Summary: This study investigated the effects of tebufenpyrad on shrimp, gastropods, macrophytes, phytoplankton, bacteria, and water quality. The results showed that tebufenpyrad suppressed the population of certain species but stimulated others. It also had a negative impact on water quality indicators.

Summary: Individuals exposed to predation risk can produce offspring with altered phenotypes. Most research focuses on maternal effects or generalized parental effects, but our study examined both maternal and paternal effects and the interactions between them. We exposed snails to predator cues and created mating pairs with different parental treatments. Offspring size was affected by maternal exposure, but this effect was negated when the father was also exposed. Our findings demonstrate potential conflict between male and female parental effects and highlight the importance of studying the interactions between maternal and paternal effects.

Summary: This study demonstrates that freshwater snails, particularly Physa acuta, can serve as promising sources for isolating new antibiotic-producing actinobacterial species. A novel Streptomyces species 7NS3 isolated from these snails shows activity against Gram-positive bacteria, leading to the identification of a gene cluster potentially coding for emycin A biosynthesis through genome mining. The study highlights the potential of exploring unconventional environments like freshwater snails for discovering new bioactive metabolites.

Summary: Contamination by pharmaceutical pollutants poses a critical threat to aquatic ecosystems. A study found that long-term exposure to the antidepressant fluoxetine reduces behavioral plasticity and egg mass production in freshwater snails, highlighting the potential harmful effects on non-target organisms and population resilience.

Summary: Understanding the reproductive biology and population dynamics of threatened species is crucial for conservation efforts. Heleobia atacamensis, a freshwater snail found only in the Atacama Saltpan in Chile, was studied for its reproductive strategy, recruitment period, sex ratio, and sexual dimorphism. The research revealed that this oviparous species has direct development, recruitment occurs throughout the year, sex ratio is 1:1, and sexual dimorphism was not detected. The results provide valuable information for future conservation management plans.

Summary: The present investigation revealed that the infection of papaya leaves by PaLCuV resulted in significant changes in the anatomy, physiology, and pharmacological properties of the leaves. The infected leaves showed reduced stomatal density, photosynthesis rate, and enzymatic activity, while the size of guard cells, transpiration rate, and anthocyanin content increased. Moreover, the pharmacological potential of the infected leaves was significantly decreased.

Summary: The study found that exposure to gluconic-acid functionalized IONPs and FeCl3 resulted in various gonadal histopathological changes in snails, with GLA-IONPs inducing a more intense inflammatory response. Environmentally relevant concentration (2.5 mg L-1) of both GLA-IONPs and FeCl3 led to high gonadal histopathological indices, indicating their potential reproductive toxicity.

Summary: The glymphatic system is a waste clearance system in the brain that helps clear neurotoxic peptides like amyloid-beta. Impaired function of this system exacerbates disease pathology in neurodegenerative diseases. Our study shows an adaptation of a technique used to study the glymphatic system in pigs, bridging the gap between rodent and human studies.

Summary: The study compared the performance of local Italian tomato cultivars and commercial cultivars under drought conditions, dividing them into tolerant, susceptible, and intermediate groups. Selection of drought-tolerant cultivars could lead to more sustainable agriculture and less wasteful irrigation plans.

Summary: This study aims to determine the ecological preferences and major environmental variables associated with P. acuta abundance and distribution in Douala urban streams. The results showed that urban streams in Douala are severely impaired, especially downstream of industrial effluents. Important environmental variables include dissolved oxygen, biochemical oxygen demand, alkalinity, salinity, pH, water depth, wetted width, zinc, iron, cadmium, encumbrance rate of sediment and sediment types.

Summary: Sonneratia caseolaris is a pioneer species in mangrove that can grow in both saltwater and freshwater. The study found anatomical differences in roots, stems, and leaf blades of S. caseolaris plants growing in different conditions, with root periderm playing a crucial role in salt exclusion. Tanniferous cells were associated with salt elimination in saltwater plants.

Summary: This study aimed to investigate the remediation potential of wood-chip biochar and gallic acid on the growth of Solanum melongena under salinity and boron stress. The results showed that biochar and gallic acid treatment improved germination percentage, biomass, and stress tolerance of the plants. Additionally, they also increased chlorophyll and soluble sugar content, while decreasing malondialdehyde, hydrogen peroxide, and glycine betaine.

Summary: Sugar gliders, as small marsupials, present challenges for clinical veterinarians as they lack accessible references regarding their internal anatomy. In this study, the female genital apparatus of sugar gliders was examined, revealing the presence of duplicate reproductive organs and a unique vaginal complex. The dissected carcasses of eight mature females were used to explore the macroscopic anatomy of the female reproductive system in this species. This knowledge is essential for accurate diagnosis and treatment of pathologies in sugar gliders.
