LUMS: Life history under multiple stressors

In this project we seek to understand the effect of multiple stressors on life history traits. We use copepods as model organisms.

Copepod for studying life under multiple stressors,

Temora longicornis

About the project

We want to develop a coherent platform for combining theoretical, experimental and field- based studies of life history evolution of ectotherms. This will include a common framework for constructing, performing, and analyzing data from controlled experiments with life history traits as endpoints. Several spatial and organizational scales will be investigated, from sub- cellular, individual, population, and species level, both under laboratory and field conditions. Observations will be developmental (image analysis of developmental stages, flow cytometry) as well as molecular (genome size, gene expression, epigenetic).
 
One post doc and one PhD student are directly funded by LUMS. There are synergies with many of the other projects of the group members.

Objectives

We quantify life history changes due to environmental stress imposed by variation in temperature, nutrition, predation risk, and toxicants, using survival, fecundity, energy allocation, body size and behavior as endpoints.

Sub-projects

  • Tradeoffs between growth and development in relation to temperature, food supply, and predation risk.  (One Post Doc)

  • Effects of exposure to toxicants as one of multiple stressors on energy allocation, longevity, development and reproductive output. (One PhD student)

Financing

Financed by the Deparment of biosciences, as a prioritized research group (IBV-satsingsmiljø)
