Quantitative ecology is the application of advanced mathematical and statistics 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.

In CAD CAM, quantitative invisibility QI is the number of solid bodies that obscure a point in space as projected onto a plane. Often, CAD engineers project a model into a plane a 2D drawing , they wish to denote edges that are visible with a solid line and those that are hidden with dashed or dimmed lines. Tracking the number of obscuring bodies gave rise to an algorithm that propagates the quantitative invisibility throughout the model. This technique uses edge coherence to speed calculations in the algorithm. However, QI really only works well when bodies are larger solids, non interpenetrating, and not transparent. A technique like this falls apart when applied to soft organic tissue as found in the human body, because there is not always a clear delineation of structures. Also, when images become too cluttered and intertwined, the contribution of this algorithm is marginal. Arthur Appel of the graphics group at IBM Watson Research coined the term quantitative invisibility and used in several of his papers.

For example, this approach can be used to compare samples from healthy and diseased patients. The methods for protein identification are identical to those used in general i.e. qualitative proteomics , but include quantification as an additional dimension. Mass spectrometry based proteomics Due to differences in ionization efficiency and or detectability the intensity of a peak in a mass spectrum is not a good indicator of the amount of the analyte. However, differences in peak intensity of the same analyte accurately reflect differences in its abundance. Therefore, in mass spectrometry based proteomics relative quantification is used to compare protein abundance between samples. This can be achieved by labeling one sample with stable isotope s alone or incorporated into protein crosslinkers like BisSulfosuccinimidyl suberate D4 BS3 , which leads to a mass shift in the mass spectrum. Differentially labeled samples are combined and analyzed together. The differences in the peak intensities of the isotope pairs accurately reflect difference in the abundance ... refbegin refend See also Protein mass spectrometry Quantitative proteomics bioinformatics stub ... more details

Image Quantitative parasitology 1.JPG thumb 275 px Intensity histograms are helpful to get a first impression about the differences of infection between 2 or more samples. Horizontal axis infection classes, vertical axis the number of host individuals belonging to each class. Counting parasites Quantifying parasites in a sample of hosts or comparing measures of infection across two or more samples can be challenging. The parasitic infection of a sample of hosts inherently exhibits a complex pattern that cannot be adequately quantified by a single statistical measure. As the use of two or more separate indices is advisable, only two or more separate statistical tests can reliably compare infections different samples of hosts. A few of the available statistical measures have markedly different biological interpretations, while others have more or less overlapping interpretations or no interpretations at all. Therefore, one should apply measures that have clear and separate biological interpretations thus do not predict each other. Parasite individuals typically exhibit an skewness aggregated right skewed distribution among host individuals most hosts harbour few if any parasites and a few hosts harbour many of them. This quantitative feature of parasitism renders many of traditional statistical methods obsolete and requires the use of advanced computer intensive statistical methods.
