Abstract

As truffle cultivation expands, growers empirically develop new agronomic management practices aimed at promoting truffle growth such as "truffle nests", localized peat amendments that are supplemented with truffle spore inoculum. Previous research showed that nests contain lower fungal diversity than the surrounding soil, which could encourage its occupation by pioneer species such as Tuber melanosporum. However, truffle nests did not quickly stimulate truffle mycelium growth. We hypothesized that the bacterial community from the soil may be the first to colonize nests and that fungal and bacterial diversity in nests would have an inverse relationship. To test this, we characterized the bacterial community of truffle nests, via 16S rRNA gene amplicon sequencing, in two orchards during the two years after establishing the nests. Unexpectedly, we did not find drastic differences in the bacterial diversity inside nests with respect to the bulk soil or the commercial substrate before being introduced in the field. However, Proteobacteria richness in nests was positively correlated to truffle mycelium abundance, which together with a higher relative abundance of Proteobacteria in nests than in bulk soil, indicates a possible underlying factor for the performance of nests in truffle plantations. Fungal and bacterial richness was positively correlated in nests, countering our hypothesis that bacterial diversity would negatively impact fungal diversity.

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-03-12:

  • The use, from an academic perspective evidenced by the Altmetric agency indicator referring to aggregations made by the personal bibliographic manager Mendeley, gives us a total of: 1.
  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 1 (PlumX).

With a more dissemination-oriented intent and targeting more general audiences, we can observe other more global scores such as:

  • The Total Score from Altmetric: 8.

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • The work has been submitted to a journal whose editorial policy allows open Open Access publication.
  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: http://hdl.handle.net/10532/8104
Continuing with the social impact of the work, it is important to emphasize that, due to its content, it can be assigned to the area of interest of ODS 2 - Zero hunger, with a probability of 66% according to the mBERT algorithm developed by Aurora University.
