Methods for the Analysis of Data on Habitat Selection of the Included Species

Abstract

For each group of animals seen, the habitat in which they were observed was classified according to various environmental factors. These parameters, which referred to each observation and which included data on topography, vegetation and weather conditions, were called observation factors (see Chap. 7.1, p. 55). For geographical location I have used the coordinates of the hectare field in which the group was observed. As each hectare field of the grid-pattern system was classified according to ecological parameters these factors could be used in conjunction with the above observation factors. To distinguish them, they were known as field factors (see Chap. 7.3, p. 62). The following describes which dependent variables were used in connection with the observation factors and/or the field factors, the two types of independent variables.
