L-1.1 | GENOMISCHE BASIS DER NISCHENEVOLUTION (2008-2011)

Verwandte Arten, wie auch verschiedene Populationen innerhalb einer Art, besetzen oft unterschiedliche klimatische Nischen und sind an ihre spezifischen Umweltbedingungen angepasst. Dies ist auf proximate, phänotypische Eigenschaften wie Temperaturtoleranz, Sauerstoffmangeltoleranz, Phänologie zurückzuführen. Ultimat, sind diese beobachtbaren ökologischen Unterschiede jedoch durch evolutive Veränderungen des Genoms bedingt. Über die ökologisch relevante genomische Basis von klimatischen Nischendifferenzen und deren Evolution ist jedoch noch sehr wenig bekannt.
Als Untersuchungsobjekte dienen uns hierbei die Zuckmücke Chironomus riparius, die Tigermücke Aedes albopictus, sowie die Schlammschnecke Radix balthica.
Durch die Kombination von Populationsgenetik, Common Garden Experimenten, Bestimmung physiologischer Unterschiede und Genexpressionsmuster lassen sich Aussagen über den Anteil der phänotypischen Plastizität bzw. evolutiver Unterschiede auf regulatorischer bzw. Proteinebene treffen. Das Ziel ist es, Gene bzw. ihre Regulation zu identifizieren, welche der Klimaanpassung einer spezifischen Art zugrunde liegen.
