Mountains are important landforms with regard to both biodiversity and evolution of endemism. We analysed macro- ecological patterns of distribution and endemism of European montane (i.e. with at least 70% of their range inside mountain areas) mammals. The landscape of the study area was characterized by three environmental variables: land cover, land-use and elevation. For each species, we collected spatially explicit information on the extent of occurrence, level of endemicity, conservation status, habitat preferences, elevation range and all the available presence points.

1. Levels of endemism are usually expressed as percentage of endemics among all species recorded in a given area. Endemism levels also vary among taxa, yet inter-taxon variation in endemism levels has received much less attention. 2. We used the Italian tenebrionids to investigate how endemism levels vary among different but related lineages.

An updated inventory of the native vascular flora of Italy, providing details on the occurrence at regional
level, is presented. The checklist includes 8195 taxa (6417 species and 1778 subspecies), distributed in
1092 genera and 152 families; 23 taxa are lycophytes, 108 ferns and fern allies, 30 gymnosperms and 8034
angiosperms. The taxa currently occurring in Italy are 7483, while 568 taxa have not been confirmed in
recent times, 99 are doubtfully occurring in the country and 19 are data deficient. Out of the 568 not
