Oribatid mite (Acari: Oribatida) communities of urban brownfields in Tallinn, Estonia, and their potential as bioindicators of wasteland successional stage

Piret Vacht, Helin Niglas, Annely Kuu, Tiiu Koff, Sander Kutti & Jane Raamets
Urban brownfields are ecologically valuable ecosystems that have been and are under various anthropogenic influences. Because brownfields are subject to rapid development in urban areas, their biological communities, including soil mesofauna, are overlooked and seldom researched, even though they could provide valuable insight into the ecological functioning of these areas. This exploratory study describes the community characteristics of oribatid mite fauna of 12 brownfields in Tallinn, Estonia, and analyzes the potential of oribatid mites as...

Microarthropods in australian sugarcane soils: A survey with emphasis on the Mesostigmata as potential regulators of nematode populations

David E. Walter & G.R. Stirling
Sugarcane is attacked by a suite of nematode pests, but little is known of the mites and other soil microarthropods that feed on them. To address this deficit, we undertook a survey of the soil microarthropod fauna in 60 sugarcane fields in Queensland, Australia. The results showed that oribatid mites and springtails dominated the upper 10 cm of sugarcane mineral soils. Laboratory observations demonstrated avid nematophagy in Galumnidae (Galumna sp., Pergalumna sp.), Scheloribatidae (Scheloribates sp.),...

An instance of Boiga dendrophila dendrophila (Boie, 1827) (Reptilia: Colubridae) being parasitized by Amblyomma helvolum Koch, 1844 (Acari: Ixodidae), with comments about the attachment sites of this tick species

Jean-Jay Mao, Gerrut Norval, Richard G. Robbins & Siew Te Wong
Ectoparasites, such as ticks, may exhibit preferences for particular attachment sites on various hosts, since the choice of attachment sites may affect tick survival. Herein we report an instance of a mangrove snake, Boiga dendrophila dendrophila, being parasitized by the tick Amblyomma helvolum, with comments on this tick’s attachment sites. Our collection of A. helvolum appears to be the first record of this species from Sandakan, a city on the northeast coast of Borneo, in...
