What is Canoco for Windows 45?
Canoco for Windows 45 is the next generation of Canoco software, which is one of the most popular tools for constrained and unconstrained ordination in ecological applications. Ordination is a statistical technique that aims to reveal the underlying patterns and gradients in multivariate data sets, such as species composition, environmental variables, or experimental treatments. Ordination can help you answer questions such as:
Which factors are most important in explaining the variation in your data?
How are your samples or sites related to each other in terms of similarity or dissimilarity?
How are your variables correlated or associated with each other?
How can you visualize your data in a meaningful way?
Canoco for Windows 45 allows you to perform various ordination methods, such as:
Principal components analysis (PCA), which is a linear method that maximizes the variance explained by the first few axes.
Redundancy analysis (RDA), which is a linear method that maximizes the variance explained by a set of explanatory variables.
Correspondence analysis (CA), which is a unimodal method that assumes a bell-shaped response curve of species to environmental gradients.
Detrended correspondence analysis (DCA), which is a unimodal method that removes the effect of arching or horseshoe distortion in CA.
Canonical correspondence analysis (CCA), which is a unimodal method that maximizes the variance explained by a set of explanatory variables while accounting for unimodal response curves.
In addition, Canoco for Windows 45 can also perform other methods based on these core techniques, such as:
Canonical variate analysis (CVA), which is a linear method that discriminates between predefined groups of samples.
Principal coordinates analysis (PCoA), which is a linear method that uses a distance matrix instead of raw data.
Canoco for Windows 45 integrates ordination with regression and permutation methodology, so as to allow sound statistical modeling of ecological data. You can test the significance of your ordination results using various permutation tests, such as Monte Carlo tests, partial Monte Carlo tests, or restricted permutation tests. You can also perform forward or backward selection of explanatory variables, or use automatic model building procedures such as BEST or GLM.
Canoco for Windows 45 is not the only software package that can perform ordination methods. There are other similar packages, such as PC-ORD, SYN-TAX, or R. However, Canoco for Windows 45 has some advantages over these packages, such as:
It has a more intuitive and user-friendly interface, with graphical and tabular output options.
It has a more comprehensive and up-to-date set of ordination methods, with more flexibility and options for customization.
It has a more robust and reliable statistical framework, with rigorous permutation tests and model selection procedures.
It has a more active and supportive development team, with regular updates and improvements.
Therefore, if you want to use a state-of-the-art tool for multivariate analysis of ecological data, you should consider Canoco for Windows 45 as your first choice.

How to use Canoco for Windows 45?
Once you have downloaded and installed Canoco for Windows 45, you can start using it to analyze your ecological data. The software has a simple and intuitive interface that consists of three main components:
The Project Explorer, which shows the structure of your project and allows you to manage your data files, ordination results, graphs, tables, and reports.
The Data Editor, which allows you to view and edit your data in a spreadsheet-like format. You can also import data from other sources, such as Excel or text files.
The Output Viewer, which displays your ordination results in graphical or tabular form. You can also customize your graphs, perform statistical tests, or export your output to other formats or applications.
To perform an ordination analysis with Canoco for Windows 45, you need to follow these basic steps:
Create a new project or open an existing one from the Project Explorer.
Add or import your data files (response data and explanatory data) to your project from the Data Editor.
Select an ordination method (PCA, RDA, CA, DCA, CCA, etc.) from the Project Explorer.
Specify the options and parameters for your ordination method from the Output Viewer.
Run the analysis and view your results in graphical or tabular form from the Output Viewer.
Let's see an example of how to perform a canonical correspondence analysis (CCA) with Canoco for Windows 45. CCA is a unimodal ordination method that maximizes the variance explained by a set of explanatory variables while accounting for unimodal response curves of species to environmental gradients. CCA is suitable for data sets that have a strong gradient length and a clear relationship between response and explanatory variables.
For this example, we will use a data set that contains the abundance of 30 plant species in 26 sites along an altitudinal gradient in the Swiss Alps. The data set also contains four explanatory variables: altitude, slope, aspect, and soil moisture. The data set is available from the Canoco for Windows 45 website as an Excel file named "Swiss plants.xlsx".
Here are the steps to perform a CCA with this data set:
Create a new project in Canoco for Windows 45 and name it "Swiss plants CCA".
Import the Excel file "Swiss plants.xlsx" to your project from the Data Editor. You will see two tabs: one for the response data (species abundance) and one for the explanatory data (environmental variables).
Select "CCA" from the Project Explorer and click on the "Run analysis" button in the Output Viewer.
In the dialog box that appears, select the response data tab ("Species") and the explanatory data tab ("Environment") as the input files. You can also choose to transform your data, center or standardize your variables, or apply a filter if needed.
Click on the "Next" button and select the explanatory variables that you want to include in your CCA model. You can also choose to perform a forward or backward selection of variables, or use an automatic model building procedure such as BEST or GLM.
Click on the "Next" button and select the options for permutation tests. You can choose to test the significance of your overall model, individual axes, or individual variables. You can also choose the type of permutation test (Monte Carlo, partial Monte Carlo, or restricted permutation) and the number of permutations.
Click on the "Finish" button and wait for the analysis to complete. You will see your results in graphical or tabular form in the Output Viewer.
The Output Viewer will show you several tabs with different types of output, such as:
The Summary tab, which gives you a brief overview of your analysis, such as the number of samples, variables, axes, and permutations.
The Eigenvalues tab, which shows you the eigenvalues and percentages of variance explained by each axis.
