STREET CREATURES QUIZ

What is Street Creatures?  This is the game I run on Twitter every Friday. I’ve
collected all the past quizzes here in one place so you can either relive them, or play
them for the first time.

How does it work?  Provided are four, seemingly unrelated clues, that are all
connected by a wild organism that can be found in a city. Look at the four clues,
do some research, and when you think you’ve figured it out, click on ‘Answer’
to reveal what connects the clues, and how they are connected.

Follow me on Twitter to play #StreetCreatures live every Friday at 9am PST.

Quiz #2 Clues

Radioactive reindeer
British soldiers
Fragmentation
Model building

Answer (Don't click until you've solved it)

Cladonia sp. lichen

Radioactive reindeer:

After the Chernobyl explosion, caesium 137 levels in lichens were 165 times higher than previously recorded. The reindeer, of course, ate the lichens and it accumulated in their system, and entire herds had to be disposed of.

In fact, in 1988, 536 tons of contaminated reindeer meat had to be disposed of. The Saami people have suffered severely as a result and even today, the reindeer are still radioactive.
 

British Soldier:

The species Cladonia cristatella has a common name of British soldier, in the family Cladoniaceae.

Learn more about this species.

Fragmentation:

Cladonia species frequently spread by being fragmented. Reindeer actually play a role in that as they walk across and break pieces off the lichens.

Model Building:

Cladonia species are frequently used in model building – both on model railroads and also for architectural models. A fact I wish I’d known when I was in landscape architecture school!
