Invasive Plant Thrives Because It Adapts Quickly To Local Climates
2013-10-17 14:25:07

University of Toronto University of Toronto research has found that purple loosestrife – an invasive species that competes with native plants for light and nutrients and can degrade habitats for wildlife – has evolved extremely rapidly, flowering about three weeks earlier as it has spread to northern Ontario. This has allowed populations of the species to thrive in the colder climate with a more than 30-fold increase in seed production. "The ability of invasive species to rapidly...

Acting through links between four trophic levels and across two ecosystems, purple loosestrife altered life in nearby ponds An elementary school science activity asks children who have each been assigned a wetland plant or animal to connect themselves with string and tape to other “organisms” their assigned plant or animal interacts with in some way. Once an ecosystem web has been created, the teacher describes an event that affects one “organism.” That...

The flowering plant - purple loosestrife - has been heading north since it was first introduced from Europe to the eastern seaboard 150 years ago. This exotic invader chokes out native species and has dramatically altered wetland habitats in North America. But it turns out it may have a vulnerability after all: the northern climate. Canadian scientists have found that adapting to the Great White North carries a severe reproductive penalty that may limit its spread. Purple loosestrife (Lythrum...
