What is resource partitioning in niches?
Resource partitioning refers to competing species specializing so that their niches differ in at least one major factor.
What distinguishes fundamental niche from realized niche?
What distinguishes fundamental niche from realized niche?
The fundamental niche describes the potential living factors, while the realized niche is the actual conditions under which a species lives.

Study Notes
Species Interactions Overview
- Interspecific interactions can yield both positive and negative outcomes, impacting community dynamics.
- Types of negative interactions: competition, predation, herbivory, parasitism, and amensalism.
- Positive interactions fall under facilitation, which includes commensalism (one benefits, one is unaffected) and mutualism (both benefit).
Mutualism Types
- Obligate mutualism: Both species are interdependent for survival.
- Facultative mutualism: Species can survive independently but gain advantages from their relationship.
Niches and Resource Use
- Resource partitioning often occurs to reduce competition, leading to specialized niches among competing species.
- The fundamental niche includes all possible environments a species can inhabit, while the realized niche is the actual conditions where the species exists, shaped by interspecific interactions.
Community Dynamics
- Interspecific interactions are fluid and significantly influence community structure and species fitness, leading to evolutionary changes over time.
Specific Interaction Types
- Amensalism: One species is harmed while the other remains unaffected.
- Predation: One species benefits by consuming another.
- Neutralism: No benefit or harm occurs to interacting species.
Mimicry and Coloration
- Aposematic coloration: Bright colors warn predators of toxicity.
- Batesian mimicry: Non-toxic species mimic the warning colors of toxic ones.
- Mullerian mimicry: Two toxic species share similar warning patterns.
Community Composition and Structures
- A community is defined as all populations of different species in a shared area.
- Competitive exclusion occurs when intense competition leads to one species outcompeting and eliminating another.
Ecological Roles
- An ecological niche encompasses the functional role of an organism and its environmental interactions, including what resources it uses or tolerates.
Symbiosis Types
- Symbiosis can range from mutualistic, parasitic, to commensalistic interactions.
- Facilitation involves interactions that do not harm any species while benefiting at least one.
Other Notable Terms
- Herbivory: A specific type of predation where animals eat plants.
- Interspecific competition: Competition between individuals of different species for similar resources.
- Cryptic coloration: Camouflage that allows species to blend into their surroundings.
- Character displacement: Morphological changes that evolve in two sympatric species to reduce competition.
Summary of Terms
- Interspecific interaction: Engagement between individuals of different species.
- Resource partitioning: Differentiation in resource use to minimize competition.
