Abstract:
... Determining the levels and spatial distribution of potentially toxic elements (PTEs) is essential in designing mitigating strategies to remediate contaminated areas. Efficient prediction of PTEs is difficult due to high spatial variability and multiple sources of contamination. The use of machine learning algorithms is an alternative for the improvement of the predictions. Objective of the study w ...

Abstract:
... Deep learning (DL) is a cutting-edge technology that enables high-throughput phenotyping in aquaculture. The routine application of DL offers new opportunities for the genetic selection of appearance traits, especially those related to body shape. The criteria currently used for the trait selection of commercial interest, such as rapid growth and weight gain, can directly influence the animal's ap ...

These volcanoes show a wide variation in morphologies despite being formed by the same migrating mantle plume under the lithosphere. In this work, the volcanic edifices associated with the Alignment 3 were examined in t ...

Abstract:
... Cephalopods have upper and lower chitinous beaks, and their shape can be used to identify species. However, the morphological attributes of beaks are commonly obtained from sources that contain little information on shape, compromising the determination of taxa. Thus, in this study, we used geometric morphometrics to analyze inter-specific differences in beak shape of six octopus species from the ...
