“…1). It is plausible that grazing-induced declines in moss depth may cascade into moss-mediated soil water availability, and could even amplify the differences that exist among drier and moister microclimatic habitats in (oligotrophic) boreal forests (Haughian and Burton 2018).…”

“…Mosses together with lichens and ericaceous dwarf shrubs form the boreal forest (taiga) floor vegetation, which is partly controlled by wildfires and consequent succession where lichens dominate early and mosses and dwarf shrubs later in the successional sequence (Nilsson and Wardle 2005). However, at smaller scales, these plants alternate depending on microclimate: in comparison to mosses and dwarf shrubs, lichens are more abundant in drier microclimatic habitats sustained by soil properties and forest canopy structure (Haughian and Burton 2018;Vitt et al 2019). Furthermore, mosses and lichens respond to ungulate grazers, such as reindeer (Rangifer tarandus L. caribou in North America), whose decimating impacts on lichens are well established across taiga and tundra (Bernes et al 2015;Köster et al 2015;Horstkotte and Moen 2019;Uboni et al 2019).…”

Plant and soil nitrogen in oligotrophic boreal forest habitats with varying moss depths: does exclusion of large grazers matter?

The boreal forest consists of drier sunlit and moister-shaded habitats with varying moss abundance. Mosses control vascular plant–soil interactions, yet they all can also be altered by grazers. We determined how 2 decades of reindeer (Rangifer tarandus) exclusion affect feather moss (Pleurozium schreberi) depth, and the accompanying soil N dynamics (total and dissolvable inorganic N, δ15N), plant foliar N, and stable isotopes (δ15N, δ13C) in two contrasting habitats of an oligotrophic Scots pine forest. The study species were pine seedling (Pinus sylvestris L.), bilberry (Vaccinium myrtillus L.), lingonberry (V. vitis-idaea L.), and feather moss. Moss carpet was deeper in shaded than sunlit habitats and increased with grazer exclusion. Humus N content increased in the shade as did humus δ15N, which also increased due to exclusion in the sunlit habitats. Exclusion increased inorganic N concentration in the mineral soil. These soil responses were correlated with moss depth. Foliar chemistry varied due to habitat depending on species identity. Pine seedlings showed higher foliar N content and lower foliar δ15N in the shaded than in the sunlit habitats, while bilberry had both higher foliar N and δ15N in the shade. Thus, foliar δ15N values of co-existing species diverged in the shade indicating enhanced N partitioning. We conclude that despite strong grazing-induced shifts in mosses and subtler shifts in soil N, the N dynamics of vascular vegetation remain unchanged. These indicate that plant–soil interactions are resistant to shifts in grazing intensity, a pattern that appears to be common across boreal oligotrophic forests.

“…The contribution of each layer in the broadleaf forests to the total carbon storage of the study area is greater than that of the corresponding layer in the mixed forests. The different types of forest exhibit a stratification phenomenon, and large differences exist in the structure and function, resulting in vertical hierarchies and eventually leading to a huge difference in the carbon storage capacity [17,46].…”

To provide a comprehensive understanding of the spatial distribution of forest carbon reserves, this study explores carbon storage and its spatial pattern in the horizontal and vertical directions on a provincial scale using HJ-CCD remote sensing imagery. Results show that carbon storage in the forests of Hubei Province was 784.46 Tg. In the horizontal direction, Enshi Prefecture contributed the most, with a contribution rate of 22.01%, followed by Yichang (18.74%), Shiyan (15.21%), and Xiangfan (10.61%). Coniferous forests contributed the most to the total carbon reserves of the forests, with a contribution rate of 71.34%, followed by broadleaf forests (25.36%), and mixed forests (3.30%). In the vertical direction, the environmental difference in the vertical direction of the forest ecosystem led to the obvious stratification of carbon storage in the vertical direction, that is: soil layer > tree canopy layer > shrub layer > litter layer. The soil layer had the largest carbon storage, contributing 76.63%, followed by the tree canopy layer (19.05%), shrub layer (2.39%), and litter layer (1.93%). The different contributing layers of coniferous, broadleaf, and mixed forests to carbon storage followed the same order: soil layer > tree canopy layer > shrub layer > litter layer.

Lichens are organisms capable of interacting with the environment, playing an important role in the modification of their substrate. In coastal areas of northeastern Brazil with sandy soils, as an extension of Atlantic rainforest, or in an interface with semi-arid Caatinga biome and high mountain humid forests, named brejos, lichens of the family Cladoniaceae are found forming pillows on these soils. They interact with their substrate, influencing the chemical composition and biota. In this study, we summarize data about the interaction of these lichens with Quartzarenic Neosols, which occurs in this phytophysiognomy named tabuleiros or cerrados.
