Estimating aboveground live understory vegetation carbon in the United States

Environmental Research Letters, 2017
Despite the key role that understory vegetation plays in ecosystems and the terrestrial carbon cycle, it is often overlooked and has few quantitative measurements, especially at national scales. To understand the contribution of understory carbon to the United States (US) carbon budget, we developed an approach that relies on field measurements of ...

Synergistic adaptation strategies involving aboveground vegetation and the soil seed bank in the Gurbantunggut Desert

Global Ecology and Conservation
The sustainability of desert ecology depends on synergistic changes in the aboveground and soil seed banks. To explain this process, we undertook fieldwork in the largest fixed-semifixed desert in China, the Gurbantunggut Desert.

Soil Seed Bank of Two Karst Ecosystems in Bogor, Indonesia: Similarity with the Aboveground Vegeta-tion and Its Restoration Potential

Journal of Tropical Life Science, 2017
Karst ecosystem in Bogor is currently threatened by mining activities. Restoration of the disturbed karst areas is urgently required. Seed banks are considered as an important potential seed sources for restoration.

Use of hyperspectral reflectance to non-destructively estimate seagrass Zostera noltei biomass

Ecological Indicators, 2021
Seagrasses are marine plants ranked worldwide amongst the most valuable coastal ecosystems. The global conservation effort requires accurate estimation of seagrass abundance and taxonomic composition.

Aboveground vegetation and perennial grass seed bank in arid rangelands disturbed by grazing

Rangeland Ecology & Management, 2014
Recruitment by seeds can be an important mechanism for recovery of plant communities following disturbance. Our objective was to assess the density and spatial patterning of perennial grass (highly preferred by herbivores) seeds in litter patches at locations with different aboveground vegetation structure in sites with different grazing history ...

Feedbacks between vegetation and soil in global Forest degradation: a meta-analysis

Ecological Indicators
Forest degradation represents a major global environmental challenge, yet its impacts on both aboveground vegetation and belowground soil properties remain insufficiently understood.

Protected areas reduce deforestation and degradation and enhance woody growth across African woodlands

Communications Earth & Environment, 2023
Protected areas are increasingly promoted for their capacity to sequester carbon, alongside biodiversity benefits. However, we have limited understanding of whether they are effective at reducing deforestation and degradation, or promoting vegetation ...

Dynamic Monitoring Method for Aboveground Biomass of Maize Based on Multi-source Data

应用气象学报
The aboveground biomass of maize is regarded as a crucial indicator for monitoring maize growth. However, it's challenging to meet the practical needs for dynamic remote sensing of aboveground biomass during early growth stages.

Spatial patterns of arctic tundra vegetation properties on different soils along the Eurasia Arctic Transect, and insights for a changing Arctic

Environmental Research Letters, 2020
Vegetation properties of arctic tundra vary dramatically across its full latitudinal extent, yet few studies have quantified tundra ecosystem properties across latitudinal gradients with field-based observations that can be related to remotely sensed ...

Bimodality of woody cover and biomass across the precipitation gradient in West Africa [PDF]

Earth System Dynamics, 2014
Multiple states of woody cover under similar climate conditions are found in both conceptual models and observations. Due to the limitation of the observed woody cover data set, it is unclear whether the observed bimodality is caused by the presence of ...
