Deutsch: Bereich / Español: Rango / Português: Alcance / Français: Gamme / Italiano: Gamma /
A Range is the difference between the maximum and minimum values of a set of values. When the number of values is small (i.e., eight or less), the range is a relatively sensitive (efficient) measure of variability. As the number of values increases above eight, the efficiency of the range (as an estimator of the variability) decreases rapidly. The range, or difference between two paired values, is of particular importance in air pollution measurement, since in many situations duplicate measurements are performed as part of the quality assurance program.
Deutsch: Toleranzbereich / Español: Rango de tolerancia / Português: Faixa de tolerância / Français: Plage de tolérance / Italiano: Gamma di tolleranza /
Range of tolerance is the range of chemical and physical conditions that must be maintained for populations of a particular species to stay alive and grow, develop, and function normally.A Ranked Set Sampling is a specimen site-selection process wherein expert judgment or an auxiliary measurement method is used, in combination with simple random specimen collection, to determine which locations in the field should be selected.
English: Grid / Español: Cuadrícula / Português: Grade / Français: Grille / Italiano: Griglia
Raster in the environment context refers to a type of data structure used in geographic information systems (GIS) and remote sensing. It consists of a matrix of cells or pixels, each representing a specific geographic area and containing a value that corresponds to an environmental attribute, such as temperature, elevation, vegetation, or land cover. Raster data is fundamental in environmental analysis, as it allows for the representation and analysis of spatial data over large areas in a consistent and measurable way.
Deutsch: Ratte / Español: Rata / Português: Rato / Français: Rat / Italiano: Ratto
Rats in the environment context refer to small to medium-sized rodents that are often found living in close association with human populations. They are known for their remarkable adaptability to various habitats and their ability to survive in harsh conditions. While they play a role in the natural ecosystem, their presence in human environments can have significant environmental and health implications.
Deutsch: Rate / Español: Tasa / Português: Taxa / Français: Taux / Italiano: Tasso
Rate in the environment context refers to a quantitative measure that expresses the occurrence or magnitude of a particular environmental phenomenon within a specified time frame. It is a critical metric used to assess, monitor, and understand the dynamics of environmental processes and their impacts on ecosystems, climate, and human societies.
Deutsch: Auftretensrate / Español: Tasa de ocurrencia / Português: Taxa de ocorrência / Français: Taux d’occurrence / Italiano: Tasso di occorrenza
In the environmental context, rate of occurrence refers to how frequently a particular environmental event, condition, or phenomenon happens within a specific time period or geographical area. It is a statistical measure used to track patterns, detect trends, and assess environmental risks.
