This book was released on 2018 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to historic overharvest and habitat degradation, the alligator snapping turtle (Macrochelys temminckii) has experienced population declines throughout its range. Tishomingo National Fish Hatchery in southern Oklahoma began a captive head-start program for this species in 2000 and has since released over 1,400 turtles in the region. However, there has been a recurring trend of turtles growing faster after release than while in captivity. My research sought to investigate this pattern by determining: 1) the influence of housing enrichment and housing density on juvenile growth rates and stress in indoor enclosures, and 2) the effects of supplementing hatchlings with adult feces to enhance the gut microbiome. I found that the presence of floating mats in indoor tanks improved growth rates compared to other structural components. Group density did not affect average growth rates, but animals that were housed communally exhibited more variable growth than individuals housed without conspecifics present. When exposed to feces of adult conspecifics, hatchlings assimilated fiber components of their omnivorous diet more efficiently than those exposed only to deionized water or creek water. Based upon these results, flotant structures and exposure to microbes found in the feces of adult M. temminckii are recommended for future head-start efforts.

This book was released on 2010 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The alligator snapping turtle (Macrochelys temminckii) is a large freshwater turtle that inhabits many lotic water bodies in the Southeastern United States. The species consumes primarily fish but also consumes large amounts of vegetation including seeds of common persimmon (Diospyros virginiana), tupelos (Nyssa sp.), willow oak (Quercus phellos), and pecan (Carya illinoensis). Captive specimens of M. temminckii were fed samples of the above-mentioned seeds to assess how the species affects ingested seeds in order to evaluate the potential role this species may play as a seed disperser. The proportion of seeds defecated intact varied with species (57-99 %), was lowest in D. virginiana, and highest in N. aquatica. Ingestion reduced the percentage of seeds that germinated in comparison to uneaten controls in all species except Q. phellos where ingestion increased germination percent. Germination percent also decreased the longer seeds remained inside turtles. Ingestion reduced the germination rates of D. virginiana and N. aquatica seeds but increased germination rates for seeds of Q. phellos in comparison to uneaten controls. Due to fungal contamination, conclusions could not be drawn regarding the effect of ingestion on germination percent or rate of C. illinoensis seeds. This study suggests M. temminckii could potentially play some role as a disperser of Q. phellos and N. aquatica but is less likely for D. virginiana. Information regarding post-dispersal fates of seeds ingested by M. temminckii and other freshwater turtles is needed to evaluate the importance of freshwater turtles as dispersers of riparian and wetland vegetation.
