Summary: The Great Ordovician Biodiversification Event reached its peak in the Middle Ordovician in association with climatic cooling and rising atmospheric oxygen levels. Environmental changes in the Yangtze Sea region may offer a new explanation for the decline in invertebrate species during the Middle-Late Ordovician period.

Summary: The respiration rates of marine microbes vary significantly among different prokaryoplankton genera. Minority members of prokaryoplankton perform the majority of respiration, while the most prevalent lineages have extremely low respiration rates. Proteorhodopsin-based phototrophy is likely an important source of energy for prokaryoplankton, indicating a need to reevaluate the mechanistic understanding of the global carbon cycle.

Summary: This study focuses on the enigmatic origin of reddish nodular limestone in the Zitai Formation in South China, indicating that the red coloration may be mainly due to the presence of hematite in oxic bottom seawater, associated with changes in environmental conditions and terrigenous supply.

Summary: When detection is imperfect, ecologists need models to estimate relative abundance. The generalized linear mixed models (GLMMs) and hierarchical N-mixture models are two candidate models. Both models can be viewed as a heuristic framework for relative abundance estimation, and model selection can determine which model predicts observed counts best. In predicting bird counts, both GLMMs and N-mixture models, especially those with beta-binomial detection submodels, are supported in a moderate number of datasets, suggesting their usefulness and context-dependent relative fit.

Summary: A meta-analysis of 46 studies reveals that there are no consistent patterns of difference between artificial and natural substrates, or between eco-friendly and standard concrete, in terms of abundance and richness of colonising biota on built structures. However, there are differences in the abundance of organisms between artificial and natural materials, depending on material type and functional group. Polymer and metal support lower abundances of benthic species compared to biogenic materials and rock, while wood has higher abundances of non-indigenous species. Concrete supports greater abundances of the general community, including habitat-forming species, compared to wood.

Summary: Biodiversity loss is a global ecological crisis that affects various components of human-natural systems. Integrating data from different scientific domains, especially at fine temporal and spatial resolutions, can enhance understanding of species dynamics.

Summary: Fungi and bacteria are the dominant groups of soil microbial communities worldwide. They play a crucial role in regulating carbon cycling by controlling the turnover of soil organic matter. This study provides the first quantitative and high-spatial-resolution map of soil fungal proportion across terrestrial ecosystems, revealing striking latitudinal trends where fungal dominance increases in cold and high-latitude environments. The study also found a strong nonlinear response of fungal dominance to environmental factors, such as mean annual temperature and net primary productivity. These findings have important implications for improving predictions of soil organic matter turnover under current and future climate scenarios.

Summary: This study utilizes a multiproxy dataset to investigate local and global marine paleoredox dynamics during the Middle-Late Ordovician. The results suggest a transition towards more oxygenated marine environments during this time period, coinciding with global climatic cooling trends.

Summary: The frequent invasion of organisms poses a serious threat to biodiversity, ecosystem service functions, and economic development. Invasions from terrestrial systems have been well studied, but invasions from marine systems still lack a literature review, especially for invasive algae.

Summary: The study found that later developed stages of biocrusts exhibited higher values of ecosystem multifunctionality indices, while the diversity of 16S rRNA gene decreased with succession. The increasing relative abundance of non-cyanobacterial photosynthetic organisms was identified as the key predictor driving ecosystem multifunctionality indices during biocrust succession.

Summary: Contrary to the expectation of neutral theory, the abundance or rarity of species in the fossil record does not predict their longevity in ocean ecosystems. Limited empirical studies have shown that species with low abundances are not necessarily more prone to extinction.

Summary: The study found that the use of environmental DNA (eDNA) metabarcoding can accurately assess the composition and spatial distribution of freshwater fish communities. In a transplant experiment in the St. Lawrence River, the eDNA of brown trout was detected at five locations up to 5,000 meters from the cage, but only one sampling location downstream from the cage showed a significant impact on community composition. Cluster analysis confirmed the impact of the brown trout eDNA on community composition, separating this location from others. No evidence of transport effect of brown trout eDNA on fish community composition was observed in other sampling locations.

Summary: Plant interactions belowground are important and difficult to quantify accurately. The msGBS method presented in this study allows for high taxonomic resolution and parallel quantification of multiple species in root samples. Compared to qPCR, msGBS offers similar results with advantages in revealing hidden belowground interactions.

Summary: This study explored an enhanced quantitative approach by metabarcoding whole zooplankton communities, revealing a higher species richness compared to traditional morphological processing, especially in the meroplankton fraction. There was a strong quantitative relationship between sequence counts and relative biomass within taxa detected by both metabarcoding and microscopy, with crustaceans showing the highest correlations.

Summary: This research aims to investigate the knowledge of pre-service preschool teachers about vertebrate animals. The results indicate a lack of knowledge about the local fauna, which can hinder its teaching and conservation. Therefore, training actions are needed to provide knowledge of local biodiversity and promote biodiversity conservation in schools.
