摘要

摘要:本文利用婆罗洲、巴拉望岛和菲律宾群岛其余地区的物种组成模式，考虑赫胥黎对华莱士线的修改是否代表了影响黏菌分布的区域边界。其中，婆罗洲黏菌的分类多样性最高，分别为56种(TDI = 2.67)和159种(TDI = 4.18)，共有黏菌16属30种，TDI = 1.88。在物种组成上，婆罗洲与巴拉望岛(群落系数CC = 0.395)的相似性大于与菲律宾(0.254)的相似性。然而，巴拉望岛更像大洋洲菲律宾(0.502)，而不是婆罗洲。这表明婆罗洲和巴拉望在黏菌的物种组成方面具有一定的亲和力，但与婆罗洲相比，巴拉望似乎与菲律宾群岛的其余部分具有更高的群落相似性。因此，就物种组成而言，黏菌似乎与赫胥黎线所划定的生物地理区域不一致。

Does Huxley's Line Apply to Myxomycetes?

Abstract: This paper considers whether Huxley's modification of the Wallace line represents a regional boundary affecting distribution in myxomycetes, using patterns of species composition from the territories of Borneo, Palawan, and the remainder of the Philippine archipelago. With a total of 30 species of myxomycetes belonging to 16 genera (taxonomic diversity index, TDI = 1.88), Borneo recorded the highest taxonomic diversity compared to Palawan with 56 species (TDI = 2.67) and the oceanic Philippines with 159 species (TDI = 4.18). Based on species composition, Borneo is more similar to Palawan (coefficient of community, CC = 0.395) than it is to the oceanic Philippines (0.254). However, Palawan is more similar to oceanic Philippines (0.502) than it is to Borneo. This suggests that Borneo and Palawan have a certain affinity in terms of species composition of myxomycetes, but Palawan still seems to have a higher community similarity to the remainder of the Philippine archipelago when compared to Borneo. Therefore, in terms of species composition alone, myxomycetes do not appear to concur with the biogeographic region delineated by Huxley's line.

期刊介绍： Pacific Science: A Quarterly Devoted to the Biological and Physical Sciences of the Pacific Region The official journal of the Pacific Science Association. Appearing quarterly since 1947, Pacific Science is an international, multidisciplinary journal reporting research on the biological and physical sciences of the Pacific basin. It focuses on biogeography, ecology, evolution, geology and volcanology, oceanography, paleontology, and systematics. In addition to publishing original research, the journal features review articles providing a synthesis of current knowledge.
