Annotation -
This course provides a comprehensive introduction to insect ecology, emphasising insects as dominant and functionally crucial components of terrestrial and freshwater ecosystems. It explores the extraordinary diversity of insects, its global patterns, and the ecological and evolutionary processes shaping their distribution. A major focus is placed on insect interactions within communities, including herbivory, pollination, predation, parasitism, mutualisms, and migration, with attention to ecological trade-offs, specialisation, and trophic networks. The course further examines the importance of insects for ecosystem functioning and human well-being, including ecosystem services and disservices, and addresses the causes, consequences, and specific challenges of insect declines. By integrating ecological theory with conservation principles and regionally relevant examples, particularly from Czechia, the course equips MSc students with a solid conceptual framework for understanding, analysing, and conserving insect biodiversity in a rapidly changing world.

In 2026, the first lecture will be on Monday 16th February.

Syllabus -

Diversity of insect: how diverse insect is, causes of insect diversity, patterns and causes of unequal distribution of insect diversity - latitude, altitude, and other factors, biogeography, hotspots.

Insect in communities and ecosystems: Herbivory - advantages and disadvantages of herbivory for insects, plant defence against herbivores, specialisation of insect herbivores, impact of insect herbivory on ecosystems and communities. Pollination - origin and evolutionary importance of pollination by insects and other animals, rewards for plant visitors, insect-related pollination syndromes, specialisation/generalisation of pollination systems. Predation - insects as predators and prey, impact of insect predation on communities, specialisation of insect predators, interactions among predators and prey in complex trophic networks. Other roles of insects in communities - parasitoids, parasites, entomochory, relationships with ants, more complicated mutualism, trade-offs. Insect migrations.

Importance and conservation of insects: Importance of insects for humans, ecosystem service and other economic aspects, insects as pathogen vectors, reasons for insect conservation, status and causes of insect endangerement, insect specifics in conservation biology, causes of endangerement and principles of conservation of insects in Czechia.

Learning outcomes -

KNOWLEDGE

After completing the course, the student will be able to:

  • Explain the magnitude, patterns, and drivers of insect diversity across spatial gradients, including latitude, altitude, and biogeographical regions.
  • Understand the ecological roles of insects in communities and ecosystems, including herbivory, pollination, predation, and mutualisms.
  • Describe evolutionary and ecological mechanisms underlying insect–plant and insect–animal interactions, including specialisation, generalisation, and trade-offs.
  • Understand trophic interactions involving insects, including food webs, ecological networks, and top-down and bottom-up effects.
  • Explain the ecological and evolutionary basis of insect migration and its consequences for populations and communities.
  • Understand the principles of insect conservation biology, including causes of insect decline, ecosystem services, and taxon-specific conservation challenges.

SKILLS

After completing the course, the student will be able to:

  • Interpret patterns of insect diversity and distribution using ecological and biogeographical frameworks.
  • Critically evaluate empirical studies on insect ecology, species interactions, and conservation.
  • Integrate ecological theory with real-world examples of insect–plant, insect–predator, and mutualistic interactions.
  • Apply ecological reasoning to assess drivers of insect endangerment and the effectiveness of conservation measures.
  • Synthesize information across organisational levels, from individual behaviour to community and ecosystem processes.

COMPETENCES

After completing the course, the student will be able to:

  • Develop a mechanistic understanding of insect roles in ecosystem functioning and biodiversity maintenance.
  • Assess ecological consequences of changes in insect populations for communities, ecosystems, and human society.
  • Formulate evidence-based arguments for insect conservation grounded in ecological theory and empirical data.
  • Communicate complex ecological concepts related to insect ecology clearly and accurately to both specialist and non-specialist audiences.
  • Build a strong conceptual foundation for advanced research or applied work in insect ecology, conservation biology, and related fields.
