Decomposition of Alnus glutinosa (alder) leaves was studied in a severely (site H4) and a moderately (site H8) heavy metal polluted stream in the former copper shale mining district of Mansfeld, Central Germany. Leaves at H8 had reduced fungal diversity and spore production but a high exponential de

β¦ Synopsis
Data gathered in the course of a large-scale study of the subjective effects of change in household exposure to traj~c noise have been used to test a model of response which is specifically intended to apply to noise control measures. Analysis shows that the model is no more and no less successful in predicting response to change than empirical dose-response relationships. This implies that the discrepancy between steady-state response and response after change in exposure is not explicable in terms of changes in either traj~c composition or the difference between annoyance threshoM and actual exposure.

The effects of 90 dB(A) noise exposure and/or a calculation task on plasma cyclic AMP concentrations (physiological index) and STAI-A-State scores (psychological index) in normal subjects are compared. Neither the plasma cyclic AMP concentration nor the STAI-A-State scores showed any significant cha
Here we describe a random effects threshold dose-response model for clustered binary-response data from developmental toxicity studies. For our model we assume that a hormetic effect occurs in addition to a threshold effect. Therefore, the dose-response curve is based on two components: relationship
