Incubation temperature affects multiple measures of immunocompetence in young wood ducks (Aix Sponsa).
Parental effects play a vital role in shaping offspring phenotype. In birds, incubation behaviour is a critical parental effect because it influences the early developmental environment and can therefore have lifelong consequences for offspring phenotype. Recent studies that manipulated incubation temperature found effects on hatchling body composition, condition and growth, suggesting that inc...
متن کاملWarm Is Better: Incubation Temperature Influences Apparent Survival and Recruitment of Wood Ducks (Aix sponsa)
Avian parents that physically incubate their eggs must balance demands of self-maintenance with providing the proper thermal environment for egg development. Low incubation temperatures can lengthen the incubation period and produce changes in neonate phenotype that may influence subsequent survival and reproduction. We artificially incubated wood duck (Aix sponsa) eggs at three temperature reg...
متن کاملIncubation temperature influences locomotor performance in young wood ducks (Aix sponsa).
Incubation temperature is an important maternal effect in birds that can influence numerous offspring traits. For example, ducklings from eggs incubated at lower temperatures have lower growth rates, protein content, and are in poorer body condition than ducklings from eggs incubated at higher temperatures. Based on these observations, we predicted that incubation temperature would indirectly i...
متن کاملFitness consequences of delayed maturity in female wood ducks
Age at maturity has been suggested to be an important life-history trait with substantial potential for influencing the evolution of life histories. Using known reproductive histories of 90 female wood ducks (Aix sponsa) from a long-term study (1982–96), we investigated the fitness consequences of changes in age at maturity. Female wood ducks that attained sexual maturity as yearlings had a sig...
متن کاملEarly onset radiation induced sarcoma of scalp: A case report
Radiation induced sarcoma is a rare but recognized complication of radiotherapy and is associated with poor prognosis, frequently occurs 5 years after completion of treatment. We report radiation-induced sarcoma in a 42 years old male, involving the left parietooccipital scalp region following treatment of brain tumor with craniotomy and post-operative radiation with 60Co machine. Diagnosis of ...
