Model microbial communities are regularly used to test ecological and evolutionary theory as they are easy to manipulate and have fast generation times, allowing for large-scale, high-throughput experiments. A key assumption for most model microbial communities is that they stably coexist, but this is rarely tested experimentally. Here we report the (dis)assembly of a five-species microbial community from a metacommunity of soil microbes that can be used for future experiments. Using reciprocal invasion-from-rare experiments we show that all species can coexist and we demonstrate that the community is stable for a long time (~600 generations). Crucially for future work, we show that each species can be identified by their plate morphologies, even after >1 year in co-culture. We characterise pairwise species interactions and produce high-quality reference genomes for each species. This stable five-species community can be used to test key questions in microbial ecology and evolution.

Understanding the molecular characteristics and metabolic processes of the mammalian endometrium is crucial for advancing biological research, particularly in veterinary obstetrics and pathology. This study established and analyzed organoids from the endometrial epithelial stem cells of five mammals with different placental types: cows (cotyledonary), dogs and cats (zonary), pigs (diffuse), and rats (discoid). The organoids from these five species were maintained for over 13 passages, successfully frozen-thawed, and confirmed by pathological analysis to retain the characteristics of the original tissues.

Previous studies have shown that at least six genera of the Cheilanthoideae, a subfamily of the fern family Pteridaceae, may not be monophyletic. In these non-monophyletic genera, the Old-World genus Paragymnopteris including approximately five species have long been controversial. In this study, with an extensive taxon sampling of Paragymnopteris, we assembled 19 complete plastomes of all recognized Paragymnopteris species, plastomes of Pellaea (3 species) and Argyrochosma (1 species), as well as transcriptomes from Paragymnopteris (6 species) and Argyrochosma (1 species).

Article Synopsis
- The study focuses on five species of Phortica flies in Europe and the Middle East, particularly Phortica variegata and Phortica okadai, known as vectors for the zoonotic eyeworm Thelazia callipaeda, in a region near Rome, Italy.
- Over three years (2018-2020), researchers collected and identified nearly 5,600 flies, revealing a dominance of Phortica variegata, which was found to be infected with T. callipaeda, while Phortica oldenbergi showed differing behavior in fruit traps.
- Environmental factors like temperature, wind speed, and pressure influenced the population dynamics of these species, with the study being the first to explore these ecological interactions

This study aims to evaluate the in silico genomic characteristics of five species of the genus : , , , , and , with a view to their application in therapeutic research. The 16S rRNA comparison indicated that these species were phylogenetically distinct. Pairwise comparisons of digital DNA-DNA hybridization (dDDH) and OrthoANI values between these studied type strains indicated that dDDH values were below 62.
