Balancing personal maintenance with parental investment in a chick-rearing seabird: physiological indicators change with foraging conditions
Seabird parents use a conservative breeding strategy that favours long-term survival over intensive parental investment, particularly under harsh conditions. Here, we examine whether variation in several physiological indicators reflects the balance between parental investment and survival in common murres (Uria aalge) under a wide range of foraging conditions. Blood samples were taken from adu...
متن کاملSeasonal Variation in Parental Care Drives Sex-Specific Foraging by a Monomorphic Seabird
Evidence of sex-specific foraging in monomorphic seabirds is increasing though the underlying mechanisms remain poorly understood. We investigate differential parental care as a mechanism for sex-specific foraging in monomorphic Common Murres (Uria aalge), where the male parent alone provisions the chick after colony departure. Using a combination of geolocation-immersion loggers and stable iso...

A Comparison of Perceived Parental Rearing Styles and Early Maladaptive Schemas in Students with Social Anxiety and Normal Students
The present study set out to compare perceived parental rearing styles and maladaptive schemas in students with social anxiety and normal students. The statistical population of the study was comprised of all female students studying in senior high schools in Baharestan County (Tehran Province) in 2013-14 academic year. Cluster sampling method was used and 140 students were selected via Social ...
متن کاملFeather corticosterone of a nestling seabird reveals consequences of sex-specific parental investment.
Offspring of long-lived species should face costs of parental trade-offs that vary with overall energetic demands encountered by parents during breeding. If sex differences exist in how parents make the trade-off, sex-specific differences may exist in the contribution of each parent to those costs. Adaptations of offspring facing such costs are not well understood, but the hormone corticosteron...
