Species in the order M.E. Barr ex Minter (, ) develop on a wide range of host plants, but prefer conifers, such as species of and . Conifers, the largest group of gymnosperms, show a high diversity in China. In this study, the species diversity of on twigs of conifers is investigated based on specimens newly collected in China. Morphological characteristics combined with multi-gene phylogenetic analysis (ITS, nrLSU, and mtSSU rDNA) revealed 18 new species, belonging to six new genera (, , , , , and ) and three known genera (, , and ). Additionally, seven new combinations are proposed. The findings underscore the complexity of fungal taxonomy within and the importance of considering multiple criteria for accurate classification. The study also explores the importance of host specificity for genus and species delimitation within the order. A key to genera and species of on twigs of conifers worldwide is provided.

Background: Canola essential oil (CEO) contains linoleic and oleic fatty acids that can inhibit the growth of pathogenic micro-organisms and alter microbial digestion to increase ruminal fermentation and nutrient utilisation.
Objectives: The study evaluated the effect of supplementing a basal goat diet with incremental doses of CEO on chemical constituents and in vitro ruminal fermentation parameters and microbial diversity.
Methods: Experimental treatments were a basal goat diet containing 0.

CRISPR-Cas9 systems have revolutionized biotechnology, creating diverse new opportunities for biomedical research and therapeutic genome and epigenome editing. Despite the abundance of bacterial CRISPR-Cas9 systems, relatively few are effective in human cells, limiting the overall potential of CRISPR technology. To expand the CRISPR-Cas toolbox, we characterized a set of type II CRISPR-Cas9 systems from select bacterial genera and species encoding diverse Cas9s.

The Golfão Maranhense is an extensive estuarine complex that provides nursery grounds and other habitats for several fish species, as well as a wealth of resources for the coastal and estuarine artisanal fisheries of the Maranhão state, in northern Brazil. The present study provides a comprehensive inventory of marine and estuarine teleost fishes of the Golfão Maranhense based on field samplings, analyses of voucher specimens from local collections and literature data. This inventory presents a total of 163 species of teleosts belonging to 107 genera, 57 families and 27 orders.

Fourteen families of Lepidoptera are considered of medical relevance, with six of them recorded in Brazil. However, basic information on medically relevant Lepidoptera in Brazil is limited, with most studies focused on the southern region. This study presents the first comprehensive list of Lepidoptera of medical relevance for the state of Rio de Janeiro based on data from literature, iNaturalist, and the Taxonomic Catalog of the Brazilian Fauna.

Bacilladnaviruses are single-stranded DNA viruses that infect diatoms that, so far, have been primarily identified in marine organisms and environments. Using a viral metagenomics approach, we discovered 13 novel bacilladnaviruses originating from samples of mud-flat snail (; =3 genomes) and benthic sediments (=10 genomes) collected from the Avon-Heathcote Estuary in New Zealand. Comparative genomics and phylogenetic analysis of the new bacilladnavirus sequences in the context of the previously classified members of the family helped refine and further expand the taxonomy.
