The nutrient cycling is influenced by the successional stage. However, there is disagreement in relation to the pattern of this dynamic. The present study aimed to evaluate the chemical attributes of the topsoil and litterfall in two abandoned ...

Abstract Understanding spatial variation in grassland productivity is critical for ecological modeling and management. The Great Plains of North America, a vast grassland region east of the Rocky Mountains, exhibits strong gradients in aboveground net primary production (ANPP) linked to precipitation and finer scale topoedaphic variation.

Seasonality of litterfall and leaf decomposition in a cerrado site [PDF]
We investigated annual litterfall and leaf decomposition rate in a cerrado site. We collected woody plant litter monthly from April 2001 to March 2002 and from July 2003 to June 2004. We placed systematically 13 litter traps (0.5 x 0.5 m) in a line, 10 m one from the other.

Controls on carbon and energy exchange by a black spruce - moss ecosystem: Testing the mathematical model Ecosys with data from the BOREAS experiment [PDF]
Stomatal limitations to mass and energy exchange over boreal black spruce forests may be caused by low needle N concentrations that limit CO2 fixation rates.

Soil conditions are critical factors shaping forest structure and tree species composition in seasonally dry tropical forests (SDTFs); however, few studies have evaluated edaphic effects in Cambodia's unique lowland forest landscape, where different forest types coexist under similar climatic conditions.

Read the free Plain Language Summary for this article on the Journal blog. Abstract In agroecosystems, it is well known that nitrogen (N) can be transferred below‐ground among plants, especially between legumes and forage crops. However, we still lack a deep mechanistic understanding of this ecological process and its implications in plant communities,

Ice storm effects on the canopy structure of a northern hardwood forest after 8 years [PDF]
Ice storms can cause severe damage to forest canopies, resulting in differential mortality among tree species and size classes and leading to long-lasting changes in the vertical structure and composition of the forest.

NUTRIENT RETURN THROUGH LITTERFALL IN A Eucalyptus dunnii Maiden STAND IN SANDY SOIL
In a forest stand, litterfall is primarily responsible for the retention and return of nutrients to the soil. The objective of this study was to evaluate the return of nutrients through litterfall in a stand of Eucalyptus dunnii in a Pampa biome.

Biodiversity enhances stream ecosystem efficiency, with greater taxonomic and trait diversity improving functions like decomposition. Shredder diversity arises from both species differences and ontogenetic variation. We experimentally examined these factors to reveal how they shape the magnitude and timing of organic matter processing in streams ...
