The Agonistic and Reproductive Behaviors of the Gulf Killifish, Fundulus grandis and Their Physiological Components.
… for agonistic and reproductive behaviors, diel rhythms of behavior, endogenous hormone levels (testosterone for males; estrogens for females), and male coloration frequencies.In male-male pairs, dominance was quickly established and was not reversed. The dominant male often used homosexual …

ECOLOGICAL AND PHYSIOLOGICAL MECHANISMS OF BIOLOGICAL RHYTHMS IN A POLAR-BREEDING SEABIRD
Biological rhythms provide a mechanism for scheduling activity in predictably cyclic environments. During summer above the polar circle, the primary timing cue, the geophysical light-dark cycle, is highly attenuated or absent, yet some animals will exhibit diel rhythms of behavior and physiology …

Effects of size, age and photoperiod on hypoosmoregulation in brook trout, Salvelinus fontinalis
… Size, age, growth rate, photoperiod, and diel rhythms were examined for possible influences on plasma osmolarity, [Na+], [Cl-], [K+], [Mg2+], thyroxine concentration, hematocrit, and gill Na+,K+-ATPase activity of brook trout in freshwater. Significant diel cycles were found in plasma …

Biological rhythms in Aedes aegypti mosquitoes
… our results show that Ae. aegypti behavioral rhythms mediated by rhythmic gene expression are plastic and susceptible to external host cues and host blood digestion. This work can be leveraged for future studies investigating mosquito host-seeking and blood digestion to identify novel targets …

Sociality in African mole-rats : exploring how rainfall affects dispersal and genetic exchange in the Natal mole-rat (Cryptomys hottentotus natalensis)
… subterranean mammals suggest that they exhibit diel rhythms despite the lack of visual cues in their underground burrows, but it is unknown how ambient temperature, photoperiod, or individual characteristics affects their activity. I used RFID technology to monitor daily activity patterns of …
