Lek , northern arm of the Rhine River, 40 mi (64 km) long, branching from the Neder Rijn (Lower Rhine), central Netherlands, and flowing W into the Nieuwe Maas (New Meuse) River. It is navigable for its entire length. Rotterdam , the chief city on the river, is connected with the North Sea by the Nieuwe Waterweg (canal).

lek A territory that is held and defended against rivals by males of certain species during the breeding season. The male displays within its lek in order to attract females into the lek for mating. Females move among the leks, mating with males to whose displays they respond. Consequently, for a local population of a species, leks are usually grouped together within a breeding area and dominant males tend to occupy the more central leks, where their displays can be seen by the largest number of females.
