Woodpeckers can act as dispersal vectors for fungi, plants, and microorganisms

open access: yesEcology and Evolution, 2021
Bird‐mediated dispersal is presumed to be important in the dissemination of many different types of organisms, but concrete evidence remains scarce. This is especially true for biota producing microscopic propagules.

A new genus, Desertispora, and a new species, Diversispora sabulosa, in the family Diversisporaceae (order Diversisporales, subphylum Glomeromycotina) [PDF]

open access: yes, 2018
Phylogenetic analyses of sequences of the SSU-ITS-LSU nrDNA segment and the RPB1 gene showed that the arbuscular mycorrhizal fungus originally described as Diversispora omaniana does not belong to the genus Diversispora, but represents a separate clade ...

Survival of thermophilic spore-forming bacteria in a 90+ year old milk powder from Ernest Shackelton's Cape Royds Hut in Antarctica [PDF]

open access: yes, 2000
Milk powder taken to Antarctica on Shackelton's British Antarctic Expedition in 1907 was produced in New Zealand by a roller drying process in the first factory in the world dedicated to this process. Thermophilic bacilli are the dominant contaminants of

Aspergillus niger Spores Are Highly Resistant to Space Radiation [PDF]

open access: yes, 2020
The filamentous fungus Aspergillus niger is one of the main contaminants of the International Space Station (ISS). It forms highly pigmented, airborne spores that have thick cell walls and low metabolic activity, enabling them to withstand harsh ...

Conservation of the “Outside-in” Germination Pathway in Paraclostridium bifermentans

open access: yesFrontiers in Microbiology, 2018
Clostridium difficile spore germination is initiated in response to certain bile acids and amino acids (e.g., glycine). Though the amino acid-recognizing germinant receptor is unknown, the bile acid germinant receptor is the germination-specific ...

UV Disinfection sensitivity index of spores or protozoa: A model to predict the required fluence of spores or protozoa

open access: yesWater Science and Technology, 2022
During UV disinfection, the required UV dose in terms of fluence depends upon the species of bacteria spore and protozoa. To rank their UV disinfection sensitivity, spore sensitivity index (SPSI) and protozoan sensitivity index (PSI) are defined.
