Introduction to Secondary Tropical

In this study we use end-member mixing analysis (EMMA) of stream chemistry, and hydrometric characterizations of hillslope soil moisture to identify hydrologic flowpaths in humid tropical steep-land catchments of varying LULC-mature tropical forest, young secondary tropical forest, cattle pasture.

Here, we applied 15 N tracers to examine the fates of deposited ammonium (NH4 + ) and nitrate (NO3 - ) separately over three years in a primary and a secondary tropical montane forest in southern China.

Secondary tropical forests and coffee agroforestry systems contain fewer trees than native forests but can positively impact soil hydrological functions, such as water infiltration compared to the pasture land that they replace.

This seemed to simulate a quick transition from primary succession (consist of bare rock and cannot support any plant life) to mid-stage of secondary tropical rainforest succession (many fast-growing pioneer tree species induced high soil water and nutrient loss).

Results from a Principal Component Analysis (PCA) indicated number of gaps to be a major driver associated with the occurrence of oil palm plantations, while higher values of key structural metrics, such as top height, LAI and ENL were strongly linked with the presence of secondary tropical forest plots.

This plant easily grows in various habitats, including tropics areas, such as secondary tropical rain forest located in Mempawah District, West Kalimantan (Borneo), Indonesia.

We hypothesized that much higher transpiration rate of fast-growing tree species would deplete soil water more than the dominant slow-growing species in the adjacent secondary tropical rain forest during both wet and dry seasons, thereby resulting in much lower soil water content.

We measured hourly R s in a secondary tropical moist forest in Puerto Rico over a 3‐year period to (a) quantify the magnitude of R s and (b) identify the role of climatic, substrate, and nutrient controls on the seasonality of R s.

We analyze here how much carbon is being accumulated annually by secondary tropical dry forests (TDFs) and how structure, composition, time since abandonment, and climate can influence the dynamics of forest carbon accumulation.

Here we examine the changes in the potential supply of ecosystem services and the interactions among them along secondary tropical dry forest succession for a site on the Mexican Pacific coast.

Our data suggested that a substantial acceleration of soil N2O flux was mainly determined by the increasing availability of inorganic N stimulated by the improved litter quality (low C:N ratio), as well as elevated gravimetric water content, and net N mineralization and nitrification during the spontaneous succession of secondary tropical forests after slash-and-burn agriculture.

Herein, we compare the diversity and species composition of orb-weaving spiders in a primary and a secondary tropical dry forest in northern Colombia.

The distribution of rosulate and acaulescent aroid epiphytes were determined in multiple stands of old growth and secondary tropical forests at La Selva.

Secondary tropical forests offer critical ecosystem services such as regulation of climate, soil and water resources, which are frequently traded off against the provision of forest products for human use or repeated clearing for agriculture.

A large area of secondary tropical montane rainforest in recovery was retained in Bawangling National Nature Reserve after disturbance.

The Source-Disperser Limitation Framework (SDLF) provides a way to better predict secondary tropical forest succession across gradients of landscape disturbance by integrating seed sources and frugivore behavior.

piscipula was measured in a semi-evergreen secondary tropical forest of the Andres Quintana Roo ejido, Quintana Roo.

92 tons/ha with the largest value in the secondary tropical forest of 732.

One way to assist stabilising and reducing CO2 is to promote secondary tropical forest regrowth on abandoned agricultural land.

Predictable nutrient recuperation across a diverse and productive ecosystem may support future forest growth and could provide a means to quantify successful restoration of ecosystem function in secondary tropical forest beyond biomass or species composition.

Here, we conducted a 3-year N addition experiment with four treatments (0, 20, 50, and 100 kg N ha−1 year−1) in a primary and secondary tropical montane forest in Hainan Island, China, to explore the effects of elevated N availability on soil microbial community composition.

We found that phylogenetic diversity, soil fertility and elevation gradients were strongly predictive of AGB in a secondary tropical montane forest in Southeast Asia.

In a moderately hilly landscape covering mature and secondary tropical dry forests we surveyed 454 sites for presence or absence of frost-induced tree mortality.

One of the files contains information about secondary tropical forest of 25 years old, along the slopes of the volcano Turrialba (from 600 to 2700 meters above sea level).

The species is terrestrial or epipetric on riverbanks, often growing as a rheophyte, at low to mid elevations in primary and secondary tropical humid forests.

In some secondary tropical forests, however, potentially ECM trees belonging to Tristaniopsis (Myrtaceae) become dominant and may help ECM dipterocarp forests to recover.

All sampled groups were found in secondary tropical rainforest, often dominated by either native bamboo or cane species.

Litterfall and top soil were sampled from each of the five 20 × 20 m plots established in the primary (PTF) and secondary tropical forests (STF), at monthly interval for one year.
