Bio: Elizabeth Wolkovich is an Associate Professor in Forest and Conservation Sciences and Canada Research Chair at the University of British Columbia. She runs the Temporal Ecology Lab, which focuses on understanding how climate change shapes plants and plant communities, with a focus on shifts in the timing of seasonal development (e.g., budburst, flowering and fruit maturity)---known as phenology. Her lab both collects new data on forest trees and winegrapes and collates existing data to provide global estimates of shifts in phenology with warming from plants to birds and other animals, and to understand how human choices will impact future winegrowing regions. Her research benefits from an interdisciplinary team of collaborators from agriculture, biodiversity science, climatology, evolution and viticulture, as well as from shared long-term datasets from across North America and Europe.
Abstract: Forty years ago ecology became increasingly focused on spatial structure and pattern, as researchers realized how fundamentally habitat loss and fragmentation reshapes populations and communities. A generation later, with spatial ecology firmly established as a cross-disciplinary, multi-scale field, anthropogenic climate change has forced ecology to revisit the importance of time. As warming stretches growing seasons around the globe, populations, species, communities and ecosystems are responding in turn. In this talk I outline two major challenges of temporal ecology with anthropogenic warming: stretched time and accelerated time. Focusing on plant phenology I show how longer growing seasons may re-assemble communities: first I focus on examples from invasion biology then I build to a more general theory. Next I show how how warming may make many biological processes that are dependent on thresholds appear to slow as warming continues. This is because warming accelerates biological time while calendar time stands still. I close by reviewing preliminary results that merge phenological cues with trait ecology to show that forests may assemble via their spring phenology.

Bio: Dr. Kate Laskowski is interested in investigating how evolution has shaped the developmental processes that generate behavioral individuality. She does this by generating replicate individuals and groups of the naturally clonal fish, the Amazon molly, allowing her to “replay the developmental clock.” Kate obtained her Bachelor’s of Science at the University of Maryland Baltimore County and her PhD from the University of Illinois where she worked under Alison Bell. She then moved to Berlin Germany to work at the Leibniz Institute of Freshwater Ecology & Inland Fisheries with Max Wolf and Jens Krause before joining the Department of Evolution & Ecology at the University of California Davis in 2019.
Abstract: Individual behavioral variation is ubiquitous across the animal kingdom. Explaining the continued generation and maintenance of such variation is a fundamental goal in behavioral and evolutionary ecology. Our research tests key predictions drawn from theoretical models about how genetic correlations and developmental processes can drive the emergence of consistent individual behavioral variation. This work has shown that competition for, and acquisition of, resources may play key roles in shaping behavior variation both on evolutionary and developmental timescales. Using the clonal Amazon molly and an innovative high-resolution tracking system we can follow and manipulate individual experience with salient environmental cues such as resource availability and relative risk. We can track the behavioral development of individual fish from birth in, up to now, unprecedented detail, allowing us to pinpoint exactly when and in response to which cues individuality emerges. Our results highlight that in order to fully explain the presence of individual behavioral variation we need a comprehensive conceptual framework that explicitly accounts for how natural selection has shaped the developmental process.
