Seasonal changes are more robust and dynamic at higher latitudes than at lower latitudes,
and animals sense seasonal changes in the environment and alter their physiology and …

To cope with seasonal environmental changes, organisms have evolved approximately 1-y
endogenous circannual clocks. These circannual clocks regulate various physiological …

Teleosts display the highest level of brain plasticity of all vertebrates. Yet we still know little
about how seasonality affects fish behaviour and the underlying cognitive mechanisms …

Medaka Oryzias latipes has several geographically and genetically distinct populations. We
examined temperature acclimation response in various medaka cell lines derived from …

Oryzias latipes that were ready for rapid gonadal growth in spring were maintained for 4-8
wk at 16° C and 14-h light daily (14L), 14° and 14L, 14° and 12L, 14° and 10L, 12° and 14L …

The population of Japanese medaka Oryzias latipes has decreased in size because of
recent changes in the aquatic environment, and medaka are now recognized as an …

In ectotherms, age, and length at maturity typically decrease with an increase in
temperature; however, it is unclear whether this occurs in the absence of accelerated …

Many researchers found that there is a close connection between biological rhythm and
metabolism in mammals and humans. But, it is uncertain whether there is a central and …

In seasonally breeding fish species, altered fecundity, fertility, and spawning interval are
associated with changes in environmental cues such as temperature and photoperiod. To …

The eyestalks of crustaceans play an essential role in controlling a variety of physiological
functions by converting light into hormonal signals. To obtain a more complete description of …
