Population influences desiccation tolerance in an invasive aquatic snail, (Tateidae, Mollusca).

Traits in species that influence invasion success may vary in populations across its invaded range. The aquatic New Zealand mud snail, , reproduces parthenogenetically in its invaded range, and a few distinct clonal genotypes have been identified in North America. Much of the spread of the snail in North America has been the result of unintentional overland transport by recreational water users.

Topics most predictive of favorable overall assessment in outpatient radiology.

Background: Patients' subjective experiences during clinical interactions may affect their engagement in healthcare, and better understanding of the issues patients consider most important may help improve service quality and patient-staff relationships. While diagnostic imaging is a growing component of healthcare utilization, few studies have quantitatively and systematically assessed what patients deem most relevant in radiology settings. To elucidate factors driving patient satisfaction in outpatient radiology, we derived quantitative models to identify items most predictive of patients' overall assessment of radiology encounters.
