M V Caiafa studies the diversity of fungi, specifically macrofungi like mushrooms, in subtropical habitats. Over nine years, they conducted extensive sampling at the Ordway-Swisher Biological Station in Florida, where they identified over 546 species of fungi. Their research highlights that fungi play a crucial role in ecosystems by helping trees absorb nutrients and decomposing dead organic material. By using DNA testing for precise identification, they created a significant reference collection to aid future research and conservation efforts.
Key findings
Identified over 546 species of macrofungi at the Ordway-Swisher Biological Station, with estimates suggesting a total of between 900 and 1,200 species.

Unearthing two new ectomycorrhizal Pezizales truffle species from Nothofagaceae forests in southern South America.
2026
Mycologia
Caiafa MV, Rowe MA, Healy R, Lemmond B, Nouhra E +4 more
Plain English Researchers discovered two new types of truffles in southern South America that grow in association with beech trees. One of these truffle species is only found in a threatened coastal forest in Chile and has only been documented three times: twice in the last few years and once over a century ago. This discovery is important because it highlights the need to protect fragile ecosystems that support unique fungi.
Who this helps: This helps conservationists and environmental scientists working to protect biodiversity in threatened forests.
Beyond Predators: Carnivores as Secondary Dispersers of Mycorrhizal Fungi.

Ecology letters
Stephens RB, Moll RJ, McGraw AM, Caiafa MV, Smith ME +3 more
Plain English This study looked at how meat-eating animals, like foxes and coyotes, help spread mycorrhizal fungi, which are important for plant growth. Researchers found that these predators helped move the fungi's spores around, with larger predators spreading them farther, though they dropped fewer spores overall. This is important because it shows that carnivores play a key role in maintaining healthy ecosystems by helping fungi reach new areas.
Who this helps: This research benefits ecologists and conservationists working to protect ecosystems.
Think globally, barcode locally: nine years of macrofungi sampling reveals extensive biodiversity at the ordway-swisher biological station, a subtropical site in Florida.
Plain English Researchers spent nine years cataloging mushrooms and other large fungi at a Florida nature preserve, identifying over 546 species and estimating the actual total is probably between 900 and 1,200 species—meaning there are more fungal species at this one site than there are vertebrate animals or plants. They used DNA testing to precisely identify each specimen and created a reference collection for future research.
This matters because fungi are essential to forest ecosystems (they help trees absorb nutrients and break down dead material), yet scientists know far less about fungal diversity than they do about plants and animals, making this comprehensive catalog a crucial foundation for understanding and protecting Florida's ecosystems.
Soil microbiome feedbacks during disturbance-driven forest ecosystem conversion.
2024
The ISME journal
Nelson AR, Fegel TS, Danczak RE, Caiafa MV, Roth HK +7 more
Plain English This study looked at how disturbances like pile burning in forests affect the soil's microbiome and the plant life above it. Researchers found that right after pile burning, the diversity of certain beneficial fungi in the soil dropped, which likely hurt the growth of tree seedlings and allowed more herbaceous (non-woody) plants to thrive. Six decades later, the soil's microbial communities started to resemble those of the surrounding forest again, suggesting that while there were initial negative effects, the microbes showed resilience over time.
Who this helps: This benefits ecologists and land managers focusing on forest restoration after disturbances.
Wildfire impact on soil microbiome life history traits and roles in ecosystem carbon cycling.

ISME communications
Nelson AR, Rhoades CC, Fegel TS, Roth HK, Caiafa MV +3 more
Plain English This research studied how wildfires affect the tiny organisms in soil, called microbes, which are important for breaking down carbon and nitrogen. The team found that severe wildfires favor fast-growing microbes at first, and over the next ten years, these microbes adapt to utilize a variety of resources, which can lead to more carbon being lost from the soil. Understanding these changes is crucial because it helps predict how wildfires and climate change will impact soil health and the environment.

Ectomycorrhizal fungal communities associated with Crocanthemum and Lechea (Cistaceae) in subtropical Florida sandhill habitats.

Mycorrhiza
Caiafa MV, Grazziotti PH, Karlsen-Ayala E, Jusino MA, Healy R +3 more
Plain English This study examined the types of fungi that live in partnership with two plants, Crocanthemum and Lechea, in sandy, fire-prone areas of Florida. Researchers found that these plants mostly hosted fungi from two groups: Cenococcum and Russula, with some fungi from the Delastria group also present. Although some fungi were shared with nearby pines, the fungal communities associated with Crocanthemum and Lechea were still notably different from those found with the pines.
Who this helps: This research is beneficial to ecologists and conservationists studying plant-fungi relationships in unique ecosystems.
Plain English This research focused on a type of truffle known as Amylascus, which is found in Australia and South America. The scientists discovered that there are more species of Amylascus than previously recognized, identifying two known species and seven new ones, including five from South America. This finding is significant because it enhances our understanding of biodiversity in these regions and shows that some truffles may be more common than we thought, despite them being rarely observed in nature.
Who this helps: This benefits researchers studying biodiversity and the ecosystems in which these truffles exist.

Current biology : CB
Caiafa MV, Jusino MA, Wilkie AC, Díaz IA, Sieving KE +1 more
Plain English This study looked at how certain birds in Patagonia help spread truffles and other fungi by eating them and then passing the spores in their droppings. Researchers found that two common bird species, the chucao tapaculo and the black-throated huet-huet, regularly eat these fungi and effectively disperse their spores, which benefits the trees and plants in their environment. Specifically, the birds consumed a variety of mycorrhizal fungi, supporting the growth of around 30 different types, which help trees in the forest get nutrients.
Who this helps: This research helps environmental scientists and conservationists understand the important role of birds in forest ecosystems.
