Andy Purvis, Prof.
Andy Purvis is a Re­search Leader and In­di­vid­ual Mer­it Re­searcher at the Nat­ur­al His­to­ry Mu­se­um in Lon­don. His group’s re­search most­ly us­es sta­tis­ti­cal mod­el­ling of large, het­eroge­nous da­ta com­pi­la­tions to tack­le a wide range of ques­tions in con­ser­va­tion, ecol­o­gy and evo­lu­tion. He leads the PRE­DICTS (Pro­ject­ing Re­spons­es of Eco­log­i­cal Di­ver­si­ty In Chang­ing Ter­res­tri­al Sys­tems) project, which mod­els glob­al­ly how land use and re­lat­ed pres­sures im­pact lo­cal ter­res­tri­al bio­di­ver­si­ty and projects from these mod­els to in­fer past, present and pos­si­ble fu­ture bio­di­ver­si­ty. Among oth­er find­ings, PRE­DICTS showed that we have crossed the pro­posed plan­e­tary bound­ary for bio­di­ver­si­ty, but that pro­tect­ed ar­eas re­tain high­er lo­cal bio­di­ver­si­ty than un­pro­tect­ed sites, and that the land-use changes in the dif­fer­ent Shared So­cioe­co­nom­ic Path­way sce­nar­ios will cause di­ver­gent tra­jec­to­ries for bio­di­ver­si­ty. He was a Co­or­di­nat­ing Lead Au­thor on the IPBES Glob­al As­sess­ment, and was award­ed the Marsh Award for Ecol­o­gy by the British Eco­log­i­cal So­ci­ety in 2019.

Jens-Christian Svenning, Prof.

Pro­fes­sor Sven­ning re­ceived his PhD in trop­i­cal ecol­o­gy in 1999. He has since then worked broad­ly in ecol­o­gy and bio­geog­ra­phy, with par­tic­u­lar in­ter­est in the ba­sic mech­a­nisms un­der­ly­ing bio­di­ver­si­ty dy­nam­ics and eco­log­i­cal com­mu­ni­ty as­sem­bly, bio­di­ver­si­ty-cli­mate re­la­tions, the ecol­o­gy and di­ver­si­ty of trees and megafau­na, and in hu­man-bio­di­ver­si­ty re­la­tions from pre­his­tor­i­cal times to the fu­ture.

Giv­en our cur­rent An­thro­pocene chal­lenges and the bio­di­ver­si­ty and cli­mate change crises in par­tic­u­lar, pro­fes­sor Sven­ning has cou­pled his fun­da­men­tal re­search to ap­plied re­search in con­ser­va­tion, restora­tion and rewil­d­ing, and in eco­log­i­cal fore­cast­ing and re­mote-sens­ing-based mon­i­tor­ing, as well as de­vel­oped a re­search agen­da on the ecol­o­gy of the hu­man species and our clos­est rel­a­tives.

David Tilman, Prof.

David Tilman is Re­gents Pro­fes­sor and McK­night Pres­i­den­tial Chair in Ecol­o­gy at the Uni­ver­si­ty of Min­neso­ta, and Dis­tin­guished Pro­fes­sor in the Bren School of En­vi­ron­men­tal Sci­ence and Man­age­ment at the Uni­ver­si­ty of Cal­i­for­nia San­ta Bar­bara. Tilman is an ex­per­i­men­tal and the­o­ret­i­cal ecol­o­gist whose long-term ex­per­i­ments and re­lat­ed the­o­ry showed that, and why, bio­di­ver­si­ty is a ma­jor de­ter­mi­nant of ecosys­tem sta­bil­i­ty, pro­duc­tiv­i­ty, car­bon stor­age and sus­cep­ti­bil­i­ty to in­va­sion.

Much of his re­cent work fo­cus­es on agri­cul­ture, and seeks ways to pre­serve bio­di­ver­si­ty and pre­vent ex­tinc­tions while still pro­vid­ing se­cure and healthy di­ets for all the peo­ple of the Earth.
