The book Mathematics for the Life Scientists (http://press.princeton.edu/titles/10298.html ) by Erin N. Bodine, Suzanne Lenhart & Louis J. Gross could be of some help.

The article linked below gives some further useful pointers (references to the books etc.) as far as mathematics is concerned.

The book "Mathematical Biology" by J. D. Murray

(two volumes)

I don't know of a book that cover both mathematics (?modelling) and statistics well, but would suggest:

Modeling the dynamics of Life, F R Adler.

and 

Intuitive Biostatistics, H Motulsky [the latter is associated with Graphpad Prism]
