Temporal Ecology Lab

Wolkovich group at Arnold Arboretum



Welcome to the Temporal Ecology Lab. We’re focused on understanding how global changes alter the temporal assembly and disassembly of communities. Much of the research in the lab centers on understanding recent shifts in `biological spring,' advances in the timing of plants’ leafout and flowering that have occurred in many regions of the globe with climate change.

We’re primarily field ecologists who use whatever approach best fits the question at hand. As such most of us split our time between collecting and analyzing field data, working on meta-analyses of contemporary and historical data or setting up experiments in and out of doors.


Current projects in the lab use tree cores, growth-chamber studies, winegrape harvest data and more to understand the temporal dimension of populations, communities and ecosystems. We’re geographically based at the Arnold Arboretum at Harvard University in Boston. Academically we’re based in the department of Organismic & Evolutionary Biology.
