The present study aimed to adapt a rapid river assessment protocols (RAP) to be used by elementary school children. The study was conducted in Ipameri, GO and the RAP was GUIMARÃES, A.; RODRIGUES, A.

The aim of the present study is to assess the use of rapid assessment protocols (RAPs) of rivers as environmental education (EE) instruments in elementary schools. Therefore, EE activities were proposed to students from a Brazilian public elementary school. The activities included ranged from environmental-monitoring workshops to RAPs adapted to the level of schooling of the students. The students completed questionnaires before and after the activities in order to check their degree of knowledge prior to the activities and to assess the information acquired after participation in the activities. The results established that the RAP provided and/or helped to instill social values, knowledge, skills, actions, and competences linked to the environmental conservation of local rivers. The study therefore proves that the use of the RAP would be a valuable addition to EE projects and programs in elementary schools.
The multiple uses of aquatic ecosystems by humankind and the continuous interference of their activities have contributed to the emergence of potentially toxic cyanobacteria blooms. Here, we firstly created a database of occurrences of cyanobacteria blooms in Brazil through a systematic review of the scientific literature available in online platforms (e.g. Web of Science, Capes Thesis Catalogue). Secondly, we carried out ecological niche models with occurrence data obtained from these studies to predict climatically suitable areas for blooms. We select 21 bioclimatic variables input environmental data. We used five modeling methods for the current climate scenario: (1) Maxent; (2) Support Vector Machines; (3) Random Forest; (4) Maximum Likelihood e (5) Gaussian. We found that the number of publications about bloom events was higher in 2009 with a decline in the years 2012, 2013 and 2017. Furthermore, the years with the higher records of blooms in freshwater environments were 2005, 2011 e 2014. These events occurring mainly in public supply reservoirs and are mostly of the genera Microcystis Lemmermann, 1907, Dolichospermum (Ralfs ex Bornet & Flahault) P.Wacklin, L.Hoffmann & J.Komárek, 2009 and Raphidiopsis F.E.Fritsch & F.Rich, 1929. Modeling the potential distribution of blooms, we found sampling gaps that should be targeting for future researches, especially in the Amazon biome. Overall, the models did not predict highly suitable areas in the /north of Brazil, while other regions were relatively well distributed with a higher number of occurrence records in the Southeast region.
The exploitation and degradation of natural environments exert intense pressure on important ecosystems worldwide. Thus, it is necessary developing or adapting assessment methods to monitor environmental changes and to generate results to be applied to environmental management programs. The Brazilian Veredas (phytophysiognomies typical to the Cerrado biome) are threatened by several human activities; thus, the aim of the present study is to adapt a rapid assessment protocol (RAP) to be applied to Veredas springs, by using the upper course of the Vai-e-Vem stream watershed (Ipameri County, Goiás State, Brazil). Therefore, several springs in the study site were visited and 11 of them were considered Veredas springs. After the RAP was adapted, the instrument was validated and used to environmentally assess the springs in order to demonstrate its applicability. The present study has provided an instrument of option to monitor Veredas springs.
We performed a scientometry to validate trends in the scientific production on phytotelmata and the importance of these microenvironments in the maintenance of biodiversity. We searched for articles in the Web of Science and looked at publications from 1987 to 2016. We collected years of publication, surveyed organisms, countries where the surveys took place, plants that accumulate phytotelmata, scientific journals that publish more about the topic and their respective IFs (Impact Factor) and the keywords of each article. We built a heatmap using the most frequent keywords in the studies, to investigate the topics studied over the years. We have found 293 publications, increasing over the years. Insects, anurans and crustaceans were the most studied organisms. The most studied plant families were Bromeliaceae, Poaceae and Apiaceae. The published studies analized were carried out mainly in Brazil, Argentina and Peru. The most published journals on the subject are: Zootaxa, Hydrobiologia, Biotropica and Journal of Natural History. Some main global concerns such as climate change, habitat fragmentation has gained the attention of the phytotelmata studies in the recent years. The results contribute to the knowledge about phytotelmata accumulated biodiversity and research trends.
