Large‐scale and fine‐grained mapping of heathland habitats using open‐source remote sensing data

Remote Sensing in Ecology and Conservation, 2022
Mapping natural habitats remains challenging, especially at a national scale. Although new open‐access variables for vegetation and its environment and increased spatial resolution derived from satellite remote sensing data are available at the global ...

Seasonality, soil attributes and root biomass in cerrado, cerradão and forest environments, western Amazon

Bioscience Journal, 2022
The Amazon rainforest region presents a phytophysiognomy that ranges from savannas to cerrados, all of them intimately associated to climate and soil characteristics.

Optimum harvest maturity for Leymus chinensis seed

Biology Open, 2016
Timely harvest is critical to achieve maximum seed viability and vigour in agricultural production. However, little information exists concerning how to reap the best quality seeds of Leymus chinensis, which is the dominant and most promising grass ...

High-resolution estimation of air pollutant emissions from vegetation burning in China (2000–2018)

Frontiers in Environmental Science, 2022
Vegetation burning in China contributes significantly to atmospheric pollution and climate change. However, most recent studies have focused on forest fires, ignoring grassland fires.

Selecting dominant or rare tree species as habitat trees: Consequences for epiphyte diversity in temperate mountain forests

Trees, Forests and People
The retention of habitat trees, defined as large old trees saved from logging, is a key strategy for biodiversity conservation in production forests. Epiphytic bryophytes and lichens, which rely on the diverse microhabitats provided by large old trees ...

A new world natural vegetation map for global change studies

Anais da Academia Brasileira de Ciências, 2008
We developed a new world natural vegetation map at 1 degree horizontal resolution for use in global climate models. We used the Dorman and Sellers vegetation classification with inclusion of a new biome: tropical seasonal forest, which refers to both ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

THE RATE OF WATER EROSION AND ITS RELATION TO SOIL COVERAGE BY GRAVEL AND NATURAL VEGETATION [PDF]

Journal of Soil Sciences and Agricultural Engineering, 2004
Two Field experiments were carried out in Wadi-Maged, west Matrouh city, North Western Coastal Zone of Egypt (NWCZ), under natural rainfall conditions, during winter seasons 2001-2002 and 2002-2003, to evaluate the rate of water soil erosion under ...

Efficacy of Intermittent Theta‐Burst Stimulation for Prolonged Disorders of Consciousness: A Prospective, Randomized, Controlled Trial

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness

Dynamic Growth of “Pioneer Trees” as a Basis for Recreational Revitalization of Old Urban Landfills: A Case Study of Zgierz, Central Poland

Land
Urban tree biodiversity represents a valuable natural resource. However, some fast-growing tree species with limited esthetic value play an important ecological role by colonizing degraded areas, such as closed landfills.
