INNATE BEHAVIORS
BEHAVIORS THAT ARE INHERITED = EGG EJECTION BY CUCKOOS
AND, A FEW WEEKS LATER ...
LEARNED BEHAVIORS OCCUR THROUGH INTERACTIONS W/ENVIRONMENT & OTHERS
BEHAVIORS ARE TRIGGERED BY ENVIRONMENTAL CUES, IE ESTIVATION

COOPERATIVE BEHAVIOR WITHIN OR BETWEEN POPULATIONS
CONTRIBUTES TO SURVIVAL OF POPULATIONS (RESOURCE PARTITIONING)
Untitled Slide
ORGANISMS EXCHANGE INFORMATION DUE TO INTERNAL CHANGES; EXTERNAL CUES
CHANGES BEHAVIORS, IE: PREDATOR WARNINGS
COMMUNICATION OCCURS THROUGH VARIOUS MECHANISMS
ANIMALS USE VISUAL, AUDIBLE, CHEM, TACTILE, ELEC SIGNALS
INDICATES DOMINANCE, FIND FOOD, TERRITORY & ENSURE REPRO SUCCESS
LIVING SYSTEMS HAVE MANY SIGNAL BEHAVIORS OR CUES
CHANGES BEHAVIOR OF OTHER ORGS; RESULTS IN DIFF REPRO SUCCESS
RESPONSES TO & COMMUNICATION OF INFO
VITAL TO NATURAL SELECTION AND EVOLUTION
NAT. SEL. FAVORS INNATE & LEARNED BEHAVIORS
THAT INCREASE SURVIVAL & REPRODUCTIVE FITNESS

COMMUNITIES ARE COMPOSED OF POPS OF ORGANISMS
THEY INTERACT IN COMPLEX WAYS
MATHEMATICAL/COMPUTER MODELS
ILLUSTRATE/INVESTIGATE POP INTERACTIONS
MATHEMATICAL MODELS & GRAPHS USED TO
ILLUSTRATE POPULATION GROWTH PATTERNS & INTERACTIONS
DENSITY DEPENDENT LIMITING FACTORS
DENSITY INDEPENDENT LIMITING FACTORS

INTERACTIONS AMONG LIVING SYSTEMS & W/THEIR ENVIRONMENT
RESULT IN THE MOVEMENT OF MATTER & ENERGY
CHANGES IN REGIONAL/GLOBAL CLIMATE & ATMOSPHERIC COMPOSITION
INFLUENCE PATTERNS OF PRIMARY PRODUCTIVITY
