The water quality index (WQI) is an important tool for water resource management and planning. However, it has major disadvantages: the generation of chemical waste, is costly, and time-consuming. In order to overcome these drawbacks, we propose to simplify this index determination by replacing traditional analytical methods with ultraviolet-visibl...

There is currently no objective, real-time and non-invasive method for evaluating the quality of mammalian embryos. In this study, we processed images of in vitro produced bovine blastocysts to obtain a deeper comprehension of the embryonic morphological aspects that are related to the standard evaluation of blastocysts. Information was extracted f...

Morphological analysis is the standard method of assessing embryo quality; however, its inherent subjectivity tends to generate discrepancies among evaluators. Using genetic algorithms and artificial neural networks (ANNs), we developed a new method for embryo analysis that is more robust and reliable than standard methods. Bovine blastocysts produ...

Despite several observational studies have produced important contributions to knowledge of stream macroalgal ecology, gaps still remain about the relationship of the environment and ecological distribution patterns of these organisms. As an alternative to improve the understanding of the ecology of these algae, experimental investigations began to be conducted in Brazil. Exactly in experimental ecology of tropical stream macroalgae that this research intends to make its main contributions. In this context, two experimental studies are being proposed in order to assess (1) the influences of substrate complexity, hydraulic conditions and physical disturbances and (2) the effects of anthropogenic substances on the establishment and development of stream macroalgae. In the first study, experiments have been conducted in order to simulate the occurrence of physical disturbances on artificial substrates with five different levels of structural complexity and specific hydraulic conditions. The effects of these variables will be assessed considering as response variables richness (number of species) and abundance (percent cover and chlorophyll a content) of macroalgae. In the second study, laboratorial experiments have been conducted aiming evaluate the effects of different concentrations of glyphosate herbicides on photosynthetic responses of macroalgal species. Photosynthetic responses are assessed by two techniques: (i) chlorophyll fluorescence and (ii) dissolved oxygen evolution.
