Abstract The “Grain for Green” programme has had a significant impact on land use change
and carbon and nitrogen balance. However, it is unlear how vegetation restoration affects …

As a group, alpine plants stand among the least well studied organisms of terrestrial
ecosystems today. Misconceptions about poor biodiversity, small number of individuals per …

Recent increases in atmospheric carbon dioxide (CO 2) and temperature relieve the
limitation of these two on terrestrial ecosystem productivity, while nutrient availability …

We exploited the natural climate gradient in the northern hardwood forest at the Hubbard
Brook Experimental Forest (HBEF) to evaluate the effects of climate variation similar to what …

Elevation is one of key factors to affect changes in the environment, particularly changes in
conditions of light, water and heat. Studying the soil physicochemical properties and …

The aim of our studies was to determine the relation between temperature and the
respiration rate of the forest soil organic layer along an altitudinal gradient while controlling …

Chronically elevated deposition of reactive nitrogen (N), as ammonium (NH4+) and nitrate
(NO3−), in subtropical forests with monsoonal climate has caused widespread N leaching in …

Chronic N deposition to forests may induce N saturation and stand decline, leading to
reduced ecosystem N retention capacity, triggered by a shift from N limitation of trees to …

Sulfur (S) is an important macronutrient that is widely distributed in nature. Understanding
the patterns and mechanisms of S dynamics is of great significance for accurately predicting …
