PICES Annual Meeting

Nereus Fellow at Princeton Colleen Petrik will be giving a plenary talk entitled “The Response of Fisheries Production to Natural and Anthropogenic Forcing: Past, Present and Future” at the PICES Annual Meeting in San Diego. The talk presents a mechanistic model to represent immature and mature stages of forage fishes, large pelagic fishes, and large demersal fishes, as well as preliminary of fish biomass under (1) pristine non-anthropogenic historical forcing (no anthropogenic CO2, no fishing), (2) historical climate without fishing, (3) historical climate with fishing, (4) and projected business-as-usual climate and fishing.

Shifting seasonal cycles: Rebecca Asch completes fellowship

In spring, as the plant buds push up through the ground and the days get warmer and longer, the baby salmon fry hatch out of their eggs and start swimming and feeding. At this time, their food – phytoplankton – should also bloom. But due to climate change-induced warming, the fry of many fishes, such as salmon, are coming out earlier or later, as are the phytoplankton blooms, which can cause a mismatch between when the food is available and when the fry need it.

IPBES Report: Methodological Assessment of Scenarios and Models of Biodiversity and Ecosystem Services

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) released their Methodological Assessment of Scenarios & Models of Biodiversity & Ecosystem Services, for which Nereus Director of Science William Cheung was a coordinating lead author, as well as a contributing author for Chapter 5 “Modelling consequences of change in biodiversity for nature’s benefits to people” (200-243).
