Article Synopsis
- Otoliths play a crucial role in marine biology, aiding in studies related to fish metabolism, age, growth, and stock identification for sustainable management.
- The research utilizes micro-computed tomography to analyze otolith density variations but notes a lack of methodologies for comparative studies, leading to the application of the Ball Mapper technique in this analysis.
- This study emphasizes reducing computational costs through probabilistic sampling, validating sample representativeness, and uncovering significant correlations between age and network properties, showcasing the effectiveness of the Ball Mapper in processing tomographic images.
Functional morphology investigates the relationships between morphological characters and external factors, such as environmental, physical and ecological features. Here, we evaluate the functional relationships between body shape and trophic ecology of a tropical demersal marine fish community using geometric morphometrics techniques and modelling, hypothesizing that shape variables could partially explain fish trophic level. Fish were collected over the continental shelf of northeast Brazil (4-9°S).

Method: a retrospective, observational study with a sample composed of individuals registered in the kidney transplant section of the application from July of 2018 to April of 2021. Demographic data, data entry, time of use, weight, blood pressure, blood glucose, creatinine, medication schedules, appointments, and tests were the variables collected.
Mycteroperca bonaci (black grouper) is one of the most sought species of grouper along its entire distribution, being a prime target for demersal line fisheries because of its high commercial value. Nonetheless, because of population declines the species is considered near threatened according to the IUCN red list. The present study aimed to determine the population parameters of M.

Objective: To analyze the temporal trend of Food and Nutrition Surveillance System (SISVAN) coverage and nutritional status of adults undergoing follow-up in the Brazilian Primary Health Care, 2008-2019.
Methods: This was an ecological time series study using data on Brazilian macro-regions. The annual percent change in the classification of nutritional status and total coverage was estimated using the Prais-Winsten regression model.
