Ecology of the grasshopper assemblages is well
researched worldwide. Pattern of the orthopteran
assemblages is strictly determined by the pattern of the
habitattypes (Joern, 1982; Kemp, 1992). Significant
factors in this repetitive pattern are regionally the
landscapestructure (Hjerman and Ims, 1996) and the
macroclimate (Köhler et al., 1999), locally the habi
tatstructure, the microclimate and the landuse (Kis
benedek, 1992; Guido and Chemini, 2000).
Organization of orthopteran assemblages is influ
enced by further factors, such as interspecific compe
tition (Rácz, 1979), predation (Belovsky and Slade,
1993), ecotone effect (Szövényi, 2006) and distur
bances (Bieringer, 2002).
Habitatstructure affects the structure of the ortho
pteran assemblages by the conditions of the soil and
the vegetation. Although soil conditions determine the
presence and abundance of species which lay their
eggs in that (Schell and Lockwood, 1997), the hori
zontal and vertical structure of the vegetation is the
most determinant factor for all species (Joern, 1979;
Fielding and Brusven, 1993). Vegetation cover is defi
nitely seen in percentage rate of geophilous and
graminicol species (Ingrisch and Köhler, 1998), but
lifeform spectra of the assemblages are mainly influ
enced by the vertical structure of the vegetation (Wing
erden et al., 1992; Varga, 1997).
The article is published in the original.
Influences of the species composition and diversity
of the vegetation have also been detected (Fielding and
Brusven, 1993; Haddad et al., 2009). According to
Bauer and Kenyeres (2006b) abundances of Isophya
species are related to the cover of the mesophilous
dicotyledonous plant species.
Microclimate dependency of the organization of
the orthopteran assemblages is well known (Dreux,
1962; Kemp, 1992; Kenyeres et al., 2009). Climatic
requirements, including cold effect, dormancy, tem
perature tolerance of the imagos are present in all state
of the ontogenesis (Willott and Hassall, 1998). Micro
climate dependence is partly based on that the dry cli
mate reduces the risk of fungal infection (e.g.
(Metschnikov) Sorokin 1883) (Hernandez
Crespo and SantiagoAlvarez, 1997). Further, the
complexity of the organization of orthopteran assem
blages is improved by the interrelationships of the veg
etation and the microclimate (Cox and Moore, 1980;
Stoutjesdijk and Barkman, 1992).
Main hypotheses of this study were: (1) changing of
structural features in the orthopteran assemblages is
continuous, so they are characterized by several mixed
or transitional assemblagetypes; (2) organization of
the studied assemblages is dominated by factors being
uniform globally moderated by locally.

—Our case study revealed that organization of the studied local assemblages is dominated by mech
anisms uniform globally, from which in CentralEurope (1) vegetation height, (2) overall vegetation cover,
(3) cover of the dicotyledonous and mesophilous monocotyledonous species, (4) microclimate, (5) annual
rainfall and (6) insolation in April have main importance. Lifeform– and ecotypestructure of the assem
blages in habitats characterized by similar vegetationstructure and microclimate seem to be conservative at
Eurasian scale, but speciescomposition of the local variants is determined by individual effects of zoogeog
raphy, landscape structure, landuse and habitathistory.
