Nonlinear science has primarily developed from applications of mathema
tics to physics. The biological sciences are emerging as the dominant
growth points of science and technology, and biological systems are ch
aracterised by being information dense, spatially extended, organised
in interacting hierarchies, and rich in diversity. These characteristi
cs, linked with an increase in available computing power and accessibl
e memory, may lead to a nonlinear science of complicated interacting s
ystems that will link different types of mathematical object within a
framework of many-sorted algebras. Examples, drawn from current work o
n intracellular, cellular, tissue, organ and integrative physiology of
an individual, are outlined within the theory of synchronous concurre
nt algorithms. Possible directions in population dynamics and applicat
ions to ecosystem management are outlined. (C) 1997 The Franklin Insti
