Summary: The circadian clock in holometabolous insects regulates the daily rhythmicity of emergence by controlling the hormone receptor-mediated actions of the molting hormone. This rhythmicity depends on the coupling between the central clock in the brain and a peripheral clock in the prothoracic gland.

Summary: Insect wings need to be flexible, light, and strong for dynamic behaviors. The study on Brood X cicadas reveals that, after eclosion, their wings unfold and expand with the help of circulating hemolymph, which is later pumped out, resulting in a strong yet lightweight wing structure.

Summary: This article reviews the current status and challenges of decapod crustacean farming from an animal welfare perspective. It proposes potential welfare indicators and critically evaluates the scientific evidence of sentience in commercially important decapods. Despite extensive research in stress physiology, immunology, and disease control, there is still limited knowledge on key parameters related to welfare dimensions. The article recommends further research to develop a comprehensive welfare assessment and species-specific welfare indicators for all farmed decapod crustaceans.

Summary: In this study, the roles of ETH, EH, and CCAP in molting regulation in crabs were investigated. The results showed that these hormones play essential and distinct roles in the molting cycle of crabs, and there is interaction among them. These findings contribute to our understanding of the different mechanisms of molting regulation in insects and crustaceans.

Summary: Decapod crustacean welfare is important in legislative and cultural/fishery contexts. However, there is no consensus on a common measure of stress for crabs, lobsters, and shrimp. This study found that L-lactate levels in the hemolymph can serve as a physiological indicator of stress in decapod crustaceans, complementing existing indicators of condition/vigour.

Summary: The study revealed that in Leptinotarsa decemlineata, the expression of eclosion hormone (EH) is regulated by 20-hydroxyecdysone (20E), and EH plays a crucial role in ecdysis and trachea clearance. The changes in EH levels can lead to abnormal phenomena in the larva-to-pupa-to-adult transition phase.

Summary: This review summarizes the current status of interspecific hybridization in crustacean species and discusses its potential for crustacean aquaculture production. Cross-breeding of shrimp and lobster species has been supported by artificial insemination technology, while crabs still rely on natural mating. Interspecies hybridization of crustacean species has also been observed in nature.

Summary: This study cloned and analyzed the expression levels of three neuropeptide genes in different developmental stages and wing types of S. furcifera. The results showed that these genes encoded peptides with different lengths and exhibited differential expression among genders and wing types. Furthermore, the relative expression levels of these genes were affected by sublethal concentrations of a pesticide.

Summary: This study investigates the functional role of ecdysis-triggering hormone in hemimetabolous insects using Rhodnius prolixus as an experimental model. The results show that ecdysis-triggering hormone plays a crucial role in regulating the ecdysis process, but has minimal effects on ovarian maturation. This study provides important insights for evolutionary entomology and pest control strategies.

Summary: The Nagoya Protocol is a legal framework for fair and equitable sharing of benefits from biological diversity, with recent proposals suggesting that digital sequence information should also be subject to benefit-sharing. Formalized benefit-sharing for biological data use can increase willingness to participate in research and data sharing, fostering collaboration and preventing exploitative practices. Three case studies demonstrate how equitable benefit-sharing agreements can build long-term collaborations for global research benefits.

Summary: Insect segmentation is a well-studied system for investigating genetic regulation of development, with modelling work suggesting that limited genetic changes can explain significant differences between insect segmentation modes. The study found that Nasonia utilizes a similar gene regulatory network to Drosophila for segmentation, implying conservation of this network for at least 300 million years.

Summary: Phenotypic plasticity, the ability of organisms to produce multiple phenotypes in response to environmental changes, is a central aspect of animal adaptability. While DNA methylation is influenced by environmental cues, the exact relationship between cytosine methylation and gene expression remains unclear. More research is needed to understand the mechanisms underlying these processes.

Summary: This study investigates the molecular function of Noggin/Noggin-like genes in the arthropod pea aphid and reveals their role in regulating both bone morphogenic protein and receptor tyrosine kinase signaling pathways. Surprisingly, the clip domain is not essential for the inhibition of bone morphogenic protein signaling. These findings suggest that ancestral noggin/noggin-like genes were multifunctional regulators of signaling in the evolution of animals.

Summary: Kakapo, a critically endangered species of parrots, experienced a devastating outbreak of aspergillosis in 2019, resulting in a significant decrease in population. Genetic analysis revealed that the outbreak was caused by a single strain of aspergillus, which was present on two islands but only caused disease on one. This study provides valuable insights into the outbreak and potential strategies for future management.

Summary: The biocontrol system in New Zealand using Microctonus hyperodae is failing despite its past success. This study used RNA-seq to analyze the venom and asexual reproduction of M. hyperodae. The expanded characterization of the venom identified candidates involved in host manipulation and stimulation of the host immune system. Investigation of asexual reproduction revealed conserved expression patterns of meiosis-specific genes, suggesting the potential for sexual reproduction. The upregulation of genes involved in endoreduplication may play a role in restoring diploidy in eggs after meiosis.

Summary: The study investigated tardigrades in three temperate glaciers of New Zealand's Southern Alps and discovered two new genera and four new species through morphological and DNA analysis. The results suggest that tardigrade speciation was triggered by glacier fragmentation during the Pleistocene, making it an important model for studying allopatric divergence in glacier meiofauna.

Summary: Eusocial insect societies are characterized by reproductive division of labour maintained by reproductive dominants or queens. Queen mandibular pheromone (QMP), produced by queen honeybees, can inhibit worker reproduction and also has effects on non-target arthropods. In Drosophila melanogaster, QMP treatment mimics the starvation response, leading to reduced reproduction and changes in ovary function. These findings suggest that QMP evolved by co-opting nutrition signalling pathways to regulate reproduction.

Summary: This study investigated the role of estrogen receptors (ERs) in vitellogenesis (Vtgs) regulation in pompano fish. The findings suggest that E2 may regulate the expression of different subtypes of vtg through ERs, displaying a compensatory expression effect on the regulation of ers and vtgs. This provides a theoretical basis for further research on reproductive endocrinology in pompano fish.

Summary: Endocrine changes during bird reproduction, particularly the relationship between prolactin and incubation behavior, were investigated. The study monitored the physiological status and incubation behavior of Silkie hens over 1-2 years. The results showed that most mature hens exhibited incubation behavior multiple times, and there was a noticeable increase in nest occupancy 7-10 days before incubation onset. Protein analysis revealed that secreted prolactin during the reproductive cycle contains various isoforms, suggesting post-translational modifications like glycosylation and phosphorylation.

Summary: The COVID-19 pandemic had a significant impact on academics, particularly on those with minoritized identities or who were early career, caregivers, or had intersecting identities. The pandemic altered the impact factors of academia, including scholarly products, and affected the way individuals could respond. It is predicted that the pandemic will have long-term impacts on the population dynamics, composition, and landscape of the academic ecosystem. The number of journal submissions decreased, especially among women authors, and the pandemic heavily impacted women authors from Asia and the Middle East.
