Beeswax: Food and beyond

Food Biomacromolecules, EarlyView.
Abstract Honeybees (Apis mellifera L.) are an important class of insects that are the most beneficial in terms of economy. Beeswax is the second most important bee products after honey. Its commercial importance is due to its antimicrobial, antioxidant, anti‐inflammatory and antiseptic as well as regenerative properties.

Atmospheric mercury uptake to foliage using in situ and transplanted lichens at the New Almaden Mining District, California, United States

Frontiers in Environmental Chemistry
Contaminated soils at former mercury (Hg) mines release Hg into the atmosphere that can be absorbed by the surrounding foliage and potentially contribute to inputs of Hg to downstream reservoirs and the food chain.

Dwarf shrubs as bioindicators. [PDF]

Silva Fennica, 1981
Several studies of air polluted forest environments have shown that dwarf shrubs suffer from air pollution. In many cases the disturbances have been attributed to the susceptibility of the dwarf shrubs, while in some cases the vegetational competition factor has been discussed.

Bioindicators and environmental protection [PDF]

E3S Web of Conferences, 2020
The plants capable to occlude the maximum quantity of the heavy metals (HM) from soil solution are studied. Plants - indicators of accumulation of heavy metals are allocated, the new directions on decrease in toxicity of the soil are offered. For the purpose of studying of sorption abilities of bean herbs studied accumulation of heavy metals on phases ...

CO2 Fluxes and Soil Responses to Straw and Herbicide in Peanut

Land Degradation &Development, EarlyView.
ABSTRACT Peanut cultivation plays an important agronomic role in Brazil, especially in rotation with sugarcane, promoting biological nitrogen fixation and improving soil quality. This study aimed to test the hypothesis that the combined use of sugarcane mulch, peanut cultivation, and herbicide application would affect soil CO₂ fluxes, soil chemical ...

Exoplanet Characterization and the Search for Life [PDF]

, 2009
Over 300 extrasolar planets (exoplanets) have been detected orbiting nearby stars. We now hope to conduct a census of all planets around nearby stars and to characterize their atmospheres and surfaces with spectroscopy.

Improved COI taxonomic assignment workflow enhances detection of invertebrates in environmental DNA

Limnology and Oceanography: Methods, EarlyView.
Abstract Environmental DNA (eDNA) metabarcoding is an increasingly popular and powerful tool in ecology, offering a non‐invasive method to assess biodiversity and monitor ecosystem health across diverse environments. While the mitochondrial cytochrome c oxidase subunit I (COI) gene is one of the most widely used markers for studying eukaryotic ...
