“…of metals such as iron and aluminum -Al (AMARAL, 2022) or even microbiological, such as Escherichia coli ( SANHUDO et al, 2021) In international studies, aquatic vertebrates such as fish are being used as bioindicators of water quality from the pressures exerted by heavy metals such as iron (Fe) on these populations (LI et al, 2019;MAHAMOOD et al, 2021). In the national territory, as well as in the Brazilian Amazon and Pará, research on the association between water quality and bioindicators is already occurring (BERSCH, 2020;GOMES, 2021) and directed to this metal because there is a presence of pathogenic microorganism's absorbers of it, which also contributes to the loss of water quality (ROMERO, 2020;STORTO, 2021).…”

Water quality, currently determined through laboratory analysis, can also be determined by the presence or absence of bioindicators sensitive to climate change, and these relationships can be the subject of studies in Environmental Education. The objective of this integrative analysis was to identify the existing gaps in physical-chemical and microbiological analyses, the use of biomonitors, the insertion of climate change and the role of Environmental Education as a fundamental complement to these analyses in the Pará Amazon, especially in the municipality of Paragominas. The secondary data were obtained from academic literatures published between 1997 and 2022, the year in which the National Water Resources Policy turns 25 years old. The data obtained and analyzed indicated that the research on water quality in the Pará Amazon, uses physical-chemical parameters, and compares the laboratory data obtained with the values established in Resolution No. 357/2005. The use of these parameters associated with aquatic bioindicators in Paragominas already presents data directed, with greater frequency, to the Uraim River, igarapé 54 and seven, which leaves a gap as to the Paragominas/Prainha River, which is a receptor of urban effluents and a tributary of the right bank of the Uraim; there are other gaps such as: scarcity of research regarding water quality and climate change are scarce; Environmental Education, although the municipality already has a plan for this, is still only applied in formal education spaces in lower and upper elementary school, but is not applied to users of water resources, which leaves them at the margins of this process. Therefore, these gaps become difficulties in the correct and active application of the NWRP.

“…Insufficient access to some metals (e.g. Fe, Mn) sensitizes both coral and symbiont responses to heat stress (Shick et al ., 2011; Biscéré et al ., 2018 a ; Reich et al ., 2020 b ; Romero et al ., 2022). However, the tipping points at which insufficient nutrient access exacerbates sensitivity to heat stress are correlated with inter‐ and intraspecific variation in metal requirements (Ezzat et al ., 2016; Reich et al ., 2020 b ).…”

“…While environmental impacts on total metal concentrations are our primary focus, we also discuss how these impacts also alter metal speciation dynamics (i.e. supplies of soluble versus insoluble metals; Hoffmann et al ., 2012) with cascading effects on the physiological capacities and functional ecology of the coral holobiont (Romero et al ., 2022).…”

“…Specifically, Fe solubility declines following seawater temperature increases (Liu & Millero, 2002). Chronic and short‐term warming may lead to decreased metal bioavailability in reef environments and represent a previously unrecognized trigger of bleaching outbreaks (Reich et al ., 2020 b ; Romero et al ., 2022). While seasonal seawater temperature fluctuations may play a role in metal bioavailability, other factors (e.g.…”

“…This is exemplified by iron (Fe) enrichment in tropical waters, which can increase primary productivity by 1–2 orders of magnitude (Martin et al ., 1994), stimulate community‐level phase shifts from coral‐dominated to fleshy algae‐dominated reefs (Kelly et al ., 2012), and facilitate marine invasions (Work, Aeby & Maragos, 2008). At the organismal level, seemingly small changes in environmental metal concentrations and stoichiometry (the mole ratio of elements) can have acute effects on physiology (Rodriguez et al ., 2016), cell replication rates (Brand, Sunda & Guillard, 1983), and ability to withstand abiotic stressors (Andrew, Morell & Strzepek, 2019; Reich et al ., 2020 b ; Romero et al ., 2022). For these reasons, trace metal research has been a focal point of polar oceanographic research during the past three decades, although less so in other marine ecosystems (Breitbarth et al ., 2010).…”

The trace metal economy of the coral holobiont: supplies, demands and exchanges

et al. 2022

View full text Add to dashboard Cite

The juxtaposition of highly productive coral reef ecosystems in oligotrophic waters has spurred substantial interest and progress in our understanding of macronutrient uptake, exchange, and recycling among coral holobiont partners (host coral, dinoflagellate endosymbiont, endolithic algae, fungi, viruses, bacterial communities). By contrast, the contribution of trace metals to the physiological performance of the coral holobiont and, in turn, the functional ecology of reef‐building corals remains unclear. The coral holobiont's trace metal economy is a network of supply, demand, and exchanges upheld by cross‐kingdom symbiotic partnerships. Each partner has unique trace metal requirements that are central to their biochemical functions and the metabolic stability of the holobiont. Organismal homeostasis and the exchanges among partners determine the ability of the coral holobiont to adjust to fluctuating trace metal supplies in heterogeneous reef environments. This review details the requirements for trace metals in core biological processes and describes how metal exchanges among holobiont partners are key to sustaining complex nutritional symbioses in oligotrophic environments. Specifically, we discuss how trace metals contribute to partner compatibility, ability to cope with stress, and thereby to organismal fitness and distribution. Beyond holobiont trace metal cycling, we outline how the dynamic nature of the availability of environmental trace metal supplies can be influenced by a variability of abiotic factors (e.g. temperature, light, pH, etc.). Climate change will have profound consequences on the availability of trace metals and further intensify the myriad stressors that influence coral survival. Lastly, we suggest future research directions necessary for understanding the impacts of trace metals on the coral holobiont symbioses spanning subcellular to organismal levels, which will inform nutrient cycling in coral ecosystems more broadly. Collectively, this cross‐scale elucidation of the role of trace metals for the coral holobiont will allow us to improve forecasts of future coral reef function.
