The conservation of saproxylic beetles in boreal forest [PDF]

, 2006
Forest management has altered the age structure, tree species composition and dead wood availability of Swedish boreal forests. As a consequence, many saproxylic (wood living) insect species have decreased in abundance and many species are threatened ...

Change in phylogenetic community structure during succession of traditionally managed tropical rainforest in southwest China. [PDF]

PLoS ONE, 2013
Tropical rainforests in Southeast Asia are facing increasing and ever more intense human disturbance that often negatively affects biodiversity. The aim of this study was to determine how tree species phylogenetic diversity is affected by traditional ...

Definition criteria determine the success of old-growth mapping

Ecological Indicators
Old-growth forests have been widely studied for decades. The extreme diversity of old forest characteristics has inspired an equally diverse set of old-growth definitions, and makes mapping old-growth difficult across large areas and different forest ...

Loss of deep roots limits biogenic agents of soil development that are only partially restored by decades of forest regeneration

Elementa: Science of the Anthropocene, 2018
Roots and associated microbes generate acid-forming CO2 and organic acids and accelerate mineral weathering deep within Earth’s critical zone (CZ). At the Calhoun CZ Observatory in the USA’s Southern Piedmont, we tested the hypothesis that deforestation ...

Environmental Stress Effects on Vigor, Mortality, and Growth in Northern Hardwood Forests Along a Pollution-Climate Gradient [PDF]

, 1998
Concern exists over the effects of interacting environmental stresses on the ecological integrity of temperate forests. Coincidence of sensitivity to drought, increasing occurrence of defoliation, and elevated pollutant deposition has produced ...

Reduced turnover rate of topsoil organic carbon in old-growth forests: a case study in subtropical China

Forest Ecosystems, 2021
Background Old-growth forests are irreplaceable with respect to climate change mitigation and have considerable carbon (C) sink potential in soils. However, the relationship between the soil organic carbon (SOC) turnover rate and forest development is ...

Commonality and Variability in the Structural Attributes of Moist Temperate Old-Growth Forests: a Global Review

, 2013
Temperate forests have been fundamentally altered by land use and other stressors globally; these have reduced the abundance of primary and old-growth forests in particular.

Vital rates and their multidecadal trends in the fir-beech old-growth forest of Badínsky prales

Journal of Forest Science, 2023
The study aimed to quantify annual mortality and recruitment rates on permanent research plots in the Badínsky prales old-growth forest. The data measured in four stands originate from six censuses, which together cover a 48-year period.

Mapping Individual Tree- and Plot-Level Biomass Using Handheld Mobile Laser Scanning in Complex Subtropical Secondary and Old-Growth Forests

Remote Sensing
Forests are invaluable natural resources that provide essential ecosystem services, and their carbon storage capacity is critical for climate mitigation efforts.

Soil Carbon Accumulation in Old-Growth Forests

, 2009
This chapter investigates the effect of forest age on soil carbon storage, clarifying if old-growth forests still store soil carbon despite the ecological theory that old-growth forests are carbon neutral.
