The weevils were collected by sifting the litter, surface layer of soil and remnants of twigs at five study sites affected by human activities. The trees growing at these sites were 40-100 years old. We recorded a total of 44 weevil species classified within 28 genera and 3 families. The number of species found at particular sites ranged from 17 to 26. The mean abundance (density) of weevils varied from 5.8 to 23.9 ind.m-2 of the soil surface. The geobionts Barypeithes chevrolati, Acalles echinatus and A. commutatus were the predominating species. The abundance dynamics of weevils showed two distinct peaks. The first peak observed in April or May was followed by the second peak in August or September, respectively. Typical geobionts within the genera Barypeithes and Brachysomus largely shared in the abundance maximum in the spring. The high proportion of saproxylic species belonging to the genera Acalles and Ruteria significantly contributed to the abundance maximum in the late summer and in the autumn. The weevil assemblages were characterized by the high share of stenotopic, hygrophilous, geobiont, polyphagous, saproxylic and apterous (non-flying) species. European (34 %), Holarctic (18 %) and Palaearctic (16 %) species were the most frequent. Several records of weevil species, namely those of Kyklioacalles suturatus, Stomodes gyrosicollis, Simo variegates, Brachysomus dispar, Trachyphloeus scabriculus, are of faunistic interest.10aCurculionoidea1 aHolecova, Milada1 aZach, Peter1 aKardosova, Jana  uhttps://weevil.myspecies.info/epigaeic-weevils-coleoptera-curculionoidea-oak-hornbeam-forests-vicinity-bratislava-sw-slovakia01617nas a2200205   4500008004500000020001400045245015000059210006900209260000900278300001000287490000700297520084400304653002301148653002301171653002201194100002101216700001701237700002201254856013501276       2008                        Engldsh    a0015-549700aKaryotype analysis of three weevil species from the genera Brachysomus (Boheman, 1845) and Strophosoma Billberg, 1820 (Coleoptera, Curculionidae)0 aKaryotype analysis of three weevil species from the genera Brach  c2008  a25-290 v563 aKaryotypes of three weevil species, viz.

The karyotype structures of the two bisexual and one parthenogenetic species are described for the first time. Most chromosomes are meta- or submetacentric. In the two species ofthe genus Brachysomus, the chromosomes resemble one another in having a rather small amount of heterochromatin restricted to the pericentromeric region, visible as dark stained blocks mainly during the early stages of nuclear division. Larger bands at mitotic metaphase and diakinesis occur only in Strophosoma faber.

A total of 20 weevil species (belonging to three families: Anthribidae, Apionidae, Curculionidae) were recorded, of which 14 species (70%) are arboricolous as adults. Pine specialists and wider specialists of coniferous trees were represented by eleven species. The pine specialist Brachyderes incanus was the predominating and euconstant species.

The investigation was performed on 10 study plots (forest stands of the age from 40 to 100 years) in the Male Karpaty Mts and Trnavska pahorkatina hills, SW Slovakia. Each site was affected, to some extent by human activities of which forest fragmentation and pollution with calcareous dust were the most important. The soil macrofauna was collected by sifting the litter, surface layer of soil and remnants of twigs. Altogether 4,090 individuals of weevils classified into 78 species, 43 genera and 4 families were recorded. The number of species found at the particular sites ranged from 22 to 31 species. The mean abundance of weevils varied from 2.09 to 49.71 ind.m-2. Geophilous species Ceutorhynchus pallidactylus, geobionts Acalles fallax, Barypeithes chevrolati, Barypeithes mollicomus, Brachysomus hirtus, Trachodes hispidus and geoxenes Ceutorhynchus obstrictus and Sitona macularius predominated in the material from the oak-hornbeam forest epigeon. The canopy architecture and content of exchange bases in the leaf litter from amongst 13 gradient and 2 categorial variables analysed had direct and significant influence on the structure of epigeic weevil assemblages. The forest fragmentation caused increase the abundance of herbicolous, euryhygric and ubiquitous species in the epigeon of island woods. The weevil community was less abundant and unstable in the forest site polluted with calcareous dust.1 aHolecova, Milada1 aNemethova, Danka1 aKudela, Matus  uhttps://weevil.myspecies.info/structure-and-function-weevil-assemblages-coleoptera-curculionoidea-epigeon-oak-hornbeam-forests-sw00599nas a2200133   4500008004100000020001400041245015800055210006900213260000900282300001100291490000700302100002100309856013500330       2007                        eng d  a1335-121400aBiodiversity of weevil fauna (Coleoptera, Curculionoidae) and their assemblage structure in the herbage undergrowth of the Carpathian oak-hornbeam forest0 aBiodiversity of weevil fauna Coleoptera Curculionoidae and their  c2007  a95-1090 v191 aHolecova, Milada  uhttps://weevil.myspecies.info/biodiversity-weevil-fauna-coleoptera-curculionoidae-and-their-assemblage-structure-herbage-undergrow00684nas a2200169   4500008004500000020001400045245012400059210006900183300001000252490000700262653002300269653002500292653002200317653001900339100002100358856013500379       1993                        Engldsh    a1335-589900aBagous bagdatensis Pic 1904 (B. wagneri Dieckmann 1964) (Curculionidae, Coleoptera) - a little known Palaearctic weevil0 aBagous bagdatensis Pic 1904 B wagneri Dieckmann 1964 Curculionid  a73-800 v2410aBagous bagdatensis10aBagous glabrirostris10aBagous lutulentus10aBagous wagneri1 aHolecova, Milada  uhttps://weevil.myspecies.info/bagous-bagdatensis-pic-1904-b-wagneri-dieckmann-1964-curculionidae-coleoptera-little-known-palaearct01782nas a2200205   4500008004500000020001400045245015000059210006900209260000700278300001000285490000900295520111300304653002201417653001901439653002301458100002201481700001701503700002101520856003501541       2009                        Engldsh    a1175-532600aChromosomal similarities and differences among three sibling species of the Acalles echinatus group (Coleoptera, Curculionidae, Cryptorhynchinae)0 aChromosomal similarities and differences among three sibling spe  c21  a63-680 v19853 aIn order to clarify the taxonomic position of three sibling species of weevils from the Acalles echinatus group, A. echinatus, A. fallax and A. petryszaki, cytogenetic relationships are investigated by studying the mitotic and meiotic chromosomes, including the localisation of heterochromatin by C-banding, as well as the localisation of NORs by silver impregnation. These sources of data are congruent and strongly support that the examined species are closely related. All examined species are characterised by a karyotype of the same chromosome number and sex determination system but with different morphology of chromosomes. All the analysed features, such as the centromeric index, relative length, C-bands and NORs, show that the structure of the karyotype of A. echinatus is more similar to that of A. petryszaki, whereas the karyotype of A. fallax is divergent. The higher chromosome number (2n = 30) in relation to the modal formula in Curculionidae (2n = 22) suggests that karyotype evolution in these species could have occurred by centric fissions of metacentric elements leading to acrocentry.10aAcalles echinatus10aAcalles fallax10aAcalles petryszaki1 aLachowska, Dorota1 aRozek, Maria1 aHolecova, Milada  uhttp://www.mapress.com/zootaxa
