Qualidade De Solo E Liteira Em Vegetação Pós Mineração E Fragmento Florestal Em Capitão Poço, Pará, Brasil

Abstract: O presente estudo teve como objetivo avaliar alguns atributos químicos e físicos do solo, bem como a serapilheira acumulada acima do solo em duas áreas em diferentes épocas de pousio após a exploração de seixo e areia, em comparação com uma floresta secundária. O estudo foi realizado no município de Capitão Poço, Pará, Brasil. Cada área de estudo possui cerca de 5 ha. As três áreas são compostas por um fragmento florestal (FOR), uma área minerada com pousio de 48 meses (DA48) e uma área minerada em um período … Show more

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.
