“…In general, soils developed under conifers have a more acidic pH than under broad-leaved species (Vittori Antisari et al 2011). In this study, an opposite trend was identified that could be explained by the large amounts of humic and fulvic acid deposits recorded in Apennine beech forests (Danise et al 2018), a consequence of decomposition of beech litter that has high concentrations of cellulose and lignin and comparatively high levels of N (Innangi et al 2015b(Innangi et al , 2018. Litter that is high in both lignin and N has a slow decay rate and can lead to the development of thick humified layers in the soil (Berg et al 1995;Hedde et al 2008;Danise et al 2020).…”

“…In line with our results, in more than 10,000 soil profiles, Jobbágy and Jackson (2000) found a higher concentration of N and other nutrients within the upper 20-cm layer compared with deeper layers. Variations in carbon and nitrogen, and in general, in organic matter levels with depth may also suggest rapid degradation and/or a slow vertical redistribution by mesofauna (De Marco et al 2016;Fioretto et al 2018;Innangi et al 2018;Menta et al 2018).…”

“…Given two matrixes with different variables but the same observations, 2B-PLS builds pairs of variables as linear combinations within each of the two sets in order to explain as much covariance as from the original sets (Rohlf and Corti 2000). This statistical approach has been used successfully on several ecological studies (Innangi et al 2017a(Innangi et al , 2018(Innangi et al , 2019(Innangi et al , 2020Battipaglia et al 2020). Statistical analyses were performed using software R version 3.6.0 (R Core Team 2019) and packages 'vegan' (Oksanen et al 2013), 'ggplot2′ (Wickham 2016) and 'plsdepot' (Sanchez 2012).…”

Both climate and land-use changes, including the introduction and spread of allochthonous species, are forecast to affect forest ecosystems. Accordingly, forests will be affected in terms of species composition as well as their soil chemical and biological characteristics. The possible changes in both tree cover and soil system might impact the amount of carbon that is stored in living plants and dead biomass and within the soil itself. Additionally, such alterations can have a strong impact on the detrital food web that is linked to litter decomposition. Although there are studies on the influence of plant diversity on soil physical and chemical characteristics, the effects on soil biological activity and carbon storage processes remain largely unknown. The aim of this study was to investigate and compare chemical and biological variables in covariation with plant communities in an autochthonous beech forest (Fagus sylvatica L.) and a black pine plantation (Pinus nigra J.F. Arnold subsp. nigra). Our results confirmed that the two communities were considerably different, with the old-growth beech community having a lower number of plant species and the pine community was in development as a consequence of anthropogenic activities. These aspects of the two communities were also reflected in the soil, with the beech soil having higher nitrogen levels and a more specialized microbial community compared to the pine soil, with most extracellular enzymes (such as peroxidase and chitinase) showing lower activity in the pine soil.

“…The collembola group represented 60% of the individuals in NT1, 50% in EUC and 40% in FA, this dominance presented by the collembola group in the burlap is well documented (Menta et al, 2014;Innangi et al, 2018). However, the frequency of these individuals is positive, as these soil microarthropods have significant influence on soil microbial ecology, nutrient cycling, and soil fertility by feeding on soil microorganisms and dead organic matter (Oliveira Filho & Baretta, 2016).…”

The soil fauna is one of the bioindicators of soil quality that has greater sensitivity, being easily altered by changes that occur in natural and agricultural ecosystems. The objective of this work was to evaluate the density and diversity of the soil macrofauna and the functional groups of the epigeal macrofauna that are most representative in no-tillage, pasture, eucalyptus cultivation and native savanna systems in Uruçuí, Piauí, Brazil. Five soil management systems were used: pasture (PAS); no tillage soybean in corn straw (NT1); no tillage of corn under straw of mombaça grass (NT2); eucalyptus (EUC), in addition to a savanna area used as a reference (FA). Fauna collection was performed using pitfall traps containing 4% formaldehyde. The fauna was evaluated by the number of individuals per trap per day, wealth, average wealth, Shannon's diversity index and Pielou's uniformity index. The data was subjected to analysis of variance, and when significant, was subjected to the Friedman test. The pasture system had the least impact on edaphic fauna when compared to native savanna forest and when compared to management systems and the collembola, orthoptera and diptera groups were the most abundant in the studied management systems.

“…Generally, the more the litter storage, the thicker the litter layer and the higher the decomposition degree, and the better its hydrological regulation ability. Scholars have carried out a large number of studies on the ecological functions of forest litter in China and in other countries, mainly focusing on the litter storage (Ge et (Innangi et al 2018). With the deepening of research on litter ecology, an increasing number of experts and scholars in the elds of ecology, forestry, geochemistry, and environmental science have focused on litter function (Xiao and Guan, 2018;Quadros et al 2019;Olsson et al 2019;Faust et al2019).…”

Taking the litter layer of three typical plant communities (broad-leaved forest, coniferous forest, and shrubs) as the research object, this study analyzed the hydrological function characteristics of the litter layers of different typical plant communities using the indoor immersion method in order to reveal the effects of the traits of the litter layer on the hydrological functions of typical plant communities in the core area. The results showed that: (1) the litter reserve change trend decreased in order as follows: broad-leaved forest (13.31 ± 1.54 t/hm2) > shrubs (12.62 ± 2.34 t/hm2) > coniferous forest (11.36 ± 1.43 t/hm2). The coniferous forest and shrub litter reserves increased significantly with the increase of decomposition degree (F = 19.36, P < 0.01; and F = 9.19, P < 0.01, respectively), while the broad-leaved forest litter reserves decreased first and then increased significantly with the increase of decomposition degree (F = 25.70, P < 0.01); (2) the litter natural moisture content change trends were as follows: shrubs (34.09 ± 4.31 t/hm2) > broad-leaved forest (31.32 ± 1.76 t/hm2) > coniferous forest (29.48 ± 7.02 t/hm2). The change trends of the maximum water-holding capacity, maximum interception amount, maximum interception rate, effective interception amount, and effective interception rate were in descending order as follows: broad-leaved forest > shrubs > coniferous forest. The maximum water-holding capacity, maximum interception amount, and effective interception amount of litter rose with the increase of decomposition degree. The broad-leaved forest community litter layer had the strongest rainfall interception function and the best hydrological service functions. The interception function was stronger with the increase of the decomposition degree of the litter layer; (3) the water-holding and water-releasing capacity variation of the litter layers manifested as reversed “J” features for the three typical plant communities. The water-holding capacity of different plant community litter layers (Qct) was significantly positively correlated with time (t) (P < 0.01), and the equation was Qct = b + alnt, whereas the water-releasing capacity of different plant community litter layers (Qst) was significantly positively correlated with time (t) (P < 0.01), and the equation was Qst = a t b; and (4) the water absorption and release rates of the litter layers had four periods. The water absorption rate (v) was significantly negatively correlated with time (t) (P < 0.01), and the equation was v = a t− b, while the water release rate was the same. The water absorption and release rates differed by one order of magnitude in the first 5 min, exhibiting the greatest regulation and storage function, while the rate differed by only 2.1–4.5 times during the last three periods. This shows that the litter layer has the strongest rainfall regulation and storage function for only a short period of time before declining.
