Quantitative ecology is the application of advanced mathematical and statistical tools to any number of problems in the field of ecology. It is a small but growing subfield in ecology, reflecting the demand among practicing ecologists to interpret ever larger and more complex data sets using quantitative reasoning. Quantitative ecologists might apply some combination of deterministic or stochastic mathematical models to theoretical questions or they might use sophisticated methods in applied statistics for experimental design and hypothesis testing. Typical problems in quantitative ecology include estimating the dynamics and status of wild populations, modeling the impacts of anthropogenic or climatic change on ecological communities, and predicting the spread of invasive species or diseas

- L'ecologia quantitativa è una branca della più ampia disciplina dell'ecologia, che studia le relazioni esistenti tra organismi e ambiente all'interno di tre livelli di gerarchia biologica: individuo, popolazioni e comunità. L’ecologia, quindi, soprattutto quella quantitativa, si interessa alle interazioni tra esseri viventi e ambiente per poter prevedere reazioni e cambiamenti degli ecosistemi.

- Quantitative ecology is the application of advanced mathematical and statistical tools to any number of problems in the field of ecology. It is a small but growing subfield in ecology, reflecting the demand among practicing ecologists to interpret ever larger and more complex data sets using quantitative reasoning. Quantitative ecologists might apply some combination of deterministic or stochastic mathematical models to theoretical questions or they might use sophisticated methods in applied statistics for experimental design and hypothesis testing. Typical problems in quantitative ecology include estimating the dynamics and status of wild populations, modeling the impacts of anthropogenic or climatic change on ecological communities, and predicting the spread of invasive species or disease outbreaks. Quantitative ecology, which mainly focuses on statistical and computational methods for addressing applied problems, is distinct from theoretical ecology which tends to explore focus on understanding the dynamics of simple mechanistic models and their implications for a general set of biological systems using mathematical arguments.

- L'ecologia quantitativa è una branca della più ampia disciplina dell'ecologia, che studia le relazioni esistenti tra organismi e ambiente all'interno di tre livelli di gerarchia biologica: individuo, popolazioni e comunità. La ricerca in ecologia, inizialmente di carattere descrittivo, intorno al 1930 ha assunto progressivamente un indirizzo sempre più funzionale, con lo sviluppo, appunto, dell'ecologia quantitativa, una disciplina che utilizza metodi di campionamento e di analisi fisiche e chimiche, analisi di sistemi e modelli matematici di simulazione e stabilizzazione di processi ambientali. L’ecologia, quindi, soprattutto quella quantitativa, si interessa alle interazioni tra esseri viventi e ambiente per poter prevedere reazioni e cambiamenti degli ecosistemi. Tutto ciò avviene in tre modalità:
* Raccolta di dati sulle specie presenti in un dato contesto, sul numero di individui delle diverse specie e sui rapporti che intercorrono tra esse (ad esempio preda-predatore).
* Ricostruzione in laboratorio degli ambienti oggetto di studio.
* Creazione di modelli matematici che siano in grado di descrivere le interazioni all’interno di un ecosistema, in un bioma o in una biosfera. (it)
