Mycorrhizal arbitrage, a hypothesis: How mycoheterotrophs could profit from inefficiencies in the biological marketplace

Functional Ecology, Volume 39, Issue 6, Page 1431-1440, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Mycoheterotrophy, whereby plants acquire both carbon and nutrients from a fungal partner, is an evolutionarily puzzling phenomenon. According to biological market models, mycoheterotrophs have nothing to offer and thus should be shunned as trading partners by ...

Context‐dependent effects of below‐ground carbon transfer: Limited benefits from sunlit pines to shaded oaks

Functional Ecology, Volume 39, Issue 6, Page 1369-1383, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Despite gaining significant attention in recent years, it remains unclear whether mycorrhizal fungi distribute meaningful amounts of resources among trees in ways that increase the fitness of the receiving trees. To investigate this, we used pairs of shaded and unshaded

ANALYSIS OF THE POST‐INFECTION GROWTH STIMULUS IN ORCHID MYCORRHIZA [PDF]

New Phytologist, 1971
SummaryThe sequence of symbiotic infection of Dactylorhiza purpurella protocorms shows that commencing shortly after infection there is a linear increase in length and breadth whereas growth of uninfected protocorms is negligible.From the time when external hyphae make physical contact with epidermal hairs of the host the processes of penetration ...

Patterns of Functional Diversity, Species Diversity, and Endemicity Driven by Elevation and Topographic Complexity in a Mediterranean Mountain Refuge

Ecology and Evolution, Volume 15, Issue 5, May 2025.
Within the scope of our study, we modeled and mapped the relationships between functional diversity (Rao's Q), alpha species diversity, and endemism with topographic and climatic factors in a mountainous refugial area encompassing all Mediterranean vegetation strata.

The Increased Environmental Niche of Dual‐Mycorrhizal Woody Species

Ecology Letters, Volume 28, Issue 5, May 2025.
Abiotic factors influence the global distribution of mycorrhizal host plants (ectomycorrhizal fungi and arbuscular mycorrhizal fungi), raising the possibility that dual associations with both mycorrhizal types may enhance species' distribution range and environmental niche space.

Isolation and identification of beneficial orchid mycorrhizal fungi in Paphiopedilum barbigerum (Orchidaceae)

Plant Signaling & Behavior, 2022
Seed germination and seedling development in nearly all orchid species rely on a symbiotic relationship with mycorrhizal fungi; however, this is not the case with all mycorrhizal fungi. This study aims to provide an understanding about the important role

Darwin’s prescient letter regarding orchid mycorrhiza

Lankesteriana: International Journal on Orchidology
On March 26, 1863, Charles Darwin wrote a letter to Joseph Dalton Hooker, describing his attempts to germinate orchid seeds. In this letter, he mentioned his hope to observe orchid seedlings and expressed a “notion that [the seeds]. . . are parasites in early youth on cryptogams!!”.

Native and exotic Juglans nigra seedlings recruit distinct mycobiomes that differentiate with emergent disease variation

Ecosphere, Volume 16, Issue 4, April 2025.
Abstract Under global change, the transformation of landscapes and anthropogenic movement of organisms lead to novel biotic interactions that affect ecosystem health. A prior field‐based metabarcoding survey revealed that Juglans nigra harbors a novel, low‐diversity mycobiome outside of its native range that may contribute to the severity of thousand ...

Productivity, moisture and competition—Habitat conditions affecting population viability of the wet grassland orchid Dactylorhiza majalis under conservation‐oriented management

Journal of Applied Ecology, Volume 62, Issue 4, Page 970-985, April 2025.
Our results suggest that adjusting regular conservation‐oriented management may be beneficial for many wet grassland sites. Observing few but large D. majalis individuals may serve as a warning sign for deteriorating site conditions that can help prioritise conservation efforts to stabilise populations early on.
