Implications of network particle tracking (NPT) for ecological model interpretation

Ecological Modelling, 2009
Abstract Network particle tracking (NPT), building on the foundation of network environ analysis (NEA), is a new development in the definition of coherence relations within and between connected systems. This paper evaluates three ecosystem models in a comparison of throughflow- and storage-based NEA and NPT. Compartments in models with high indirect

Purification Effect on Particle Size of Matrix in Ecological Filter Bed

Applied Mechanics and Materials, 2012
In order to study the purification effect on the particle size of matrix in ecological filter bed, four ecological filter bed units with different particle sizes (0~2mm, 2~15mm, 15~30mm, 30~50mm) are designed to purify the polluted river water. Results show that the particle size of matrix has considerable influence on the polluted river water quality ...

Termite soil preferences and particle selections: strategies related to ecological requirements

Insectes Sociaux, 2002
At the Lamto Savanna Ecological Station (Cote d'Ivoire), Odontotermes nr. pauperans (Termitidae, Macrotermitinae) was observed to build mounds enriched with fine particles. Using laboratory experiments we studied the selection of building materials by worker termites offered soil from two contrasting horizons: superficial soil (15-20 cm) and a deeper ...

Plastic particles in soil: state of the knowledge on sources, occurrence and distribution, analytical methods and ecological impacts

Environmental Science: Processes & Impacts, 2021
Increased production and use of plastics has resulted in growth in the amount of plastic debris accumulating in the environment, potentially fragmenting into smaller pieces.

A novel ecological particle swarm optimization algorithm and its population dynamics analysis

Applied Mathematics and Computation, 2008
This paper presents a novel particle swarm optimization algorithm from the angle of ecological population evolution, called the ecological particle swarm optimization, or EPSO. Initially, ecological population competition model (EPCM) is presented. From the basis of the EPCM, the EPSO algorithm and its general framework are proposed; in which particle ...

Individual particle measurements to monitor ecological processes in the Indian River Lagoon, FL

Ocean Sensing and Monitoring X, 2018
Suspended particles are important components of coastal marine ecosystems that are often the target of environmental sensing efforts (e.g. harmful algae blooms, suspended sediments). Automated measurements of individual particles provide advantages over traditional manual methods of particle analysis and sensors that measure bulk water properties ...

Construction and application of particle swarm optimization algorithm for ecological spatial data mining

SPIE Proceedings, 2009
The research of the regional ecological environment becomes more important to regional Sustainable Development in order to achieve the harmonious relationship between the person and the nature. The advent of spatial information technologies, such as GIS, GPS and RS, have great enhanced our capabilities to collect and capture spatial data.
