Habitat selection of an old‐growth forest specialist in managed forests [PDF]

open access: yesAnimal Conservation, 2020
AbstractOld‐growth forest specialists are among the species most affected by commercial forestry. However, it is often unclear whether such species can persist and what their habitat needs are in managed forests. We investigated habitat selection of one such old‐growth forest specialist, the white‐backed woodpeckerDendrocopos leucotos, a species highly

Stand structure attributes in potential Old-Growth Forests in the Apennines, Italy [PDF]

open access: yes, 2011
The aim of this paper is to provide early feedback on stand structure attributes in Italian Apennines forests that could be considered Old Growth Forests in the Mediterranean Eco-Region. Few data are nowadays available relating to this Region.

The roles of plant pathogens in old-growth forests

open access: yesBucovina Forestieră, 2022
Old-growth forests are considered a benchmark for naturalness and models to which one compares managed forests, comparison leading to debates around biodiversity and its conservation, structure and dynamics, polarizing conservationists and forest ...

Nutrient limitation in three lowland tropical forests in southern China receiving high nitrogen deposition: insights from fine root responses to nutrient additions.

open access: yesPLoS ONE, 2013
Elevated nitrogen (N) deposition to tropical forests may accelerate ecosystem phosphorus (P) limitation. This study examined responses of fine root biomass, nutrient concentrations, and acid phosphatase activity (APA) of bulk soil to five years of N and ...

Living and Dead Aboveground Biomass in Mediterranean Forests: Evidence of Old-Growth Traits in a Quercus pubescens Willd. s.l. Stand [PDF]

open access: yes, 2017
For a long time, human impact has deeply simplified most of the forest ecosystems of the Mediterranean Basin. Here, forests have seldom had the chance to naturally develop a complex and multilayered structure, to host large and old trees and rich ...

In Site Soil Seed-Banks: Size, Composition and Persistence across Tropical Successional Stages

open access: yesPlants, 2023
I investigated the size, composition and persistence of the seed-bank in primary forests, secondary forests and old-fields in southern Mexico. I also assessed the contribution of the seed-bank to regeneration relative to other propagule sources.

Land snail diversity can reflect degrees of anthropogenic disturbance [PDF]

open access: yes, 2013
Faunal indicators of old-growth forests in heavily-disturbed regions are virtually non-existent. However, land snails, in particular micro-snails, could reflect the impact of land-use on ecosystem integrity.

Old growth Afrotropical forests critical for maintaining forest carbon [PDF]

open access: yesGlobal Ecology and Biogeography, 2020
AbstractAimLarge trees [≥ 70 cm diameter at breast height (DBH)] contribute disproportionately to aboveground carbon stock (AGC) across the tropics but may be vulnerable to changing climate and human activities. Here we determine the distribution, drivers and threats to large trees and high carbon forest.LocationCentral Africa.Time periodCurrent.Major ...

The role of old-growth forests in frequent-fire landscapes [PDF]

open access: yes, 2007
Classic ecological concepts and forestry language regarding old growth are not well suited to frequent-fire landscapes. In frequent-fire, old-growth landscapes, there is a symbiotic relationship between the trees, the understory graminoids, and fire that
