The man/woman they want doesn't exist. If they did, they could do a lot better than that job...they might even become a blogger.
The biology shit they outlined, plus the degrees, would qualify that person for a full professorship or plenty of research grants. Why would that person want to be their Biodiversity Information Manager cum IT guru/programmer?
Sounds to me like the information is already in disparate data bases and they want it available easily....all of it. This is an IT job, pure and simple.
That said, it sounds like they would want you're home number and your cell number. A full time plus, kind of job.
