Structural composition of organic matter in particle-size fractions of soils along a climo-biosequence in the main range of Peninsular Malaysia

open access: yesOpen Geosciences, 2016
Information on structural composition of organic matter (OM) in particle-size fractions of soils along a climo-biosequence is sparse. The objective of this study was to examine structural composition and morphological characteristics of OM in particle ...

Organic carbon and microbiome in tundra and forest–tundra permafrost soils, southern Yamal, Russia

open access: yesPolar Research, 2021
Permafrost soils differ significantly from other soils because they serve as a huge reservoir for organic carbon accumulated during the Quaternary Period, which is at risk of being released as the Arctic warms.

The use of chronosequences in studies of ecological succession and soil development [PDF]

open access: yes, 2010
1. Chronosequences and associated space-for-time substitutions are an important and often necessary tool for studying temporal dynamics of plant communities and soil development across multiple time-scales.

Termite Ecology in the First Two Decades of the 21st Century: A Review of Reviews

open access: yesInsects, 2019
Termite ecology came of age in 1978 with the seminal review of Wood and Sands which by considering the quantitative contributions made by termites to the carbon cycle at the landscape level concluded that they were major players in tropical ecosystems ...

Incipient ferralization and weathering indices along a soil chronosequence in Taiwan [PDF]

open access: yes, 2016
The low hilly topography of Green Island, a volcanic island off southeastern Taiwan, includes an altitudinal sequence of sub-horizontal benches. We examined eight profiles along this sequence, ranging from pale brown loamy coral sand on the lowest bench ...

Integrating effects of species composition and soil properties to predict shifts in montane forest carbon-water relations. [PDF]

open access: yes, 2018
This study was designed to address a major source of uncertainty pertaining to coupled carbon-water cycles in montane forest ecosystems. The Sierra Nevada of California was used as a model system to investigate connections between the physiological ...

Soil Fertility Changes With Climate and Island Age in Galápagos: New Baseline Data for Sustainable Agricultural Management

open access: yesFrontiers in Environmental Science, 2021
While the extended absence of human influence has led to matchless natural conditions on the Galápagos archipelago, agricultural activities on the inhabited islands are increasingly affecting soil health and functioning.
