Journal impact factors were devised to qualify and compare university library holdings but are frequently repurposed for use in ranking applications, research papers, and even individual applicants in mycology and beyond. The widely held assumption that mycological studies published in journals with high impact factors add more to systematic mycology than studies published in journals without high impact factors nevertheless lacks evidential underpinning. The present study uses the species hypothesis system of the UNITE database for molecular identification of fungi and other eukaryotes to trace the publication history and impact factor of sequences uncovering new fungal species hypotheses.

Today, research on the diversity of eukaryotes in global ecosystems heavily relies on nuclear ribosomal RNA (rRNA) markers. Here, we present the research community-curated reference database EUKARYOME for nuclear ribosomal 18S rRNA, internal transcribed spacer (ITS) and 28S rRNA markers for all eukaryotes, including metazoans (animals), protists, fungi and plants.

By utilizing composite soil samples, we identified the predictors that drive partner specificity in both plants and fungi, with a particular focus on ectomycorrhizal associations. Fungal guilds exhibited significant differences in overall partner preference and avoidance, richness, and specificity to specific tree genera.

- Tropical ecosystems pose challenges for Galapagos sea lions due to variable food sources, leading researchers to investigate their dietary adaptability through DNA-metabarcoding of scat samples from five rookeries.
- The study identified 98 different prey types, including bony fish, sharks, rays, and deep-sea fish, supporting the idea that Galapagos sea lions exhibit trophic flexibility by consuming various prey from different habitats.
- Significant differences in diet were found between rookeries, with Punta Pitt focusing on deeper, high-trophic-level species, while Santa Fe consumed more shallow, planktivorous fish, showcasing how local factors influence dietary choices.
Article Synopsis
- The study provides transcriptomic data for two asexual non-marine species of Ostracoda, a group of small crustaceans, contributing new reference transcriptomes and single-specimen data.
- Gene expression was analyzed across four developmental stages, showing that eggs and small larvae are similar, while adults are distinct but closer to larger larvae.
- The research demonstrates that reliable transcriptomic data can be obtained from single specimens, including eggs, highlighting the potential for studying small metazoans.
