Diversity of the Germination Apparatus in Clostridium botulinum Groups I, II, III and IV

open access: yesFrontiers in Microbiology, 2016
Clostridium botulinum is a highly dangerous pathogen that forms very resistant endospores that are ubiquitous in the environment, and which, under favourable conditions germinate to produce vegetative cells that multiply and form the exceptionally potent

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

open access: yesBiological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Explosive spore dispersal of Selaginella kraussiana

open access: yes
Videos showing the explosive spore dispersal of the reproductive structures (strobili) in the lycophyte Selaginella kraussiana. In several instances in this dataset, microsporangia under desiccating conditions can be seen to firstly dehisce, exposing the

Long-distance spore dispersal in wood-inhabiting Basidiomycetes [PDF]

open access: yes, 2001
Eight species of wood-inhabiting basidiomycetes (Laurilia sulcata, Peniophora aurantiaca, Resinicium bicolor, Scytinostroma galactinum, Terana caerulea, Trichaptum abietinum, T. biforme and T.

Acoustic‐driven surface cleaning with millimeter‐sized bubbles at translational resonance

open access: yesDroplet, EarlyView.
Time‐lapse visualization comparing bubble trajectories. The top panel (0 Hz) shows a bubble's linear path under no acoustic forcing, while the bottom panel (50 Hz) demonstrates the oscillatory motion induced by acoustic waves at a resonance mode. This mechanism holds promising potential for applications such as surface cleaning.

Establishment of Heterobasidion annosum s.l. infections in young Norway spruce dominated stands [PDF]

open access: yes, 2013
One of the worst pathogens on Norway spruce, Heterobasidion annosum s.l., can establish in previously healthy trees by spores landing on freshly made stumps from where mycelia can grow via root grafts and contacts to the adjacent tree.

Large droplet release

open access: yesDroplet, EarlyView.
Curved hydrophobic mesh surfaces enable stable release of large droplets exceeding the capillary length. By tuning surface curvature, porosity, and acceleration, oscillatory breakup is suppressed, producing near‐spherical droplets ideal for high‐precision fluid applications and multiphase flow control.

Scale‐dependent assembly shapes taxon‐dependent responses of soil microbes to island isolation and area

open access: yesEcography, EarlyView.
The theory of island biogeography (TIB) remains contentious for microbes, as their immense dispersal potential and microscopic size may decouple diversity from classic isolation/area effects. We explicitly tested TIB scaling rules for soil bacteria and fungi across 20 oceanic islands using a rigorous multi‐scale framework that integrated high ...

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...

Antibody kinetics against tetanus toxoid before and after primary vaccination of foals

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Vaccination recommendations for foals against Clostridium tetani vary. Available studies assessing foal immune responses, maternal antibody interference, or individual variation often used small foal numbers. Objectives To quantify antibody responses after tetanus vaccination in foals and explore associations with passively ...
