Cadernos de saude publica, 2021
In January 2020, the population of Greater Metropolitan Rio de Janeiro, Brazil, suffered deterioration in the quality of the public water supply, caused by the presence of geosmin, which compromised the water treatment process at the Guandu Water Treatment Plant, the only water source in the region.

Detection of Linkage Between Solar and Lunar Cycles and Runoff of the World's Large Rivers

Earth and Space Science, Volume 6, Issue 6, Page 914-930, June 2019., 2019
Abstract It is an ongoing concern that global hydrological cycle can be likely intensified under context of climate change and anthropogenic actions. Here, our results show that the solar and lunar periodic motions (SLPMs) have substantial impact on the runoff of the world's large rivers. We estimate that SLPMs can produce a change of the world's large

Subtle variation in size and shape of the whole forewing and the red band among co‐mimics revealed by geometric morphometric analysis in Heliconius butterflies

Ecology and Evolution, Volume 8, Issue 6, Page 3280-3295, March 2018., 2018
Diagnosable and consistent wing shape differences in the postman mimetic‐ring traits were found. Sexual dimorphism in the forewing red band shape was found for H. erato, H. besckei, and H. melpomene. Concurrent natural and sexual selection might underlie wing patterns variation in Heliconius postman ring. Abstract Heliconius are unpalatable butterflies

Estimating the Potential Production of the Brown Mussel Perna perna (Linnaeus, 1758) Reared in Three Tropical Bays by Different Methods of Condition Indices

Journal of Marine Sciences, Volume 2015, Issue 1, 2015., 2015
Perna perna (Linnaeus, 1758) is the main marine bivalve mussel yielded commercially in Brazil. In spite of this, scientific data is very scarce regarding its productivity in tropical shallow waters. The Condition Index (CI) is used worldwide in mariculture to assess animal health, harvest time, and yield. In this study, the authors used CI results from

Plant growth‐ promoting bacteria inoculation and co‐inoculation effects on Palisade grass (Urochloa brizantha cv. Marandu) in ferralsol in Amazonas State, Brazil

Soil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract Deforestation is primarily driven by three main factors the conversion of the Amazon rainforest into pastureland, agriculture, and mining, as well as land invasion. These pastures are mostly degraded, and it is necessary to restore their productive capacity. Microbial inoculants can be used to increase nutrient use efficiency. The objective of
