Effects of photoperiod on growth of larvae and juveniles of the anemonefish Amphiprion melanopus [PDF]

, 2000
Rearing of anemonefishes is now relatively routine compared to the culture of cardinalfishes (Apogonidae) or angelfishes (Pomacanthidae). However, it is still a labor intensive, time intensive and expensive procedure.

A PERIOD3 variant causes a circadian phenotype and is associated with a seasonal mood trait. [PDF]

, 2016
In humans, the connection between sleep and mood has long been recognized, although direct molecular evidence is lacking. We identified two rare variants in the circadian clock gene PERIOD3 (PER3-P415A/H417R) in humans with familial advanced sleep phase ...

Exogenous Melatonin Improves the Tibial Performance, Morphology and Metabolism Balance in Rapid Bone Growth Phase of Long Photoperiod Broilers

Agriculture
Bone metabolism dynamic balance is pivotal to bone formation in broilers. Long photoperiods have resulted in leg bones disorders in broilers. Melatonin (MT) is an essential hormone that protects the growth and development of bones, but the functions of ...

Quantitative analysis of regulatory flexibility under changing environmental conditions [PDF]

, 2010
The circadian clock controls 24-h rhythms in many biological processes, allowing appropriate timing of biological rhythms relative to dawn and dusk. Known clock circuits include multiple, interlocked feedback loops.

Photoperiod influences visceral adiposity and the adipose molecular clock independent of temperature in wild‐derived Peromyscus leucopus

FASEB BioAdvances
Physiology is closely synchronized to daily and seasonal light/dark cycles. Humans artificially extend daylight and experience irregular light schedules, resulting in dysregulation of metabolism and body mass. In rodents, winter‐like conditions (cold and

Effects of Continuous and Split Developmental Photophases During Each 24 Hour Period on Adult Color and Pubescence in \u3ci\u3eThyanta Calceata\u3c/i\u3e (Hemiptera: Pentatomidae) [PDF]

, 2017
Rearing immatures of Thyanta calceata in SL: 16D, SL:4D:8L:4D, and 16L:8D photo- periods showed that the length of each photophase, rather than an accumulation of shorter photophases, during each 24 h period wa, the determining factor in producing adult ...

CONSTANS is a photoperiod regulated activator of flowering in sorghum

BMC Plant Biology, 2014
BackgroundSorghum genotypes used for grain production in temperate regions are photoperiod insensitive and flower early avoiding adverse environments during the reproductive phase. In contrast, energy sorghum hybrids are highly photoperiod sensitive with

Investigating Social Immunity in Swarming Locusts via a Triple Animal–Robot–Pathogen Hybrid Interaction

Advanced Intelligent Systems, EarlyView.
This study explores social immunity in gregarious locusts using a groundbreaking animal–robot–pathogen interaction model. By comparing locust responses to biomimetic agents mimicking healthy and infected individuals, significant behavioral changes are revealed.

Agronomic evaluation of Paspalum notatum Flügge under the influence of photoperiod

Revista Brasileira de Zootecnia
The objective of this study was to evaluate the influence of photoperiod on the forage yield by ecotypes and intraspecific hybrids of P. notatum. Tetraploid ecotypes from the United States Department of Agriculture and the National University of the ...

Effects of Various Photoperiods on Color and Pubescence in \u3ci\u3eThyanta Pallidovirens Accerra\u3c/i\u3e (Hemiptera: Pentatomidae) [PDF]

, 2017
The effects of a range of developmental photoperiods on adult dimorphism in Thyanta pallidovirens accerra were studied under laboratory conditions. Adults reared in photo- phases of 14L and higher had short pubescence and those in 12L and lower, long pu-
