If you are interested in learning more and furthering your grasp of
Calculus and Mathematical Biology, the following are some additional
noteworthy resources:

Introduction
to Mathematics for Life Scientists by E. Batschelet.
This book is a more serious/demanding textbook and an excellent resource,
despite the fact it was written in 1972. The choice of topics,
sequence of presentation, level of detail, use of examples, and clarity
and elegance of exposition are all outstanding.

Mathematical Biology: I. An Introduction (Part 1)
by James D. Murray.
The Bulletin of Mathematical Biology SIAM, 2004, says:
"Murray's Mathematical Biology
is a classic that belongs on the shelf of any serious student or researcher
in the field. Together the two volumes contain well over 1000 references,
a rich source of material, together with an excellent index to help readers
quickly find key words. [...] I recommend the new and expanded third edition
to any serious young student interested in mathematical biology who already
has a solid basis in applied mathematics."

Mathematical Models in Biology
by L. EdelsteinKeshet.

Modeling Differential
Equations in Biology by C. H. Taubes.

Population Ecology
by J. H. Vandermeer and D. E. Goldberg.
