The predominant climate in the region according to the Gaussen classification is type 4aTh, (tropical hot, severe drought in the winter), having 7-8 dry months, with a xerothermic
index between 200 and 150, type BSwh (hot, semiarid climate, the rainy season starting only in the autumn).
Nolin also documents the impact of glaciers over Ohio and the changes that followed, especially the Xerothermic
Period when the "Prairie Peninsula" expanded into west-central Ohio.
sub-mediterranean deciduous oak forests occur, mainly dominated by Quercus frainetto, Q.
While studying the habitat of Phaneropterinae, Kocarek and Holusa (2006) observed that it occupies a wide range of open habitats from xerothermic
to wetlands and mostly consumed tall herb or lower shrub.

It is an herbaceous perennial plant well adapted to xerothermic
conditions of Southern Europe (Moglia et al., 2008; Raccuia et al., 2004) and typical conditions of arid and semi-arid areas of the Mediterranean environment (Raccuia et al.,2004; Gominho et al., 2001).
Floristically it is included in the Holarctic Kingdom and is shared between the Illyrian province of the Circumboreal Region (Polunin & Walters 1989), where the beech forests are dominant above 1000 m, with different vegetation series related to the substrate, and the Adriatic province of the Mediterranean Region with xerothermic
evergreen vegetation dominated by Pinus halepensis and Quercus ilex close to the sea level, and substituted by deciduous and thermophilous oaks when the sea influence decreases (Trinajstic 1995).

Arctosa lutetiana (Simon 1876) is an extra-mediterranean (including Ural) wolf spider that dwells in xerothermic
