Which of the following is NOT one of the main sensory modalities used in animal communication?
Auditory signals
Electromagnetic signals
Chemical signals
Visual signals
While visual, auditory, chemical, and tactile signals are primary modalities, electromagnetic communication (beyond simple bioluminescence) is not a general mode of inter-animal signaling. Most animals rely on the other four channels for sending and receiving messages. Bioluminescence is considered a subset of visual signaling. https://www.sciencedirect.com/topics/neuroscience/animal-communication
What is the primary receptor type for detecting airborne chemical signals in mammals?
Mechanoreceptors
Thermoreceptors
Photoreceptors
Olfactory receptors
Mammals detect airborne chemicals primarily through olfactory receptors located in the nasal epithelium. These G-protein - coupled receptors bind odorant molecules and trigger neural signals to the olfactory bulb. Photoreceptors detect light, not odors. https://www.ncbi.nlm.nih.gov/books/NBK53924/
In a typical songbird, which sensory structure is most critical for vocal learning?
Statocyst
Basilar papilla
Jacobson's organ
Lateral line
Songbirds use the basilar papilla (their auditory organ, analogous to the mammalian cochlea) to perceive and practice song. Accurate auditory feedback through this structure is crucial for imitating adult tutors. The lateral line is found in fish, and Jacobson's organ detects pheromones. https://www.frontiersin.org/articles/10.3389/fnins.2016.00226/full
Which animal uses pheromones to mark territory and regulate social hierarchy?
Dolphins
Wolves
Honeybees

Wolves and many other mammals secrete pheromones in urine or glandular secretions to mark territory and convey social status. Honeybees communicate pheromonally but not typically for territory marking. Cuttlefish use visual displays, and dolphins rely mostly on acoustic signals. https://www.sciencedaily.com/releases/2007/12/071218154420.htm
What type of receptor do fish use to detect water-borne vibrations?
Olfactory lamellae
Lateral line neuromasts
Statocysts
Ampullae of Lorenzini
The lateral line system in fish consists of neuromasts that detect pressure changes and water vibrations. Ampullae of Lorenzini detect electrical fields (in sharks), while statocysts sense balance, and olfactory lamellae detect odors. https://www.britannica.com/science/lateral-line
Which phenomenon describes an animal ignoring a constant, irrelevant stimulus?
Dishabituation
Habituation
Sensitization
Conditioning
Habituation is the decreased response to a repeated, irrelevant stimulus. It allows animals to focus on novel or biologically important signals. Sensitization is the opposite effect - heightened response. https://www.sciencedirect.com/topics/neuroscience/habituation
Which sensory cue is most used by nocturnal moths to find mates?
Courtship song
Bioluminescence
Pheromones
Ultraviolet patterns
Nocturnal moths commonly use highly sensitive pheromone detection to locate mates over long distances.

What term describes changes in signal structure to match environmental transmission properties?
Dishabituation
Signal adaptation
Sensory bias
Habituation
Signal adaptation refers to evolutionary or behavioral modifications in a signal's features - like frequency or amplitude - to optimize transmission under specific environmental conditions.

Multimodal signaling
Multimodal signaling refers to communication that combines two or more sensory channels - like visual and auditory - to improve efficacy or reliability of the message. This enhances detection under varied conditions. https://www.annualreviews.org/doi/10.1146/annurev-ecolsys-110411-160516
Which acoustic parameter is most often altered in bird calls to avoid degradation in dense forest?
Higher frequencies
Increased amplitude modulation
Lower frequencies
Broadband noise
Dense vegetation attenuates high frequencies more, so forest-dwelling birds often use lower-frequency calls that travel farther and degrade less. Open-habitat species may use higher frequencies. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2941658/
What is the critical period in bird song learning?
Developmental window when juveniles memorize tutor song
Season of heightened reproductive activity
Phase when birds practice flight
Time when adult birds teach directly by singing
The critical period is a developmental phase when juvenile songbirds must hear adult tutor songs to develop normal species-specific song; missing it leads to abnormal vocalizations. It is a classic example of experience-dependent learning. https://www.annualreviews.org/doi/10.1146/annurev.ps.31.020182.001331
Which mechanism underlies honest signaling according to the handicap principle?

Cheat Sheet

  1. Sensory Modalities in Animal Communication -

    Animal communication involves what type of sensory input across five main channels: visual, auditory, chemical, tactile, and electrical (often remembered by the mnemonic VACTO). For instance, honeybees perform the waggle dance (visual/tactile) to convey food location, and electric fish generate pulses to signal territory. Reviewing VACTO helps you ace animal communication quiz questions in chapter 51 animal behavior.

  2. Proximate Causation (Mechanism & Development) -

    Proximate explanations address "how" behaviors occur by examining physiological mechanisms and ontogeny; Tinbergen's questions 1 and 2 focus on these aspects. A classic example is song learning in zebra finches, where hormone regulation and social learning shape vocal development. Understanding this distinction is key for animal behavior trivia and chapter 51 assessments.

  3. Ultimate Causation (Function & Evolution) -

    Ultimate causation explores "why" behaviors evolved by analyzing fitness benefits and phylogenetic history (Tinbergen's questions 3 and 4). Alarm calls in ground squirrels, for instance, reduce predation risk for kin, illustrating adaptive value. Recognizing function vs. mechanism solidifies concepts for the animal behavior quiz and communication quiz alike.

  4. Chemical Signals and Pheromones -

    Pheromones are chemical messengers critical in insect mating, territory marking, and social organization; male silk moths detect female pheromones at parts-per-trillion sensitivity. Applications in pest control leverage this by deploying synthetic pheromone traps to disrupt mating. Grasping chemical signaling enriches your in-depth knowledge of chapter 51 animal behavior topics.

  5. Honest Signaling and the Handicap Principle -

    The Handicap Principle posits that reliable signals are costly to produce, ensuring honesty; peacock tails are energetically expensive but indicate male fitness. This concept links ecology, evolution, and communication theory, illustrating why extravagant traits persist. Remember this principle to nail questions on signal reliability in animal communication trivia.
