A century of National Forest Inventory in Norway – informing past, present, and future decisions

open access: yesForest Ecosystems, 2020
Past In the early twentieth century, forestry was one of the most important sectors in Norway and an agitated discussion about the perceived decline of forest resources due to over-exploitation was ongoing.

The complete chloroplast genome of Phyllostachys angusta McClure (Poaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2021
Phyllostachys angusta McClure is a precious wood-use bamboo resource, with almost straight stem. The complete chloroplast genome of the P. angusta McClure was assembled for the first time from Illumina pair-end sequencing data in this work.

Inventories to insights [PDF]

open access: yesThe Journal of Cell Biology, 2003
“In the long course of cell life on this earth it remained, for our age, for our generation, to receive the full ownership of our inheritance. We have entered the cell, the Mansion of our birth and started the inventory of our acquired wealth.” (Albert Claude, Nobel lecture, 1974)

Mapping forest age using National Forest Inventory, airborne laser scanning, and Sentinel-2 data

open access: yesForest Ecosystems, 2020
Background The age of forest stands is critical information for forest management and conservation, for example for growth modelling, timing of management activities and harvesting, or decisions about protection areas.

Estimating changes of forest carbon storage in China for 70 years (1949–2018)

open access: yesScientific Reports, 2023
In the realm of forest resource inventory and monitoring, stand-level biomass carbon models are especially crucial. In China, their importance is underscored as they form the bedrock for estimating national and international forest carbon storage.

Long-term dynamics of stand structure and regeneration in high-stocked selection fir-beech forest stand: Croatian Dinarides case study

open access: yesiForest - Biogeosciences and Forestry, 2021
In recent decades, changes in stand structure in Central European fir-beech forests, such as accumulation of large-diameter firs, fir dieback, and poor regeneration, have been well documented. Besides environmental factors, light harvesting was suggested

The Horizontal Distribution of Branch Biomass in European Beech: A Model Based on Measurements and TLS Based Proxies

open access: yesRemote Sensing, 2021
Forest biomass is currently among the most important and most researched target variables in forest monitoring. The common approach of observing individual tree biomass in forest inventory is to assign the total tree biomass to the dimensionless point of

Improving precision of field inventory estimation of aboveground biomass through an alternative view on plot biomass

open access: yesForest Ecosystems, 2020
We contrast a new continuous approach (CA) for estimating plot-level above-ground biomass (AGB) in forest inventories with the current approach of estimating AGB exclusively from the tree-level AGB predicted for each tree in a plot, henceforth called DA (

A new species of Nidirana (Anura, Ranidae) from northern Guangxi, China [PDF]

open access: yesZooKeys, 2022
A new species of music frog, Nidirana guibeiensis sp. nov., is described from northern Guangxi, China. Based on two mtDNA fragments analyzed, phylogenetic trees reveal that N. guibeiensis sp. nov. is most closely related to N. leishanensis.

Hindcasts of passerine density in arctic and subarctic Alaska suggest noncomplementary responses to shrub expansion by tundra- and shrub-adapted species

open access: yesArctic, Antarctic, and Alpine Research, 2022
Shrub expansion is among the most conspicuous of the warming-related phenomena occurring within tundra regions, but its effects on vertebrates are not well understood.
