Fine spatial structure of genetically distinct picocyanobacterial populations across environmental gradients in the Costa Rica Dome
Fine spatial structure genetically distinct picocyanobacterial populations across environmental gradients in the Costa Rica Dome
2014/4/2
We investigated the spatial variability of picocyanobacterial community structure across the Costa Rica Dome(CRD), an offshore upwelling system characterized by high seasonal abundance of Synechococcu...
CHANGES IN THE URBAN SPATIAL STRUCTURE OF THE GREATER CAIRO METROPOLITAN AREA, EGYPT
Greater Cairo pixel-based and object-based classifications land use/land cover (LU/LC) change detection analysis
2014/5/9
Since the 1980s, rapid population growth and urbanization have become issues in big cities like Greater Cairo (GC). As a consequence of explosive growth, the living conditions of Cairo Metropolis dete...
Effects of spatial structure and diffusion on the performances of the chemostat
spatial structure the chemostat
2010/11/22
Given hydric capacity and nutrient flow of a chemostat-like system, we analyse the influence of a spatial structure on the output concentrations at steady-state. Three configurations are compared: pe...
Minkowski Tensors of Anisotropic Spatial Structure
Minkowski Tensors Anisotropic Spatial Structure
2010/12/15
We describe a novel approach to morphology and anisotropy analysis of complex spatial structure using tensorvalued Minkowski functionals, or Minkowski tensors.
On the Characteristics of Housing Spatial Structure and Location Selection of Residential Communities: A Case Study of Wuhan City
Residential communities Housing spatial structure Residential location selection
2009/12/3
With the deepening of the housing system reform in China, the residential spatial structure has graduallyassumed a complex shape along with its tremendous changes in Wuhan city. It is very crucial and...
Geostatistical investigation into the temporal evolution of spatial structure in a shallow water table
spatial structure shallow water table
2009/5/13
Shallow water tables near-streams often lead to saturated, overland flow generating areas in catchments in humid climates. While these saturated areas are assumed to be principal biogeochemical hot-sp...
Assessment of spatial structure of groundwater quality variables based on the entropy theory
transinformation correlation spatial structure
2009/3/12
Fundamental to the spatial sampling design of a groundwater quality monitoring network is the spatial structure of groundwater quality variables. The entropy theory presents an alternative approach to...
The Mesoscale Spatial Structure and Evolution of Dynamical and Scalar Properties Observed in the Northwestern Atlantic Ocean during the POLYMODE Local Dynamics Experiment
Local Dynamics Experiment Mesoscale Spatial Structure Scalar Properties
2009/1/10
Dynamical properties examined in this paper are the dynamic height and the pressure on an isopycnal. Scalars are the salinity and the oxygen concentration on an isopycnal. The sea surface temperature ...
Spatial structure of the 8200 cal yr BP event in northern Europe
northern Europe 8200 cal yr BP event
2008/11/3
A synthesis of well-dated high-resolution pollen records suggests a spatial structure in the 8200 cal yr BP event in northern Europe. The temperate, thermophilous tree taxa, especially Corylus, Ulmus,...
Temporal and Spatial Structure of the Equatorial Deep Jets in the Pacific Ocean
Temporal Spatial Structure Equatorial Deep Jets Pacific Ocean
2008/6/25
The spatial and temporal structure of the equatorial deep jets (EDJs) in the Pacific Ocean is investigated using CTD station data taken on the equator from 1979 through 2001. The EDJs are revealed in ...
Small-scale spatial structure in plankton distributions
Small-scale spatial structure plankton distributions
2010/1/14
The observed filamental nature of plankton populations suggests that stirring plays an important role in determining their spatial structure. If diffusive mixing is neglected, the various interacting ...
Spatial structure of the dominant basin-scale internal waves in Lake Kinneret
dominant basin-scale internal waves Lake Kinneret
2014/4/23
Field data and numerical simulations were used to investigate the effects of basin shape, continuous stratification,
and rotation on the three-dimensional structure of the dominant natural basi...
