Carotenoid availability in diet and phenotype of blue and great tit nestlings.
Carotenoids are biologically active pigments of crucial importance for the development of avian embryos and nestlings. Thus parental ability to provide nestlings with a carotenoid-rich diet may enhance offspring fitness. However, very little is known about the possible effects of carotenoid availability in the diet on growing nestlings in natural populations. We experimentally manipulated dieta...
متن کاملSpatial and Temporal Variation of Lead, Cadmium, and Zinc in Feathers of Great Tit and Blue Tit Nestlings in Central Poland
In this study, we examined heavy-metal concentrations in feathers of nestling great tits Parus major and blue tits Cyanistes caeruleus at two different sites (urban parkland vs. deciduous forest) located in the Łódź agglomeration in relation to interyear variation. We found that tit species did not differ significantly in lead and cadmium concentrations. Zinc concentration was significantly hig...
متن کاملAssociation between Enuresis and Body Mass Index in Schoolchildren
BackgroundAutomatic release of urine at any time of a day during sleep beyond the age of five years defined enuresis as a health disorders in children. The etiology of enuresis is still not clearly understood. Body Mass Index (BMI) is an indicator to evaluate the growth trend of individuals in a population for any specific age group. Evaluation of obesity in children is important and provides a...
متن کاملLow Cross-Sex Genetic Correlation in Carotenoid-Based Plumage Traits in the Blue Tit Nestlings (Cyanistes caeruleus)
In some bird species, both adult and juvenile individuals are often brightly coloured. It has been commonly assumed that identical plumage colouration present in both sexes results from strong intersexual genetic correlations in colour-related traits. Here, we aimed at testing this hypothesis in juvenile individuals and looked at genetic parameters describing carotenoid-based colouration of blu...
متن کاملRelationships between body mass index, fat mass, muscle mass, and musculoskeletal pain in community residents.
OBJECTIVE To evaluate the relationships between fat mass, muscle mass, fat:muscle mass ratio, metabolic syndrome, and musculoskeletal pain in community residents. METHODS In the Korean Health and Genome Study, 1,530 participants (mean ± SD age 60.8 ± 8.60 years) completed pain questionnaires and underwent dual x-ray absorptiometry to calculate body composition. Pain was categorized according ...
