Bare Land Referenced Algorithm from Hyper-Temporal Data (BRAH) for Land Use and Land Cover Age Estimation

open access: yesLand, 2023
Determining the age of land use and land cover (LULC) using satellite imagery has long been one of the challenging tasks in remote sensing research. Accurately determining age, especially crop age, is essential for plot management, biomass calculations ...

Antelope Bitterbrush Seed Production and Stand Age [PDF]

open access: yesJournal of Range Management, 2001
Antelope bitterbrush (Purshia tridentata (Pursh) DC) is the most important browse species on many western mule deer (Odocoileus hemionus) ranges. Lack of antelope bitterbrush seedling recruitment is a critical problem, and therefore, the influence of livestock grazing on antelope bitterbrush seed production is an important issue.

Tree size variation induced by stand age mainly regulates aboveground biomass across three major stands of temperate forests in South Korea

open access: yesFrontiers in Forests and Global Change, 2023
Forest biomass and biodiversity are the most important elements of forest functions and ecosystem services. In this study, we explore the possibilities and ways to enhance ecosystem functions and services related to biomass and biodiversity.

Reforestation regulated soil bacterial community structure along vertical profiles in the Loess Plateau

open access: yesFrontiers in Microbiology, 2023
IntroductionReforestation is a widely used strategy for ecological restoration in areas facing ecological degradation. Soil bacteria regulate many functional processes in terrestrial ecosystems; however, how they respond to reforestation processes in ...

Transforming even-aged coniferous stands to multi-aged stands: an opportunity to increase tree species diversity? [PDF]

open access: yesForestry: An International Journal of Forest Research, 2020
Abstract Transforming even-aged coniferous stands into multi-aged ones is attracting growing interest in Europe. However, applying this silvicultural treatment, maintaining a continuous cover and relying on natural regeneration require a deep understanding of the factors driving interspecific competition in the understorey. In particular,

Changes in Bulk and Rhizosphere Soil Microbial Diversity and Composition Along an Age Gradient of Chinese Fir (Cunninghamia lanceolate) Plantations in Subtropical China

open access: yesFrontiers in Microbiology, 2022
Soil microorganisms play key roles in biogeochemical cycling in forest ecosystems. However, whether the responses of microbial community with stand development differed in rhizosphere and bulk soils remains unknown. We collected rhizosphere and bulk soil

Healthy aging—would cytotoxic T lymphocytes stand out?

open access: yesCell Death Discovery, 2023
Senescent cells (SnCs) accumulate in multiple tissue types with the process of individual aging, hindering tissue renewal and driving multiple aging-related disorders. Aside from senescence-associated secretory phenotype (SASP) neutralization and senolytics, there is an emerging senolysis strategy to eliminate SnCs by mobilizing the immunosurveillance ...

Estimating the Aboveground Biomass for Planted Forests Based on Stand Age and Environmental Variables

open access: yesRemote Sensing, 2019
Measuring forest aboveground biomass (AGB) at local to regional scales is critical to understanding their role in regional and global carbon cycles. The Three-North Shelterbelt Forest Program (TNSFP) is the largest ecological restoration project in the ...
