The message
from "michael adams" contains these words:

While given that they had no predators at all until the arrival
of the motor car

You're mistaken. Both badgers and foxes can unroll, kill and eat
hedgehogs and I've seen dogs do it too. Birds of prey here are often
seen eating roadkill hedgehogs.



So, they are not "the end of their own
food chain" either..whatever that means!

Janet.

Badgers, foxes, and birds of prey can catch things by eating
hedgehogs then.

And unless anything eats them in turn then they're the end of
their own food chain.

The food chain stretches from the first thing to be eaten - a wheat
grain say - which could carry an infectious pathogen - all the way
through to the highest order organism which isn't itself a food
source. Quite often homo sapiens.

That's the general idea anyway.

You were going so well up until that point as well.
