The biological controls of soil carbon accumulation following wildfire and harvest in boreal forests: A reviewNARA Subscribed
Boreal forests are frequently subjected to disturbances, including wildfire and clear‐cutting. While these disturbances can cause soil carbon (C) losses, the long‐term accumulation dynamics of soil C stocks during subsequent stand development is controlled by biological processes related to the balance of net primary production (NPP) and outputs via heterotrophic respiration and leaching, many of which remain poorly understood...
Serum concentrations of antidepressants, antipsychotics, and antiepileptics over the bariatric surgery procedureNARA Subscribed
Purpose As a substantial proportion of bariatric surgery patients use psychotropic/antiepileptic drugs, we investigated the impact of this procedure on serum concentrations. Methods In a naturalistic, longitudinal, prospective case series, we compared dose-adjusted trough concentrations of antidepressants, antipsychotics, or antiepileptics in consecutive patients before and after bariatric surgery. Adherence to treatment over...
Radioxenon Releases from A Nuclear Power Plant: Stack Data and Atmospheric MeasurementsNARA Subscribed
An analysis of a data set consisting of 3 years of high time resolution radioxenon stack measurements from the three nuclear reactors at the Forsmark nuclear power plant in Sweden, as well as measurements of atmospheric radioxenon in Stockholm air, 110 km away, is presented. The main causes for the stack releases, such as the function of the xenon mitigation systems, presence of leaking fuel elements, and reactor operations su...
Response to Fornalski et al.NARA Subscribed
The effects of hatchery rearing density (conventional or one third of conventional density) and feeding regime (high or reduced dietary fat levels) on burst‐swim performance and oxygen transport capacity were studied in hatchery‐reared Atlantic salmon Salmo salar , using wild fish as a reference group. There was no effect of rearing density or food regime on swimming performance in parr and smolts. The maximum swimming speed o...
The parasitic copepod Lernaeocera branchialis negatively affects cardiorespiratory function in Gadus morhuaNARA Subscribed
The parasitic copepod Lernaeocera branchialis had a negative effect on cardiorespiratory function in Atlantic cod Gadus morhua such that it caused pronounced cardiac dysfunction with irregular rhythm and reduced stroke amplitude compared with uninfected fish. In addition, parasite infection depressed the postprandial cardiac output and oxygen consumption.
Behavioural fever boosts the inflammatory response in rainbow trout Oncorhynchus mykissNARA Subscribed
Behavioural fever, manifested as an increased preferred temperature, was shown in rainbow trout Oncorhynchus mykiss following an injection of bacterial lipopolysaccharide. Simulated behavioural fever, through a 2·5° C water temperature rise following bacterial lipopolysaccharide injection, enhanced the expression of the cytokine interleukin‐1 β , in comparison with an untreated group held at the initial temperature. The presen...
Cholinergic and adrenergic influences on the heart of the African lungfish Protopterus annectensNARA Subscribed
Cardiac cholinergic and adrenergic tones were determined in minimally instrumented African lungfish Protopterus annectens . Mean ±S.E. routine heart rate ( f H ) was 31·6 ± 1·4 beats min −1 , cholinergic tone was 34·6 ± 5·2% and adrenergic tone was 9·4 ± 2·3%, while the intrinsic f H after blockade of both adrenergic and cholinergic control systems was 39·1 ± 1·3 beats min −1 . It is demonstrated that routine cholinergic tone...
Poster abstractsNARA Subscribed
The maximum values for heart rate ( f H ), stroke volume ( V H ), cardiac output ( Q ) and myocardial power output, measured in vitro with a perfused heart preparation, as well as the isometric force‐frequency relationship for atrial and ventricular muscle strips, in triploid brown trout Salmo trutta were all comparable with established information for diploid rainbow trout Oncorhynchus mykiss . Therefore, it was concluded tha...
Behavioural and heart rate responses to food limitation and predation risk: an experimental study on rainbow troutNARA Subscribed
Food‐restricted rainbow trout Oncorhynchus mykiss maintained a lower basal heart rate than satiated fish, probably as a result of reduced metabolic rate. Food‐restricted fish were also more active during feeding and were more willing to take risks than satiated fish. Both satiated and food‐restricted fish were positioned lower in the tank after the predator attack. Heart rate increased more during feeding in the food‐restricte...
