Sex-biased phoretic mite load on two seaweed flies: Coelopa frigida and Coelopa pilipes.
Two hypotheses explain male-biased parasitism. Physiological costs of male sexually selected characteristics can reduce immunocompetence. Alternatively, ecological differences could generate male-biased parasitism. One method of comparing the importance of the two theories is to investigate patterns of phoresy, which are only likely to be generated by ecological rather than immunological differ...

تجارت الکترونیکی شیوه اجرای مسئولیتها، تقابل با مشتریان و امور معمول عملیاتی در شرکتها را تغییر داده است. تجارت الکترونیکی در عمل تنها خرید و فروش کالاها را از طریق ابزار الکترونیک نمی باشد، بلکه تمام فعالیتهای لازم جهت انجام فرایند فروش را نیز در بر میگیرد. در اواخر دهه 1990 بسیاری از شرکتها فعالیتهای خود را به منظور دستیابی به مشتریان جدید و یا ارائه فرصتهای جدید به مشتریان موجود گسترش دادند...
Environmental enrichment improves mating success in fruit flies
Environmental enrichment, defined as housing conditions that include a combination of complex inanimate and social stimulation, has strong positive effects on brain and behaviour in various species. We extended previous studies to evaluate how enrichment affects mating success. In a series of experiments, we found that male fruit flies, Drosophila melanogaster, reared in an enriched environment...
متن کاملMating Reverses Actuarial Aging in Female Queensland Fruit Flies
Animals that have a long pre-reproductive adult stage often employ mechanisms that minimize aging over this period in order to preserve reproductive lifespan. In a remarkable exception, one tephritid fruit fly exhibits substantial pre-reproductive aging but then mitigates this aging during a diet-dependent transition to the reproductive stage, after which life expectancy matches that of newly e...
متن کاملEvolution of female mating preferences in stalk-eyed flies
Sensory exploitation predicts that female mate preferences exist before the evolution of exaggerated male ornaments. We tested this prediction by estimating female preference functions, remating intervals, and copulation durations for three species of stalk-eyed flies. Two species, Cyrtodiopsis whitei and C dahnanni, exhibit extreme sexual dimorphism in eye span, with eye stalks exceeding body ...
