Abstract

Although arthropods are abundant and diverse in and on macrofungal sporocarps, their associations with fungi seldom have been described at a community level. We examined sporocarp-associated beetle communities in two primary sites in the Appalachian Mountains and foothills, assessing beetle diversity and abundance in relation to study site, sampling season (early vs. late summer), and sporocarp characteristics such as taxonomic position, dry mass and age. From 758 sporocarps representing >180 species we recovered 15404 adult beetles representing 72 species and 15 families, primarily Staphylinidae (> 98% of individuals and of 64% morphospecies). The probability of sporocarp colonization by beetles, beetle abundance and diversity differed among fungal species and were positively associated with sporocarp dry mass. Sporocarp age was positively correlated with beetle diversity and abundance (as measured in a focal species, Megacollybia platyphylla, Tricholomataceae), and its effects were independent of dry mass. Many beetle species were generalists, visiting a wide breadth of fungi in both the Agaricales and Polyporales; however, several beetle taxa showed evidence of specialization on particular fungal hosts. Host association data...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.
