“…These results could be explained by the similar slow decomposition rates and litter mass accumulation of C. ramosissima in control and flowered plots. Decomposition of bamboo litter was slower on average than rates of mass loss in other subtropical forests (Deka and Mishra, 1982;Singh and Singh, 1999), and substantially reduced compared to the subdominant tree species such as S. bonplandii. Our results were similar to the findings of Liu et al (2000) in a subtropical mountain forest in China for the bamboo Sinarundinaria nitida, which requires more than 6 years to lose 95% of their initial mass, and consistent with another study of Chusquea bamboo flowering which demonstrated significantly slower decomposition of bamboo litter, particularly stem tissue (Austin and Marchesini, 2011).…”

“…Although a single study in a subtropical forest showed no site‐specific effects of a sporadic bamboo flowering event on litter decomposition (Montti et al. 2011), litter quality of bamboo and agricultural activity have been shown to be factors affecting decomposition in ecosystems where bamboo species are an important component of the vegetation (Deka & Mischra 1982; Tripathi & Singh 1992b; Arunachalam, Upadhyaya & Arunachalam 2005, Fujimaki, Takeda & Wiwatiwitaya 2008). A study in a tropical savannah showed similar trends, with leaf and sheath litter decomposing substantially faster than stem tissue (Tripathi & Singh 1992a).…”

Summary1. The massive synchronized flowering and subsequent mortality of understorey bamboo species occur in infrequent and unpredictable intervals in temperate and subtropical forests around the world. Because of the sporadic occurrence of these flowering episodes and the long intervals between events, very little is known about their consequences on biogeochemical cycling in natural ecosystems. 2. In 2001, a synchronized flowering and dieback of the native bamboo, Chusquea culeou E. Desv., occurred, covering more than 200 000 ha in the north-west region of Patagonia, Argentina. We explored the impacts of this gregarious flowering event on litter decomposition and nitrogen turnover in an old-growth southern beech forest for 3 years after the flowering event.3. Bamboo litter decomposed significantly slower than overstorey tree litter, and decomposition in flowered patches overall was significantly reduced compared to remnant live understorey patches. In addition, soil mineral nitrogen was reduced in flowered patches, and nitrogen transformations were altered, most notably in the third year after the flowering event.4. This infrequent phenomenon of gregarious flowering could have consequences for carbon and nutrient cycling, as low-quality standing dead biomass is gradually incorporated into soil organic matter pools. This study demonstrates that large biotically mediated perturbations of understorey vegetation can impact biogeochemical cycles in temperate forest ecosystems by reducing carbon turnover and altering nitrogen availability and transformations, even in the absence of physical disturbance.

“…Fungal succession during litter decomposition has been observed on several litters of forest tree species (Hudson 1968; Swift 1976). In earlier works, successional changes in fungal populations were investigated by the dilution plating method (Saito 1956; Ishii 1968; Deka & Mishra 1982; Kuter 1986; Singh et al 1990). Most fungi isolated by this method are, however, derived from dormant spores attached to the litter surface (Warcup 1955; Christensen 1969).…”

Decomposition processes of beech leaf litter were studied over a 3‐year period in a cool temperate deciduous forest in Japan. Organic chemical and nutrient dynamics, fungal biomass and succession were followed on upper (Moder) and lower (Mull) of a forest slope. Litter decomposition rates were similar between the sites. Nutrient dynamics of the decomposing litter was categorized into two types: weight changes in nitrogen and phosphorus showed two phases, the immobilization (0–21 months) and the mobilization phase (21–35 months), while those in potassium, calcium and magnesium showed only the mobilization phase. The rate of loss of organic chemical constituents was lignin < holocellulose < soluble carbohydrate < polyphenol in order. The changes in lignocellulose index (LCI), the ratio of holocellulose in lignin and holocellulose, were significantly correlated to the changes in nitrogen and phosphorus concentrations during the decomposition. During the immobilization phase, increase in total fungal biomass contributed to the immobilization of nitrogen and phosphorus. The percentage of clamp‐bearing fungal biomass (biomass of the Basidiomycota) to total fungal biomass increased as the decomposition proceeded and was significantly correlated to LCI. Two species in the xylariaceous Ascomycota were dominantly isolated by the surface sterilization method from decomposing litter collected in the 11th month. The organic chemical, nitrogen and phosphorus dynamics during the decomposition were suggested to be related to the ingrowth, substrate utilization and succession of the Xylariaceae and the Basidiomycota. Twenty‐one species in the other Ascomycota and the Zygomycota isolated by the washing method were classified into three groups based on their occurrence patterns: primary saprophytes, litter inhabitants and secondary sugar fungi. These species showed different responses to LCI and soluble carbohydrate concentration of the litter between the groups.
