Summary: Due to the wide use of Titanium (Ti) compounds, Ti and Ti nanoparticles (nTi) are released into aquatic environments, causing varying degrees of toxicity on aquatic fauna. Green macroalgae Ulva lactuca is capable of accumulating trace elements and has been extensively studied as a universal sorbent. This study aimed to evaluate the toxicity of Ti and nTi in bivalves and the remediation properties of U. lactuca. Results showed cellular damage in bivalves exposed to Ti and nTi, and the presence of U. lactuca limited the damage, possibly due to changes in water quality induced by the algae.

Summary: As the impacts of climate change continue to increase, it is urgent to incorporate climate change into future environmental policy to avoid missed opportunities. The rise of invasive species threats, exacerbated by climate change, further highlights the need for proactive measures. Recommendations include information sharing, screening and regulation of high-risk species, and incentivizing individual actions. Considering invasive species risk in climate mitigation and adaptation policy is also crucial.

Summary: Marine classification schemes are often used in marine conservation planning, but may not accurately represent biological patterns. In this study, a community-level modeling approach was used to characterize and delineate fish and invertebrate assemblages in the Northwest Atlantic. The modeling accurately predicted assemblage distributions and identified important predictors of distribution. The study also projected future distributions under a high emissions climate scenario and highlighted the importance of combining modeling with oceanographic forecasts for improved conservation planning and management.

Summary: Ecological communities and biodiversity are influenced by both abiotic and biotic factors, including extreme environments and invasive species. The increase in hydrogen sulphide episodes due to global change can threaten many multicellular organisms, while the inhibiting effect of sulphide on cytochrome c oxidase can lead to organism death. Many species possess a sulphide-resistant alternative oxidase.

Summary: Several experimental studies have shown that phytoplankton can adapt rapidly to warmed environments. However, these studies often use different experimental techniques, limiting our ability to compare thermal adaptation across different species. In this study, simultaneous long-term warming experiments were conducted on three phylogenetically diverse species of marine phytoplankton, revealing varying levels of thermal adaptation. Synechococcus sp. displayed the greatest improvement in fitness and thermal tolerance, Ostreococcus tauri showed some improvement but to a lesser extent, and Phaeodoactylum tricornutum showed no signs of adaptation. These findings can enhance our understanding of how phytoplankton communities may change in response to warming and the potential biogeochemical implications.

Summary: This study explores how marine species respond and adapt to climate change through shifting spatial distributions, with a focus on spatial constraints in different life stages. The findings show that early life stages of species are more spatially constrained than older stages, with significant species-specific variability. This highlights the importance of extending similar analyses to other species and regions to understand the impact of climate change on species distributions.

Summary: Understanding animal responses to environmental change is crucial for management of ecological traps. The study found that red-necked grebes were more likely to switch territories to ponds with high habitat quality from the previous year, regardless of the current quality. However, due to rotation of fish stocks, many ponds experienced changes in habitat quality the following year, trapping birds who had made decisions based on past information.

Summary: There is considerable uncertainty regarding which ecosystems are most vulnerable to warming. This study found strong differentiation in heat tolerance across populations in marine and intertidal taxa, but not terrestrial or freshwater taxa. Such adaptive differentiation in the ocean suggests there may be standing genetic variation at the species level to buffer climate impacts.

Summary: The temperature and osmotic stress during embryogenesis have an influence on the phenology, photosynthesis rate, growth, and water stress tolerance of Abies nordmanniana. Higher temperature during somatic embryogenesis advances budburst, but with genotype-specific responses. Osmotic stress during embryogenesis does not affect the response to water stress. The temperature during embryogenesis does not influence the optimum temperatures for photosynthesis and maximal photosynthetic rates. The height and autumn senescence of the plants vary among genotypes, but are not affected by the temperature during embryogenesis. These findings support the role of epigenetic modification in phenology and its practical applications for coping with climate change.

Summary: The authors link the effects of pCO(2) on marine invertebrates to their localized coastal habitats. They emphasize the importance of small-scale variability and adaptation. The study found that the impact of a given pCO(2) scenario depends on the deviation from the upper pCO(2) level experienced by local populations, highlighting the need to consider local adaptation and natural variability.

Summary: Environmental DNA (eDNA) metabarcoding is transforming aquatic biomonitoring by sequencing DNA/RNA to identify entire communities within a targeted group. Most studies have focused on water eDNA and macroinvertebrate samples, but eDNA metabarcoding has also been applied to soft sediment samples, especially for microbial or meiofaunal communities. Compared to traditional methods, eDNA metabarcoding offers advantages for assessing sediment environmental quality. However, there is a need for standardization to improve robustness and comparability. This review focuses on sampling, preservation, and DNA extraction protocols for sediment eDNA metabarcoding, aiming to identify best practices and promote harmonization for future benthic monitoring.

Summary: Understanding the historical onset of cyanobacterial blooms in freshwater bodies can help identify their potential drivers. Lake sediments are valuable archives for exploring these records. In this study, we compared the results obtained from a droplet digital PCR assay and high-performance liquid chromatography to analyze cyanobacterial DNA and pigments in sediment cores. Our findings suggest that the biphasic approach of combining these two methods can provide complementary information for studying changes in the cyanobacterial community.

Summary: Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) is the current gold-standard technique for detecting and quantifying messenger RNA. Droplet digital PCR (ddPCR) allows for more sensitive and accurate measurements of targeted nucleic acids without external standards. This study compared these two PCR-based methods and concluded that ddPCR is suitable for assessing gene expression in an ecotoxicological context, while RT-qPCR is more time-efficient and cost-effective.
