| Soil invertebrate distribution in Araucaria forest, grassland and edge habitats was studied in both disturbed and undisturbed areas in southern Brazil. Mean-density and taxa compositions were verified. Invertebrate densities differed between grassland and the other two habitats in the undisturbed area but not across the disturbed one. At the disturbed area taxa differed between the grassland and the other two habitats. The undisturbed area, on the other hand, presented taxa differences only between the grassland and the forest habitats. Acari, Arachnida and Collembola were the most sensitive taxa for detecting differences across habitats in both areas. At the disturbed area, these taxa presented densities lowering from the forest to the grassland. At the... |

| The abundance of soil microarthropods from seven fragments of Araucaria Forest, Muitos Capões, Rio Grande do Sul, Brazil, was compared. The size of the fragments ranged from 0.25 ha to 35 ha, the two largest fragments are situated within the Aracuri Ecological Station and the remaining five are situated in a cattle ranching farm. In June 2000, three plots (10 m x 10 m) were established in the central area of each patch, and three soil cores (7 cm diameter x 6 cm deep) were taken per plot. The abundance of microarthropods in the upper six centimeters (soil + litter) varied between 63209 and 102704 ind.m-2, with oribatid mites (Acari, Cryptostigmata) being dominant in all fragments (between 46.9 % and 61.3 % of total individuals). Most microarthropod groups... |

| The springtails of the Netherlands: genus Orchesella (Hexapoda: Entognatha: Collembola) This is the first in a series of publications on the identification, distribution and ecology of springtails of the Netherlands. In this paper the genus Orchesella Templeton, 1835 is described, which is with four native species present in the Netherlands, i.e. O. cincta (Linnaeus, 1758), O. flavescens (Bourlet, 1839), O. quinquefasciata (Bourlet, 1841), and O. villosa (Geoffroy, 1762). A fifth species, i.e. O. bifasciata (Bourlet, 1839) is expected, but has not been recorded yet. A key to the Dutch species is provided. A database was built up, containg 1037 verified museum records, literature records and personal observations. For each species a distribution map,... |

| Uit Nederland zijn ruim 200 soorten springstaarten bekend, maar er zijn nog veel nieuwe soorten te verwachten. Deze verwachting is vooral gebaseerd op meldingen van springstaarten uit Denemarken, Duitsland en België, in biotopen die ook bij ons te vinden zijn. In de winter van 2007 werd op een ruderaal terrein in Westzaan Bilobella braunerae ontdekt, een nieuwe soort (en nieuw genus) voor ons land. In dit derde artikel in de serie springstaarten van Nederland worden de twee verwante genera Bilobella en Neanura geïntroduceerd, waarbij de nieuwe soort wordt behandeld. Met de determinatiesleutel zijn de Nederlandse soorten uit de subfamilie Neanurinae, plus de verwachte soorten op naam te brengen. |

| The springtails of the Netherlands: genus Ptenothrix, new to the Dutch fauna (Hexapoda: Entognatha: Collembola) This paper is the second in a series on the identification, distribution and ecology of springtails of the Netherlands. The genus Ptenothrix Börner, 1906 is described, with one new species present in the Netherlands, i.e. P. atra (Linnaeus, 1758). A second and third species, i.e. P. ciliata Stach, 1957 and P. setosa (Krausbauer, 1898) may be expected for the Dutch fauna, but have not been recorded yet. With a key, illustrated with drawings and photographs, specimens of Ptenothrix can be identified. For P. atra a distribution map, with a resolution of 5km squares is added. For each species an ecological profile is made. Ptenothrix atra is... |

| The following three species are redescribed: Sminthurus viridis (Linnaeus, 1758), Sminthurus nigromaculatus Tullberg, 1871, and Sminthurus multipunctatus Schäffer, 1896. Four new species are described from France and Spain: Sminthurus bourgeoisi n. sp., Sminthurus bozoulensis n. sp., Sminthurus leucomelanus n.sp.,and Sminthurus hispanicus n. sp. The importance of the ontogeny of chaetotaxy is stressed. Indeed, not all species acquire the secondary chaetotaxy in the same instar, and for these characters the most informative instar is not the adult but the third juvenile instar. The study of such characters involves the clustering of similar characters. A short discussion is given about this issue (selection of characters and clustering criteria). |

