Enhancing species discovery and description in algal turfs: A case study in the green alga Pseudoderbesia (Bryopsidales)

open access: yesJournal of Phycology, EarlyView.
Abstract Algal turfs are assemblages consisting of small marine green, brown, and red algae on the scale of millimeters to a few centimeters. Due to their small size, they have been less intensively studied by macroalgal taxonomists, and they also fall outside the scope of microalgal taxonomists, who tend to focus on smaller, often unicellular, taxa ...

The Role of Viruses in the Pathogenesis of Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
This narrative review aimed to summarize current evidence on the presence and potential pathogenic role of viruses in periodontitis. Design: Narrative Review; Population: Patients with periodontitis; Exposure: Detection of viruses in oral samples (biopsies, saliva, gingival crevicular fluid, subgingival plaque, blood); Outcome: Viral prevalence, load ...

Hidden lineages in the African Sky Islands: A taxonomic reevaluation of Afrocarduus (Compositae)

open access: yesJournal of Systematics and Evolution, EarlyView.
Species delimitation is crucial for biodiversity studies. Using Hyb‐Seq and phylogenomics, we reassessed Afrocarduus, endemic to Afromontane and Afroalpine regions, uncovering 16 evolutionary lineages (2.3 Mya). Morphological data support their distinctiveness, with acaulescence evolving independently twice. The traditionally broad A.

Integrative taxonomy supports DNA barcoding in revealing an abundant cryptic species in the United States Coastal Plain

open access: yesJournal of Systematics and Evolution, EarlyView.
We present the most densely sampled phylogeny of Carex section Lupulinae to date (107 specimens) and describe herein a new cryptic species for science from the southern United States, which is locally abundant and found in well‐explored and densely populated areas. Combining DNA sequences with morphometric data obtained from 299 samples, we Demonstrate

Multiplex nested PCR for Brazilian Alphavirus diagnosis

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2004
A reverse-transcriptase PCR (RT-PCR) and a multiplex nested PCR were developed for the rapid detection and identification of 14 Brazilian alphaviruses. Using Alphavirus genus-specific primers in a RT-PCR, we obtained amplified products of 434 bp. Species-specific primers were selected and simultaneously tested in a multiplex nested PCR.
