Environmental fragmentation impacts endophytic fungi in birch leaves. Island size and distance from the mainland significantly influence fungal frequencies, with larger, closer islands supporting higher frequencies.

Area of Science:

  • Ecology
  • Mycology
  • Botany

Background:

  • Horizontally transmitted endophytic fungi inhabit plant tissues.
  • Environmental fragmentation can alter species distribution and fungal frequencies.
  • Birch trees (Betula pubescens and Betula pendula) host various endophytic fungi.

Purpose of the Study:

  • To investigate the effect of environmental fragmentation on endophytic fungal communities in birch leaves.
  • To determine the relationship between island size, distance to mainland, and fungal frequencies.
  • To identify common endophytic fungal species in the studied birch populations.

Main Methods:

  • Studied 14 islands and 5 mainland sites in an archipelago in southwestern Finland.
  • Isolated endophytic fungi from surface-sterilized leaves of Betula pubescens and Betula pendula.

Related Experiment Videos

  • Analyzed the influence of island size and distance to mainland on fungal frequency.

    • Main Results:

    • Island size explained 32-35% of the variation in endophytic fungal frequency.
    • Distance to the mainland explained 29-35% of the variation in fungal frequency.
    • Highest endophyte frequencies were observed on the largest islands closest to the mainland.

    Conclusions:

    • Foliar endophytes of birch trees can disperse across fragmented landscapes.
    • Environmental isolation and island size are key factors determining endophytic fungal frequencies.
    • Fusicladium betulae, Gnomonia setacea, and Melanconium betulinum were the most prevalent endophytic fungi.
