consideration of natural sources in a bacteria tmdl-lines of evidence, including beach microbial source tracking. | total maximum daily load (tmdl) stipulations remained unmet at a southern california beach despite a suite of management actions carried out since 2001, prompting exploration of a natural sources exclusion (nse) provision within the tmdl. quantitative microbial source tracking (mst) was employed from 2012 to 2015 to inventory sources of natural and anthropogenic fecal indicator bacteria (fib). data suggested fib exceedances could be traced to gulls based on gull marker prevalence and correlation ... | 2017 | 28633521 |
periorbital ecchymosis (raccoon eye) and orbital hematoma following endoscopic retrograde cholangiopancreatography. | endoscopic retrograde cholangiopancreatography (ercp) is a conventional technique for diagnosis and treatment of pancratobiliary diseases, which is associated with various complications, including pancreatitis, hemorrhage, cholangitis, perforation, and mortality. in our case, a 69-year-old woman with positive hepatobiliary symptoms underwent ercp, at the end of which a rare complication (raccoon eye) occurred, which was hypothesized to be due to amyloidosis, but the patient refused to complete t ... | 2017 | 28611566 |
can mhc-assortative partner choice promote offspring diversity? a new combination of mhc-dependent behaviours among sexes in a highly successful invasive mammal. | sexual selection involving genetically disassortative mate choice is one of several evolutionary processes that can maintain or enhance population genetic variability. examples of reproductive systems in which choosers (generally females) select mates depending on their major histocompatibility complex (mhc) genes have been reported for several vertebrate species. notably, the role of mhc-dependent choice not in mating contexts, but in other kinds of social interactions such as in the establishm ... | 2017 | 28141891 |
do large carnivores and mesocarnivores have redundant impacts on intertidal prey? | the presence of large carnivores can affect lower trophic levels by suppressing mesocarnivores and reducing their impacts on prey. the mesopredator release hypothesis therefore predicts prey abundance will be higher where large carnivores are present, but this prediction assumes limited dietary overlap between large and mesocarnivores. where dietary overlap is high, e.g., among omnivorous carnivore species, or where prey are relatively easily accessible, the potential exists for large and mesoca ... | 2017 | 28085962 |
do deer and raccoons defecate in the right place? fitness consequences of vertebrate seed dispersal for a deciduous forest herb. | precision of seed placement in a heterogeneous environment is often assumed to select for the evolution of animal-mediated dispersal systems, but this hypothesis has rarely been tested in a multivariate sense. we quantify the microsite fitness benefits of dispersal by white-tailed deer (odocoileus virginianus) and raccoons (procyon lotor) for mayapple (podophyllum peltatum), a shade-tolerant perennial herb, in deciduous forests of southeastern ohio, usa. micro-environmental variables were record ... | 2017 | 28078452 |
