Analysis of Types of Flea-Host Relations

AIS PARHOST1 permits making a query about statistics of different types of parasite-host relations of taxa of fleas and their hosts. An example of a summarizing table of relations of flea species of different families with species of the Leporidae family is given.

Analysis of the Flea-Host Relations in Zoogeographical Regions

The PARHOST1 system permits obtaining data on the number of flea species found on a particular host taxon in any of the 40 zoogeographical regions of the world. An example of such table is shown below.

The PARHOST1 system will develop in three directions.

The first direction is related to application of the block of geographic tables. This direction will permit accumulating and generalising primary information on flea distribution, which may be given in terms of physical or administrative geography. The PARHOST1 system will permit translating the names distribution ranges given in terms of physical geography into names expressed in terms of administrative geography.

The second direction of the AIS development envisages its integration with the block of processing of collection data and a complete realization of the block scheme given below.

The third direction will comprise creation of the block of morphological hierarchical classifiers for work on structural characters of fleas, separately and in connection with their distribution and parasite-host relations. The basis of this direction is the data on more than 150 skeletal flea structures (Medvedev, 1982; 1983; 1984; 1985; 1989; 1989a, b; 1992a, b; 1993; 1994; 1995a, b).
