ABSTRACT Litter decomposition is critical for maintaining productivity and nutrient cycling in forest ecosystems. Large herbivores play an essential role determining the processes of cycling. Asian temperate forests are becoming degraded fragmented by widespread intensification anthropogenic activities, including excessive livestock grazing. However, effects grazing wild ungulates on litter remain less explored. In this study, we used a litterbag experiment to investigate addition cattle ( Bos taurus ) sika deer Cervus nippon feces decomposition. The study was conducted Northeast China from July 2022 October 2023. We found that significantly reduced decomposition, but greatly increased presence excrement accelerated release C after 1 year Compared with results control group (no feces), 37.45% 22.69%, respectively.

Abstract Ecological stoichiometry is an important approach to understand plant nutrient cycling and balance in the forest ecosystem. However, understanding of stoichiometric patterns through leaf‐litter‐soil system Mongolian pine among different stand origins still scarce. Therefore, reveal variations carbon (C), nitrogen (N), phosphorus (P) homeostasis origins, we measured C, N, P concentrations leaves, litter, soil, analyzed resorption efficiencies leaves differently aged plantations natural forests from semi‐arid dry sub‐humid regions. The results showed that (1) origin had a significant effect on C–N–P stoichiometry, also significantly affected leaf N reabsorption efficiencies. Leaf N/P ratios indicated was co‐limited by NF, HB HQ, mainly limited MU. (2) With increasing age, C initially increased then decreased, were gradually increased. Overall, age concentrations, C/N C/P system. (3) elements between strong coupling relationship, element litter‐soil relationship. In addition, exhibited greater than forests, alone, which may be utilization strategy for alleviate or limitation. (4) Environmental factors have influence system, most soil properties meteorological being water content precipitation, respectively. These will essential provide guidance plantation restoration management desert

The ecological stoichiometric characterization of plant and soil elements is essential for understanding the biogeochemical cycles ecosystems. Based on three forest ages Pinus taiwanensis Hayata (P. taiwanensis) plantations in Gujingyuan National Nature Reserve (i.e., young (16 years), middle-aged (32 mature forests (50 years)), we conducted a field experiment to analyzed C, N, P stoichiometry relationships between needles, litter, soil, micro-organisms P. plantations. We intended elucidate nutritional characteristics stability mechanisms artificial ecosystem. results showed that C contents live leaf plantation were 504.17–547.05, 527.25–548.84, 23.40–35.85, 0.33–0.54 g/kg, respectively; respective N 11.02–13.35, 10.71–11.76, 1.42–2.56, 0.08–0.12 g/kg; 0.82–0.91, 0.60–0.74, 0.19–0.36, 0.03–0.06 g/kg. Forest age significantly influenced both as well (p < 0.05). Furthermore, although litter N:P content was comparable ratios C:N C:P notably higher compared those needles. Soil highest while microbial continuously decreased. Stoichiometric analyses our findings suggest stand can influence divergent changes element cycling among plants, micro-organisms. presented aid further nutrient utilization strategies regulatory systems.

In the context of global climate change, atmospheric nitrogen deposition is increasing, and precipitation patterns are becoming more variable. This study examines impact these changes on (N) allocation mechanisms in semi-arid region tree species using one-year-old Mongolian pine (Pinus sylvestris var. mongolica) seedlings. The seedlings were planted soil collected from Daqinggou Sandy Ecological Experiment Station (42°54′ N, 122°25′ E). Three moisture treatments applied (WC (normal moisture, approximately 65% ± 2.5% field capacity), WI (30% increased moisture), WD decreased moisture)), as well three (NC (no nitrogen), NL (5 g·m−2·y−1 NH (10 nitrogen)). sprayed with a 15N-labeled CH4N2O solution (46% 15N abundance 10.14%) pot trial, samples taken August October to measure N content seedling organs soil. Parameters such Ndff (%) (the percentage derived fertilizer), organs, absorption distribution ratio calculated. results showed that followed trend leaves > stems roots. Under treatments, ratios leaves, stems, roots 63.63–71.42%, 14.89–24.14%, 12.23–14.88% under low nitrogen, 62.63–77.83%, 13.35–22.90%, 7.31–19.18% high nitrogen. Significant correlations found among coefficients ranging 0.97 1.00. main effects their interaction, significantly impacted organs. Changes levels affected capacity pine. Increased enhanced all leading 62.63–71.42% being allocated maintaining an appropriate proportion stems. Nitrogen altered strategy different conditions reduced greater was captured by increase 4.98–5.77% compared control group, thereby mitigating adverse water deficiency. active accumulated limiting elements, 2.03–8.07% group. To achieve optimal strategy, moderate combined uptake provides scientific evidence for ecological restoration, wind erosion control, agricultural forestry management regions change.
