Phytovolatilization

Plants remove inorganic contaminants· either by contaminant volatilization or by metal accumulation.

Volatalization is useful for the removal of mercury. A bacterial mercuric ion reductase has been transferred to Arabidopsis thaliana; this transgenic plant absorbs mercury, and reduces it to volatile Hg0, which volatilizes from the leaf surface.

Polygynous

In polygyny, one male mates with more than one female in a single breeding season, but females mate only with one male.

In species with male-male competition, males are often substantially larger than females, a phenomenon called sexual dimorphism.
