Theoretical Ecology Lab Tea

The Theoretical Ecology Lab Teas are informal meetings where members of affiliated lab groups give talks on their current research and receive feedback from their audience. The talks are 30 minutes (20 minutes of presentation and 10 minutes of questions) and are scheduled generally on Wednesdays at 12:30 pm. All talks this semester will be held in Eno 209 unless stated otherwise.

This semester, talk schedules and email lists will be maintained by Kaia Tombak and Elise Myers. Please contact one of us to have your name added to the labtea email list so that you can receive reminders about upcoming meetings.

Lianas Affect Population Growth Rates of Tropical Trees Marco Visser

Lianas are increasing across the Neotropics and dramatically reduce the growth, survival, and fecundity of their host trees. Whether lianas affect tree species population growth rates differentially remains unknown. In this talk, I show how we used integral projection models to integrate liana effects across the life-cycle into total effects on population growth rates for 33 tropical tree species from Panama. Liana infestation decreased tree growth, survival and reproduction. Fast-growing tree species exhibited stronger declines in survival than did slow-growing species. Heavy liana infestation involving more than half of the host’s canopy reduced population growth rates by 1.9% per year. The reduction was greatest among fast-growing species, which showed much higher sensitivity to liana infestation. Lianas have strong differential effects on tree species populations, and thus ongoing increases in liana abundance are likely to alter tree species composition in Neotropical forests.
