Use of Coarse-resolution models of species' distributions to guide local conservation inferences

Distribution models are used increasingly for species conservation assessments over extensive areas, but the spatial resolution of the modeled data and, consequently, of the predictions generated directly from these models are usually too coarse for local conservation applications. Comprehensive distribution data at finer spatial resolution, however, require a level of sampling that is impractical for most species and regions. Models can be downscaled to predict distribution at finer resolutions, but this increases uncertainty because the predictive ability of models is not necessarily consistent beyond their original scale. We analyzed the performance of downscaled, previously published models of environmental favorability (a generalized linear modeling technique) for a restricted endemic insectivore, the Iberian desman (Galemys pyrenaicus), and a more widespread carnivore, the Eurasian otter ( Lutra lutra), in the Iberian Peninsula. The models, built from presence–absence data at 10 × 10 km resolution, were extrapolated to a resolution 100 times finer (1 × 1 km). We compared downscaled predictions of environmental quality for the two species with published data on local observations and on important conservation sites proposed by experts. Predictions were significantly related to observed presence or absence of species and to expert selection of sampling sites and important conservation sites. Our results suggest the potential usefulness of downscaled projections of environmental quality as a proxy for expensive and time-consuming field studies when the field studies are not feasible. This method may be valid for other similar species if coarse-resolution distribution data are available to define high-quality areas at a scale that is practical for the application of concrete conservation measures

As percepções de alunos, professores e encarregados de educação sobre a disciplina de educação musical: Um estudo de caso no âmbito do 2º ciclo do ensino básico

Este estudo teve como grande finalidade conhecer as percepções de alunos do 2° Ciclo do Ensino Básico de uma escola da periferia de Lisboa e dos respectivos professores e encarregados de educação, relativamente à disciplina de Educação Musical. No estudo foi utilizado um desenho metodológico de cariz naturalista, com aproximação ao estudo de caso, em que a técnica de recolha de dados de suporte foi o inquérito por questionário, aplicado aos três elementos da comunidade educativa antes referidos. Os principais objectivos do estudo foram, entre outros, os seguintes: #) Conhecer a importância que é dada à Educação Musical, enquanto disciplina integrante do currículo escolar, por alunos, professores e encarregados de educação; #) Contribuir para uma tomada de consciência, por parte da comunidade educativa em geral, sobre a importância da Educação Musical na formação integral do cidadão. A análise dos resultados obtidos permitiu chegar a diversas inferências e conclusões, destacando-se, entre outras, as seguintes: - Em relação aos alunos, a Educação Musical foi por eles considerada uma disciplina razoavelmente importante para a sua formação face à qual afirmaram nutrir algum interesse, sobretudo quando nela são promovidas actividades práticas; - No que diz respeito aos professores, estes consideraram, na sua maioria, que a disciplina, apesar das suas potencialidades formativas, acaba por não ser aproveitada na sua plenitude; - Os encarregados de educação tenderam a considerá-la uma disciplina importante, parecendo estar informados sobre as actividades e as funções a ela associadas. A música pareceu, além disso, fazer parte da vida da maior parte dos inquiridos dos três grupos participantes no estudo, tendo os mesmos indicado que ouviam música todos os dias e que já haviam assistido a, pelo menos, um concerto ao vivo. ABSTRACT; The aim of this study was to acknowledge the perceptions of students of the fifth and sixth grades of a Basic school in Lisbon periphery, their parents and teachers, about the subject of Musical Education. ln that purpose, we are in front of a naturalist investigation, approaching the case study, were the support instrument of data collecting was the questionnaire, applied to the three members of the educative community we have already referred to. This study had, as main goals, the following, among others: #) To know the importance that is given to Musical Education, as a subject which is part of the school curriculum, by students, parents and teachers; #) To contribute for the acknowledgement, by the general educative community, of the importance of Musical Education, for the growth and formation of the individuals. The analisys of the results allowed us to reach, among others, several conclusions and inferences: - Concerning the students, musical education was considered a subject of reasonable importance for their formation, and by which they showed some interest, especially when teachers promote practical activities; - The majority of the teachers considered that the subject was very important for the formation of the individual. However, and in spite of its formative potentialities, musical education is not applied and used as much as it should be; - Parents seem to consider it an important subject and also seem to be well informed about the activities and functions associated to it; Music seemed to be part of the lives of all the inquiries, who revealed listening to music every day and, in the majority of cases, have already been to a live concert.
