As a result of factors such as global warming, habitat destruction, and species introduction, amphibians are declining worldwide. No one, however, has analyzed the status of polymorphic amphibian species at a national or continental scale, although some local reports exist. Our aim was to report on the loss of intraspecific heterochrony as a loss to diversity in determining the consequences of fish stocking on European populations of paedomorphic newts. Paedomorphosis is a polymorphism in which larval traits are retained in the adult stage. We surveyed 39 paedomorphic populations of the alpine ( Triturus alpestris) and palmate ( T. helveticus) newts, all but one of which initially occupied fishless ponds and lakes in France, Italy, Slovenia, Bosnia, Montenegro, and Greece. Exotic fishes were found in 44% of the studied aquatic habitats, with a 100% presence in Montenegro. At all sites paedomorphs disappeared and metamorphs declined. Only fish explained these population changes because alternative factors such as drying were not significant. More catastrophically, fish introductions occurred in habitats known to support the largest populations of newts and even some endemic subspecies. If management and legislative measures are not taken to stop fish stocking, protect paedomorphs as conservation units at national and international levels, and restore natural habitats, all the largest paedomorphic populations may disappear in the near future. Their disappearance would represent a loss of one of the rare, fascinating examples of intraspecific heterochrony. [less ▲]

The results of estimating production functions augmented by various measures of workers' participation on a large enterprise level data set of French cooperatives are reported. Value added is found to be an increasing function of participation in profits, in collective membership and in ownership, even when a wide assortment of enterprise specific and environmental factors are taken into account. This finding is very robust, surviving tests between alternative specifications of technology, for reverse causality, for simultaneous equation bias and for multicollinearity. The typical productivity effect from participation, however, is small, around 5% of output. The results suggest that Western policymakers should investigate ways to increase workers' participation in capital stakes and profit shares. [less ▲]

Tested 15 male smokers (aged 18-25 yrs) in a within-Ss design to determine the influence of a transdermal patch of 21 mg nicotine on vigilance. Ss were tested on the Rapid Visual Information Processing test 1.3, 3 and 6.3 hrs after patch application, to verify the involvement of the dose of nicotine on the performance. The results confirm and extend the knowledge on the increasing effects of nicotine on vigilance previously found with orally and transdermally administered nicotine. Moreover, results show that such performance was independent of the time of nicotine absorption, which suggests that a relatively low dose of nicotine suffices to activate vigilance processing. Regarding motor performance, no convincing effect of nicotine was observed on reaction time. ((c) 1999 APA/PsycINFO, all rights reserved) [less ▲]

1. An experiment was conducted using three non-lactating cows completely maintained by infusions of volatile fatty acids into the rumen, and casein into the abomasum. Plasma insulin responses to propionic acid, glucose or casein were recorded. Further information was obtained using protein-free infusions. 2. When part of the propionic acid was infused into the rumen in a twice-daily 3 h dose and the remainder infused continuously with acetic and butyric acids and casein, there were large increases in the concentrations of propionic acid and insulin in the jugular blood. When glucose, corresponding in energy to that supplied by the intermittent propionic acid infusions was similarly infused, the plasma levels of glucose and insulin were increased. Glucose appeared to stimulate a greater increase in insulin than did propionic acid. Casein infused into the abomasum in intermittent doses produced a rise in plasma insulin, but smaller than that observed with propionic acid or with glucose. 3. The protein-free infusion was characterized by a lower concentration of insulin in the blood plasma, a reduction in plasma urea and free amino nitrogen and unchanged plasma glucose. [less ▲]
