Summary: New data on the chemical composition of basalt glasses collected in the anomaly region of the Mid-Atlantic Ridge provide insight into the compositional variability and potential source materials. The study indicates that the glasses show a wide range of compositions and could originate from both depleted mantle and other source materials. The results suggest two alternative hypotheses, partial melting of continental crustal material and melt-rock interaction within off-axial gabbro structures, as potential mechanisms for the compositional diversity observed in the samples.

Summary: The development of zero-valent species of group 13-15 elements has been reinterpreted with the use of Lewis bases to stabilize such species. This has led to the isolation of E-n(0) derivatives with a variety of bonding and structural motifs due to the diversity of Lewis bases available. The exploration of allotrope chemistry relevant to materials science is proposed as a potential future direction for zero-valent main-group chemistry at the end of the article.

Summary: The study evaluated Tilia cordata leaves as bioindicators of heavy metal pollution and found that leaves from urban areas like Bilbao had higher heavy metal concentrations related to traffic emissions. The analysis of leaf carbon and nitrogen isotopes (delta C-13 and delta N-15) showed potential as indicators of heavy metal pollution levels and could distinguish pollution sources in different locations. Further research is needed to calibrate this monitoring tool through extensive vegetation screening.

Summary: Many important biological components contain nitrogen. However, N-15 nuclei are rarely used in NMR-based metabolite assignment due to their low abundance and the lack of comprehensive databases. In this study, a broadband N-15-edited H-1-C-13 HSQC NMR experiment was developed to identify nitrogen-containing metabolites based on their C-13, H-1, and N-15 chemical shifts.

Summary: This study is the first to provide a year-round and pluriannual description of the minimum acoustic occurrence of baleen whales in eastern Canada. It reveals that blue, fin, and humpback whales occur year-round off eastern Canada, challenging the traditional seasonal migration narrative. The Scotian Shelf region and Flemish Pass-Orphan Basin areas are particularly important for these whales and should be the focus of future research.

Summary: This study examines the summer distribution of fin and humpback whales in the Norwegian Sea from 2013 to 2018, finding a pronounced northerly shift in distribution for both species related to the availability of prey such as pelagic fish and euphausiids. The results also suggest that recent prey composition for these whales contains a large proportion of fish and that the distribution patterns are impacted by direct or indirect interspecific interactions, particularly with killer whales.

Summary: The study examines the factors contributing to the deglacial Atlantic mid-depth delta C-13 change, finding that the increased remineralization due to the weakened AMOC plays a dominant role in the decrease of delta C-13. The surface end-members should be used in diagnosing mechanisms of delta C-13 changes, as their remineralization is more critical than that along the transport pathway to the deep ocean.

Summary: Carbon isotope fingerprinting using multivariate analysis has been applied in ecological studies to measure essential amino acids. This study evaluated the consistency in isotopic fingerprints among nearshore primary producers and identified the biochemical mechanisms driving these patterns. The results showed a high consistency in isotopic fingerprints of marine algae across space and time, with kelps and rhodophytes exhibiting distinct patterns. Taxonomy and site locality were found to be important determinants of individual amino acid delta C-13 values.

Summary: Endocannabinoids 2-arachidonoyl-glycerol and N-arachidonoyl-ethanolamine are lipids that regulate various physiological processes, including inflammation, and are being studied as potential anti-inflammatory agents. Human eosinophils and neutrophils have been found to metabolize 1-linoleoyl-glycerol (1-LG) and N-linoleoyl-ethanolamine (LEA) into novel endogenous 15-lipoxygenase metabolites 13-HODE-G and 13-HODE-EA, although the biological significance of these metabolites is not yet fully understood.

Summary: Changes in habitat and foraging behavior of Pacific walruses may impact their exposure to toxic and essential trace elements. Female walruses have higher concentrations of toxic and essential elements compared to males. Pregnant and nursing females may be more vulnerable to changes in prey availability due to their narrower range of element concentrations.

Summary: The large variation in marine mammal skull and dental morphology reflects ecological specializations, while the drivers of intraspecific variation in skull shape are less understood. In this study, the authors assess intraspecific variation in grey seal skulls and find that there is a large variation within populations and slight differences between populations. This variation may be a result of balancing selection or phenotypic plasticity, leading to a generalist foraging behavior. The large overlap in skull shape between populations questions the separate subspecies status of Atlantic and Baltic Sea grey seals from a morphological perspective.

Summary: Pregnancy and lactation are energetically expensive processes for female mammals and have significant impacts on species-specific reproductive strategies. The lactation strategy of harbor seals is believed to be intermediate between sea lions and true seals. This study characterized the fatty acid composition of blubber in pregnant and lactating harbor seals and compared it to other pinnipeds. The results showed that pregnant harbor seals prioritize the storage of polyunsaturated fatty acids (PUFAs) in their blubber, while lactating harbor seals exhibit similar fatty acid profiles to other true seals.

Summary: Extant odontocetes exhibit variation in body size, brain mass, biosonar mode, feeding strategies, and diving and habitat adaptations. The skull morphology of odontocetes showed a strong phylogenetic signal, with size being more strongly associated with ecology than shape. After accounting for phylogeny, significant associations were found between skull size and various ecological factors. However, the associations between skull shape and ecological variables were not supported after phylogenetic correction, suggesting that ecomorphological feeding adaptations vary more between odontocete families and are constrained by size.

Summary: In this study, the utility of leopard seal whiskers as a biomonitoring tool for tracking contaminants and monitoring the health of Antarctic flora and fauna was examined. The analysis of leopard seal whiskers revealed variability in non-essential trace elements over time that could be partly explained by changes indict. The levels of mercury (Hg) in the whiskers were not high enough to indicate high risk of Hg toxicity, but the maximum Hg concentrations observed were higher than those measured two decades ago. The study also suggested that selenium (Se) may detoxify the Hg burden in leopard seals.

Summary: Climate change poses a threat to fisheries health, but its effects on the physiology and ecology of commercial fish populations are not well understood. In this study, growth increments of female yelloweye rockfish opercula were analyzed to reconstruct lifetime steroid hormone, stable isotope, spawning, and stress data. The results suggest that increasing sea surface temperature may negatively affect the reproductive development of juvenile and subadult females. Spawning frequency was found to be linked to changes in climate indices, indicating favorable conditions for larval survival.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.
