Effect of rainfall events on soil carbon flux in mountain

To address this issue, we studied the characteristics of soil carbon flux and soil moisture content related to rainfall events in mountain pastures converted from deciduous forest in Korea.

Temperate forest Environment | Britannica

Temperate forest Temperate forest Environment: Winter in the temperate latitudes can present extremely stressful conditions that greatly affect the vegetation. The days are shorter and temperatures are low, so much so that in many places leaves are unable to function for long periods and are susceptible to damage from freezing. These conditions reduce the photosynthetic activity of the trees.

Soil respiration in temperate forests is increased by a

1. Introduction. Temperate forest soils represent important soil organic carbon (SOC) pools (Lal, 2008; Tyrrell et al., 2012) that can be greatly influenced by changes in soil organic matter (SOM) decomposition resulting from changes in fresh plant leaf inputs (i.e., litter) (Boone et al., 1998; Gunina and Kuzyakov, 2015).Labile litter inputs serve as readily available energy sources for soil

Declines in methane uptake in forest soils | PNAS

Aug 21, 2018· Abstract. Forest soils are a sink for atmospheric methane (CH 4) and play an important role in modulating the global CH 4 budget. However, whether CH 4 uptake by forest soils is affected by global environmental change is unknown. We measured soil to atmosphere net CH 4 fluxes in temperate forests at two long-term ecological research sites in the northeastern United States from the late

Long-term forest soil warming alters microbial communities

Mounting evidence suggests that soil microbes play a role in elevated CO 2 emissions and soil organic matter loss that is symptomatic of long-term warming in temperate forest ecosystems (Bardgett et al., 1999; Schimel and Gulledge, 2004; Frey et al., 2008, 2013). We set out to test the primary hypothesis that the soil bacterial community is

A good example is soil limiting factor; N is the soil limiting factor in temperate ecosystems while P is the limiting factor in tropical forests [6, 18]. Also, competition, which influences species diversity, tends to play a more important role in temperate forests compared to tropical forests due to niche partitioning by plants that occurs in

Temperate Deciduous Forest (Biome) Climate, Location

May 18, 2017· Temperate Deciduous Forest Definition. A temperate deciduous forest is a biome that has many deciduous trees which drop their leaves in the fall. These forests are also known as broad-leaf forests because the trees have wide, flat leaves.Temperate deciduous forests lie in the mid-latitude areas of the Earth, between the Arctic poles and the tropics.

SUMMARY The ecology of forest soils is an important field of research due to the role of forests as carbon sinks. Consequently, a significant amount of information has been accumulated concerning their ecology, especially for temperate and boreal forests. Although most studies have focused on fungi, forest soil bacteria also play important roles in this environment.

Soils under rainforest do not contain many nutrients, and these are tied up in the complex interactive system of soil and forest. Nutrient recycling refers to the decomposition of litter and the very rapid mineralization of released nutrients which are absorbed by plant roots. The nutrients in the system are basically stored in living vegetation.
