Information about “BSIM”
College and high school Biology instructors -- You will find BSIM
especially interesting. In classrooms equipped with PCs, BSIM can
create simulated ecological systems to be used as models of actual
biological systems. The program provides fun reinforcement of the
basic subject matter covered in class and encourages the mental
manipulation of conceptual elements well beyond standard
calculation-phase gymnastics. The model for the program is an aquatic
ecosystem,
but the general features can be applied across a broad range of other
ecosystems.
Sample stagnant and circulated flask environments, leave open or
closed to oxygen and carbon-dioxide atmospheres, choose light or dark,
depth, and choice of sample location according to a grid. Temperature
and pH are assumed constant and optimum. Also available is a readout
of solution elements for the sample taken.
"Pseudogenomes" are projections of real organisms, complete with
physical structures and processes determined by 13 changeable elements
set by the user. Organisms feed and grow, using a simplified carbon
chemistry. They are capable of reproduction or reduction with
sampling possible at each generation. BSIM allows for new organisms or
the "reseeding" of old ones at first generation. BSIM has a simple
printer facility and easy menus.
The registration fee provides the user with technical data and program
utilities to assist program analysis, and an experimenter's manual for
ten experiments. These experiments cover sampling techniques,

BSIM is a computer simulation which generates a 'pseudo- ecology' that
can serve as an analog for actual biological systems. The program
generates organisms as a function of a simulated genome which specifies
the rules whereby the organisms will interact with a specified physical
environment. The model for the program is a microbial aquatic
ecosystem, but many of the features of the system are more general and
it can be used to conceptualize a broader range of natural ecosystems.
A simplified biochemical and physiological model is used to
characterize the organisms based on a 13 element, mutable genome. The
user has broad control over the starting conditions, both of the
environment and of the 'seed' organisms. Sampling options permit
following the development of the population in great detail as it
responds to a dynamically changing environment with various forms
evolving and disappearing with time. Concepts of population dynamics
(including mutualism, commensalism, competitive exclusion, and
parasitism), mass flow in ecosystems, and evolution are readily
demonstrated. Realistic experiments can be performed which closely
parallel those often done in actual laboratory and field settings. Many
of the analytical reasoning techniques applied in general data analysis
can be used to elucidate the features of the various model organisms
which arise in the simulation and the lessons learned are directly
applicable to laboratory and field investigations.

BSIM is a program that college and high school biology instructors will
find especially interesting. For classrooms with PCs, BSIM can simulate
pseudoecological systems to be used as analogs to actual biological
systems. The model for the program is an aquatic ecosystem, but it is
intended that generalized features of this ecosystem be used to
conceptualize a broader range of ecosystems.
Providing basic subject matter is covered in class, the program provides
fun, illustrative learning reinforcement, and encourages mental
manipulation of conceptual elements well beyond calculation-phase
minutes. The $29.95 registration fee will net the user technical data
and program utilities to assist program analysis, and an experimenter's
manual for ten experiments.
BSIM allows sampling of stagnant and circulated flask environments open
or closed to oxygen and carbon-dioxide atmospheres, choice of light and
dark, depth, and choice of sample location according to grid.
Apparently, temperature and Ph are assumed constant and optimum.
Essentially, "pseudogenomes" are intended to be abstractions of real
organisms with morphology and physiology determined by 13 "mutable"
pseudogenome elements which can be set by the user. Organism metabolism
is intended to utilize a simplified carbon chemistry, and the organisms
are apparently capable of reproduction or reduction with sampling
possible at each generation. The program allows for new organisms or
"reseeding" of old ones at first generation, and a readout of solution
elements for the sample taken.
BSIM has a simple printer facility and easy menus.
System Requirements: CGA, EGA, HGA adaptor.
