ESCALATION AND EXTINCTION SELECTIVITY: MORPHOLOGY VERSUS ISOTOPIC RECONSTRUCTION OF BIVALVE METABOLISM

Dietl, G. P., Kelley, P. H., Barrick, R., & Showers, W. (2002, February 1). Evolution.

By: G. Dietl n, P. Kelley*, R. Barrick n & W. Showers n

MeSH headings : Animals; Biological Evolution; Fossils; Geologic Sediments; Maryland; Mollusca / anatomy & histology; Mollusca / classification; Mollusca / growth & development; Mollusca / metabolism; Oxygen Consumption; Species Specificity
topics (OpenAlex): Marine Bivalve and Aquaculture Studies; Isotope Analysis in Ecology; Marine Biology and Ecology Research
TL;DR: It is predicted that some morphologically non‐escalated species in previous tests of extinction selectivity should be reclassified as escalated because of their fast shell growth rates, which are positively correlated with metabolic rate and thus are potential indicators of level of escalation.

Oxygen isotope variability in bones of wild caught and constant temperature reared sub-adult American alligators

Stoskopf, M. K., Barrick, R. E., & Showers, W. J. (2001, June 1). Journal of Thermal Biology.

By: M. Stoskopf n, R. Barrick n & W. Showers n

author keywords: bone; heterothermy; oxygen isotopes; alligator; reptile; thermoregulation
topics (OpenAlex): Fish Ecology and Management Studies; Physiological and biochemical adaptations; Isotope Analysis in Ecology
TL;DR: The thoracic vertebra had the highest mean delta18O(BP) ( per thousandSMOW), indicative of lower temperatures, and the lowest variability of bones in both groups of alligators, whereas the tibia was one of the warmest and more variable bones inboth groups ofalligators. (via Semantic Scholar)

topics (OpenAlex): Paleontology and Evolutionary Biology; Evolution and Paleontology Studies; Ichthyology and Marine Biology
TL;DR: Computerized tomography scans of a ferruginous concretion within the chest region of an ornithischian dinosaur reveal structures that are suggestive of a four-chambered heart and a single systemic aorta, which suggests the existence of intermediate-to-high metabolic rates among dinosaurs.

The thermoregulatory functions of theTriceratopsfrill and horns: heat flow measured with oxygen isotopes

Barrick, R. E., Stoskopf, M. K., Marcot, J. D., Russell, D. A., & Showers, W. J. (1998, December 28). Journal of Vertebrate Paleontology.

By: R. Barrick n, M. Stoskopf n, J. Marcot*, D. Russell n & W. Showers n

topics (OpenAlex): Physiological and biochemical adaptations; Evolution and Paleontology Studies; Bat Biology and Ecology Studies
TL;DR: The frill and horn cores of Triceratops were used as thermoregulatory structures with the horn cores interpreted as being especially important in the stabilization of brain temperatures at extreme ambient temperatures and the frill serving a more consistent role in body temperature regulation.
