Termite soil preferences and particle selections: strategies related to ecological requirements
Insectes Sociaux, 2002At 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 ...

A novel ecological particle swarm optimization algorithm and its population dynamics analysis
Applied Mathematics and Computation, 2008This 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, 2018Suspended 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 ...

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.

Multi-Reservoir Ecological Operation Using Multi-Objective Particle Swarm Optimization
Applied Mechanics and Materials, 2014Traditional reservoir operation ignores ecological demands of rivers. This would probably lead to degradation of river ecosystem. In order to alleviate the influence of reservoirs on river ecosystem, multi-objective reservoir ecological operation was proposed from perspective of maintaining the river ecosystem health. Multi-objective mathematical model

Sedimentary particle sizes and the ecological grain of food resources for meiobenthic copepods
Estuarine, Coastal and Shelf Science, 1986Abstract On average, sand particles larger than 300 μm have at least one large smooth facet on their surfaces on which the epifloral food of meiobenthic copepods is distributed as a coarse-grained ecological resource. Sand particles smaller than 300 μm have irregular surfaces composed of pits, faults and encrustations in which food organisms are ...
