Abstract

The electric net trap made of 3 rows of polyethylene net fence with the high voltage electric pulse was examined in the field for capturing the venomous snake, Trimeresurus flavoviridis. The bottom of the center row of the net fence was buried in the ground and that of other two outer rows was partially free from the ground so that snakes were allowed to invade one way into the spaces at both sides of the center net. The examination using a 90 m net trap set for 116 days resulted in the capture of 44 snakes, i.e., 7 T. flavoviridis, 7 Dinodon semicarinatus and 33 Opheodrys semicarinatus, of which the latter two were nonvenomous. The result indicated that the net trap was an efficient tool for capturing snakes and in identifying the direction of snake movement. In the other studies conducted in 1982 and 1983, a 178.5 m net trap was set at a part of a 2,000 m electric net barrier, which surrounded a 12.8 ha sugar cane field and thereby prevented snake invasion. The number of venomous snakes captured by the inner net trap was remarkably reduced from 13 in 1982 to 0 in 1983, in contrast to 8 and 9, respectively, observed in the outer trap. The decrease of snake population was also observed in 100 box traps baited with a live rat se...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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
