Workshop on understanding and quantifying mortality in pelagic, early life stages of marine organisms: experiments, observations and models (WKMOR)
1. The workshop will consist of 2 days of talks (in plenary) and one day of structured discussions to prioritize research needs.
There will be 3-4 talks per theme session (see below), with 1-2 invited talks per session and the remainder contributed.
3. Posters will be displayed for the whole workshop and discussed during a poster session.
4. The poster boards will have the dimensions of 35' x 45' wide (landscape shaped).
Workshop co-Chairs will introduce the workshop goals and logistics. In addition, Dr. Edward Houde will review the history of mortality estimation and present challenges. His talk also will include a broad overview of the sources of mortality (e.g., disease, parasitism, starvation, predation, advective loss).
Confirmed speaker: Edward Houde
II. Laboratory studies: aquaculture, mesocosms, and small-scale interactions
Three to four speakers will discuss the biological sources of mortality in planktonic organisms, with emphasis on synthesis of previous studies, new methodologies and findings, and information on, or application to, meroplankton.
Confirmed speaker: Arild Folkvord
Confirmed speaker: David Bengtson
Confirmed speaker: Anne Berit Skiftesvik
III. Detecting and partitioning mortality in the field from planktonic stages to juveniles
Three to four speakers will address measuring biological and physical sources of mortality in planktonic organisms in the field, with emphasis on new methods, advection, and meroplankton, and discuss the larval-juvenile transition stage and young juvenile stage with respect to levels of mortality and how it relates to overall survival and recruitment potential, density dependence, etc.
Confirmed speaker: Claire Paris
Confirmed speaker: Richard Nash
Confirmed speaker: Mark Ohman
IV. Quantifying mortality: assumptions and sensitivity analyses
Three to four speakers will be asked to examine the assumptions behind the algorithms
equations we use to describe mortality as well as the sensitivity of these equations to input parameters.
Confirmed speaker: Wendy Gentleman
V. Numerical models: procedures for incorporating mortality and validation techniques
Three to four speakers will address the methods and challenges of incorporating mortality into coupled bio-physical models and possible methods for model validation.
Confirmed speaker: John Steele
VI. Revisiting the paradigms: linking mortality to recruitment
Three to four speakers will present their perspectives on the links between mortality and recruitment (in a general ecological,
not fisheries, sense), perhaps revisiting the "big theories" like match-mismatch, etc. in the light of what we know in the 21 century.
