Over 60% of children diagnosed with selective mutism are also diagnosed with Autism Spectrum Disorder. Previous research established that behavioral interventions are effective at increasing speech in children with both diagnoses. However, few studies conducted assessments to determine environmental variables that inhibit speech, and such assessments are necessary for the development of effective and efficient treatments. This case study describes an assessment that evaluated the function(s) of selective mutism. The results confirmed that the participant did not talk to avoid social interaction and that mutism occurred primarily in the presence of multiple, unfamiliar people. Our first treatment focused on increasing tolerance for social interaction, demonstrated by an increase in speech production in the presence of unfamiliar people. Our second treatment focused on increasing qualitative aspects of the participant’s speech (i.e., both responses and initiations). Finally, we taught the participant’s parents to implement the treatment in naturalistic settings, and the participant demonstrated generalization of treatment effects across people and settings. Implications for clinical practice and future research are discussed.

O objetivo do presente trabalho é avaliar as características físico-químicas e microbiológicas dos reservatórios da região do semiárido brasileiro, receptores de água do Projeto de Integração do rio São Francisco, identificando a influência de variáveis ambientais na comunidade fitoplanctônica. Foram estudados os reservatórios de Itaparica, Poço da Cruz, Boqueirão, Armando Ribeiro Gonçalves e Castanhão. Para alcançar o objetivo proposto, foram feitas análises estatísticas multivariadas com auxílio dos programas Primer e SPSS. Verificou-se que os reservatórios se diferenciam em dois grupos (Eixo Leste e Eixo Norte), observando-se a existência de uma variação temporal. As variáveis ambientais explicaram 78% da variação do fitoplâncton. Destes 22% são explicados por variáveis tipológicas (naturais) e 56% são explicados por variáveis de pressão (efeito antropogênico). Espera-se que a transferência de água possa contribuir para melhoria da qualidade da água, sendo fundamental a implementação de medidas que promovam uma gestão integrada e sustentável das respectivas bacias hidrográficas. Palavras-chave: variáveis ambientais, fitoplâncton, reservatórios, semiárido The Influence of Environmental Variables on Phytoplankton Community of the Receptors Reservoirs by the São Francisco River Integration Project ABSTRACT This study aims to evaluate the physico-chemical and microbiological characteristics of brazilian northeast reservoirs, from the São Francisco river Integration Project, to identify the influence of environmental variables on the phytoplankton community. There were studied the reservoirs of Itaparica, Poço da Cruz, Boqueirão, Armando Ribeiro Gonçalves and Castanhão. To achieve the proposed aim, multivariate statistical analyses were performed with the Primer and SPSS programs. It was observed that the reservoirs are distinguish in two groups (East and North Axis), observing the existence of a temporal variation. It was verified that the environmental variables explained 78% of the phytoplankton variation. Of these, 22% are explained by typological variables and 56% are explained by pressure variable. It is expected that the transfer of water may improve water quality (especially in reservoirs of the East Axis). It is essential to implement actions to promote an integrated and sustainable management of their watersheds. Keywords: environmental variables, phytoplankton, reservoirs, semiarid
