The number of published studies using geometric morphometrics (GM) for analysing
biological shape has increased steadily since the beginning of the 1990s, covering multiple …

Abstract The Atlantic spadefish, Chaetodipterus faber, is an economically important species
along the Southwest Atlantic Ocean, especially in the southeastern-south Brazil. Despite …

Fish diversity and ecology in the ocean's mesopelagic zone are understudied compared to
other marine regions despite growing interest in harvesting these potential resources …

The sagitta otoliths of teleostean fishes are usually used in diverse studies. Their shapes are
species-specific, and the qualitative description of their morphological features seems to be …

Life history theory predicts that organisms optimize their life-history traits according to
evolutionary context and environmental constraints. Sympatric estuarine-dependent fish are …

This study aimed to verify variations in the form of the sagitta otolith of Menticirrhus
americanus as to their ontogeny, sex and stage of such structure. Ontogenetically were …

Fish otolith shapes record ecological information of fish and are an important tool in
taxonomic, phylogenetic, and dietary studies. Shape and ontogenetic variations in the …

European perch undergoes several ontogenetic dietary shifts during its lifetime. The present
study focused on the variability in otolith shape caused by ontogenetic dietary changes in …

Sound detection in fishes relies on the inner ear and peripheral structures, such as
calcareous otoliths, which play a crucial role in perceiving movement, orientation, and …

El sentido de elaborar este libro surgió de la necesidad de brindarles a los alumnos
universitarios de grado y posgrado, interesados en la aplicación de los otolitos en las …
