| was the giant short-faced bear a hyper-scavenger? a new approach to the dietary study of ursids using dental microwear textures. | dramatic environmental changes associated with global cooling since the late miocene, and the onset of glacial-interglacial cycles in the pleistocene served as a backdrop to the evolutionary radiation of modern bears (family ursidae). these environmental changes likely prompted changes in food availability, and triggered dietary adaptations that served as motive forces in ursid evolution. here, we assess correspondence of dental microwear textures of first and second lower molars with diet in ex ... | 2013 | 24204860 |
| novel finding of widespread occurrence and accumulation of bisphenol a diglycidyl ethers (badges) and novolac glycidyl ethers (noges) in marine mammals from the united states coastal waters. | bisphenol a diglycidyl ether (badge)- and bisphenol f diglycidyl ether (bfdge)-based epoxy resins have a broad range of applications, including serving as inner coatings of food and beverage cans and as protective coatings in marine construction. prior to this study, no studies had examined the occurrence and bioaccumulation of badges or bfdges in aquatic organisms. in this study, badge, bfdge, and nine of their derivatives were determined in 121 tissue (liver, kidney, blubber, and brain) sample ... | 2016 | 26800265 |
| elevated accumulation of parabens and their metabolites in marine mammals from the united states coastal waters. | the widespread exposure of humans to parabens present in personal care products is well-known. nevertheless, little is known about the accumulation of parabens in marine organisms. in this study, six parabens and four common metabolites of parabens were measured in 121 tissue samples from eight species of marine mammals collected along the coastal waters of florida, california, washington, and alaska. methyl paraben (mep) was the predominant compound found in the majority of the marine mammal ti ... | 2015 | 26379094 |