| In een recent artikel werd het springstaartengenus Ptenothrix besproken, met een nieuwe soort voor de Nederlandse fauna: P. atra. Na toezending van het artikel aan de Belgische springstaartenspecialist Frans Janssens kwam er een mailtje retour met de opmerking dat op de foto’s P. ciliata te zien is en niet P. atra! De lichte tekening op de rugzijde is (binnen Europa) uniek voor P. ciliata en is afwezig bij P. atra. Nadere bestudering van exemplaren van verschillende vindplaatsen in Nederland en gebruik makend van recent gepubliceerde kenmerken bevestigen dat P. ciliata en niet P. atra voorkomt in Nederland. Dit artikel introduceert P. ciliata, met tekeningen van nieuwe determinatiekenmerken en geeft een rectificatie op het eerder verschenen artikel over... |

| Phylogenetic studies on several groups of arthropods, such as Acari (mites) or Collembola (springtails), make wide use of chaetotaxy. Chaetotaxic characters, besides being morphological features (setal shape), often have a binary nature, that is presence vs. absence. A seta can be variable in a population, and one may attribute a presence probability to this seta. In fact, the presence probability should be defined for each instar. One might think that a variable seta corresponds to a polymorphism (e.g., two or more alleles in a population); in fact, setal variability should be regarded as the result of a propensity intrinsic to individuals, i.e., a potentiality being expressed at random among specimens. The phenomenon known as lateral inhibition explains... |

| The biodiversity of soil communities remains very poorly known and understood. Soil biological sciences are strongly affected by the taxonomic crisis, and most groups of animals in that biota suffer from a strong taxonomic impediment. The objective of this work was to investigate how DNA barcoding - a novel method using a microgenomic tag for species identification and discrimination - permits better evaluation of the taxonomy of soil biota. A total of 1,152 barcode sequences were analyzed for two major groups of animals, collembolans and earthworms, which presented broad taxonomic and geographic sampling. Besides strongly reflecting the taxonomic impediment for both groups, with a large number of species-level divergent lineages remaining unnamed so far,... |

| The objective of this work was to elevate gradient effect on diversity of Collembola, in a temperate forest on the northeast slope of Iztaccíhuatl Volcano, Mexico. Four expeditions were organized from November 2003 to August 2004, at four altitudes (2,753, 3,015, 3,250 and 3,687 m a.s.l.). In each site, air temperature, CO2 concentration, humidity, and terrain inclination were measured. The influence of abiotic factors on faunal composition was evaluated, at the four collecting sites, with canonical correspondence analyses (CCA). A total of 24,028 specimens were obtained, representing 12 families, 44 genera and 76 species. Mesaphorura phlorae, Proisotoma ca. tenella and Parisotoma ca. notabilis were the most abundant species. The highest diversity and... |

| The objective of this work was to compare the oribatid mite and springtail communities in three plots with different soil use - Coffee (CP), secondary vegetation or fallow fields (acahual, A) and a cloud mountain forest (CMF) - within a coffee plantation located in Santa Maria Huatulco, Oaxaca State, Mexico. In each plot 20 samples (10 of soil, 10 of litter) were taken and processed in Berlese funnels. The extracted fauna was preserved in 70% ethanol. A total of 3,031 oribatid mites belonging to 33 species, and 1,177 specimens of springtails belonging to 43 species, were collected. The number of species recorded was: 27 at CP (14 oribatids; 13 springtails), 44 at A (19 oribatids; 25 springtails) and 62 at CMF (32 for each group). A total of 26 oribatid and... |

| The results of ecological restoration techniques can be monitored through biological indicators of soil quality such as the leaf litter arthropod fauna. This study aimed to determine the immediate effect of brushwood transposition transferred from an area of native vegetation to a disturbed area, on the leaf litter arthropod fauna in a degraded cerrado area. The arthropod fauna of four areas was compared: a degraded area with signal grass, two experimental brushwood transposition areas, with and without castor oil plants, and an area of native cerrado. In total, 7,660 individuals belonging to 23 taxa were sampled. Acari and Collembola were the most abundant taxa in all studied areas, followed by Coleoptera, Diptera, Hemiptera, Hymenoptera, and Symphyla.... |
