Soil Metabarcoding Helps Identify Recalcitrant Taxa From Chaparral Seed Banks

Journal of Vegetation Science, Volume 37, Issue 2, March/April 2026.
Soil seed banks preserve plant diversity, but traditional germination methods often miss dormant or hard‐to‐germinate species. Our study tested metabarcoding as an alternative, finding that DNA‐based sequencing was more reliable than RNA and that water treatments influenced sequencing results.

Dominant Species Drive Biomass and Diversity Responses to Nutrient Inputs

Ecology and Evolution, Volume 16, Issue 2, February 2026.
In a mesic grassland co‐limited by nitrogen and phosphorus, responses in plant community diversity and particularly of dominant species do not always correspond to responses in aboveground net primary productivity and functional group biomass production.

Brucella melitensis and B. abortus in eggs, larvae and engorged females of Dermacentor marginatus

Ticks and Tick-borne Diseases, 2018
Brucellosis is a relatively common zoonosis, particularly in the developing countries. Our aim was to cultivate the Brucella wild-type strain from eggs of Dermacentor marginatus, and to molecularly investigate the presence of Brucella DNA in different developmental stages. A total of 350 engorged adult female ticks were collected from sheep and cattle,

Temporal and spatial heterogeneity in dispersal and demography of a long‐lived philopatric seabird

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract Individuals make habitat selection decisions at different moments of their life and in heterogeneous habitats. Understanding the links between environmental changes and demographic patterns during the individuals' life is therefore critical to predict long‐term eco‐evolutionary dynamics and species persistence. However, fitness and persistence

Liposomal delivery of p-ialB and p-omp25 DNA vaccines improves immunogenicity but fails to provide full protection against B. melitensis challenge

Genetic Vaccines and Therapy, 2010
BackgroundWe have previously demonstrated protective efficacy against B. melitensis using formulations of naked DNA vaccines encoding genes ialB and omp25.

Insights Into Sequences of Viral and Bacterial Origin in the Metatranscriptome of Centaurea cyanus L. Susceptible and Resistant to Acetolactate Synthase (ALS)‐Inhibiting Herbicides

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Metatranscriptomic analysis of Centaurea cyanus revealed diverse plant‐associated viral and bacterial sequences in herbicide‐susceptible and ‐resistant biotypes. While novel partitiviruses occurred independently of resistance status, differences in bacterial community composition may suggest a potential role of the plant microbiome in responses to ...

Biological corridors are crucial habitat features that boost biodiversity in agroecological systems of Argentina

Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.
Our work shows for the first time in the region that biological corridors increase biodiversity and promote interactions between different components of the production system, using a methodology never before used in Argentina such as the Griffon index.

Towards Integrated Surveillance of Marine Brucellosis: Diagnostic and Phylogenetic Assessment of Brucella ceti in Stranded Dolphins of the Western Mediterranean Sea

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Reports of brucellosis in free‐ranging cetaceans are increasing worldwide, particularly in the Mediterranean Sea. To enhance diagnostic accuracy and epidemiological understanding of cetacean brucellosis in the Western Mediterranean Sea, we analyzed bacteriological, serological, and molecular data from 30 cetaceans belonging to three different species ...

Comparative Proteomics Analyses Reveal the virB of B. melitensis Affects Expression of Intracellular Survival Related Proteins

PLoS ONE, 2009
Backgound Brucella melitensis is a facultative, intracellular, pathogenic bacterium that replicates within macrophages. The type IV secretion system encoded by the virB operon (virB) is involved in Brucella intracellular survival. However, the underlying

Brucella abortus Inhibits SIRT1 to Modulate Intracellular Survival and Autophagy in Macrophages

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Brucella spp., the causative agents of brucellosis, are facultative intracellular pathogens lacking classical virulence factors, and the disease represents one of the most prevalent zoonoses worldwide. Nevertheless, Brucella efficiently modulates the expression of genes associated with host cellular metabolism and immune evasion. The SIRT1 protein is a
