CONSERVATION BIOLOGY

Course objectives

Educational goals Knowing the basic principles of Conservation Biology, with a particular reference to animal populations. Definition of biodiversity, from the intra-specific level to ecosystems; definition of the values of biodiversity and of the main threats to its conservation. Knowing the concepts of extinction and species/populations vulnerability. Definition of the main issues for the conservation of animal biodiversity and of the role of protected areas. Definition of the basic principle of sustainable development. The prerequisites include basics of genetics, taxonomy and ecology, which should already be acquired through the first and second year of study. The contents of the course are particularly linked to those of Zoology and Ecology. Specific objectives A) Knowledge - basic principles of Conservation Biology with its philosophical grounds. - concept of biodiversity and of its values - main threats to biodiversity - concept of extinction and of species vulnerability - main applications of conservation biology from the species distribution models to the population viability analysis - role and importance of protected areas in conservation biology - basic principles of sustainable development. B) Application of knowledge and understanding - correct use of scientific language - theoretical framing of selected case studies - identification of the ecological, sociological, and economical parameters which define selected problems in conservation biology - identification of the methodological approaches which better suits the common applications in conservation biology C) Judgement - acquiring the capacity of critical examination of a problem through the knowledge of the field of study - being able to put the theoretical knowledge in practical case studies - evaluating the need to elaborate on the knowledge D) Communication abilities - being able to communicate accurately and adequately what is being learned E) Learning abilities - to make proper use of the scientific language which characterize the field of Conservation Biology, showing also the capacity to use the most appropriate communication techniques - to put in the correct relationship all knowledge acquired during the course of study - to identify the most important points in the topics covered

Course program
Origin, function and principles of conservation biology. Biodiversity across hierarchical levels and scales (genetic, functional, ecosystemic, alpha, beta, gamma). Quantification of biodiversity (global estimates and biodiversity indicators), global biodiversity patterns. Biodiversity values (economic, direct and indirect, intrinsic and cultural). Basics of animal ecology, population biology and spatial ecology: population structure, abundance, density, exponential and logistic growth models, carrying capacity, demographic fluctuations, competition and predation, geographic range, dispersion, dispersal, spatially structured populations and metapopulations, migrations, home range, territory, habitat. Global biodiversity trends and threats: habitat destruction, fragmentation and degradation, pollution, climate change, overexploitation, invasive species, diseases, trophic cascades. Species and local extinctions, mass extinctions, current extinction rates, extinction debts, species-area curves, island biogeography, intrinsic vulnerability to extinction, Rabinowitz’s rarity forms. Issues with small populations, minimum viable population, minimum dynamic area, loss of genetic diversity, inbreeding and outbreeding depression, effective population size. Genetic, demographic and environmental stochasticity, environmental catastrophes, Allee effect, extinction vortex. Population-level approaches, population estimates, population viability analysis, monitoring, connectivity, population restoration, reintroductions, introductions. Species-level approaches, Red List, Edge initiative, distribution modelling. Ecosystem-level approaches, biodiversity assessments. Restoration ecology, Rewilding, dynamic equilibria. Biodiversity protection and international agreements. Ex-situ conservation approaches: zoo and aquariums. Protected areas, goals, limitations, categories, assessments, SLOSS debate, ecological networks. Conservation prioritization: species-level and spatial-scale. Systematic conservation planning. Conservation outside protected areas. Proactive and reactive conservation. Sustainable development.
Prerequisites
Although no exam is officially required to undertake this course, the course is strongly based on notions, terminology and mechanisms acquired in the course of ecology, and secondarily genetics and zoology. Hence, it is strongly recommended to take the course and examination only after taking these other examinations.

Frequency
The attendance of the classes is not mandatory but is strongly encouraged.
Exam mode
The final exam consists of a written exam with 15 multiple choice and 3 open-ended questions, and a short oral exam. The final mark will be based on the written and oral exam. There are no mid-term tests during the course.
Lesson mode
The course is structured in frontal theoretical lessons. Lessons are held weekly in class through the use of Power Point presentations.
