“…Similar correlations have been identified in freshwater [ 116 ], estuarine [Burford et al unpublished data] and coastal crustaceans [ 63 ]. Our results are also consistent with past work which suggested Fe-oxyhydroxides may be the main forms for REY uptake in amphipods [ 113 ]. However, while prawn Al, Fe and REY values had similar distribution patterns, Fe prawn patterns did not correspond with mud and Fe distribution in Moreton Bay sediment, suggesting that REY, Fe, and Al integration is more complex than simple association with muddy sediments and Fe-hydroxides.…”

“…This variation could be passed on to contiguous estuaries and reflected in local benthic species. However, research also indicates that animal REY uptake is nonlinear and can be affected by local conditions, such as changes in pH or alkalinity [ 110 , 113 ]. Therefore, prawn REY values are not necessarily an accurate representation of abiotic REY distribution.…”

A benthic bioindicator reveals distinct land and ocean–Based influences in an urbanized coastal embayment

Biogeochemical maps of coastal regions can be used to identify important influences and inputs that define nearshore environments and biota. Biogeochemical tracers can also track animal movement and their diet, monitor human coastal development, and evaluate the condition of habitats and species. However, the beneficial applications of spatial biogeochemical analysis are hindered by a limited understanding of how tracer distribution is affected by different land and ocean–based influences. To help address these knowledge gaps, we determined the spatial trends of three stable isotopes (δ13C-carbon, δ15N-nitrogen, δ34S-sulfur) and 13 major and trace elements in an urbanized coastal embayment (Moreton Bay, Australia), as incorporated into the muscle tissue of a marine consumer, the eastern king prawn Melicertus plebejus. Results were used to identify unique biochemical regions within the bay and to discuss how spatial patterns in tracers could be used to indicate the relative importance of catchment, urban and offshore drivers in coastal bays. Discriminant analysis identified seven biogeochemical regions that were likely distinguished by variation in catchment, urban, and offshore input, and habitat type. δ13C and δ15N patterns suggested nearshore areas could be distinguished by increased sediment resuspension and higher wastewater inputs from catchments. High inshore lead (Pb) and copper (Cu) concentrations were likely the result of urban input. Arsenic (As) and cadmium (Cd) increased further from shore. This trend implied oceanic influences were a significant control over As and Cd bioavailability. Cobalt (Co) and rare earths were also used to differentiate some nearshore areas, but incongruent distribution patterns in Co suggested it may be less reliable. Overall, results indicated that δ15N, δ13C, Cd, Cu, Pb and rare earth elements were the most reliable tracers to differentiate nearshore and offshore environments, and catchment–based effects. We encourage future studies to consider using a similar multivariate approach in coastal spatial analysis, and to include unrelated tracers that reflect distinct coastal influences.

“…They all belong to a larger PQQ-dependent alcohol dehydrogenase family, and MxaF comprises only one branch of them. Since lanthanides are not rare in the environment ( 17 – 19 ), methylotrophy in the presence of lanthanides might be closer to their natural lifestyle than that under lanthanide-free laboratory conditions.…”

Lanthanides have been considered unimportant for biological processes. In methylotrophic bacteria, however, a methanol dehydrogenase (MDH) encoded by xoxF was recently found to be lanthanide dependent, while the classic-type mxaFI is calcium dependent. XoxF-type MDHs are more widespread in diverse bacterial genera, suggesting their importance for methylotrophy. Methylobacterium species, representative methylotrophic and predominating alphaproteobacteria in the phyllosphere, contain both types and regulate their expression depending on the availability of lanthanides. RNA-seq analysis showed that the regulation takes place not only for MDH genes but also the subsequent formaldehyde oxidation pathways and respiratory chain, which might be due to the direct oxidation of methanol to formate by XoxF. In addition, a considerable number of genes of unknown function, including AT-rich genes, were found to be upregulated in the presence of lanthanides. This study provides first insights into the specific reaction of methylotrophic bacteria to the presence of lanthanides, emphasizing the biological relevance of this trace metal.

This paper reviews the scientific knowledge on the use of a lanthanum modified bentonite (LMB) to 25 manage eutrophication in surface water. The LMB has been applied in around 200 environments 26 worldwide and it has undergone extensive testing at laboratory, mesocosm, and whole lake scales. 27The available data underline a high efficiency for phosphorus binding. This efficiency can be 28 limited by the presence of humic substances and competing oxyanions. Lanthanum concentrations 29 detected during a LMB application are generally below acute toxicological threshold of different 30 organisms, except in low alkalinity waters. To date there are no indications for long-term negative 31 effects on LMB treated ecosystems, but issues related to La accumulation, increase of suspended 32 solids and drastic resources depletion still need to be explored, in particular for sediment dwelling 33 organisms. Application of LMB in saline waters need a careful risk evaluation due to potential 34 lanthanum release. 35 36
