Learning outcomes of the course unit:

Zoology is one of the basic biological disciplines. Invertebrate Zoology deals with the study of anatomy, morphology, and systematics of invertebrates, their individual and historical development, zoological their distribution, studying the relationship of animals with other organisms and the dependence of animals on the environmental conditions of living.

Although some of its sections concerning the construction, vital functions, behavior and relationships of organisms with their environment, objects are not individual animals and animal kingdom as a whole.

Zoology of Invertebrates are interested in practical significance because among them there are many species directly or indirectly used by man, as well as crop pests, agents and vectors of various diseases. Data obtained as a result of zoological studies are widely used in agriculture, forestry, animal husbandry, fisheries, ecology and environmental protection.

The acquisition of a set of theoretical and practical zoological knowledge are indispensable for a full presentation of the students in the years of training and their future fieldwork specialists-ecologists.

Useful and harmful species studied in the special zoological disciplines, but they are a small part of the vast animal kingdom. The ever-increasing human intervention in nature leads to an increase in the number of endangered species.

Zoology is a system of concepts that are taught before teaching special disciplines. It appears as general biological introduction of applied biological sciences. Without knowledge of biology, classification and geographic distribution of animals is impossible to study and determine their relevance.

Planned learning activities and teaching methods:

Monological explanation (lecture, presentation,briefing, tutorials), Dialogue methods(conversation,discussion)

Lectures and seminars are conducted according to generally accepted requirements, maximum use of available technics ( microscopes and multimedia) and independent work by zoological material.

Assessment methods and criteria:

Exercises evaluation and written exam. The exercises are certified in the case of records of all issues.

The current assessment is based on current control after each exercise, practical exam and summarizing test on the lecture material. The rating is a six-point scale and a collection of the practical and theoretical exams.
