“…This is due to diverse environmental conditions and the high complexity of the habitats, presenting a mosaic of different phytophysiognomies. A study conducted by Maciel et al (2021) emphasizes the vulnerability of these regions, highlighting the urgent need for a substantial expansion of conservation areas.…”

One of the primary challenges in biodiversity conservation is the limited knowledge of the taxonomy and geographical distribution of species, particularly in megadiverse regions such as the Amazon In this context, the present study aimed to mitigate the Linnean and Wallacean shortfalls within the Family Leptophlebiidae (Ephemeroptera: Insecta) in the Brazilian Amazon, identify priority areas for conducting faunal inventories and enhance taxonomic knowledge of this group. Utilizing both primary Leptophlebiidae data collected in the state of Pará, and secondary data compiled from the literature on species occurring in the Amazon, we employed Species Distribution Modelling to identify areas with higher potential species richness and priority areas for faunal inventories in the Brazilian Amazon of the family. For the primary data, 2,120 specimens were identified, representing 16 genera and 28 species. Among the 28 species analysed, 7 constitute new records for the state of Pará. Additionally, two new genera, five new species and six morphospecies were identified, significantly expanding the taxonomic landscape of the family in the state. Maps depicting potential species richness and priority areas for faunal inventories in the Brazilian Amazon generated from the Modelling indicated that the states of Pará and the western region of Maranhão exhibit high potential species richness, with overlapping areas identified as priorities for Leptophlebiidae faunal inventories. In this context, this study represents a substantial advancement in the taxonomic knowledge of Leptophlebiidae in the state of Pará and the Amazon, underscoring the urgency of research and biodiversity conservation efforts for the group in the region. Furthermore, the identification of new taxa emphasizes the need for ongoing collaborative efforts to mitigate Linnean and Wallacean shortfalls.

“…In Brazil, most of the soybean are produced in the Cerrado region. A large body of scientific literature suggests that climate change already affects rainfall patterns in the Cerrado and that this weather change impacts soybean production [5][6][7][8]. Despite Brazil's increasing supply, there is still a question of whether Brazil will be able to meet China's future demand for soybean under climate change.…”

In the recent past, China has expanded its grain production to achieve high food security and increased its partial dependence on imported agricultural commodities, of which soybean supply is highly import-dependent. This study systematically reviews the past trends in China’s soybean demand, Brazil’s soybean production and export, factors contributing to the soybean trade between China and Brazil, and future uncertainty in China’s demand and Brazil’s supply under climate change. We find that recently China imported ~64% of soybean from Brazil, while ~73% of Brazil’s soybean exports were destined for China, making them key stakeholders in their international soybean trade. China’s accession to the World Trade Organization, China–Brazil trade cooperation, and diversion from trade with the USA have played a pivotal role in China’s increasing soybean imports from Brazil. China’s soybean import has brought increasing virtual land to China (from 3.57 million hectares (Mha) in 2005 to 19.63 mha in 2020). This growing virtual land import could be one of the reasons behind Brazil’s soybean harvested area, which increased from 22.95 Mha in 2005 to 37.19 Mha in 2020. In the future, climate change impacts on soybean production in Brazil can seriously affect China’s soybean imports from Brazil and its domestic food security. We analyze these effects using a climate-crop–economic modeling approach, where yield changes from the crop model are incorporated into the economic model as lower land productivity. Our results show that Brazil’s future soybean production and gross exports can drop up to 13.1% and 15.2% under the highest emissions scenario (RCP8.5). Consequently, China would face a decrease in its soybean imports from Brazil (−9.94 Mt). Due to these import reductions, China’s domestic soybean supply will be reduced (−9.94 Mt). There would also be some reduction in China’s meat supply and a drop in China’s consumer welfare. Our results can contribute to devising policies to ensure China’s food security and promote global sustainable development goals.
