Interpretation. 1  Opiates are the natural or synthetic drugs that have a morphine-like pharmacological action. 2  Heroin (diacetylmorphine) is a synthetic opiate made from morphine and is rarely detectable in body fluids. 3  Ingestion of bakery products containing poppy seeds can also cause morphine to be excreted in urine.
Western pond turtles are omnivorous and most of their animal diet includes insects, crayfish and other aquatic invertebrates. Fish, tadpoles, and frogs are eaten occasionally, and carrion is eaten when available. Plant foods include filamentous algae, lily pads, tule and cattail roots.
In addition, the western pond turtles may face competition from other turtle species. While the Clackamas County survey found no pond turtles, it did find two other species: the native western painted turtle and the invasive red-eared slider. The sliders often get released as unwanted pets and proceed to compete with native turtles for food and nesting and basking sites.
