Sexual signals reflect telomere dynamics in a wild bird
Telomere dynamics in natural populations have been linked to survival, reproduction, and energetic investment. Given their putative role in mediating life-history trade-offs, telomeres are also a likely candidate for maintaining honesty in sexually selected signals; few studies to date, however, have demonstrated a correlation between sexual signals and telomere dynamics. Here, we show that plu...
متن کاملthe relationship between language and social capital in ilami kurdish: a sociopragmatic approach
چکیده زبان به عنوان یک وسیله در ایجاد و بازسازی سرمایه اجتماعی در چند دهه گذشته مورد توجه بوده است. اگر چه درباره سرمایه اجتماعی و سازه های مربوط به آن زیاد نوشته شده است ولی خیلی کم بر روی اینکه چطور زبان می تواند باعث ایجاد اعتماد یا بی اعتمادی بشود مطالعه ای انجام شده است. این مطالعه به منظور تحقق دو هدف انجام گرفته است. اول تلاش خواهد شد تا یک گونه شناسی از واژگانی که مردم کرد زبان شهر ا...
15 صفحه اولInheritance of Telomere Length in a Bird
Telomere dynamics are intensively studied in human ageing research and epidemiology, with many correlations reported between telomere length and age-related diseases, cancer and death. While telomere length is influenced by environmental factors there is also good evidence for a strong heritable component. In human, the mode of telomere length inheritance appears to be paternal and telomere len...
متن کاملReverse sex-biased philopatry in a cooperative bird: genetic consequences and a social cause.
The genetic structure of a group or population of organisms can profoundly influence the potential for inbreeding and, through this, can affect both dispersal strategies and mating systems. We used estimates of genetic relatedness as well as likelihood-based methods to reconstruct social group composition and examine sex biases in dispersal in a Costa Rican population of white-throated magpie-j...
متن کاملTelomere length and dynamics predict mortality in a wild longitudinal study.
Explaining variation in life expectancy between individuals of the same age is fundamental to our understanding of population ecology and life history evolution. Variation in the length and rate of loss of the protective telomere chromosome caps has been linked to cellular lifespan. Yet, the extent to which telomere length and dynamics predict organismal lifespan in nature is still contentious....
