The structure of spruce-fir tree stands mortality under impact of the Middle Ural copper smelter emissions [PDF]

open access: yesСибирский лесной журнал, 2015
The influence of industrial pollution on mortality values (dead fallen wood and dead standing trees) and its distribution by degrees of decomposition were investigated in spruce-fir forest stands in the vicinity of the Middle Ural copper smelter (the ...

The use of dead stand trees by birds: a prospective study in a Brazilian hydroelectric dam [PDF]

open access: yesBiota Neotropica, 2020
Abstract: Hydropower constructions cause severe disturbances to biodiversity. Arboreal plants die after flooding; however, they expose their emerged branches (also called paliteiros) as a new habitat for animals and plants. Nothing is known about how paliteiros influence the presence of aquatic birds.

Impacts of harvesting intensity on carbon allocation to species, size classes and pools in mangrove forests, and the relationships with stand structural attributes

open access: yesEcological Indicators, 2023
Mangroves are vital ecosystems that help mitigate climate change and natural hazards, despite representing only 0.5% of the world's coastlines. Recent studies have provided empirical evidence of the ongoing over-exploitation of mangrove forests in West ...

Standing-dead tree component of the boreal forest in central Saskatchewan

open access: yesForest Ecology and Management, 2000
Abstract The standing-dead tree component was assessed in part of the upland forests in the mixedwood boreal forest in central Saskatchewan. Comparisons of the average number of dead trees per hectare were made between softwood stands, softwood-dominant mixedwood stands, hardwood-dominant mixedwood stands and hardwood stands.

Comparison of Different Remotely Sensed Data Sources for Detection of Presence of Standing Dead Trees Using a Tree-Based Approach

open access: yesRemote Sensing, 2023
Deadwood is an important key ecological element for forest ecosystem biodiversity. Its low occurrence, especially in managed forests, makes inventory through field campaigns challenging. Remote sensing can provide a more objective and systematic approach to detect deadwood for large areas.

Fuel Dynamics Following Wildfire in US Northern Rockies Forests

open access: yesFrontiers in Forests and Global Change, 2020
Accumulation of dead woody material is a critical management concern following wildfires, especially given the possibility of subsequent wildfires. Forest structure and fuel accumulation are largely driven by site climatic conditions, so variability in ...

Wood Decay Characteristics and Interspecific Interactions Control Bacterial Community Succession in Populus grandidentata (Bigtooth Aspen)

open access: yesFrontiers in Microbiology, 2019
Few studies have investigated bacterial community succession and the role of bacterial decomposition over a continuum of wood decay. Here, we identified how (i) the diversity and abundance of bacteria changed along a chronosequence of decay in Populus ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Classification and clustering analysis of standing dead trees and associated park asset wildfire vulnerability in Yellowstone National Park

open access: yesForest Ecosystems
In the Rocky Mountain and Pacific Northwest regions of the United States, forests include extensive portions of standing dead trees. These regions showcase an intriguing phenomenon where the combined biomass of standing dead trees surpasses that of ...

Snag dynamic in a mixed Beech forest [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2010
Dead tree, which consisting of both standing dead tree and material that has fallen to the ground, is a dynamic resource in forest ecosystem. In order to investigate on falling and dynamic model of snags (standing dead trees) in a mixed beech forest ...
