Seasonal diatom variability and paleolimnological inferences – a case study
The seasonality of physical, chemical, and biological water variables is a major characteristic of temperate, dimictic lakes. Yet, few investigations have considered the potential information that is encoded in seasonal dynamics with respect to the paleolimnological record. We used a one-year sequence of diatoms obtained from sediment traps and water samples, as well as the sedimentary diatom r...

متن کاملA sediment record of trophic state change in an Arkansas (USA) reservoir
Reservoir sediments are used cautiously in paleolimnological studies because of dating uncertainties, possible sediment disturbances and even concerns that indicators of trophic status may behave differently in reservoirs as opposed to natural lakes. We measured loss on ignition (LOI), carbon to nitrogen ratio (C:N), diatom abundance, total nitrogen (TN), total phosphorus (TP), TN:TP ratio, and...
متن کاملAssessment of Decisional Conflict about the Treatment of Trigger Finger, Comparing Patients and Physicians
Background: As an early step in the development of a decision aid for idiopathic trigger finger (TF) we were interested in the level of decisional conflict experienced by patients and hand surgeons. This study tested the null hypothesis that there is no difference in decisional conflict between patients with one or more idiopathic trigger fingers and hand surgeons. Secondary analyses address ...
