Heterogeneous genetic structure in a natural population of Raulí (Nothofagus nervosa)
(Pontificia Universidad Catolica de Chile, Facultad de Agronomia e Ingenieria Forestal, 2011)
Heterozygote deficiencies in natural populations of outbreeding tree species are common and thought to be due mainly to biparental inbreeding. Inbreeding is believed to be caused by family structure within populations, a ...
Query rewriting for semantic query optimization in spatial databases
(2019)
Query processing is an important challenge for spatial databases due to the use of complex data types that represent spatial attributes. In particular, due to the cost of spatial joins, several optimization algorithms based ...
Diversity and spatial structure of the landscapes of the Khemchik river basin
(Universidad del Zulia, 2019)
Broad-scale spatial patterns of canopy cover and pond morphology affect the structure of a Neotropical amphibian metacommunity
(Springer, 2014-08-01)
Spatial and environmental processes influence species composition at distinct scales. Previous studies suggested that the distribution of larval anurans at the landscape-scale is influenced by environmental gradients related ...
Spatial Variability of Soil Organic Matter and Cation Exchange Capacity in an Oxisol under Different Land Uses
(2016-12-30)
Soil properties may exhibit large spatial variability. Frequently this variability is auto-correlated at a certain scale. In addition to soil-forming factors, soil management, land cover, and agricultural system may affect ...
Modeling and measuring the spatial relation "along": Regions, contours and fuzzy sets
(ELSEVIER SCI LTDOXFORD, 2012)
The analysis of spatial relations among objects in an image is an important vision problem that involves both shape analysis and structural pattern recognition. In this paper, we propose a new approach to characterize the ...
Impact of the spatial structure on the returns of the stock indexesImpacto de la estructura espacial en los retornos de los índices accionarios
(Centro de Investigaciones Comerciales e Iniciativas Académicas, 2007)
Long-established rules and emergent challenges: spatial planning and wildfires in Chile
(2023)
It is generally expected that spatial planning integrates wildfire risk reduction considerations in areas affected by this hazard. However, many spatial planning systems are challenged to adequately deal with this risk. ...
Temporal changes in mesoscale aggregations and spatial distribution scenarios of the Peruvian anchovy (Engraulis ringens)
(Elsevier, 2019)
The Peruvian anchovy (Engraulis ringens) is the most important small pelagic of the Humboldt Current System (HCS), supporting the largest mono-specific fishery in the world. The spatial behavior of this species tends to ...
