Study Notes

Organisms and Environment

Organisms respond to their environment with behaviors and physiological processes
Stimulus: an external signal causing a response
Tropism: growth toward (positive) or away from (negative) a stimulus (plants)
- Positive phototropism: growth towards light
- Gravitropism: growth downwards, roots
Taxis: directional movement toward or away from something (animals)
Kinesis: random movement related to a stimulus (animals)
Organisms communicate to benefit survival and reproduction through visual, tactile, audible, electrical, or chemical signals
- Aposematic coloration: warning coloration (poisonous organisms)
- Scent marking for territory or mate attraction
Animals often cooperate ensuring group survival
- Individuals may take on specific roles in the group
- Innate behavior: genetically determined, without prior knowledge
- Learned behavior: acquired through experience

Learned Behavior

Behavior: action carried out by muscles under nervous system control
Essential for animal survival and reproduction
Subject to natural selection
Simple and complex behaviors stimulated by sensory inputs
Niko Tinbergen's questions for understanding behavior
- What stimulus elicits the behavior?
- How does the animal's experience influence behavior?
- How does behavior aid survival and reproduction?
- What is the behavior's evolutionary history?
Types of Causation
- Proximate: how behavior occurs
- Ultimate: why a behavior occurs
Fixed Action Pattern (FAP): unlearned, automatic behavioral sequence (e.g., stickleback)
Sign Stimulus: external cue triggering a behavior
Migration: regular, long-distance movement
Behavioral Rhythms
- Circadian Rhythm: daily cycle (sleep-wake)
- Circannual Rhythm: annual cycle (migration)

Learning and Cognition

Imprinting: long-lasting behavioral response to a particular individual or object, usually in young animals
Spatial Learning: creating a memory of the spatial environment
Cognitive Map: mental representation of the surroundings
Associative Learning: associating one environmental feature with another (classical and operant conditioning)
Cognition: awareness, reasoning, recollection, and judgment (involves problem-solving)
Social Learning: learning from observing others

Population Ecology

Population: group of individuals of the same species inhabiting the same area, interacting and breeding
Exponential Growth: population increasing at a constant rate in unlimited resources
Logistic Growth: population growth rate slows as it approaches carrying capacity
Carrying Capacity (K): maximum population size an environment can sustain
Population Density: number of individuals per unit area
Density-dependent factors: birth/death rates vary with density (e.g., food, predators, disease)
Density-independent factors: birth/death rates remain the same (e.g., natural disasters)

Community Ecology

Community: group of populations of different species interacting closely enough to affect each other
Interspecific Interactions: +/- interactions between species
- Exploitation: +/- e.g., predation, herbivory, parasitism
- Competition: -/- e.g., for resources
- Symbiosis: close relationship (+/- or 0) e.g., mutualism, commensalism
Niche: sum of species' use of biotic and abiotic resources.
Niche partitioning: similar species coexisting by using resources differently
Character Displacement: traits diverge more in sympatric than allopatric populations
Community stability: tendency to reach and maintain a relatively stable composition
Resilience: the ability to recover from disturbance

Ecosystem Ecology

Ecosystem: living and nonliving components of an area
Trophic Levels: feeding relationships in an ecosystem
- Producers, Primary consumers, Secondary consumers, Tertiary consumers
Energy flow: transfer of energy through trophic levels
Biomass: total mass of organisms in an area
Energy pyramid: loss of energy as it moves through trophic levels
Biogeochemical Cycles: movement of nutrients through ecosystems
Ecosystems and Biodiversity: factors affecting community diversity

Biodiversity

Species Richness: Number of different species
Relative Abundance: proportion of each species in a community
Species Diversity: combines richness and evenness (relative abundance of species)
Ecological Disturbances: events that remove or alter resources
Intermediate Disturbance Hypothesis: intermediate levels of disturbance tend to support higher numbers of species
Succession: changes in species composition of a community over time (ex: primary and secondary succession)
Biogeographic Factors: influence ecosystem diversity
- Latitudinal Gradient: diversity increases towards equators
Species-area curve: the larger the geographic area, the greater the species diversity
Ecosystem Services: important benefits provided by ecosystems to humans
- Water purification, pollination, nutrient cycling (ex.)

Human Impact

Biological Magnification: toxins accumulating more at higher trophic levels
Invasive Species: species introduced to new ecosystems negatively impacting native biodiversity.
