Mycorrhizal Fungi Associations for Taeniophyllum Orchids in Guam

189 samples from seedlings and mature Taeniophyllum marianense orchids collected across 10 sites in Guam. The dataset identifies 15 operational taxonomic units (OTUs) of orchid mycorrhizal fungi and was published by Michael Fernandez in 2026. It supports research on mycorrhizal specificity and island colonization.

Use Cases

• Analyzing mycorrhizal partner specificity based on the identified Tulasnellaceae, Ceratobasidiaceae, and Serendipitaceae OTUs.
• Studying the role of host tree species on fungal associations using samples from 26 different host trees.
• Investigating fungal community differences between seedling and mature life stages of an epiphytic orchid.
• Modeling island biogeography patterns based on the prevalence of globally distributed Tulasnellaceae partners.

Strengths

• 189 biological samples provide a substantial basis for analysis.
• Data covers 10 distinct sites and 26 host tree species, suggesting ecological breadth.
• Fungal identification used specific primers for major mycorrhizal groups, indicating a targeted methodology.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The dataset size is listed as 0.0 B, indicating a very limited scope or potential metadata issue.
