However, the inundation pattern of the Pantanal has been changing. For years researchers have shown that the Pantanal is sensitive to environment transformation, where faster flow and increased sediment loading may harm the inundation of the Pantanal (^{Hamilton, 2002}; ^{Junk et al., 2012}, ²⁰¹⁴; ^{De Campos et al., 2020}). Direct activities in the catchment area of the Pantanal, as the construction of dams (^{Da Silva & Girard, 2005}; ^{Da Silva et al., 2015}), and in the Paraguay River itself, as the waterway implementation (^{Gottgens et al., 2001}) impact the Pantanal inundation patterns. Moreover, we argue that the association of the direct activities and the climate change exert a fundamental effect on the river water level and the inundation time implying in serious consequences to the flood pulse of the Pantanal.

The objective was to investigate the context, approach and research topics present in the papers that analysed trace elements in beef cattle to identify gaps and scientific perspectives for the sustainable management of trace elements in livestock. The main research groups came from the United States, Spain, Japan, Brazil, India and Slovakia, which represented 31% of the papers produced. Only 37% of studies addressed aspects that integrated animal, environmental and human health. The reviewed papers concerned 56 elements and 15 bovine tissues (Cu, Zn, Pb, liver, muscle and kidney highlighted). The main gaps were (1) lack of research in developing countries, (2) the need to understand the impact of different environmental issues and their relationship to the conditions in which animals are raised, and (3) the need to understand the role of many trace elements in animal nutrition and their relationship to environmental and human health. Finally, we highlight possible ways to expand knowledge and provide innovations for broad emerging issues, primarily through expanding collaborative research networks. In this context, we suggest the adoption of the One Health approach for planning further research on trace elements in livestock. Moreover, the One Health approach should also be considered for managers and politicians for a sustainable environmental care and food safety.
