Perinatal Androgens and Adult Behavior Vary with Nestling Social System in Siblicidal Boobies

BACKGROUND Exposure to androgens early in development, while activating adaptive aggressive behavior, may also exert long-lasting effects on non-target components of phenotype. Here we compare these organizational effects of perinatal androgens in closely related Nazca (Sula granti) and blue-footed (S. nebouxii) boobies that differ in neonatal social system. The older of two Nazca booby hatchli...

Excess offspring as a maternal strategy: constraints in the shared nursery of a giant damselfly

Maternal reproductive strategies should optimize the quality and quantity of surviving offspring. In Megaloprepus caerulatus, a damselfly that exhibits male-biased size dimorphism, larval siblicide, and a disproportionate fitness advantage from large sons, mothers lay many more eggs in water-filled tree holes than can survive to emergence. Using field experiments, I tested the siblicide advanta...

Foot-mediated incubation: Nazca booby (Sula granti) feet as surrogate brood patches.

Incubation in most avian species involves transferring heat from parent to egg through a highly vascularized brood patch. Some birds, however, do not develop a brood patch. Unusual among birds, these species hold their eggs under the webs of their feet, but the role of the feet in heat transfer is uncertain. Often the webs are positioned between the feathered abdomen and the egg during incubati...

Biochemical and histological studies of over-ripened oocyte in the Caspian brown trout (Salmo trutta caspius) to determine biomarkers for egg quality

  The aims of the present study were to determine the best time for egg stripping after ovulation and to study oocyte over-ripening in the Caspian brown trout (Salmo trutta caspius). Eggs were retained in the female abdominal cavity for 40 days post ovulation (DPO). Partial volumes of eggs stripped from 10 individually identified females at 10 days intervals and fertilized with a pool of semen ...

Nonsiblicidal behavior and the evolution of clutch size in bethylid wasps.

Parent-offspring conflict over clutch size may lead to siblicidal behavior between juveniles. In parasitoid wasps, selection for siblicide in small broods is predicted to produce a dearth of gregarious broods with few eggs. Here we document the clutch size distribution in the Bethylidae, a large family of aculeate parasitoids. Small gregarious clutches are the most common. Further data suggest ...
