Summary: The present study failed to replicate the astonishing concept of conflict priming reported in previous work and does not open the doors for a new window on sequences of conflicts. Nevertheless, the failed replication is valuable for future research, since it demonstrated that Conflict Priming as a facilitation of processing of conflict trials following deviant tones, is not a confirmed finding.

Summary: This paper discusses a novel method of assessing complementarity between three variable energy sources using correlation, compromise programming, and normalization. The method calculates a complementarity index which is applied to a case study in Poland. However, the normalization of the index overestimates the complementarity potential, which is discussed in detail, and an alternative way of calculating the index is proposed to eliminate this issue.

Summary: In their review, Abbot-Smith et al. argue for the importance of whole-classroom, tier-1 intervention approaches in developing conversational skills during the preschool and primary grades. We provide commentary discussing the benefits and challenges of classroom conversation, specifically during the school transition period (ages 2-6), and suggest potential strategies for teachers to foster more conversation with young children.

Summary: The debate over the focus of classroom instructional time continues among educators, policy makers, academics, and health professionals. This commentary emphasizes the importance of prioritizing children's biologically secondary skills, such as reading, writing, and spelling, and advises against dedicating primary classroom time to conversational skills due to limited research evidence. An alternative model for incorporating conversational skills into classroom practice, through the use of Multi-Tiered Systems of Support and Response to Intervention, is proposed.

Summary: In this study, the microsporidian Enterocytozoon hepatopenaei from Penaeus vannamei was redescribed based on spore morphology, life cycle, pathology, and molecular character. New features were discovered compared to Enterocytozoon hepatopenaei isolated from Penaeus monodon. Phylogenetic analysis showed a common ancestor for all Enterocytozoon hepatopenaei isolates.

Summary: The study found that around 17 years old is a critical period for the most effective acquisition of a second language, with the late childhood to late adolescence age range being crucial for learning an L2. The results can be conceptualized by emergentist models of language acquisition where behavior and brain interactively reorganize across development.

Summary: This commentary endorses the call for social conversation skills training and raises challenges in designing such efforts. The challenges include identifying universally important conversational skills, considering cultural variability, and determining meaningful outcomes and assessment methods. The commentary discusses Social Problem-solving Skills Training, cultural variability in children's conversational behavior, and governmental standards for students' conversational competence.

Summary: Delay discounting, a widely studied phenomenon in psychology, has recently been proposed as a transdiagnostic variable. Two recently published articles provide stimulating perspectives but also raise issues for further discussion. This article critically evaluates the publications, offers alternative interpretations, and proposes future research directions to enhance theoretical models.

Summary: Social tolerance is believed to promote cooperation in various species, but studies on bonobos and chimpanzees have yielded conflicting results. This study aimed to replicate a previous experiment to shed light on these discrepancies. The findings showed that bonobos and chimpanzees displayed similar levels of co-feeding, indicating similar tolerance. However, bonobos exhibited greater cooperation than chimpanzees when the food was monopolizable, supporting the original study's findings. These results challenge the interpretation that bonobos cooperate more because they are inherently more tolerant at the species level.

Summary: Van der Werff et al. (2014b) proposed that recalling diverse types of pro-environmental behavior strengthens environmental self-identity by invoking internal attribution. We attempted to replicate the study with improved statistical power and found that heterogeneous recall had a weak but significant effect on strengthening environmental self-identity. By using structural equation modeling, we discovered that this effect was driven by normative social influence rather than internal attribution, which has implications for promoting sustainable consumption.

Summary: Compound-specific stable isotope analysis (CSIA) is a powerful tool for understanding trophic transfer of dietary molecules. A new online high-capacity gas chromatography-isotope ratio mass spectrometry technique (H-2-CSIA) accurately determines delta H-2 values for fatty acids in aquatic food webs. Lipid extracts from aquatic sources have distinctive delta H-2 values useful for assessing sources, trophic interactions, and dietary origin of fatty acids in consumer tissue.

Summary: Stable isotope analyses of environmental waters, including δH-2, δO-18, and δO-17, are crucial in understanding hydrology and environmental research. Most laboratories produced acceptable results for δO-18 and δH-2, but some struggled to replicate their claimed precision. Analysis of Delta O-17 showed varied results between IRMS and laser spectrometry, with many labs unable to achieve the claimed precision level.

Summary: This study investigates the metabolism of LC-PUFA in freshwater zooplankton and finds that zooplankton can compensate for low dietary EPA supply by activating LC-PUFA biosynthesis. It also shows that herbivorous zooplankton play a crucial role in upgrading FA for higher trophic levels during periods of low dietary EPA supply.

Summary: Stable isotope analysis of 1257 global lakes reveals that most lakes are dependent on precipitation and groundwater, with approximately 20% of water inflow lost through evaporation and some lakes experiencing extreme evaporative losses. This highlights the importance of systematic isotopic monitoring to detect the impacts of climate change and catchment-scale variations on lake water-balance budgets.

Summary: Stable isotopes of hydrogen, nitrogen, and carbon are used to analyze movement patterns and trophic relationships among different species. The study found that rearing environment and family-related effects can influence the isotopic composition of tissues. The isotopic composition of swallows and kestrels was affected by the rearing environment, while the isotopic composition of mallards was influenced by energy expenditure.

Summary: Nitrate stable isotopes were measured to understand nitrate contamination and microbial cycling processes. In the Fischa-Dagnitz spring and river system in Austria, nitrate concentrations showed minor annual variance, while nitrate isotopes exhibited surprising variability. The isotopic composition helped differentiate between denitrified groundwater inputs and biochemical cycling processes, despite the stable nitrate concentration.

Summary: Non-exchangeable hydrogen-isotope (62Hn) measurements are important in forensics for sample authenticity, traceability, and provenance determination. However, the measurements are often complicated due to uncontrolled exchangeable hydrogen and moisture contamination, leading to incomparability among laboratories. A revised technical solution (UniPrep2) is introduced to control hydrogen-isotope exchange and enable robust online sample drying and vapor equilibration. This solution empowers isotope analysts to conduct reproducible controlled vapor equilibrations and vacuum-oven evacuation with helium drying, providing accurate and precise 62Hn values for various organic sample types.
