Life History of the Freckled Crayfish Cambarus maculatus in two Missouri Streams

Duration

July 2013 - June 2016

Narrative

The goal of the proposed study is to document life history traits of C. maculatus populations. This would be done in two streams to account for possible variation due to local environmental conditions, and possibly for two years to account for interannual differences in timing of life cycle events. Specifically, we will describe these populations’ life cycles by collecting data on timing of reproductive-related events, size/age at sexual maturity, realized fecundity, egg size, and timing of recruitment of juveniles. We will also collect supplemental data on traits important to population management such as molting, sex ratios, size structure, maximum body size, longevity and growth.
