Summary: Developmental biology has contributed greatly to evolutionary biology through the discovery of shared genes between vertebrates and fruit flies, indicating the evolution of animals from an ancestral embryonic patterning genetic tool-kit. The establishment of a morphogen gradient and the suggestion of a complex life cycle in the last common ancestor of bilateral animals are important findings in this field. The use of conserved developmental patterning systems likely placed evolutionary constraints on animal forms.

Summary: Maintaining the correct temporal order of cellular events is crucial for animal development. In this study, researchers used time-lapse microscopy to examine the timing of gene expression, cell divisions, and cuticle shedding in individual Caenorhabditis elegans larvae. They found that there was variability in timing between individuals, but this variability followed temporal scaling. Changes in temperature, diet, or genotype also influenced timing, but still adhered to temporal scaling. However, shifting conditions during development disrupted temporal scaling and changed event order in a condition-specific manner.

Summary: The study reveals the important role of serotonin in E. multilocularis development and proliferation, with evidence that serotonin is crucial for parasite integrity and survival. Serotonin also stimulates parasite metacestode development and proliferation, potentially contributing to parasite formation and growth in the liver.

Summary: By studying the model organism Lottia peitaihoensis, we have revealed important aspects of trochophore body patterning, including organizer signaling, molecular and cellular processes connecting the various developmental functions of the organizer, the specification and behaviors of the endomesoderm and ectomesoderm, and the characteristic dorsoventral decoupling of Hox expression. These findings enrich the knowledge of trochophore body patterning and have important implications regarding the evolution of spiralians as well as bilateral body plans.

Summary: Mass-rearing of mosquitoes in laboratories for population control relies on container size, which has significant effects on the mosquito's life history and productivity. Increasing container size intensifies the effects of larval density and diet on immature development time. Productivity is also impacted by container size, with larger containers having significantly lower productivity in high-density rearing conditions. Larvae tend to aggregate at the outer edges of containers, even at the cost of extreme local densities.

Summary: A novel microfluidic imaging method has been introduced to allow parallel live-imaging across multiple larval stages of Caenorhabditis elegans while maintaining worm orientation and identity. The method ensures stable worm orientation and viability, showcasing capabilities such as observing hypodermal seam and P-cell divisions, as well as the entire process of vulval development, and demonstrating feasibility of on-chip RNAi.

Summary: Many animal species undergo indirect development, producing larvae that later metamorphose into adults. Larvae have diverse morphologies and ecological niches, making them central to hypotheses about animal evolution. This review focuses on Spiralia, a clade of bilaterally symmetrical animals with a wide range of larval forms. The study examines the morphological features of spiralian larvae and discusses the potential of molecular and developmental evidence combined with modern techniques to shed light on the evolution of larvae and life cycles.

Summary: This study investigated the characteristics of haemocytes formed and released by the haematopoietic organs of Manduca sexta using specific markers and identification methods. It was found that there may be a gradual differentiation of haemocytes within the organs, and the existence of prohaemocytes in both the circulation and the haematopoietic organs, with different characteristics depending on their origin. The ablation of the haematopoietic organs reduced the number of plasmatocytes and prohaemocytes, indicating a true larval haematopoietic function.

Summary: This study aimed to investigate the effect of Debaryomyces hansenii yeast on the growth, development, and skeletal deformities of longfin yellowtail larvae. The results showed that larvae fed with D. hansenii yeast had higher survival and growth rates, increased bone mineralization, reduced skeletal deformities, enhanced intestinal function and digestive enzyme activity.

Summary: Bacteroidetes bacteria found in sponges play important roles in enhancing sponge larval settlement. The bacteria utilize strategies such as forming biofilms, secreting molecules, and producing extracellular vesicles to significantly improve settlement rates. This enrichment of Bacteroidetes bacteria in sponges establishes a basis for reciprocal adaptive co-evolution between the microbial community and animals.

Summary: This study tested the effects of different cyanobacterial strains on zebrafish larvae and analyzed their metabolomic profiles. The results showed that some strains caused morphological abnormalities, while others did not. Metabolomics also revealed the diverse compounds produced by cyanobacteria. The effects of cyanobacterial metabolites on living organisms and their associated risks are still poorly understood.

Summary: The Kuril Basin and the Kuril-Kamchatka Trench are interconnected deep-sea ecosystems with distinct characteristics of low oxygen concentration and high hydrostatic pressure. The study found that the Kuril Basin has a high abundance of nematodes and macrofauna, with a dominance of small-sized species tolerant to low oxygen levels. In contrast, the Kuril-Kamchatka Trench has a more diverse and abundant macrofauna, with a decrease in diversity and increase in abundance with depth. The high primary production of surface waters supports the diverse and abundant deep-sea bottom fauna in these areas, with a significant contribution of chemosynthetic organic carbon.
