Science For Everyone – Effect of Buckthorn on Frog Populations
May 15, 2018 @ 7:00 pm - 8:30 pm
Dr. Roberto Brenes will discuss the relationship between the presence of the invasive common buckthorn and the decline of amphibian populations in SE Wisconsin. The common buckthorn, which is widely distributed in southeastern Wisconsin its known for producing a secondary metabolite called emodin that produced deformation and mortality on early developing larvae of some amphibian species. Their research at Carroll University in Waukesha, shows that the effect of the emodin depends on the species and developmental stage of the exposed amphibians. Hence, areas where buckthorn is abundant will see declines in certain species population and the increase or permanence of other species, affecting the ecosystem balance.
Science for Everyone is a monthly lecture series sponsored by Riveredge and the Friends of LacLawrann Conservancy and the UWM Field Station. The series covers a wide range of topics including natural history, science, public policy and the environment. The programs are for the curious of any age and are open to the public. The lectures will both educate and entertain.
