We've been running a captive-breeding programme with the boreal toad ( Bufo boreas ) since 1995,

Real estate is running really slow right now, and we're probably going to see that stall for a while.

Many species can't be bred in captivity,

We've tried re-introducing them to the wild seven or eight times, but every time they die within a couple of years; if you don't get rid of the fungus, all you're doing is providing it with lunch.

You can give them the right habitat and food, but they may need specific light or heat or moisture or group size, otherwise the female won't ovulate - and it can take years to study that.

Well, they keep me running all the time, but that particular year, they kept us running a little more than normal.
