“…Under the initial condition immediately after defoliation, C concentration was higher in larch litter than broadleaf litter, whereas N concentration was lower for larch, resulting in a larger C:N ratio. A large C:N ratio of fresh litter was reported for Japanese larch (Son et al, 2004). The initial N concentration of 1.06% in larch litter was compatible with that measured at other Japanese larch forests (Osono et al, 2003;Son et al, 2004).…”

The initial N concentration of 1.06% in larch litter was compatible with that measured at other Japanese larch forests (Osono et al, 2003;Son et al, 2004). Moreover, the C and N concentrations and a C:N ratio of broadleaf litter were within the range of those of other broadleaf species (Arunachalam et al, 1998;Wedderburn and Carter, 1999;Read and Lawrence, 2003).…”

We collected leaf litter from a deciduous broadleaf forest and a larch forest in Hokkaido, Japan naturally without using litter traps or litter bags. The litter collection was conducted every month from October 2001 through October 2002 except in the snowy season. We measured the CO 2 production rate of the litter samples through microbial respiration using the chamber method in a laboratory under different temperature and moisture conditions to investigate the seasonal pattern and temperature and moisture responses of CO 2 production at the early stage of litter decomposition. Seasonal variation was found in the CO 2 production rate per unit of litter dry weight (P dw ), or the litter decomposition rate, for both broadleaf and larch litters. Although seasonal patterns differed somewhat according to temperatures and species, P dw reached the minimum in June. The moisture sensitivity of P dw decreased with time and reached the minimum in summer for both broadleaf and larch litters, whereas the seasonal pattern of the temperature sensitivity (Q 10 ) was not clear. The seasonal pattern of P dw was explained by its C: N ratio for broadleaf litter. For larch litter, however, the relationship between P dw and the C:N ratio was complicated because of fresh litterfall supplied gradually before defoliation. The temperature and moisture sensitivities of P dw changed in parallel with the C:N ratio for both broadleaf and larch litters, respectively. These facts suggest the importance of litter chemical quality in the early decomposition process of fresh litter and the validity of the C:N ratio as an index of litter quality.

“…The soil microclimate will also be affected as more radiation reaches the soil, photodegradation being one of the main drivers of litter decomposition and leading to a possible increase in soil temperature and reduced moisture. In turn, these effects could have a notable influence on the decomposition rate of organic matter, with an intensification of decomposition in moist climates (Son et al, 2004;Kunhamu et al, 2009) although the opposite could occur in drier climates (Blanco et al, 2011;LadoMonserrat et al, 2015;Bravo-Oviedo et al, 2017). All these processes can modify soil carbon content and this can be especially significant in the case of the forest floor.…”

Forest management and carbon sequestration in the Mediterranean region: A review

Aim of study: TTo review and acknowledge the value of carbon sequestration by forest management in the Mediterranean area. Material and methods:We review the main effects of forest management by comparing the effects of silvicultural systems (even-aged vs. uneven-aged stands, coppice systems, agroforestry systems), silvicultural options (thinning, rotation period, species composition), afforestation, harvesting, fire impact or effects of shrub layer on carbon sequestration in the Mediterranean area.Main results: We illustrate as forest management can clearly improve forest carbon sequestration amounts. We conclude that forest management is an effective way to maintain and enhance high carbon sequestration rates in order to cope with climate change and provision of ecosystem services. We also think that although much effort has been put into this topic research, there are still certain gaps that must be dealt with to increase our scientific knowledge and in turn transfer this knowledge to forest practitioners in order to achieve sustainable management aimed at mitigating climate change.Research highlights: It is important to underline the importance of forests in the carbon cycle as this role can be enhanced by forest managers through sustainable forest management. The effects of different management options or disturbances can be critical as regards mitigating climate change. Understanding the effects of forest management is even more important in the Mediterranean area, given that the current high climatic variability together with historical human exploitation and disturbance events make this area more vulnerable to the effects of climate change.Additional keywords: global carbon cycle; forest sink; forest mitigation strategies; carbon sequestration potential; climate change mitigation; Mediterranean forests.

“…Improvement of microclimates after thinning could accelerate the rate of litter decomposition in thinned plots (Grady and Hart, 2006;Son et al, 2004), as confirmed by the lower amount of litter in various gaps than in the control (Table 3). During the decomposition, part of C in litter could be transformed to SOC, leading to the increase in SOC in gaps compared with the control (Table 3).…”
