Symposium at NABS '08

To the FWGNA group,

Our good friend Bill Clark is co-organizing symposium on sampling low-density populations for the annual meeting of the North American Benthological Society next year in Salt Lake City, May 25 - 30. See Bill's message below. His [PDF] flier is available from the FWGNA site.

Bill and his colleague Leska Fore have been working on the endangered freshwater gastropods of the Snake River. They're hoping to share new methods, discuss unique sampling issues related to benthic species, and perhaps even break into a spontaneous discussion of the future of the ESA. Bill invited any of us who might wish to contribute a paper to this symposium to get in touch with Leska at the contact information below. Looks like a great opportunity!

We'll keep in touch,

Hi Rob:
I wonder if you could send this information for a symposium announcementout to your FWGNA group mailing list? I've attached a one page flyer and the basic information is also presented below in the email.

Thank you very much,
Bill Clark (and Leska Fore)

Quantitative Methods for Evaluating the Status of Threatened Species

Many of the benthic freshwater species identified to be at risk for extinction, e.g., mussels, clams, and snails, may be rare, unevenly distributed, or hard to detect. The focus of this session is on the quantitative methods used to assess population size, condition, orchange, such as mark-recapture, multi-stage survey sampling, and adaptive sampling. The goal of this special session is to bring together practitioners working with at risk populations to compare the limitations and advantages of various methods for different geographic settings and different types of organisms. Results from these studies can have enormous economic impact; for example, when power generation is limited at hydroelectric facilities to protect a threatened species. This session is not limited to any particular species group or any particular method of population assessment. General methods papers related to sampling are also welcome. Of greatest interest are studies in which the scientific results are embedded in the decision process forspecies conservation and protection.--
