Aerial view of the North Branch of the Chicago River, from the south, with Goose Island, near center. Early settlers named the North Branch of the Chicago River the Guarie River, or Gary's River, after a trader who may have settled the west bank of the river a short distance north of Wolf Point, at what is now Fulton Street.
Major ports on the Great Lakes Waterway include Duluth-Superior, Chicago, Detroit, Toledo, Cleveland, Two Harbors, Hamilton and Thunder Bay. [4] Shipping channels separate upbound traffic from downbound traffic. The upbound direction is away from the St. Lawrence River (westerly or northerly except in Lake Michigan where upbound is southerly).
When standing among trees and bushes, they are hard to see at even a few metres distance. However, adult giraffes move about to gain the best view of an approaching predator, relying on their size and ability to defend themselves rather than on camouflage, which may be more important for calves. [6] Each giraffe has a unique coat pattern.
The current IUCN taxonomic scheme lists one species of giraffe with the name G. camelopardalis and nine subspecies. [1] [7] A 2021 whole genome sequencing study suggests the northern giraffe as a separate species, and postulates the existence of three distinct subspecies, [8] and more recently, one extinct subspecies.
The Chicago Harbor Lock, also known as the Chicago River & Harbor Controlling Works, is a stop lock and dam located within the Chicago Harbor in Chicago, Illinois at the mouth of the Chicago River. It is a component of the Chicago Area Waterway System , and is used to control water diversion from Lake Michigan into the river and for navigation.
Reinforcement is the deliberate introduction and integration of an organism into an area where its species is already established. [1] This mode of translocation is implemented in populations whose numbers have dropped below critical levels, become dangerously inbred, or who need artificial immigration to maintain genetic diversity. [15]
The main area is divided into two sections, the northern section containing giraffes and gazelles, and the southern section being home to zebras and rhinos. Lions have their own enclosure, as do the mandrills. red river hogs and colobus monkeys share a home, and the African crested porcupines and Aldabra giant tortoise also live together. [4] [13]
The North Shore Channel is a 7.7 mile long canal built between 1907 and 1910 to increase the flow of North Branch of the Chicago River so that it would empty into the South Branch and the Chicago Sanitary and Ship Canal. [1] Its water is generally taken from Lake Michigan to flow into the canal at Wilmette Harbor.
