CEES Friday seminar: Is timing everything? Marine plankton phenology in a changing climate

Abstract

Phenology, the study of annually recurring biological phenomena in relation to climate conditions, is particularly useful in examining the system responses to environmental disturbances. Such studies have been conducted extensively in terrestrial and freshwater systems, and have received increasing attention for coastal and open ocean systems. In this talk, I will present case studies of marine plankton phenology in both temperate and polar systems. The first part will be focused on the drivers responsible for phytoplankton phenological shift, and the second part on the implications for the population dynamics and biogeography of calanoid zooplankton species. Both empirical analyses and quantitative modeling approaches have been used in those studies.

The results highlight that correctly identifying specific drivers in a dynamic system is important for establishing links with ‘near-field’ and ‘far-field’ climate forcing; and that biogeography is sensitive to phenological variability, especially in high-latitude systems where organisms often need to meet their critical developmental threshold within a short growing season.
