Reproductive Biology Of Thamnophis Sauritus Sackenii (Kennicott) (Reptilia:Serpentes:Colubridae) From East-Central Florida, Steven. Myers
Reproductive Biology Of Thamnophis Sauritus Sackenii (Kennicott) (Reptilia:Serpentes:Colubridae) From East-Central Florida, Steven. Myers
Retrospective Theses and Dissertations
Peninsula ribbon snakes, Thamnophis sauritus sackenii, were collected for 14 months. Of 90 individuals collected and examined, 42 were females, 29 were males, and 19 were neonates. Females had a larger body length than did males. The smallest, sexually mature female had a snout-vent length of 428 mm. Mating occurred from March through May. Parturition occurred from June through October. Vitellogenesis began in spring and ovulation occurred between April and May. Spermatogenic activity occurred from August through December and testes were regressed during other months.

Surgical Sterilization Of Grass Carp (Ctenopharyngodon Idella Val.), David H. Clippinger
Surgical Sterilization Of Grass Carp (Ctenopharyngodon Idella Val.), David H. Clippinger
Retrospective Theses and Dissertations
In November, 1983, 93 sexually immature and 33 mature grass carp (Ctenopharyngodon idella Val.) were surgically sterilized by clipping the gonaduct or removing a section of the ovaries of testes through a ventral incision between the pelvic girdle and the vent. No mortality occurred from this procedure. After six months (May, 1984), 95.7% of the immature and 100% of the mature grass carp had at least some gonadal tissue regeneration. Fifty-nine percent of the immature fish regenerated a pathway for the eggs or milt to enter the environment. Artificial spawning of the mature female grass carp was 66.7% successful. Over …
Life History Tactics Of The Sailfin Molly (Poecilia Latipinna) In Contrasting Environments, Helen L. Large
Life History Tactics Of The Sailfin Molly (Poecilia Latipinna) In Contrasting Environments, Helen L. Large
Retrospective Theses and Dissertations
Life history tactics of three Central Florida populations of Poecilia latipinna were compared to those predicted by life history selection theory. The three populations were sampled monthly for one year. At each sampling period a series of physicochemical measurements were taken to determine the degree of spatial and temporal environmental heterogeneity within each site. Life history traits determined for each population included size at maturity, size specific fecundity, reproductive effort, and length, weight, and condition of offspring. The population inhabiting the most variable environment was characterized by smaller size at maturity, lower size specific fecundity, lower overall reproductive output, and …
