摘要:The effect of experience on the behavior of worker bees has been extensively investigated; however, few such studies have been conducted on male bees. Honeybee ( Apis mellifera ) males (drones), unlike the males of other social hymenopterans, return to their nest after perfo...

摘要:Abstract(#br)During reproduction, ant colonies produce winged queens. These new queens usually leave the nest to mate and can then establish a new nest. If the new nest is close to an existing colony, it will be in competition with the existing colony. Therefore, workers wil...

摘要:Abstract(#br)In some species, a brood hatches or is born asynchronously over an extended period of time. This asynchronous hatching establishes competitive asymmetries between offspring, and younger offspring usually exhibit a higher mortality risk and/or lower growth rate. A lar...

摘要:Abstract(#br)Parental care requires a large investment of time and energy. This can reduce future parental survival and opportunities for mating. Because males are usually more uncertain of their parentage with respect to the caring of offspring than are females, the reduction in...

摘要:Abstract(#br)Despite decades of intensive research, there is still much debate about the adaptive significance of asynchronous hatching. A major obstacle in understanding the significance of this process is the difficulty involved in separating the hypotheses that explain asynchr...

摘要:Abstract(#br)The need to understand the mechanisms enhancing species coexistence and diversity is one of the central issues of community ecology. Theoretical work suggests that resource partitioning based on body size contributes to the coexistence of competing species, resu...

摘要:Summary(#br)Parental care is a notable aspect of reproductive effort in many animals. The interaction between offspring begging and the parental feeding response is an important communication mechanism that regulates offspring food supply, and reducing the cost of superfluou...

摘要:A novel dsRNA virus was identified from the arboreal ant Camponotus yamaokai . The complete nucleotide sequence analysis of the virus revealed that the virus consisted of 5704 bp with two ORFs. ORF1 (3084 nt) encoded a putative capsid protein. ORF2 (1977 nt) encoded a viral ...

摘要:The analogy between the inversely normalized frequency in electrohydro-dynamics (EHD) and the Prandtl number in a convective flow was studied by measuring the relaxation process observed in the intensity of light transmitted. It is obtained in EHD that the Prandtl number is about...
