Soil nitrogen dynamics during stand development after clear-cutting of Japanese cedar (Cryptomeria japonica) plantations [PDF]

, 2011
We examined soil N dynamics, including inorganic N concentration, net N transformation rates, and estimated plant N uptake (EPNU) from soil N budgets, and litterfall inputs, in five Japanese cedar plantation stands of different ages (5, 16, 31, 42, and ...

A New Perspective of Trees Competition Network Research [PDF]

E3S Web of Conferences
Forest competition is a key factor driving forest dynamics and stand structure, and is one of the core issues in ecological research. Competition is a complex ecological process with temporal changes, which is interrelated and affected with forest growth,

Natural Disturbances Regime as a Factor of Korean Pine-Broadleaved Forest Stand Shaping in the South of the Russian Far East [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2015
Using dendroecological approach we reconstructed disturbance history of a mixed Korean pinebroadleaved stand in the south of the Russian Far East. Our results show that during the last two centuries there were no mass disturbances, which may lead to ...

Long-term dynamics of stand structure and regeneration in high-stocked selection fir-beech forest stand: Croatian Dinarides case study

iForest - Biogeosciences and Forestry, 2021
In recent decades, changes in stand structure in Central European fir-beech forests, such as accumulation of large-diameter firs, fir dieback, and poor regeneration, have been well documented. Besides environmental factors, light harvesting was suggested

Natural development of stand structure in peatland Scots pine following drainage: results based on long-term monitoring of permanent sample plots

Silva Fennica, 2004
We studied the dynamics of stand structure on drained peatland sites in Scots pine dominated stands untreated with thinnings. The data consisted of consecutive stand measurements in 10 permanent sample plots where the monitoring periods varied from 29

Spatial Analysis of a mixed Beech, Spruce and Fir stand in the Eastern Alps [PDF]

, 2010
In a forest reserve, located in the Eastern Italian Alps, a 4 ha permanent plot has been set up in a beech-spruce-fir multilayered forest, left to natural evolution for more than 30 years, in order to detect stand structure and spatial patterns ...

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...
