Plastid and nuclear phylogenomics of Cyphostemma (Vitaceae) provide new insights into genome size evolution across sub‐Saharan Africa

open access: yesJournal of Integrative Plant Biology, EarlyView.
Some African Cyphostemma species evolved much larger genomes as they adapted to dry, rocky habitats. These expansions are linked to succulent traits and specialization on nutrient‐rich limestone outcrops. The findings show how climate‐driven aridification shaped plant evolution and highlight broader genome‐environment patterns across flowering plants ...

The effect of a multispecies probiotic on the composition of the faecal microbiota and bowel habits in chronic obstructive pulmonary disease patients treated with antibiotics [PDF]

open access: yes, 2009
Short-term antibiotic treatment profoundly affects the intestinal microbiota, which may lead to sustained changes in microbiota composition. Probiotics may restore such a disturbance.

Patterns of Composition, Richness and Endemicity of Cyperaceae Across Open and Closed Habitats in Madagascar's Central Highlands

open access: yesBiotropica, Volume 58, Issue 2, March 2026.
We assessed Cyperaceae species composition, richness and endemicity across closed (forest), dry open (dry grasslands, rocky outcrops, bare dry soils), and wet open (marshes, swamps, wet grasslands, riparian areas) habitats in Isalo National Park and the Itremo Massif Protected Area, both in Madagascar's Central Highlands.

Evaluating primers for profiling anaerobic ammonia oxidizing bacteria within freshwater environments. [PDF]

open access: yesPLoS ONE, 2013
Anaerobic ammonia oxidizing (anammox) bacteria play an important role in transforming ammonium to nitrogen gas and contribute to fixed nitrogen losses in freshwater environments.

Microbial Communities of Hydrothermal Guaymas Basin Surficial Sediment Profiled at 2 Millimeter-Scale Resolution

open access: yesFrontiers in Microbiology, 2021
The surficial hydrothermal sediments of Guaymas Basin harbor complex microbial communities where oxidative and reductive nitrogen, sulfur, and carbon-cycling populations and processes overlap and coexist.

Relapsing–Remitting Multiple Sclerosis Is Associated With a Dysbiotic Oral Microbiome

open access: yesAnnals of Clinical and Translational Neurology, Volume 13, Issue 2, Page 256-269, February 2026.
ABSTRACT Objective Multiple sclerosis (MS) is a chronic autoimmune disorder characterized by inflammation, demyelination, and neurological impairment. While the gut microbiota's role in MS is extensively studied, the association between the oral microbiota and MS remains underexplored, particularly in North American cohorts.

Changes in proteolytic bacteria in paddy soils in response to organic management

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
Proteolytic bacterial communities, which mineralize organic nitrogen, play a key role in agricultural systems. In this study, alkaline metalloprotease (apr) gene fragments from proteolytic bacteria were investigated in bulk and rhizosphere paddy soil ...

Fluorescence in situ hybridisation detection of Lactobacillus plantarum group on olives to be used in natural fermentations [PDF]

open access: yes, 2006
At present there are very few studies on the bacterial diversity of olives and on the importance of the microbial species for the fermentation of olives aimed to table olives production.

Global insular leaf size shifts follow the island rule, independently of insect herbivory and macroclimate

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
We found a positive, non‐linear, saturating relationship between mainland and island leaf sizes, reflecting an island rule‐like pattern. Small‐leaved mainland species tend to develop larger leaves on islands, while this effect weakens for larger‐leaved species, a pattern consistent across both conspecific and congeneric comparisons. Abstract The island
