Automobile exhaust has become the main source of atmospheric particulate matter with the increase in the number of automobiles. Automobile exhaust particles (AEPs) discharged into the atmosphere can enter the aquatic environment through atmospheric deposition, rain runoff, leaching, drainage water and urban sewage and further affect aquatic organisms ...

Depending on the origin, riverine aggregates (suspended material) harbor a complex mixture of inorganic and organic components. The living organic components are characterized by nucleic acid-containing constituents such as algae, protozoa, fungi, bacteria and virus-like particles.

Particle Size Spectra in Ecology
1984The use of size distributions as descriptors of ecosystems goes back at least to Elton (1927), although quantitative applications have appeared only during the past decade. Elton noted that there was a characteristic difference between terrestrial and aquatic ecosystems; on land the organisms in the lower trophic levels tend to be larger than the ...

Implications of network particle tracking (NPT) for ecological model interpretation
Ecological Modelling, 2009Abstract 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, 2012In 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 ...

Empirical study of particle swarm optimization inspired by Lotka–Volterra model in Ecology
Soft Computing, 2018Particle swarm optimization (PSO) has been proved to be an effective technique in solving complex global optimization problems. Many modified versions of the original PSO algorithm emerged during the last 15 years. Many of those existing methods employ all particles in a single population which adopts the similar monotonic strategy.

Microplastic's triple threat The billions of tons of plastics that we release into the environment for the most part do not biodegrade. But they do degrade, breaking into ever smaller particles that end up in the oceans. Lönnstedt et al.

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 ...
