Most models of population dynamics do not take sexual reproduction into account (i.e. they do not consider the role of males). However, assumptions behind this practice-that no demographic sex differences exist and males are always abundant enough to fertilize all the females-are usually not jus...
chloronotus is important to maintain local population sizes, but that larval exchange between populations mediated by sexual reproduction is important for colonisation of new areas and to provide connectivity between populations. Here, we present the first synthesis of these phenomena for a holothurian ...
The growth,development,and sexual reproduction of Sargassum thunbergii were studied in Qingdao,Shandong Peninsula,China,in the spring and summer of 2006 by indoor cultivating and observing on the local tidal sites. The results showed that both the growth in algal length and receptacle development depe...

Sexual reproduction and larval settlement of Alveopora japonica Eguchi were studied at its northernmost distribution in Tokyo Bay (34°58′03′′N, 139°46′05′′E), where the annual sea temperature ranges from 13 to 27°C. Alveopora japonica is a hermaphroditic brooding coral with oocytes and...

Whether describing a 62-year-old man having a major heart attack (and how his myocardial cells rupture and die), or discussing curious life-forms that defy any definition of life (including bacterial spores, which can regenerate after decades of inactivity, and viruses, which are nothing more ...
