Learning outcomes
In order to pass the course (grade 3) the student should be able to
- master the power and logarithm laws;
- know the definition of the derivative and be able to compute the derivative of simple functions and to use the derivative as a tool for determining extreme values;
- solve first and second order linear difference equations with constant coefficients;
- determine stable equilibria of simple discrete dynamical systems;
- solve simple separable differential equations, in particular the logistic equation;
- solve systems of linear equations, master matrix calculus and know how to compute eigenvalues and eigenvectors;
- apply the mathematical methods covered by the course on biological models;
- use foundations for statistical investigations and know some methods for descriptive statistics;
- use basic statistical concepts and methods that are common in quantitative biology, and have a general understanding of applications of statistics in some areas of biology;
- use simple mathematical and statistical software.
Content
Powers, logarithms, allometry. The exponential function, exponential growth, difference equations. The derivative: definition, rules, derivatives of higher order, the mean value theorem, the connection between the sign of the derivative and increase/decrease of the function. Maximisation problems. Taylor’s formula. Population dynamics and discrete dynamical systems, the logistic model and the Ricker model. Matrices, vectors and linear systems of equations, determinants, eigenvalues and eigenvectors with demographic models as application. Differential equations: separable, linear and systems of linear equations. Briefly about partial differential equations.
Population, sample, natural variation. Ideas behind hypothesis-testing. Replicated experiments. Descriptive statistics. Discrete and continuous data. General ideas on sampling. Statistical tests, the binomial distribution and the sign test. The normal distribution. Estimation of mean, variance and deviation. The t-distribution, briefly about Poisson, exponential and chi2 distributions. Tests for one and two normal distributions. Paired observations. One-way and two-way analysis of variance, randomized blocks. Multiple comparisons. Correlation. Simple linear regression. Chi2 test. Wilcoxon’s rank sum test. Mathematical software.
