  The authors propose that positive biodiversity-ecosystem functioning relationships found in experiments have been exaggerated because commonly used statistical analyses are flawed. To remedy this, a new type of analysis based on a concept of "partial density monoculture yield" is proposed. However, the presented concept and analysis methods are not reproducibly described (how can partial density monoculture yield experimentally be assessed?), do not appear to be complete, and are inadequate for hypothesis testing. The reviewers found that the authors misinterpret current research in the field and made limited efforts to understand or address the reviewer comments about this study.

  This study makes a valuable advance in our understanding of defensive symbionts in insects. It uses a meta-analysis to quantify the magnitude of change in host fitness components when symbionts are present in hosts exposed to natural enemies. The evidence supporting the study conclusions is solid, with analyses confirming common assumptions that symbionts generally provide defence at low cost to hosts.

  The authors propose a new methodology to survey insects, using new sensors and analytical capabilities that could be valuable for addressing urgent conservation challenges. While the results of the optical sensors appear to be comparable to those obtained with classical survey methodologies, current analyses are considered incomplete.

  This fundamental study substantially advances our understanding of how habitat fragmentation and climate change jointly influence bird community thermophilization in a fragmented island system. The authors provide convincing evidence using appropriate and validated methodologies to examine how island area and isolation affect the colonization of warm-adapted species and the extinction of cold-adapted species. This study is of high interest to ecologists and conservation biologists, as it provides insight into how ecosystems and communities respond to climate change.

  This article presents valuable findings on the impact of climate change on odonates, integrating phenological and range shifts to broaden our understanding of biodiversity change. The study leverages extensive natural history data, offering a combined analysis of temporal trends in phenology and distribution and their potential drivers. The support for the findings is solid, though additional clarification regarding the methods and alternative sensitivity analyses could make the conclusions stronger.

  This important study reports that the neurohormone, bursicon, and its receptor, play a role in the seasonal polyphenism of the bug Cacopsylla chinensis. Low temperature activates the bursicon signaling pathway during the transition from the summer to the winter form, affecting cuticle pigment and thickness as well as chitin content. The solid experiments reveal how bursicon signaling, which is modulated by the microRNA miR-6012, regulates features of polyphenism related to the exoskeleton, although it is less clear what the upstream regulatory events are.
