Awesome Chelydra Album and Music Offers

The name "snapping turtle" conjures up images of powerful, prehistoric-looking beasts that lurk in the dark waters of local swimming holes. Beyond its status as childhood legend, Chelydra serpentina is one of the most interesting reptiles of the New World. One of our largest turtles, this animal weighs up to thirty-five pounds, lays as many as one hundred eggs and can deliver a nasty bite. Due to its wide distribution, abundance, and large reproductive output, the snapping turtle has become one of the most extensively studied species of reptiles.

This volume synthesizes all that is known about the common snapping turtle to provide an up-to-date and comprehensive resource on the species' evolution, physiology, behavior, and life history. Anthony C. Steyermark, Michael S. Finkler, Ronald J. Brooks, and a team of experts detail the systematics, energetics, growth patterns, sex determination, and population genetics of snapping turtles and devote special attention to the fossil record of the snapping turtle family Chelydridae.

The first broad biological treatment of the common snapping turtle, this is the definitive reference for anyone working with or interested in this fascinating reptile.

What if a fed-up American atheist and "godless liberal" became a newspaper opinion columnist? This unique compilation answers that question, and demonstrates how an unapologetically secular perspective can go mainstream, reminding non-believers they're not alone, while simultaneously reaching a largely Christian audience. Exploring the power of "preaching to the converted," this motivating collection challenges other atheists, secularists, agnostics, and freethinkers to become vocal and involved in their own local media, adding a rational voice to the daily dialogue taking place in newspapers across the country. "A 21st Century Rationalist in Medieval America" is a collection of newspaper opinion columns, and other essays, written between 2002 and 2006. The subject matter includes: American politics, the media, religion, atheism, evolution and creationism, the Bush administration, science education, free will, gay marriage, religious conservatives, the Bible, morality, and the Iraq war..

Description:
The John Heinz National Wildlife Refuge is subject to pollution from multiple sources. We studied development of snapping turtle (Chelydra serpentina) and painted turtle (Chrysemys picta) embryos from the refuge from 2000 through 2003. Mean annual deformity rate of pooled painted turtle clutches over four years ranged from 45 to 71%, while that of snapping turtle clutches ranged from 13 to 19%. Lethal deformities were more common than minor or moderate deformities in embryos of both species. Adult painted turtles had a higher deformity rate than adult snapping turtles. Snapping turtles at JHNWR had high levels of PAH contamination in their fat. This suggests that PAHs are involved in the high level of deformities. Other contaminants may also play a role. Although the refuge offers many advantages to resident turtle populations, pollution appears to place a developmental burden on the life history of these turtles. urtles. .

Description:
Polycyclic aromatic hydrocarbons (PAHs) are toxic compounds found in the John Heinz National Wildlife Refuge in Philadelphia, Pennsylvania. We assessed the impact of PAHs and crude oil on snapping turtle development and behavior by exposing snapping turtle eggs from the Refuge and from three clean reference sites to individual PAHs or a crude oil mixture at stage 9 of embryonic development. Exposure to PAHs had a significant effect on survival rates in embryos from one clean reference site, but not in embryos from the other sites. There was a positive linear relationship between level of exposure to PAHs and severity of deformities in embryos collected from two of the clean reference sites. Neither righting response nor upper temperature tolerance (critical thermal maximum, CTM) of snapping turtle hatchlings with no or minor deformities was significantly affected by exposure to PAHs. .
