Hygropreference and brood care in the honeybee (Apis mellifera).
Terrestrial organisms need to limit evaporation from their bodies in order to maintain a homeostatic water balance. Owing to a large surface to volume ratio, arthropods are particularly susceptible to desiccation and have evolved behavioural and physiological mechanisms to conserve water. In social insects, water balance is also affected by the interactions between nestmates and by the architec...

تمایل به ارزیابی جایگزین و تعویض آن با آزمون سنتی مداد و کاغذ در سالهای اخیر افزایش یافته است. اکثر زبان آموزان در کلاس های زبان از نمره نهایی که استاد تعیین میکند ناراضی اند. این تحقیق جهت بررسی ارزیابی در کلاس های زبان انگلیسی به هدف رضایتمندی زبان آموزان از نمره هایشان انجام گرفته است که در آن نمرات ارائه شده توسط سه گروه ارزیاب (ارزیابی خود دانشجو، همسالان واستاد) در مهارت های تولید (تکل...
15 صفحه اولHydrolases of Developing Worker Brood and Newly Emerged Worker of Apis Mellifera Carnica
Previously published data concerning honey bee metabolism, dealt mainly with adult specimens. In most cases, biochemical changes connected with the polyethism of Apis mellifera worker bees were described (Costa and Cruz-Landim, 2005; Elekonich and Roberts , 2005; Roberts and Elekonich, 2005). Little is known about the changes in the metabolism in successive developmental stages of brood (see Hr...

متن کاملDrone and Worker Brood Microclimates Are Regulated Differentially in Honey Bees, Apis mellifera
BACKGROUND Honey bee (Apis mellifera) drones and workers show differences in morphology, physiology, and behavior. Because the functions of drones are more related to colony reproduction, and those of workers relate to both survival and reproduction, we hypothesize that the microclimate for worker brood is more precisely regulated than that of drone brood. METHODOLOGY/PRINCIPAL FINDINGS We as...
