This Festschrift collects an array of work inspired, influenced, instigated by the work of Teja Tscharntke, and/or by him personally. To locate the influence Teja may have had on the reader, the Festschrift starts with an academic biography. The contributions are organised along the five themes we identified as describing Teja Tscharntke’s work: (i) landscape ecology; (ii) pollination; (iii) biocontrol (and multitrophic interactions more widely); (iv) food security; and (v) socio-ecological systems. Also, the back-matter contains a bibliography of Teja’s own publications (at time of editing).
