This paper reports on three species of mites of the genus Laelaspis in Iran - Laelaspis calidus Berlese from Pheidole pallidula, Laelaspis humeratus (Berlese) from Tetramorium caespitum and Laelaspis dariusi Joharchi & Jalaeian, sp. n. fromsoil. The new species is described and illustrations provided.

Characterisation of fractured rocks and evaluation of fracture connectivity are essential for the study of subsurface flow and transport in fractured rock aquifers. In this study, we use a new method to present fracture networks and analyse the connectivity of the fractures, based on the technique of randomly-generated realisations. The application of the method aims to provide more detailed in...

The generic concepts of Archaeoteleia Masner and Proteroscelio Brues are expanded to accommodate two new species that are here described: Archaeoteleia astropulvis Talamas sp. n. and Proteroscelio nexus Talamas sp. n. A specimen of Archaeoteleia from Baltic amber is illustrated and discussed. Diagnoses of Proteroscelio, Proterosceliopsis Ortega-Blanco, McKellar & Engel and Bruescelio Ortega-Bla...

Palaearctic species of Periclistus Förster has been systematically described, but a new inquiline gall-wasp, Periclistus qinghainensis sp. n., is described from China. This species was obtained from an unknown stem gall induced on Rosa sp. Diagnosis, distribution and biology of the new species are described in this paper. After examining the types of Periclistus idoneus Belizin, 1973 and Pericl...

The goal of this paper is to provide background, heuristics and motivation for several conjectures of Deligne [12, 8.2, p. 163], [12, 8.9.5, p. 168] and [23, p. 300] and Goncharov [15, Conj. 2.1], presumably along the lines used to arrive at them. A complete proof of the third and fourth of these conjectures and partial solutions of the first two are given in [19]. A second goal of this paper i...

The type species of the genus Akiodoris, A. lutescens, Bergh, 1880 is redescribed from specimens found in the Sea of Okhotsk, and from the Commander Islands, Russia. A second species in the genus, Akiodoris salacia Millen sp.nov., is described from the Pacific waters off British Columbia, Canada. The type species of the genus Armodoris, A. antarctica Minichev, 1972 from the Davis Sea, is redesc...

New mythicomyiids from Baltic and Rovno amber are described and illustrated herein including one new genus: Riga, n. gen.; and five new species: Glabellula aggregata Evenhuis, n. sp., Glabellula perkovskyi Evenhuis, n. sp., Riga toni Evenhuis, n. sp., Carmenelectra shehuggme Evenhuis, n. sp. and Carmenelectra pernigra Evenhuis, n. sp. The genus Riga is very closely related to the extant genus R...

Numerous studies of host starvation have emphasized pathological effects of parasites on their insect host, but little attention has been focused on the effects of host starvation on the parasites. This study addressed the possibility that parasite life-cycle events could be manipulated by withholding food from the host. The system used was Gregarina niphandrodes (Apicomplexa: Eugregarinida) in...

Companies have moved away from vertical integration, in which a single company converts raw materials into products for end users, to an increasing reliance on supply chains. A typical U.S. company purchases 55% of the value of its products from other companies (Dyer & Singh, 1998). The promise of greater efficiency and the ability to adapt to increasingly volatile market dynamics have prompted...
