PeerJ Sections


PeerJ, the journal, is now divided into separate Sections by field.

Section Editors have oversight of their section to ensure the journal maintains a fair peer review process and the highest standards of scientific practice in their fields.

Within each Section, the Academic Editors regularly identify and highlight the most important new PeerJ publications in their field. Learn more & Meet the Section Editors.


The spindle assembly checkpoint and speciation
Ugo Bastolla –– This paper is important in the context of sympatric speciation, where it supports a speciation mechanism based on the variation of the number of chromosomes through sound molecular biology reasoning and mathematical modelling.
Higher carbon sequestration potential and stability for deep soil compared to surface soil regardless of nitrogen addition in a subtropical forest
Biao Zhu –– This study improves our understanding of top vs. deep soil carbon dynamics under carbon substrate addition (i.e. priming effect).
Integrated analysis of lymphocyte infiltration-associated lncRNA for ovarian cancer via TCGA, GTEx and GEO datasets
Walter de Azevedo Jr. –– In this study, Wu et al identified long non-coding RNA-associated competing endogenous RNA (ceRNA) axes that could delineate more reliable prognostic parameters of high-grade serous ovarian cancer, and to examine the long non-coding RNAs’ possible mechanism of in lymphocyte infiltration. The authors were able to define numerous prognostic biomarkers for the incidence and development of high-grade serous ovarian cancer and constructed a network for ceRNA axes.
Understanding PM2.5 concentration and removal efficiency variation in urban forest park—Observation at human breathing height
Kalliat Valsaraj –– The data on particulate matter in an urban forest park site in China may find relevance in many other parts of the developing world
Resampling-based methods for biologists
Andrew Gray –– This is an important and accessible introduction to resampling-based methods that should be of interest to researchers and teachers in a wide range of disciplines, despite its focus on ecological examples.
