Spring Landscapes

Most living things are tied into the rhythm of the seasons, whether they live in the Northern or Southern Hemisphere or even right on the equator, where cyles of moisture tend to dominate more than insolation. Spring, of course, is a time of rebirth and rapid growth, as this placid scene at the Chicago Botanical Garden suggests. Spring brings a dizzing assortment of flowers and active animals, each filling its own ecological niche.
