“…In particular, a bird exclusion experiment previously conducted in three of our six gradients showed similar effects of bird predation on insect herbivory in alpine tundra and in lowland forests (Zverev et al, 2020). Moreover, the density of invertebrate predators in the Khibiny Mountains was higher in the alpine tundra than in the forests (Zenkova et al, 2011). Therefore, we conclude that the increase in herbivory with elevation in our study region is unlikely shaped by the elevational changes in top‐down factors.…”

Current theory holds that the intensity of biotic interactions decreases with increases in latitude and elevation; however, empirical data demonstrate great variation in the direction, strength, and shape of elevational changes in herbivory. The latitudinal position of mountains may be one important source of this variation, but the acute shortage of data from polar mountains hampers exploration of latitude effects on elevational changes in herbivory. Here, we reduce this knowledge gap by exploring six elevation gradients located in three Arctic mountain ranges to test the prediction that a decrease in herbivory occurs with increasing elevation from forest to alpine tundra. Across the 10 most abundant evergreen and deciduous woody plant species, relative losses of foliage to insect herbivores were 2.2‐fold greater at the highest elevations (alpine tundra) than in mid‐elevation birch woodlands or low‐elevation coniferous forests. Plant quality for herbivores (quantified by specific leaf area) significantly decreased with elevation across all studied species, indicating that bottom‐up factors were unlikely to shape the observed pattern in herbivory. An experiment with open‐top chambers established at different elevations showed that even a slight increase in ambient temperature enhances herbivory in Arctic mountains. Therefore, we suggest that the discovered increase in herbivory with elevation is explained by higher temperatures at the soil surface in open habitats above the tree line compared with forests at lower elevations. This explanation is supported by the significant difference in elevational changes in herbivory between low and tall plants: herbivory on low shrubs increased fourfold from forest to alpine sites, while herbivory on trees and tall shrubs did not change with elevation. We suggest that an increase in herbivory with an increase in elevation is typical for high‐latitude mountains, where inverse temperature gradients, especially at the soil surface, are common. Verification of this hypothesis requires further studies of elevational patterns in herbivory at high latitudes.

“…Small-size invertebrates exhibiting a short cycle of development and usually concentrated in the litter layers are exposed to abrupt changes in temperature and moisture (Briones et al, 1997;Zenkova et al, 2011). This leads to important seasonal variations of soil communities, both in species composition and abundance, as well as to vertical stratification when cold/hot or waterlogged/dry spells create unfavourable conditions to their activities at the surface (Fig.…”

“…4). For example, in a study of soil invertebrate communities along an altitudinal gradient Zenkova et al (2011) found that soils become impoverished in autumn across all altitudinal zones and that certain groups of macrofauna (earthworms, gastropods, and some insects) disappeared completely from the litter layer in midSeptember. Similarly, Solida et al (2015) found that moister, more continental and relatively undisturbed woodlands with a closed canopy and high humus quality sustained a more complex microarthropod community, whereas more disturbed and xeric Mediterranean woodlands showed lower values of all investigated biodiversity parameters due to water limitation.…”

“…fly larvae, enchytraeids, epigeic earthworms). This leads to seasonal variation, both in species composition and abundance, as well as to downward migration when cold or dry seasons create unfavourable conditions for the animal's surface activities (Briones et al, 1997;Lindberg and Bengtsson, 2005;Salmon et al, 2006;Makkonen et al, 2011;Petersen, 2011;Zenkova et al, 2011;Solida et al, 2015), but also changes in their feeding strategies, with concomitant implications for humus formation.…”

“…We found 88 species of Aranei, 50 species of Staphylinidae, 4 species of Lumbricidae, 10 species of Mollusca, 11 species of Carabidae and others in the communities of the Vudjavrchorr mountain (Table 3). Also some species are known from literature [Zenkova et al, 2011]. Thus macrofauna of this area numbers over 170 species; the most part of them is wide-spread boreal.…”

Clear soil macrofauna dynamics in forest-tundra ecotones of the Khibiny mountains havent been found over 23 years period. But abundance of macrofauna in two forest types significantly increased in 20092010 when compared to 1986. There are three types of macrofauna complexes: forest with higher earthworms densities, tundric with macrofauna of low diversity and high abundance, and ecotone. Increasing densities and numbers of all macrofauna and dominant taxa werent recorded in forest-tundra ecotone. Green moss covering determines the affinity of macrofauna in both spruce forest and tundra. For north foresttundra ecotone the distribution of earthworms depends on winter minimal temperature of soil. ÐÅÇÞÌÅ.
