In this study, we found moderate to strong repeatabilities in behavioural variables measuring the personality traits: activity, aggressiveness and exploration. Similarly, the probability of acting as a leader during tandem running in an emigration event was moderately (R = 0.469) repeatable.

Abstract The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and

Eye Darkening Under Dehydration Stress in the Neotropical Frog Boana punctata (Schneider, 1799). [PDF]
Dehydration induces a strong and partially reversible increase in iris pigmentation in the Neotropical frog Boana punctata. The tight relationship between iris darkening and hydration state identifies ocular pigmentation as a simple, non‐invasive physiological biomarker with broad potential for assessing hydric stress in amphibian populations ...

Abstract Anaesthetic management plays a crucial role in maintaining the welfare and physiological stability of fish during routine aquaculture and research procedures. The essential oil of Rosmarinus officinalis (ROEO) has emerged as a promising natural anaesthetic; however, its cardiophysiological effects in Amazonian species remain underexplored ...
