Soil Microarthropod Communities Along Salt Marsh Transects of the Wadden Sea Are Predominantly Structured by Niche Differentiation

Ecology and Evolution, Volume 16, Issue 3, March 2026.
We combined α‐ and β‐diversity to investigate the community assembly of soil microarthropods (Collembola, Oribatida, Mesostigmata) along a salt marsh transect from the upper salt marsh to the lower salt marsh to the pioneer zone on three islands in the Wadden Sea of Germany. The results suggest that soil microarthropod communities in the dynamic marine–

Immediate and cumulative effects of nutrient and extreme weather disturbances on pond greenhouse gas emissions

Limnology and Oceanography Letters, Volume 11, Issue 2, March 2026.
Abstract Ponds are significant emitters of greenhouse gases (GHGs). While eutrophication stimulates GHG emissions, responses to nutrient pulses and weather events are less clear. We investigated both immediate and cumulative effects of experimental storm‐scale nutrient pulses, along with unplanned extreme heat and wind events during the experiment, on ...

Genetic Variability and Antibacterial Sensitivity of Dichelobacter nodosus and Fusobacterium necrophorum Infection in Sheep Sulaimani Province, Kurdistan Region, Iraq

The Iraqi Journal of Veterinary Medicine
Footrot is a significant health problem in ruminants, especially sheep, caused by the bacteria Dichelobacter nodosus and Fusobacterium necrophorum. Infected animals may become lame and lose body condition.

Characterization of two putative Dichelobacter nodosus footrot vaccine antigens identifies the first lysozyme inhibitor in the genus

Scientific Reports, 2019
The Gram-negative anaerobic bacterium Dichelobacter nodosus (Dn) causes footrot in ruminants, a debilitating and highly contagious disease that results in necrotic hooves and significant economic losses in agriculture.

Etiological characterization and classification of hoof lesions in sheep from central-western and southwestern Rio Grande do Sul, Brazil (2023-2024) [PDF]

Ciência Rural
: Pododermatitis is prevalent among sheep flocks worldwide, resulting in significant production and economic losses. Dichelobacter nodosus is the main bacterial agent involved in cases of footrot.

Food web complexity alters phytoplankton persistence and resilience to nutrient pulses in experimental ecosystems

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract In aquatic ecosystems, greater food web complexity is theorized to increase persistence and resilience of primary production to pulse disturbances, yet experimental evidence is limited. We simulated two storm‐induced pulse disturbances by adding nutrients (~ 3%–5% increase in ambient concentrations) to three ponds with low, intermediate, and ...

Land use and soil characteristics are associated with increased risk of treponeme‐associated hoof disease in elk

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Environments can shape the occurrence and extent of disease outbreaks in wildlife. We studied the effects of environmental features on the occurrence of treponeme‐associated hoof disease (TAHD), an emerging infectious disease of free‐ranging elk (Cervus canadensis), in southwestern Washington, USA.
