In the twentieth century, red fox (Vulpes vulpes) expanded into the Canadian Arctic, where it competes with arctic fox (Vulpes lagopus) for food and shelter. Red fox dominates in physical interactions with the smaller arctic fox, but little is known about competition between them on the tundra. On Hershel Island, north Yukon, where these foxes are(More)
Sulpiride is a new antipsychotic agent chemically different from recognized psychotropic compounds. The animal profile and the rapid urinary excretion without metabolism also distinguishes this drug from other neuroleptics. Previous studies have indicated therapeutic efficacy and few side effects. Sulpiride was evaluated in 10 hospitalized, chronic(More)
Findings in this study support earlier investigations in attesting to the antipsychotic efficacy and relatively low toxicity of pipotiazine palmitate. Results with all efficacy measures utilized were consistent in indicating a high level of efficacy for this investigational compound. Pipotiazine palmitate apparently has an average duration of action that(More)
During the last century, the red fox (Vulpes vulpes) has expanded its distribution into the Arctic, where it competes with the arctic fox (Vulpes lagopus), an ecologically similar tundra predator. The red fox expansion correlates with climate warming, and the ultimate determinant of the outcome of the competition between the two species is hypothesized to(More)
