Introduction to meta-analysis in conservation biology - Dr. Péter Batáry
Meta-analysis as a statistical tool for quantitatively synthesizing primary researches has gained a great momentum in ecology during this millenium. Ecological questions can be answered by systematic reviewsthat identifies, appraises, selects and synthesizes all high quality relevant research evidences. Systematic reviews often use meta-analysis as statistical technique to combine results of the eligible studies. During the workshop the following statistical methods and problems will be discussed and used with real ecological data: calculation of effect sizes, cumulative effect size and heterogeneity, fixed- and random-effect meta-analysis, biases.
Bees as biomonitoring agents - Dr. hab. Hajnalka Szentgyörgyi
Working in groups we will analyse various bee species/groups as possible biomonitoring agents. Based on literature we will plan monitoring activities based on the best fitted bee species for chosen areas and aims. Methods and techniques using bees will be presented. Partially based on real life data we will discuss the pitfalls and problems using such living organisms as bees for biomonitoring purposes.
