Volcano Population Index.

These are countries identified by Ewert and Harpel (2004) and Small and Naumann (2001) as having a high Volcano Population Index (VPI; numbers of people living near to volcanoes), and higher population densities close to volcanoes than most other volcanically active regions.

We converted the series for the ith species, of length k, into k-1 values of Xi,j = log (Ii,j+1 / Ii,j), where Ii,j is the population index value for the year j and Ii,j+1 is the population index in the following year.

For each of the two groups of species, we calculated a multi-species population index from population indices for individual species, with the weight of the contribution of each species to the index being its absolute value of CLIMEns.

For each species, we had a time series of population index values, some of which were complete (data for all the years 1980 2005) and some of which had no index values for the early years.

Population indices based on visits to detection stations commonly are used to monitor wildlife populations.

Our simulation provides a flexible tool for the interpretation of station-based population indices.

Ewert and Harpel (2004) calculated populations in increasing radii circles centred on volcanoes to define Volcano Population Indices (VPI).

According to our results, VC and VW resulted in remarkable effects on host plant growth indices and on the other hand, integration of VC with LVC reduced nematode population indices to a great extent.

We created a flexible simulation environment to study the response of detection-based population indices under a wide variety of conditions meant to reflect species life history and study design.
