Recent replication projects in other disciplines have uncovered disturbingly low levels of reproducibility, suggesting that those research literatures may contain unverifiable claims. The conditions contributing to irreproducibility in other disciplines are also present in ecology. These include a large discrepancy between the proportion of "positive" or "significant" results and the average statistical power of empirical research, incomplete reporting of sampling stopping rules and results, journal policies that discourage replication studies, and a prevailing publish-or-perish research culture that encourages questionable research practices. We argue that these conditions constitute sufficient reason to systematically evaluate the reproducibility of the evidence base in ecology and evolution. In some cases, the direct replication of ecological research is difficult because of strong temporal and spatial dependencies, so here, we propose metaresearch projects that will provide proxy measures of reproducibility.

What effect does evolutionary history have on the recovery of multicellularity? Khey and Travisano (2025) show that multicellularity can be recovered in all populations of their experimentally evolved Saccharomyces cerevisiae. However, the history of these cell lines changed the tempo and mode of adaptation in which these lines recovered multicellularity. These findings uncover further details on how evolutionary histories affect future trajectories and contribute another piece to the puzzle that is the predictability of evolution.

Genomes are composed of a mosaic of segments inherited from different ancestors, each separated by past recombination events. Consequently, genealogical relationships among multiple genomes vary spatially across different genomic regions. Genealogical variation among unlinked (uncorrelated) genomic regions is well described for either a single population (coalescent) or multiple structured populations (multispecies coalescent).

Foodborne illness is a critical food safety and public health concern, often resulting from contamination events by resident pathogens in food processing environments (FPEs). , the causative agent of listeriosis, can persist in FPEs over long time periods. Despite rigorous research on the phenotypic and genotypic traits of , no clear pattern has arisen to explain why some strains are able to persist.

Certain pathogenic microorganisms present in nest environments may compromise avian health through direct infection of both adult birds and their offspring, ultimately leading to reduced reproductive success. However, there is a lack of systematic research on the changes in the microbial environment within the nest during the nest-building stages, where nest-building activities may exert a positive impact on the associated microbial communities.

Understanding the spatial distribution pattern of desert plant diversity and its environmental response mechanism is particularly important for the protection of regional biodiversity, and combining phylogenetic information can provide more in-depth insights. To this end, this study conducted a survey of desert plant communities along the southeast to northwest direction of the Hexi Corridor, revealing the variation patterns of species and phylogenetic diversity (PD) indicators along longitude, latitude, and altitude, and explored the driving factors of these patterns in combination with geographical, climatic, and soil factors.
