At an ecosystem level, stand age has a significant influence on carbon storage (CS). Dragon spruce ( Picea asperata Mast.) situated along the upper reaches of the Bailongjiang River in northwest China were categorized into three age classes (29–32 years, Y 1 ; 34–39 years, Y 2 ; 40–46 years, Y 3 ), and age-related differences in total carbon storage (TCS) of the forest ecosystem were investigated for the first time. Results showed that TCS for the Y 1 , Y 2 , and the Y 3 age groups were 323.64, 240.66 and 174.60 Mg ha −1 , respectively. The average TCS of the three age groups was 255.65 Mg C ha −1 , with above-ground biomass, below-ground biomass, litter, and soil in the top 0.6 m contributing 15.0%, 3.7%, 12.1%, and 69.2%, respectively. CS in soil and TCS of the Y 1 age group both significantly exceeded those of the Y 3 age group ( P < 0.05). Contrary to other recent findings, the present study supports the hypothesis that TCS is likely to decrease as stand age increases. This indicates that natural resource managers should rejuvenate forests by routinely thinning older stands, thereby not only achieving vegetation restoration, but also allowing these stands to create a long-term carbon sink for this important eco-region.

“…However, the much lower δ 15 N values in herbivore bones at the beginning of the Holocene in comparison to later periods, might also be connected with lower total available N (g/m 2 ) in the pioneer stages of soil formation in the glacier forefield, which increases exponentially along the soil developmental gradient (Göransson, Welc, Bünemann, Christl, & Venterink, 2016 Holocene. It seems that despite the change in environmental conditions and growth of total available N (g/m 2 ) in soils (Göransson et al, 2016), δ 15 N values in aurochs did not increase. Aurochs diet in the Neolithic and Late Holocene still had a relatively high fraction of graminoids and forbs (similarly to European bison), but due to lower availability of this plant groups in forest habitats, they had to incorporate some woody material into their diet.…”

Climate warming and human landscape transformation during the Holocene resulted in environmental changes for wild animals. The last remnants of the European Pleistocene megafauna that survived into the Holocene were particularly vulnerable to changes in habitat. To track the response of habitat use and foraging of large herbivores to natural and anthropogenic changes in environmental conditions during the Holocene, we investigated carbon (δ13C) and nitrogen (δ15N) stable isotope composition in bone collagen of moose (Alces alces), European bison (Bison bonasus) and aurochs (Bos primigenius) in Central and Eastern Europe. We found strong variations in isotope compositions in the studied species throughout the Holocene and diverse responses to changing environmental conditions. All three species showed significant changes in their δ13C values reflecting a shift of foraging habitats from more open in the Early and pre‐Neolithic Holocene to more forest during the Neolithic and Late Holocene. This shift was strongest in European bison, suggesting higher plasticity, more limited in moose, and the least in aurochs. Significant increases of δ15N values in European bison and moose are evidence of a diet change towards more grazing, but may also reflect increased nitrogen in soils following deglaciation and global temperature increases. Among the factors explaining the observed isotope variations were time (age of samples), longitude and elevation in European bison, and time, longitude and forest cover in aurochs. None of the analysed factors explained isotope variations in moose. Our results demonstrate the strong influence of natural (forest expansion) and anthropogenic (deforestation and human pressure) changes on the foraging ecology of large herbivores, with forests playing a major role as a refugial habitat since the Neolithic, particularly for European bison and aurochs. We propose that high flexibility in foraging strategy was the key for survival of large herbivores in the changing environmental conditions of the Holocene.

Aims We aimed to assess whether soil salinity changes the microbial community in the rhizosphere of Hibiscus hamabo, and whether these changes in the microbiome feedback on the growth of H. hamabo. Methods To test effects of salinity on the rhizosphere microbiome, we first did a greenhouse experiment in which H. hamabo was grown in pots with a sand-soil mixture at different salt concentrations (0, 15, 40 and 90 mM NaCl). Then in another two experiments, we tested effects of the rhizosphere microbiomes on performance of H. hamabo plants by sowing and growing them in pots with a peat-sand-vermiculite mixture inoculated with either soil or root fragments collected from the different salinity treatments (0, 40 and 90 mM NaCl) of the first experiment and crossed with a salinity treatment (0, 40 and 90 mM NaCl). Results The bacterial rhizosphere community of H. hamabo was less affected by soil salinities than the fungal community was. Germination and biomass of H. hamabo were highest at a salinity of 40 mM NaCl, and higher in the presence than in the absence of microbial inoculums. Moreover, H. hamabo performed best when the microbial inocula came from the same salinity level, particularly at a salinity of 40 mM NaCl. Conclusions Our study provides evidence that salinityinduced changes in rhizosphere microbial communities tend to promote germination and growth of H. hamabo at the respective salinities.
