Abstract: Nestedness is a common pattern in nature, where less species rich local communities are subsets from richer communities. Is this predictability of community composition holds after the loss of species? This problem was investigated by excluding the rarest species of four example metacommunities (collections of local communities within archipelagoes), and correlated the changes of nestedness with the loss of species and individuals. Rarest species is that with the least number of individuals. Nestedness declined after a small increase in two of the metacommunities with the exclusion of species, and reached random species composition in both metacommunities after the loss of 58–66% of species. The order of nested subset structure in the other two metacommunities increased until most of the species were excluded (76% and 92%). The loss of 7–30% of individuals from the rarest species in all metacommunities led to random compositions. Because the extinction of ca. half of the species has been observed in a variety of human disturbed communities, the loss of compositional predictability of metacommunities may be an important threat in the increasingly human dominated communities.

Abstract: Allozyme polymorphism was studied in four samples of Isophya kraussi (Brunner von Wattenwyl, 1878), a brachipterous, sedentary tettigonoid species. Three samples were collected in the Aggtelek Karst region (Haragistya 1998, Mogyoróskuti meadows 1999 and 2001) and one in the Zemplén Mts (Gyertyánkúti meadows 1998–1999). Enzyme polymorphism was investigated by polyacrylamide gel electrophoresis. All 10 scorable loci (Aldox, Est, Got, alpha-Gpdh, Hk, Idh, Mdh, Me, Pgi and Pgm) had alternative alleles in at least one sample. We detected a high level of polymorphism. On average, more than 60% of the investigated loci were polymorphic and the average number of alleles was about 2.1. The average heterozygote frequency was also high approximately 0.19. Large FIT values indicated a considerable level of genetic variation as well. The larger part of the total variation was explained by the within sample component and a relatively smaller portion of it was attributable to the between sample component. Many of the FIS values were positive indicating some heterozygote deficiency. In the analysis of spatial variation, we obtained highly significant FST values, which suggested strong genetic differentiation between the local populations. In contrast, the FST value calculated in the temporal analysis of variation was not significant. The average value of Nei"s genetic distances between pairs of samples of geographically distinct populations was 0.071 while, that estimated within the Mogyoróskút population was 0.027. Thus, the results of all analyses indicated a higher level of differentiation among the geographically distinct populations than between the two samples collected in a single population in different years. The results of the PCA analyses fully confirmed those obtained in other analyses.

Abstract: Nine species of digenetic trematodes are reported: Lintonium vibex (Linton, 1900) Stunkard et Nigrelli, 1930 from Lagocephalus lunaris (Tetraodontidae), Complexobursa vjetnamensis Oshmarin et Mamaev, 1963 from Terapon theraps (Teraponidae); Monascus filiformis (Rudolphi, 1819) Looss, 1907 (new synonyms: M. americanus Amato, 1982, M. mediolongiusculus Ding, 1993) from Selaroides leptolepis (Carangidae); Tergestia pauca Freitas et Kohn, 1965 from Alepes djedaba (Carangidae); Transverstotrema licinum Manter 1970 from Diplodus noct (Sparidae); Treptodemus latus Manter, 1961 from Hemiramphus marginatus (Hemiramphidae); Prosogonotrema bilabiatum Pérez Vigueras, 1940 from Epinephelus areolatus (Serranidae); Hexangium sigani Goto et Ozaki, 1929 from Siganus canaliculatus (Siganidae) and Diphterostomum brusinae (Stossich, 1899) Stossich, 1903 from Argyrops spinifer (Sparidae). All those species except Tergestia pauca and Hexangium sigani represent new geographic records.

Abstract: A redescription, rank elevation, and lectotype designation of the neglected taxon Ponera coarctata var. testacea Emery, 1895 are published. Two different morphometric approaches resulted in a clear separation of testacea from its sister species coarctata (Latreille, 1802). P. testacea is abundant in the Mediterranean region but is also widely distributed in Central Europe where it spreads north to 51º30"N. It is more xerothermophilic than coarctata and seems to avoid shaded, moister woodland habitats.

Key words: Ponera, lectotype, morphometric

Abstract: Type species are designated for following taxa described after 1930: subgenera Macradesmia, Oteroscelopsis, Macropodesmia of Adesmia Fischer von Waldheim, subgenus Catomodontus of Catomus Allard, subgenus Cyphostethoides of Cyphostethe Marseul, subgenus Saxistena of Mesostena Eschscholtz, subgenus Subtentyrina of Tentyria Latreille, genera Lepidocnemeplatia, Pseudopachyscelis, and Tetranosis. An erroneous type species designation for Scleronimon Reitter is corrected. The genera Platyscelis Latreille and Oodescelis Motschulsky are based on the same type species, leading to description of Kaszabosceli<%0>s <%-1>gen. n., and to numerous new combinations. Scleropatrum Reitter and Monatrum Reichardt are synonymized, and Scleropatroides gen. n. is described to include species formerly included in the genus Scleropatrum: authors, not Reitter, 1877.
