In species with separate sexes, females and males often differ in their morphology,
physiology and behaviour. Such sex‐specific traits are functionally linked to variation in …

Environmental light is perceived and anticipated by organisms to synchronize their
biological cycles. Therefore, artificial light at night (ALAN) disrupts both diurnal and seasonal …

Day length in conjunction with seasonal cycles affects many aspects of animal biology. We
have studied photoperiod-dependent alterations of complex behavior in the teleost, medaka …

Species with intense male–male competition for access to females often show alternative
reproductive tactics (ARTs) where males of lower competitive ability adopt a sneaky …

Snail Bellamya purificata is not only useful for bioremediation, purifying aquaculture
environments, but it is also a commercially valuable and nutritionally rich aquatic product. To …

Sexual selection research has long focused on the evolution of female mate preferences.
Most of the models that have been developed posit that mate preferences evolve in a mating …

Biases in adult sex ratios can alter the intensity of sexual selection by enhancing competition
for mates. Under intense competition males increase their investment in behaviors to …

Woundfin Plagopterus argentissimus are a small, endangered cyprinid found solely in the
Virgin River across Utah, Arizona, and Nevada. As of now, only three facilities culture …

We review the behavioral and physiological ecology of rubyspot damselflies before, during,
and after copulation. Adult rubyspots are sexually dimorphic, with males bearing a red wing …

Male harassment toward females during the breeding season may have a negative effect on
their reproductive success by disturbing their foraging activity, thereby inducing somatic …
