the questions/complete the sentences that

follow:

Sniffer dog Tucker uses his nose to help

researchers find out why a killer whale

population off the northwest coast of the

United States is on the decline. He searches

for whale faeces floating on the surface of

the water, which are then collected for

examination. He is one of the elite team of

detection dogs used by scientists studying a

number of species including right whales and

Killer whales. Conservation canines are fast

becoming indispensable tools for biologists

according to Aimee Hurt, associate director

and co-founder of Working Dogs for

Conservation, based in Three Forks, Montana.

Over the last few years, though, so many new

conservation dog projects have sprung up that

Hurt can no longer keep track of them all. Her

organization's dogs and their handlers are

fully booked to assist field researchers into

2012.

Dogs have such a phenomenal sense of smell",

explained Sam Wasser, director of the Center

for Conservation biology at the University of

Washington in Seattle. He has worked with

scat-detection dogs since 199(g). Scientists

have been using Conservation Canines in their

research since 199(g). These dogs have enabled

them to non-invasively access vast amount of

genetic and physiological information which is

used to tackle conservation problems around

the world. Such information has proved vital
