“…The soils were formed from different parent materials, from sandstone to diabase, which resulted in oxisols with medium (red-yellow oxisol) to high fertility (red oxisol). All forest remnants contained considerable litter stocks (8.1-11.8 Mg ha -1 ), as typically observed in other tropical forests (Ostertag et al 2008, Tang et al 2010. The predominant land use around the forest remnants is agriculture in Holambra and Americana, industry and agriculture in Paulínia, while a mix of urban and agricultural areas is found in Campinas and Jaguariúna (Tab.…”

© iForest -Biogeosciences and Forestry IntroductionThe Brazilian Atlantic biome is recognized as one of the hotspots for the conservation of biodiversity (Forzza et al. 2012), though it is severely affected by diverse human interferences, particularly in the State of São Paulo, southeastern Brazil (Domingos et al. 2003). The semideciduous Atlantic Forest is highly fragmented in central-eastern São Paulo because of the expansion of agriculture and urban and industrial growth (Nalon et al. 2008). Besides the reduction of forest cover, human activities bring about a variety of pollutants from combustion of fuels, waste disposal, long-term sewage sludge and fertilizer application and other sources, which may be toxic to the plant community and modify the chemical status of soil, depending on its original chemical and physical conditions (Nriagu 1990, Sharpley 1995, Schaaf et al. 2004, Pouyat et al. 2008, Lucas et al. 2011. Soil nutrients are among the main factors that regulate plant growth and play an important role in the sustainable use of soils; however, their excess due to pollution from human sources may damage the soils and affect the soil-plant relationships. Air pollution may also disrupt other nutrient cycling processes in natural ecosystems, such as the decomposition of litter (Cotrufo et al. 1995).Most anthropogenic pollutants deposited in forest ecosystems accumulate in the soil surface layers (Ruan et al. 2008), where pollutants are typically immobilized for long periods (Hawkins et al. 1995, Verstraeten et al. 2012. However, these accumulations are considered a "chemical time bomb" (Kabala & Szerszen 2002, Hovmand et al. 2008, because pollutants will eventually be leached into waterways (Miller & Friedland 1994).Increased deposition of sulfur and nitrogen compounds (SO2, NOx and NH3) in natural communities induces soil acidification (Falkengren-Grerup & Tyler 1993, Akselsson et al. 2013, Gao et al. 2013. Soil acidification depletes the basic nutrient cations, causes a decrease of pH, lowers the quality of humus, and accelerates the mobilization of aluminum (Boruvka et al. 2005, Miller & Watmough 2009). The depletion of basic cations from the forest floor alters the mineral nutrition of trees, modifies tree growth patterns (Klumpp et al. 2002, Högberg et al. 2006, Sebesta et al. 2011) and affects the distribution of roots (Joslin & Wolfe 1992). As a consequence, biodiversity, vegetation productivity and dynamics of the soil carbon pool are affected (Binkley et al. 2000).Altogether, such negative effects contribute to the forest decline observed in the Atlantic Rain Forest on the coastal mountain range named Serra do Mar (region of Cubatão, São Paulo State, Brazil). This forest is affected by air pollution from an industrial complex that caused destabilization of the land surface, disturbance of soil processes and landslides (Leitão Filho et al. 1993, Mayer et al. 2000a, 2000b. Furthermore, the large metropolitan regions of the São Paulo State (SE Brazil) are responsible for the intense fragmentation of...

“…In the present study, maximum litter production in dry months is consistent with the reports of other forest from similar environmental conditions (Sundarapandian and Swamy 1999;Tang et al 2010). These findings demonstrate that the variations of seasonal litterfall coincide with the rhythm of leaf senescence of the forest tree species along with the changes in annual environmental parameters (i.e., temperature and moisture) at a regional scale (Sundarapandian and Swamy 1999).…”

Litterfall and nutrient return in moist evergreen broad-leaved primary forest and mixed subtropical secondary deciduous broad-leaved forest in China

Litterfall plays an important role in carbon and nutrient cycling of a forest ecosystem which is generally affected by climate, vegetation, forest type and age. The majority of the subtropical forests of China are occurring in nutrient poor environment, and thus there is a need to understand the role of litterfall on the recycling of C and nutrients in these forests for their proper management. We measured litter production, and carbon and nutrient return in an evergreen broad-leaved primary forest (Mt. Ailao, SW China) and a deciduous broad-leaved secondary forest (Mt. Damei, East China). The annual litterfall productions were 1124 and 490 g m -2 at the primary evergreen forest and secondary deciduous forest, respectively. Carbon return in primary evergreen forest was approximately three times greater than that in secondary deciduous forest. Litter N concentrations in the secondary deciduous forest were higher than that of the primary evergreen forest and consequently, the use efficiency of N of the secondary deciduous forest was lower than the primary evergreen forest. This reflects a stronger nutrient conservation mechanism in the primary evergreen forest than in the secondary forest.

Government and international agencies have highlighted the need to focus global change research efforts on tropical ecosystems. However, no recent comprehensive review exists synthesizing humid tropical forest responses across global change factors, including warming, decreased precipitation, carbon dioxide fertilization, nitrogen deposition, and land use/land cover changes. This paper assesses research across spatial and temporal scales for the tropics, including modeling, field, and controlled laboratory studies. The review aims to (1) provide a broad understanding of how a suite of global change factors are altering humid tropical forest ecosystem properties and biogeochemical processes; (2) assess spatial variability in responses to global change factors among humid tropical regions; (3) synthesize results from across humid tropical regions to identify emergent trends in ecosystem responses; (4) identify research and management priorities for the humid tropics in the context of global change. Ecosystem responses covered here include plant growth, carbon storage, nutrient cycling, biodiversity, and disturbance regime shifts. The review demonstrates overall negative effects of global change on all ecosystem properties, with the greatest uncertainty and variability in nutrient cycling responses. Generally, all global change factors reviewed, except for carbon dioxide fertilization, demonstrate great potential to trigger positive feedbacks to global warming via greenhouse gas emissions and biogeophysical changes that cause regional warming. This assessment demonstrates that effects of decreased rainfall and deforestation on tropical forests are relatively well understood, whereas the potential effects of warming, carbon dioxide fertilization, nitrogen deposition, and plant species invasions require more cross-site, mechanistic research to predict tropical forest responses at regional and global scales.
