Potential and limitations of X-Ray micro-computed tomography in arthropod neuroanatomy: A methodological and comparative survey
- Andy Sombke, Elisabeth Lipke, P. Michalik, G. Uhl, S. Harzsch
- Biology, Medicine
- The Journal of comparative neurology
- 2 March 2015
Classical histology or immunohistochemistry combined with fluorescence or confocal laser scanning microscopy are common techniques in arthropod neuroanatomy, and these methods often require… Expand
Evolutionary morphology of the male reproductive system, spermatozoa and seminal fluid of spiders (Araneae, Arachnida)--current knowledge and future directions.
- P. Michalik, M. Ramirez
- Biology, Medicine
- Arthropod structure & development
- 1 July 2014
The male reproductive system and spermatozoa of spiders are known for their high structural diversity. Spider spermatozoa are flagellate and males transfer them to females in a coiled and… Expand
Silhouettella loricatula (Arachnida, Araneae, Oonopidae): A Haplogyne spider with complex female genitalia
- M. Burger, W. Graber, P. Michalik, C. Kropf
- Biology, Medicine
- Journal of morphology
- 1 June 2006
The female genital system of the oonopid Silhouettella loricatula is astonishingly complex. The genital opening is situated medially and leads into an oval receptaculum that is heavily sclerotized… Expand
Cephalic modifications in dimorphic dwarf spiders of the genus oedothorax (Erigoninae, Linyphiidae, Araneae) and their evolutionary implications
- P. Michalik, G. Uhl
- Biology, Medicine
- Journal of morphology
- 1 July 2011
Reproductive competition among males selects for a broad variety of strategies and traits from mate guarding to nuptial food gifts. Males of many dwarf spider species possess conspicuous secondary… Expand
On the occurrence of coenospermia in mesothelid spiders (Araneae: Heptathelidae).
- P. Michalik, J. Haupt, G. Alberti
- Biology, Medicine
- Arthropod structure & development
- 1 April 2004
Two species of the early derivative spider family Heptathelidae (Heptathela kimurai yanbaruensis and Ryuthela nishihirai nishihirai) have been investigated with respect to spermiogenesis, focussing… Expand
The male genital system of the cellar spider Pholcus phalangioides (Fuesslin, 1775) (Pholcidae, Araneae): development of spermatozoa and seminal secretion
- P. Michalik, G. Uhl
- Biology, Medicine
- Frontiers in Zoology
- 29 June 2005
BackgroundMost arthropods pass through several molting stages (instars) before reaching sexual maturity. In spiders, very little is known about the male genital system, its development and seminal… Expand
Extreme convergence in egg-laying strategy across insect orders
- Julia Goldberg, Joachim Bresseel, +4 authors Sven Bradler
- Biology, Medicine
- Scientific reports
- 16 January 2015
The eggs of stick and leaf insects (Phasmatodea) bear strong resemblance to plant seeds and are commonly dispersed by females dropping them to the litter. Here we report a novel egg-deposition mode… Expand
Potential of X-ray micro-computed tomography for soft-bodied and gelatinous cnidarians with special emphasis on scyphozoan and cubozoan statoliths

Effects of starvation on reproduction of the predacious mite Neoseiulus californicus (Acari: Phytoseiidae)
- S. Toyoshima, P. Michalik, G. Talarico, Anja E. Klann, G. Alberti
- Biology, Medicine
- Experimental and Applied Acarology
- 1 March 2009
Effects of starvation on gravid females of Neoseiulus californicus were investigated at 20°C and 85% RH. When females that had been reared with abundant prey were swapped, just after laying their… Expand
Ultrastructural observations of spermatozoa and spermiogenesis in Wandella orana Gray, 1994 (Araneae: Filistatidae) with notes on their phylogenetic implications.
- P. Michalik, M. Gray, G. Alberti
- Biology, Medicine
- Tissue & cell
- 1 October 2003
Spermatozoa and spermiogenesis of the prithine filistatid spider Wandella orana are described. The spider produces coenospermia, i.e. sperm aggregations that include several single sperm cells… Expand
