Preliminary scope of work

Kritické zhodnocení současného stavu výzkumu strategií opylování orchidejí. Analýza výhod a nevýhod šálivých strategií z hlediska reprodukčního úspěchu rostliny. Zvláštní důraz by měl být věnován vlivu velikosti květenství na reprodukční úspěch a následně na fitness rostlin. Modely tohoto vztahu by měly být prozkoumány a kriticky porovnány. Očekává se, že budou nastíněny cesty vpřed v tomto druhu modelování.

Preliminary scope of work in English

A critical evaluation of the state-of-the-art of the research of orchid pollination strategies. Analysis of the pros and cons of deception in terms of the reproductive success of the plant. A special emphasis should be devoted to the effect of floral display on reproductive success and subsequently on plant fitness. Models of this relationship should be reviewed and critically compared. Ways forward in this kind of modelling are expected to be outlined.
