Sept 2021: My colleague Dr Jesus Villellas from our Trinity College Dublin days has recently published the next chapter in the Plantago lanceolata story, through the PLANTPOPNET network, led by Prof. Yvonne Buckley. Jesus is now at Museo Nacional de Ciencias Naturales in Madrid, Spain.
Combining a multi-treatment greenhouse experiment with global observational field data of the short-lived herb Plantago lanceolata, we (1) disentangled genetic and plastic responses of functional traits to environmental drivers and (2) assessed how genetic differentiation and plasticity shape observational trait–environment relationships. Reproductive traits (more closely related to fitness) showed distinct genetic differentiation that largely determined observational patterns. Vegetative traits showed instead higher plasticity and opposite genetic and plastic responses, masking the genetic component underlying field-observed trait variation.
