Overview

Our programme features practical skills for biodiversity fieldwork with for major taxa such as plants, birds, mammals, amphibians and reptiles and for butterflies and other insects. But participants also learn how to use modern statistical techniques to analyze biodiversity using R and its packages for biodiversity data analysis (e.g. VEGAN). The programme uses lectures, fieldwork, computer labs and a group project to give participants an understanding of the principles of modern biodiversity theory and practice all the way from ecological fieldwork, through data analysis, to conservation policy. This happens in the heart of one of the most exciting natural areas of Europe – the Vikos-Aoos National Park of the Pindos Mountains.

The cultural landscapes of Zagori

Kalliopi Stara (University of Ioannina, Greece)

This session will introduce students to the natural history of Zagori and will help them to “read” the landscapes of the area. It gives basic information about the conservation importance of the North Pindos National Park and the bio cultural value of the area and its landscapes from the  mountain picks of Tymfi and Smolikas to the warm valleys of Vikos and Aoos. Land-use practices that create “working landscapes”, culture imprints in to the landscape such as social orders, conventions and borders between domesticated land and wilderness and local cosmologies are the main elements that we will use to interpret the mountain landscapes of the area beyond their recent advertisement as places of a “virgin nature” and “unspoiled tradition”.

 

Sampling methods for biodiversity assessment and monitoring

Alessandro Chiarucci (University of Bologna, Italy)

Assessing and monitoring species diversity over large scales, such as natural parks or administrative regions, is a really difficult task especially for species-rich taxa. As a consequence this is one of the major tasks of present day conservation biology but it is also a major challenge in ecology. Species richness estimators and rarafaction techniques are now widely used, especially because they are easy available in many softwares. However, the use of these techniques is not free of problems and needs to be applied under ceratin limitations. This lecture will present some possible solutions in assessing and monitoring large scale species diversity, especially discussing sampling design issues and how they can affect the resulting species richness estimates.

 

Spatial scales in biodiversity

Alessandro Chiarucci (University of Bologna, Italy)

Species diversity is deeply affected by spatial scale. Species-area curves are the most important models to relate species diversity to the spatial scales. The most applied models of species-area curves, namely the Arrhenius’ power function and Gleason’s exponential model, will be introduced and discussed in this lecture. However, spatial scale does not act as a single component if affecting species richness, just because it can represent different natural phenomena. The effects of the different components of the spatial scales, namely grain, extent and focus, on the species richness will be discussed in this lecture together with a final look to the most recent advancements on modelling species-area curves.

 

Ecosystem services and biodiversity

Gabor Lovei (Aarhus University, Denmark)

Ecosystem services were recognised relatively recently, and were brought to the forefront with the Millennium Ecosystem Assessment (1999-2004). Biodiversity is intuitively linked to ecosystem services, but the precise mechanism is not known. This area has triggered one of the “boom” research fields in recent ecology. In this module, I present the ecosystem services concept and taxonomy, survey the history of the biodiversity-ecological functioning debate, starting with the various theories suggested (statistical artefact, overhead theory, production theory) and the current lines of empricial evidence. Above-belowground linkages and functional vs. species diversity approaches will be detailed and discussed. I shall also touch on the hoped-for advantages and pitfalls of the utilitarian approach to ecological functioning.

 

Network Analysis

Athanasios Kallimanis (University of Patras, Greece)

Alot of research in biodiversity has been focused towards analyzing the species composition of communities. However, of critical importance is not only what species constitute a community but also how do they interact. And even though pairwise interactions have always had a key role in ecology, the increase in the amount and availability of biological data highlighted the existence and importance of complex ecological networks (such as plant-pollinator interaction networks). The availability of powerful computational tools has facilitated wide access to such data, and a rapid increase in the relevant research publications, not only by ecologists but also by social scientists, physicists and mathematicians. In this module we will examine the methods available and also apply them to some ecological examples.

 

Analyzing Functional Diversity

Athanasios Kallimanis (University of Patras, Greece)

Biodiversity is a notoriously multifaceted ecological phenomenon. Most of the current research focuses on several aspects of taxonomic diversity. Functional diversity is the facet of biodiversity that reflects the range of things that organisms do in communities and ecosystems which is an important concept in ecology because it captures information on functional traits absent in classical indices of biodiversity. We will combine information from biodiversity datasets with the functional traits of species in order to estimate an array of functional diversity indices. We will explore the properties and associations between the different aspects of biodiversity.

 

Conservation Biology in practice

Vassiliki Kati (University of Patras, Greece)

In this introductory lecture, the science of conservation biology will be introduced. The main principles and characteristics of conservation biology will be presented. Students will learn about the main tools we dispose in order to face biodiversity loss. Concepts such as the hotspots of biodiversity, the techniques of reserve design, methods of rapid biodiversity assessment, gap analysis, species action plans, and concepts such as umbrella, flagship, or indicator species will be presented and enriched with examples from the real conservation world.

