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.

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 (

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

Is There News in Inventories? [PDF]

open access: yesSSRN Electronic Journal, 2020
This paper identifies total factor productivity (TFP) news shocks using standard VAR methodology and documents a new stylized fact: in response to news about future increases in TFP, inventories rise and comove positively with other major macroeconomic aggregates.

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

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.

Ants in the clouds: A preliminary checklist of the ant (Hymenoptera, Formicidae) fauna of a Honduran cloud forest ecosystem, featuring a key to country genera [PDF]

open access: yesNeotropical Biology and Conservation
Ant diversity in tropical montane rainforests is globally understudied. This is true for Cusuco National Park (CNP), a cloud forest ecosystem in northwestern Honduras that supports geographically isolated and threatened habitats.

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.

open access: yesZooKeys, 2023
Four new species of Araneus Clerck, 1757 from southern China are described: A. mayanghe Mi & Wang, sp. nov. (♂♀) from Guizhou, A. shiwandashan Mi & Wang, sp. nov. (♂♀) from Guangxi, and A. zhoui Mi & Wang, sp. nov.
