Hunt's Mesa adjoins the southern part of Monument Valley about six miles south of the Arizona-Utah state line. The area has not been surveyed, but the location, as determined from uncontrolled areal mosaics, is between latitudes 36° 53.5' and 36° 54' N., and longitudes 110° 3.5' and 110° 4.25' W.

Coarse-resolution thematic maps derived from remotely sensed data and implemented in GIS play an important role in coastal and marine conservation, research and management. Here, we describe an approach for fine-resolution mapping of land-cover types using aerial photography and ancillary GIs and ground data in a large (100 x 35 km) subtropical estuarine system (Moreton Bay, Queensland, Australia). We have developed and implemented a classification scheme representing 24 coastal (subtidal, intertidal. mangrove, supratidal and terrestrial) cover types relevant to the ecology of estuarine animals, nekton and shorebirds. The accuracy of classifications of the intertidal and subtidal cover types, as indicated by the agreement between the mapped (predicted) and reference (ground) data, was 77-88%, depending on the zone and level of generalization required. The variability and spatial distribution of habitat mosaics (landscape types) across the mapped environment were assessed using K-means clustering and validated with Classification and Regression Tree models. Seven broad landscape types could be distinguished and ways of incorporating the information on landscape composition into site-specific conservation and field research are discussed. This research illustrates the importance and potential applications of fine-resolution mapping for conservation and management of estuarine habitats and their terrestrial and aquatic wildlife.

Increasingly, large areas of native tropical forests are being transformed into a mosaic of human dominated land uses with scattered mature remnants and secondary forests. In general, at the end of the land clearing process, the landscape will have two forest components: a stable component of surviving mature forests, and a dynamic component of secondary forests of different ages. As the proportion of mature forests continues to decline, secondary forests play an increasing role in the conservation and restoration of biodiversity. This paper aims to predict and explain spatial and temporal patterns in the age of remnant mature and secondary forests in lowland Colombian landscapes. We analyse the age distributions of forest fragments, using detailed temporal land cover data derived from aerial photographs. Ordinal logistic regression analysis was applied to model the spatial dynamics of mature and secondary forest patches. In particular, the effect of soil fertility, accessibility and auto-correlated neighbourhood terms on forest age and time of isolation of remnant patches was assessed. In heavily transformed landscapes, forests account for approximately 8% of the total landscape area, of which three quarters are comprised of secondary forests. Secondary forest growth adjacent to mature forest patches increases mean patch size and core area, and therefore plays an important ecological role in maintaining landscape structure. The regression models show that forest age is positively associated with the amount of neighbouring forest, and negatively associated with the amount of neighbouring secondary vegetation, so the older the forest is the less secondary vegetation there is adjacent to it. Accessibility and soil fertility also have a negative but variable influence on the age of forest remnants. The probability of future clearing if current conditions hold is higher for regenerated than mature forests. The challenge of biodiversity conservation and restoration in dynamic and spatially heterogeneous landscape mosaics composed of mature and secondary forests is discussed. (c) 2004 Elsevier B.V.

Australian lungfish Neoceratodus forsteri may be the closest living relative to the first tetrapods and yet little is known about their retinal ganglion cells. This study reveals that lungfish possess a heterogeneous population of ganglion cells distributed in a horizontal streak across the retinal meridian, which is formed early in development and maintained through to adult stages. The number and complement of both ganglion cells and a population of putative amacrine cells within the ganglion cell layer are examined using retrograde labelling from the optic nerve and transmission electron-microscopic analysis of axons within the optic nerve. At least four types of retinal ganglion cells are present and lie predominantly within a thin ganglion cell layer, although two subpopulations are identified, one within the inner plexiform and the other within the inner nuclear layer. A subpopulation of retinal ganglion cells comprising up to 7% or the total population are significantly larger (> 400 mu m(2)) and are characterized as giant or alpha-like cells. Up to 44% of cells within the retinal ganglion cell layer represent a population of presumed amacrine cells. The optic nerve is heavily fasciculated and the proportion of myelinated axons increases with body length from 17% in subadults to 74% in adults. Spatial resolving power, based on ganglion cell spacing, is low (1.6-1.9 cycles deg(-1), n = 2) and does not significantly increase with growth. This represents the first detailed study of retinal ganglion cells in sarcopterygian fish, and reveals that, despite variation amongst animal groups, trends in ganglion cell density distribution and characteristics of cell types were defined early in vertebrate evolution.

O campo religioso brasileiro apresenta, em sua configuração atual, uma formatação identitária extremamente diversa daquela observada em décadas anteriores. A partir dessa consideração, emerge uma problemática significativa - como compreender essas mudanças? Por que um cenário, antes extremamente resistente a transformações, agora se abre aos ventos modernizantes permitindo a recomposição de suas formas religiosas? Ora, a construção de novas identidades e a reordenação dos padrões religiosos podem ser compreendidas a partir do fenômeno do trânsito religioso, considerando ser possível iden-tificar na movimentação dos sujeitos uma dinâmica que estabelece alterações, tanto no caráter institucional e litúrgico dos grupos, bem como na vivência prática dos / das fiéis, promovendo inéditos e provisórios sistemas simbólicos. Diante da multiplicidade de oferta, os sujeitos apresentam uma mobilidade incessante num processo de ressignificação permanente, formando efêmeros mosaicos nos quais se distinguem múltiplas cores, formas, espaços, demandas, motivações, comportamentos, interesses, habitus, tradições, símbolos, disposições, estratégias, gostos e combinações. A partir dos postulados das Ciências da Religião, essa pesquisa propõe-se a analisar esse evento tendo como universo de observação a Igreja Evangélica Assembleia de Deus, Ministério São Bernardo do Campo. Objetiva demonstrar, mediante a interpretação do con-junto de dados obtidos em pesquisa de campo correlacionado com os fundamentos teóricos, a recomposição das formas religiosas institucionais e as novas identidades desenvolvidas pelos sujeitos a partir da mobilidade; estabelecer uma conexão entre os elementos indicadores da pesquisa e o fenômeno caracterizado para identificar quais são as motivações de gênero, classe, geracional e de etnia para o trânsito de homens e mulheres que circulam das mais diversas alternativas para esse grupo religioso e, considerando esse referencial, compreender como a instituição religiosa absorve esse fluxo de pessoas.
