Coda vocalizations recorded in breeding areas are almost entirely produced by mature female sperm whales (Physeter macrocephalus) [PDF]

open access: yes, 2008
We investigated the use and function of coda communication by sperm whales (Physeter macrocephalus L., 1758 (=Physeter Catodon L., 1758)) Codas are stereotyped patterns of clicks often made by sperm whales in social contexts. We used the pulsed structure

Visualization of poikilocytosis as an emerging erythrocytic biomarker for fish health assessment

open access: yesAnimal Research and One Health, Volume 2, Issue 2, Page 136-157, May 2024.
Poikilocytosis in fish encompasses various morphological changes in erythrocytes, including acanthocytes, echinocytes, spherocytes, dacrocytes, degmacytes, and more. This phenomenon results from both living and nonliving factors, such as pathological influences, environmental stress, anthropogenic impacts, and hereditary factors.

Characterization of α-actin isoforms in white and red skeletal muscle types of Leporinus macrocephalus (Characiformes, Anostomidae) [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2015
RESUMO Dois genes de α-actina do peixe Leporinus macrocephalus, referindo-se aos tecidos musculares branco e vermelho, foram isolados. Isoformas de actinas, que principalmente diferiram por uma substituição Ser/Ala155, podem ter uma significância funcional relacionada à interação entre actina e ATP.

Cannabinoid system of dorsomedial telencephalon modulates behavioral responses to noxious stimulation in the fish Leporinus macrocephalus

open access: yesPhysiology & Behavior, 2017
Fish dorsomedial telencephalon has been considered a pallial region homologous to mammals amygdala, being considered a possible substrate for nociception modulation in this animal group. The present study aimed to evaluate the participation of the cannabinoid system of Dm telencephalon on nociception modulation in the fish Leporinus macrocephalus.
