Esta pesquisa verifica a opinião da criança por meio do desenho sobre o Lar de Longa Permanência para Idosos, antes e depois de contato lúdico com idosos institucionalizados. Para melhor caracterizar a população idosa, traça seu perfil neuropsicológico. Desenvolve-se junto a 21 idosos institucionalizados e 61 crianças com idades entre 7 e 12 anos, do Ensino Fundamental público. Inicia-se por verificar a opinião destas crianças sobre Asilo, por meio de desenho. Em seguida, realiza intervenção lúdica com crianças e idosos, de 10 encontros com brincadeiras simbólicas e jogos de regras. A seguir, reavalia a opinião das crianças e faz avaliação neuropsicológica dos idosos, por meio de Mini-Exame do Estado Mental, da Escala de Depressão Geriátrica, do Short-Form Health Survey (SF-36) e do Índice de Katz. Para verificar a opinião das crianças expressa por meio do desenho, utiliza de um título em aberto Asilo é..., a ser completado. Eles são analisados com subsídios do teste projetivo House-Tree-Person (HTP). Os resultados demonstram que houve, de uma aplicação para outra, alteração na opinião de 67% das crianças, que manifestaram opinião mais positiva relativa a perceber os idosos mais interativos e o Asilo mais humanizado, por meio de desenhos mais coloridas, de casas com portas e janelas, de pessoas sorrindo e em movimento e de mensagens afetuosas. Como aspectos negativos, encontram-se maior número de grades e de pessoas desenhadas sem face, o que pode representar a percepção da criança da dificuldade de contato do idoso com o mundo externo. Na análise estatística, encontrou-se média geral de 0,34 e desvio padrão de 0,16, no primeiro desenho e, no segundo, média de 0,42 e desvio padrão de 0,19, com médias obtidas numa escala de 0 a 1, em que se considera positivo o valor próximo a 1. Na avaliação neuropsicológica dos idosos, no MEEM, 50% demonstram preservação cognitiva. Os demais instrumentos indicam que a maior parte deles não apresenta sintomas depressivos, emite opinião positiva com relação à própria saúde, participa das atividades lúdicas e é dependente. Este estudo ressalta contudo que as características da instituição pesquisada, juntamente com a realização de atividades lúdicas, podem ter favorecido a opinião das crianças após seu contato com o Asilo. O estudo indica a necessidade de novas pesquisas sobre interação criança-idoso institucionalizado

The pine rocklands of South Florida are characterized by an herbaceous flora with many narrowly endemic taxa, a diverse shrub layer containing several palms and numerous tropical hardwoods, and an overstory of south Florida slash pine (Pinus elliottii var. densa). Fire has been considered as an important environmental factor for these ecosystems, since in the absence of fire these pine forests are replaced by dense hardwood communities, resulting in loss of the characteristic pineland herb flora. Hence, in the Florida Keys pine forests, prescribed fire has been used since the creation of the National Key Deer Refuge. However, such prescribed burns were conducted in the Refuge mainly for fuel reduction, without much consideration of ecological factors. The USGS and Florida International University conducted a research study for four years, from 1998 to 2001, the objective of which was to document the response of pine rockland vegetation to a range of fire management options and to provide Fish and Wildlife Service and other land managers with information useful in deciding when and where to burn to perpetuate these unique pine forests. This study is described in detail in Snyder et al. (2005).

The Amazon savannas occur as isolated patches throughout extensive areas of forest in the states of Amapá, Amazonas, Pará, and Roraima. There is a considerable variation in the composition of anuran assemblages in the localities and phytophysiognomies of Amazon savannas and given the absence of studies on reproductive behavior, a systematic and geographically wide sampling has been carried out in the Amapá savanna, located in the Eastern Amazon. The study was conducted in a savanna area in the state of Amapá to examine the composition, ecology, and reproductive behavior of anuran amphibians. We carried out 24 field trips in each phytophysiognomy (gramineous-woody savana, gramineous-herbaceous-woody savana, park savana, and arboreal savanna); for analysis of reproductive behavior observations were made during the period January to December 2013, lasting four consecutive days. Samples were collected by active and acoustic search along 20 plots of 100x50 meters. Twenty-one anuran species were recorded, of which four are new records for the state of Amapá: Dendropsophus walfordi, Scinax fuscomarginatus, Pseudopaludicola boliviana e Elachistocleis helianneae. The KruskalWallis ANOVA revealed significant differences between richness and species diversity in the phytophysiognomies (p < 0.05). The Bray-Curtis similarity coefficient divided the phytophysiognomies into three groups: arboreal savana, gramineous-woody savanna and gramineous-herbaceous-woody savanna, and park savanna. According to the non-metric multidimensional scaling, the structure of the anuran community resulted in a separation into three phytophysiognomies, with significant differences in the structure of communities (ANOSIM, R = 0.823; p < 0.001). In the study of community ecology, the results obtained for spatial, temporal, and trophic niche breadth suggest that the assemblage of anurans of the Amapá savanna is not composed of predominantly generalist species. Also, the presence of other specialist anurans may explain the processes of speciation associated with the isolation of habitats, resulting in heterogeneity and spatial discontinuity in the phytophysiognomies with open formations. The null model analysis revealed that the community is structured based on temporal and trophic niche, indicating a significant influence of contemporary ecological factors on the assemblage. The absence of structure based on spatial niche might be explained by the spatial segregation in the distribution and occupation of anurans in the different phytophysiognomies of the Amapá savanna. Regarding the reproductive behavior of anurans, 11 species were classified as having a long breeding season, intrinsically associated with the rainy season and the reproductive mode of most species that lay egg clutches in lentic water bodies. Six reproductive modes were recorded and parental care was observed in Leptodactylus macrosternum and L. podicipinus, whose reproductive mode is characterized by foam nests. Regarding behavioral reproductive strategies, calling males were observed in all species of anurans, satellite males were recorded only for D. walfordi, Hypsiboas multifasciatus, S. nebulosus and S. fuscomarginatus; active search for females was observed for Phyllomedusa hypochondrialis and L. fuscus, and male displacement was recorded only for Rhinella major and R. margaritifera. Of the reproductive behaviors observed, throat and vocal sac display is associated with courtship and territorial behavior exhibited by males. In addition to courtship behavior, visual signals associated with courtship strategies were recorded for the anurans of the Amapá savanna.
