Summary: This study investigates the interactions between neonicotinoids and natural environmental stressors in wood frogs and highlights the importance of including behavioral assays and natural stressors in studies of amphibian ecotoxicology. The results show that imidacloprid and population density can affect the behavior and development of wood frogs, especially in the presence of predation cues.

Summary: The study suggests that munition exposure can alter tadpole skin microbiome composition and affect the transcriptional profiles in the amphibian host, potentially impacting the host's health and immune status. The findings indicate direct effects of munitions exposure on the skin microbiome, as well as possible indirect effects on microbial flora. The research highlights the importance of understanding the potential impacts of munition exposure on amphibian health and disease resistance.

Summary: Different bacterial skin microbiome compositions were found in North American wood frogs based on seasons and locations, with no significant effect of sex on microbiota diversity observed. The study indicates significant seasonal variation in wood frog skin microbiome structure, while the average diversity per frog remained consistent.

Summary: Glycoconjugates, such as glycoproteins, play important roles in mammalian cells and have a wide range of potential applications. Lignocellulosic biomass (LCB) is a promising source of carbohydrates for producing synthetic glycoconjugates. This review highlights recent advances in glycobiology, therapeutic properties, and the application of glycoconjugates, as well as the potential of LCB for glycoconjugate production.

Summary: Anuran metamorphosis is associated with changes in thyroid hormone levels and gene expression. New technology allows for measuring TH levels and gene transcription during metamorphosis. The concentration profile of T2 during metamorphosis suggests its role in anuran development.

Summary: This study developed a new method of single-cell sequencing to analyze the perturbation patterns of cell type-related gene expression in neotenic and metamorphosed axolotls. By analyzing gene expression of over 1 million single cells, the first adult axolotl cell landscape was constructed. Comparison of single-cell transcriptomes between tissues of neotenic and metamorphosed axolotls revealed the heterogeneity of non-immune parenchymal cells in different tissues and identified their regulatory network.

Summary: The interactions between bacterial lectins and carbohydrates on the host cell surface play a crucial role in bacterial adhesion and other processes. Synthetic multivalent glycoconjugates can provide insights into the nature of glycan-bacteria interactions and contribute to the design of effective bacterial inhibitors.

Summary: This study evaluates the toxicity of the widely used fungicide tebuconazole on the embryo-larval development of the South American toad Rhinella arenarum. The results show that larvae are more sensitive to tebuconazole than embryos, but toxicity increases significantly in embryos with chronic exposure. Tebuconazole causes several sublethal effects on embryo development and accelerates metamorphosis at low concentrations.

Summary: Exposure to cadmium negatively affects metamorphosis, growth, and kinetic ability of Rana zhenhaiensis, damaging the thyroid gland and impairing skeletal development, which leads to reduced survival.

Summary: This study examines the chronic effects of a complex PFAS mixture on amphibian growth and development. The findings suggest that the toxicity of PFOS and other PFAS mixtures is additive, and that PFOS is not inherently more toxic than other mixture components.

Summary: The background color has an impact on the welfare of captive brown frogs. The study found that brown frogs prefer black backgrounds, regardless of feeding and time of day. Therefore, it is recommended to use more black backgrounds for captive brown frogs to provide a suitable living environment.

Summary: The present study evaluated the impact of dietary quality on the effects of chemical stressors on premetamorphic development and metamorphosis in tadpoles. The results showed that suboptimal dietary quality negatively affected both growth and metamorphic development, and iodine supplementation only partially compensated for the effects on metamorphosis.

Summary: This study investigates the effects of organic compounds in oil sands process-affected water on wood frogs. The results show that these compounds have no significant effect on mating behavior and fertility, but they decrease offspring viability and development, which may impact the recruitment of native amphibian populations.

Summary: In this study, lectin histochemistry was used to compare the cellular localization of sugar residues in bull and donkey testes. While the basic testicular structure was similar in both species, different lectin localization patterns were observed in cellular components. Statistical analysis did not show a significant association between labeling intensity and different variables, but a stronger response was observed in donkey testes compared to bull testes.
