“…Restoration of habitats and the application of conservation measures does appear to sustain palm fungi, such as those collected on palms in secondary forests in Hong Kong ( Fröhlich & Hyde, 2000). This has also been demonstrated for soil fungi from previously undisturbed tropical habitats ( Rambelli et al. , 1983 ; Rambelli et al.…”

The microfungi of three palm species were investigated in their natural habitats and in habitats where the palms were cultivated outside their natural ranges. The palms that were selected differed in their habitats and ecology. Archontophoenix alexandrae is endemic to tropical rainforests in Australia, Cocos nucifera is pan‐tropical and Trachycarpus fortunei occurs in warm‐temperate China. Different assemblages of fungi were found in association with palms in temperate regions as compared to those in tropical regions. These differences were more related to climatic influences than to the hosts sampled, as few fungi were host‐species specific. The status of the hosts at the site, i.e. indigenous or introduced, and the degree of disturbance of the habitats within which the palms grew were also influential. When sampled in its natural habitat, Archontophoenix alexandrae had a distinct palmicolous mycota typical of other palms in tropical rainforests. Outside of the palm’s natural habitat, a widely different mycota were recorded that comprised tropical species of a more plurivorous nature. A similar plurivorous assemblage characterized the fungi associated with Cocos nucifera, probably due to the palm’s long history of cultivation. Similarly, plurivorous, but temperate or widespread fungi were associated with Trachycarpus fortunei, both within and outside of its natural habitat. This palm is also highly cultivated. A reduction in palm fungi associated with palms in disturbed habitats has implications for conservation of these fungi. However, it is acknowledged that the data for fungal diversity and distribution is incomplete and fragmentary.

“…Even in tropical forests many taxa are similar to taxa found in temperate latitudes, and the numbers of species for a particular tropical soil are normally the same or even lower than those observed for soils in temperate regions (Pfenning 1997;Bettucci and Roquebert 1995). Needless to say that the species diversity in the litter layer is considerably higher and many novelties have resulted, e.g., from voluminous studies carried out in Ivory Coast (Rambelli et al 1984(Rambelli et al , 2004.…”

This survey is concerned only with filamentous fungi living in the soil layer. The observed diversity of soil fungi largely depends on the method used and the numbers of isolates obtained. Particle-plating usually yields higher numbers of taxa than dilution plating. The Centraalbureau voor Schimmelcultures (CBS) preserves a great diversity of soil fungi. The CBS database contained 2,210 species of soil fungi in 2001, an estimated 70% of the known species available in culture. Thus, the current estimate for described culturable soil fungi is approximately 3,150 species, many of which have a cosmopolitan distribution. Adding the ca. 150 spp. of nonculturable Glomerales results in 3,300 species of currently known soil fungi. Molecular studies in such groups as Fusarium, Trichoderma, Penicillium, and Aspergillus are finding a number of more narrowly distributed cryptic species. Thus the number of species of soil fungi is expected to be considerably higher than the 3300 species currently known.

“…Studies on fungal diversity in tropical soils have concluded that the cultivation soil can alter the abundance of some members of the soil fungal community [28][29][30]. However, soil fungal communities have recovered relatively quickly after fallow [31].…”

Abstract:The processes of land conversion and agricultural intensification are a significant cause of biodiversity loss, with consequent negative effects both on the environment and the sustainability of food production. The anthrosols associated with pre-Colombian settlements in the Amazonian region are examples of how anthropogenic activities may sustain the native populations against harsh tropical environments for human establishment, even without a previous intentionality of anthropic soil formation. In a case study (Model I-"Slash-andBurn") the community structures detected by automated ribosomal intergenic spacer analysis (ARISA) revealed that soil archaeal, bacterial and fungal communities are heterogeneous and each capable of responding differently to environmental characteristics. ARISA data evidenced considerable difference in structure existing between microbial communities in forest and agricultural soils. In a second study (Model II-"Anthropogenic Soil"), the bacterial community structures revealed by terminal restriction fragment length polymorphism (T-RFLP) differed among an Amazonian Dark Earth (ADE), black carbon (BC) and its adjacent non-anthropogenic oxisoil. The bacterial 16S rRNA gene (OTU) richness estimated by pyrosequencing was higher in ADE than BC. The most abundant bacterial phyla in ADE soils and BC were Proteobacteria-24% ADE, 15% BC; Acidobacteria-10% ADE, 21% BC; Actinobacteria-7% ADE, 12% BC; Verrucomicrobia, 8% ADE; 9% BC; Firmicutes-3% ADE, 8% BC. Overall, unclassified bacteria corresponded to 36% ADE, and 26% BC. Regardless of current land uses, our data suggest OPEN ACCESSDiversity 2010, 2 788 that soil microbial community structures may be strongly influenced by the historical soil management and that anthrosols in Amazonia, of anthropogenic origins, in addition to their capacity of enhancing crop yields, may also improve microbial diversity, with the support of the black carbon, which may sustain a particular and unique habitat for the microbes.
