Special Issue Information

Dear Colleagues,

Forests are essential for life on earth and for human well-being. They provide habitat for approximately 80% of the world’s terrestrial biodiversity, protect watersheds, supply oxygen and provide many material goods. Many of these ecosystem services are delivered or enhanced by plant–animal interactions, which influence the ecological stability of ecosystems, energy fluxes, nutrient cycling, species composition, species distribution, etc. Our knowledge of the importance of plant–animal interactions to forest ecosystem functioning is very low, especially when taking into account the very wide range of existing plant–animal co-adaptations occurring on the structural, molecular and physiological levels. The range of potential direct and indirect plant–animal interactions is very wide and includes all types of relationships between any animal and any plant, from antagonistic via mutualistic to commensal.

This Special Issue of Forests is devoted to the ecology of plant–animal interactions in forest ecosystems. Submitted articles may focus on any interaction involving animal and plant partners: from animal herbivory and plant carnivory, plant pollination and seed dispersal to indirect enhancement of tree recruitment by a ‘landscape of fear’. Thus, any study increasing our understanding of the coevolutionary relationships between plants and animals and their importance to forest functioning are welcomed by the editors.

For Central European herbs, ants are one common dispersal vector acting at relatively small spatial scales. Though extensively studied concerning the different benefits to plants, specific dispersal patterns mediated by ants have been reportedly very sparsely and without any validation. Thus, we studied the seed dispersal pattern of a set of myrmecochorous plant species in a novel mesocosm experiment. We examined the seed dispersal distances of four forest herbs (Hollow Root–Corydalis cava (L.) Schweigg. & Körte, Alpine Squill–Scilla bifolia L., and Common Dog-violet–Viola riviniana Rchb. and the annual Ivy-leaved Speedwell–Veronica hederifolia L.) by the red ant Myrmica ruginodis Nylander in 8.25 m² large plots under natural conditions with and without ants. In the presence of Myrmica ants, the bulb geophytes C. cava and S. bifolia showed a significantly higher fraction of dispersed seedlings and a maximum dispersal distance of 322 cm. Estimated by nearest neighbor analyses, distances between single C. cava seedlings were significantly higher in ant plots than in exclosures without ants. The annual species Veronica hederifolia showed a few dispersed seedlings in ant plots only, while the diplochorous hemicryptophyte Viola riviniana germinated in a widely scattered manner with distances up to 241 cm due to ballochorous dispersal in both ant and exclosure plots, but with a maximum of 324 cm only by means of ants. Our results indicate the escape from the mother plant and dispersal for distance as an important benefit for myrmecochorous species, potentially accompanied by benefits through reduced competition.

The study examines the influence of Polish primitive horse grazing on vegetation in deciduous and coniferous old forest stands in north-east Poland. It was conducted in both forest sites in two complexes located in: (i) the fenced area of the Popielno Research Station of the Polish Academy of Sciences, with free-living Polish pony [Polish primitive horse (Equus ferus caballus Linnaeus, 1758)] in 130-year-old stands, and (ii) in the open 116-year-old managed (harvested) Maskulińskie Forest District, without horses. In both areas the stands are inhabited by free-living red and roe deer. The impact of forest animals on ground cover layer as well as on understory shrub layer and undergrowth was compared. Very significant differences in the structure of the understory and undergrowth (above 0.5 m) layer vegetation communities between both areas and type of stands were found. The results suggest that the presence of the Polish horse substantially changed the species composition and increased the species diversity of the ground layer and shrub layer both in the coniferous forest and deciduous forest habitats. The height of the shrub layer trees was lower by 30% in the area with the Polish horse. The level of biodiversity of forest plants was dependent on the presence of the Polish horse, which in the past was one of the natural inhabitants of forests in the area of research. Full article

Research Highlights: We demonstrated that the resistance mechanisms of plants could be used to combat damage caused by pests in forestry plantations. Background and Objectives: Poplar is the main tree species used in plantations in northern China, with Micromelalopha sieversi (Staudinger) representing a major pest species causing defoliation. Here, we investigated whether two poplar clones could resist this pest species and the physiological mechanisms involved. Materials and Methods: Two clones of Populus from section Aigeiros were used, with ‘108’ (P. × euramericana ‘Guariento’) being more attractive to M. sieversi than ‘111’ (P. × euramericana ‘Bellotto’). Three treatments were set up (oviposited plants, neighboring plants, and control plants) to determine whether resistance was induced in plants neighboring oviposited plants. Results: Significantly fewer eggs were oviposited on neighboring plants compared to control plants for both clones, with more eggs being laid on oviposited and control plants of ‘108’ compared to ‘111’. β-Pinene was detected in oviposited and neighboring plants, but not control plants for either clone. Significantly higher concentrations of 3-carene was present in oviposited and neighboring plants of ‘108’ and ‘111’ compared to control plants at 24, 48, and 72 h after oviposition. Males, females, and mated females primarily responded to electroantennogram (EAG), methyl palmitate and 2-ethylhexyl acrylate at 50 ng/μL, and to 3-carene and β-pinene at 5 ng/μL, and to styrene at 10 ng/μL in EAG assays. When using these concentrations on plant leaves, 3-carene, β-pinene, and styrene significantly reduced the number of eggs laid on ‘108’, while 3-carene and β-pinene were effective for ‘111’. Conclusions: Plants neighboring oviposited plants exhibited defense responses; 3-carene and β-pinene were used to transmit chemical signals (volatile cues) from oviposited plants to neighboring plants; which induced neighboring plants released volatiles as a defense mechanism to prevent egg laying.
