Reproduction is a process delicately choreographed to ensure the survival of species. In terms of precision and beauty, reproductive physiology is just as amazing as the flamboyant display of reproductive behaviors. Any misstep during the scripted development of functional gonads and gametes may result in reduced fertility or infertility. Fertility disorders in human are a major health problem ...

Microplastics are ubiquitous in aquatic ecosystems globally, with tropical freshwater systems underrepresented the literature. The ubiquity of microplastics may affect feeding, growth, reproduction, and survival organisms systems; however, data on potential effects is tentative. In current study, I conducted a meta-analysis using published to examine impacts microplastic exposure functional tra...

Being a prominent and profoundly prolific thinker, Abu Nasr al-Farabi is well-known in many spheres of sciences his time. In particular, he was interested the very nature human being origin. On Perfect State (Section IV. Man. Chapter 11-12), explains detail limbs organs body, as well ability reproduction. As thinker who carried out thorough analysis all areas research, while describing essence ...

This study addressed the effects of adding citrus peel (CP) and Ecklonia cava disuse extract (ECD) in diet abalones, which are a highly utilized marine species Korea. As interest abalone farming is increasing around fishing community, installation land tanks fish farms on southern coast Jeju Island South Korea spreading remarkably. In order to create best opportunities for survival reproduction...

Natural selection does not necessarily favor maximal reproduction because reproduction imposes fitness costs, reducing parental survival, and offspring quality. Here, we show that parents in a preindustrial population in North America incurred fitness costs from reproduction, and women incurred greater costs than men. We examined the survivorship and reproductive success (Darwinian fitness) of ...

AIDS TO PHYSIOLOGY.-By H. Dryerre, Ph.D., M.K.U.S., l.k.c.p. (Lond.), F.R.S.E. London: Bailliere, Tindall and Cox, 1931. Pp. vii plus 255, with 57 figures in the text. Price, 3s. 6d. net Aids to Physiology forms one of the Students' Aid Series. The object of this book, as stated in the preface, is to give the student a survey of the scope of physiology so that he can more profitably utilise the...

Extensive research confirms that abiotic stressors like predation risk can profoundly affect animal condition. However, there is a lack of experimental assessing the suite physiological responses to risk. We increased in free-living plateau pikas ( Ochotona curzoniae ) by simulating natural chases using model predator (UAV: unmanned aerial vehicle) and monitored behavior, physiology, reproducti...
