Because the same MF hormone affects a broad range of crustaceans, any insecticide that mimics MF also may affect a large number of species in freshwater communities.

Breeding studies with both males and females often are necessary to identify candidate genes responsible for certain genetic traits. If we want to understand, for example, the genetic basis for why some clones of Daphnia from lakes are more resistant to pollution, then having males could help to find the genes in the genome.

Liverpool really ever since I can remember, but anyway in the '50s and '60s was always a place where people were potentially in show business, knew someone who was, would like to be, had been but were now doing something else and there was a general recreational feeling in the air at all times.

Well the seaport, all seaports in Britain whether it's Glasgow or Newcastle or... or Liverpool, any of the seaports, I've got this kind of knock about, beggar and the Lord will provide feeling about it.

I think there's always been a myth that sailors brought in records in their knapsacks as if you could ... in the local shops. I think that maybe some songs did come in with the sailors and maybe they did whistle some of the things in the streets in sharp ears because.

The docks were said to be quite tough, but there were pubs you didn't go into if you were a respectable... but um, I never felt a sense of danger in Liverpool.

Not part of any London combination and you have to go a long way from London really to... to throw that feeling off. So, it's right and fitting that the Beatles came from Liverpool. If they hadn't, I wouldn't have got involved. It wouldn't have interested me. And they wouldn't have hired me.

Brian Epstein was like all people who turn out to be of interest, someone who was of interest to himself. I hear this a lot now. There's a feeling of I am different.

Nobody knows I'm different. Or they may know, but they don't know how different and they don't know what this thing is that's driving me because I can't... this is... these are charges ... which I understand having got two children of my own and having had these mad thoughts myself that you know, I've got to get out there and do something. I don't know what it is, but it's got to be interesting.

We need to know the species identities in order to understand how freshwater communities are changing over time, as a response to climate change, pollution or invasive species. We're hoping that by studying the biology of the rare males, we can learn more about species diversity and freshwater ecosystem changes.