 

Biodiversity Theory

John M. Halley (University of Ioannina, Greece)

Measures of diversity. Models of community structure. We review different models of biodiversity of the ecological community. From populations to communities: what is a community? Different models of the community. Ecological foodwebs and assembly rules. The Preston, McArthur and other descriptions of community structure. Hubbell’s neutral model of biodiversity. The dynamics of the community – from cycles to evolution. Diversity and scale. Biogeography and species richness. The Arrhenius scaling relationship for biodiversity and area. Theories of the species-area relationship. Extinction and the SAR. Extinction debt.

 

Phylogenetic Diversity

Martin Wiemers (Helmholtz Centre for Environmental Research – UFZ, Halle, Germany)

Our knowledge about the phylogenetic relationships of organisms has been greatly enhanced in recent decades, especially due to molecular methods. At the same time, phylogenetic diversity is increasingly seen as an important aspect of species diversity, and methods have been developed to measure this component of natural diversity. The results can be important to inform the debate on prioritizing conservation actions. This lecture gives an introduction to the topic and presents different metrics of phylogenetic diversity which have been developed during the past 15 years.

Rarefaction technique

Alessandro Chiarucci (University of Bologna, Italy)

This session will familiarize students with the application of the rarefaction thechnique to the field data they have collected, in order to show how the changes of the expected sample size can affect the observed species richness values.

 

Databases for biodiversity. Design and implementation in MsAccess

Stefanos Sgardelis (Aristotle University of Thessaloniki, Greece)

This lab is in two parts. In the first part we design a database to keep records of plant species occurrence and abundance in several localities and habitat types. Our aim is to produce the schema of a relational database based on entity-relationship diagrams. We look at the structure of the bioGreece DB for reference. In the second part we implement a working prototype of our database in Microsoft Access.

 

Using molecular data for biodiversity studies

Martin Wiemers (Helmholtz Centre for Environmental Research – UFZ, Halle, Germany)

Creating phylogenetic trees is becoming increasingly easy, partly due to the development of streamlined procedures, and is no longer the realm of phylogeneticists only. This lab session will enable the ecologist to download and process molecular data from public databases in order to analyze phylogenetic relationships and calculate selected phylogenetic diversity indices.

The basis of all diversity assessment is field sampling. All methods have their advantages and disadvantages, but most importantly the limitations need careful scrutiny because this determines the reliability of the data obtained. Once the base data are of inferior quality, no amount of data analysis sophistication will render them reliable, and the conclusions will be false. Therefore field sampling is of critical importance.

 

 

 

 

 

Sampling Biodiversity of Birds and Reptiles (12h)

Vassiliki Kati, University of Patras, Department of Environmental and Natural Resources management, Greece

This session will introduce students to a range of different field sampling techniques and associated data treatment.
(a) Sampling passerine birds. The first part of the session focuses on small terrestrial bird sampling. Various bird census methods will be presented, as well as the ecology of passerine birds, their value as monitoring tool and the different types of bird songs. Students will have to conduct acoustic and visual sampling at early morning hours, filling a standard worksheet and recording the species richness of bird community in different sampling points in an agricultural ecosystem.
(b) Reptile sampling. The second part of the field session will introduce different survey methods for reptile diversity. It will focus on lizard and tortoise sampling, involving standard transects in an agricultural ecosystem.
(c) Data treatment. This session will introduce the methodology of setting up databases of biodiversity data. Data from bird and reptile sessions will be merged in a common database. Simple alpha and beta diversity analysis will follow, using either the real data from the morning field sessions, or data provided by the instructor. We will also introduce elements of community analysis, using CANOCO software.

 

Sampling Biodiversity of Invertebrates (12h)

Gabor Lovei (University of Aarhus, Denmark)

This session will introduce students to a range of different field sampling techniques and associated data treatment. In this session the participants will do small exercises using the basic field census techniques for birds and invertebrates. For invertebrates, visual censuses will be performed on available flowering plants, which will be used for biodiversity analyses, including species richness estimation, life form/functional diversity analysis, and diversity ordering. The methods of on-plant surveys, pitfall trapping, and canopy beating will be demonstrated. Data recording, sample storing and identification will be briefly explained and some small practical exercises can be run.

 

Rapid Biodiversity Assessment using Butterfly Transect Counts

Martin Wiemers (Helmholtz Centre for Environmental Research – UFZ, Halle, Germany)

Natural and semi-natural habitats are altered at increasing speeds due to land use and climate changes. Therefore rapid biodiversity assessments (RBA) are also becoming increasingly important to measure these changes. Insects represent the majority of species diversity in terrestrial habitats, and among them, butterflies have emerged as one of the best study groups due to relative ease of recording and determination. This is especially true for open grassland- or shrub-dominated habitats which are prevalent in the Zagori region. This field session will demonstrate RBA by using a standardized transect method in the surroundings of the field station, where more than 60 species of butterflies can be expected.

Student research project

Students will have to choose and develop a small research project. They will work in teams of three persons. Each team will have a supervisor to assist in formulating the research question, in designing an appropriate sampling methodology, and in the analysis and interpretation of the data collected. Student teams will have to work independently in the field and in the laboratory, and will be expected to present their project as 15 minute scientific presentation on the last day of the course. Simple field and laboratory equipment, as well as access to literature via the Internet will be available. Students may bring their own datasets if they want to work on those.
