Effect of light on the circadian activity rhythm of the slow loris, Nycticebus coucang
<p>In this study, the locomotor activity of a nocturnal prosimian, the slow loris (<em>Nycticebus coucang</em>), was monitored under an experimentally varied light regime. During the process of reversing their day-night cycle, activity was monitored for a light-dark cycle roughly correlating to the …

A method of detecting reaction to environmental influence by recording circadian activity, using the flagfish Jordanella floridae
… recording behavioral patterns within the diurnal activity. An apparatus measuring the activity of Jordanella floridae, Goode and Bean, using a photoelectric sensor system is described. Individual sensors monitored specific areas of the test aquarium that had special significance to the fish in the …

Estradiol exerts activational and organizational control over the expression of daily and circadian activity rhythms in mice
Robust sex differences in daily and circadian activity rhythms, as well as the manifestation of circadian disruption-associated pathologies, have been reported in numerous species, including humans and laboratory models. These differences are mediated, at least in part, by sexually dichotomous …

Markers of Circadian Disruption and Reproductive Risk Factors for Breast Cancer
Background: Circadian disruption is hypothesized to impact reproductive signaling, which in turn has long been linked to breast cancer. The melatonin hypothesis holds that increased exposure to artificial light at night and resulting inhibition of nocturnal melatonin may account for recent …

Chronobiological plasticity in Honeybee and its association with differences in the organization of the molecular pathway between central and peripheral clocks: the brain and flight muscle tissues.
Circadian rhythms govern the behavior, physiology, and metabolism of living organisms, enabling them to anticipate changes of environmental conditions. Within Insects, in honey bee s colonies an ontogeny in circadian rhythms of behavior was suggested to be related to an age- based division of …

The Liver-Derived Endocrine Hormone FGF21 Alters Metabolism and Diurnal Behavior via the Nervous System
… (cell body of vagus nerve), implicating roles in circadian and metabolic regulation. Results of surgical, pharmacological, and genetic strategies indicate the vagus senses circulating FGF21, resulting in adrenergic efferent responses that reduce insulin secretion, while a different adrenergic site …

Variação no padrão de atividade de mamíferos em resposta à sazonalidade em um parque nacional da floresta tropical seca brasileira
… of records, composition, simple occupancy and activity pattern of the species and their relationship with seasonality. We collected the data throughout the rainy and dry seasons of 2018, using camera traps at 44 and 40 sampling points, with an effort of 2267 and 1639 camera-days, respectively. …

An Evaluation of Bed Bug (Cimex lectularius L.) Host Location and Aggregation Behavior
… differences in behavior with regard to their circadian activities. Arena bioassays were conducted to determine the bed bug's ability to locate a host from different distances and if the antennae were essential for host location. Starved bed bugs were able to locate a host from 100 cm away. The …
