Amphibian dispersal maps - Alytes obstetricans
Swiss-wide map depicting the dispersal probability of the Midwife toad (Alytes obstetricans). Each grid cell indicates the relative probability that dispersing individuals will pass through that hectare on their way between known amphibian breeding sites. The map shows dispersal probability increasing along a scale from blue to yellow to red.
These maps should be thought of as heatmaps for dispersal activity of existing populations. In practical terms, these maps also show locations where potential new amphibian breeding sites have the highest chances of being colonized.
Areas with many populations in close proximity appear a darker red, reflecting the higher probability of dispersal as multiple dispersal routes between populations intersect. This feature of the maps deserves special attention. Lighter shades at the edges of the species' range do not necessarily indicate a weaker connection between populations, but rather a consequence of the lower density of breeding sites at the edges of the range. The color scale should be considered in the context of the immediate surroundings.
The dispersal map was calculated using Circuitscape and is based on a landscape resistance matrix derived from the best-ranked dispersal model for each species.
