Special Issue Information

Dear Colleagues,

Bryophytes and lichens are among the most diverse groups of land plants, playing an indispensable role in forest ecosystems—these tiny organisms contribute significantly to essential ecological functions such as water retention, nutrient cycling, and soil stabilization, while also providing habitats for various species. Despite their critical importance, they have often been overlooked in ecological research.

This Special Issue aims to explore the diversity, ecological functions, and interactions of bryophytes and lichens within forest ecosystems. We welcome original research, review articles, and case studies focusing on the following topics:

  • The role of bryophytes and lichens in soil and water retention in forests;
  • Their impact on forest biodiversity and ecological stability;
  • The symbiotic relationships between bryophytes, lichens, and trees;
  • The effects of climate change on these communities and their adaptive mechanisms;
  • The application and potential of bryophytes and lichens in ecological restoration.

By gathering these research contributions, we seek to enhance the understanding of the importance of bryophytes and lichens in forest ecosystems and provide new perspectives for future research. We encourage interdisciplinary studies that integrate insights from microbiology, biogeography, environmental science, and conservation biology.

Longleaf pine forests are economically important habitats that stabilize and enrich the soil and store carbon over long periods. When mixed with oaks, these forests provide an abundance of lichen habitats. The tree canopy lichens promote greater moisture capture and retention and encourage canopy insects. Ground lichens limit some vascular plant germination and growth, promoting a more open and healthy pine community. There is a longstanding mutualistic relationship between longleaf pine habitat and lichens. Longleaf pine habitat has a long history of natural summer burning, which promotes a diverse understory and limits tree densities. Lichen diversity exceeds vascular plant diversity in many mature longleaf pine habitats, yet information on the impacts of prescribed fire on lichen species in these habitats is limited. We assessed lichen diversity and abundance before and after a prescribed ground fire in a longleaf pine/wiregrass habitat near Ocala, Florida. Pre-burn, we found greater lichen abundance and diversity on hardwoods, primarily oak species, than on pines. Post-burn, lichen abundance on hardwoods dropped overall by 28%. Lichen abundance on conifers dropped overall by 94%. Ground lichen species were basically eliminated, with a 99.5% loss. Our study provides insights into retaining lichen diversity after a prescribed burn. Hardwood trees, whether alive or standing dead, help retain lichen biodiversity after burning, whereas conifer trees do not support as many species. Landscapes may need to be actively managed by raking pine needle litter away from ground lichen beds, moistening the ground, or removing some lichen material before the burn and returning it to the site post-fire. Based on these results, we suggest retaining some oaks and conducting burns in a mosaic pattern that retains unburned areas. This will allow for lichens to recover between burns, significantly enhancing biodiversity and the ecological health of these longleaf pine communities. Full article

Epiphytic organisms are characteristic elements of the Andean dry forest, playing a crucial role in ecosystem diversity and functionality, but they are threatened by deforestation-related factors. The diversity of epiphytic lichens and bryophytes was recorded in the Pisaca Reserve, which has an artificial pond locally known as “Laguna Pisaca”, serving as a critical micro-watershed. This pond provides water services to the city of Catacocha, motivating local communities to protect its biodiversity. In each zone (low, middle and high), 10 plots of 5 × 5 m were established, where the presence and coverage of lichens and bryophytes were sampled in 4 trees per plot (120 trees). Richness and diversity (Shannon–Weaver and Simpson indices) were calculated. Generalized linear models (GLM) were used to analyze the effect of the zone on richness and diversity, and multivariate analysis was used to analyze species composition. A total of 90 species were recorded (65 lichens and 25 bryophytes), distributed in three zones: 74 in the high, 67 in the low and 41 in the middle zone. Species richness and composition showed significant variations in relation to the three zones, influenced by forest structure, small altitudinal changes and forests disturbance. The forests of the Pisaca Reserve harbor a great diversity of lichens and epiphytic bryophytes, which serve as refuges for biodiversity in the Andean dry montane forest of South Ecuador. Full article
