The Black Darter Crusade Continues
I've made more headway on this article, which now has a name (see below). A round of heavy editing and proofreading has it down to a total length of 37 pages. This includes a bunch of figures of histology images showing details of ovarian and testicular structures. Hopefully the editors see fit to include these figures in some form, the work that went into them damn near killed Rachel(!). I'm just about happy with it, and from here I show it to the two other co-authors who don't know yet that they are co-authors. Anyway, following is the title and abstract --
Reproductive Development in the Blacksided Snubnose Darter, Etheostoma duryi, in North Alabama
ABSTRACT
Reproductive development in the percid fish Etheostoma duryi (subfamily Etheostomatinae) was studied in two north Alabama populations in the Tennessee River drainage. Sites chosen for comparison were urban Town Creek, near downtown Athens in Limestone County, and rural Limestone Creek, in Madison County. Because of the small body size of this species the study uses a histological approach which has not been used in population studies of the Etheostomatinae. Microscopic and macroscopic methods were utilized to study gonadal development and investment. Town Creek fish were larger than Limestone Creek fish. Reproductive investment, as measured by gonadosomatic index, relative gonad mass and the proportionality coefficient, increased in both sites (and for both sexes) toward the time of peak spawning. However, there were no significant differences between the sites in reproductive output for either sex. Total number of oocytes differed significantly between populations, possibly attributable to differing body sizes. Clutch size and mass were not significantly different between sites. Reproductive maturation occurs from January until the peak in late March and April at both sites.
