Summary: The chemical composition of seedlings and adult plants of several Piper species show significant differences, with adult leaves accumulating various secondary metabolites while seedlings produce entirely different compounds. This variation raises questions about changes in herbivore pressure across ontogeny.

Summary: This study investigates the extent to which American manufacturers reconfigured their supply bases during President Trump's tenure in response to increasing institutional pressures and business uncertainty. The findings show that American manufacturers reduced the spatial complexity of their supply bases and concentrated their purchase spend to fewer suppliers over time. However, contrary to the aims of governmental policies, they increased their dependence on foreign suppliers and reduced their dependence on local ones.

Summary: This study presents a comprehensive histological ontogenetic analysis of the daubed shanny from the Arctic, focusing on the postlarvae transition from pelagic to benthic lifestyle. The research examined various organs and tissues, including the thyroid, heart, digestive tract, liver, gonads, blood, and lipid sac, in different developmental stages. The study found that the daubed shanny exhibits structural characteristics of marine fish in cold, high-oxygen polar waters, and suggests that the presence of a lipid sac and the absence of distinguishable red blood cells in pelagic postlarvae are unique adaptations for successful growth and development in the Arctic environment.

Summary: This study examines the effect of lighting and environmental factors on the skin color change in alligators. The results show that maintaining juvenile alligators in black enclosures led to a gradual lightening of skin color when shifted to white enclosures. Histological examination revealed differences in the pigmented layer of the skin between dark and light environments. The study also suggests that the ontogenetic loss of stripes in alligators may aid in crypsis and predation. Additionally, the darker color of larger alligators may play a role in thermoregulation, particularly for individuals living in colder climates at the northern end of their range.

Summary: The hypothalamus plays a crucial role in regulating homeostasis, biological rhythms, adaptation, and aging. This study found the presence of Lin28-immunoreactive neurons in the ventromedial nucleus of the hypothalamus and their absence in other studied nuclei. The percentage of Lin28-positive neurons increases with age, peaks at 6 months and 1 year, and then declines. These neurons also colocalize components of insulin signaling, indicating their involvement in metabolic regulation. The findings suggest that Lin28 expression in the hypothalamus changes with development and signaling components.

Summary: The study found that Nestin and Sox2 double-expressing NSCs were observed in the AC area of mice from P3 to 4M in vivo, while the number of NSCs reduced significantly with age. In vitro, the neurosphere forming capability, cell proliferation, and percentage of Nestin and Sox2 double-expressing NSCs also decreased significantly with age.

Summary: Study of the proton-rich T-z = -1 nucleus Kr-70 through inelastic scattering reveals a deviation in the electromagnetic matrix elements compared to other isotopes Br-70 and Se-70, suggesting a violation of isospin symmetry at this level not previously observed. Current nuclear structure theories are unable to quantitatively explain this anomaly, possibly indicating a shape change between Kr-70 and Se-70 contrary to model predictions.

Summary: Jumbo squid plays a crucial role in the food webs of the eastern Pacific, but its trophic ecology is complex due to its highly migratory and opportunistic predatory behavior. This study investigated the ontogenetic and spatiotemporal shifts in the feeding strategies of jumbo squid using stable isotope analysis. The results showed that both year and area significantly influenced the stable isotope values, while sex and stage had no significant effect on the values. The study also revealed that the habitat and feeding habits of jumbo squid changed with the growth of individuals and differed among different areas.

Summary: This study compared the relationship between metabolic scaling and body shape in American eels, and identified the factors influencing metabolic scaling during eel development. These findings are important for understanding the geometric theories of metabolic scaling and the growth and development of eels.

Summary: This study investigated the relationship between tooth morphology and ontogenetic niche shift in bull sharks. The results showed significant ontogenetic differences in tooth morphology at different sizes and jaw positions, but each morphological aspect retained the same tooth groupings throughout the process, which is related to tooth strength, prey handling, and heterodonty.

Summary: The study analyzed the magnitude of integration in the skull of Macaca fascicularis throughout ontogeny. Results showed that most skull modules were more tightly integrated than the skull as a whole. However, there were exceptions in certain modules, reflecting the influences of early brain growth/development and changing functional demands. The relationship between evolutionary flexibility and developmental/functional mechanisms was complex due to the skull's multifunctionality and various ossification origins.

Summary: The feeding behavior in the Danube crested newt undergoes significant changes throughout different ontogenetic stages, involving adjustments in food search, approach, and uptake mechanisms. These changes reflect an evolutionarily defined relation between locomotor and feeding systems control, with a switch from successive to integrated control during ontogeny, triggered by the formation of functional limbs in late larval development.

Summary: During the Great Resignation, more than 4.5 million people have changed jobs. Career transition-related stress ranks among the top 25 causes of stress. This stress can be alleviated through social support models, career transition planning, and personal brand strategy frameworks, facilitating continuous learning and growth.

Summary: The study found significant sexual dimorphism in cranial shape and size in brown rats, with males being larger and displaying variation around the brain-case, while females showed greater variation around the occipital bone. Additionally, there are subtle age classes during ontogeny in the skull morphology.

Summary: The zebrafish, a widely used model species, has been studied extensively in various research fields. However, little is known about its blood osmolality. In this study, we measured the blood osmolality of zebrafish at different stages of postembryonic development and found significant changes in osmolality during growth and metamorphosis.
