Herpetology Course

Lesson 1 • Overview of Reptile Diversity

Surveys the four living reptile orders and their evolutionary relationships. Students distinguish major lineages by morphology and ecology.

Lesson 2 • Overview of Amphibian Diversity

Introduces the three amphibian orders: Anura, Urodela, and Gymnophiona. Students recognize major groups and their distinguishing characteristics.

Lesson 3 • Defining Herpetology as a Discipline

Covers the history, scope, and subdisciplines of herpetology. Provides context for why reptiles and amphibians are studied together scientifically.

Lesson 4 • Scientific Nomenclature and Taxonomy

Teaches binomial nomenclature and taxonomic hierarchy as applied to herps. Accurate naming is essential for all subsequent identification and research work.

Lesson 1 • Digestive and Excretory Systems

Covers feeding strategies, digestive anatomy, and nitrogenous waste excretion. Students understand how diet and water availability shape physiology.

Lesson 2 • Integumentary Systems Compared

Contrasts amphibian moist, permeable skin with reptilian keratinized scales. Students connect skin structure to physiological functions like respiration and water balance.

Lesson 3 • Sensory Systems and Nervous Function

Describes visual, chemosensory, auditory, and thermoreceptive systems. Students link sensory adaptations to behavior and ecological niche.

Lesson 4 • Skeletal and Muscular Systems

Examines skeletal adaptations across major herp groups. Students relate bone structure to locomotion, feeding, and taxonomic classification.

Lesson 1 • Principles of Ectothermy

Defines ectothermy and contrasts it with endothermy. Students understand how environmental temperature drives metabolic rate and performance in herps.

Lesson 2 • Behavioral Thermoregulation Strategies

Covers basking, shuttling, and microhabitat selection as thermoregulatory behaviors. Students interpret field observations through a thermal ecology framework.

Lesson 3 • Dormancy: Brumation and Estivation

Distinguishes cold-induced brumation from heat- or drought-induced estivation. Students recognize physiological changes and ecological triggers for dormancy.

Lesson 1 • Temperature-Dependent Sex Determination

Explains how incubation temperature determines sex in many reptiles. Students assess conservation implications of climate-driven sex ratio skews.

Lesson 2 • Mating Systems and Sexual Selection

Covers courtship displays, mate choice, and competition in reptiles and amphibians. Students identify how sexual selection shapes morphology and behavior.

Lesson 3 • Oviparity, Viviparity, and Ovoviviparity

Compares egg-laying, live-bearing, and intermediate reproductive modes. Students evaluate ecological drivers of each strategy across taxa.

Lesson 4 • Amphibian Metamorphosis and Development

Traces larval development through metamorphosis to terrestrial life. Students understand hormonal control and ecological significance of biphasic life cycles.

Lesson 1 • Community Ecology and Interspecific Interactions

Analyzes competition, mutualism, and parasitism involving herps. Students assess how herps structure ecological communities.

Lesson 2 • Home Range, Territory, and Movement

Covers spatial ecology including home range estimation and territorial behavior. Students apply movement data to habitat connectivity and conservation planning.

Lesson 3 • Microhabitat and Macrohabitat Selection

Distinguishes fine-scale microhabitat from broad macrohabitat preferences. Students predict species occurrence based on habitat structure and resources.

Lesson 4 • Predator-Prey Dynamics

Examines herps as both predators and prey within food webs. Students evaluate antipredator adaptations and their ecological consequences.

Lesson 1 • Morphological Identification Techniques

Teaches use of scalation, body proportions, and color patterns for species ID. Students apply dichotomous keys and photographic references in field settings.

Lesson 2 • Mark-Recapture and Population Estimation

Introduces mark-recapture designs and population size estimators. Students calculate abundance and assess assumptions underlying each method.

Lesson 3 • Acoustic and Visual Survey Methods

Covers call-based amphibian surveys and visual encounter surveys for reptiles. Students select appropriate methods based on target species and habitat.

Lesson 4 • Data Recording and Voucher Specimens

Establishes standards for field data sheets, GPS recording, and specimen preservation. Students produce records that meet scientific and regulatory requirements.

Lesson 1 • Envenomation First Aid and Medical Response

Provides evidence-based first-aid protocols for snakebite and toxic exposure. Students recognize symptoms and understand antivenom use and limitations.

Lesson 2 • Non-Venomous Defense Adaptations

Surveys mechanical, behavioral, and chemical defenses in non-venomous species. Students evaluate how these strategies reduce predation risk.

Lesson 3 • Venom Delivery Systems

Compares fang types: solenoglyphous, proteroglyphous, and opisthoglyphous. Students identify delivery system from fang morphology and relate it to envenomation risk.

Lesson 4 • Snake Venom Composition and Function

Analyzes proteolytic, neurotoxic, and hemotoxic venom components. Students connect venom chemistry to prey immobilization and predator deterrence.

Lesson 1 • Conservation Policy and Stakeholder Engagement

Links scientific findings to regulatory frameworks and community outreach. Students develop communication strategies for diverse conservation audiences.

Lesson 2 • Threats to Reptile Populations

Identifies overexploitation, invasive species, and road mortality as key reptile threats. Students prioritize threats by severity and tractability for management.

Lesson 3 • Protected Areas and Habitat Management

Evaluates protected area design and habitat restoration for herp conservation. Students apply landscape ecology principles to reserve planning.

Lesson 4 • Captive Breeding and Reintroduction

Covers ex situ breeding programs and criteria for successful reintroduction. Students assess genetic management and post-release monitoring protocols.
