[email protected] ABSTRACT — Herein, Alliphis geotrupes Ishikawa, 1979 is transferred to the genus Scarabacariphis Mašán, 1994 because of its free peritrematal shield (i.e. separated from the dorsal shield). The genus Scarabacariphis is redefined, and a key to the species of Scarabacariphis is provided, as well as additional morphological information for Scarabacariphis geotrupes comb. nov.

Soil Ecol. 9, 447– 452) in five natural forest reserves in eastern Austria. These sites were assumed to be stable and undisturbed reference habitats. The maturity indices of the gamasine communities were near their maximum in the investigated stands, and thus performed well towards the ‘‘high end’’ of the total range of the index. An occasionally inundated floodplain forest yielded much lower values. However, the correlation of the index with humus type, as proposed by Ruf et al. (Ruf, A., Beck, L., Dreher, P., Hund-Rienke, K., Ro¨mbke, J., Spelda, J., 2003. A biological classification concept for the assessment of soil quality: ‘‘biological soil classification scheme’’ (BBSK). Agric. Ecosyst. Environ. 98, 263–271) for managed forests, was not found. This indicates that the humus form is not a good predictor of the index over its entire range and is inappropriate to assess the fit of test communities. Fourteen percent of the species in this study were omitted from index calculation because adequate data for their families are lacking.

    Soil Mite Communities (Acari: Mesostigmata) As Indicators of Urban Ecosystems in Bucharest, Romania M

    www.nature.com/scientificreports OPEN Soil mite communities (Acari: Mesostigmata) as indicators of urban ecosystems in Bucharest, Romania M. Manu1,5*, R. I. Băncilă2,3,5, C. C. Bîrsan1, O. Mountford4 & M. Onete1 The aim of the present study was to establish the efect of management type and of environmental variables on the structure, abundance and species richness of soil mites (Acari: Mesostigmata) in twelve urban green areas in Bucharest-Romania. Three categories of ecosystem based upon management type were investigated: protected area, managed (metropolitan, municipal and district parks) and unmanaged urban areas. The environmental variables which were analysed were: soil and air temperature, soil moisture and atmospheric humidity, soil pH and soil penetration resistance. In June 2017, 480 soil samples were taken, using MacFadyen soil core. The same number of measures was made for quantifcation of environmental variables. Considering these, we observed that soil temperature, air temperature, air humidity and soil penetration resistance difered signifcantly between all three types of managed urban green area. All investigated environmental variables, especially soil pH, were signifcantly related to community assemblage. Analysing the entire Mesostigmata community, 68 species were identifed, with 790 individuals and 49 immatures. In order to highlight the response of the soil mite communities to the urban conditions, Shannon, dominance, equitability and soil maturity indices were quantifed. With one exception (numerical abundance), these indices recorded higher values in unmanaged green areas compared to managed ecosystems. The same trend was observed between diferent types of managed green areas, with metropolitan parks having a richer acarological fauna than the municipal or district parks.

The study was conducted in the Białowieża Forest, which is recognized as one of Europe’s last natural forest areas. Insects were caught over a period of 8 weeks in 72 attractant traps (type Intercept IPM). In total 1250 specimens of genus Tetropium were collected. We analyzed 524 beetles, including 295 specimens of T. castaneum and 229 specimens of T. fuscum. On 49 beetles (9.4%) there were 785 individuals of Trichouropoda shcherbakae (Trematuridae). Mites were more common on T. fuscum, which carried 82% of all collected deutonymphs. Most of the mites found on beetles were attached to their legs. This study reports on changes in the intensity of phoresy in time and location of mite deutonymphs on their host species.

In the Krka National Park, Brač Island, and near the town of Makarska, 320 samples were collected from various microhabitats: soil, grass and moss ground cover, wet moss, needle litter, moss covering tree trunks, and decaying wood). Altogether, 2097 mites of 56 gamasid species were recor- ded. Dominant species were: Polyaspis patavinus (Brač Island), Zercon fageticola (Makarska), and Chei- roseius serratus (Krka National Park). Analyses of ecological preferences and zoogeographic distribution were made for Polyaspis patavinus, Cheiroseius serratus, Zercon fageticola, Z. berlesei, Z. athiasi, Asca nova and A. aphidioides. Keywords: Gamasida, Acari, Croatia, biodiversity, zoogeography INTRODUCTION The Balkan Peninsula is located at the border of 2 regions of the Holarctic zone: Euro-Siberian and Mediterranean. Therefore, it could be expected that this is an area of interactions between faunas of both zoogeographical regions. Croatia, a country with a relatively small area, as a result of its location as well as its landscape and di- versifi ed climate, is distinguished by a mosaic of microhabitats, which favours high species diversity.

    Tri-Trophic Interactions of a Predator- Parasite-Host Assemblage in New Zealand

    Tri-trophic interactions of a predator- parasite-host assemblage in New Zealand BY KIRSTY JANE YULE A thesis submitted to Victoria University of Wellington in fulfilment of the requirements for the degree of Doctor of Philosophy Victoria University of Wellington (2016) 1 2 This thesis was conducted under the supervision of Associate Professor Kevin Burns (Primary Supervisor) Victoria University of Wellington, New Zealand 3 4 Abstract Parasites are ubiquitous and the antagonistic relationships between parasites and their hosts shape populations and ecosystems. However, our understanding of complex parasitic interactions is lacking. New Zealand’s largest endemic moth, Aenetus virescens (Lepidoptera: Hepialidae) is a long-lived arboreal parasite. Larvae grow to 100mm, living ~6 years in solitary tunnels in host trees. Larvae cover their tunnel entrance with silk and frass webbing, behind which they feed on host tree phloem. Webbing looks much like the tree background, potentially concealing larvae from predatory parrots who consume larvae by tearing wood from trees. Yet, the ecological and evolutionary relationships between the host tree, the parasitic larvae, and the avian predator remain unresolved. In this thesis, I use a system-based approach to investigate complex parasite-host interactions using A. virescens (hereafter “larvae”) as a model system. First, I investigate the mechanisms driving intraspecific parasite aggregation (Chapter 2). Overall, many hosts had few parasites and few hosts had many, with larvae consistently more abundant in larger hosts. I found no evidence for density- dependent competition as infrapopulation size had no effect on long-term larval growth. Host specificity, the number of species utilised from the larger pool available, reflects parasite niche breadth, risk of extinction and ability to colonise new locations.
