The role of evolutionary processes for plant species responses to plant community diversity, plant history and soil history is discussed as a possible mechanism explaining the maintenance of biodiversity and the strengthening of biodiversity effects on ecosystem functioning over time. In this subproject we focus on evolutionary responses of plant species, which should be measurable in the phenotype and at the molecular level to pursue the following objectives:<\/p>\n\n\n\n

Cultivation of phytometers for the field experiment
(March 2020) <\/figcaption><\/figure><\/div>\n\n\n\n

(1) We will test if phenotypic responses are heritable and\nadaptive to local plant community diversity, plant and soil history, or if they\nreflect adaptive phenotypic plasticity due to differences in the actual growth\nenvironment.<\/p>\n\n\n\n

(2) We will\nanalyze how within-species variation in phenotypic trait expression is related\nto genetic and epigenetic differences.<\/p>\n\n\n\n

(3) We will assess whether epigenetic variation is mainly under genetic control or to what extent patterns of epigenetic differentiation are reversible under different environmental conditions or result from heritable epigenetic differentiation.<\/p>\n\n\n\n

Common garden experiment with Taraxacum officinale

First, we chose eight plant species to conduct a phytometer experiment with offspring of seed families collected in the 17-year old plant\ncommunities to test\nfor adaptive phenotypic responses. Second, we use genotypes of the model\nspecies Plantago lanceolata<\/em> with a\nselection history in low- and high-diversity communities as phytometers in the Ecotron Experiment to test if genotypes show adaptive phenotypic plasticity and\nepigenetic variation in response to the actual environment. Third, we quantify\nevolutionary changes in response to plant diversity at the genetic, epigenetic\nand phenotypic level using the apomictic model species Taraxacum officinale<\/em> in a common garden.<\/p>\n","protected":false},"excerpt":{"rendered":"
