1. Landscape and soil regionalization in southern Brazilian Amazon and contiguous areas: methodology and relevance for ecological studies
Soils of a large tropical area with differentiated landscapes cannot be treated uniformly for ecological applications. We intend to develop a framework based on physiography that can be used in regional applications. The study region occupies more than 1.1 million km² and is located at the junction of the savanna region of Central Brazil and the Amazon fore

2. Delimitacao do pantanal brasileiro e suas sub-regioes.
Objetiva-se delimitar e quantificar a planicie do Pantanal no Brasil, na escala de 1:250.000, sua sub-regioes e a participacao estadual e municipal nessa regiao. Os criterios adotados na delimitacao foram aspectos relacionados a inundacao, relevo, solo e vegetacao. Os materiais utilizados foram os estudos anteriores relacionados a delimitacao fisiografica do

3. SUBSÍDIOS PARA O PLANEJAMENTO DA PRODUÇÃO DE Pinus elliottii Engelm. NA SERRA DO SUDESTE, RIO GRANDE DO SUL / ALLOWANCES FOR PLANNING THE PRODUCTION OF Pinus elliottii Engelm. IN SERRA DO SUDESTE, RIO GRANDE DO SUL
In Rio Grande do Sul, the Serra do Sudeste has been the target of large forest investments due to government programs for sectorial regional development in the three levels of the administration. One of the species with the largest planted area in the region is the Pinus elliottii Engelm. Two large neighboring counties with typical physiography areas of Serr

4. Environmental representativeness and forest fragmentation in areas dominated by eucalyptus plantations: a proposal for the spatial arrangement of forest fragments / Representatividade ambiental e fragmentação florestal em áreas dominadas por plantios homogêneos: uma proposta para o arranjo espacial de fragmentos florestais
This work presents a landscape study in areas dominated by eucalyptus plantations and native forest. The objectives were to evaluate the spatial configuration and the physiographic and pedologic heterogeneity of native forest fragments, aiming to establish scenarios of arrangement of these fragments that maximize the environmental representativeness of the l

6. Feições fisiográficas submarinas da plataforma continental do Rio Grande do Norte visíveis por imagens de satélite / Underwater physiography of the continental shelf of Rio Grande do Norte visible through satellite imagery
This work introduces visible TM-Landsat imagery as an effective tool for the investigation of underwater physiography on a regional scale, down to 35 m depth, with a resolution of 30 m, on highly reflective seabed on continental shelves with highly transparent waters. The choice of the State of Rio Grande do Norte, Brazil, as the main survey area was dictate

9. K-Ar ages of Pleistocene lava dams in the Grand Canyon in Arizona
At least 13 times during the Pleistocene Epoch lava flowed into the inner gorge of the Grand Canyon and formed lava dams, as high as 600 m, that temporarily blocked the flow of the Colorado River. K-Ar ages on these lava dams indicate that the seven youngest formed within a short period of time between about 0.6 and 0.4 mega-annum (Ma). The physiography of t
