Abstract In addition to resource value, the cost of finding mates may affect how much males invest in fights for females. The females be imposed through natural factors extrinsic males, such as female spatial distribution and predation pressure, which can challenging simulate laboratory conditions. Therefore, studies under conditions suitable understanding costs mating partners male investment ...

In most fish species there is a great size range of reproductive males, setting the stage for divergent, intraspecific reproductive patt...

BACKGROUND AND AIMS Frost tolerance of wheat depends primarily upon a strong vernalization requirement, delaying the transition to the reproductive phase. The aim of the present study was to learn how saturation of the vernalization requirement and apical development stage are related to frost tolerance in wheat. METHODS 'Mironovskaya 808', a winter variety with a long vernalization requireme...
