Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Are DSM‐5 and ICD‐11 posttraumatic stress disorder measures assessing the same construct? Evidence from a Rasch‐based analysis

open access: yesJournal of Traumatic Stress, EarlyView.
Abstract This study examined whether DSM‐5 and ICD‐11 self‐report operationalizations of posttraumatic stress disorder (PTSD) are psychometrically equivalent. Using Rasch modeling, we compared the psychometric properties and convergent validity of the PTSD Checklist for DSM‐5 (PCL‐5) and the International Trauma Questionnaire (ITQ) in a sample of 483 ...

Area‐restricted search under realistic constraints

open access: yesOikos, EarlyView.
Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...
