained change. This finding suggests determined by 1 or 2 traits; rather, depends on interacting traits. Such complexity makes difficult understand changes emphasizes need basic knowledge species. With such knowledge, more accurate picture factors causing increasing extinction might attainable.
