Museo Nacional de Ciencias Naturales (CSIC), Departamento de Biodiversidad y Biología Evolutiva, C/ José Gutiérrez Abascal 2, ES-28006 Madrid, Spain..

The monophyly and taxonomic validity of some currently accepted genera of gall wasps in the Cynipini (Hymenoptera: Cynipidae) are being challenged by recent systematic studies. Here we used morphological and molecular data to re-describe and revise the taxonomic limits of the monotypic genus Kokkocynips Pujade-Villar Melika, previously recorded only from Mexico.                We describe a new species from Panama, Kokkocynips panamensis Medianero Nieves-Aldrey, reared from galls on Quercus salicifolia Neé, and add new records from Mexico for the type species of the genus K.

A revision of the Pontocaspian gastropods of the subfamily Caspiinae (Caenogastropoda: Hydrobiidae).

Zootaxa 2021 Feb 19;4933(2):zootaxa.4933.2.1. Epub 2021 Feb 19.

Department of Invertebrate Fauna and Systematics, Schmalhausen Institute of Zoology, National Academy of Sciences of Ukraine, B. Khmelnytsky Str. 15, 01030 Kiev, Ukraine..

The Caspiinae comprise small gastropod species inhabiting low-salinity environments of the Pontocaspian region, specifically the Caspian Sea and the limans, estuaries and lower river reaches of the northern Black Sea Basin. There is considerable discrepancy in the literature as to which taxa are attributed to this hydrobiid subfamily, which of them are valid and what rank they have. Moreover, the generic classification is not agreed upon. Read More

Farlow Reference Library and Herbarium of Cryptogamic Botany, Harvard University, 22 Divinity Avenue, Cambridge, MA, 02138, USA.

Since its resurrection, the resinicolous discomycete genus Sarea has been accepted as containing two species, one with black apothecia and pycnidia, and one with orange. We investigate this hypothesis using three ribosomal (nuITS, nuLSU, mtSSU) regions from and morphological examination of 70 specimens collected primarily in Europe and North America. The results of our analyses support separation of the traditional Sarea difformis s. Read More

Non-ammocoete larvae of Palaeozoic stem lampreys.

Nature 2021 Mar 10;591(7850):408-412. Epub 2021 Mar 10.

Department of Organismal Biology and Anatomy, University of Chicago, Chicago, IL, USA.

Ammocoetes-the filter-feeding larvae of modern lampreys-have long influenced hypotheses of vertebrate ancestry. The life history of modern lampreys, which develop from a superficially amphioxus-like ammocoete to a specialized predatory adult, appears to recapitulate widely accepted scenarios of vertebrate origin. However, no direct evidence has validated the evolutionary antiquity of ammocoetes, and their status as models of primitive vertebrate anatomy is uncertain. Read More

Names of phytopathogenic fungi: a practical guide.

Phytopathology 2021 Jan 24. Epub 2021 Jan 24.

USDA-ARS Beltsville Agricultural Research Center, 57604, Mycology & Nematology Genetic Diversity & Biology Laboratory, Beltsville, Maryland, United States;

Names of phytopathogenic fungi and oomycetes are essential to communicate knowledge about species and their biology, control, and quarantine as well as for trade and research purposes. Many plant pathogenic fungi are pleomorphic, meaning that they produce different asexual (anamorph) and sexual (teleomorph) morphs in their lifecycles. Because of this, more than one name has been applied to different morphs of the same species, which has confused users of names. Read More

GEOMAR Centre for Marine Biotechnology (GEOMAR-Biotech), Research Unit Marine Natural Products Chemistry, GEOMAR Helmholtz Centre for Ocean Research Kiel, Am Kiel-Kanal 44, 24106 Kiel, Germany.

It is widely accepted that the commensal gut microbiota contributes to the health and well-being of its host. The solitary tunicate emerges as a model organism for studying host-microbe interactions taking place in the gut, however, the potential of its gut-associated microbiota for marine biodiscovery remains unexploited. In this study, we set out to investigate the diversity, chemical space, and pharmacological potential of the gut-associated microbiota of collected from the Baltic and North Seas. Read More

Escola de Ciências da Saúde e da Vida, Pontifícia Universidade Católica do Rio Grande do Sul, 90619-900 Porto Alegre, RS, Brazil.

