Facultative social parasitism in the allodapine bee Macrogalea berentyensis

引用

Insect Science 2007年第1期14卷 65-69页

作者： JACLYN A. SMITH School of Biological Sciences Flinders University Adelaide South Australia Australia

Previous research on social parasitism has largely ignored allodapine social parasites, which is surprising given the huge potential of these bees to provide a better understanding of social parasitism. Macrogalea berentyensis, a species that was previously suggested to be a social parasite, was collected in nests of M. ellioti, and also in nests consisting of only M. berentyensis. These f＇mdings, along with morphological and phylogenetic evidence, show that this species is a facultative social parasite. In the independently living M. berentyensis nests, brood were present that had been reared to an advanced stage, suggesting that：（i） these parasites may be effective at foraging and caring for their brood; or （ii） these nests may be colonies where all the hosts had died, and these parasites had yet to disperse. Macrogalea berentyensis is the closest relative of the facultative social parasite, M. antanosy, and both these species represent the most recent evolutionary origin of social parasitism within the allodapines. Further behavioral research on both these parasitic species would therefore have important implications for the understanding of the evolution of social parasitism.

Endogenous testosterone and mortality risk

引用

Asian Journal of Andrology 2018年第2期20卷 115-119页

作者： Emily J Meye Gary Wittert Endocrine Diabetes and Metabolic Unit Royal Adelaide Hospital Port Road SA 5000 Australia Discipline of Medicine University of Adelaide Adelaide SA 5000 Australia Discipline of Medicine and Freemasons Foundation Centre for Men's Health University of Adelaide SA 5000 Australia

In men, obesity and metabolic complications are associated with lower serum testosterone （T） and dihydrotestosterone （DHT） and an increased risk of, and mortality from, multiple chronic diseases in addition to cardiovascular disease （CVD）. The causal interrelationships between these factors remain a matter of debate. In men with untreated congenital and lifelong forms of hypogonadotropic hypogonadism, there appears to be no increased risk. Men with Klinefelter＇s syndrome have an increased risk of various types of cancers, as well as CVD, which persist despite T therapy. In the absence of pathology of the hypothalamic-pituitary- gonadal axis, the effect of modest reductions in serum T in aging men is unclear. The prevalence of low serum T concentrations is high in men with cancer, renal disease, and respiratory disease and is likely to be an indicator of severity of systemic disease, not hypogonadism. Some population-based studies have found low serum T to be associated with a higher risk of deaths attributed to cancer, renal disease, and respiratory disease, while others have not. Although a meta-analysis of longitudinal studies has shown an association between low serum T and all-cause mortality, marked heterogeneity between studies limited a firm conclusion. Therefore, while a decrease in T particularly occurring later in life may be associated with an increase in all-cause and specific types of mortality in men, the differential effects, if any, of T and other sex steroids as compared to health and lifestyle factors are unknown at the current time.
