(Typewriter comment - negative relationship because both sexes are competing
- involves stressful behaviour (stress of density)
- abundance and distribution of poppulations and communities
and how species interact with one another (excluding predator
and prey) relationship.)
Interspecific Competition
Outline
Interspecific competition
Competitive interactions
Outcomes of interspecific competition
Competitive exclusion
Resource partitioning
Ecological niches
Competition and natural selection
Species
Interactions
Species
occupying
the
same
physical
area
interact
with
one
another
All
individuals
seek
access
to
basic
resources
and
so
come
into
contact
with
individuals
of

(and
same)
species
Interspecific

Predator
prey
Host

Mutualism
(Typewriter comment - species compete for resources.
- limited resources = organisms have interaction with one another

Only pages 1-3 are available for preview. Some parts have been intentionally blurred.

- different species compete for resources, have a predator-prey relation-
ship, host parasite relationship or a mutualistic type relationship where they
have a negative negative interaction.)

Only pages 1-3 are available for preview. Some parts have been intentionally blurred.

(Typewriter comment - when two difference species compete, interspecific competi
tion takes
place reducing reproductive success (Fitness). this is a negative negative
type or relationship so both teh species lose, the loss might be very
large that they will hinder the fitness of both the species.
- decrease in rep affects distribution and abundance.
