This paper describes the evolution of a course developed to tie together many strands of activity encountered by students in the computer and mathematical sciences (CMS). The senior level course is required of all majors in our computer science, applied mathematics and statistics undergraduate degree programs. One of the primary purposes of the course is to refine writing and presentation skills needed for those who will later pursue individual research projects. Writing projects are organized around the theme of "Ethical Decision Making in the Computer and Mathematical Sciences". Numerous case studies are investigated. Additional topics in the course include designing resumes, starting a placement file, and a general introduction to the CMS culture. A course outline is given and various projects are discussed. This paper is based on a talk given by the authors at the joint national meetings of MAA/AMS in San Antonio on January 14, 1999.
Shortnose Chasmistes brevirostris and Lost River Suckers Deltistes luxatus endemic to the Klamath River Basin on the California-Oregon border have experienced dramatic population declines in parallel with many other Catostomid species. Captive propagation has become a key element of many endangered fish recovery programs, although there is little evidence of their success in restoring or recovering fish populations. A novel rearing program for Klamath suckers was initiated in 2016 with the goal of developing a husbandry strategy that better balances the ecological, genetic, and demographic risks associated with captive propagation. We collected 4,306 wild-spawned Klamath sucker larvae from a major spawning tributary May-June 2016 and reared them at a geothermal facility established through a partnership with a local landowner and aquaculture expert. Mortality during collection was less than 1%. Larvae were reared in glass aquaria for 17-78 days until reaching approximately 30 mm total length, upon which they were moved to round fiberglass tanks for 14-46 days or until reaching approximately 60 mm total length. Overall survival of larvae to ponding for final growout was 71%. Larval tank rearing survival was 98% for 37 days until an isolated fish health incident affected three aquarium populations, reducing survival to transfer to 75%. Survival after transfer to round fiberglass tanks for 14-46 days was 94%. This study outlines the first successful collection and early life history husbandry of wild-spawned endangered Klamath suckers that we are aware of.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
