Melatonin is a much conserved feature in vertebrates that plays a central role in the
entrainment of daily and annual physiological rhythms. Investigations aiming at …

Seasonality is an important adaptive trait in temperate fish species as it entrains or regulates
most physiological events such as reproductive cycle, growth profile, locomotor activity and …

Fish have evolved a biological clock to cope with environmental cycles, so they display
circadian rhythms in most physiological functions including stress response. Photoperiodic …

The environment which living organisms inhabit is not constant and many factors, such as
light, temperature, and food availability, display cyclic and predictable variations. To adapt to …

The distribution and intensity of artificial light at night, commonly referred to as light pollution,
is consequently rising and progressively also ecological implications come to light. Low …

The timing and success of spawning in marine fish are of fundamental importance to
population persistence and distribution and, for commercial species, sustainability. Their …

The pineal organ of all vertebrates synthesizes and secretes melatonin in a rhythmic manner
due to the circadian rhythm in the activity of arylalkylamine N-acetyltransferase (AANAT)–the …

The circadian system is responsible for the temporal organisation of physiological functions
which, in part, involves daily cycles of hormonal activity. In this review, we analyse the …

Hypoxia‐ischemia (HI) of the brain not only impairs neurodevelopment but also causes
pineal gland dysfunction, which leads to circadian rhythm disruption. However, the …

Part of the life cycle of several fish species includes important salinity changes, as is the
case for the sea bass (Dicentrarchus labrax) or the Atlantic salmon (Salmo salar). Salmo …
