Population viability of the orchid Gymnadenia conopsea increases with population size but is not related to genetic diversity

Journal of Ecology, Volume 113, Issue 3, Page 635-648, March 2025.
Population viability of the long‐lived orchid Gymnadenia conopsea increased with population size, but not with genetic diversity. Larger populations had higher and more stable adult survival, suggesting favourable habitats that buffer effects of climatic variation.

Orchid Mycorrhizal Communities Associated With Orchis italica Are Shaped by Ecological Factors and Geographical Gradients

Journal of Biogeography, Volume 52, Issue 3, Page 544-557, March 2025.
ABSTRACT Aim The influence of mutualists on plant distributions is only beginning to be understood. Orchids depend on orchid mycorrhizal (OrM) fungi to germinate, yet the distribution of OrM fungi and how they vary according to both abiotic and biotic factors is unclear.

Identification of pollinators of lesser twayblade Neottia cordata with DNA barcoding reveals strong links with pine forest‐related fauna

Nordic Journal of Botany, Volume 2025, Issue 3, March 2025.
Many European terrestrial orchids are in decline. To curb this negative trend and preserve remaining populations, more ecological knowledge is needed. Surprisingly little is known yet about the identity and efficiency of pollinators of lesser twayblade Neottia cordata, a small terrestrial orchid species associated with pine trees through joint ...

The Diversity and Growth-Promoting Potential of the Endophytic Fungi of Neuwiedia singapureana (Orchidaceae) in China

Diversity
Neuwiedia singapureana is a rare and endangered plant of the Apostasioideae subfamily. The Apostasioideae subfamily has a unique evolutionary status, as it is considered to be the most primitive group forming the base of the Orchidaceae evolutionary tree.

Regional-scale in-depth analysis of soil fungal diversity reveals strong pH and plant species effects in Northern Europe [PDF]

, 2020
Soil microbiome has a pivotal role in ecosystem functioning, yet little is known about its build-up from local to regional scales. In a multi-year regional-scale survey involving 1251 plots and long-read third-generation sequencing, we found that soil pH

Mycorrhizal specialization toward each distinct Oliveonia fungus in two closely related photosynthetic Dactylostalix orchids

Functional Ecology, Volume 39, Issue 1, Page 199-208, January 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Although rhizoctonias from Ceratobasidiaceae, Tulasnellaceae and Serendipitaceae are typical orchid mycobionts, orchid mycorrhizal fungi exhibit vast taxonomic and ecological diversity.

Stable Isotope Signatures Illuminate Diverse Nutritional Strategies in Rhizoctonias and Their Orchid Partners

Plant, Cell &Environment, Volume 48, Issue 1, Page 792-804, January 2025.
ABSTRACT Understanding the nutritional ecology of orchids, particularly those in symbiosis with rhizoctonias, presents a complex challenge. This complexity arises partly from the absence of macroscopic fruit bodies in rhizoctonias, which impedes the acquisition of their stable isotope data.
