Special Issue Information

Dear Colleagues,

The adaptation of forest lichen and moss systems to invasive species and disturbances involves a complex interplay of ecological dynamics, resilience, and evolutionary adjustments. Lichens and mosses, which are key components of forest ecosystems, often serve as indicators of environmental health due to their sensitivity to changes in their habitats. The main factors influencing such ecological dynamics are as follows:
Competition: Invasive species often compete with native lichens and mosses for resources such as light, space, and nutrients. This can lead to reduced growth and survival rates of native species.

Altered Habitats: Invasive species can modify habitats by changing the microclimate, soil chemistry, or physical structure of the environment. For instance, invasive plant species may alter the light availability or soil nutrients, negatively impacting lichen and moss communities.

Disturbances: Events such as wildfires, storms, or human activities disrupt ecosystems, affecting lichen and moss populations. These disturbances can be beneficial for some species by creating new colonization opportunities but detrimental for others by destroying established communities.

Possibilities of Resilience and Recovery: Some bryophyte and lichen species exhibit remarkable resilience to disturbances and invasive species by employing survival strategies like dormancy or rapid reproduction. Resilient species tend to recover quickly and can reestablish themselves, maintaining their role in the ecosystem.

After a disturbance, forest ecosystems often undergo a process of secondary succession, where lichens and mosses are typically among the first organisms to colonize the new or altered environment. Their presence helps stabilize the soil and provides habitats for other species. The adaptation of forest lichen and bryophyte ecosystems to invasive species and disturbances reflects their inherent resilience and the dynamic nature of ecological systems. Effective management and conservation strategies form the basis of the conservation of these valuable communities.

Potential topics include but are not limited to the following:

  • Stress effects on lichens and mosses;
  • Adaptation and resilience of lichen and moss systems;
  • Monitoring;
  • Management implications.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Forests is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Forest litter can decompose faster at home sites than at guest sites (home-field advantage, HFA), yet few studies have focused on the response of the HFA of native plant decomposition to the presence of invasive plants. We loaded the dry leaves of native Neosinocalamus affinis (decomposition resistant) and Ficus virens (more easily decomposable) leaves into litterbags with and without invasive Alternanthera philoxeroides, and incubated these litterbags at N. affinis and F. virens sites at the edge of the forest. The results showed that positive HFA effects with litter mass loss were at least 1.32% faster at home sites than at guest sites. The addition of A. philoxeroides reduced the mean HFA of N. affinis litter and increased that of F. virens litter. The HFA index without A. philoxeroides was significantly higher than that with A. philoxeroides. Soil faunal abundance colonized at home sites was always higher than that colonized at guest sites. Compared with the F. virens site, the abundance of Collembola, Arachnida, Formicidae and Lepismatidae at the N. affinis site was significantly higher compared to the F. virens site, while the abundance of Isopoda, Oligochaeta, Nematoda and Dermaptera was significantly lower. Our results indicate that invasive plants may regulate HFA effects by promoting the decomposition of native plants and increasing fauna abundance. Particularly, soil fauna groups play a very important role in this process. Our findings help us to re-understand the role of invasive plants in material cycling and energy flow in the context of achieving carbon neutrality goals. Full article
