Course objectives
We will learn how to analyse ecological and biogeographical data in order to correctly test hypotheses stated in bachelor or diploma theses. This course focuses on basic and advaced numerical analytical methods, which are commonly used in biogeographical studies. Special attention will be paid to data manupulation and application of statistical methods in R environment. After the completing of the course, students will be able to manipulate and analyse their data in ArcGIS and R softwares. They will be also able to present and interpret the resuts of the analyses.
Learning outcomes
After the completing of the course, students will be able to manipulate and analyse their data in ArcGIS and R softwares. They will be also able to present and interpret the resuts of the analyses.
Syllabus
  • Here is a preliminary outline of the course, however, all points are subject to change, because I expect deeper focus on R or GIS, depending on students' requirements.
  • 1. Introduction to the course – ouline; literature; software; sample data; instalation of the following softwares: R, R Studio, AcrGIS, SAM; overview of biogeographical and environmental data.
  • 2-4. Introduction to R – basic operations with R, vectros, matrices, data frames a lists, cycles in R, data import from ArcGIS, descriptive statistics (boxplots, histograms etc.), simple maps in R, data transformations and standardizations.
  • 5. GIS in biogeography and ecology – data processing and EDA in ArcMap and/or R, vector vs. raster data, data import and conversions, ArcGIS database, coordinate systems, digital evelation models + derivation of ecologically menaningful indices (Terrain Ruggedness, Heat load index, Topographic wetness index), landscape metrics, Toolboxes for ArcGIS, overlay algebra.
  • 6. Correlation and regression analysis in R – correlation coefficients (Pearson's and Spearman's cefficients), linear regression models, variation partitioning (R2 and adjusted R2), selection of explanatory variables (Forward selection), generalized linear models (GLM, logistic regression). Correlation of distance matrices (Mantel correlation). Calculations in R and SAM.
  • 7. Machine-learning methods - CART + Random Forests - classification and regression trees (CART), Random Forests, model evaluation (k-fold cross-validation, bootstrapping). Applications in R and MaxEnt.
  • 8. Species distribution modelling - modelling species ditribution (presence-absence data) with MaxEnt.
  • 9. Similarity and distance indices – Jaccard, Sørensen, Bray-Curtis, βsim, Euclidean distance, Hellinger distance), calculation of distance matrix in R, NMDS for visualization of distance matrices.
  • 10. Numerical classifications – methods of hierarchical classification (Single linkage, Complete linkage, UPGMA, Ward's method, β flexible), non-hierarchical classification (k-means), spatially constrained classification. Applications in R.
  • 11. Gradient analysis – linear vs. unimodal methods, direct vs. indirect ordination analysis with particular focus on Principal Component Analysis (PCA), Principal Coordinate Analysis (PCoA). Varibale testing (Monte Carlo permutation test), covariates and partial ordination. Applications in R.
  • 12. Spatial autocorrelation – measuring in univariate data (Moran’s I), measuring in multivariate data (Mantel correlation), effect of spatial autocorrelation on results of statistical tests, spatial proximity/distnace in numerical analyses (XY, spatial polynoms, PCNM, MEM variables). Applications in R and SAM.

Teaching methods
Theoretical lectures accompanied by practical applications in R and other softwares (ArcGIS, SAM, etc.).
Assessment methods
To pass the exam student must prove the ability to analyse the data using statistical methods and prepare short study. Detail instrictions will be communicated during the semester. The exam will consist of discussion on the methods used for data analysis including deeper theoretical background.
