An strange garden at U of T Mississauga is drawing inquiries from curious passer - by . The immature lawn between Alumni House and Mississauga Road has been cover with black landscape textile and dotted with more than 450 livid trefoil plants .
The plant start from seeds collected from more than 100 locations across Europe and North America , and are part of a pioneering study to try out the adaptation of lily-white clover in both its native and introduced ranges . superposable gardens will be established at mate institution in Louisiana , France and Sweden .

The project is led by PhD student Lucas Albano and atomic number 27 - investigator Marc Johnson , associate prof of biological science and manager of the Centre for Urban Environments . The evolutionary ecologists will study how the invasive whitened clover plants have evolved in different locations , and how the plants are adapting to climate change in the nowadays . “It ’s really unusual that we can test this way , ” read Johnson . “ There are very few experiments that empirically demo that the plants can adapt to climate change . ”
White clover thrives around the world , but is a comparatively late neophyte to North America . The invading flora was introduced , probable as stock fresh fish , by European settlers about 500 year ago .
“ trefoil is a model species , ” says Albano . “ The results of this common garden subject could allow us potentially to bridge over to other species and enforce our result more broadly across the plant world . ”
Albano and Johnson will build on previous enquiry from the 1950s that find white trefoil plants in Europe had evolve adaptive trait specific to localisation and climate . One such adaptation is cyanogenesis , a potent chemical substance defence system discover only in tender clime clovers that deters herbaceous pests from eating the leaves . Clover that has adapted to cold placement does not carry the trait .

Over the next 18 months , Albano and Johnson will track plant growth , blossom and seed production and chemical substance defence traits displayed by plant .
“ Two summers render the flora a prospicient sentence to adjust and flourish – or not thrive – under natural status , ” Albano says . “ We will test each plant for whether it ’s bring about atomic number 1 cyanide or not , which will countenance us to need more questions about what ’s causing them to be more or less successful . ”
The researchers trust to hit a better discernment of whether adaptative phylogenesis in plant life can hold the effect of mood change , and whether evolution help the works succeed in new environments .
“ We would look to see that plants from nearby ( Ontario ) locations , like Acton or Cayuga , would do best because they would be highly adapted to the climate closest to UTM , and that a plant grown further from its altered environs would be less successful , ” articulate Albano .
If plants from a more southerly location such as Ohio do well in the U of T Mississauga garden , he say , it could show how works might adapt to a thaw mood in the future .
Albano is also interested in how European plants will fare when compared to clovers adapted to North American growing conditions .
“ And what happens when we transport North American clovers back to Europe ? ”
Collaborating institutions admit the University of Louisiana at Lafayette , Le Centre National de la Recherche Scientifique and Sveriges lantbruksuniversitet ( Swedish Agricultural University ) in Sweden . support for the study is allow for by the National Sciences and Engineering Research Council and the Canada Research Chairs programme .
