Jan Bengtsson
Min forskning handlar om biologisk mångfald, ekosystemtjänster och organismsamhällens ekologi i produktionsekosystem och -landskap (jordbruk och skog), och om kopplingen mellan populations/samhälls-ekologi och ekosystemprocesser, såväl i teori som i empiriska studier och i tillämpade sammanhang. Jag är också medlem i styrgruppen för Framtidens Lantbruk.

Presentation

Jag har studerat metapopulationsynamik och artinteraktioner hos vattenloppor (Daphnia) sedan det tidiga 1980-talet.  Tack vare mina eminenta och kunniga medarbetare och doktorander har jag också studerat biologisk mångfald och ekosystemtjänster (huvudsakligen biologisk kontroll av skadegörare och pollinering, samt produktion och kolets dynamik) i jordbruks- och skogslandskapet, rumslig variation i markdjurs-samhällen, hur brand påverkar markorganismer, och hoppstjärtars (Collembola) diversitetsmönster och ekosystemprocesser i Sydafrikas megadiversa Fynbos-biom. Vi har studerat hur viktigt biodiversitet är för ekosystemfunktion och hur man kan förvalta landsakp för att bevara och sköta biologisk mångfald och ekosystemtjänster, avvägningar mellan olika ekosystemtjänster, scenarier för framtidens jordbruk, m.m.
