Abstract

Orchid germination depends on their fungal partner; however, there are no broadscale analyses evaluating the actual overlap between orchids and their mycorrhizal symbionts. The aim of this research was to evaluate the importance of mycorrhizal fungi for the occurrence of two species of orchids using ecological niche modeling (ENM). Two sets of future orchid distribution models were created – the first one was based on bioclimatic data only, and the second one included information about the distribution of fungal symbionts. The jackknife test indicated that for both mixotrophic and mycoheterotrophic orchids, the presence of symbiotic fungi is crucial for their occurrence, and ENM analyses revealed that both orchids face habitat loss as a result of predicted changes in climate. In the case of the mixotrophic orchid, the presence of symbiotic fungi can compensate for unfavorable climatic conditions. Problems and limitations in modeling the distributions of species are discussed in terms of the symbiotic relationship.

混养型和霉变型兰花的长期生存和气候分布
兰花的发芽依赖于它们的真菌伙伴;然而,目前还没有大规模的分析来评估兰花与其菌根共生体之间的实际重叠情况。这项研究的目的是利用生态位建模(ENM)评估菌根真菌对两种兰花出现的重要性。研究人员创建了两套未来兰花分布模型,第一套仅基于生物气候数据,第二套包括真菌共生体的分布信息。杰克刀检验结果表明,对于混养型和绵状异养型兰花来说,共生真菌的存在对它们的出现至关重要。就混养兰而言,共生真菌的存在可以弥补不利的气候条件。从共生关系的角度讨论了物种分布建模的问题和局限性。