The phylogeny and systematics of fur seals and sea lions (Otariidae) have long been studied with diverse data types, including an increasing amount of molecular data. However, only a few phylogenetic relationships have reached acceptance because of strong gene-tree species tree discordance. Divergence times estimates in the group also vary largely between studies.

Based on molecular phylogenetic analyses of a multigene matrix of partial nuSSU-ITS-LSU rDNA, , and sequences and by morphological evidence, the genus is shown to be the closest relative of , and confirmed to be a member of the Cenangiaceae (Leotiomycetes). While and share many traits like similar conidia, conidiogenesis, asci and ascospores, their apothecia differ particularly in excipular features and are therefore recognized as distinct genera. , described from North America, is excluded from the genus but shown to represent the sexual morph of the European , and it is therefore synonymized with the latter.

Morphological and phylogenetic data do not support the split of Alexandrium into four genera.

Harmful Algae 2020 09 18;98:101902. Epub 2020 Sep 18.

Climate Change Cluster, University of Technology Sydney, Ultimo, NSW 2007, Australia.

A recently published study analyzed the phylogenetic relationship between the genera Centrodinium and Alexandrium, confirming an earlier publication showing the genus Alexandrium as paraphyletic. This most recent manuscript retained the genus Alexandrium, introduced a new genus Episemicolon, resurrected two genera, Gessnerium and Protogonyaulax, and stated that: "The polyphyly [sic] of Alexandrium is solved with the split into four genera". However, these reintroduced taxa were not based on monophyletic groups. Read More

It is generally accepted that postpartum uterine infections decrease conception rates in dairy cows. Whereas clinical endometritis (CE) has been studied intensively, only little information about CE at the time of artificial insemination (AI) is available. The aim of this study was to characterize the intrauterine cultivable aerobic microbiota in healthy cows and in cows with mild CE at AI and to investigate its effect on the subsequent insemination success.

Dietary cellulose induces anti-inflammatory immunity and transcriptional programs via maturation of the intestinal microbiota.

Gut Microbes 2020 11;12(1):1-17

Institute for Medical Microbiology and Hospital Hygiene, Philipps University , Marburg, Germany.

Although it is generally accepted that dietary fiber is health promoting, the underlying immunological and molecular mechanisms are not well defined, especially with respect to cellulose, the most ubiquitous dietary fiber. Here, the impact of dietary cellulose on intestinal microbiota, immune responses and gene expression in health and disease was examined. Lack of dietary cellulose disrupted the age-related diversification of the intestinal microbiota, which subsequently remained in an immature state. Read More

Evaluating method and potential risks of chlorine-resistant bacteria (CRB): A review.

Water Res 2021 Jan 28;188:116474. Epub 2020 Sep 28.

Chlorine-resistant bacteria (CRB) are commonly defined as bacteria with high resistance to chlorine disinfection or bacteria which can survive or even regrow in the residual chlorine. Chlorine disinfection cannot completely control the risks of CRB, such as risks of pathogenicity, antibiotic resistance and microbial growth. Currently, researchers pay more attention to CRB with pathogenicity or antibiotic resistance. Read More

A brief history of the species concept in virology and an opinion on the proposal to introduce Linnaean binomial virus species names.

Arch Virol 2020 Dec;165(12):3073-3077

Medical University of Vienna, Vienna, Austria.

The species concept used in virology is based on the logic of the Linnaean hierarchy, which views a species class as the lowest abstract category that is included in all the higher categories in the classification, such as genera and families. As a result of this class inclusion, the members of a species class are always less numerous than the members of higher classes, which become more numerous as one moves up in the hierarchy. Because species classes always have fewer members than any of the higher classes, logic requires that they need more qualifications for establishing membership than any of the higher classes.
