Resumo: As mudanças climáticas globais exercem diferentes efeitos negativos ao redor do mundo, e a seca extrema de 2019-2021 observada no Pantanal parece derivar desses efeitos. Espécies aquáticas e semiaquáticas ocorrem em abundância no Pantanal, devido à grande oferta de ambientes sazonalmente inundáveis. O jacaré-do-pantanal, Caiman yacare, que na década de 1990 apresentou população estimada em cerca de 3 milhões de indivíduos, apresenta declínio populacional devido à escassez de água nos rios, lagos e açudes restantes. A espécie responde às secas, adotando estratégias de sobrevivência como a estivação na lama e no interior da floresta. Recomendamos três medidas gerais para a conservação do Pantanal como um todo e cinco ações específicas de manejo para minimizar os efeitos da seca nas populações de jacarés no Pantanal. Abstract: Global climate change has negative effects in different ways around the world, and in the Pantanal the extreme drought of the last three years seems to be one such scenario. Many aquatic or semi-aquatic species occur in the Pantanal due to a large availability of seasonally flooding habitats. In the 1990s, the population size of the Pantanal caiman, Caiman yacare, was estimated at around 3 million individuals, but at present, it faces a decline due to the water scarcity in the remaining rivers, lakes and water holes. The species responds to the droughts adopting survival strategies such as aestivation in the mud and in the interior of the forest. We recommend three general measures for the conservation of the Pantanal ecoregion and five specific management actions to minimize the effects of drought on caiman populations for the Pantanal.

Background: Asian soybean rust (SBR) caused by Phakopsora pachyrhizi Syd. & Syd., is one of the main diseases affecting soybean and has been reported as one of the most economically important fungal pathogens worldwide. Knowledge of the genetic diversity of this fungus should be considered when developing resistance breeding strategies. We aimed to analyze the genetic diversity of P. pachyrhizi combining simple sampling with a powerful and reproducible molecular technique. Results: We employed Amplified Fragment Length Polymorphism (AFLP) technique for the amplification of P. pachyrhizi DNA extracted from naturally SBR-infected plants from 23 production fields. From a total of 1919 markers obtained, 77% were polymorphic. The high percentage of polymorphism and the Nei's genetic diversity coefficient (0.22) indicated high pathogen diversity. Analysis of molecular variance showed higher genetic variation within countries than among them. Temporal analysis showed a higher genetic variation within a year than between years. Cluster, phylogenetic and principal co-ordinate analysis showed that samples group by year of collection and then by country sampled. Conclusions: The study proposed combining a simple collection of urediniospore with a subsequent analysis by AFLP was useful to examine the molecular polymorphism of samples of P. pachyrhizi collected and might have a significant contribution to the knowledge of its genetic diversity. Also, AFLP analysis is an important and potent molecular tool for the study of genetic diversity and could be useful to carry out wider genetic diversity studies.
