officinale are autonomous gametophytic apomicts, meaning that embryo sacs develop from unreduced megaspores and both endosperm and embryo are pro- duced without fertilization (Grimanelli et al., 2001). T. officinale in Europe and Asia exhibit the common pattern of geographical parthenogenesis in ...
In Sex, Murder, and the Meaning of Life, social psychologist Douglas Kenrick exposes the selfish animalistic underside of human nature, and shows how it is intimately connected to our greatest and most selfless achievements. Masterfully integrating cognitive science, evolutionary psychology, and complexi...
Such terms convey balanced genetic polymorphism maintained by negative little precise meaning and it seems reasonable to consider frequency-dependent selection mediated by disas- other adaptive explanations that focus equally on both sortative mating. It seems likely that, in common with female and male...
al. (2007) showed that biparental clutch desertion is an outcome of the intense sexual conflict between males and females. Deserting parents often remate and renest, and thus, both males and females are sequentially polygamous within a single breeding season. Traits involved in mate choice and ...
Termination of fire along with active removal of deciduous trees in favor of confiers together with anthropogenic transformation of productive forest into agricultural land, have transformed northern European coniferous forests and reduced their deciduous component. Locally, however, in the villages, deciduo...

Pseudo-nitzschia species are generally heterothallic, meaning they require another mating type (e.g. PNp+ or PNp−) for sexual reproduction. Many sexual reproduction studies have been conducted using this genus to exam- ine diatom reproduction and life c ycles22–24,33,45, yet there ...
(Lau,1981). In China, employees generally work for the sake of their families, such that the meaning of work is inherently tied to that of family (Yang et al.,2000). Recent research has shown that a desire to work for the benefit of one’s family motivates employees to work hard (...
