Functional traits mediate individualistic species‐environment distributions at broad spatial scales while fine‐scale species associations remain unpredictable

American Journal of Botany, Volume 109, Issue 12, Page 1991-2005, December 2022., 2022
Abstract Premise Numerous processes influence plant distributions and co‐occurrence patterns, including ecological sorting, limiting similarity, and stochastic effects. To discriminate among these processes and determine the spatial scales at which they operate, we investigated how functional traits and phylogenetic relatedness influence the ...

Phylodynamic pattern of genetic clusters, paradigm shift on spatio-temporal distribution of clades, and impact of spike glycoprotein mutations of SARS-CoV-2 isolates from India

Journal of Global Infectious Diseases, 2021
Introduction: The COVID-19 pandemic is associated with high morbidity and mortality, with the emergence of numerous variants. The dynamics of SARS-CoV-2 with respect to clade distribution is uneven, unpredictable and fast changing.

“Cladus” and clade: a taxonomic odyssey [PDF]

Theory in Biosciences, 2020
The fate of "clade," both as concept and word, is reconstructed here beginning with its first appearance in 1866 as "Cladus," in Haeckel's Generelle Morphologie, continuing up to the present. Although central to phylogenetics, the concept of clade is paradoxical since it has been ambiguously understood or even misunderstood by its own promoters ...

The relationship between chlorophyllous spores and mycorrhizal associations in ferns: evidence from an evolutionary approach

American Journal of Botany, Volume 109, Issue 12, Page 2068-2081, December 2022., 2022
Abstract Premise Approximately 14% of all fern species have physiologically active chlorophyllous spores that are much more short‐lived than the more common and dormant achlorophyllous spores. Most chlorophyllous‐spored species (70%) are epiphytes and account for almost 37% of all epiphytic ferns.

Distribution and functional analyses of mutations in spike protein and phylogenic diversity of SARS-CoV-2 variants emerged during the year 2021 in India

Journal of Global Infectious Diseases, 2023
Introduction: Prolonged COVID-19 pandemic accelerates the emergence and transmissibility of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) variants through the accumulation of adaptive mutations.

Candida albicansclades [PDF]

FEMS Immunology & Medical Microbiology, 2003
DNA fingerprinting with the complex probe Ca3 has revealed the following five Candida albicans clades: group I, group II, group III, group SA and group E. These groups exhibit geographical specificity. Group SA is relatively specific (i.e., highly enriched) to South Africa, group E is relatively specific to Europe, and group II is absent in the ...

Dirofilaria immitis in Bulgaria: the first genetic baseline data and an overview of the current status

Helminthologia, 2020
Dirofilaria immitis, the agent of canine dirofilariosis, is a common parasite of domestic and wild carnivores with zoonotic potential and worldwide distribution, being endemic in many countries.

Characterization of community-acquired Clostridioides difficile strains in Israel, 2020–2022

Frontiers in Microbiology, 2023
BackgroundThe prevalence of community-acquired Clostridioides difficile infection (CA-CDI) has been rising, due to changes in antibiotics prescribing practices, emergence of hypervirulent strains and improved diagnostics.

An emergent clade of SARS-CoV-2 linked to returned travellers from Iran

bioRxiv, 2020
The SARS-CoV-2 epidemic has rapidly spread outside China with major outbreaks occurring in Italy, South Korea and Iran. Phylogenetic analyses of whole genome sequencing data identified a distinct SARS-CoV-2 clade linked to travellers returning from Iran ...

Patients with treated indolent lymphomas immunized with BNT162b2 have reduced anti‐spike neutralizing IgG to SARS‐CoV‐2 variants, but preserved antigen‐specific T cell responses

American Journal of Hematology, Volume 98, Issue 1, Page 131-139, January 2023., 2023
Abstract Patients with indolent lymphoma undertaking recurrent or continuous B cell suppression are at risk of severe COVID‐19. Patients and healthy controls (HC; N = 13) received two doses of BNT162b2: follicular lymphoma (FL; N = 35) who were treatment naïve (TN; N = 11) or received immunochemotherapy (ICT; N = 23) and Waldenström's macroglobulinemia
