A hierarchical model to estimate the abundance and biomass of salmonids by using removal sampling and biometric data from multiple locations [PDF]
, 2010 We present a Bayesian hierarchical model to estimate the abundance and the biomass of brown trout (Salmo trutta fario) by using removal sampling and biometric data collected at several stream sections.

Using an Automatic Resistivity Profiler Soil Sensor On-The-Go in Precision Viticulture
Sensors, 2013 Spatial information on vineyard soil properties can be useful in precision viticulture. In this paper a combination of high resolution soil spatial information of soil electrical resistivity (ER) and ancillary topographic attributes, such as elevation ...

Sky Variability in the y Band at the LSST Site [PDF]
, 2010 We have measured spatial and temporal variability in the y band sky brightness over the course of four nights above Cerro Tololo near Cerro Pachon, Chile, the planned site for the Large Synoptic Survey Telescope (LSST).

Spatial variability assessment of soil available phosphorus using geostatistical approach
The Indian Journal of Agricultural Sciences, 2020 Soil available phosphorus (P), a major plant nutrient, exhibits a high degree of spatial variability. Spatial variability assessment of P is necessary for its precise management using geostatistics.

Spatial and temporal variability of rainfall and their effects on hydrological response in urban areas – a review [PDF]
Hydrology and Earth System Sciences, 2017 In urban areas, hydrological processes are characterized by high variability in space and time, making them sensitive to small-scale temporal and spatial rainfall variability.

Satisfiability of a Spatial Logic with Tree Variables [PDF]
, 2007 We investigate in this paper the spatial logic TQL for querying semi-structured data, represented as unranked ordered trees over an infinite alphabet. This logic consists of usual Boolean connectives, spatial connectives (derived from the constructors of a tree algebra), tree variables and a fixpoint operator for recursion.

Extracting Additional Information From Biotic Index Samples [PDF]
, 2017 Macroinvertebrates were collected from a small midwestern stream over a 3-year period as part of a non-point source pollution study. Temporal and spatial variability in standard biotic index values (BIs) were computed and compared with variability ...
