Summary: Exposure of Chironomus riparius larvae to endosulfan resulted in significant alterations in different metabolic pathways at the molecular level, as well as modifications in all measured enzymatic activities, despite the absence of lethality. These findings highlight the need to consider effects at the sub-organismal level in addition to traditional ecologically relevant parameters in new risk assessment strategies for toxicants in the environment.

Summary: Research on microbial communities in Fe-Mn substrates from the Rio Grande Rise revealed a typical deep-sea microbiome with no significant differences in microbial community diversity among substrates. Bacterial and archaeal groups associated with oxidation of nitrogen compounds and methane oxidation were detected in these substrates, indicating their potential ecological roles in the deep Atlantic Ocean.

Summary: This study found that ibuprofen at environmental concentrations had significant effects on the survival, transcriptional levels, and enzymatic activity of Chironomus riparius. The results confirmed alterations on the development of C. riparius and essential mechanisms involved in protection against toxicological challenges. Ibuprofen poses a potential risk to C. riparius by compromising their survival, development, and ability to respond to adverse conditions.

Summary: Enigmatic toroidal carbonate concretions were discovered at a depth of 700 m in the upper plateau of the Rio Grande Rise, with a diameter of 15 cm and a central hole of 5 cm. These structures are likely formed through sediment excavation by organisms or cementation within biofilms. Further investigation is needed to uncover the actual formation mechanisms.

Summary: In recent years, there has been growing concern about the decline in insect biodiversity, particularly among freshwater insects. To investigate the impact of climate change on freshwater insects, researchers conducted a study covering Central Europe from 1990 to 2018, analyzing shifts in insect abundance and diversity in relation to temperature and precipitation. The study found increases in both richness and abundance of freshwater insects, which were influenced by changes in summer and winter temperatures and precipitation. While this is a positive sign, the overall situation for freshwater invertebrates remains critical.

Summary: This study evaluated the upper thermal tolerance of Black River P. popeii larvae and juveniles and overlaid them with water temperature and discharge data to determine thermal exceedances. The results showed that the thermal tolerance of glochidia was frequently exceeded, while that of juveniles was not. This study demonstrates how laboratory-derived physiological thresholds can be used in conjunction with environmental data to evaluate the hydrological needs of aquatic organisms.

Summary: Research has found that geothermal systems in the transboundary Mesilla/Conejos-Medanos Basin may contribute a significant amount of dissolved solids to the shallow aquifer system annually. This salinity flux, if it reaches the Rio Grande, could account for a significant portion of the river's salinity. The study also highlights the importance of identifying brackish upflow zones and their potential impacts on international water supplies in the region.

Summary: This study identified ectoparasitic mites on triatomines collected from multiple locations in the southwestern United States. The presence of mites did not have a significant impact on the T. cruzi infection status of the triatomines. Further research is needed to understand the biological impact of triatomine mites and their potential role as a biological control tool.

Summary: This study aimed to verify the linear associations between the physical, chemical and microbiological variables of spring water. The research found strong positive correlations among certain variables, indicating that the quality of spring water is influenced by the interaction between water, soil, and compounds. It was also observed that the lack of masonry protection makes the water susceptible to animal contact.

Summary: Irrigation is crucial for crop production, but it can also spread plant pathogens that cause crop damage and yield losses. This study used the ITS2 amplicon metagenomic method to evaluate the fungal diversity and presence of plant pathogens in irrigation water. The results showed the presence of potential plant pathogens in both the water reservoir and the irrigation valve at a farm, indicating the need for measures to mitigate the risks.

Summary: The study evaluated the physical impacts of diluted bitumen and surface washing agents on freshwater aquatic invertebrates, focusing on their effects on water striders. Results showed that these compounds can cause significant immobility in surface-dwelling organisms. Comparison with historic oil spill data suggested that the reported sheen thickness values could have been reached or exceeded in the majority of past spills.

Summary: The presence of pesticides in aquatic ecosystems is a major stressor for biota. Laboratory tests using model organisms are widely used for toxicity assessment, but non-model species and those from particular ecosystems could contribute to better extrapolation of toxicity data. This study explores the ecotoxicological studies of pesticides in neotropical aquatic species, focusing on bioassays performed in Argentina over the past 20 years.

Summary: This study conducted an extensive screening of Vitis species from the southwestern United States and northern Mexico for resistance to powdery mildew, identifying new sources of resistance. It was found that Western species were more susceptible to powdery mildew compared to Midwestern and Eastern species.
