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

Ecology 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.

Spore Germination

Microbiology Spectrum, 2015
ABSTRACT Despite being resistant to a variety of environmental insults, the bacterial endospore can sense the presence of small molecules and respond by germinating, losing the specialized structures of the dormant spore, and resuming active metabolism, before outgrowing into vegetative cells.

Fern spore viability considered in relation to the duration of the Cretaceous-Paleogene (K-Pg) impact winter. A contribution to the discussion

Acta Palaeobotanica, 2019
The Cretaceous-Paleogene (K-Pg) boundary Chicxulub impact is supposed to have produced a nearly decade-long impact winter which resulted in a mass-extinction event among dicot angiosperms but which left pteridophytes comparatively unaffected.

Transcriptional analysis of temporal gene expression in germinating Clostridium difficile 630 endospores. [PDF]

, 2013
Clostridium difficile is the leading cause of hospital acquired diarrhoea in industrialised countries. Under conditions that are not favourable for growth, the pathogen produces metabolically dormant endospores via asymmetric cell division.

Site-specific factors influencing Hymenoscyphus fraxineus spore dispersal: the role of understorey vegetation and slope steepness in ash dieback spread

Notulae Botanicae Horti Agrobotanici Cluj-Napoca
Ash dieback (ADB), caused by Hymenoscyphus fraxineus, is a severe threat to Fraxinus excelsior populations across Europe, with spore dispersal playing a critical role in disease progression. While broad-scale environmental drivers of spore dispersal are

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

Water 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.

Influences of Lactate on the High-density Fermentation by Bacillus licheniformis HK

Shipin gongye ke-ji
To improve the biomass and spore rate of Bacillus licheniformis HK, influences of lactate on cell growth and metabolism and spore production were investigated at a 20 L bioreactor, and lactate addition was conducted by coupling with pH7.0 from 16 h to 32
