In free-living animals, it has been well demonstrated that the intensity of the adrenocortical response to acute restraint stress can vary with reproductive investment during breeding. The parental care hypothesis posits that the stress response is negatively correlated with parental investment in avian species. To further test this hypothesis, we examined(More)
2D black phosphorus (BP) and rhenium dichalcogenides (ReX2 , X = S, Se) possess intrinsic in-plane anisotropic physical properties arising from their low crystal lattice symmetry, which has inspired their novel applications in electronics, photonics, and optoelectronics. Different from BP with poor environmental stability, ReX2 has low-symmetry distorted 1T(More)
Life-history theory assumes that the fitness costs of immunity may have negative effects on reproductive success. Similarly, the immunocompetence handicap hypothesis is based on findings that testosterone (T) has immunosuppressive effects, although the basis of this hypothesis has recently been challenged. As much of the work examining the relationship(More)
In vertebrates, myoglobin (Mb) and cytoglobin (Cygb) are closest relatives in the family of globins, which are heme-containing proteins that can bind gaseous molecules. Mb acts not only as an O2 transporter but also a nitric oxide (NO) scavenger in cardiac and striated muscle. Cygb has been suggested to play important functions in lipid-based signaling(More)
In birds, corticosterone (CORT), testosterone (T), and corticosteroid binding globulin (CBG) are involved in modulating the trade-off between reproduction and survival. In response to acute stress, increased total plasma CORT is a ubiquitous phenomenon while T levels can decrease, or remain unchanged. Since CORT and T bind competitively with CBG in birds,(More)
