Abstract

In a forest ecosystem, the major pathway for carbon and nutrient cycling is through litterfall, which has been influenced by physical and biological factors. The purpose of this study was to investigate monthly litterfall production in three forests in Jeju Island differentiated based on precipitation and forest composition: Chungsu (Quercus glauca as the dominant species; low precipitation), Seonheulb (Q. glauca as the dominant species; high precipitation), and Seonheulm (Q. glauca and Pinus thunbergii as the dominant species; high precipitation). Litterfall was collected monthly from April to December 2015 and divided into leaf litter, twig, bark, seeds, and unidentified materials. The amount of leaf litter by species varied by stand, but leaf litter and total litterfall were very similar among stands, ranging from 362 g m-2 to 375 g m-2 for leaf litter and 524 g m-2 to 580 g m-2 for total litterfall. However, oak leaf litter was the highest in May, but needle litter was the highest in December. Forest type and climate factor had no influence on the amount of litterfall in the studied forests while the litterfall production by species showed considerable seasonal variation, resulting in varying effects on carbon and nutrient ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
