Special Issue Information

Dear Colleagues,

An understanding of regeneration is of paramount importance to examine the build-up of future forest structure and composition. The processes involved in sexual and asexual tree regeneration can be influenced by many factors, such as variations in seed dispersal intervals, seed quality, wind direction and speed, slope gradients and aspects, and soil moisture availability. Intra- and interspecific competition for water, nutrients, light, and space are also important factors in the regeneration and growth of species. Moreover, regeneration dynamics are a heterogenic aspect of forests, and environmental conditions are significantly affecting the survivorship rate within the seedling bank as well as their species composition under similar canopy composition. In turn, natural regeneration can also be affected by human disturbances (deforestation, soil degradation, grazing, fire), changing the species composition of the forest stands and determining species diversity at the canopy.

This Special Issue will focus on the impact of disturbances (natural and/or anthropogenic) on regeneration and how they can be considered intrinsic processes of forest dynamics. A relevant question regarding species conservation is how the dependence of many of these species has been affected by changes in the rate or intensity of disturbances due to human activity.

The analysis of grazing, fire, or introduced species on regeneration can reveal important aspects of the sustainability of forest structure and canopy diversity.

Manuscripts on any aspect of forest species regeneration are welcome, though studies that have analyzed relevant disturbances and their relationship with regeneration are of particular interest. These analyses should reveal important aspect of interest for forests restoration and conservation management.

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. Ecologies is an international peer-reviewed open access quarterly 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 1000 CHF (Swiss Francs).

Exotic afforestation can provide suitable conditions for native shade-tolerant species restoration without threatening native forests. This study analyzes the impact of different thinning intensities of the canopy of an exotic Pinus radiata stand on the asexual regeneration response of Ilex canariensis, a native laurel forest species in the Canary Islands, Spain. The results provide useful indications for how to manage P. radiata stands to promote recovery of native plant communities. For different stand treatments were selected: stand clear cut, low intensity thinning (10–15%), high intensity thinning (25%), and a control. The stand clear cut management revealed Ilex canariensis individuals with a higher number of sprouts and more leaf cover; however, the height of these sprouts two years after the cut did not reach the values of individuals prior to this management. Consequently, the vitality index following clear cut management is significantly lower with respect to the other treatments. Thinning management is shown not to be so useful to promote the growth and vitality of Ilex canariensis individuals. The results suggest that thinning over 50% could be more appropriate in the case of Pinus radiata, allowing resprouting of Ilex canariensis in the understory and improvement in the vitality index.
