- Representing others' work as your own
- Using AI generators to create text
- If unsure about plagiarism, ask for clarification.
What is Animal Physiology?
- The study of how animals work
- Two types of questions:
- Proximate cause (mechanism): Explains how an organism works, focusing on functional processes
- Ultimate cause (origin): Explains why an organism is built a certain way, considering evolutionary change and adaptive significance.
- Physiology is an integrative field of study.
Unifying Themes of Animal Physiology
- Physiological processes obey the laws of physics and chemistry.
- Physiological processes are typically regulated.
- Physiological phenotype is a product of both genotype and environment.
- Genotype is a product of evolution.
Physical Laws and Chemistry
- Mechanical engineering rules apply to the physical properties of animals (e.g., collagen in the aorta).
- Chemical laws govern molecular interactions (e.g., effects of temperature).
- Body size influences biochemical and physical patterns.
Regulation of Physiological Processes
- Animals must deal with constantly changing external and internal (endogenous) environments.
- Organisms must maintain a suitable internal environment (homeostasis).
Control of Homeostasis
- Feedback loops (mainly negative) or reflex control pathways, using antagonistic controls.
- Antagonistic controls act in opposing ways to regulate a system
Strategies for Coping with Changing Conditions
- Conformers: Allow internal conditions to fluctuate with external changes
- Regulators: Maintain relatively constant internal conditions regardless of external conditions
Temperature and Physiological Strategy
- Temperature and physiological strategies help define an animal's range limits.
Phenotype and Environment
- Genotype: Genetic makeup of an organism.
- Phenotype: Physical characteristics, physiology, and behavior.
- Phenotypic plasticity (non-reversible): A single genotype produces different phenotypes depending on the environment.
-
Phenotypic flexibility (reversible):
- Within-generation plasticity (acclimation): Reversible changes within an organism's lifetime due to environmental conditions.
Evolution and Genotype
- The genotype is the result of evolutionary processes.
- Natural selection favors traits that improve fitness in a particular environment.
- Adaptions are evolutionary changes that enhance survival and reproduction.
