“…Same trend was also reported in past studies (Pragasan and Parthasarathy, 2005;Doughty et al, 2013;Malhi et al, 2014). This is likely to be related to the low soil moisture level during this period resulted due to a strong and continuous solar radiation.…”

“…Malhi et al (2014) reported almost same range of 72-74% allocation in leaf fall while Girardin et al (2014) reported a range of 69-73%. The higher percentage of leaf litter and lower percentage of non-leaf litter in DF as compared to UF may be linked to the lopping of tree twigs for fodder which prevents the plant from flowering and fruiting, thereby reducing the quantity of non-leaf litter.…”

Litterfall is an important vector of nutrient and carbon recycling in forest ecosystems. Present study was conducted in moist tropical forest of eastern Nepal to understand the effect of disturbance on litter dynamics. Litterfall was estimated at monthly intervals from one litter trap (1 m × 1 m) at each of the 70 sampling plots while litter mass accumulated at each sampling plot was collected once every season from one 1 m × 1 m plot. The total annual litterfall in undisturbed forest (UF) was 11.8 Mg ha −1 yr −1 which decreased by 54.2% in disturbed forest (DF). Leaves accounted for 69% (UF) to 76% (DF) of total litterfall while non-leaf litter formed the rest. Seasonal pattern exhibited a concentrated litterfall in summer season during March to June when more than 70% litterfall occurred in both stands. Forest floor litter mass also decreased due to forest disturbance. The total input of nutrients to the soil through litterfall in UF was more than double as compared to DF. The nutrient stocks in litter mass were in the order: N > K > P in both stands. Key disturbance activities like lopping, litter removal, tree felling, grazing, fire etc. in the peripheral part of the forest should be strictly prohibited by imposing rules and regulations so that status of biodiversity would be restored.

“…Therefore, Malhi et al [2014] suggested that phenological rhythms rather than direct climatic controls (such as water stress) seasonally drive tropical NPP allocation in Amazonian lowland forests. In accordance, the strong seasonality in NPP of Peruvian montane forests was reported to be driven by changes in photosynthesis and variation in solar radiation, such that trees invested more in biomass production in the cooler season with lower solar radiation and more in maintenance during the warmer high solar radiation period [Girardin et al, 2013]. As a result, temporal or spatial variation in the allocation of NPP between wood, canopy, and fine roots could have the potential to be an important feature determining the C sink strength of tropical forest ecosystems [Doughty et al, 2014].…”

The productivity of tropical forests is driven by climate (precipitation, temperature, and light) and soil fertility (geology and topography). While large-scale drivers of tropical productivity are well established, knowledge on the sensitivity of tropical lowland net primary production to climate anomalies remains scarce. We here analyze seven consecutive years of monthly recorded tropical forest aboveground net primary production (ANPP) in response to a recent El Niño-Southern Oscillation (ENSO) anomaly. The ENSO transition period resulted in increased temperatures and decreased precipitation during the El Niño dry period, causing a decrease in ANPP. However, the subsequent La Niña wet period caused strong increases in ANPP such that drought-induced reductions were overcompensated. Most strikingly, the climatic controls differed between canopy production (CP) and wood production (WP). Whereas CP showed strong seasonal variation but was not affected by ENSO, WP decreased significantly in response to a 3°C increase in annual maximum temperatures during the El Niño period but subsequently recovered to above predrought levels during the La Niña period. Moreover, the climate sensitivity of tropical forest ANPP components was affected by local topography (water availability) and disturbance history (species composition). Our results suggest that projected increases in temperature and dry season length could impact tropical carbon sequestration by shifting ANPP partitioning toward decreased WP, thus decreasing the carbon storage of highly productive lowland forests. We conclude that the impact of climate anomalies on tropical forest productivity is strongly related to local site characteristics and will therefore likely prevent uniform responses of tropical lowland forests to projected global changes.

“…Despite this requirement, most of the past studies in tropical forests are found to be limited to analyzing the aboveground systems (Chave et al 2008;Djomo et al 2011;Malhi et al 2011;Doughty et al 2013;Ngo et al 2013;Girardin et al 2014;Malhi et al 2014) and only a few studies concern to the belowground aspects (Ibrahima et al 2010;Powers and Perez-Aviles 2013;Noguchi et al 2014).…”

Background: Forest biomass is helpful to assess its productivity and carbon (C) sequestration capacity. Several disturbance activities in tropical forests have reduced the biomass and net primary production (NPP) leading to climate change. Therefore, an accurate estimation of forest biomass and C cycling in context of disturbances is required for implementing REDD (Reducing Emissions from Deforestation and Forest Degradation) policy. Methods: Biomass and NPP of trees and shrubs were estimated by using allometric equations while herbaceous biomass was estimated by harvest method. Fine root biomass was determined from soil monolith. The C stock in vegetation was calculated by multiplying C concentration to dry weight.
