Amphibian Biology Course

Lesson 1 • Major Amphibian Groups Overview

Introduces the three living orders: Anura, Urodela, and Gymnophiona. Provides the taxonomic framework used throughout the course.

Lesson 2 • Amphibian Diversity and Species Richness

Surveys global species counts and hotspots of amphibian diversity. Frames the scale of biodiversity relevant to conservation and research careers.

Lesson 3 • External Anatomy and Morphology

Covers body plans, skin structure, and limb morphology across amphibian groups. Enables accurate field identification and specimen description.

Lesson 4 • Internal Organ Systems

Examines respiratory, circulatory, and digestive systems unique to amphibians. Connects internal anatomy to physiological functions covered in later chapters.

Lesson 1 • Dormancy, Estivation, and Hibernation

Analyses metabolic depression strategies used during extreme seasonal conditions. Prepares learners to interpret activity patterns in field and captive settings.

Lesson 2 • Feeding, Digestion, and Nutrition

Examines prey capture methods, digestive efficiency, and nutritional requirements. Provides practical knowledge for captive husbandry and field diet studies.

Lesson 3 • Respiration and Gas Exchange

Details the multiple respiratory surfaces amphibians use simultaneously. Connects respiratory physiology to habitat use and activity levels.

Lesson 4 • Thermoregulation in Ectotherms

Explains behavioural and physiological strategies amphibians use to manage body temperature. Builds on anatomy knowledge to link structure with thermal function.

Lesson 1 • Reproductive Strategies and Mating Systems

Surveys oviparity, viviparity, and direct development across amphibian taxa. Establishes the diversity of reproductive modes before examining specific mechanisms.

Lesson 2 • Metamorphosis and Post-Metamorphic Growth

Details hormonal control of metamorphosis and juvenile growth trajectories. Prepares learners to monitor developmental milestones in research and husbandry.

Lesson 3 • Fertilisation and Egg Development

Covers internal versus external fertilisation and embryonic development stages. Provides the cellular foundation for understanding larval biology.

Lesson 4 • Courtship Behaviour and Communication

Examines acoustic, visual, and chemical signals used during mate selection. Links behavioural ecology to reproductive success and population dynamics.

Lesson 1 • Navigation, Orientation, and Homing

Examines celestial, magnetic, and olfactory cues used for navigation. Supports understanding of migration patterns introduced in the ecology chapter.

Lesson 2 • Acoustic Communication and Bioacoustics

Analyses call types, production mechanisms, and acoustic environment effects. Provides skills for passive acoustic monitoring used in field surveys.

Lesson 3 • Social Behaviour and Aggregation

Describes territorial defence, aggregation benefits, and kin recognition. Rounds out behavioural ecology before moving to applied field techniques.

Lesson 4 • Sensory Systems and Perception

Covers vision, hearing, chemoreception, and the lateral line system. Links sensory anatomy to behavioural responses studied in subsequent sections.

Lesson 1 • Feeding Ecology and Trophic Roles

Positions amphibians within food webs as both predators and prey. Connects trophic ecology to ecosystem function and pest regulation services.

Lesson 2 • Community Interactions and Coexistence

Analyses competition, predation, and mutualism shaping amphibian communities. Prepares learners to evaluate multi-species management scenarios.

Lesson 3 • Home Range and Movement Patterns

Examines daily and seasonal movement, migration routes, and site fidelity. Provides data interpretation skills for telemetry and mark-recapture studies.

Lesson 4 • Habitat Types and Microhabitat Selection

Identifies the range of terrestrial, aquatic, and arboreal habitats amphibians occupy. Builds spatial awareness needed for field survey design.

Lesson 1 • Biosecurity and Disease Prevention

Details decontamination protocols, quarantine procedures, and equipment hygiene. Prepares learners to prevent pathogen spread during fieldwork and captive care.

Lesson 2 • Environmental Contaminants and Toxicology

Examines pesticide, heavy metal, and endocrine disruptor effects on amphibian physiology. Links contaminant exposure to deformities and reproductive failure.

Lesson 3 • Common Infectious Diseases

Covers chytridiomycosis, ranavirus, and bacterial infections causing population declines. Establishes disease recognition skills critical for conservation work.

Lesson 4 • Health Assessment and Diagnostic Techniques

Introduces physical examination, swabbing, and necropsy procedures for amphibians. Provides practical diagnostic skills applicable in field and laboratory settings.

Lesson 1 • Visual Encounter and Transect Surveys

Teaches standardised visual encounter surveys and line transect protocols. Builds core detection skills used across most amphibian monitoring programmes.

Lesson 2 • Data Management and Survey Reporting

Covers field data entry, database management, and report writing standards. Prepares learners to produce professional outputs required by monitoring programmes.

Lesson 3 • Capture, Marking, and Handling Protocols

Details safe capture methods, marking techniques, and ethical handling standards. Ensures animal welfare compliance and data quality in mark-recapture studies.

Lesson 4 • Aquatic Sampling Techniques

Introduces dip-netting, funnel trapping, and egg mass counting for aquatic stages. Connects larval ecology knowledge to practical wetland survey methods.

Lesson 1 • Protected Area Management for Amphibians

Examines reserve design, buffer zones, and connectivity corridors for amphibian conservation. Applies population ecology concepts to spatial planning decisions.

Lesson 2 • Ex Situ Conservation and Captive Breeding

Covers assurance colony management, genetic diversity maintenance, and reintroduction planning. Integrates health and reproductive biology into captive programme design.

Lesson 3 • Regulatory Frameworks and International Agreements

Reviews wildlife trade controls, protected species listings, and international conservation agreements. Prepares learners to navigate compliance requirements in professional practice.

Lesson 4 • Conservation Planning and Prioritisation

Applies structured decision-making and threat assessment tools to set conservation priorities. Culminates the course by integrating all prior knowledge into strategic planning.
